Physics: Featured Facts
The Coriolis Effect
Physics / Atmospheric

Hurricane Elena The Earth, rotating at about 1000 miles per hour (1,609 km/hr), influences the flow of air and water on its surface. We call this the Coriolis Effect, named after French scientist Gaspard Coriolis, wh continue reading this fact

The Weakest Force
Physics / Fundamentals

Gravity Is the Weakest! Did you know that gravity is the weakest force in the universe? Well, it's true! There are four fundamental forces (that we know of) in our universe: Strong Nuclear, Electromagnetic, Weak Nuclear an continue reading this fact

Tick-Tock Atomic Clock
Physics / Fundamentals

24 GPS satellites orbit Earth. Modern navigators rely on atomic clocks. Instead of old-style springs or pendulums, the natural resonances of atoms -- usually cesium or rubidium -- provide the steady 'tick' of an atomic clock. The b continue reading this fact
