The only way to have a scientific theory is if the laws of physics hold everywhere, including at the beginning of the universe.

Stephen Hawking (1994)



Although there have been suggestions that spacetime may have a discrete structure, I see no reason to abandon the continuum theories that have been so successful.

Stephen Hawking (1996)



The theory of gravitation … stands isolated from the other theories. Gravitation is, so far, not understandable in terms of other phenomena.

Richard Feynman (1985)



If you calculated something roughly, it would give a reasonable answer. But if you tried to compute it more accurately, you would find that the correction you thought was going to be small … was in fact very large―in fact, it was infinity!

Richard Feynman (1985)



So when some fool physicist gives a lecture at UCLA in 1983 and says, “This is the way it works, and look at how wonderfully similar the theories are,” it’s not because Nature is really similar; it’s because the physicists have only been able to think of the same damn thing, over and over again.

Richard Feynman (1985)



Physics must be simple.

Jean Eisenstaedt (2006)



It is clearly the first of the physical sciences because the whole of physics makes use of it; it is the science of the foundations of physics.

Jean Eisenstaedt (2006)



Sometimes ignorance is a good thing.

Jean Eisenstaedt (2006)



…continuum …should be banned from the theory as a supplementary construction not justified by the essence of the problem, which corresponds to nothing “real”.

Albert Einstein (1916)
