The Heat Equation - Rose
... This is the PDE that ρ must obey and is call the “heat equation”. It’s easy (use ρ = c0 + c1 u)) to see that the temperature u obeys the same equation. We’ll usually work in terms of the temperature u, since it’s a more familiar quantity. There’s another situation in which the heat equation frequent ...

Temperature Coefficient of Resistance
... In this paper, I derive a mathematical model for the behavior of a metallic conductor’s resistance, as well as an explanation of the mechanism which affects its dynamics, and a discussion of perhaps why quantum mechanics has designed it to behave as such. The temperature dependent behavior of the re ...
