The PHun stuff about PHYSICS

I'm taking a physics class at KU this semester. It is called the Physics of SPEECH. We are learning all about the nature of waves. This is a video of the Tacoma Bridge disaster. The wind caused the bridge to vibrate and on this day, the frequency of vibration matched a natural resonant frequency of the bridge, eventually causing it to break apart. From what I read online, the only fatality was a dog named Tubby who refused to jump out of the car.
