Adding up Feynman diagrams to make predictions about real materials

Caltech scientists have found a fast and efficient way to add up large numbers of Feynman diagrams, the simple drawings physicists use to represent particle interactions. The new method has already enabled the researchers to solve a longstanding problem in the materials science and physics worlds known as the polaron problem, giving scientists and engineers a way to predict how electrons will flow in certain materials, both conventional and quantum.

Using the "real" 4K USB camera rather than my smartphone gets a better image of the electron beam hitting the screen. #physics #accelerators
I should have posted an actual 4K image not the 1080p scaled one, but my computer can only process uncompressed 4K at about 5fps, so I was using 1080p for viewing it continuously.
