This is not an extremely technical book. You would have some trouble trying to reproduce the good doctor's experiments with nothing but this. But it is very influential, and very interesting. A collection of the Biological works of Robert Becker would not only get 5 stars from me, but would be the greatest scientific work of the 20th century, with the POSSIBLE exception of Einstein's "Collected Works on Relativity". Yes, Becker is that good.
My first exposure to Becker was a relatively unimpressive interview on 60 minutes when I was a boy. In college I watched this man's work almost singlehandedly bring back electrobiology, which (so said the books printed in the 80's) was dead. There is still much to do in this field. It's rare for an MD (no, he is not a PhD) to be able to figure these things out without having someone else tell it to him. That's a compliment, by the way. Hell, MD's keep saying the Atkins diet won't work, when bodybuilders and wrestlers have been using the same principles very successfully for decades. They just aren't progressive thinkers for the most part, but this guy has more to say (that you need to hear) than any PhD around today.
His early article in the Journal of Bone and Joint Surgery(an early inspiration for my thesis) is cited here, as are several of his later articles, so it gives you leads to follow. If you are a scientist or are studying to be one, I recomend this as something very important to read between semesters. If you are a laymen that is either interested in science or just worried about the potential hazards of electromagnetic pollution, I recomend it as a starting point.
