Kentucky Color: Lesson in Physics

By Billy Joe Fudge

Went home for lunch and received a free, refresher Introduction to Physics course, courtesy of one of our local rock quarries, a chance placement of two empty glasses sitting in the bottom of our kitchen sink and silence.

While standing at the sink, silently contemplating my options for a quick lunch, the two empty glasses which were either barely touching or barely not touching, double dinged! In the immediate, two second aftermath my mind waxed back to the July 27th 1980 Earthquake which rattled Kentucky. I glimpsed Libby, her brother Todd and me waking Shay, Cameron and Prindle to get them out of our shaking house.

Then and almost immediately, the sound waves from a blast at one of our local quarries arrived. Sweet relief poured over me at the realization that this was not an earthquake. Thankfully, it was only shock waves from the blast which had dinged the glasses.

Then, I remembered from my Introduction to Physics and Chemistry class in high school taught by Ms Ethyl Scott and her very able student teacher Linda Grider, that shock waves travel faster than sound waves.

Thankful for good teachers and the "refresher" courses we get along the roadways of life.
