Ten years ago in 2010, I posted in this website a long article “Diao Yu Tai Student Movement: Recollection 40 Years Later”  . In this 50-year recollection article I will answer the above questions by extracting key summaries from the previous article and updating the discussion to take into account more recent events.
What Is the Issue?
The issue is the ownership of a set of small islands, called Diao Yu Tai (or Diao Yu Islands) in Chinese and Senkaku Islands in Japanese, in the East China Sea that is claimed by both China and Japan, and since the 1950s the official position of the U.S. government is that the territorial sovereignty of these islands is undecided, but the administrative rights of these islands were handed over in 1970 as part of the Ryukyu Islands (also known as Okinawa) by the U.S. to Japan. Although the U.S. states that these islands’ territorial sovereignty is undecided, it has also repeatedly said that the Treaty of Mutual Cooperation and Security between the U.S. and Japan would be applicable, thus leading to the possibility of war over these islands between the U.S. and China.
Historical and Legal Status of These Islands
Records of the Diao Yu Islands date back in maps of China to as early as 1403. The Diao Yu Islands are a group of eight small uninhabited islands located about 120 miles northeast of Keelung, the northern-most city in Taiwan, and about 240 miles southwest of Okinawa which is part of the Ryukyu Islands, and the water deepens significantly beyond the Diao Yu Islands heading toward the Ryukyu Islands.
During all these years Chinese fishermen had been fishing around these islands and also used them as temporary shelters. For several centuries the demarcation between the Ryukyu Kingdom and China always put the Diao Yu Islands as part of Taiwan, a province of China.
As the result of the first Sino-Japanese War of 1894 when China was defeated by Japan, China ceded the island of Taiwan to Japan, as well as paying a huge sum of money (equivalent to 6.4 times the annual Japanese government revenue or two-and-half years of Japanese government revenue depending on whose estimate). However, at the end of WWII, Japan accepted the terms of the July 26, 1945 Potsdam Declaration  which cited the November 27, 1943 Cairo Declaration  that stated that “all territories Japan has stolen from China, such as Manchuria and Taiwan shall be restored to the Republic of China (ROC).” The Japanese Instrument of Surrender that was signed on the deck of the USS Missouri on September 2, 1945 also explicitly referred to the Potsdam Declaration. On all these three occasions of the Cairo Declaration, the Potsdam Declaration, and the Japanese Instrument of Surrender, the ROC was represented.
It is perfectly clear historically and legally that the Diao Yu Islands belong to China, as part of the Taiwan Province. More information on this part of history can be found in Reference 1.
What Changed in the 1950s?
The case was very clear and there shouldn’t have been any question about which country should have sovereignty over the Diao Yu Islands. However, the international political environment changed with the establishment of the People’s Republic of China (PRC) after the Chinese Communist Party won the civil war over the Chinese Kuomintang Party. If it weren’t for the military support of the U.S. for Chiang Kai-shek’s government in Taiwan, Taiwan would have been united with the rest of China.
All of a sudden, China, instead of being an ally of the U.S., is now viewed as an arch enemy that needs to be weakened, isolated, and plotted against. On the other hand, Japan, the country that bombed Pearl Harbor in a surprise attack and committed massive, unimaginable inhumane atrocities in China and all over Asia, is now considered an ally of the U.S. to plot against China.
One of the first major manifestations of this new attitude occurred with the 1951 Treaty of Peace with Japan (commonly known as the 1951 San Francisco Peace Treaty), which was supposed to officially end WWII. This treaty was signed on September 8, 1951, and became effective on April 28, 1952. Fifty one countries participated in this conference, and 48 countries signed the treaty, which was basically drafted by the U.S. and the United Kingdom. Yet, China, the country in which Japan stationed the most soldiers and the country that suffered the most at the hands of the Japanese military, was not even invited to the conference, with the excuse that it was not clear whether the PRC or the ROC should be invited to the conference.
Unlike the various previously mentioned documents associated with the surrender of Japan at the end of WWII that explicitly stated that Taiwan and other Chinese territories stolen from China by Japan should be returned to China, the 1951 San Francisco Peace Treaty only said that Japan will relinquish those former Chinese territories, but did not explicitly say that they should be returned to China. This intentional twisting of history by the U.S. to the detriment of China has since been repeated on several occasions by U.S. senior government officials that the agreement was that Japan would give up their jurisdiction over Taiwan and other territories, but the receiving country of these territories was not specified. For example, Secretary of State John Foster Dulles, co-author of the San Francisco Peace Treaty, said in 1955 “the treaty ceded Taiwan to no one; that Japan merely renounced sovereignty over Taiwan, and that America cannot, therefore, admit that the disposition of Taiwan is merely an internal problem of China.” The PRC denounced the treaty and stated that it was illegal and should not be recognized.
Therefore, as early as 1951, it was already fairly clear about the imperialistic intention of the U.S. toward China and their planting the seed to ally with Japan to contain and weaken China.
In spite of the fact that neither PRC nor ROC was invited to the 1951 San Francisco Peace Treaty, a similar Sino-Japanese Peace Treaty (also known as the Treaty of Taipei) was signed by the ROC and Japan on April 28, 1952, the same day as the effective day of the 1951 San Francisco Peace Treaty. This Treaty of Taipei is basically the same as the 1951 San Francisco Peace Treaty, and it did not say that Taiwan and other Chinese territories stolen from China by Japan should be returned to China. The fact that the Treaty of Taipei was concluded so quickly and the fact that it essentially mirrored the 1951 San Francisco Peace Treaty strongly suggest that the chief orchestrator of this development was the U.S. The fact that the Treaty of Taipei did not say that Taiwan and other Chinese territories stolen from China by Japan should be returned to China also strongly suggests that the ROC government was weak and more interested in gaining the support of the U.S., and to a lesser extent Japan, than to defend the territorial sovereignty of China.
Who were representing or speaking for the Chinese? Furthermore, as the sole administrator under the U.N. of the Ryukyu Islands, the U.S. on December 25,1953 made the unilateral decision to include the Diao Yu Islands for the first time in the territory of the Ryukyu Islands, whose administrative control is scheduled to be handed over by the U.S. to Japan in March 1972.  The above described complicities by the U.S. helped to create a dispute which should not have existed in the first place.
More information on the 1951 San Francisco Peace Treaty and the 1952 Treaty of Taipei can be found in Reference 1.
What Triggered the Diao Yu Tai Student Movement in 1970?
In 1970, the U.S. and Japan were planning for the transfer to Japan of the administrative control of the territory of the Ryukyu Islands which since the 1953 unilateral decision of the U.S. included the Diao Yu Islands, both the PRC and the ROC objected to this agreement and argued that this agreement did not determine the sovereignty of the Diao Yu Islands. At that time, Japan and the U.S. had even more incentive to want to claim the Diao Yu Islands because within the previous few years, it was found that vast resources of oil could be under the area around these islands. Japan also sent troops to the islands to set up boundary markers, sent patrol boats to chase away Taiwan fishermen that have been fishing near these islands for centuries, and even tore down the ROC flag on the Diao Yu Islands.
When the oversea Chinese students heard about this, a grass-roots movement started and quickly spread around the world. It began in the fall of 1970 at Princeton University and at the University of Wisconsin at Madison. Quickly grass root organizations sprang up like new grass after a cool night of constant rain following a dry summer. For example, a Baodiao (or Protest Diao Yu Islands) organization was established at the University of California at Berkeley by early December 1970. Similar organizations sprang up overnight in many universities across the U.S., as well as in Europe, Hong Kong, Taiwan, Australia, and other parts of Asia and the world. What was remarkable was that these organizations separated in distance by hundreds or thousands of miles kept in constant touch with each other keeping in mind that that was several years before email became available and about a decade before the invention of the Internet.
This grass roots student movement energized Chinese students all over the world. Many of these student leaders labored days and nights educating themselves, putting on discussion meetings, organizing, producing newsletters providing background information on the issues, spreading the message to the media and local communities beyond the campuses (including buying a full-page ad in the May 23, 1971 issue of the New York Times), producing educational plays and musicals, and organizing protest rallies. Many were willing to sacrifice their studies and careers on the movement, and many ended up doing so. For those who did so, most of them did not regret and have not regretted when looking back many years later.
This movement has three targets:
The PRC government’s position has been consistently clear that the Diao Yu Islands belong to China. However, because those islands are part of the Taiwan Province, which was under the control of the ROC, the PRC government’s hands around the time of 1970 are partially tied in what they could do to protect the Diao Yu Islands from the infringement of Japan and the U.S.
