You have that one basic string, but it can vibrate in many…

One of the basic things about a string is that it can vibrate in many different shapes or forms, which gives music its beauty.

— Edward Witten

Having those extra dimensions and therefore many ways the string can vibrate in many different directions turns out to be the key to being…

Just like an ordinary guitar string, a fundamental string can vibrate in different modes. And it is these different modes of vibration of the…

The beauty of string theory is the metaphor kind of really comes very close to the reality. The strings of string theory are vibrating…

The central idea of string theory is quite straightforward. If you examine any piece of matter ever more finely, at first you'll find molecules,…

One very important aspect of string theory is definitely testable. That was the prediction of supersymmetry, which emerged from string theory in the early…

String theory is an attempt at a deeper description of nature by thinking of an elementary particle not as a little point but as…

I spent most of my career doing high-energy physics, quarks, dark matter, string theory and so on.

— Geoffrey West

We do not know how to formulate string theory nor do we know its underlying principles. Surprisingly, this fact does not stop us from…

Quantum mechanics brought an unexpected fuzziness into physics because of quantum uncertainty, the Heisenberg uncertainty principle. String theory does so again because a point…

My colleagues in elementary particle theory in many lands [and I] are driven by the usual insatiable curiosity of the scientist, and our work…

For five hundred dollars, I'll name a subatomic particle after you. Some of my satisfied customers include Arthur C. Quark and George Meson.

— Scott Adams

The laws of thermodynamics, as empirically determined, express the approximate and probable behavior of systems of a great number of particles, or, more precisely,…

I'm a fan of supersymmetry, largely because it seems to be the only route by which gravity can be brought into the scheme. It's…

Quantum physics fluctuates all the time. But now the fluctuations are not just particles coming into and out of existence, which happens all the…
