Laser Tweezers Movies: Chimp sperm .. chromosomes
(The chimp sperm movie I showed in class is the fifth one down on the above page. You may also be interested in the third one down; the researchers describe their methods and results. They explain the laser tweezers in a different way than I did in class, because they're addressing a more general audience.)

Charles Coulomb biography


Ben Franklin biography -- a must read!

"Benjamin Franklin Drawing Electricity from the Sky" by Benjamin West (1738-1820)

Coulomb's Law song (karaoke version!)

Electric Field Hockey! To get started, click on "Run Now". Arrange the positive and negative charges (drag them out of the supply) so that the puck goes into the goal. Be sure to click the buttons for "field" and "trace"!

Carl Friederich Gauss biography Note: Gauss did so much, especially in math, that you will not find his law explictly mentioned here! Instead, it is referred to as the "law of quadratic reciprocity". He originally derived it as a purely mathematical result for functions that fall off as 1/r^2, and then it was applied to the electric field.

Gauss in 1803
Here's a nifty two-dimensional electric fields and voltage applet. Use the slider bar to determine the strength and polarity of a charge, then click to place it. For me, the "Go" feature doesn't work well, since I can't see the charges while they're moving. But, the displays of the field configurations and equipotentials are pretty neat. Red equipotentials correspond to positive voltages (relative to the voltage infinitely far away) and blue to negative voltages.
