A cuboid with integer sides and diagonals are special cases of this man's namesake bricks, and he lends his name to a set of polynomials which are related to the Bernoulli numbers. His namesake line connects the circumcenter, orthocenter, and the centroid, and he names a constant whose irrationality is yet to be confirmed, along with Mascheroni. For 10 points, identify this mathematician whose namesake formula relates complex exponents to the sine and cosine functions, and whose namesake number is the base of the natural log.
