http://projects.metafilter.com/6144/Mondrians%2DToothpicks
Spent the last week executing an idea I had earlier this month: a stained glass piece based on the Toothpick Sequence, a simple mathematical ruleset about line-drawing that generates complicated results. I ended up going with four color scheme for the collection of rectangles and squares, and so: Mondrian's Toothpicks. tag:projects.metafilter.com,2023:site.6144Mon, 30 Jan 2023 11:43:21 -0800artglassmathOEISstainedcortexHow many apples?
http://projects.metafilter.com/6023/How%2Dmany%2Dapples
A couple of years ago, Harvard statistics PhD student Kareem Carr <a href="https://twitter.com/kareem_carr/status/1289724475609501697">ignited a firestorm of debate</a> when he talked about 2+2=5. Apples kept coming up in the debate as the quintessential example of a countable thing. "I have two apples. I get two more apples. Now I have four apples. Always. Math is never wrong." For some reason the example was always apples. Thinking about that finally bore fruit in the making of this: <a href="https://photos.google.com/share/AF1QipO7yAEIjK0MvoixT5iYXINYhe6-NDmoGt_5X-_HCP65cgMX6gy6tduSZ0tX6hLRQg?key=VUpPSzlCN3BEOHpPM3ZTNG1heG9BNmZiSE90ZXFB">How many apples do you count in this image?</a> I'm interested to know your answer to the question posed in the image.

My new book, <em>Shape</em>, comes out this coming Tuesday, May 25! This book is about geometry: in it you'll find gerrymandering, pandemics, the foundations of AI, poetry, math/theology beefs of late-czarist Russia, championship-level checkers, the Talmud, why you are your own negative-1st cousin, wrinkles in time, and a lot more. It's not just about triangles (though there are some triangles in it.) The New York Times <a href="https://www.nytimes.com/2021/05/18/books/review-shape-geometry-jordan-ellenberg.html">calls it "unreasonably entertaining,"</a> and there's <a href="https://www.wsj.com/articles/what-honest-abe-learned-from-geometry-11621656062">an excerpt</a> in this weekend's Wall Street Journal (paywalled.)
<em>Shape</em> is available for preorder now at <a href="https://bookshop.org/books/shape-the-hidden-geometry-of-information-biology-strategy-democracy-and-everything-else/9781984879059">Bookshop</a> and <a href="https://www.amazon.com/Shape-Geometry-Information-Democracy-Everything/dp/1984879057/">Amazon</a>, and of course it will be at your local bookstore on Tuesday! tag:projects.metafilter.com,2021:site.5916Sun, 23 May 2021 22:10:46 -0800bookgeometrymathescabecheFogleworms: a series of modular linocut prints
http://projects.metafilter.com/5893/Fogleworms%2Da%2Dseries%2Dof%2Dmodular%2Dlinocut%2Dprints
I spent the last half of January fixated on a simple mathematical proposition about arranging short twisting lines on a square grid, which I nicknamed "Fogleworms"; the terminus (so far) of that particular obsession is this series of 96 modular linocut prints and their four derived "ghost" prints, each mathematically unique. Besides describing the project in its own right, the writeup collates a lot of my tweeting about the subject and this actual printing project through the end of January and early February; "Fogleworms" comes from Michael Fogleman, the person who originally derailed my brain by <a href="https://twitter.com/FogleBird/status/1349563985268531200">posting this tweet</a>.
When I finally got to the point of creating the prints in this set, I live-tweeted a bunch of the process <a href="https://twitter.com/joshmillard/status/1357120805474213888">in this long thread</a>, including pictures, process notes, and a couple bits of video.
I'm really happy with how the prints came out and with having executed the whole series; I'm interested in exploring the possibilities of this kind of modular print-making further, and like how naturally it lines up with some of my existing inclinations toward system-based and process-based art.
I also recently executed a similarly combinatorial printing project, the <a href="https://www.patreon.com/posts/stop-1-24-47305806">STOP permutations</a>, which is focused on enumerating all the anagrams of the letters in a stop sign. Both the STOP prints and these Fogleworm prints are available for purchase <a href="https://www.etsy.com/shop/CortexCraftworks">on my store</a> if you're interested in owning a piece. tag:projects.metafilter.com,2021:site.5893Mon, 15 Mar 2021 12:01:01 -0800artfoglewormslatticelinocutlinoleummathmathematicsprintseriescortexJ.

