It was invented by neutrogena in 2008...... I think.
The wave pendulum was first demonstrated by Richard Berg in the 1980s. It consists of an array of swinging pendulums that transfer kinetic energy in a wave-like pattern, creating mesmerizing visual patterns.

A thermionic thermometer is a device that measures temperature by detecting the electrons emitted from a heated surface. It relies on the thermionic emission phenomenon, where electrons are released from a heated cathode and collected at an anode to generate a measurable signal related to the temperature of the cathode.
Percy Spencer invented the microwave in 1945

Surf boards were invented in the 1400's by the hawian people.
Electromagnetic wave were discovered not invented.

A thermionic thermometer uses the thermionic emission of electrons from a heated filament to measure temperature. When the temperature increases, the emission of electrons also increases, allowing for a correlation between temperature and electron emission. These thermometers are used in high-temperature applications and can provide fast response times.
