Via Robert Reich: "UFC event on the White House’s South Lawn...to attend, military members have to pay their way to Washington and cannot have a waist size more than 55 percent of their height." Not enough to serve the country. It's like it's a contest, how to make this the most disgusting.

Give the kids a grapher with parametric sliders, and they'll give you a decent polygonal fit to points, then show you the local peaks. Source: Actually doing calculus-inspired activities with enthusiastic K-2 kids. Prediction: the kids who don't care are more into topology than analysis.

Important story about what actually happens when you add police to schools- they overpolice kids. It is not an easy job to deal with children and teens- police are clearly not trained for it.

I just hate this narrative so much. Generally love @pbsnews.org coverage, and they avoid just blaming teachers and cell phones, but so ignore larger equity issues and just what these tests are doing. Who should PBS interview to get a better perspective? www.youtube.com/watch?v=Kt37...

Happy international workers day everyone !

I was looking around in my computer and found this I made in December 2016. It's all 216 of the "clock polygons", that is, the polygons that can be made by joining some of twelve equally-spaced points around a circle.
