4-Billion-Pixel Panorama View From Curiosity Rover 101

Posted by samzenpus from the take-a-look dept.
A reader points out that there is a great new panorama made from shots from the Curiosity Rover. "Sweep your gaze around Gale Crater on Mars, where NASA's Curiosity rover is currently exploring, with this 4-billion-pixel panorama stitched together from 295 images. ...The entire image stretches 90,000 by 45,000 pixels and uses pictures taken by the rover's two MastCams. The best way to enjoy it is to go into fullscreen mode and slowly soak up the scenery — from the distant high edges of the crater to the enormous and looming Mount Sharp, the rover's eventual destination."

Submission + - Facebook Buys 750 IBM Patents (bbc.co.uk)

Submitted by eldavojohn
eldavojohn writes: Considering IBM's portfolio gained 6,180 last year alone, it's not a huge number. But after a dispute with Yahoo a couple weeks ago, Facebook has purchased 750 patents from IBM. That's over thirteen times the 56 they were reportedly holding. The humorous rumor is that Yahoo might have been licensing these patents from IBM. If you can't beat 'em, buy the patents they're licensing from another company. Another rumor is that Facebook might just be getting started in their bid to expand their patent portfolio. No word yet on if the purchased patents directly pertain to Yahoo's infringement claims on messaging, privacy controls, advertising, customisation and social networking.

Submission + - 'Antimagnet' cloak hides objects from magnetic fields (nature.com)

Submitted by ananyo
ananyo writes: Researchers have made a cloak that can hide objects from static magnetic fields, realizing a theoretical prediction they made last year. This 'antimagnet' could have medical applications, but might also subvert airport security.
The cloak's interior is lined with turns of tape made from a high-temperature superconductor. Superconductors repel magnetic fields, so any magnetic field enclosed within a superconductor would be undetectable from outside. But the superconductor itself would still perturb an external magnetic field, so the researchers coated its external side with an ordinary ferromagnet. The superconductor tries to repel external field lines, whereas the ferromagnet tries to draw them in — together, the two layers cancel each other out (abstract).

It seems that more and more mathematicians are using a new, high level language named "research student".
