In theory, no prime number is not a theory.

We need a higher theory, and that's where string theory comes in.

Using Galois theory, certain problems in field theory can be reduced to group theory, which is in some sense simpler and better understood.

A delightful theory. A dangerous theory.

In theory, there is no difference between theory and practice. But, in practice, there is.

In theory, there is no difference between theory and practice. But, in practice, there is.

Their theory is called BET theory, after the initials in their last names.

And that theory, we think, is String Theory.

Conformal field theory has important applications in string theory, statistical mechanics, and condensed matter physics.

Motivation from ergodic theory Some of the theory developed by Alain Connes to handle noncommutative geometry at a technical level has roots in older attempts, in particular in ergodic theory.

The God theory is not just a bad theory.

Number theory is the theory of the positive integers.

The God theory is not just a bad theory.

String theory, we think, is a theory of everything.

In physics, matrix string theory is a set of equations that describe superstring theory in a non perturbative framework.

They have applications in many areas of mathematics, including Galois theory, invariant theory, group theory, combinatorics, as well as further applications outside mathematics, including general relativity.

It's impossible in theory, but possible in practice.

My theory?

What theory?

In the context of explaining price, the marginal utility theory is not a normative theory of value.

Is this proposition true? Is this theory a good theory?

China s New Reforms in Theory and Practice

In theory, we're thinking, rational human beings.

It's pretty cool, at least in theory.

In theory, one activity offsets the other.

It is called the theory of general relativity, but in fact it is specifically a theory of gravitation.

The first development of set theory was a naive set theory.

And deterrence theory is a very simple theory of human behavior

Value pluralism is a theory in metaethics, rather than a theory of normative ethics, or a set of values in itself.

Since string theory is the theory of everything, it's also a theory of time, and time machines are allowed in Einstein's equations, but to build one is extremely difficult.

NIST's report on the collapse of the WTC towers rejected the theory in favor of the column failure theory.

A binary erasure channel (or BEC) is a common communications channel model used in coding theory and information theory.

What's that theory?

That's mere theory.

We can actually see this in string theory.
