No problem is too small or too trivial if we can really do something about it.

'Conservation' (the conservation law) means this ... that there is a number, which you can calculate, at one moment-and as nature undergoes its multitude of changes, this number doesn't change. That is, if you calculate again, this quantity, it'll be the same as it was before. An example is the conservation of energy: there's a quantity that you can calculate according to a certain rule, and it comes out the same answer after, no matter what happens, happens.

An ordinary fool isn't a faker; an honest fool is all right. But a dishonest fool is terrible!

One of the ways of stopping science would be only to do experiments in the region where you know the law. But experimenters search most diligently, and with the greatest effort, in exactly those places where it seems most likely that we can prove our theories wrong. In other words, we are trying to prove ourselves wrong as quickly as possible, because only in that way can we find progress.

The thing that doesn't fit is the thing that is most interesting.

If an apple was magnified to the size of the Earth, then the atoms in the apple would be approximately the size of the original apple.

The inside of a computer is as dumb as hell but it goes like mad!
