This video will make your head spin, trust me. I’m gonna tell you everything about rotation. Everything rotates: from galaxies to atoms, the Universe is taking us for a "spin." You’re gonna learn why the surface of the Earth is moving at all different speeds at all different latitudes. And how "leap seconds" are added to the clocks to synchronize our clocks with the slowing rotation of the Earth. Remember: what goes around, GOES around!
