Brownian motion refers to the erratic and random movement of microscopic ... in 1827 and is a classic example of diffusion at the microscopic level. The Stokes-Einstein equation provides a ...

Video capture: The laser illuminates the sample, and the camera records a video of the nanoparticles' Brownian motion ... Using the Stokes-Einstein equation, the particle size is calculated from the ...

In this paper, Prof. Perrin gave a detailed account of his work upon the distribution in fluids of small particles, which show the Brownian movement, and the bearing of these results on the ...

The discovery that these two apparently unrelated branches of physics are in some sense mathematically equivalent has led to a new subject known as probabilistic ...
