Everything goes better with fire: Jared Ficklin at TED2012

Jared Ficklin‘s passions are music, technology, and making things. And he brings them together to visualize sound — with fire. Real fire on stage. He’s built a Ruben Tube, a long copper pipe with a hundred holes on it, attached to a tank of propane. He turns on a tune at 550 Hertz, and the tube responds, showing a standing wave of fire. (The audience applauds hesitantly, and Ficklin assures them, “It’s ok to applaud the laws of physics.”)

Then he gets to the real fire: a fire table, and he puts on some jazz, to show us the eigenmodes, gentle waves that respond to this music. It’s a subtly beautiful response to the jazz guitar he puts on. And we learn: “Jazz is better with fire. Actually, most things are better with fire.”

That’s wonderful, but “Fire is just the foundation.”

He has a rendering algorithm that he uses to visualize entire songs into a picture in two dimensions. He’s used it to visualize everything from Nirvana albums to the sounds of skateboarders, from which he can tease out social dynamics.

He also took the entire Cambridge lectures of Stephen Hawking, rendered all the sound, and placed a star at the end of every sentence. Then he removed everything but the stars, and produced a beautiful rendering that looks exactly like a Hubble photo. Enough people thought the image was fake that he created an interactive version, where you can go in and pick a star and hear the sentence that generated it.

Finally, he shows the beginning of a TEDTalk, with the sound off but the sound visualization below, and demonstrated just how easy it was to see the patterns of music, applause and speech. Because, as he says: “Eyes can hear.”
