Four Colours Suffice

This saw the first meeting of the new term for the Oxford University Invariant Society, and to celebrate the 150th anniversary of the posing of the Four Colour Theorem Next Wednesday we had a talk from the estimable Dr. Robin Williams Wilson (think Richard Whitely with even worse dress sense and puns) on the history and solving of said problem.

Oh, and Robin was also plugging a new book (seems to be a running theme...) link to Amazon to your right.

Attendance was easily the best I've seen in along time although the number of new members was disappointingly low.

Robin has a launch party for his book at Gresham College, London on Monday night. I can guarantee which shirt he'll be wearing.

The flyer for the book says something along the lines of 'If you enjoy puzzles, you'll love this!' If only Chris hadn't disclaimed birthday presents...
