It is not often that one has the tremendous joy of discovering a very good book, but this is the experience I had unexpectedly when I began to read this one, because in principle I had only expected to find a common piece of superficial historical literature.

It is undoubtedly the best history I know of the development of ideas and theories about electricical and magnetic phenomena AND of the experimentation, development and use of empirical procedures and machines in the same field. I value most the wide and equilibrated coverage of subjects, the precision of the provided data and the almost complete lack of void fraseology. Only so can one accomplish the incredible feat of the author of putting the whole of it into 337 pages. There are a selected number of good references and good indexes.

Pure gold!

I am a student in Berkeley CA. One day my teacher asked us if we knew anything about Heinrich Hertz. No one knew anything. I felt bad so I decided to do some research on his life. I found out many interesting facts- when I opened this book up. It wasn't until I read this book that I fully understood the life and liberty of this great man. I loved it. The whole world knows his name but doesn't know how his life really effected us.
