Scientists have directly derived the air-sea momentum exchange at the ocean interface using observed ocean currents under Hurricane Ivan and determined that it decreases when winds exceed 32 ...

Instead, Einstein was able to derive a law that we still use today, governed by one of the simplest but most powerful equations ever to be written down, E = mc 2. A nuclear-powered rocket engine ...

This formulation adds in momentum, or p, and also multiplies it by the speed of light. Written out, the equation is: E^2=p^2c^2 + m^2c^4. In the case of a photon, for which m=0, the equation boils ...
