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

In chemistry, valence bond (VB) theory is one of two basic theories, along with molecular orbital (MO) theory, that were developed to use the methods of quantum mechanics to explain chemical bonding.

They had a notion, a Platonic notion, of what tomato sauce was.

The theory of plate tectonics explains all this, including the movement of the continents, better than Wegener's theory.

Some of the motivating examples included the Riemann Roch theorem and its generalization the Hirzebruch Riemann Roch theorem, and the Hirzebruch signature theorem.

I'm a biologist, and the central theorem of our subject the theory of design, Darwin's theory of evolution by natural selection.

Dual coding theory, a theory of cognition, was hypothesized by Allan Paivio of the University of Western Ontario in 1971.

There is a theory of group actions on R trees, known as the Rips machine, which is part of geometric group theory.

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

It's only a theory.

Social Learning Theory .

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

Number theory is the theory of the positive integers.

This is a model (natural selection) of the theory of evolution.

In mathematics, the theory of equations is a part of algebra.

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

In mathematics, percolation theory describes the behavior of connected clusters in a random graph.

These theories map well from the underconnectivity theory of autism.

He is responsible for a great body of work in group theory.

Didactics is a theory of teaching, and in a wider sense, a theory and practical application of teaching and learning.

Yet the assumptions that quantum theory needs to make in order to deliver those predictions are so mysterious that even Feynman himself was moved to remark, If you think you understand quantum theory, you don't understand quantum theory.

The theory posits that a small minority, consisting of members of the economic elite and policy planning networks, holds the most power and that this power is independent of a state's democratic elections process.

In fact, there is a new theory of autism called the intense world theory, which suggests that the neocortical columns are super columns.

Beijerinck maintained that viruses were liquid in nature, a theory later discredited by Wendell Stanley, who proved they were particulate.

However, because the standard model is not mathematically self consistent under certain conditions (e.g., at very high energies, at which both quantum mechanics and general relativity are relevant), physicists believe that it is underlaid by some other theory, such as a grand unified theory, string theory, or loop quantum gravity.

He said, Yeah, it's an amazing theory.

So what will brain theory look like?

The God theory is not just a bad theory.

Evolutionary Theory s Welcome Crisis

A Moral Theory s Immoral Outcome

Call it the porcupine theory.

Set theory is a branch of logic and not technically a branch of algebra.

In theoretical physics, type II string theory is a unified term that includes both type IIA strings and type IIB strings theories.

A related theory deals with the quality of connections, rather than their existence.

Epistemology branches off from philosophy and deals with the origin of knowledge.

Many problems in communication theory can be reduced to a BEC.

First of all, it's going to be a theory about memory.

They are removing evolution theory class.
