My Visit With Galloping Gertie

I wanted to reblog this, a fine travelogue because of the quality pictures!

How I See It

One of the teaching units I enjoyed most in my physics classroom was on wave motions. Almost everything is capable of some sort of waving motion, or oscillation. The motions come in a wide range of frequencies and amplitudes dependent upon the object. Smaller objects tend to have high frequencies and small amplitudes. Large objects tend to have low frequencies and large amplitudes of motion. It is a fascinating field of study.

Some objects respond to an input of energy of some specific frequency and begin oscillating with the same frequency as the source. Their motion can grow in amplitude as the source of energy continues. A simple example is a pendulum with a child on a swing. Pushing the child at the right time inputs energy to drive the amplitude larger. The energy of drawing a violin bow across the strings of a violin sets some of the strings into vibrations that are large…
