1 " 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. "
2 " The purpose of a thought-experiment, as the term was used by Schrödinger and other physicists, is not to predict the future - indeed Schrödinger most famous thought experiment goes to show that the " future," on the quantum level, cannot be predicted - but to describe reality, the present world.Science fiction is not predictive; it is descriptive.Predictions are uttered by prophets (free of charge), by clairvoyants (who usually charge a fee, and are therefore mor honored in their day than prophets), and by futurologists (salaried). Prediction is the business of prophets, clairvoyants, and futurologists. It is not the business of novelists. A novelist's business is lying.
