Planetary orbits are elliptical because gravitational interaction over time changes the delicate balance of mass, velocity and distance from the star which otherwise keeps planetary orbit circular. For a very long time, from Ptolemy to...

In 2014, the world avoided a global outbreak of Ebola, thanks to thousands of selfless health workers -- plus, frankly, some very good luck. In hindsight, we know what we should have done better. So, now's the time, Bill Gates suggests,...

The Higgs Boson. What more need be said?

This video discusses the concept of planetary movement or orbit. The video also touches on the different shapes of orbits, the forces of gravity that keep objects in orbit, and the balance between momentum and gravity that is necessary...
