Leon M. Lederman quotes:

Theorists write all the popular books on science: Heinz Pagels, Frank Wilczek, Stephen Hawking, Richard Feynman, et al. And why not? They have all that spare time.

The aether: Invented by Isaac Newton, reinvented by James Clerk Maxwell. This is the stuff that fills up the empty space of the universe. Discredited and discarded by Einstein, the aether is now making a Nixonian comeback. It's really the vacuum, but burdened by theoretical, ghostly particles.

By the grace of AEC, BNL, God, Green and Hayworth (alphabetical order), we should see neutrinos.

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.

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

A theoretical physicist can spend his entire lifetime missing the intellectual challenge of experimental work, experiencing none of the thrills and dangers - the overhead crane with its ten-ton load, the flashing skull and crossbones and danger, radioactivity signs. A theorist's only real hazard is stabbing himself with a pencil while attacking a bug that crawls out of his calculations.

I sometimes think about the tower at Pisa as the first particle accelerator, a (nearly) vertical linear accelerator that Galileo used in his studies.

Neutrinos ... win the minimalist contest: zero charge, zero radius, and very possibly zero mass.

During an intense period of lab work, the outside world vanishes and the obsession is total. Sleep is when you can curl up on the accelerator floor for an hour.

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

Particle physics suffers more from being infected by the socio-political mood of the day than from lack of spectacular opportunities for major and profound discoveries.

I'm so old I can remember when the Dead Sea was only sick.

One of the major ingredients for professional success in science is luck. Without this, forget it.

Science should have no less lofty a goal. My ambition is to live to see all of physics reduced to a formula so elegant and simple that it will fit easily on the front of a T-shirt.

The real goal of physics is to come up with an equation that could explain the universe but still be small enough to fit on a T-shirt

Theorists tend to peak at an early age; the creative juices tend to gush very early and start drying up past the age of fifteen-or so it seems. They need to know just enough; when they're young they haven't accumulated the intellectual baggage.

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

The physicists defer only to mathematicians, and the mathematicians defer only to God ...

Democritus's work on the void was revolutionary.

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'.....

I started out as a molecules kid. In high school and early college I loved chemistry, but I gradually shifted toward physics, which seemed cleaner - odorless, in fact.

Science is not about status quo. It's about revolution.

The sequence of theorist, experimenter, and discovery has occasionally been compared to the sequence of farmer, pig, truffle. The farmer leads the pig to an area where there might be truffles. The pig searches diligently for the truffles. Finally, he locates one, and just as he is about to devour it, the farmer snatches it away.

Those who do not stop asking silly questions become scientists.

When I talk about the pain and hardship of a scientist's life, I'm speaking of more than existential angst. Galileo's work was condemned by the Church; Madame Curie paid with her life, a victim of leukemia wrought by radiation poisoning. Too many of us develop cataracts. None of us gets enough sleep. Most of what we know about the universe we know thanks to a lot of guys (and ladies) who stayed up late at night.
