This process' namesake PDE has the Gaussian Kernel as a solution.
This process' namesake PDE has the Gaussian Kernel as a solution. The fractional anisotropy iscalculated from the eigenvalues of a tensor named for this process. One quantity describing thisprocess is equal to terminal drift velocity times Boltzmann's constant times temperature. The secondderivative of phi with respect to x is proportional to the first derivative of phi with respect to timeaccording to one law governing it. Another law governing this process says that (*) flux is proportionalto the negative grad of the concentration; those laws are named for Fick. This process occurs through asemipermeable membrane in osmosis. For 10 points, name this phenomenon in which a substance movesfrom an area of high concentration to low concentration.
