He opened his copy of the Bartelmann/Lüst textbook , a staple for students across Germany and Austria. The text spoke of and Harmonic Oscillators . To a classical mind, a swing just goes back and forth. In TP3, that swing was a series of probability densities, a ghost of motion that only "collapsed" into reality when someone bothered to look.

He was currently stuck in a "superposition" of understanding and total confusion. In , the universe had stopped behaving like a collection of billiard balls and started behaving like a complex-valued wave. He opened his copy of the Bartelmann/Lüst textbook

They spent the next four hours battling the , those "bras" and "kets" that turned physical states into vectors in an infinite-dimensional space. By midnight, the coffee was cold, but the math finally started to sing. They weren't just solving for In TP3, that swing was a series of

anymore; they were finding the fundamental frequencies of existence.
