An interesting article about the discovery of a new type of electrical device. Based on the equations relating charge and magnetism, Leon Chua deduced that the mathematics of electric circuits was missing an element (one that directly relates charge to magnetic flux) - he dubbed the missing element a memristor.
Now scientists believe they have found a physical device that has this effect ... at nanoscales. The device could have some amazing applications for computation.

Strange but interesting - stratified warm water layer at the surface can make it very difficult to swim (and even cuts the speed of power boats).

New material has reflective index of only 0.00045.
Thanks, Tosh!
Quoted: U.S. researchers said on Tuesday they have made the darkest material on Earth, a substance so black it absorbs more than 99.9 percent of light.

MIT's Physics lectures - by the best physics lecturer in the world. You can watch the complete course on video for FREE on MIT's Open Courseware website (unfortunately, you need Real Player - but I find that the Real Player is less obnoxious than they used to be).
Quoted: This section contains the video index and videos for the various topics of the course.
