A couple months ago I shared some GIFs of invisible things, and I finally got around to putting them together in this video:
When light travels through areas of different air density, it bends. You’ve probably noticed the way distant pavement seems to shimmer on a hot day, or the way stars appear to twinkle. You’re seeing light that has been distorted as it passes through varying air densities, which are in turn created by varying temperatures and pressures.
Schlieren Flow Visualization can be used to visually capture these changes in density: the rising heat from a candle, the turbulence around an airplane wing, the plume of a sneeze … even sound. Special thanks to Mike Hargather, a professor of mechanical engineering at New Mexico Tech, who kindly provided a lot of these videos.
I’m totally Schlieren right now. Amazing sights of sounds.

We will live again
Fascinating, retrofuturistic, tragic and eerie. Worth a look.
WE WILL LIVE AGAIN looks inside the unusual and extraordinary operations of the Cryonics Institute. The film follows Ben Best and Andy Zawacki, the caretakers of 99 deceased human bodies stored at below freezing temperatures in cryopreservation. The Institute and Cryonics Movement were founded by Robert Ettinger who, in his nineties and long retired from running the facility, still self-publishes books on cryonics, awaiting the end of his life and eagerly anticipating the next.

can we start a club for teenagers who were constantly complimented on their intelligence when they were younger and are now having trouble coping with the realization that they’re actually of average intellect at best

Nothing like period week to make me really miss working at an ice cream parlor. Unlimited access to sugar and cream to quell your hormonally driven needs.

Well, this was motivating.

Ocean Beach, SF
Since it’s only two hours away, I usually try to make it to the ocean at least once a month. I missed it completely in January with all the shit flying around in life, but there’s no reason for me to miss February.
