Another article last week, Do Inferior Numbers Scare Women Away From Science And Engineering?, expressed concern that there aren't enough women ( and minorities ) in science, engineering and math. A lot of math and science and engineering is getting done, it is just getting done primarily by men and that is a concern.

But why? I know why it should be a concern. I have enough of a liberal leaning to reflexively know it is supposed to be a concern but that is balanced out by age and the hard-earned realization that spending more money, in the case of awareness programs, or implementing quotas won't actually produce better science.

A new infrared imaging system that automatically counts the number of people in cars could offer a cost effective solution to help lower congestion and carbon emissions - or it could be a handy government monitoring system.

Carpool lanes are not popular. In Britain 20% of the road capacity is used by multi-occupancy vehicles. In a state like California that percentage is even less, around 7%, yet every highway has 'carpool' lanes.
