Christmas party song requests
On coming back to the School of Mathematics in Edinburgh in the New Year, I was amused by the blackboard in the common room. Christmas party songs had been written on the board during our end-of-year party, but in January, rather than rubbing them off to make space for mathematics, people had just decided to write their maths in the gaps between words. One of our postgraduates, Hari Sriskantha, noted that mathematics is like a weed that grows in unwanted parts of blackboards.
Do you have examples of this happening on your public blackboards too? If so, send them in!
