Non-Scientific questions solved by mathematics I have a general question about the applications of mathematics.
What are some applications of mathematics that are not scientific, perhaps maybe literary or philosophical, or political. 
I am basically asking for the scope of mathematics, and looking for concrete examples. 

As a simple example I would cite the Seven Bridges of Königsberg problem solved by Euler. At that time, Euler was mailed by a politician of the city of Königsberg asking him to help in a problem of finding the "touristically" best walk through some bridges of the city. Euler, at first, argued that such a problem was not a mathematical problem. But the politician insisted writing back to Euler saying that no engineer that was consulted had a conclusive answer. So, after reviewing the problem, Euler realized that the problem was asking for a solution that had nothing to do with geometry (I mean, a solution that is not metric related) as everybody was expecting. At the end, Euler proofed topologically the existence of a solution and gave rise to a new branch of mathematics: topology.
