What appear to be the most valuable aspects of the theoretical physics we have are the mathematical descriptions which enable us to predict events. These equations are, we would argue, the only realities we can be certain of in physics; any other ways we have of thinking about the situation are visual aids or mnemonics which make it easier for beings with our sort of macroscopic experience to use and remember the equations.

The chief difficulty of modern theoretical physics resides not in the fact that it expresses itself almost exclusively in mathematical symbols, but in the psychological difficulty of supposing that complete nonsense can be seriously promulgated and transmitted by persons who have sufficient intelligence of some kind to perform operations in differential and integral calculus.

The only important thing to realise about history is that it all took place in the last five minutes.

In an autocracy, one person has his way; in an aristocracy, a few people have their way; in a democracy, no one has his way.

Physics has never been a comfortable subject for human psychology. The desire to regard everything outside the human race's purview as insignificant, and everything within that purview as firmly under the control of tribal myth and custom, is as strong today as it was in the time of Galileo.

Research is a way of taking calculated risks to bring about incalculable consequences.
