Knitted Spiky Icosahedron
As an avid knitter, and mathematician, the birth of a small human in my family inspired me to create a mathematical toy for the tiny person to enjoy while learning about shapes. With my favourite platonic solid being the icosahedron, it was the obvious choice for a knitted toy, and with stellation being all the rage, sticking a point on each face was the obvious next step, especially when it’s such a convenient thing for tiny inexperienced hands to grasp.
David’s de Bruijn sequence card trick
A few days ago, my friend David asked me if I could help him with a card trick. I said I could, hence this post. I managed to pin David down in front of my camera long enough for him to demonstrate the trick; a full explanation follows this video:
A glider on an aperiodic cellular automaton exists!
Good news, everyone! I literally jumped out of my seat and punched the air when I saw this story. It’s as if this site was set up specifically to report on this exact piece of news.
Carnival of Mathematics 89
Welcome to the 89th Carnival of Mathematics, this month hosted here at The Aperiodical. While The Aperiodical team is involved in administrating the Carnival (more information about the Carnival can be found here), it is hosted on a different blog each month. Last month cp’s mathem-o-blog was the host for Carnival of Mathematics 88, and next month the Carnival will be hosted by Mike Croucher at Walking Randomly.
The Mathematician’s Shirts
Patches ready to sew
The shirt symbolizes the formality of a male-dominated society and of conformance to society’s rules. Mathematics, too, is a realm of formality and rules populated largely by men. Yet in both shirts and mathematics there is room for creativity and individuality.
In The Mathematician’s Shirt project, artist Madeleine Shepherd and mathematician Julia Collins set about challenging these notions by turning a collection of formal shirts (donated by mathematicians!) into mathematical art. Inspired by the work of mathematicians in Edinburgh, the fabric of the shirts got twisted into 4-dimensional shapes, woven into knots and stitched into different geometries.
