I spent the last few days hand-painting a couple of fractal images—a Menger sponge and a Cantor set—on the wall of my home office. This is a writeup of how and why I did it, with some bonus thoughts on the weird nature of the fractal series behind the images.
I'm currently taking Harvard Business School's HBX CORe, an online business fundamentals course that covers analytics, accounting, and economics. I'm writing up what I'm learning and making it accessible to non-MBA types. Topics covered include minimum wage, the math behind trendlines, and why the Spiders Georg meme is off, amongst others!
After three years of work, my book HOW NOT TO BE WRONG: THE POWER OF MATHEMATICAL THINKING comes out today from Penguin Press! It's about math. Also: baseball, Reaganomics, daring lottery schemes, Voltaire, the replicability crisis in psychology, Italian Renaissance painting, artificial languages, the development of non-Euclidean geometry, the coming obesity apocalypse, Antonin Scalia’s views on crime and punishment, the psychology of slime molds, packing 24-dimensional spheres, what Facebook can and can’t figure out about you, the invention of calculus, and the existence of God. The book is available at Amazon, Indiebound, Waterstones, and (I hope!) your local bookstore. MetaFilter has been a fantastically useful resource for me in putting this together; partly because I can use Ask for my questions about statistical significance in different languages and stockpicking scams, but more importantly because I've learned so much about how to write about math for non-mathematicians from writing about math on MetaFilter!
This is a fairly simple concept site to try to convey just how enormous exponential growth becomes. It counts to 2^63rd power at 100 increments per second, with notes about what might be happening when that next bit, in this case a square on an 8x8 grid, turns black. Hoping people can use it as a tool to inspire a little wonder in math.
I have been working with video journalist Brady Haran on a series of hand made animations for science videos. Other videos include:Numbers Confuse Americans, Maths Jokes Explained and Lagrange Points. I'm currently auctioning the drawings used to make the dimensions video here.
Voronoi Monologue is an "infinite series" of drawings based around malformations of voronoi patterns. [more inside]
I'm working on this little toy that takes subsequences from the hexadecimal expansion of pi and represents them as 500x500px images. [more inside]
This is a video about a math camp in Maseno, Kenya, that I've helped coordinate for the last two years. The idea is to give secondary school students a new perspective on mathematics, and expose teachers to activity-based teaching methods. We're aiming to get across the idea that math is about the concepts rather than the drills, understanding rather than mindless computation, beauty rather than grades. The video runs about 13 minutes, but there's a catchy song at the beginning to rope you in and get the idea across more quickly. Finally, there's a blog post here outlining a bit of the work we've been up to this year. [more inside]
What environmental catastrophe is your neighbor? A map of all 1.6k Superfund sites and an instant finder for your own by using some interesting math hacks.
The first of a serious of neat little side projects from my usual work on MapBox and the like - a new kind of map (I call it a 'squiggle') and a new pretty map. But, hopefully a lot more than that - I documented the process of creating the map in serious detail, and it goes over re-teaching myself high school trig, writing a scraper for Garmin Connect, trying to fake being a real artist, and figuring out some new map interactions. There's more to come, and ideally this convinces the big groups that hold onto our data to let us get at it to make more beautiful things.
MathFall is a genre defining, or genre defying, iPhone game that features elements of both puzzle and arcade gameplay. It is also a great educational tool that hones your math skills...in real time. [more inside]
I'm a big fan of recreational mathematics. I would, from time to time, poke around The On-Line Encyclopedia of Integer Sequences and be startled both by the sheer volume of it, and also by the nuggets of deeply interesting sequences I would occasionally find. After a year of dithering, I've finally started keeping a blog discussing (in brief detail) interesting sequences found therein.

This is an ongoing collection of sketches and comics that I have worked on. Check out the word frequency table and words diagrammed from chart's rules. There is even some speculation on squaring the circle. There are a couple of comics, and even some abstract sketches. More to come...
Some people believe that patterns or structures are the fundamental reality. I would like to find more of these people.
