Physicists like to think that all you have to do is say, these are the conditions, now what happens next?

It is not unscientific to make a guess, although many people who are not in science think it is.

It is scientific only to say what is more likely and what less likely, and not to be proving all the time the possible and impossible.

The "paradox" is only a conflict between reality and your feeling of what reality "ought to be."

A great deal more is known than has been proved.

The Quantum Universe has a quotation from me in every chapter - but it's a damn good book anyway.

There is no learning without having to pose a question. And a question requires doubt.
