"There are many reasons why you might not understand an explanation of a scientific theory Â… Finally, there is this possibility: after I tell you something, you just canÂ’t believe it. You canÂ’t accept it. You donÂ’t like it. A little screen comes down and you donÂ’t listen anymore. IÂ’m going to describe to you how Nature is - and if you donÂ’t like it, thatÂ’s going to get in the way of your understanding it. ItÂ’s a problem that scientists have learned to deal with: TheyÂ’ve learned to realize that whether they like a theory or they donÂ’t like a theory is not the essential question. Rather, it is whether or not the theory gives predictions that agree with experiment. It is not a question of whether a theory is philosophically delightful, or easy to understand, or perfectly reasonable from the point of view of common sense. A scientific theory describes Nature as absurd from the point of view of common sense. And it agrees fully with experiment. So I hope you can accept Nature as She is - absurd.
IÂ’m going to have fun telling you about this absurdity, because I find it delightful. Please donÂ’t turn yourself off because you canÂ’t believe Nature is so strange. Just hear me all out, and I hope youÂ’ll be as delighted as I am when weÂ’re through."
