I managed to fit an algebraic proof of Pythagoras' theorem into a very tiny book. The book is just barely taller than a U.S. nickel.

A promotional image for my 2024 charity sketch sale, featuring various pencil sketch portraits of dinosaurs. The text reads: “ALTERNATE EVENINGS ON BLUESKEY DECEMBER 2ND - 30TH 8PM GMT. ALL PROCEEDS TO MEDECINS SANS FRONTIERES AND EASTERN VALLEY FOODBANK.

A reminder that this begins tomorrow, December 2nd, at 8pm, GMT.

Original dinosaur sketches, for £15 (but you can donate more). All proceeds split 50/50 between MSF (Doctors Without Borders) and the Eastern Valley Foodbank.

Please share and see you tomorrow at 8.

I have purchased a couple dozen very tiny blank books. Now, to condense various subjects to fit... I plan to start with a set of math texts: Algebra, Geometry, Trigonometry, & Calculus.
