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 …

Who cares if you listen?
I pride myself on having big ears, on listening to everything I can and trying to find the beauty in it. I’ve learned to enjoy some aspect of just about every kind of music. Every kind except one: high modernist twentieth century classical music. I just can not deal with it, at all. But I’m …
Music theory and quantum mechanics
In high school science class, you probably saw a picture of an atom that looked like this: The picture shows a stylized nucleus with red protons and blue neutrons, surrounded by three grey electrons. It’s an attractive and iconic image. It makes a nice logo. Unfortunately, it’s also totally wrong. There’s an extent to which …
How is Earth’s gravity generated?
Gravity is the warping of spacetime by mass or energy. 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 …
So what is the big deal with Einstein?
I’m a humanities guy, but I’ve never lost my childhood love of math and science. I’m looking forward to the Large Hadron Collider being fired up next year the way normal male Americans look forward to the NBA playoffs. I like to be an informed fan, and since Einstein is the Michael Jordan of scientists, …
