Items: Physics, astronomy, space, math, illusion
Buncha cool stuff here, including some videos and music, on various geeky topics.
- Physics of Oobleck (that is, of corn starch and water). You really must take a look at the pictures on the Vibrated shear thickening fluids page, and particularly at the astonishing movie. Be sure to watch all the way to the end of the movie for some amazing Cthulhoid action.
- Nudging asteroids away from Earth using gravity. Like an extremely slow tractor beam. Sort of.
- Turns out tinfoil helmets are themselves a government conspiracy.
- No thing goes faster than light, but what about optical pulses? This article reads like it was meant to be a layperson's explanation, except that I can't understand most of it. But thought it was worth linking to anyway.
- Screen saver showing almost-real-time images of the sun.
- A speech written by William Safire in 1969 "in event of moon disaster," to be given if the Apollo 11 mission failed.
- International Space Station celebrates 5th anniversary.
- Pretty math patterns.
- It looks like a faux segment from Zoom, but it's really a music video of "Pi," by Hard 'n Phirm. Odd and entertaining.
- Archives to Wear Pants To is very silly. Note particularly the song I Am the First Fifty Digits of Pi, in the May 11 entry.
- Weird and kinda creepy optical illusions from MIT's Computational Visual Cognition Laboratory.
