#Thisweeksfiddler from @xaqwg.bsky.social asked: if you're randomly situated on a semicircular island, what is your expected distance from the coast? After a lot of geometry, calculus and algebra (plus a bit of help from WolframAlpha) I got a surprisingly simple answer. tinyurl.com/fiddler140325

The fun of recreational maths is working out how to answer a question you don't need an answer to! #thisweeksfiddler by @xaqwg.bsky.social persuaded me to spend my weekend working out ways to fold polygons. I think I got the answers right, but there's probably a smarter method... bit.ly/3Ol3Pyu
