Why Were The Founders Of The Heliocentric Model Always Shown Holding A Compass? 👁️🧭 Newton. Galileo. Copernicus. Kepler. And Why Does Freemasonry Use The Compass & Square? Simple. The Compass Draws A Circle Not A Globe. The Square Draws Straight Lines Perfect Angles. 90°. Circle + Straight Lines. Not Curves On A Sphere. Symbols Tell The Truth If You Know How To Read Them.

Despite what you see, the balls are all in a straight line. Your mind creates the circle

A rotating ball casts a shadow that perfectly matches a mass on a spring, revealing how circular motion and simple harmonic motion are linked. A visual proof of sine-wave physics in action.

Using Physics to Extinguish a Fire. 🔥 Hydraulic ventilation is done by setting up a hose line on a fog stream and directing it OUT of a window. The air that a fog stream draws in also draws out the smoke and ejects it outside.

This experiment shows how objects moving in a circle instantly travel in a straight line when the force holding them disappears. SpinLaunch uses this same physics idea to launch rockets
