It was begun with the invention of relativity theory and quantum theory.

It was Einstein's great general theory of relativity.

So this is general relativity, this is quantum theory.

We associate the name of Einstein with the theory of relativity.

And he was reading Einstein's recently published general theory of relativity, and he was thrilled by this theory.

Then Einstein, with his special theory of relativity, looked at a whole set of symmetries of Maxwell's equations, which are called special relativity.

Text In another 30 minutes they would reach the Theory of Relativity. And then?

And not only that, they make the analogy to relativity theory and cosmology often.

This instrument will fly on NASA apos s Gravity Probe B (Relativity) Mission, which is designed to test important aspects of Einstein apos s Theory of General Relativity.

Under extreme conditions, general relativity and quantum theory allow time to behave like another dimension of space.

(d) QUICK STEP verification of the equivalence of the inertial and gravitational mass (theory of relativity) with a relative precision of 10 17.

At the same time, we physicists have been busy trying to make sense of and build on and integrate the discoveries of quantum theory and relativity.

One Hundred Years of Relativity

Their work demonstrated convincingly the appropriateness of general relativity as a theory of gravitation under extreme conditions and indirectly confirmed the existence of the gravitational radiation Albert Einstein had predicted.

Unexpected by researchers, such a force had nevertheless been predicted in 1915 by a modification that Albert Einstein proposed to his own theory of gravity, the general theory of relativity. But he later dropped the modification, known as the cosmological term, calling it the biggest blunder of his life.

I'm thinking of Lorenz contractions and Einsteinian relativity.

This is a year when Einstein is basking in the glow of having discovered the special theory of relativity and decides to take on a new project, to try to understand fully the grand, pervasive force of gravity.

This computer simulation is due to a relativity group at NASA Goddard.

So there is this direct line between feminine handicraft, Euclid and general relativity.

Because they're moving real fast, relativity says the internal motions go very slow.

STOCKHOLM This year marks the centenary of Albert Einstein's general theory of relativity, his masterwork describing gravity as the curvature of space and time. Yet, as is often true in science, Einstein's insights have provided physicists with as many questions as they have answered.

The God theory is not just a bad theory.

M Theory

What theory?

In theory.

A few years ago, I was pretty excited to discover that there are candidate universes with incredibly simple rules that successfully reproduce special relativity, and even general relativity and gravitation, and at least give hints of quantum mechanics.

What's your theory?

What's that theory?

The theory is

That's mere theory.

It was theory.

An interesting theory.

Theory and empirical evidence

There was a theory.

That is the theory.

Well, what's your theory?

Oh, my theory. Well

What's your theory, Colonel?

It's only a theory.

I have a theory.

It's proved in theory.
