Here’s a new invention that, while potentially useful, is even more interesting as an illustration of the nature of sound: the acoustic prism. When light enters a prism made of some refractive material, the sub-components of that light have their paths affected slightly differently, based on their wavelength (color); the …

It’s Computer Science Education Week, in case you didn’t know, and in honor of this hallowed period Microsoft is publishing the thoughts of a few of its scientists and engineers on what will change in the tech world over the next decade. Seventeen women were asked to chime in — …
