Why the hot light bulb annoys me Peter Rowlett 2 nd Maths Jam Conference, Nov 2011

A puzzle There are 3 switches outside a closed room. One of them controls a lightbulb inside. Flip switches as much as you like then open the door and say which switch controls the lightbulb.

Solution Flip A. Wait 10 minutes. Flip A back. Flip B. Open the door. Three options: – Lightbulb is on: it’s B. – Lightbulb is off and cold: it’s C. – Lightbulb is off and hot: it’s A.

Grammar test Which is correct?

Grammar test A: don’t be silly, the yolk of an egg is yellow

A sorites a)babies are illogical b)illogical persons are despised c)no one is despised who can manage a crocodile

A sorites a)babies => illogical b)illogical => despised c)manage a crocodile => not despised or despised => not manage a crocodile A: babies cannot manage crocodiles

For me, saying “don’t be silly, a yolk is yellow” is like saying “of course babies can’t manage crocodiles”

There are 3 switches outside a closed room. One of them controls a lightbulb inside. Flip switches as much as you like then open the door and say which switch controls the lightbulb.
