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.

25. Whenever two human beings spend time together, sooner or later they will probably irritate one another. This is true of best friends, married couples, parents and children, or teachers and students. The question is: How do they respond when friction occurs? There are four basic ways they can react:• They can internalize the anger and send it downward into a memory bank that never forgets. This creates great pressure within and can even result in disease and other problems.• They can pout and be rude without discussing the issues. This further irritates the other person and leaves him or her to draw his or her own conclusions about what the problem may be.• They can blow up and try to hurt the other person. This causes the death of friendships, marriages, homes, and businesses.• Or they can talk to one another about their feelings, being very careful not to attack the dignity and worth of the other person. This approach often leads to permanent and healthy relationships.
