Most Beautiful Theories in Math & Physics

[arpon]

What's the most beautiful theory in Physics or Math you have ever read?
For me, they are the Prime Number Theorem and the Theory of Relativity.

I don't know enough about any particular theory to consider one more beautiful than the next, but I've read enough about relativity, so that is my choice.

For me, they are the Prime Number Theorem and the Theory of Relativity.

There is a difference between "theory" and "theorem", at least in mathematics. Also, the term "theory" seems to have quite a different meaning depending on whether you ask a physical scientist or a mathematician.

Evolution. I find the idea that all life on Earth is connected far more spiritual than any dogma.

math: limit
physics: general relativity
biology: evolution

I guess it's not a theory, but I recall that as I started learning about things in general, that the concept of closed-loop feedback just struck me as a 'beautiful' concept. I just found it fascinating that if you had reference to follow, it could be done with extreme accuracy, or new frequencies generated from a ref frequency, even with very loose tolerance parts. It's magic!
