A brief account of developments in the experimental and theoretical investigations of Brownian motion is presented. Interestingly,
Einstein who did not like God’s game of playing dice for electrons in an atom himself put forward a theory of Brownian movement
allowing God to play the dice. The vital role played by his random walk model in the evolution of non-equilibrium statistical
mechanics and multitude of its applications is highlighted. Also included are the basics of Langevin’s theory for Brownian
motion.
Shama Sharma is currently working as lecturer at DAV College, Punjab. She is working on some problems in nonequilibrium statistical
mechanics.

The important role played by some thought experiments in the development of physics has been brought out by expatiating Maxwell’s demon, time dilation, length contraction, twin paradox, Heisenberg’s microscope and Einstein–Bohr box. 相似文献
