Euler's Method was devised by Swiss mathematician, Leonhard Euler. It is a rudimentary method for solving differential equations. There are lot of better ways to solve differential equations, such as Runge-Kutta integration, but they don t really fit the Possessive-Noun format of the (admittedly better) names of the other Warriors.

And please note, Euler is pronounced Oiler. Like the old Houston football team.