Mirroring the Massive May 4, 1919 Chinese Student Movement
The famous May 4 Movement of 1919, which was initiated by Chinese students to protest against the grossly unfair treatment that the 1919 Versailles Treaty that ended WWI. Instead of returning the Shangdong Province to China after Germany was defeated in WWI, it was handed over to Japan. But instead of protecting the interest of the Chinese people and its country, the weak Chinese government was ready to acquiescence to the decision of Versailles. That so enraged the Chinese students that they burned the house of the minister of communications and assaulted China’s minister to Japan, both pro-Japanese officials. The slogans of the May 4 Movement were “Resist Foreign Powers” and “Rid Internal Traitors.” The student-led May 4 Movement quickly spread to workers, merchants, and businessmen and became a massive nationwide movement, and led to the Chinese representatives walking out of the Versailles Conference.
Although the May 4 Movement did not manage to achieve all their objectives as evident by the handing over of Shangdong Province to Japan, the movement did result in successes, such as the ability of China’s various social classes to successfully collaborate, an ideal that would be admired by both Nationalists and Communists. Furthermore, the May 4 Movement sparked national protests and marked the upsurge of Chinese nationalism, a shift towards political mobilization and away from cultural activities, and a move towards populist base rather than intellectual elites.
The Diao Yu Tai Movement that was initiated in 1970 used the above slogans as its guiding principle: “Resist Foreign Powers” and “Rid Internal Traitors.” The reason for the second part of that slogan is already clearly seen by how the ROC government immediately signed the Treaty of Taipei that mirrored the 1951 San Francisco Peace Treat. As another example, we only have to look at how the ROC government tried to snuff out the big Diao Yu Tai Movement’s protest rally in San Francisco on April 9, 1971. They wrote bad-mouth slogans on the student leaders on the fences of Portsmouth Square, site of the rally, and hired local youth gangs to try to disrupt that protest rally. Fortunately, the rally organizers were well prepared and its security people took care of the disrupting youth gangs and handed them over to local police.
Similar to the May 4, 1919 Student Movement, the Diao Yu Tai Movement of 1970 also has not yet achieved its objective of the Diao Yu Islands returning to Chinese sovereignty. However, it did achieve a major step toward that goal. The movement played a crucial role in persuading the U.S. government to adopt a position that although it was transferring the administrative rights of the Ryukyu Islands over to Japan, the territorial sovereignty of those islands is still to be determined.  Furthermore, it led the students not to be confined to the ivory tower, but to the workers and the community. It also expanded the students’ horizon to choose majors beyond science and engineering which were the majors of the majority of their predecessors, but to also social and political studies. It led them not just focus on intellectual pursuits, but also to social and political activism. These student leaders became involved in the movement when they were in the 20s, and some times in the early 30s. Many of them continue to be involved in various social and political activities for many years, including to their senior years.
Why Is the Diao Yu Island Movement Important for the American People?
Americans always claim to be standing on the side of justice. In the case of the Diao Yu Islands, it is crystally clear that China has always had and should continue to have sovereignty over the Diao Yu Islands.
Americans should not want to be dragged into a war with China in the East China Sea that has no moral or legal reasons to be involved. When the U.S. government has repeatedly stated that the territorial sovereignty of the Diao Yu Islands still needs to be determined, why should the U.S. government claim that the Mutual Defense Treaty with Japan should be applied to these islands? It is an obvious inconsistent policy that is based on the premise to weaken China and to use Japan as its pawn in that policy.
Yes, China has become the U.S.’s major competitor. On the one hand, we should let the two sides compete fairly. On the other hand, there are many important and urgent world-wide issues such as the pandemic, global warming, poverty, war and peace, and nuclear disarmament that the U.S. and China, the world’s two largest economies and most powerful countries, should collaborate with each other and with other countries to solve these critical issues. Otherwise, we may not have a planet to live in and survive.
Why Is This Movement Even More Important Now?
All the reasons just discussed in the previous session are still applicable. The U.S. is not on the side of justice in the case of the Diao Yu Islands. The dispute over the Diao Yu Islands may very well trigger a major war involving China and the U.S. that has no moral or legal basis.
With recent events, those and other reasons become even more important.
The U.S.’s reputation as a responsible world leader has fallen significantly in the last few years. President Trump has withdrawn the U.S. from the Paris Climate Agreement as the world is experiencing warmer climate, melting ice caps, more coastal flooding, more forest fires and violent storms. President Trump has also just withdrawn from the World Health Organization (WHO) as the world is facing a huge global pandemic, the worst one for at least the past 100 years. If we are the best and most powerful country in the world, then let’s work together with the world and lead the world to solve these problems.
Instead on focusing on solving the many grave problems faced by the U.S. due to the Covid-19 pandemic and the resultant economic collapse, the U.S. government is using a scapegoat, China, for its failures. We need to be brave enough and honest enough to admit that we contributed to these problems, instead of blaming all these problems on the Chinese. The best strategy to solve the pandemic is to work together globally to solve the pandemic because it is a global pandemic in a world that is intimately interconnected, and the virus does not recognize state or national boundaries.
Yes, China is the U.S.’s major competitor. As stated earlier, on the one hand, let’s compete with each other fairly. On the other hand, let’s see how we can grow the pie together. In the current world where countries are interconnected via fast planes, fast trains, and instant communications virtually through emails and the Internet, isolating ourselves via restrictive trade policies or restrictive virtual inter-connectivity is going to shrink the pie, and definitely is not going to grow the pie.
We also need to be more willing to share the pie, both domestically and globally. It cannot be continued that 10% of the U.S. population own 90% of the wealth of the U.S. Similarly, 10% of the people of the world cannot continue to own 90% of the wealth of the world. Otherwise, we will face continued turmoil both domestically and globally. We must find new ways to work together to grow the pie and to share the pie.
U.S. has already been involved in several questionable wars. Our country cannot afford another questionable war. We cannot afford it from a moral perspective, and we cannot afford it from a world leadership perspective. Furthermore, even from a purely economic perspective, we cannot afford it, because wars are costly and extremely destructive.
It is not an exaggeration that our children and grandchildren may be living in a world that will turn out to be much worse than our current world. With global pandemic, global warming, global poverty, and global arms competition, whether we will still have a livable planet 100 years from now is an alarming question. Countries of the world must work collaboratively to solve these big problems.

 Playing a crucial role in that persuasion was the Diao Yu Tai student movement’s lobbying efforts with the U.S. Senate that culminated in a key testimony in front of the Committee on Foreign Relations of the U.S. Senate on October 29, 1971 by representatives on behalf of the student movement. In particular, the representatives included Professor C. N. Yang (Physics Nobel Laureate), Professor S. B. Woo, and others. The end result was that a paragraph on Committee Action and a paragraph on Committee Comments were included in the Senate Executive Report No. 92-10, November 2, 1971 that read in part (see p. 5) “United States action in transferring its rights of administration to Japan does not constitute a transfer of underlying sovereignty (which the United States does not have), nor can it affect the underlying claims of any of the disputants. The Committee reaffirms that the provisions of the Agreement do not affect any claims of sovereignty with respect to the Senkaku or Taio Yu Tai Islands by any state.” Note: This Report should have used the spelling “Tiao Yu Tai Islands” or “Diao Yu Tai Islands,” instead of “Taio Yu Tai Islands.”]]>
One approach adopted by some schools to help young students to handle social and emotional health problems that may arise from this environment is the focus on mindfulness. In this article, we explain what mindfulness is, and in what ways Taiji can contribute to mindfulness.
The word mindfulness means that the mind is focused on the present task at hand, being aware of the environment but at least for that moment not overly anxious or worry by what is going on around us. Mindfulness can help a person concentrate on the current work, and not get distracted or overwhelmed by other events and the greater environment in which we live. Children attending school need to learn what the teacher is teaching them or the homework problem they are trying to solve, and at least for that moment do not worry about other things, such as that they may have sick siblings at home, or they may be bullied during recess, or their parents have been laid off.
The ability to concentrate is especially important when there is an observed increase among children experiencing ADHD (Attention Deficit Hyperactive Disorder), stress, depression, and even suicides . While our society and government need to remove certain underlying contributors to these problems, such as poverty, abuse, domestic violence, racial intolerance, and more recently a global pandemic, many school districts are also taking actions that are within their jurisdiction of responsibility and within their budgets to reduce the problems. One recent emerging method is the focus on teaching simple mindfulness techniques that can be integrated in the classrooms as well as perhaps when doing homework at home. 
Mindfulness is a general term and can mean many things. In this article, mindfulness refers to the ability to focus on the current task (or activity) and do not get distracted with many other tasks that may be waiting for us. Mindfulness is to train our mind to focus on the immediate task at hand, and at that moment lay aside other tasks that may be happening in our life. While we are working on the task at hand, we may get distracted, mindfulness will help us to get back quickly to the current task, i.e., quickly returning to the present moment. It can increase concentration and decrease stress.
