‎3 diagrams 1956 unabridged and unaltered republication (1st translation in English was 1926) "Contents, Chapitres : Preface, Contents, vii, Text, 122 pages - On the movement of small particles suspended in a stationary liquid demanded by the molecular-kinetic theory of heat - On the theory of the Brownian movement - A new determination of molecular dimensions - Theoretical observations on the Brownian motion - Elementary theory of the Brownian motion - Notes and index - This motion is named after the botanist Robert Brown, who first described the phenomenon in 1827, while looking through a microscope at pollen of the plant Clarkia pulchella immersed in water. In 1905, almost eighty years later, theoretical physicist Albert Einstein published a paper where he modeled the motion of the pollen particles as being moved by individual water molecules, making one of his first major scientific contributions. This explanation of Brownian motion served as convincing evidence that atoms and molecules exist and was further verified experimentally by Jean Perrin in 1908. Perrin was awarded the Nobel Prize in Physics in 1926 ""for his work on the discontinuous structure of matter"". The direction of the force of atomic bombardment is constantly changing, and at different times the particle is hit more on one side than another, leading to the seemingly random nature of the motion.
