This channel is dedicated to all things science: the laws that keep our world spinning, our sun shining, and our sifts sifting. Darwin, amnesia, hexafluoride, quantum mechanics, Bill Nye - we've got it all! (Except for lupus. It's never lupus.)
Be proud that although quality science videos are somewhat rarer to come by and harder to find, we do not play to the lowest common denominator, that rather our Science sifts are raising the bar and challenging all sifters to step up and THINK.
On a casual note, what belongs here: science-related sifts, obviously. Please be sure not to sift technology-only videos, or slightly geeky/nerdy videos. Videos belong here only if there is something definitely about science in them. This can include appropriate descriptions, so be sure to add more reading material when possible. In addition, if the video is intended to be factual and not parody, it must be reasonably scientifically accurate and in keeping with scientific thought.

The robot is controlled by visual servoing, i.e. the user clicks a spot and the computer steers it there.
