    Default Cool Video

    You may recall from a Mechanics course that the period of a pendulum is proportional to the square root of the length of the line suspending the weight - i.e., the longer the pendulum, the slower it swings.

    Harvard students built a device with a series of 15 pendulums in a row, each one slightly longer than its neighbor, then set them in motion and filmed the result.

    The resulting patterns in this short video are quite fascinating to watch.

    Watching that and listening to Pink Floyd I thought I was back in the '60's
    To grow old is inevitable.... To grow up is optional

    Confidence, the feeling you have before you fully understand the situation.

    What could possibly go wrong.
