Archimedes is the last of the three greatest mathematicians in history. He was known for developing the lever concept, inventing the screw pump, ratios of volumes between spheres and cylinders. There is a myth that he had run through the streets screaming “Eureka!” when he discovered a method of determining gold from fake gold. A soldier killed him during the war; the cause of this dispute is unknown; either the soldier had stepped on his work on the ground and angered him, or he refused to go with the soldier to finish the solution to his math problem. He also liked doing math everywhere; if there were soot nearby, he’d write in it.
Becca Hirsbrunner photographed this fabulously constructed Z proportions letter. Interestingly, every element but the diagonal bar can be rationalized.
