Farewell 2*19*53

2014 has been a crazy and amazing year. I got an amazing new job, attended multiple math art conferences in Asia, and made all kinds of fun things.

I thought I would end 11111011110* with an homage to my first post of the year on shortbraid and other geometric cookies, by making a regular polyhedron out of gingerbread and chocolate ‘glue’.

The dodecahedron** is a particularly nice shape to close the year with because it has 12 faces – one per month!*** If you want a fun mathematical New Year project, you can make yourself a dodecahedron calendar.

I considered doing a corresponding month by month round-up of my favorite posts, but I apparently didn’t bother to make a post last January. Instead, I leave you with my delicious and oddly healthy gingerbread recipe for anyone interested in making their own geometric cookies.


3 oz. melted coconut oil
1/2 cup molasses
1 tsp. baking soda mixed with 1 Tbsp. hot water
2 cups whole wheat flour
2 tsp. ground ginger
2 tsp. ground cinnamon
other appropriate spices if you like
pinch salt
1/2 cup ginger chips/chopped candied ginger (optional)

  1. Mix liquid ingredients and dry ingredients (except ginger chips) separately, combine. I use a Kitchenaid mixer for this.
  2. Mix ginger chips into dough.
  3. Shape dough into a log, wrap in plastic wrap and stick in the freezer some time that is at least long enough to firm up, but could approach indefinitely
  4. Pre-heat oven to 350 degrees Farenheit
  5. If you just want circles, slice dough as thin as possible and set pieces on cookie sheet (no need to grease)
  6. If you want to make other shapes, let dough warm up a bit, then roll it out as thinly as possible and cut out your shapes
  7. Bake for ~10 minutes, let cookies cool before starting any cookie geometry construction

Finally, gingerbunny ears!****

* I’m unreasonably excited that 2015 will be a palindrome in binary.
** It’s also my favorite platonic solid.
*** Or, as in a recent Vi / eleVR / everyone project, the same number of tones on the scale and days of Christmas…
**** Yes, as you can see in the background, my house is kind of overflowing with random geometric constructions.
