just finished The Music Of The Primes (after being lent it years ago by a friend 😬) and was pumped to learn that one of my fave lecturers from my undergrad was thanked in the acknowledgements! it's a small maths world

"One very common question that comes up at the end of a lecture is, “Does all this have any practical applications?” It’s really intriguing because this question is asked in almost exactly the same words wherever I go. It’s like listening to a prerecorded message."

"I don’t know about other people, but I have a practical application for my toys. When I show my toys to some children, they seem to be happy. If that’s not a practical application, what is?"


“The question is in its present form, do all aspects of it enjoy my approval? And the answer is no.” - Langlands on the Langlands Program (lol) thewalrus.ca/the-greatest-math

Logging on to Mastodon via scholar dot social where it's a bit of a gamble what "latex" in the CW could be referring to

on sphere packing: "Everybody asks what is special about dimensions 8 and 24 — I don't know, it's a mystery" plus.maths.org/content/packing

going back to my alma mater today to persuade maths students to not just become accountants 👀✊

I have finally completed a Crossnumber from @chalkdustmag without finding a fatal flaw on the way! feeling v proud of myself

Here's a fun TIL: Because the ratio of terms in the Fibonacci sequence approaches phi, and because phi is close to the ratio of km to miles, you can approximate conversion between distances with adjacent Fibonacci numbers.

So 2 km ≈ 1 mile, 3 km ≈ 2 miles, 5 km ≈ 3 miles, 8 km ≈ 5 miles, 13 km ≈ 8 miles, etc, etc

not feeling anyone I follow talk about the "proof" at , which obviously bodes not well! scepticism abounds in the Reddit/MathOverflow threads linked to from aperiodical.com/2018/09/atiyah

Anyway, here's what I've made today: factorisation-list.glitch.me
A never-ending list of factorisations. Turns out that you can't scroll faster than the absolutely most naive algorithm imaginable can keep up with.
