Spanish independent publisher Kronecker Wallis is making a new edition of Isaac Newton’s Principia Mathematicia, using a Kickstarter campaign to fund the initial print run. Here’s their video:
It looks like it’ll be a fairly pretty object, and they’ve put a lot of time and thought into choosing the paper, fonts and layout. Their Kickstarter runs for around another 24 hours, and a pledge of €45 or more will secure you a copy of the finished article.
Edmund Harriss is a very good friend of the Aperiodical, and a mathematical artist of quite some renown. His latest project is CURVAHEDRA, a system of bendable boomerang-like pieces which join together to make all sorts of geometrical structures.
I did a little bit of Sloanewhacking and found a couple of sequences containing $25641$ which almost, but don’t quite, describe this property. So, semi-spoiler warning: you might enjoy A256005 and A218857. I’d like to come up with the ‘magic number’ which looks the least like it’ll have this property – any ideas?
I was invited to give a talk for Ustinov College’s Café Scientifique on π Day this year. The turnout wasn’t great and I put quite a bit of effort into the slides, so I wanted to put it online. I’ve finally got hold of the recording, so here it is. Unfortunately they didn’t set the camera’s exposure properly, making the screen illegible, so you’ll probably want to follow along with the slides in another window.
