Einstein published 26 papers in 1905: four of them caused Scientific Revolutions

The year 1905 proved extraordinarily productive for Einstein. He was earning some extra income with minor reports about literature. But in this year, heºlight-quanta hypothesis, on Brownian movement, on the electrodynamics of moving bodies, and on the interrelation of mass and energy. He also concluded his doctoral dissertation in this year. In the preceding years, between 1902 and 1904, he had proceeded from Boltzmann’s kinetic gas theory to develop statistical mechanics. On this basis he reinterpreted Brownian molecular movement and recognized that Planck’s formula for the energy distribution of thermal radiation jarred with the conception of waves in a continuous aether. He interpreted Planck’s formula in a new way using atomistic light quanta. To eliminate the need for “aether” in the electrodynamics of moving bodies as well, Einstein ultimately introduced new concepts of space and time.
