Emergency Maths Arcade (Or, suggestions of pen and paper mathematical games)
Last week we had a crisis at work — we misplaced the key to the Maths Arcade cupboard, in which we store the games (don’t ask!). So I was on the look out for something to do without opening the cupboard — i.e. on pen and paper — and I turned to Twitter for help.…

Well, it’s currently looking for funding on Kickstarter in advance of actually existing, and the first…

Council orders maths & Sudoku to be removed from mathematician’s gravestone
There is a fine tradition of mathematicians with mathematics on their tombstones. What immediately springs to mind is Ludolph Van Ceulen and Jacob Bernoulli. Van Ceulen calculated $\pi$ to 35 decimal places; his grave carried both his lower bound of 3.14159265358979323846264338327950288 and his upper bound of 3.14159265358979323846264338327950289. Bernoulli asked for a logarithmic spiral on his…
Eugenia Cheng is at it again
Dr Eugenia Cheng, category theorist, has accepted some money from Pizza Express in return for writing some nonsense about pizzas. This doesn’t really merit a post here, apart from to point out that Dr Cheng very scrupulously denied taking any kind of payment the last time she got a “formula for the perfect X” story…
