The next issue of the Carnival of Mathematics, rounding up blog posts from the month of December, is now online at Ganit Charcha.

The Carnival rounds up maths blog posts from all over the internet, including some from our own Aperiodical. See our Carnival of Mathematics page for more information.

Mathematical Obituaries, December 2018

As 2018 drew to a close, we sadly lost several pioneering figures in mathematics. UPDATE: We have sadly also lost Rich Haberman, added 14/1/19.

Happy Thirdsday!

Today is the third of January, and the third day of the year – and since this year it also falls on a Thursday, making for excellent pun opportunities, a group of mathematicians including Jim Propp, Evelyn Lamb, Zoe GriffithsBen Orlin, Matt Parker and several others have chosen to use today to celebrate the number $\frac{1}{3}$ (and in America, you’d even write the date as 1/3). Today is officially Thirdsday! Celebrate by:

I personally will be sketching the middle third Cantor set, as it’s my favourite fractal.

Not Mentioned on The Aperiodical, 2018

We’ve had a bit of a break over the holidays, but mathematical news stops for no mince pie. From new prime numbers to mathematical doodling challenges, here’s a round-up of some of the facts/stories that we’ve seen while trying not to do any work.

Aperiodvent, Day 23: Cellular Automata and Snowflakes

Friend of the site Andrew Taylor has a host of fun gadgets on his website, the Christmassiest of which has to be this Cellular Automata Snowflake Generator. It allows you to iterate two deterministic processes that model aspects of real snowflake generation, and create your own beautiful designs.
