To understand this new frontier, I will have to try to master one of the most difficult and counterintuitive theories ever recorded in the annals of science: quantum physics. Listen to those who have spent their lives immersed in this world and you will have a sense of the challenge we face. After making his groundbreaking discoveries in quantum physics, Werner Heisenberg recalled, I repeated to myself again and again the question: Can nature possibly be so absurd as it seemed to us in these atomic experiments? Einstein declared after one discovery, If it is correct it signifies the end of science. Schrödinger was so shocked by the implications of what he'd cooked up that he admitted, I do not like it and I am sorry I had anything to do with it. Nevertheless, quantum physics is now one of the most powerful and well-tested pieces of science on the books. Nothing has come close to pushing it off its pedestal as one of the great scientific achievements of the last century. So there is nothing to do but to dive headfirst into this uncertain world. Feynman has some good advice for me as I embark on my quest: I am going to tell you what nature behaves like. If you will simply admit that maybe she does behave like this, you will find her a delightful, entrancing thing. Do not keep saying to yourself, if you can possibly avoid it, 'But how can it be like that?' because you will get 'down the drain,' into a blind alley from which nobody has yet escaped. Nobody knows how it can be like that.

Working simultaneously, though seemingly without a conscience, was Dr. Ewen Cameron, whose base was a laboratory in Canada's McGill University, in Montreal. Since his death in 1967, the history of his work for both himself and the CIA has become known. He was interested in 'terminal' experiments and regularly received relatively small stipends (never more than $20,000) from the American CIA order to conduct his work. He explored electroshock in ways that offered such high risk of permanent brain damage that other researchers would not try them. He immersed subjects in sensory deprivation tanks for weeks at a time, though often claiming that they were immersed for only a matter of hours. He seemed to fancy himself a pure scientist, a man who would do anything to learn the outcome. The fact that some people died as a result of his research, while others went insane and still others, including the wife of a member of Canada's Parliament, had psychological problems for many years afterwards, was not a concern to the doctor or those who employed him. What mattered was that by the time Cheryl and Lynn Hersha were placed in the programme, the intelligence community had learned how to use electroshock techniques to control the mind. And so, like her sister, Lynn was strapped to a chair and wired for electric shock. The experience was different for Lynn, though the sexual component remained present to lesser degree...
