Quantum mechanics

Heisenberg and Schrodinger write the laws that govern atoms and light.

Matrix mechanics (1925) and the wave equation (1926), with Born's probability rule and Heisenberg's uncertainty principle (1927), explained chemistry and the solid state. Transistors, lasers and MRI all depend on it.
