My first work project is to help prepare an exam about electromagnetism. I've forgotten almost everything I knew about this subject, so I had to get a textbook from the library. I was most pleased to see my old friend "Electromagnetic Waves and Radiating Systems" by Edward Jordan and Keith Balmain. It is a delightful book, although a little dated. Luckily electromagnetic theory hasn't changed over the last 50 years, although labour relations, feminism and household appliances have come on a bit since the 50's, as demonstrated by the following quote from the book.
A man can do work for a 12-hour day at the rate of about 40 Watts, which is less than the power required to run his wife's electric washing machine.
