Definition of Relativity

Relativity Quotations

When you are courting a nice girl an hour seems like a second. When you sit on a red-hot cinder a second seems like an hour. That's relativity.
Albert Einstein

It is probably safe to say that all the changes of factual knowledge which have led to the relativity theory, resulting in a very great theoretical development, are completely trivial from any point of view except their relevance to the structure of a theoretical system.
Talcott Parsons

No matter how hard you try to teach your cat general relativity, you're going to fail.
Brian Greene

Quantum Mechanics and General Relativity are both accepted as scientific fact even though they're mutually exclusive. Albert Einstein spent the second half of his life searching for a unifying truth that would reconcile the two.
Roy H. Williams

In Einstein's general relativity the structure of space can change but not its topology. Topology is the property of something that doesn't change when you bend it or stretch it as long as you don't break anything.
Edward Witten

And it really began with Einstein. We attended his lectures. Now the theory of relativity remained - and still remains - only a theory. It has not been proven. But it suggested a completely different picture of the physical world.
Douglas Sirk

At some point we must realize that actively defending against radical Islamic teachings is not a matter of cultural relativity. It is a matter of universally recognized human rights.
Armstrong Williams

Einstein was searching for String Theory. It not only reconciles General Relativity to Quantum Mechanics, but it reconciles Science and the Bible as well.
Roy H. Williams

In relativity, movement is continuous, causally determinate and well defined, while in quantum mechanics it is discontinuous, not causally determinate and not well defined.
David Bohm

So what I'm saying is why don't we think about changing Schrodinger's equation at some level when masses become too big at the level that you might have to worry about Einstein's general relativity.
Roger Penrose
