Описание к видео George Hart - Abraham Sharp and the "Sharpohedron" - G4G15 February 2024

The British scientific instrument maker Abraham Sharp (1653–1742) is known for his calculation (circa 1700) of Pi to 72 decimal digits. But a greater accomplishment was his 1717 book Geometry Improv’d with detailed mathematical calculations, handmade copperplate engravings, and practical instructions explaining how to slice twelve original polyhedra from solid blocks of wood.
