Seattle local food blogger Deborah Gardner has made something truly amazing—combining the delicious Jewish traditional filled cookies called hamantaschen with wondrous math geekery.
It's Purim, so I'm making the hamantaschen recipe my grandmother z"l developed while she was alive, and passed down to me. It's my family obligation to make this recipe now every year and send hamantaschen out in boxes (gifts called mishloach manot) to my family and dear ones. I've done my best to preserve this recipe; I've written it up in the New York Times, I've taught workshops on how to make it for two Purims in a row, and I've committed to the family hamantaschen-baking role.
But this year, I did something else. You may be familiar with the Sierpinski triangle, a mathematically attractive, self-repeating fractal that starts with one equilateral triangle and breaks down into ever-smaller triangles.
Somehow this year it dawned on me that the world was incomplete without a Sierpinski hamantaschen, or sierpinskitaschen. I scoured the vast reaches of the Interwebs, to see if this had been done before. I may have missed something, but it seems this has not.
Instructions (and some neat Sierpinsky Triangle facts) can be found at the Seattle Local Food blog.

The deadly 2013 El Reno tornado was 2.5 miles (4 km) wide and killed a team of tornado experts. But as Anton Seimon explains, his colleagues turned that tragedy into an opportunity to confirm a key element of tornado formation.
Some snakes have evolved the ability to glide through the air. For example, paradise tree snakes in southeastern Asia can launch off from a branch and fly as far as 10 meters. Scientists have known that the snakes flatten their bodies to gain lift but new research reveals that they also undulate their bodies as […]
The notion of two people sleeping in the same bed always inspires romantic visions of love and intimacy. However, most quickly realize that the romance of sleeping together is often quickly replaced by the realities of the act. One partner snores. The other talks in their sleep. One grinds their teeth. The other hogs the […]
Add Internet of Things to the shortlist of those actually benefiting from the effects of the COVID-19 pandemic. You might not realize it, but the organizing principle that is bringing more automation to the world is actually proving to be a major asset as human beings are forced to stay home and away from the […]
We’ve all had those nights where we’re working on a laptop or scrolling through our phone before glancing at the time to find it’s actually a lot later than we thought. Most nights, you’d be fast asleep or at least dead tired at midnight or 1 or 3 a.m. But after staring at a screen, […]
