The triangular design on the back reminds me of a Sierpinski triangle – A triangle with a triangle in the center removed, and where each remaining triangle has a triangle in the center removed, and where each of those triangles formed has a triangle in the center removed, ad infinitum (literally). The same thing can be done with a square or cube (a Menger sponge).

Ackoffbay, I’myay ayay ientistsay.
As for equations,
you could tryMaxwell’s equations or Euler’s identity
I have to have a colleague explain Maxwell’s Equations to me in small words. But I think they’re going on the coat. Euler’s Identity is perfect! The idea of finding wonder and beauty in mathematics is very SoE.
