Here are two food books I want to read at some point. Or maybe I'll start with one of them.
Food Matters: A Guide to Conscious Eating, Mark Bittman
The Omnivore's Dilemma, Michael Pollan
Here are some maths books I want to read at some point. They are taken from a list that is given to incoming Oxford maths undergraduates as things they could choose from to read over the summer before they enter the university.
The Music of the Primes, Marcus Du Sautoy
How to Solve It, George Polya
The Man Who Loved Only Numbers, Paul Hoffman (the story of Paul Erdos, which I think might be in the flat somewhere)
1089 and All That: A Journey into Mathematics, David Acheson
