That's an interesting thought.
I had a glass statue that my sister slid along the surface of a hutch to put it back in position. About 15 seconds after she took her hand off it, we heard a loud *PING* and the thing was cracked right in two.
How about that. That’s a strange one.
I’ve been told that military members never cross bridges while marching in step. That may no longer be true or it may have been an old wives tale. The idea was to avoid rhythmic vibrations.
Harmonics as I understand it, is the study of waves or vibrations. A wave or vibration of one length or cycle would cause no problem, but if adjusted could cause a buildup of tension in an object to the point it could weaken or break.
I’m sure you’ve seen examples of the singer who hits a certain note and the goblet shatters. It’s the same thing. Hit just the right harmonic wave and poof. Adjust the wave and no problem at all.
Harmonics. I think a snooze is in order. Good night. Oh, it’s morning.
Bye.
