“The very molecules that make up your body, the atoms that construct the molecules, are traceable to the crucibles that were once the centres of high mass stars that exploded their chemically rich guts into the galaxy, enriching pristine gas clouds with the chemistry of life. We are all connected to each other biologically, to the earth chemically, and to the rest of the universe atomically. It’s not that we are better than the universe, we are part of the universe. We are in the universe and the universe is in us.”
A couple months ago I sharedsome 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.
Oh my god seriously watch the video. It gave me shivers from its awesomeness.
