You may have heard of Brownian Motion already, or even recollect an enthusiastic science teacher demonstrating it and then trying to impart its significance? Brownian Motion was first observed and named, unsurprisingly, after botanist Robert Brown in 1827 and then explained by Albert Einstein in 1905. It provides crucial evidence for the existence of atoms and molecular movement in a medium (liquid or gas). The movement of observed suspended particles is continuous, irregular and influenced by temperature.