A common technique of mindfulness is to focus on our breathing, e.g., teach the students to sit down comfortably, relax the body and mind, and focus on breathing in and out softly and slowly, paying special attention to the expansion and contraction of the tummy during the breathing in and out process. An enhancement of that technique is to use lower abdominal breathing (or deep belly breathing) in which the expansion and contraction become even more obvious. The mind is very conscious of our immediate environment, although extraneous thoughts are driven from the mind and forgotten at that moment.
Mindfulness also teaches students to think of positive thoughts, about themselves and others. They should think of pride and respect for themselves, show tolerance toward others, and display caring and respect for others.
When students are taught and practice mindfulness while in school, they can also utilize the technique when they are home. For example, before they do their homework, they can do the mindfulness exercise of relaxing with deep and soft breathing, with the mind focusing on the breathing and getting rid of extraneous thoughts. Not only that after such exercise, the mind can be more focused on the homework at hand, but they also feel less stressful.
Mindfulness is really an integral component of Taiji, where the body and mind are relaxed, where slow and relax deep breathing is practiced, and sensitivity and responsiveness of our bodily environment is enhanced. Most Taiji movements are soft and slow, especially in the Yang style Taiji. Slow and deep breathing is practiced (and once one advances beyond the elementary level, lower abdominal breathing is practiced). Furthermore, utilizing the ability to relax, the practitioner’s sensitivity via touch is increased to become more aware of the opponent’s movement as well as the opponent’s motive or intended movement, while at the same time the practitioner’s body is so relaxed, his opponent cannot sense the practitioner’s movement and motive or intended movement. This is why Taiji, besides being considered to be an exercise that is good for health, is also considered to be a good martial art.
Mindfulness is really a technique of meditation to relax our body and mind, to increase our concentration and reduce stress. Meditation is also an integral part of Taiji, not only while performing various Taiji form sets, but it is also part of various warm-up exercises to Taiji. That is why Taiji is also known as “meditation in motion.”
Taiji is such a wonderful exercise. It is a wonderful exercise for all ages. It is not only a good exercise for senior citizens, but also a good exercise for young people and children. Unfortunately, it has been overlooked, and more appropriately speaking, underappreciated for its value to children. With the emphasis on mindfulness for children, perhaps Taiji’s value to helping children to focus and relax can bring this age-old exercise to our young people. 
 According to a 2019 article in Psychology Today, suicides among children under the age of eleven more than doubled in the last ten years (https://www.psychologytoday.com/us/blog/wicked-deeds/201901/suicide-rates-even-among-children-are-rising-dramatically) .
 An example is the Saddle Brook School District in north NJ that started Mindfulness training in their schools starting shortly after online schooling went into effect in mid-March 2020:
 After this article was posted, a friend alerted me that recently an article “Subtle Motor Signs as a Biomarker for Mindful Movement Intervention in Children with Attention-Deficit/Hyperactivity Disorder,” Journal of Developmental & Behavioral Pediatrics: June/July 2020 – Volume 41 – Issue 5 – p 349-358. This medical research article reported that Taiji-based mindfulness training reduced core ADHD symptoms in children based on measurement of objective biomarkers of treatment. This research is also described in the article “Study finds Tai-Chi-based mindfulness training reduced core ADHD symptoms in children” by Kennedy Krieger Institute, in Medical Xpress, April 21, 2020.]]>
Quantum physics differs significantly from classical physics. Classical physics describe the physical laws governing the behavior of ordinary size objects that we deal with everyday in our lives – objects like a baseball, a bullet, a musical instrument like a violin, water waves on a beach or in an ocean. Quantum physics describe the physical laws governing the behavior of very small objects that we have to deal with in the subatomic world – objects like an electron, a proton, a neutron, a photon (the constituents of light). This article discusses some of the largest differences between quantum physics and classical physics, and the associated wonders and mysteries of quantum physics.
In classical physics, the objects that we deal with behave either like particles (e.g., a baseball, a coin) or like waves (e.g., a water wave, an air or light wave). Furthermore, an object is either a particle or a wave. But in quantum physics, the objects that we deal with have characteristics of a particle and characteristics of a wave. In other words, the subatomic objects behave both like a particle and a wave. This new and surprising discovery occurred through a series of experiments known as the double-slit experiments from the 19th century to the first quarter of the 20th century. 
Series of Crucial Experiments
First we discuss the double-slit experiment using a classical object like a bullet from a gun. In this double-slit experiment, there is a source producing the objects of concern, the bullets. Then there is a wall with two slits allowing the bullets to go through. With the exception of the two slits, the wall blocks the bullets. Finally, beyond the wall there are movable detectors mounted on the backstop, with the position of the detectors being movable. This experiment is shown in Figure 1: Double-slit experiment with bullets.
Figure 1: Double Slit Experiment 1 – With Bullets
(from The Feynman Lectures on Physics, Volume 3 – Quantum Mechanics, p. 1-2, Addison-Wesley Publishing Company, 1965)
The movable detector measures the probability of the bullet arriving at the location of the detector. The most likely position of the arriving bullet is the straight line from the gun source through the slit to the backstop. As a matter of fact, if you ignore that the slit is larger than the width of the bullet and a bullet could be deflected by the edges of the slit, the distribution function of the bullet at the backstop will be a delta function, i.e., showing 1 (i.e, 100% probability) at the x-position that is a direct straight path from the bullet source through the slit to the backstop, and zero everywhere else. Because the slit width is larger than the width of the bullet and the bullet hitting the edges of the slit could be deflected, the bullet can be deflected upward or downward with a smaller and smaller probability of arrival the farther the detector deviates from the straight line.
When we do the experiment with Slit 2 closed, the bullet can only go through Slit 1, we find that the probability distribution for the bullet arriving at different positions at the backstop is depicted as P1 (or P subscript 1) in the above diagram. Similarly, if we do the experiment with slit 1 closed, the bullet can only go through Slit 2, we find that the probability distribution for the bullet arriving at different positions at the backstop is depicted as P2 in the above diagram.
Now when we do this experiment with both slits open, we find that the probability distribution for the bullet arriving at different positions at the backstop is depicted as P12, which turns out to be exactly the sum of P1 and P2, i.e., the sum of the probability of the bullet going through Slit 1 and the probability of the bullet going through Slit 2. Saying it mathematically, there is no interference to the motion of the electron when a second slit is opened and allows it another path to reach the backstop. This behavior of objects like bullets is very much different from the behavior of objects like waves, as in water waves, sound waves, or light waves, which we now discuss.
We now perform a similar double slit experiment, but now the source is generating water waves, instead of bullets. and the detector is a gadget that measures the water wave intensity denoted as I, e.g., the height of the wave. This is illustrated in Fig. 2.
Fig. 2: Double Slit Experiment 2 – with Water Waves
(from The Feynman Lectures on Physics, Volume 3 – Quantum Mechanics, p. 1-3, Addison-Wesley Publishing Company, 1965)
Again, when Slit 2 is closed, the measured probability is shown as I1. Similarly, when Slit 1 is closed, the measured probability is shown as I2. However, when both slits are opened, the measure probability is shown as I12, which is definitely not the sum of I1 and I2. The reason is that with waves, the waves can go through both slits at the same time. Mathematically, the intensity of the water waves for I1 is the square of a complex function h1 (complex in the sense of real versus complex numbers), and the intensity of the water waves for I2 is the square of a complex function h2. Experimentally, it turns out that the Intensity I12 when both slits are opened is equal to the square of (h1+h2), and due to the cross terms, it is not the square of h1 plus the square of h2. This means that when both slits are open, there are interference terms (corresponding to the cross terms) because the waves can go through both slits at the same time.
Now, let’s do a third double slit experiment using electrons at the source and counters (such as Geiger counters) at the backstop. The counter in the backstop produces a sound to tell us that the electron has arrived at that location on the backstop.
Fig. 3: Double Slit Experiment 3 – with Electrons
(from The Feynman Lectures on Physics, Volume 3 – Quantum Mechanics, p. 1-4, Addison-Wesley Publishing Company, 1965)
Again, when we block Slit 2, the measured probability distribution at the backstop is shown as P1. Similarly, when we block Slit 1, the measure probability distribution at the backstop is shown as P2. However, when both slits are opened, the measured probability distribution surprisingly is shown as P12, which is not the sum of P1 and P2. As a matter of fact, if you compare Fig. 3 with Fig. 2 and Fig. 1, the distribution function of the electrons behaves just like the distribution function of water waves, and not like the distribution function of bullets.
