Conservation efforts in Africa have typically been led by "parachute conservationists" -- outsiders who drop in thinking they have all the answers, hire locals to implement them and then disappear. But conservationist Resson Kantai Duff...

This week Craig Benzine discuses bureaucracies. Bureaucracies tend to be associated with unintelligible rules and time-wasting procedures, but they play an important, though controversial, role in governing. From the FDA to the EPA,...

In this video Paul Andersen explains how the electric field between oppositely and equally charged plates is uniform as long as you are far from the edge. The strength of the electric field can be determined by either the charge of the...

The mythical green flash at sunset isn't actually a myth! Stefan explains why it happens, and how you can see it.

It might sound like science fiction, but if you press on a crystal of sugar, it will actually generate its own electricity. This simple crystal can act like a tiny power source because sugar happens to be piezoelectric. Ashwini...

Mr. Andersen shows you how to use the factor label method to solve complex conversions.
