"Uber die von der molekularkinetischen Theorie der Wärme gefordete Bewegung von in ruhenden Flüssigkeiten suspendierten Teilchen", or "On the Motion—Required by the Molecular Kinetic Theory of Heat—of Small Particles Suspended in Stationary Liquid", was a journal article authored by Albert Einstein and published in Annalen der Physik 17, page 549, in May 1905. It was an important work on the brownian motion of fluids.
Before this paper, atoms were recognized as a useful concept, but physicists and chemists hotly debated whether atoms were real entities. Einstein's statistical discussion of atomic behavior gave experimentalists a way to count atoms by looking through an ordinary microscope. Wilhelm Ostwald, one of the leaders of the anti-atom school, later told Arnold Sommerfeld that he had been converted to a belief in atoms by Einstein's complete explanation of Brownian motion.
