Earth's Libration Visualized For the First Time Above the Moon's Far Side 33

StartsWithABang writes Thanks to the fact that the Moon is tidally locked, we can only see 50% of its surface on any given night. Over time, the fact that the Moon's orbit is elliptical, and that it moves faster at perigee and slower at apogee means that up to another 9% is visible over the course of many years. The observed "rocking" and growing/shrinking of the Moon over time is known as lunar libration, an incredibly interesting phenomenon. But now, for the first time, we've been able to visualize how the Earth appears to move as seen from above the far side of the Moon.

+ - Amsterdam Central Train Station Sports a High-Tech Rainbow->

Zothecula (1870348) writes "Every night, for just a short time after sunset, Amsterdam Central Station becomes Rainbow Station. A four-kilowatt spotlight projects a stunning rainbow through a custom-designed liquid crystal spectral filter onto one of the station's 45 by 25 meter (148 by 82 feet) roof arches, just above platform 2b. This liquid crystal optics technology is being developed for research on exoplanets, but it will light up Amsterdam Central – and the lives of thousands of travelers – every night for a year."

Yeah, I remember that one. The petrol in station was way the hell out in the middle of nowhere (for the UK, anyway), and was already on the expensive side as a result. The owner said that he wasn't profiteering, rather it was about conserving what little they had. Until they could get another delivery, he wanted to ensure that anyone who wasn't desperate didn't stop there, and anyone who was only bought enough to get them to civilisation.

Made sense to me. Didn't make sense to the Daily Mail, of course.

+ - Microsoft's age-old image library 'Clip Art' is no more->

hypnosec (2231454) writes "Microsoft has finally bid a goodbye to the age-old Clip Art image library found in its Office products as its usage has been declining over the years. Redmond replaced the Clip Art’s online image library with Bing Image Search. This means that people searching for online images inside an Office app will now be directed to a gallery powered by Bing Images that will bring in results from around the web. Bing's copyright filter based on the Creative Commons licensing system will let users get royalty-free images which they can use, share, or modify for either personal or commercial use."

the annoyance of the lights turning off all the time because occupancy sensors suck

...which is why the one in my office has a paper coffee-cup duct-taped over it and I bought a small desk lamp with an old-school switch. All the offices here have these sensors. But all the toilets, where you don't want to touch anything, have wall switches - even in the individual cubicles.

The universe does not have laws -- it has habits, and habits can be broken.
