Over the years, I have enjoyed reading and at times subscribing to magazines with articles about science. Discover, Scientific American and National Geographic are some of my favorites. Having an interest in science and reading articles in popular magazines does not make me a scientist.

This much I know about science. It is not static. Scientific theories, as vigorous as they may be, can and do change. As an example, in the 17th century, Sir Isaac Newton wrote his famous principal about motion and gravity. It was not until the early 20th century, some 230 years later, that Albert Einstein’s General Theory of Relativity proposed that Newton’s Laws of Motion and Gravity were not entirely accurate. And 100 years later, scientists are working to prove or disprove Einstein’s relativity.
