Talk
Speaker: Prof. David Tong
Title: The Quantum Hall Effect
Abstract: Take a bunch of electrons, restrict them to move in a plane, and turn on a magnetic field. This gives rise to some of the most beautiful and surprising results in physics. I’ll give an overview of this subject and describe the deep connections with the mathematics of topology and knots.

The talk will take place at 8:30PM on Monday 10 October in the Winstanley Lecture Theatre (Map http://map.cam.ac.uk/Winstanley+Lecture+Theatre#52.207035,0.119397,17). As usual there will be free port and juice served before the talk at 8:15PM. This talk is for members only, but there will be a chance to sign up for TMS life membership for £2.50.

Correction
The talk by Prof. Béla Bollobás will be held at 7PM on Friday 14 October in the Centre for Mathematical Sciences. This has been misprinted on some of the term cards.

Puzzle Hunt
In Lent term the TMS and the TCSS will organise a joint puzzle hunt. There will be a broad spectrum of puzzle styles ranging from cryptic, picture, word, logic and a whole lot more. The aim of each puzzle is to reveal a hidden word – it is up to you to figure out how.

This term we will release weekly taster puzzles. You can find our first puzzle on here or the back of your term card. Write your name, answer and reasoning on a piece of paper and hand it in at the talk. We will draw a winner.