http://projects.metafilter.com/4308/How%2DNot%2DTo%2DBe%2DWrong
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 <a href="http://www.amazon.com/How-Not-Be-Wrong-Mathematical/dp/1594205221">Amazon</a>, <a href="http://www.indiebound.org/book/9781594205224">Indiebound</a>, <a href="http://www.waterstones.com/waterstonesweb/products/jordan+ellenberg/how+not+to+be+wrong/10495223/">Waterstones</a>, 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 <a href="http://ask.metafilter.com/239738/How-do-you-say-statistically-significant-in-your-native-language">statistical significance in different languages</a> and <a href="http://ask.metafilter.com/216295/Is-this-famous-investment-scam-real-or-fiction">stockpicking scams</a>, but more importantly because I've learned so much about how to write about math for non-mathematicians from writing about math on MetaFilter! tag:projects.metafilter.com,2014:site.4308Thu, 29 May 2014 10:33:27 -0800bookhownottobewrongmathescabecheExponential Binary Clock Countdown

http://projects.metafilter.com/3957/pilaroid
I'm working on this little toy that takes subsequences from the hexadecimal expansion of pi and represents them as 500x500px images. The quick rundown is that it grabs 500x500 24-bit pixels' worth of bytes from the first billion digits of pi and then turns it into an image with PIL, then you can vote on the ones that look like something cool. There's definitely some humorous intent here because they obviously all look pretty much the same, but I'm thinking about some avenues involving treating the substrings as compressed data, or screening the results for some interestingness criteria, that might result in more compelling images. Anyway, it's pretty much done, although I plan to add some things to make it a little more user- and server-friendly like pagination which I didn't think about as I was testing it. tag:projects.metafilter.com,2013:site.3957Fri, 26 Apr 2013 13:51:45 -0800mathpiwebsiteinvitaprioreMaseno Maths Camp video
http://projects.metafilter.com/3758/Maseno%2DMaths%2DCamp%2Dvideo
<a href="http://www.youtube.com/watch?v=pLQpuAR8quw">This is a video about a math camp</a> 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 <a href="http://www.youtube.com/watch?v=pLQpuAR8quw&t=0m30s">catchy song at the beginning</a> to rope you in and get the idea across more quickly. Finally, there's a <a href="http://blogs.africanmathsinitiative.net/tomd/2012/10/22/math-camp-video-and-general-progress-thus-far/">blog post here</a> outlining a bit of the work we've been up to this year. There are a lot of Big Ideas going into this project. For me, the really big idea is to build up the base of mathematically literate people in Africa to allow the economies to be a bit more independent, and to allow problems to be solved more readily by people with good understanding of the local situation. There's an all-too-common phenomenon of experts flown in from abroad who stay around very briefly, identify a couple problems and prescribe a couple 'solutions' which have little chance of actually working, with a price tag of a few hundred thousand dollars. So why not create a crew of local experts, with knowledge of the local system and the big-level maths and modeling that the foreign experts are so well paid for?
Of course, to do this, you've got to engage with the education system in one way or another. We're working at all different levels, but what you see here is a project at the secondary school level. We're hoping that by opening eyes of students and teachers to a different way to interact with mathematics, we'll be able to raise the level of understanding, and help produce students who are ready to really tackle mathematics wherever they end up. tag:projects.metafilter.com,2012:site.3758Mon, 22 Oct 2012 18:11:29 -0800africacampeducationgameskenyamathmathematicsmusickaibutsuYour Superfund

The first of a serious of neat little side projects from my usual work on <a href='http://mapbox.com/'>MapBox</a> 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 - <a href='http://macwright.org/2011/07/28/mapping-runs.html'>I documented the process of creating the map in serious detail</a>, and it goes over re-teaching myself high school trig, writing a scraper for <a href='http://connect.garmin.com'>Garmin Connect</a>, trying to fake being a real artist, and figuring out some new map interactions.

I'm a big fan of recreational mathematics. I would, from time to time, poke around <a href="http://oeis.org/">The On-Line Encyclopedia of Integer Sequences</a> 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. tag:projects.metafilter.com,2011:site.3078Mon, 11 Apr 2011 08:18:48 -0800blogmathmathematicsnerderyPlutorOnline Math Quiz
http://projects.metafilter.com/2943/Online%2DMath%2DQuiz
Get a random, 64 question addition/subtraction test on every view! The inputs take only numbers and auto-tab to make it easy on young users, and answers are checked (and locked in) instantly. At the end, the correct/incorrect count and time are displayed. Tests can also be printed (click off of the first box to hide the cursor).
This originally began (way back... last night) as just a practice sheet generator to help my daughter with her timed math tests, to avoid the numerous shady or inadequate "resources" online.
However, that being a little too easy (and the results a little too school-like), I decided to make it interactive.
The problems are mostly random, only controlled so that a larger number is never subtracted from a smaller one (and therefore, you may see the same problem twice in a row).
There is plenty more I could do, but this meets our needs for now, and I didn't expect anyone other than myself to use it (I'm making this first projects post at the suggestion of a couple of #bunnies).
If there is interest, I'd be happy to share the (kinda ugly) PHP/jQuery source, add features or maybe put it up on a real host. I haven't tested it in every browser, but it is great in Chrome and at least functional in IE8. tag:projects.metafilter.com,2011:site.2943Thu, 27 Jan 2011 13:46:50 -0800mathonlinequiztestMr. AnthropomorphismSketches, Comics, Math, Word Games and Other Oddities
