This article traces the origin of the Greek fraternity (and sorority) in US universities.
Contrary to popular belief, the first fraternities were formed as a way to assist those struggling in physics. It was discovered that at prestigious universities around the world, students were having difficulty not with the mathematics behind physics, but with the memorization of all the Greek letters. Students could not keep their omegas and thetas separate until one day, two identical twins known only as “the brothers” organized a house in which they could practice physics.
Could it be that not only can physicists take credit for the World Wide Web, but also all those fraternities and sororities across the US? Say it isn't so, Porky!
