He receives the prize for conceiving the IceCube neutrino detector, a cubic-kilometer-sized detecter in the Antarctics.

Mechanism is via conversion of neutrinos into charged particles which are then detected via Cherenkov radiation which is produced when a charged particle moves with speeds larger then the speed of light in the medium. (That is only possible because it is less than the speed of light in vacuum which cannot be exceeded.)

If anyone was wondering how some of that heavy stuff gets to the south pole to build such a large engineering project, at the farthest possible end of any logistics chain:

Significant amounts of things still come in by air cargo at great cost, but a lot also comes the long slow way.

The Telescope in the Ice was a solid book about this.

I read all of that and other resources online and still couldn't understand why the hell we need to build that and especially in south pole antartica
