hypothesis, theory, and law

Contagious Yawns

This experiment is a chance for you to do some scientific research on a problem that has never been solved. We all yawn, and you have probably noticed that if someone else yawns, you do too. Why? There are several hypotheses, but none has enough solid evidence to become an accepted theory.

My Position on Science and Religion

Because I run a science education website, I get quite a few emails from people wanting to know my position on evolution/creation, the age of the Earth, and similar topics. These are very important questions, and I thought that this video might help.

After you watch the video, if you still have questions, you are welcome to email me. While I don't participate in hostile conversations, I am always delighted to have rational discussions on these topics.
