Preventing mass atrocities and genocide is a core …

Preventing mass atrocities and genocide is a core national security interest and a core moral responsibility of the United States.

Our security is affected when masses of civilians are slaughtered, refugees flow across borders, and murderers wreak havoc on regional stability and livelihoods. America’s reputation suffers, and our ability to bring about change is constrained, when we are perceived as idle in the face of mass atrocities and genocide.

Emphasis mine.




Our mission is to empower the residents of Highland Park, MI through the planning of installation of 200 community-owned solar-powered streetlights.

Why would they have to do that? Because…

In 2011, the city made a deal with DTE energy. To forgive an outstanding $4 million of electrical debt, a reduction of the street light footprint was negotiated. In total, 1100 streetlights were repossessed, leaving the thoroughfares lit, and neighborhoods dark.

And so residents are taking matters into their own hands. Highland Park, by the way, is a city located entirely within the city of Detroit.

A Visual, Intuitive Guide to Imaginary Numbers

Square roots and negative numbers came up the other day.

Imaginary numbers always confused me. Like understanding e, most explanations fell into one of two categories:

  • It’s a mathematical abstraction, and the equations work out. Deal with it.
  • It’s used in advanced physics, trust us. Just wait until college.

The explanation I gave was the first one. I never got far enough in college physics to experience the second one. But this handy guide actually made it make some sense. I’ve got nothing to use it on, but I do feel better now.
