Officially, tuning forks were invented in 1711 by John Shore, a British Musician. Unofficially, their existence traces back to ancient Celtic and Egyptian times.

Nowadays they are used mainly for testing hearing, tuning musical, keeping time in a quartz watch, and teaching the principles of vibration and resonance in the classroom. The alternative health community uses tuning forks for healing purposes.

But what did the ancients use them for? I believe they were mainly used to cut, drill, and levitate stones. I will provide some information in this note regarding these applications.
