Mathematical Art and Play Seminars
⌊ n!/e ⌉
This seminar will be given by David Butler as part of the School of Mathematical Sciences Undergraduate Seminar Series in September 2014.
Date: Tue 9 Sep 2014
Time: 2:10 pm
Place: Inkgarni Wardli 715 Conference Room
What is this formula? Why does it use those strangely mismatched brackets, and why does it use both factorial and the number e? What is it supposed to calculate? And why would someone love it so much that they put it on a t-shirt? In this seminar you will find out the answers to all of these questions, and also find out what derangements have to do with Taylor's theorem.

Eigenvalue Magic Tricks
This seminar was given by David Butler as part of the School of Mathematical Sciences Undergraduate Seminar Series in August 2013.
Eigenvalues are awesome, but students rarely get the chance to see just how supremely awesome they are. In this talk I’ll tell you some awesome truths about eigenvalues that you don’t get to see in first year, and show you their proofs, which happen to contain some of the most clever magic tricks in the whole of maths.
