In this book author and former professor David Bodanis presents "the shocking true story of electricity." Actually this book is more about electrical devices through history and the scientists who created them. The electrical devices investigated are as follows: telegraph, telephone, light bulb, electric motor, radio, radar, and computer. Even human biological devices are looked into-specifically the nervous system and brain. Bodanis says this more eloquently:
"The world is made of electric charges and our technologies operate through electric charges, and even our brains are powered by electric charges."
The author does present some of the science behind electricity. (Electricity is a general term used for all phenomena caused by electric charge.) But he seems to concentrate only on DC or Direct Current (a term he never uses). (Direct Current is electric charge always flowing in the same direction.) Nothing (not one word!!) is said about the more important AC or Alternating Current and its colorful scientific history. This I feel was a major, major oversight. (Alternating Current is a flow of electric charge that periodically reverses its direction.)
Chapter 1 to chapter 6 of this 12-chapter book presents the scientific history of direct current. I feel Bodanis does a decent job here with his explanations and portraits of major scientists. In fact, I feel that his writing style is very engaging throughout the book.
The next two chapters discuss radar. Unfortunately, the author goes into way too much detail about the war effort and strays significantly off topic. I feel all this information was not needed.
Chapter 9 and chapter 10 discuss the idea of a "thinking machine" (what we now call the computer) and the man behind this revolutionary idea. As well, this man's legacy is explained. This information is well presented.
The last two chapters look into human biology. Here we learn that "our entire body operates by electricity." I found this information very interesting but felt that most of it was not relevant to the theme of the book.
There are two more brief sections at the end of this book. They are entitled as follows:
(1) "What happened next." This section profiles what happened to the major people mentioned in this book. Some of these people include Samuel Morse, Alexander G. Bell, Edison, Faraday, Hertz, and Turing. I found this section interesting.
(2) "Mr. Amp, Mr. Volt, and Mr. Watt." These units (amp, volt and watt) describe, according to Bodanis, "what's happening inside all...electric devices." What happened to Mr. Ohm? An ohm is a measure of electrical resistance. I thought not mentioning this unit was a major oversight.
Finally, there are no illustrations in this book. I felt simple diagrams would have reduced the book's wordiness. As well, pictures of some of the major people mentioned would have been nice.
In conclusion, this is a well-written book about electricity that has some major oversights and that, in some cases, presents irrelevant information.
