If ρ(x,t) is the density of Brownian particles at point x at time t, then ρ satisfies the diffusion equation:
where D is the mass diffusivity.

This blog is partly devoted to the sharing of my learning of the English language (my well mastered mother tongue is Chinese and I am not an English teacher) and its *cultures*, partly to the current significant trends in Canada and in the world, and partly to my own random thoughts and little life. I am not religious, but I am somewhat interested in Christianity and Buddhism, among other personal interests. Welcome. And, have a good day.
