Problem Solving Advice from Prof. Suzanne Amador Kane	Math Appendices -- Helpful mathematical material collected by Haverford and Bryn Mawr Physics majors some years ago, edited by Lyle Roelofs. (See also the math summary on Moodle.)
Charles Coulomb biography 1736-1806	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", "Antialias" and "trace". The black vectors show the direction of the field, but not its strength. The blue vectors coming out of the puck show the forces from the negative charges, while the red vectors show the forces from the positive charges. Try varying the mass!
Coulomb's Law song (karaoke version!)	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.
