From CBC News: Supreme Court quashes seismic testing in Nunavut, but gives green light to Enbridge pipeline I think the Supreme Court is erring in maintaining the view that Canada’s Indigenous communities should not have the right to reject proposed resource development projects that affect their territories.

A new simulation called The Evolution of Trust does a good job of introducing the basic concepts of game theory.

The prerequisite for any state embarking on a nuclear weapons program is a complex base of material and people with a diverse set of skills and experience. A 1968 UN study estimates that a full-fledged nuclear weapons program requires some five hundred scientists and thirteen hundred engineers—physicists, chemists, and metallurgists; civil, military, mechanical, and electrical […]