Mysteries of Quantum Physics
This series of crucial experiments in the 19th century and first part of the 20th century led to one of the first mysteries found when we deal with very tiny objects like electrons of the subatomic world.
Mystery 1: The behavior of these subatomic objects like electrons behave very differently from macroscopic objects like bullets. Electrons exhibit wave-like properties (similar to what we saw with water waves as in our second experiment).
But this is not the only mystery when dealing in the subatomic world. We now discuss several more mysteries.
Now, if the electrons go through both slits at the same time, when we detect the electrons at the backstop, do we find only part of an electron? From the experiments, we found that the clicks that we hear from the counters in Fig 3 that detect the arrival of the electrons at the backstop are always the same. For example, we don’t hear any half clicks that perhaps indicate that only half of the electron arrived at that location and the other half might have arrived at another location, which may be what you would guess if the electron went through both slits. This means when you detect the electrons, you detect the whole electron, and not only part of the electron, i.e., electrons also behave like particles. This leads to:
Mystery 2: Subatomic objects, although displaying wave-like characteristics, also display particle-like characteristics. This is known as the wave-particle duality of quantum physics., i.e., subatomic particles display both characteristics, showing behavior like a wave, and also showing behavior like a particle.
There are more mysteries of quantum physics. From the previous experiment, we saw that electrons behave with wave-like properties in the sense that they seem to go through both slits at the same time, and they don’t just go through slit 1 or slit 2.
Can we try to detect which slit the electron went through? We know that electric charges scatter light. Since electrons are charged particles, if we put a light source behind the wall, we should be able to determine the path the electron took by observing the location of the scattered light. So let’s do an experiment as depicted in the next figure.
Fig. 4: Enhanced Double Slit Experiment with Electrons and a Detecting Light Source
(from The Feynman Lectures on Physics, Volume 3 – Quantum Mechanics, p. 1-7, Addison-Wesley Publishing Company, 1965)
In this experiment, if the electron went through Slit 2, we should see a flash of light coming from the vicinity of location A in the above diagram. Similarly, if the electron went through Slit 1, we should see a flash of light coming from the vicinity of a location above the light source. If we see flashes of light coming simultaneously from both spots, then we can conclude that the electron went through both slits at the same time.
So when this experiment was done, what did we observe? Whenever we hear a click from the counter at the backstop, we also see a flash of light either near Slit 1 or near Slit 2, but never both. Furthermore, with this experimental setup, the probability distribution observed at the backstop is no longer P12 of Fig. 3, but P12Prime of Fig. 4 (which is similar to P12 of experiment 1), i.e., there is no longer any interference.
What does this mean? When we observe the location of the scattered light to determine the path of the electron, the observing light gave some momentum to the electron and disturbed the path of the electron and changed the original distribution pattern. If you keep on reducing the momentum of the observing light passed on to the electron (by reducing the light frequency or increasing its wavelength), then when you increase the wavelength more and more, you increase more and more the uncertainty on the position of the scattered light. When you reach the point of being unable to detect the location of the electron, the distribution pattern at the backstop also changes back from P12Prime of Fig. 4 to P12 of Fig. 3! This leads to the following:
Mystery 3: The act of observance can change what you are observing. This is understandable for the experiments discussed above because in order to observe, you need to use light. In order to give more precision to what you are observing, you have to use smaller and smaller wavelengths (or larger and larger frequencies of light), which is equivalent to imparting larger and larger momentum to the electrons and therefore results in larger and larger disturbance to the path of the electrons.
This also leads to:
Mystery 4 Heisenberg’s Uncertainty Principle – One cannot simultaneously measure precisely the position and momentum of any object (first proposed in 1927 by the German physicist Werner Heisenberg).
This uncertainty principle applies not just for the position and momentum of any object, it actually applies for any pair of complementary (or conjugate) variables, like time and energy of an object. Furthermore, it is an intrinsic limitation of nature, and not just due to inadequacy of the accuracy of our current experiments.
The uncertainty principle leads to one of the most significant and puzzling implications of quantum physics: Something may be created from “nothing.” We often think of a vacuum as made up of empty space. However, if we are talking about an extremely tiny interval of time, as at the moment of the Big Bang when our current universe was created, then the uncertainty principle tells us that the uncertainty in the involved energy could be very large, large enough to create electron and positron pairs, or mater and anti-matter pairs to form stars and galaxies. This is known as vacuum polarization or vacuum fluctuation. That means that things may be created from the nothingness in a vacuum.  However, solving this mystery of creating something from nothing leads to another great mystery that currently we have no clue of solving, i.e., why is there not an equal amount of matter and anti-matter, instead of our observed universe which is made up of essentially only matter.
Predictability of Quantum Physics
In classical physics, if we are given the initial conditions of an object, then using the laws of physics, we can predict precisely the future behavior of an object. However, in the subatomic world, because particles have wave-like characteristics, we can no longer predict precisely the behavior of an object even if given the initial conditions.
Mathematical digression: The physical state is described by a complex wave function (complex in the mathematical sense of real versus complex numbers), which we denote as C (or the Greek letter phi ϕ in Fig. 3). The distribution function is determined as the square of C. In the double slit experiment, when only Slit 1 is open, that function is C1. When only Slit 2 is open, that function is C2. When both slits are opened, the distribution function is the square of the sum of C1 and C2, which is not the same as the sum of C1 squared and C2 squared. When you do this square calculation, there will be cross terms involving both C1 and C2. These cross terms are the interference terms coming from the fact that the wave can go through both slits 1 and 2.
Because in quantum theory, the state of an object is described by a wave function, we can calculate only the probability distribution of the future, and unlike classical physics where we can calculate precisely the object’s future state. This leads to another mystery of quantum physics.
Mystery 5: In the subatomic world, we can only predict the probability distribution of certain physical happenings in the future.
As we stated at the beginning of this article, on the one hand quantum physics has introduced many wonders and has revolutionized essentially all aspects of our lives. It has introduced all kinds of gadgets, like vacuum tubes, transistors, TVs, computers, video games, medical imaging, cell phones, GPS, Internet, nuclear weapons, missiles, and so on. However, on the other hand, quantum physics has also led us to many mysteries, like the wave-particle duality and the probability interpretation of quantum physics. That has led many people, including Albert Einstein, to make the remark that God does not play dice and question whether there is a more fundamental theory than quantum theory so that the uncertainties. can be removed and the theory can then be deterministic, and not probabilistic.
Interpretations of Quantum Theory
As just stated, the probabilistic interpretation of quantum theory has led many people to feel that quantum theory cannot be the ultimate theory of physics. For example, perhaps there are some hidden variables that we are not aware of and therefore we have not defined their values. In the future, if we can figure out what these hidden variables are and determine their values, then we can remove the uncertainties and our physical theory then becomes deterministic. This is known as the hidden variable theory.
In 1964, the Irish physicist John Bell proved a very simple theorem that states that all local hidden variable theories  cannot make the same predictions as quantum theory. Therefore, one can perform experiments to prove whether quantum theory or local hidden variable theory is correct.
Even though Bell’s Theorem is one of the most important and remarkable theorems in physics, it is relatively simple to prove. As a matter of act, the proof takes only a few pages and uses nothing more than high school mathematics.
In a future article, we will discuss Bell’s Theorem and the experiments that have been done which so far have shown that quantum theory is the correct theory.  Also, in another future article, we will discuss the quantum entanglement from the wave function description of quantum theory and its implications for encryption in quantum computers.
 The discussion that we use in this article follows closely the lectures of Richard P. Feynman, in The Feynman Lectures on Physics, Volume 3, by Feynman, Leighton, and Sands, Addison-Wesley Publishing Company Inc., Palo Also, 1965. This series of lectures came from the lectures that Feynman gave for the freshman and sophomore physics courses at Cal Tech in 1961-1963. Although they were intended for college freshmen and sophomores, they have been valuable references for many graduate students.
 On the subject of Heisenberg’s Uncertainty Principle and creating something from the vacuum via vacuum fluctuations, there is a good and interesting science documentary “Everything and Nothing: What is Nothing? – 2019 (https://www.youtube.com/watch?v=gXbIzc3bcT8). This is part of a series of science documentaries by Professor Jim Al-Khalili.
 Bell’s Theorem applies only to hidden variable theories that are local, i.e., no information can be transmitted faster than the speed of light.
 Another good and interesting science documentary of Professor Jim Al-Khalili’ series of science documentaries is “The Secret Of Quantum Physics: Einstein’s Nightmare” – 2019 (https://www.youtube.com/watch?v=f_4nYgrDJvc). This discusses the double slit experiments, the mysteries of quantum physics, and Bell’s Theorem.]]>
Two persons, one a Chinese citizen and one a Japanese citizen, have done the most to lead this movement so that justice can be restored and history will not be forgotten. This article provides a short summary of these two people, Tong Zeng (童增) of China and Tamaki Matsuoka (松岡環) of Japan.
