might strings theory
So when you ask me how string theory might be tested, I can tell you what's likely to happen at accelerators or some parts of the theory that are likely to be tested.
physics strings theory
String theory is 21 st century physics that fell accidentally into the 20th century.
world used new-world
You enter a completely new world where things aren't at all what you're used to.
change introducing bigs
It's indeed surprising that replacing the elementary particle with a string leads to such a big change in things. I'm tempted to say that it has to do with the fuzziness it introduces.
teamwork everyday together
As far as extra dimensions are concerned, very tiny extra dimensions wouldn't be perceived in everyday life, just as atoms aren't: we see many atoms together but we don't see atoms individually.
strong cousin progress
Superstring theories provide a framework in which the force of gravity may be united with the other three forces in nature: the weak, electromagnetic and strong forces. Recent progress has shown that the most promising superstring theories follow from a single theory. For the last generation, physicists have studied five string theories and one close cousin. Recently it has become clear that these five or six theories are different limiting cases of one theory which, though still scarcely understood, is the candidate for superunification of the forces of nature.
agnostic
Im actually, for the most part, a complete agnostic politically.
knows
We know a lot of things, but what we don't know is a lot more.
nature simplicity physics
Even before string theory, especially as physics developed in the 20th century, it turned out that the equations that really work in describing nature with the most generality and the greatest simplicity are very elegant and subtle.
uncertainty-principle doe principles
Quantum mechanics brought an unexpected fuzziness into physics because of quantum uncertainty, the Heisenberg uncertainty principle. String theory does so again because a point particle is replaced by a string, which is more spread out.
important strings theory
One very important aspect of string theory is definitely testable. That was the prediction of supersymmetry, which emerged from string theory in the early '70s.
real nice believe
I just think too many nice things have happened in string theory for it to be all wrong. Humans do not understand it very well, but I just dont believe there is a big cosmic conspiracy that created this incredible thing that has nothing to do with the real world.
trying paper tendencies
I have a tendency, more than most other physicists, to try to figure out everything all at once, before I publish. And even to try to figure out everything in my head, without pencil and paper.
differences knowing
There is a difference between knowing what is true and knowing why it is true
