Site Overview

The www.dontow.com is the website of Don M. Tow. It contains articles in three topical categories (or pages): Political/Social Commentary, Taiji, and Other Topics.  Currently, a new release of this website is published usually every three months.  The website also has a fourth category “Soccer” about the soccer book that I published in 2006.

Any article in a particular category can be accessed via the corresponding category on the menu bar at the top of the page.  Any article in a particular release can be accessed via the corresponding release on the right sidebar.

This website began in October 2006, and the website has been redesigned twice, once in October 2008, and the second time in November 2009.

We welcome comments from readers.  Readers can directly submit their comments at the end of any article.

Criteria for Choosing an Exercise for Health

We all know that exercise is important for good health. The question is which exercise makes it appealing to people who would want to practice it on a regular basis. There are several criteria for choosing an exercise:

  • It is good for your health
  • It can be practiced in all kinds of environment, indoors or outdoors
  • It does not require fancy and large space
  • It does not require expensive equipment
  • It doesn’t cost a lot of money to practice
  • It is not very stressful or painful
  • It doesn’t require teammates to practice
  • It is something that you enjoy doing
  • It is an exercise that you can practice for many years, for all ages, from young to old
  • It is an exercise that can also help you in self defense.

This article discusses why Taiji can meet all of the above criteria. That is why it is a popular exercise around the world, especially in China. However, in my opinion, its potential should be able to attract an even larger group of practitioners, including young adults and children.

Paradoxes of Quantum Physics, Bell’s Theorem, and What Do Experiments Tell Us

Our previous article “Wonders and Mysteries of Quantum Physics” discusses how Quantum Physics (QP) [1] completely revolutionized our industrial world and our daily lives since its discovery about 100 years ago. Everyday we utilize a variety of products based on Quantum Physics. [2] That article also pointed out that QP introduced many mysteries, such as particle-wave duality, the act of observation can change what we are observing, uncertainty principle, our physical laws can only give us a probabilistic, and not a deterministic, prediction of the future.

These mysteries, especially the probabilistic interpretation, or a superposition of states, led many people to question from the beginning of QP around the mid 1920s whether there is a more fundamental theory than QT that would lead to a deterministic prediction. The most famous critic was Albert Einstein, who made critical comments such as “does the moon exist even when no one is looking at it” and “God doesn’t play dice.” Many people thought that there are probably physical variables that we are not aware of. Because these variables could have different values, and if we can determine their values, then we would have a deterministic prediction.

These are known as “hidden variable” theories. Even though the usefulness of QT became more and more apparent as more and more products based on QT permeated our lives, this debate never went away, partially because no one could think of any experiment that could be done to differentiate the predictions of QT and the predictions of hidden variable theories.

That ended in 1964 when the Irish physicist James S. Bell proved a remarkable but simple theorem (now known as Bell’s Theorem) that shows that Quantum Theory and local hidden variable theories can lead to different experimental results. [3] Therefore, this is no longer an academic debate, but a debate that can be decided by experiments, which is the fundamental concept behind physics. Before we discuss Bell’s Theorem and the subsequent experimental results, we need to make a digression to discuss two precursors of Bell’s Theorem.
