The Ancient Inca Acoustic Resonator And Agricultural System Of Moray In Peru

Invention on Instagram: "Acoustic levitation is a scientific technique that uses the pressure of sound waves to suspend small objects in mid air. By arranging sound waves so that they meet and create points of high and low pressure, scientists can trap lightweight particles at these points and hold them steady without any physical support. What appears to be a kind of magic trick is actually a carefully controlled application of physics. The process relies on the fact that sound waves carry ener

How do you hear a bomber before you see it? You build a GIANT EAR. 👁️👂 This was acoustic location, and it was wild. #History #TechTok #LearnOnTikTok On-Screen Text (to pair with the video): (Scene 1) These were the front-line defense before radar.