Tong Zeng (童增) – Who Speaks for the Voiceless: Although millions of Chinese people suffered great atrocities under the Japanese military in the form of massacres, rapes and kidnapped comfort women, slave laborers, biological and chemical weapon attacks, vivisection as POWs. The instigators never admitted to their guilt and basically never punished. The victims never received any apology and were never financially compensated for their sufferings.
When China and Japan established diplomatic relationship on September 29, 1972, in the interest of the friendship between the Chinese and the Japanese people, China, as a gesture of good will, renounced its demand for war reparation from Japan, i.e., the Chinese government no longer required the Japanese government to pay reparation for the damages it did to China during WWII and the Second Sino-Japanese War.
As a young man studying for a masters degree in law, Tong Zeng investigated various international legal cases and issues regarding compensation related to atrocities committed during a war by one country on the citizens of another country. He concluded that there are “war reparations” and “damage compensations.” The former, “war reparations,” are compensations for the losses that the defeated countries launching the war caused to the countries they invaded. The latter, “damage compensations” are compensations for the sufferings and losses of the people of the invaded countries caused by acts of the invading militaries violating the laws of war and humanitarian principles.
In July 1990 he wrote a White Paper “China Demands Japan to Compensate Atrocity Victims.”  Although initially he received no interest in any newspaper on the contents of his White Paper, on March 31, 1991 he got the newspaper Ming Bao in Hong Kong to post a short article about it. Then a couple of days later, he distributed copies of his White Paper to various delegates on their way to attend the National People’s Congress (NPC) in Beijing. Several delegates showed interest in his proposal. Although it was too late to discuss this in the 1991 NPC, it was taken up as a topic of discussion in the 1992 NPC. When news of this discussion was reported in the mass media, it ignited a brush fire across the whole country.
Seeking compensation for the atrocities committed by the Japanese military was a long-overdue item for seeking justice and closure that has been buried in the hearts and souls of thousands and thousands of Chinese atrocity victims and their relatives. During the next few years, thousands of people wrote to Tong Zeng endorsing and thanking him for his proposal and wrote to him providing details of the atrocities that they or their family members had experienced. Within a few years, he had received about 10,000 such letters.  This became an archive of letters of historical significance that document the atrocities experienced by the victims and written by the victims or their close relatives.
Here are excerpts of a few sample letters that were sent to Tong Zeng starting in the 1990s .
Written on 12/15/1992 by Tang Qiangshen of Zhejiang Province, with the first part of the quote referring to air bombing: “More than 8,000 people died from being buried alive, burning to death, freezing, boiling with hot water, cramming pepper water, poisoning, attacking by hounds, starving, body splitting by horses (all kinds), hanging, skinning, mutilation, (gang) raping, live targets of shooting and flesh carving. … After the Japanese army retreated in May 1945, 25 shoulder pole loads of human bones were excavated, more than 2,700 skeletons were discovered across the area. … 18 women were raped (gang raped) before death, over 500 women were raped by brutal force; these women were stripped and raped in broad daylight, and “teased” before being raped, some even died from splitting the body with knife.”
Written on 11/20/1992 by Tang Qingyu of Kunming, Yunnan Province: “In 1941 when the Japanese Army invaded Western Yunnan, after Baoshan was conquered, large crowds of residents living in Baoshan and other places in Western Yunnan swarmed to Kunming to avoid slaughter by the Japanese Army. Immediately afterwards cholera broke out in Kunming. At first people thought it was epidemic plague, but soon it spread to the whole city. Those contracted cholera first would have symptoms of vomiting and diarrhea, and soon they died in less than one day. On the streets one could see dead people each day. Back then at the biggest and most famous coffin shop (the boss was surnamed Zhao) on Wenmiao Street in Kunming, all the coffins were sold out. … The Japanese army spread cholera bacteria in Western Yunnan, therefore the fleeing people of all social circles brought the cholera bacteria to Kunming and spread it around. … As mentioned above, the number of civilians suffering direct or indirect damage from the Japanese Army runs to thousands and millions. Newspapers published at that time all carried the story.”
As the result, Tong Zeng became the leader of the whole grievance and compensation movement in China. For example, he helped to establish and became the Chairman of the Chinese People’s Association for Compensation Against Japan. He gave voice to the thousands and millions of voiceless Chinese atrocity victims and provided an organized force to seek apology, justice, and compensation from the Japanese government, as well as those Japanese companies who were involved in slave laborers.
One of the accomplishments of this organized force is the negotiated settlement between former Chinese slave laborers of Mitsubishi Materials Corporation (or Mitsubishi for short) and Mitsubishi that was reached on 6/1/2016. The negotiated agreement included:
More than 70 years after the war ended, a portion of the atrocity victims finally received justice and compensation. However, this is only a small portion of the millions of atrocity victims. Much more hard work remains in the years ahead.
The thousands of letters that Tong Zeng received from atrocity victims were accumulated and kept in many boxes in his office.
When years and years have gone by and there was still no apology and compensation from Japan, Tong Zeng was worried such important archives could be lost from history with a theft or fire. So he tried to find a method of safe-keeping these letters. In early 2014 when a couple of Chinese Americans in the U.S. heard of this dilemma, they offered to work with Tong Zeng to develop a website to keep and post all the letters, including digitizing all these letters and translating a subset of the letters into English. This led to a joint collaborative project between a small Chinese team, led by Tong Zeng and his able assistant Meng Huizhong (孟惠忠), and a small Chinese American team of volunteers. After almost two years of hard work working almost days and nights, the initial website called “10,000 Cries for Justice” was completed, and this important historical archive has been posted in a bi-lingual website www.10000cfj.org. This important historical archive is now safe from loss due to thefts or fires. This website (the current address of this website is now “https://2018.10000cfj.org) is still being worked on, as only a small percentage of the letters have been translated into English. The goal is to eventually translate all these letters into Japanese also.
Because of the political climate at that time when China was still trying to establish diplomatic relations or build up its friendship with many countries, Tong Zeng did not always have the support of the Chinese government in what he was doing. As a matter of fact, when certain important visitors, e.g., Japan’s Prime Minister, were visiting Beijing, Tong Zeng’s employer, the National Committee on Aging, would arrange an out-of-town business trip for him so that he was not around Beijing just in case he would cause trouble.
As stated earlier, the whole compensation movement is far from completed, Tong Zeng and many other similar leaders will continue to work hard to restore justice and seek compensation for millions of other atrocity victims, so that all the voiceless victims can be heard and rest in peace.
Tamaki Matsuoka (松岡環) -The Conscience of Japan: One of the largest atrocities that the Japanese military inflicted on China was the Nanking Massacre which occurred for approximately six weeks starting from December. 13, 1937 to near the end of January 1938. During these six weeks, approximately 300,000 Chinese, most of them civilians and many were women and children, were slaughtered, and over 20,000 Chinese females (women, girls, and even very young girls and great grandmothers) were raped, and one third of the city of Nanking was burned to the ground.
Tamaki Matsuoka was born in Japan in 1947, and was an elementary school teacher. As she was growing up and as a young adult, she was taught and heard many different versions about the Nanking Massacre, including that it was fake and fabricated by the Chinese. So starting in the mid 1980s, she decided that she was going to find out for herself what really happened during the Nanking Massacre.
She did and spent more than 30 years of her adult life to find out just exactly what happened in Nanking during those six weeks. An ambitious and formidable task even for a person working full-time on such a project. But Tamaki had to earn a living working full-time as an elementary school teacher, and also together with her husband raising a family with two sons. She was able to work on this project only during the summers, school holidays, or weekends. Initially she only had herself to work on this project, and she had to pay for any incurred expenses (e.g., travel expenses between Japan and China). Furthermore, she endured a lot of criticisms and attacks from the Japanese right wing, including death threats.
But she endured this difficult, challenging, and dangerous journey. The journey was not easy at all. She exhibited courage, dedication, commitment, and sacrifice to achieve her objective. Among other accomplishments, she interviewed over 250 former Japanese soldiers who participated in the Nanking Massacre and over 300 Chinese survivors of the Nanking Massacre.
Even after establishing some initial contacts with former Japanese WWII veterans after posting an announcement in Japanese newspapers, she had to overcome significant cultural and political reluctance to talk about this sensitive subject. Again it took months or even years of building friendship with these veterans and gaining their trusts in the importance of the project that the veterans were willing to open up and discuss these long-held memories which they had not discussed with anyone else (including their immediate family members) for over half a century. Similarly, she had to overcome significant reluctance for the survivors to revisit the long suppressed terrifying dark memories of the past, including cultural reluctance to discuss being raped, and political reluctance to discuss atrocities committed by Japanese soldiers when at times the Chinese government was trying to establish friendlier relationship with the Japanese government.
