To his left, a "conventional system" of electrons moved in an orderly, predictable dance, like commuters in a train station. But as he turned the page, the "Strongly Correlated Matter" took over. Here, the electrons were no longer individuals. They were a mosh pit, a tangled web where one particle's movement sent a violent ripple through every other soul in the room.

Arthur looked down at the book. The equations on the page were no longer terrifying squiggles of Greek letters; they were the sheet music for the light hitting the windows and the blood pumping in his veins. A Course in Quantum Many-Body Theory: From Conv...

Arthur, a third-year PhD student whose eyes were permanently bloodshot from staring at Feynman diagrams, pulled it down. He didn’t notice the dust that puffed out, nor did he notice that the book felt inexplicably heavy, as if it contained a small, dense star. To his left, a "conventional system" of electrons
