Welcome to warp zone

When I was a kid I played a lot, and I mean a lot, of Super Mario Bros. My grandpa once asked me to explain the game to him after he’d watched me play it for the nine thousandth hour. I tried hard and couldn’t do it. There’s a lot that defies intuition. Like how [...]

A synthesizer is like an axe

I found this picture of Herbie Hancock on some dude’s blog. There was no caption or any other context. So I posted it on my Flickr with a note asking if anyone could identify the computer Herbie is sitting in front of. A couple of days later my friend Mike responded with this video of [...]

Learning music theory with Auto-tune

Auto-tune makes producing music easier. It can also make understanding music theory easier. The way you dial up different keys and scales doesn’t just guide your ear, it also guides your eye. Your voice can produce a smooth continuum of pitches. To sing, you eliminate most of those possibilities, vibrating your mouth and throat only [...]

Tuning the quantum guitar

In high school science class, you probably saw a picture of an atom that looked like this: The picture shows a stylized atom, a nucleus with red protons and blue neutrons, surrounded by three grey electrons. It’s an attractive and iconic image, and it would make a great logo. It’s also misleading, and in some [...]

Robot counting for humans

When you delve behind the scenes with the internet, you immediately come face-to-face with a lot of threatening computer gibberish. The most menacing codes are the ones that stand for colors, random-seeming strings of letters and numbers like #99CC66 or #4F102A. Sometimes you see colors described verbally: “black”, “white”, “blue”, etc. That’s fine for simple [...]
