    More things to occupy your time after the fold!

  • Puzzle Corner: Help Timothy Spot the Author

    Poor Timothy is still having problems with human faces. I don’t know what fraction of science-fiction authors have beards but I’d guess 30%? Sometimes feels like more! Can you match the beard-style (numbered) to the author (lettered) so Tim can tell which is which?

  • Farewell Raymond Smullyan

    Martin Gardner was a kind of gateway drug. When I was a kid I went to the same secondary school that my dad taught at. That wasn’t a particular problem for me but it meant I had to hand around school until he was heading home. This meant sitting in the school library by myself […]

At io9’s  regular puzzle spot they have a modern (1960s) version by Hubert Phillips. Pickled walnuts are always provided at Professor Piltdown’s parties. No animal that does not prefer Beethoven to Mozart […]

Essentially you just need three things 1. all the numbers in the solution are positive integers (but not […]

    There is a neat puzzle on The Guardian website that has interesting implications for evolution or fictional social policy. The government – which wants to increase the ratio of girls to boys – introduces a law for all couples that states: If a couple has a boy, they have another child. If a couple has […]
