However, the original version of the segment still survives. This segment was one of two sections in which Benny Goodman and his Orchestra contributed. Their music played over visuals that were drawn by a pencil as the action occurred. The scene portrayed teens
Lune of Hippocrates give the only constructible squarable lunes; in particular, there are no constructible squarable convex lunes. Lune of Hippocrates In geometry, the lune of Hippocrates, named after Hippocrates of Chios, is a lune bounded by arcs of two circles, the smaller of which has as its diameter a chord spanning a right angle on the larger circle. Equivalently, it is a non-convex plane region bounded by one 180-degree circular arc and one 90-degree circular arc. It is the first curved figure to have its exact area calculated mathematically. Hippocrates wanted to solve the classic problem of squaring the circle, i.e. constructing
