Balancing a stick with a weight is a challenge that requires good hand-eye coordination. Let’s explore this feedback system: Hand – Stick – Eye. Read more…

Our Berkeley students of “Physics and Music” went on a field trip to the Exploratorium. Thanks everyone for coming, love your Physics and Musics T-Shirts!

Forgot your IPod headphones? You need nothing but a coil of wire, a magnet, and a small plastic cup to make your own! Click on the picture for a larger size.

Many thanks to Modesto Tamez for showing me his magic…

Here are some examples, try to guess what the original sentence said:
