30 Quotes by Sheldon Lee Glashow

The standard theory may survive as a part of the ultimate theory, or it may turn out to be fundamentally wrong. In either case, it will have been an important way-station, and the next theory will have to be better.

String theory's biggest prediction is that gravity exists. That's good. That's a lot more than preceding theories could do.

String theory has had a long and wonderful history. It originated as a technique to try to understand the strong force. It was a calculational mechanism, a way of approaching a mathematical problem that was too difficult, and it was a promising way, but it was only a technique. It was a mathematical technique rather than a theory in itself.

It's a wonderful honor to win an Ignobel Prize.

In 1969, John Iliopoulos and Luciano Maiani came to Harvard as research fellows. Together, we found the arguments that predicted the existence of charmed hadrons.

In 1956, when I began doing theoretical physics, the study of elementary particles was like a patchwork quilt. Electrodynamics, weak interactions, and strong interactions were clearly separate disciplines, separately taught and separately studied. There was no coherent theory that described them all.

I had more or less abandoned the idea of an electroweak gauge theory during the period 1961-1970. Of the several reasons for this, one was the failure of my naive foray into renormalizability.

Individual scientists cannot do much on their own. Heads of nations, corporates, and economic giants should recognise the criticality of it.

In the 1950s, the average person saw science as something that solved problems. With the advent of nuclear weapons and pollution, the idealistic aura around scientific research has been replaced by cynicism.
