Robert O. Becker, the 20th century pioneer of research in bioelectric phenomena, does a masterful job of leading the reader into the invisible yet profound world of electromagnetism and its effect on all living organisms. At times awe-inspiring, at others frightening, Becker ends his book with more questions posed than answered, both in the realm of medical implications of tissue regeneration and in the realm of electropollution and its possible ramifications for our industrialized society. An excellent book for the intellectually curious.
