The Laplacian and the Heat Equation
The Laplacian measures how much a quantity differs from the value of that quantity on average in a tiny little neighborhood. If you want to know how heat changes in a body that's being warmed up then if you've got a point where it's a little bit colder than the average around it it will tend to warm up at that point. Theheat equation is actually that was mainly Fourier who did that analysis but theLaplacian plays an extremely important role in that analysis I haven't I didn't get any idea I didn't ask so what sort of a man it was I heard late only had two children went off to the country for safety he allowed himself to be called
