We use our high resolution Johansson indicator and some gage blocks to take precision measurements of Sharpie thickness.
A putter is a 'putter together of scissors.' This short documentary by Shaun Bloodworth follows the work of Cliff Denton, who works at Ernest Wright & Sons of Sheffield, one of the last remaining hand manufacturers of scissors. More from the BBC, with Eric Stones, the other Master Puttertogetherer at the factory.
Badass Japanese Precision Walking Competition. Craziness starts at 1:45, and just gets better from there on.
The London Underground. Every Londoner has used it, but has everyone really seen it? The old map is looking a bit dusty. Perhaps its time for Geographic precision or maybe 3D projection. If we add bicycles to the map, is it still an underground? [more inside]
Americans, German win nobel prize for physics. They won for for their contributions to the development of laser-based precision spectroscopy, including the optical frequency comb technique, which among other thing allows them to measure the speed of light to such accuracy that it is now used as the definition for the meter, see if the laws of physics were the same at the beginning of time, and make gps satellites work much better.
