Bank of Somerville: 10 Pound Denomination

Sometimes, strange things happen in our Somerville mathematics presentations --- like seeing currency from the Bank of Somerville with my picture on the 10-pound note and my colleague Quentin Miller's picture on the 20-pound note. (The reason I am on the smaller denomination is probably because I am a cheap date.)

(Thanks to Andrew MacFarlane for drawing these, and thanks to both him and Tim Camfield for an excellent presentation on paradoxes.)
