Contrast

Son Goku

As a visual comparison I thought I'd post up the two greatest equations in physics.

The first equation describes gravity:


The second equation describes all kinds of matter and the three other fundamental forces:
Standard Model Lagrangian.

And people wonder what the appeal of super string theory is!

Don't worry, you'll never have to do calculations with it unless you go into HEP theory, and even then it's likely you'd only use the full Hamiltonian for simulations.

D'Oh! Just noticed it was the Lagrangian and not the Hamiltonain that Son Goku posted. Well, the same applies.

Interesting, I don't think I've ever seen such a long equation. Its quite daunting!

Hey, when I stare at that for a few mins I can see an apple falling from a tree! Do you?

So you're saying the standard model predicts gravity?

needless to say I don't see Zanket here

What I love is the contrast between how one is the result of pure thought, an achievement in reason. Where as the other is an achievement of pure phenomenology, i.e. "let's model this phenomenon".

Yes it is quite a contrast. It certainly motivates looking into supersymmetry

Where is the freakin = sign?!

Son Goku

It's implicit. Basically it's L = (the whole thing). Where L is the Lagrangian.
