Tim Chartier, an Associate Professor of Mathematics at Davidson College, has a series of ingenious and delicious methods for illustrating fundamental concepts from calculus using chocolates. I had a brilliant calculus teacher, Alvin Anson, but I think a little chocolate would have improved even his techniques:
Where’s the chocolate? Rather than shading a square, we will place a milk chocolate chip on a square we would have colored red and a white chocolate chip on a region that would have been white. To begin, the six by six grid on the left becomes the chocolate chip mosaic we see on the right, which uses 14 white chocolate of the total 36 chips. So, our estimate of π is 2.4444. We are off by about 0.697.
Next, we move to an 11 by 11 grid of chocolate chips. If you count carefully, we use 83 milk chocolate chips of the 121 total. This gives us an estimate of 2.7438 for π, which correlates to an error of about 0.378.
Finally, with the help of public school teachers in my seminar Math through Popular Culture for the Charlotte Teachers Institute, we placed chocolate chips on a 54 by 54 grid. In the end, we used 2232 milk chocolate chips giving an estimate of 3.0617 having an error of 0.0799.

The following is an excerpt from my new book, The PrEP Diaries: A Safe(r) Sex Memoir, now available from Lethe Press. The book chronicles the before-and-after of using Truvada PrEP, a recent breakthrough in HIV prevention that has prompted a new sexual revolution–except that most individuals have no idea it exists. Through sex positivity, explicit openness, and fun, I hope to make many more people aware that PrEP is an option for them in not just preventing HIV but having a better, braver sex life.
For years, Anita Sarkeesian and her crew at Feminist Frequency (previously) have been striking terror into the hearts of reactionary assholes by saying calm, smart, funny, sensible and insightful things about how video games reveal our social attitudes.
