Here’s a thought. Many major cities these days have a science museum or “exploratory” of some kind, like Glasgow’s own Science Centre or Edinburgh’s Dynamic Earth. Why not a museum devoted to mathematics?
Recently there’s been a project launched in London to set up just such a museum: on their website you can find information about what they hope to achieve and how much progress they’re making towards it. Across the Atlantic there’s a similar scheme, based in New York, which seems to be rather closer to completion. I’m not aware of any such museums that currently exist, though of course there are maths-related exhibits in many museums (e.g. at the London Science Museum; or my favourite, Galileo’s middle finger which sits, permanently raised, in a jar in the History of Science museum in Florence). Does anybody reading this know of one? if so, please share!
