‘Machine Scientists’ Distill the Laws of Physics From Raw Data
Researchers say we’re on the cusp of “GoPro physics,” where a camera can point at an event and an algorithm can identify the underlying physics equation.
Hasnain says:
“In February, they fed their system 30 years’ worth of real positions of the solar system’s planets and moons in the sky. The algorithm skipped Kepler’s laws altogether, directly inferring Newton’s law of gravitation and the masses of the planets and moons to boot. Other groups have recently used PySR to discover equations describing features of particle collisions, an approximation of the volume of a knot, and the way clouds of dark matter sculpt the galaxies at their centers.
Of the growing band of machine scientists (another notable example is “AI Feynman,” created by Max Tegmark and Silviu-Marian Udrescu, physicists at the Massachusetts Institute of Technology), human researchers say the more the merrier. “We really need all these techniques,” Kutz said. “There’s not a single one that’s a magic bullet.””
