This mathematician names honeycombs and tessellations that use regular and semi-regular shapes to fill a space.
This mathematician names honeycombs and tessellations that use regular and semi-regular shapes to fill a space. Shapes named after Catalan are the duals of the thirteen shapes named after this man, which includes the snub dodecahedron and the rhombicuboctahedron. This man names a property of the real numbers which states that for any real number x, there exists a natural number n greater than x. He tried to calculate how many grains of sand could fill the universe using a "myriad" counting system in his book The Sand Reckoner. He also devised a method for calculating the area under a parabola using the method of exhaustion. The formula "r equals a plus b theta" in polar coordinates generates his spiral. For 10 points, name this mathematician who also names a principle stating that the weight displaced by a body in a fluid is equal to the buoyant force on it.
