The British philosopher Bertrand Russell said that philosophy went downhill after Democritus and did not recover until the Renaissance.

He [Democritus] is probably best known for two of the most scientifically intuitive quotes ever uttered by an ancient: 'Nothing exists except atoms and space, everything else is opinion'.

Physics isn't a religion. If it were, we'd have a much easier time raising money.

My children have often asked me why I never received a Nobel Prize. I used to tell them it was because the Nobel committee couldn’t make up its mind which of my projects to recognize.

Where do we stand today compared to Greece circa 400 B.C.? Today's experiment-driven 'standard model' is not all that dissimilar to Democritus's speculative [sic] atomic theory.

We hope to explain the entire universe in a single, simple formula that you can wear on your T-shirt.

Experimenters don’t come in late—they never went home.
