| Descrive |
A black and white rendition of my own photograph of the Yale Babylonian Collection's Tablet YBC 7289 (c. 1800–1600 BCE), showing a Babylonian approximation to the square root of 2 (1 24 51 10 w: sexagesimal) in the context of Pythagoras' Theorem for an isosceles triangle. The tablet also gives an example where one side of the square is 30, and the resulting diagonal is 42 25 35 or 42.4263888...(30 x square root of 2). All use should attribute both me (mentioning http://www.math.ubc.ca/~cass/Euclid/ybc/ybc.html) and the Yale Babylonian Collection as the original holder of the tablet.
