"The color content of a beam of light can easily be identified by running the beam through a prism," Baird told Live Science. "These simple, cheap, handheld objects spread out the beam of light into its various pure color components. Each pure color has a distinct wave frequency." That's why scientists tend to use the words "color" and "frequency" interchangeably, because a ray of light's color is defined by its frequency — for visible light, red has the lowest frequency and violet has a highest.

Hayabusa2 will jettison its sample container when it’s about 100,000 miles away from Earth, roughly half the distance between our planet and the moon. Once the capsule has touched down, it will be recovered by a team of Japanese researchers stationed in the scorching Australian desert. It will immediately be brought to a temporary clean room built on site so it can be analyzed for any volatile compounds like water that may have been contained in the sample. Within hours of recovering the capsule, the researchers will puncture its hull and bottle any gases that may have been released by the sample and save them for analysis.

Also, be warned about the $10 engraving option. Microsoft is opting to use the same gray typeface for your custom text no matter what color it's printing on. Even on the white pad, it looks a little faded and weak, but on the "storm gray" pad, it blends in and can be easily missed, especially if the shiny plastic reflects even the tiniest bit of light. Unless you're desperate to have some words pre-printed on your controller, we recommend you save the $10. The default price of $80 is already a lot to spend on a gamepad, after all. … [Read more...] about Seeing the Xbox Design Lab work from Web interface to couch reality
