Change Quote by Edward Witten

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

— Edward Witten

Spreading out the particle into a string is a step in the direction of making everything we're familiar with fuzzy. You enter a completely…

Elementary particles are terribly boring, which is one reason why we're so interested in them.

— Steven Weinberg

You have that one basic string, but it can vibrate in many ways. But we're trying to get a lot of particles because experimental…

“Strings possess one defining property which is their tension. This quantity plays a crucial role in the overall picture of how strings can be…

— John D. Barrow

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

“Because string theory is such a high-risk venture—unsupported by experiment,”

— Lee Smolin

“Because string theory is such a high-risk venture—unsupported by experiment, though very generously supported by the academic”

— Lee Smolin

An elementary particle is not an independently existing, unanalyzable entity. It is, in essence, a set of relationships that reaches outward to other things.

— Henry Stapp

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

— Edward Witten

If string theory is a mistake, it's not a trivial mistake. It's a deep mistake and therefore kind of worthy.

— Lee Smolin

I will never probably have the mathematical foundation to truly understand what string theorists are talking about, but it feels good, just for its…
