Ed Purcell is probably one of the least famous but amazing expositor of Physics that I have come across. His book on electricity and magnetism (part of Berkeley Physics Course) is one of the best introductions to the topic (but again not very well known) Edit: Linking to the amazon page of the US edition, which seems to be out of print(http://www.amazon.com/Electricity-Magnetism-Berkeley-Physics...)

He also gave the classic talk "Life at Low Reynolds Number": http://brodylab.eng.uci.edu/~jpbrody/reynolds/lowpurcell.htm...

> I got into this through the work of a former colleague of mine at Harvard, Howard Berg. Berg got his Ph.D. with [Nobel Prize winner] Norman Ramsey

Norman Ramsey is also the name of a much younger yet contemporaneous Harvard professor of Computer Science (and a very prolific Stackoverflow answerer). (He is now at Tufts) I wonder how his name affected his career.

This is good to hear, Thank you! Edit: the picture on the cover is that of the electric field of an electron as it approaches the speed of light. This was the only book I know that actually tried to illustrate this..I simply love the beautiful illustrations :)

I used his book in my class.

Has anyone attempted to recreate the original Fermi problem? Fermi was in a bunker during the first nuclear test, and approximated the power by measuring the displacement of paper shreds due to the shock wave.

Does anyone know of any good books with these kinds of problems?
