Physics is Phun!

Physics is Phun and Hair Raising!

I love the physical sciences and enjoy teaching chemistry and physics. I try to show the Secrets of the Universe to my students every year. This site will help me to impart information to my students (and anyone else who visits) to help them with their classes and to learn a bit more science.

In the photo above, I am in contact with a van de Graaf generator, which is producing an excess of charge in my body. The excess charge consists of the same type (either all positive or all negatve) and thus repels the other like charges. The excess charge on my hair, while repelling each other, makes my hair spread apart as well. This illustrates that electric repulsion (and also electric attraction) is a very strong force - even stronger than gravity.
