Keep Them Shutters Rolling, Rawhide!
Gav shows you how insanely quick the inside of a DSLR camera moves when it takes a picture, by filming it at 10,000 fps.
…
Camera filmed is a Canon 7D.
This video is a good demonstration of how a rolling shutter works.

HULK SMASH!
As the video warns, magnets like these are potentially very dangerous.
Quantum is Kinda Crazy With a Spooky Little Thing Like You
Really good explanation of quantum entanglement and how Bell’s inequality rules out local hidden variables.

The Tension is So Thick, You Can Cut it With a GoPro
During Expedition 40 in the summer of 2014, NASA astronauts Steve Swanson and Reid Wiseman — along with European Space Agency astronaut Alexander Gerst — explored the phenomenon of water surface tension in microgravity on the International Space Station. The crew “submerged” a sealed GoPro camera into a floating ball of water the size of a softball and recorded the activity with a 3-D camera. (Video: NASA)
Note: You will need red-blue stereoscopic 3D vision glasses to view the video.
Bottom one is the 3D version, in case you couldn’t figure that out.
The big question for me is how my brother Steve kept being an astronaut a secret all these years.

Physics in the Cloud
One thing glossed over: Joe mentions that the muons are undergoing time dilation by some factor, which allows a fraction of them to live long enough to reach earth, but in their own frame their clocks run normally. How can that work? The missing piece is that the muons see their travel as length contracted by the same factor. They don’t decay because they didn’t travel very far, (or for very long) as seen in their frame.
