Calculus
Calculus is for anyone who ever complained that math isn't useful for anything. Calculus is a branch of mathematics that deals with problems involving changing rates. It has universal applications, finding its way into physics, engineering, medicine, economics, and anything that involves something changing. Calculus commands a great deal of notoreity from students learning it. But, like any form of mathematics, it is all pure logic, and if you understand it, it can be a very beautiful thing.
Newton and Leibniz both developed calculus on there own. Inventing calculus; now how fucking brilliant do you have to be to INVENT calculus? Pretty damn fucking brilliant.