By comparing notes of the perpetrators and victims, Tamaki matched up records and compiled testimonies of the mass slaughter, rape, arson, destruction, plunder and other unimaginable violence committed to the Nanking residents including women, elderly and children. Her work produced numerous presentations, research articles, films and several books, including winning the “Japan Congress of Journalists Prize” in 2003. A summary of her life-long project is summarized in the English book Torn Memories of Nanking , which should be a must-read book for everyone.
Thanks to her and others , the true picture of Nanking Massacre is gradually being revealed to the world with irrefutable evidence. Through these testimonies, there is an undeniable case for the existence of the Nanking Massacre as one of the most horrific atrocities in the history of humankind.
The best way to get a good sense of the Nanking Massacre is from interview statements that Tamaki recorded from Chinese survivors and Japanese soldiers. Here is a small sampling from her published English book.
How could humans use such atrocious treatments toward other humans? Although a complete explanation may not be found from the interview statements, they do mention some of the reasons.
I want to end this section on the Nanking Massacre with a quote of Mitani Sho, an 18 year old Japanese soldier whom Tamaki interviewed: “Until now, I had no opportunity to tell my story. After sixty years, I can finally give my testimony. I am extremely grateful. As a Japanese, I often reflect deeply on this episode. Today, however, many Japanese deny that the Nanjing Massacre or military sexual slavery took place. What kind of people are they? These people are trying to find an excuse to slowly change the interpretation of the Japanese constitution. Today, they are establishing a large military, and completely revamping the armed forces. In addition, they are trying to place the Japanese Army under U.S. command as an allied army that is prepared to fight American wars. Under a new security treaty and guidelines, Japan would be automatically pulled into any wars that the U.S. started. If such a situation were to arise, it is possible that events like the Nanjing Massacre could happen again. If we do not clearly state the historical truth and admit to this truth, we will not be able to establish a peaceful world for ourselves and our families.”
That is why Tamaki Matsuoka is known as “The Conscience of Japan.” 
Ending Remarks: Seventy fives years have transpired since the Second Sino-Japanese War ended in 1945. We must acknowledge what happened during that war, we must learn from that painful experience, so that that painful experience will not have to be endured by anyone else in this world in the future.
We must, like Tong Zeng, continue to speak for the voiceless. We must, like Tamaki Matsuoka, continue to spark the conscience of Japan.
I hope the following comments will be used to guide us in the future:
 You can find this White Paper (both English and Chinese versions) at “An Archive of Historic Cries for Justice Letters”: http://www.dontow.com/2015/09/an-archive-of-historic-cries-for-justice-letters/
 In the early 1990s when the majority of these letters were sent to Tong Zeng, many relatives and Chinese media personnel borrowed many of these letters. Because at that time copying machines were not readily available to Tong Zeng and other people in China, many of these letters were borrowed and unfortunately, most of them were never returned. That is why Tong Zeng now has only about 5,000 letters.

A person with better health is in general less likely to become susceptible to getting sick, whether the illness is due to the new coronavirus Covid-19, or some other illness. Taiji is already known to give rise to a lot of benefits for health.  A 2019 article  has shown that modern scientific research during the past 25 years or so has provided preliminary confirmations of this long-standing belief; that article also provided an explanation why Taiji can give rise to such health benefits. A brief summary of that journal article can also be found in a recent article posted in this website. 
Therefore, the reasons that Taiji can give rise to all those health benefits can also be applied to why Taiji can be beneficial in preventing or overcoming any illness associated with the new coronavirus.
|Our discussion in this article will focus on the reasons associated with oxygen and blood circulation, stress reduction, correct posture, exercising your muscles, tendons, and ligaments, and increased immunity.|
Good health requires adequate supply of oxygen to various parts of our body. Although Taiji movements are soft and slow, Taiji is an aerobic exercise that provides oxygen and stimulates blood circulation. Taiji exercises your heart and lungs. It synchronizes with breathing, especially with lower abdominal breathing for experienced practitioners, and brings in more oxygen. Lower abdominal breathing also massages the internal organs inside your abdomen.
The fundamental principle of Taiji of relaxation can reduce stress. It is emphasized in almost every aspect of Taiji, including associated meditation exercises. Relaxation reduces anxiety, hypertension, diabetes, and ADHD. It soothes the mind, leads to better sleep quality, and reduces various bodily pains. On the one hand, it relaxes the mind, but on the other hand the mind is involved and leads the forms, and that may be why Taiji can slow down the onslaught of Alzheimer’s Disease.
Another fundamental principle of Taiji is to keep your upper back straight. This guiding principle manifests all throughout the Taiji movements and results in good posture. This guiding principle together with the emphasis on keeping your feet separated by a shoulder width lead to better balance and stability.
Taiji movements, as well as various accompanying warmup exercises such as the Eight Silk Brocade  or the self-massaging Paida exercises  stretch and strengthen your muscles, tendons, and ligaments, and increase flexibility. These exercises stimulate air and blood circulation throughout your body, and also strengthen all parts of your body, thus increasing your immune system.
As a matter of fact, more than 15 years ago, Taiji was found that it can increase immunity to shingles, caused by the reactivation of the chickenpox virus (the varicella-zoster virus, or VZV). Taiji can increase a person’s immunity by as much as taking the shingles vaccine VARIVAX. Furthermore, if a person takes the VARIVAX vaccine, practicing Taiji can increase that person’s immunity even more. 
Since Covid-19 is caused by a virus, increasing a person’s immunity is key to avoiding being infected with Covid-19, or recovering from it if one has been infected. Increasing one’s immunity, together with other health benefits, practicing Taiji can be an important part of our defense against the current global pandemic.
With the current global pandemic, we are faced with lockdown and staying at home. My personal experience has found that in some sense, this has been a blessing. Without the need to attend various activities outside of the home, and without needing to spend the time to drive to these activities, I find that I now have more time than before.
My Taiji practice takes about one hour per practice. But the practice consists of various components, such as warm-up stretching exercises, meditation exercises such as Eight Silk Brocade and Standing Meditation, Forms such as the Mixed-Style 42 Form or the Yang-Style 24 Form, and strength-building exercises. The components take about 15-20 minutes each, and could be as little as 5-10 minutes. Therefore, while I am preparing dinner, I can exercise one component, then while baking in the oven, or steaming in a wok, or cooking in a pressure cooker, I can do another component. Since all these activities are done at home, I can easily go from one activity to another. The end result is that I have found more time to do my Taiji practices on a more regular basis.

This is my reply to your 4/29/2020 email asking me for a donation for your presidential campaign and the Democratic Unity Fund.
First, let me say that I am a strong critic of President Trump and I would like to support Mr. Biden to be the next President of the U.S. and other Democratic candidates running for office in the 2020 election.
I think we are offered a golden opportunity to defeat Trump and to remove from office many incumbent national, state, and local Republicans. The main reason is due to the performance track record of Trump and the whole Republican Party during the last 3 years and 4 months:
The above track records provide ample reasons for removing Trump and his Republican yes-people from power, and provide critical and convincing arguments to choose Mr. Biden over Trump. If Mr. Biden and the Democratic Party would seize and focus on this poor performance record of Trump and the Republican Party, then you will be able to defeat Trump and the Republican Party come this November.
However, if Mr. Biden and the Democratic Party would try to outdo Trump in his bashing of China as in Mr. Biden’s recent “Unprepared” ad , then Mr. Biden and the Democratic Party will be unable to seize this golden opportunity, because instead of attacking Trump’s poor performance record where he is so vulnerable, your trying to outdo Trump in his bashing of China is not based on facts, and furthermore you are supporting Trump’s scapegoat excuse for his mistakes and incompetency.
China did not create the new coronavirus. On 12/31/2019, about a month after mysterious illnesses first appeared in Wuhan, China, the Chinese government alerted the WHO about these mysterious illnesses. On 1/11/2020, Chinese scientists posted to the world the genome of the mysterious new virus (now known as COVID-19). This led shortly after to WHO developing a template for preparing tests. Then many countries (such as Germany and South Korea) used this information to successfully develop diagnostic tests for COVID-19. Unfortunately, our country did not use the WHO template, and instead tried to develop our own test which took a long time to develop and the initial tests did not work.
Yes, China made some mistakes in its initial handling of this new mysterious infection, but it is understandable that such mistakes could have easily occurred in light of the newness of this infection. Just look how the U.S. and other countries on multiple occasions have revised their statistics and understanding of the origin and methods of spreading of this virus.
