Leonard Susskind Quotes
-
The standard SU(3)×SU(2)×U(1) theory of strong, electromagnetic, and weak interactions appears to correctly describe physics down to the smallest distance scales yet probed.
-
The success of ordinary cosmology speaks against the idea that the universe was created in a random fluctuation.
-
There is a philosophy that says that if something is unobservable -- unobservable in principle -- it is not part of science. If there is no way to falsify or confirm a hypothesis, it belongs to the realm of metaphysical speculation, together with astrology and spiritualism. By that standard, most of the universe has no scientific reality -- it's just a figment of our imaginations.
-
Extra dimensional theories are sometimes considered science fiction with equations. I think that's a wrong attitude. I think extra dimensions are with us, they are with us to stay, and they entered physics a long time ago. They are not going to go away.
-
Over the years, I began to understand that there were a lot of people out there reading physics in popular literature that they could not understand - not because it was too advanced, but because it wasn't advanced enough.
-
The word 'universe' is obviously not intended to have a plural, but science has evolved in such a way that we need a plural noun for something similar to what we ordinarily call our universe.
-
(Jokingly) Sex in ten dimensions is impossible... topologically.
-
I was from a poor Jewish family in the South Bronx. My father was a plumber, but when I was 16, he got sick and I had to take over. Being a plumber in the South Bronx wasn't fun.
-
I'm not going to argue with people about the existence of God. I have not the vaguest idea of whether the universe was created by an intelligence.
-
You have to say now that space is something. Space can vibrate, space can fluctuate, space can be quantum mechanical, but what the devil is it?
-
Unforeseen surprises are the rule in science, not the exception. Remember: Stuff happens.
-
Man - life in general - seems irrelevant to the workings of the universe: a mere smudge of water, grease, and carbon on a pinpoint planet circling a star of no special consequence.
-
There is so much to groak; So little to groak from.
-
Space can vibrate, space can fluctuate, space can be quantum mechanical, but what the devil is it? And, you know, everybody has their own idea about what it is, but there's no coherent final consensus on why there is space.
-
A lot of my research time is spent daydreaming - telling an imaginary admiring audience of laymen how to understand some difficult scientific idea.
-
Every time a bit of information is erased, we know it doesn't disappear. It goes out into the environment. It may be horribly scrambled and confused, but it never really gets lost. It's just converted into a different form.
-
Science to me is sufficiently weird and interesting, and stranger than fiction.
-
I'm doing physics because I'm curious about how it works - full speed ahead, damn the torpedoes, don't worry about whether somebody is going to be able to do an experiment next week, just figure it out.
-
We often say that the earth is a sphere, but to be precise, the term sphere refers only to the surface. The correct mathematical term for the solid earth is a ball.
-
I was going to engineering school but fell in love with physics.
