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 ...

Diffusion is the movement of particles from higher to lower concentrations. Diffusion happens naturally and so does not require energy. Substances like oxygen, carbon dioxide and glucose move in ...

Diffusion is the net movement of molecules from an area where they are at a higher concentration to areas where they are at a lower concentration. This is due to the random movement of the ...