Almost on every step of the way, Trump has completely mismanaged our country’s response to COVID-19. After wasting about more than two months of critical time, he tried to cover up his own mistakes and find a scapegoat in China.
If Mr. Biden follows the same path, he is essentially validating Trump’s excuse and incorrectly and unfairly putting the blame on China. Furthermore, the kind of ads like “Unprepared” is not convincing and is unlikely to gain the support of other Democrats and undecided voters, and definitely not any Trump supporter.
Another consequence is that you help to create phobic against China and Chinese Americans, as well as Asian Americans. This just contributes to more racism in our country. Does Mr. Biden want to scare away and lose the votes and support of Chinese Americans, as well as Asian Americans which is the fastest growing racial/ethnic group in the U.S.
Mr. Biden and the Democratic Party need the votes and support of a cross spectrum of Americans, including a progressive coalition as well as younger voters. Your campaign must be based on criticizing the lousy performance record of Trump and the Republican Party, instead of finding a scapegoat in China.
Mr. Biden, do you want to seize this golden opportunity and provide leadership and hope to restore our great country as the beacon of the world, or do you want to go down in history as the person who caused this great country to suffer through another four years of Trump?

Due to the coronavirus, the world is facing a pandemic and a major economic downturn. This is happening all over the world, but the implications for the U.S. may be the greatest in terms of the American people’s health, the country’s economy, and the upcoming political elections. A lot of these are the results from the actions of President Donald Trump.
This article has 4 sections. Part I has Sections I and II, and Part II has Sections III and IV.
This article first summarizes significant timelines of the coronavirus (Section I). Then it discusses several of President Trump’s specific remarks or actions with respect to the coronavirus (Section II). Then it discusses the implications of these remarks and actions upon the health of the American public, the people’s livelihood and their pocket books, and the impacts on this fall’s American elections (Section III). The article ends with some comments on the need to eliminate discriminatory double standards (Section IV).
Because this article is long, we have separated the article into Part I and Part II. This is Part I (placed in the “Political/Social Commentary” page) and includes Sections I and II. Part II (placed in the “Other” page in this same March 2020 release of this website) includes Sections 3 and 4.
Section I: Significant Timelines
Before we discuss President Trump’s actions and various impacts, we first provide a timeline of significant events during the last four months.
In summary, in 3-4 months, the new coronavirus has spread rapidly all over the world. It is going to get worse before it can get better. It is going to take drastic national and international leadership to overcome this pandemic. Currently in only a few countries, like China and S. Korea, the situation seems to be stabilizing and improving (e.g., significant reduction in the number of new infections, or the number of recovered cases becomes more and more than new cases).
Section II: President Trump’s Significant Remarks or Actions
As our country’s top leader, what President Trump does or says has tremendous impacts on the directions and operations of the whole governing apparatus of the country, and therefore on the livelihood, physical and mental health, and spirit of the citizens of this country, including the pocketbooks of our citizens and the bottom lines of our businesses. Therefore, let’s recall many of President Trump’s actions and words since the beginning of 2020 when the new coronavirus became known to the U.S. and the world.
1. On 1/22/2020, the day after the first coronavirus case was confirmed by the CDC, President Trump, when asked “are there worries about a pandemic at this point,”‘ in a CNBC TV interview at the World Economic Forum in Davos, Switzerland, responded “No, Not al all. And we have it totally under control. It’s one person coming in from China, and we have it under control. It’s going to be just fine.”
2. On 1/24, Trump again told Americans that there was no reason to worry, and “it will all work out well.” On 1/30 in a speech in Michigan, he said “We have it very well under control. We have very little problem in this country at this moment — five. And those people are all recuperating successfully.”
3. On 1/31, the day after the WHO declared the coronavirus a global emergency, President Trump put on a travel restriction on China, to and from China, effective starting on 2/2/2020. This was a positive step, but it was far from enough as clearly shown below.
4. On 2/10 on 3 different occasions, Trump made the remark “Looks like by April, you know, in theory, when it gets little warmer, it miraulously goes away.” However, his statement is not supported by science or infectious disease experts in his administration, and presently there is no indication that the coronavirus may diminish significantly with warmer weather, like the common flu.
5. On 2/19, Trump told a Phoenix TV station “I think the numbers are going to get progressively better as we go along.” Four days later he said the the situation is “very much under control” and “we had 12, at one point. And now they’ve gotten very much better. Many of them are fully recovered.”
6. For several weeks starting around mid February, President Trump and some of his officials on several occasions said that testing is available to anyone who wants such a test. That was just not true, although that statement was repeatedly made. First, the testing kit was not available to anyone who wants a test. It was not necessarily available even if a doctor has prescribed such a test and the patient has symptoms of the infection. The testing kits were only distributed by the CDC to selected agencies. Furthermore, there was a serious problem with these test kits because the tests were not accurate. The U.S.’s development of their test kit should be compared with what S. Korea did, who has been offering free testing of about 10,000 people per day since the middle of February, with a test cost of about $20 each. Furthermore, in S. Korea once a test has been proven in the laboratory, normally it takes a long time (e.g., many months) to get it approved for general use for the public. In the case of the coronavirus test kit, it got approval in one week!  It is a little unclear what is the cost of each test. It is $20 according to the first article in Ref. , but the cost is listed as $134 in Ref. .
The federal government via CDC and FDA (Food Drug Administration) set down very strict guidelines on who can prepare such test kits, diallowing reputable research labs on the forthfront of such research to conduct more general testing even when they have shown success in their laboratory. More information on this problem is described in .
7. Even on 3/6 after a briefing in a visit to CDC in Atlanta, Trump mentioned again that “anyone who wants a test can get a test.” But that evening at the White House VP Pence, who is leading the administration response, knows better and would not commit to that, but said doctors treating potentially symptomatic Americans could contact local officials and have state labs do the testing.
8. Dr. Anthony Fauci, Director of the National Institute of Allergy and Infectious Diseases, has repeatedly said that the test program that CDC has been working on has not met what has been advertised, and in a testimony in Congress on 3/11 said that any vaccine for the coronavirus is at least a year to a year and a half away.
9. On 3/11 evening, in a nationwide address from his White House desk, Trump for the first time acknowledged the seriousness of the coronavirus situation in the U.S. and that the problem is not going away soon. At this time, the whole country was cancelling large gatherings including the NCAA basketball tournament and the NBA, and everyone was planning to cancel various gatherings, including schools and even medium size gatherings. Yet, in his speech there was no mention or guidance on this important issue.
The only major action announced by President Trump was additional traffic restriction from and to Europe, effective starting at midnight 3/13. Even on that, President Trump made three important mistakes. One mistake in his announcement is that the restriction does not apply to Americans who are returning from Europe. That caused a lot of anxiety for Americans who were in Europe at that time, and caused many of them taking very expensive flights home. The second mistake is that the restriction applies only to people, and does not apply to trade and cargo. The third mistake is that Ireland was also exempt, just like Great Britain. But there was no explanation for the announced exception, even though Great Britain has more infections than some of the other countries in Europe. Just like many decisions of Trump, his decisions are arbitrary, and not well thought out.
His justification for the travel restriction is that there are more infections today in Europe than in the U.S., but ignoring that perhaps we have lower infections may be due to our behind in the testing. There was no mention of any other step to reduce the seriousness of the coronavirus.
It is then not surprising at all that on the next day on 3/12, the DJIA dropped by 2,352 points (or 10%), the worst drop since 1987.
10. On 3/13 afternoon, reacting to the large dissatisfaction shown all over the country to his performance on his 3/11 nationwide address and to the next day’s huge market drop in the stock market, President Trump gave another nationwide address from the White House. He declared a national emergency that will provide $50 billions to fund various support programs. He waived interest on student loans.
Together with a large group of CEOs, he also announced a series of measures to help protect the health of our citizens, e.g., Walmart and Target would allow their parking lots to be testing sites. Trump also made two mistakes in his announcement. One mistake is that he said that insurance companies will waive all copays for coronavirus treatments. In reality, insurance companies only agreed to waive the copays for coronavirus testing. The second mistake that he said that Google has 1,700 engineers working to develop a website to help people find a test location. In reality, Verify, a subsidiary of Google’s parent company, Alphabet, with a total workforce of only 1,000 people is working on a website related to the coronavirus. More information about this disparity can be found in .
Declaring a national emergency is necessary, and some of the proposed actions are necessary. However, what President Trump said was again full of false information or half truths. Furthermore, in response to a question, Trump said he is not responsible for any delay, even though it was his administration who in May 2018 canceled the pandemic preparedness office within the National Security Council, and for the 2021 budget proposed a budget cut of 15% (or $1.2 billion) for the CDC and a $35 million decrease to the Infectious Diseases Rapid Response Reserve Fund. Again, he doesn’t admit to mistakes and loses more credibility.
