Temperature Waves - done! Watercolor on watercolor paper, glued to a stretched canvas and varnished! Heat equation, definition of diffusity, and temperature distribution in the four seasons (Northern hemisphere). #Physics #SciArt #MathArt

Watercolor painting of the temperature distribution beneath the surface of the earth. Based on the assumption that the temperature varies sinusoially at the surface. Also showing the heat equation and the definition of thermal diffusivity. Four different curves for different times of the year (seasons) - indicated by zodiac symbols. By elkement 2026.

Close-up of my watercolor painting glued to a stretched canvas and varnished - satin finish, the photo shows the sheen.

Detail of my varnished watercolor painting - formula for the definition of thermal diffusivity, in symbols of gradually varying colors.
