29 quotes by Edward Witten

Edward Witten (/ˈwɪtən/; born August 26, 1951) is an American theoretical physicist and professor of mathematical physics at the Institute for Advanced Study in Princeton, New Jersey. Witten is a researcher in string theory, quantum gravity, supersymmetric quantum field theories, and other areas of mathematical physics. In addition to his contributions to physics, Witten's work has significantly impacted pure mathematics. In 1990 he became the...

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

Even before string theory, especially as physics developed in the 20th century, it turned out that the equations that really work in describing... →

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

I don't care about movies. I tend to play badminton once a week.

I'm actually, for the most part, a complete agnostic politically.

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 physicists have... →

If I take the theory as we have it now, literally, I would conclude that extra dimensions really exist. They're part of nature. We don't... →

I wouldn't have thought that a wrong theory should lead us to understand better the ordinary quantum field theories or to have new insights about... →

We know a lot of things, but what we don't know is a lot more.

As for the forces, electromagnetism and gravity we experience in everyday life. But the weak and strong forces are beyond our ordinary experience. So... →

But the beauty of Einstein's equations, for example, is just as real to anyone who's experienced it as the beauty of music. We've learned... →

As of now, string theorists have no explanation of why there are three large dimensions as well as time, and the other dimensions are microscopic.... →
