June 11, 2010 | David Smith

The Earth is pretty big. Give or take, it's about 36,000 feet (11km) to the height of a 747 soaring above Everest, and (in pleasing symmetry) about the same distance down the bottom of the Mariana Trench. (Nonetheless, if you shrunk the Earth down to scale, it would still be smoother than ... [Read more...]

Because it’s Friday: Stochastic degradation

June 4, 2010 | David Smith

When you upload a video to YouTube, they don't store a perfect digital copy of your media file. The video is actually re-encoded into the MPEG-4 video format. This saves space on YouTube's servers, but also introduces some random degradation to the video (as a result of the lossy compression ... [Read more...]

This one's for the musicians out there. (By the way, in my purely anecdotal experience, musical aptitude appears to have a higher-then-expected representation amongst stats folks.

Because it’s Friday: Pixels invade New York

April 9, 2010 | David Smith
