    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.

    Science!

    I wrote this song a few years ago now, but tradition dictates I repost it today.  Let’s all raise a glass to Saccharomyces cerevisiae!

    Well, yes, I would like to listen to a song about the science of beer, thank you. —Lars

  3. They had no real response to music.

    — 5% of people in a recent University of Barcelona study said they got no pleasure from music

    Welcome to NPR’s brand spankin’ new science tumblr. Here, we’ll be sharing animations, explanatory videos, illustrations, science gifs, extras from radio stories, dispatches from the intersection of science and culture, home-made lava recipes, underwater operas, and fascinating graphs hastily scrawled on napkins. Some posts will come directly from NPR’s science coverage, some will come from the incredible bounty of the internet, and some, hopefully, will come from YOU.

    A note about our (odd) name: Skunk bear is a nickname for the wolverine. It climbed to the top of the list of possible names with all the ferocious strength of the world’s largest terrestrial mustelid. Wolverines are known for their voracious appetites - they consume everything from voles to caribou.  And … here comes the connection … this tumblr is a place for you to consume a diverse feast of science stories, ideas and images.

    This has nothing to do with music, but is great and you should follow. SCIENCE! —Lars

  5. The same brain system that controls our muscles also helps us remember music, scientists say. But the discovery might never have happened without The Beatles.
