The music of the cells

Hundreds of years ago, Pythagoras was listening to the music of the spheres. Today, Dr. Jim Gimzewski is listening to the sounds of a cell.

The device we use to detect the sound of the cells and the motion of the cells is called an atomic force microscope, but it's not a microscope. It's actually a sharp tip that we put on top of the cell and we pick up the motion a bit like you would pick up the motion in a gramophone, in the stylus of a gramophone would transduce motion into some signal that we can then amplify. We have an acoustically deadened room, like a sound studio. And then we just follow, follow the motion electronically. Record that. And then amplify it.

(I dunno...I wonder if the sound is coming from somewhere within the amplification system, but I don’t know much about how that works.) Anyone hear the perfect fourth?
