There are a great many ways to celebrate Pi Day, and food is one of our favorites. While pie is obviously appropriate for Pi Day, there are so many other fun ways to explore math and science through cooking. Here are some of our food projects that can be great ways to explore math concepts on Pi Day:

The tutorial is also available as a Jupyter notebook with runnable code.
Various patterns are generated in Matlab using mathematical equations similar to ones describing Spirograph (or harmonograph) and Phyllotaxis. The patterns are calculated in such a way that when rotated under a stroboscopic light of suitable frequency or when recorded by a camera, they start to animate. It is kind of zoetrope— early device for animation. … Eggs are rotated at a constant speed, special for each pattern, by a brushless motor. No computer graphics tricks are used in the video.
Additional information is available at their site.
We found a remake from our project Make your own 1952 Fraction-of-an-inch Adding Machine on display at Xerocraft, a hackerspace in Tucson. They cut and engraved the calculator out of hardboard using their laser cutter. It’s sturdier than papercraft and it looks great!
KnitYak scarves ship with the specific code and generating key used to make the pattern on your scarf. There is something powerful about knowing the mathematics and code behind the pattern you are wearing.
She’ll be getting an industrial knitting machine for her company KnitYak to automate the process of manufacturing these individualized creations.
For each of the last two years, we’ve released sets of “Download and Print” cards for Valentine’s day. The 2013 set had six equation-heavy cards, and the 2014 set was a set of six symbol-heavy cards. This year, we’re releasing six new cards, bringing the collection up to a total of 18 cards. This year’s new cards feature love, hearts, and arrows (but no bows or cupids):
For when your love is complex, but not whatsoever imaginary.
For that moment when you want to express that not only is the first derivative of your love positive, but so is the second.
(Just in case there was a danger of none of these being sufficiently cheesy.)
Not sure how we missed this one in last year’s set of symbols. Alternate caption: “You light up my life.”
And what better way to say “I love you,” than with the gift of a math problem?
You can download the full set here, which includes all 18 designs from the three years (a 765 kB .PDF document).
As usual, print them out on (or otherwise affix to) card stock, and [some steps omitted] enjoy the resulting lifelong romance.
Update: New cards have been released! Please check out the 2019 set, which contains all 42 cards from 2013 through 2019.
The replica makes extensive use of the so-called “Hoik glitch” in the game, that allows for rapid, controlled player movement, much like gravity guides the balls downward in the original.
More information about the version in Terraria is posted on the video page.
Last fall, we built an oversized Digi-Comp II for MIT, which we’ll be posting about in the near future. Today, MIT computer science professor Scott Aaronson published a short “paperlet” about the computational capabilities of the Digi-Comp II on his blog, Shtetl-Optimized:
…it’s amazing that such a simple contraption of balls and toggles could already take us over the threshold of universality. Universality would immediately explain why the Digi-Comp is capable of multiplication, division, sorting, and so on. If, on the other hand, we don’t have universality, that too is extremely interesting—for we’d then face the challenge of explaining how the Digi-Comp can do so many things without being universal.
