The exponential, Riemann's zeta, the Weierstrass : every now and again a function comes along that is just Special, there's no real expaination for it- it just is. Sometimes they see fit to generalize, sometimes to link- sometimes they just seem to frame a problem just right... but a little playing usually reveals that you are getting rather more than you bargained for.

The gamma is one such function. Jam packed with more features than you can shake a stick at, it fascinated Euler and is a fundamental building block of almost anything interesting in complex analysis. It also happens to be Dave McCormick (of revision guide fame)'s favourite.

Come join the fun for another breath of fresh mathematical air so interesting you can scarcely keep your trousers on. Maths. Banter. Grad. Awesome.
