One of the most pervasive processes that serves as the reference time scale for all other processes in cells is that of diffusion. Molecules are engaged in an incessant, chaotic dance, as characterized in detail by the botanist Robert Brown in his paper with the impressive title “A Brief Account of Microscopical Observations Made in the Months of June, July, and August, , On the. A thematic map is used to display spatial diffusion. It is a type of map that focuses on a specific theme or subject area, such as the distribution of geographic areas in a specified region.
