### Resources for Non-Specialists

#### The Mathsters

YouTube channel of short maths videos aimed at sixth formers interested in doing maths at university, and other interested adults.

#### The Maths of Cream Tea

Mathematical proof that clotted cream is better than whipped cream! Note: the papers are reporting that this “research” was commissioned by a clotted cream company. However I was not paid by them, nor did I even receive any clotted cream – and I couldn’t find any in Sheffield so I clotted my own in the rice cooker! Read the full story here.

#### The Maths of Pizza

#### The Maths of Doughnuts

#### The Maths of Mince Pies

#### The Maths of Popping Open a Bottle of Bubbly

**Higher-dimensional category theory**

The architecture of mathematics [**pdf**] – an introduction to my field and my research as of November 2001. Written for non-specialists in any discipline (originally as part of a job application), it is very non-technical and includes various flights of fancy and copious analogies.

#### Mathematics and Lego

The untold story [**pdf**] – approximate text from a seminar I gave at Newnham College in November 2001 aimed at students and researchers of all levels and all disciplines. This is not a formally presented document, and it doesn’t include the slides, so some of it is a bit hard to imagine. Also, a radio interview I did on the subject in December 2012, on BBC Radio 4’s **“More or less”**.

#### Mathematical Morality

A talk I gave at the Cambridge University Society for the Philosophy of Mathematics, and in a modified version later at the University of Chicago
