Description: Rendered on a deep dark background, this artwork presents how Thales measured the Great Pyramid with a stick and its shadow: two similar triangles labeled H, h, L and l, and the proportion H/h = L/l. Thales of Miletus (c. 624–546 BC) is said to have measured the height of the Great Pyramid by comparing its shadow with the shadow of a stick. The idea rests on similar triangles and the intercept theorem. Made for math teachers, mathematicians and students who love an elegant proof, it brings classic mathematics to a classroom, study or home office.
