I recently posted a track on SoundCloud that included the sonification of LIGO’s gravitational wave data. A student asked me what that meant. Since today is Albert Einstein’s birthday, what better time to try to formulate an answer? https://soundcloud.com/ethanhein/ligo-chirp First, some context: 1.3 billion years ago, two black holes collided. Each was about thirty times as …

Space Oddity: from song to track
If you have ever wondered what it is that a music producer does, David Bowie’s “Space Oddity” provides an excellent example. A producer turns this: into this:
Were the Beatles great musicians?
Most of us agree that the Beatles made great music. But some people don’t believe the Beatles to have been especially good musicians. Quincy Jones famously called them “the worst musicians in the world.” He’s exaggerating, but he has a point. By modern standards, the playing on Beatles records is sloppy. The parts are interesting …

The specifics of the gear and the plugins are interesting, but the main takeaway is just how complex and nuanced the soundscape …

A mass like the Earth warps spacetime so that the shortest path, the “path of least resistance,” for inertial movement is towards the Earth’s center. Using instruments like the Hubble Space Telescope, it’s possible to literally see the warping of spacetime by very massive objects …
Dig the big bang
In Annie Hall, young Woody Allen explains to his doctor that he won’t do his homework because the universe is expanding, so what’s the point? His mother exasperatedly tells him, “You’re here in Brooklyn. Brooklyn is not expanding!” I post this because I’ve been reading Coming Of Age In The Milky Way by Tim Ferris, …
Life in one day
Our creation myths start with the assumption that we’re the most important thing in the world, the reason for everything else’s being. The story that science tells relegates us to the periphery. Life has mostly been smaller and simpler than us. I think it’s important to recognize that we might very easily wipe ourselves out, …
Here comes the sun
Today in the NY Times there’s an article about NASA’s new Solar Dynamics Observatory. Check out this amazing video of the sun in action. The sun was on my mind today anyway, it being so nice and cloudless outside. But days like today also cause me anxiety. I’m a fair-haired sunburn-prone type, and my dad …
