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.
An Ode to Capacitors	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
Gauss's Law Song	No Magnetic Monopoles Song
Oersted Song (Including link to Techno version by Aziz Khan!)	A really nice DC motors demonstration
Right hand rule song (lyrics and chords)	Michael Faraday: Short biography Complete biography, written in 1872
Song & video about induction and transformers	Nikola Tesla: PBS website (very detailed!) Tesla Song: lyrics & chords .. mp3 (Guitar by Matt McCutchan)
The Mechanical Universe: Maxwell's Equations Free registration required. Choose episode 39.	Ampere's Law Song
This applet by Prof. Fu-Kwun Hwang shows you how sinusoids traveling in opposite directions superpose to make a standing wave.	The Mechanical Universe: Tacoma Narrows Bridge Collapse Choose episode 17 and watch 2:50-4:37 and 21:00-23:40.
