Prof.
Christian Bär is a mathematician at the University of Potsdam, in Germany. He teaches a partial differential equations class and makes his lecture notes available for free download to his students. He asked us to use the image of our
Heat Equation Mug on the lecture notes cover. We agreed, and the the cover looks pretty cool. In case you are curious download the lecture notes,
Partielle Differentialgleichungen, a 1.5 MB PDF file in German. Thanks to Prof. Bär for his interest.
This Nostromics design shows the
heat equation with red, dynamic HOT! text. This partial differential equation of physics
models variations of temperature over time in all places of the universe, including a steaming cup of coffee or tea. See also the
Heat Equation Large Mug in the
Physics section of Nostromics Store.
