A Kitchen Course in Electricity and Magnetism (eBook)

J. David Nightingale has taught physics for over 30 years at SUNY New Paltz. More recently he has been a regular essayist for Northeast Public Radio, authoring many essays on famous scientists from history. Prof. Nightingale has previously co-authored the Springer book "A Short Course in General Relativity", now in its third edition.
