Brownian motion is the random motion of particles suspended in a medium ... the discovery of this phenomenon is often credited to the botanist Robert Brown in 1827.
Robert Brown was born in Montrose, Scotland on 21 December 1773, in a house that existed on the site where Montrose Library currently stands. He was the son of James Brown, a minister in the Scottish Episcopal Church with Jacobite convictions so strong that in 1788 he defied his church's decision to give allegiance to George III.
In mathematics, the Wiener process (or Brownian motion, due to its historical connection with the physical process of the same name) is a real-valued continuous-time stochastic process discovered by Norbert Wiener. [1] [2] It is one of the best known Lévy processes (càdlàg stochastic processes with stationary independent increments).
The second paper explained Brownian motion, which established the Einstein relation = and compelled physicists to accept the existence of atoms. The third paper introduced Einstein's special theory of relativity , which proclaims the constancy of the speed of light c {\displaystyle c} and derives the Lorentz transformations .
Brownian motion In 1827, the British botanist Robert Brown observed that dust particles inside pollen grains floating in water constantly jiggled about for no apparent reason. In 1905, Einstein theorized that this Brownian motion was caused by the water molecules continuously knocking the grains about, and developed a mathematical model to ...
Jean Baptiste Perrin ForMemRS [1] (30 September 1870 – 17 April 1942) was a French physicist who, in his studies of the Brownian motion of minute particles suspended in liquids (sedimentation equilibrium), verified Albert Einstein's explanation of this phenomenon and thereby confirmed the atomic nature of matter.
The term "Brownian motor" was originally invented by Swiss theoretical physicist Peter Hänggi in 1995. [3] The Brownian motor, like the phenomenon of Brownian motion that underpinned its underlying theory, was also named after 19th century Scottish botanist Robert Brown, who, while looking through a microscope at pollen of the plant Clarkia pulchella immersed in water, famously described the ...
Louis Jean-Baptiste Alphonse Bachelier (French:; 11 March 1870 – 28 April 1946) [1] was a French mathematician at the turn of the 20th century. He is credited with being the first person to model the stochastic process now called Brownian motion, as part of his doctoral thesis The Theory of Speculation (Théorie de la spéculation, defended in 1900).
