During his life, he would present three different solutions to the problem, which asks for an evaluation of the infinite series $\sum_{k=1}^\infty\frac{1}{k^2}$ Since then, people have continually looked for new, interesting, and enlightening approaches to this same problem. Here, we present N different solutions (where N is not to exceed 7 but is no less than 4), drawing from such diverse areas as complex analysis, calculus, probability, and Hilbert space theory. Along the way, we'll give some indication of the problem's intrigue and applicability.Date: Thursday, April 11, 2013Time: 5:30 pmLocation: Wean Hall 8220Submitted by:  Brian Kell
