What is Brownian motion?
Q: What is Brownian motion?
A: Brownian motion is the random motion of particles in a liquid or a gas caused by fast-moving atoms or molecules that hit the particles.
Q: Who discovered Brownian Motion?
A: Brownian Motion was discovered in 1827 by the botanist Robert Brown.
Q: How did Albert Einstein contribute to understanding Brownian Motion?
A: In 1905, Albert Einstein published a paper which explained how the motion observed by Robert Brown was caused by individual water molecules hitting the particles. This helped convince many scientists that atoms and molecules exist.
Q: Who verified Einstein's theory experimentally?
A: Jean Perrin verified Einstein's theory experimentally in 1908 and was awarded the Nobel Prize in Physics for his work on matter structure.
Q: How does this random pattern occur?
A: The direction of force from atomic bombardment constantly changes, leading to different sides of the particle being hit at different times and causing seemingly random patterns of movement.
Q: What kind of models are used to describe it? A: Probabilistic models of molecular populations such as those made by Einstein and Smoluchowski, as well as stochastic process models are used to describe it.
Q: Who else studied Brownian Movement with greater mathematical precision? A: Norbert Wiener also studied Brownian Movement with greater mathematical precision.
