PHYSICS: Derivation of the standard model of particle physics
When I took a course in theoretical high energy physics at university, the professor wrote down the Lagrangian of the standard model, mentioning that that is the current world formula, as it
describes everything we know of in physics at the moment (back in 1993 at least), except for gravity. The formula is not quite enlighting, being a collection of many summands.
Now Alain Connes has derived this Lagrangian from geometric principles (noncommutative geometry, spectral triples), which I find extremely remarkable. Even better, it even contains gravity (in the form of the Einstein Hilbert term).
Here is a very impressive audio representation of his findings (although no transparencies are available, it is still worth listening to get the idea):
Noncommutative geometry and the standard model with neutrino mixing
And here is the result which is supposed to describe all known physics (plus the Higgs particle):
More can be found in the following paper:
Noncommutative Geometry and the standard model with neutrino mixing
Or more explicitely here:
Gravity and the standard model with neutrino mixing
