The climate simulations were the third-largest use of computing cycles at a leading U.S. supercomputing cluster. The study of quarks and other subatomic particles came in second. Topping the list was the most heavily cited idea in the physical sciences — though few have ever heard of it.
Science’s best-kept secret goes by the name of density functional theory (DFT), and it is the chief method physicists and chemists use to understand just about anything more complicated than a hydrogen atom. For decades, researchers have harnessed DFT’s abilities to predict everything from the taste of coffee to the consistency of Jupiter’s core.
Some researchers now believe Machine Learning could help researchers take larger and faster steps toward a master electron equation that would unlock the secrets of novel drugs, superconductivity and exotic materials.The electrons is to know the atoms, molecules, and materials they make up. Physicists have thoroughly understood electrons since the 1920s when Erwin Schrödinger published his eponymous equation. But when it comes to analyzing throngs of electrons, that understanding has proved all but useless.
