This man who names a line passing through the orthocenter, circumcenter, and centroid of a triangle has a namesake constant that is approximately 2.718.
With Bernoulli, this mathematician developed the classical theory of beams, and he names the fundamental equation of the calculus of variations with Lagrange. This mathematician's namesake characteristic is used to classify topological spaces. He names a function defined as the number of positive integers less than or equal to n that are coprime to n; that is his (*) totient or phi function.