The stock market did rise significantly (by almost 2,000 points for the DJIA). However, about half of that gain occurred during the last hour of trading when there was a lot of news that House Speaker Nancy Pelosi and Treasury Secretary Steven Mnunchin were very close to reaching a large relief package in Congress.
11. On 3/16, President Trump in another nationwide address mentioned that the Federal Reserve the day before has reduced interest rate to almost 0%. He emphasized that people should avoid any gatherings of more than 10 people and to practice group distancing, and acknowledged that the coronavirus may not reach a peak until July or August.
In spite of reducing the interest rate to almost 0% and the prospect of Congress passing a significant relief package, the stock market crashed. For example, the DJIA dropped by almost 3,000 points on 3/16, and has dropped by 29% since 1/1/2020. Again, this is not surprising, because testing is still not yet widely available, implying that the situation will get even more worse, and the whole country is almost closing down, thus basically shutting down all business, and it is going to cause the government to spend a large amount of money to keep people above water, thus increasing significantly the federal deficit and the national debt
Nevertheless, in a response to a question, President Trump rated himself 10 on a rating of 1 to 10.

 S. Korea’s test was based on a WHO template which is available to the world.

More information on this can be found in the following two articles: (1) “How this South Korean company created coronavirus test kits in three weeks” by I. Watson, S. Jeong, J. Hollingsworth and T. Booth, CNN, March 12, 2020. (2) “How South Korea Scaled Coronavirus Testing While the U.S. Fell Dangerously Behind” by S. Engelberg, L. Song and L. Dephillis, ProPublica, March 15, 2020.

In the 2014 edition of the document “Crisis Emergency Risk Communication” published by the CDC that first came out under George W. Bush’s presidency (2001-2008), the subheading is “Be First. Be Right. Be Credible.”  On page 2 of that document, besides those three principles, it added three more, and states “Throughout this book, six principles of effective crisis and risk communiction are emphasized:
Unfortunately, President Trump during the coronavirus crisis has not exhibited any of these six principles. As a matter of fact, he has exhibited the opposite of these six principles:
This has been clearly shown and documented in Section II (Part I) of our article. As a matter of fact, the previous section has clearly shown that President Trump has completely mismanaged the whole coronavirus crisis; he has repeatedly lied and dispatched completely false information or at best half truths; he does not understand the problem, and doesn’t allow the appropriate knowledgeable people to run with managing the crisis. He has completely underestimated the problem, and wasted several weeks of valuable time to attack the problem.
Actually this kind of behavior is typical of President Trump during his whole presidency on almost everything he has done. He has always lied, provided no legitimate reasons for his deeds and words, he has always attacked and made fun of other people, showing no compassion or understanding of other people’s circumstances, and he often does not take actions to try to solve problems in a timely manner, if at all. Yet, it seems that he remains popular to his loyalists and a portion of the American public. It doesn’t seem that in the past he has lost a lot of his popularity. Is it different now?
Yes, it is different with the coronavirus emergency. In the past, his deeds and words did not affect the people loyal to him, at least not in the near term. Life can go on as usual.
However, in the current coronavirus crisis, everyone’s health and life could be affected. In other words, our own existence could be terminated. Furthermore when the whole society is basically shutting down, you may no longer be able to work, go to school, have any recreations, visit your friends and relatives, including not even being allowed to go outside of your own home. You may end up with no job, no income, your savings and all your assets may evaporate with the crashing stock market and the shutting down of all industries. In addition, the government is so heavy in debts due to massive relief programs and great reductions in income from taxes, putting all future generations at risk.
Anyone, including the Trump loyalists, can see the adverse impacts on themselves. Even the wealthy people, including the top 1-2 % rich people can see their wealth diminishing rapidly and their whole lifestyles for themselves and their children disappearing before their eyes. Perhaps sooner or later, even the Republican political leaders at the federal,/state/local levels may decide that blindly following Trump may not be good for their own political careers.
I think we are beginning to see that now. You can sense that from the people around you. including Republicans. You can sense that some cracks may be emerging from the Republicans around you, and even among the Republican political leaders. Right now, the polls show that Democrats are much more concerned about the coronavirus crisis. However, since in all likelihood, the coronavirus crisis in the U.S. and most other parts of the world is going to get worse before getting better. Sooner or later when the crisis impacts their and their family members’ health, livelihood, and their pocketbook, they will be very much concerned about the coronavirus crisis, and will understand that blindly following Trump is not going to lead them to see light at the end of the tunnel.
I think this change in mood and assessment of President Trump is already reflected in the recent Democratic primary election.
Of course, this was for the Democratic Party. We won’t know until the election in November. My guess is that this attitude will be pervasive across the whole country, and Trump will be defeated in November.
We end this section with some suggestions:
IV: Comments on the Need to Eliminate Discriminatory Double Standards
Yes, the new coronavirus was first found in Wuhan, China in late 2019. It then spread rapidly to other parts of China and then to the rest of the world. But it was not a virus that China purposedly spread to other parts of the world. China is as much a victim as other countries of the world. As a matter of fact, China so far has suffered the most infections and deaths than any other country.
Even though China should have better handled the initial warning of a new epidemic, China did quickly share its information with the world, including Chinese scientists posting on 1/11/2020 the genome of the mysterious new virus. That information quickly led to the WHO and other countries to develop a template for preparing tests. Such testing kits resulted in quickly testing and controlling the spread of the virus in countries like S. Korea, Germany, and Singapore. That is why the WHO has repeatedly praised China on its actions.
Instead of repeatedly focusing on a mishap during the initial moments of a new and confusing mysterious development, the world should also remember how quickly China share the information on the genome of the new virus determined by Chinese scientists that led to the quick development of widely available test kits. We should focus on how we can work together to attack this new global problem.
While facing this massive challenge of a new and rapidly spreading deadly disease, the Chinese government adopted draconian measures to isolate Wuhan. Instead of trying to understand why the Chinese government adopted such measures, many people outside of China quickly criticized China to adopt such undemocratic steps limiting people’s livelihoods and personal liberties.
A good example of discriminatory double standards is how the New York Times depicts the lockdown around Wuhan in a 3/8/2020, 10:30 AM article and a similar lockdown around northern Italy in another 3/8/2020, 10:50 AM article (20 minutes later). In the former, it describes the measure “at great cost to people’s livelihoods and personal liberties,” while in the latter, it describes the measure as “an effort to contain Europe’s worst coronavirus outbreak.” 
An example of a choice of racist words is the Wall Street Journal‘s February 3, 2020 editorial article titled “China Is the Real Sick Man of Asia.” The WSJ still has not apologized for such use of racist words.
Another example of racist words is President Trump referring to the coronavirus as the “Chinese Virus” made in a speech on March 16, 2020. Even though in the past, some illnesses were named after certain locality or origin, times have changed and now we should be more careful with such designations. For example, before 1978 hurricanes were named only with women’s names. That has changed. You would expect that the president of the U.S. would be more sensitive so his comments would not lead to more unwarranted racist attacks on Chinese Americans.
With such usage of racist remarks and double standards by the NYT, the WSJ, and President Trump, is it then surprising to see so many random attacks on Chinese Americans on the streets of the U.S.? This is another lesson we should learn from the coronavirus crisis.

By Taiji-like exercises we are referring to exercises that include warm-up exercises that we usually do at the beginning of each class or self-practice , and breathing/stretching/meditation exercises like the Eight Silk Brocade Qigong  exercises. We will discuss two types of people with limited mobility handicaps:
I. People Seated in Wheelchairs: These are people who are seated in wheetchairs, but can still move their arms and legs. There are still quite a few exercises that these people can do. We now discuss several of them.
II. People with Limited Mobility Capability: This set of exercises is for those who can stand up and walk, although slowly and not always steadily. When walking, be sure to pay attention to the following two principles as discussed in Ref. 3:
For these people, all the exercises discussed in Section I for people in wheelchairs can also be done by people who can stand up and walk. Besides the three Eight Silk Brocade Qigong exercises discussed in Section I, they can also do the other five Eight Silk Brocade Qigong exercises of Ref. 2. Furthermore, while doing these exercises, they can also squat down if it is prescribed by the exercise.
In addition, here are a couple more exercises they can do:
In summary, people with limited physical mobility can also do many Taiji-like warm-up, stretching, and Qigong exercises, and thus benefit from many health benefits of Taiji. These are relatively simple exercises and can be taught and learned easily. They do not require a lot of room. The exercises can be practiced for extended periods like 30-60 minutes, or as short as 10-15 minutes. Practicing them several times per week will do wonders to your health and increase your vitality and raise your spirit.
