What has any poet to trust more than the feel of the thing? Theory concerns him only until he picks up his pen, and it begins to concern him again as soon as he lays it down.

I've got a theory that if you give 100% all of the time, somehow things will work out in the end.

I have just got a new theory of eternity.

Time travel and teleportation will have to wait. It may take centuries to master these technology. But within the coming decades, we will understand dark matter, perhaps test string theory, find planets which can harbor life, and maybe have Brain 2.0, i.e. our consciousness on a disk which will survive even after we die.

I was a teacher for a long time. I taught at a community college: voice, theory, humanities. And nowadays, music education is a dying thing. Funding is being cut more and more and more.

A professor must have a theory as a dog must have fleas.

I have a theory because I was being beaten up a lot by people outside of school, it was almost like if I could make myself sick enough they'd take sympathy on me.

Success is not a matter of mastering subtle, sophisticated theory but rather of embracing common sense with uncommon levels of discipline and persistence.

I have a theory and I really believe it. I think your worst weakness can become your greatest single strength.

Every great batter works on the theory that the pitcher is more afraid of him than he is of the pitcher.

String theory envisions a multiverse in which our universe is one slice of bread in a big cosmic loaf. The other slices would be displaced from ours in some extra dimension of space.

I've always been interested in the idea of space exploration. When I was younger it was just a dream, but the theory of rockets being able to travel through space was very much alive. I found it very exciting.

Einstein's gravitational theory, which is said to be the greatest single achievement of theoretical physics, resulted in beautiful relations connecting gravitational phenomena with the geometry of space; this was an exciting idea.

I have a theory that women are generally given space and appointed to jobs when the situation is tough. I've observed that in many instances. In times of crisis, women eventually are called upon to sort out the mess, face the difficult issues and be completely focused on restoring the situation.

We have never observed infinity in nature. Whenever you have infinities in a theory, that's where the theory fails as a description of nature. And if space was born in the Big Bang, yet is infinite now, we are forced to believe that it's instantaneously, infinitely big. It seems absurd.

According to String Theory, what appears to be empty space is actually a tumultuous ocean of strings vibrating at the precise frequencies that create the 4 dimensions you and I call height, width, depth and time.

So much of the language that surrounds us - from things like economics, management theory, and the algorithms built into computer systems - appears to be objective and neutral. But in fact, it is loaded with powerful, and very debatable, political assumptions about how society should work and what human beings are really like.

Internationalism is a social and political theory, a certain concept of how human society ought to be organized, and in particular a concept of how the nations ought to organize their mutual relations.

My theory is, if you force yourself to smile enough, then you start to feel it. Which comes in handy all the time.

I think I've always had a certain amount of skepticism of this whole 'shut up and smile' theory. I haven't ever swallowed that pill so easily, although I tried.

For years, my early work with Roger Penrose seemed to be a disaster for science. It showed that the universe must have begun with a singularity, if Einstein's general theory of relativity is correct. That appeared to indicate that science could not predict how the universe would begin.

The end of science is not to prove a theory, but to improve mankind.

Science doesn't work by voting. Did people vote on the theory of relativity? No! It's either right or it's wrong. Do we vote on whether genetics is a good theory or not? Of course not.

Science ignores the spiritual realm because it is not amenable to scientific analysis. As importantly, the predictive success of Newtonian theory, emphasizing the primacy of a physical Universe, made the existence of spirit and God an extraneous hypothesis that offered no explanatory principles needed by science.
