John Faben Who can name the Biggest Number?
Inspired by Scott Aaronson's essay "Who can name the Bigger Number?", we begin the talk with a game - everyone was given 30 seconds and a piece of paper, and asked to write down the biggest number they could. The discussion proceeded to an attempt to discuss some real-life big numbers - the number of cigarettes smoked in the world in a year, the number of letters in the university library, the number of seconds in a human lifetime, the number of elementary particles in the observable universe, etc.

We then went on to discuss some really big numbers - we defined Knuth's Up Arrow Notation, and made an attempt to understand quite how big Graham's number really is. Then we moved onto *really* big numbers. After a (brief) discussion of Turing Machines and the Halting Problem we defined the Busy Beaver, and the Busy Beaver shift function, which provably grows faster than any computable function.

Andrew Curtis Something about Formalism
In its most austere form formalism is the philosophical doctrine that mathematics consists solely in the activity of manipulating strings of symbols by certain stipulated rules. This talk will be an overview of the topic, highlighting some of the theory's strengths and weaknesses.
