(Simons Foundation)   The physicists amongst you will find this article pretty amazing. For the rest of us, just be content that the term "Grassmanian" is considered as acceptable jargon in physics   (simonsfoundation.org) divider line 15

It's a perfectly Larsonian word.

Again? How about Repeatarian? Is that a word?

It's not a repeat. It's just time folding in upon itself.

Those twistor diagrams look Gallifreyan...

Better luck last time, Intelligent_Donkey.

Precision Boobery: Better luck last time, Intelligent_Donkey.


I steal all of my good posts from TFers who live in the future.

What's kind of amusing about this article is that Feynman diagrams are themselves vastly faster graphical ways for computing terms in quantum electrodynamics.  They condensed pages of tedious integrals to a couple of scribbles.  Julian Schwinger, one of the other winners of the Nobel prize for QED once commented "Like the silicon chips of more recent years, the Feynman diagram was bringing computation to the masses."

It's as though time were geometric, perhaps cube-shaped...

So, the amplituhedron  is a space-time pixel?

Our son was home from grad school this weekend, and this discovery was the first thing he told us about. He said the whole department was excitedly plugging these new equations into their research projects.

His prof's research involves modeling a Helium-4 nucleus as a cloud of interacting quarks, rather than as two protons and two neutrons. So at three quarks per particle, it's a 12-body physics problem. I can see why they'd be excited by  anything that promised to simplify the math!
