Sympathetic vibratory physics
Sympathetic Vibratory Physics (SVP) is a concept developed by John Ernst Worrell Keely in the late 19th century. It's a blend of science and philosophy that focuses on the idea of sympathetic vibrations—the phenomenon where objects naturally resonate in harmony with external vibrations.

Keely believed that this principle could be harnessed to create revolutionary machinery and improve health and life. His work, although controversial and not widely accepted by mainstream science, has intrigued many over the years.
