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 Copy Share Image
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 in the 20th century that the equations that work have inner harmony. — Edward Witten Copy Share Image
As for the forces, electromagnetism and gravity we experience in everyday life. But the weak and strong forces are beyond our ordinary experience. So… — Edward Witten Copy Share Image
“If one of the five theories describes our univers, who lives in the other four worlds” — Edward Witten Copy Share Image
The theory has to be interpreted that extra dimensions beyond the ordinary four dimensions the three spatial dimensions plus time are sufficiently small that… — Edward Witten Copy Share Image
You enter a completely new world where things aren't at all what you're used to. — Edward Witten Copy Share Image
On the other hand, we don't understand the theory too completely, and because of this fuzziness of spacetime, the very concept of spacetime and… — Edward Witten Copy Share Image
As of now, string theorists have no explanation of why there are three large dimensions as well as time, and the other dimensions are… — Edward Witten Copy Share Image
Technically you need the extra dimensions. At first people didn't like them too much, but they've got a big benefit, which is that the… — Edward Witten Copy Share Image
In Einstein's general relativity the structure of space can change but not its topology. Topology is the property of something that doesn't change when… — Edward Witten Copy Share Image
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 Copy Share Image
Even before string theory, especially as physics developed in the 20th century, it turned out that the equations that really work in describing nature… — Edward Witten Copy Share Image
I just think too many nice things have happened in string theory for it to be all wrong. Humans do not understand it very… — Edward Witten Copy Share Image
