There’s no question that comets have been regarded as some of the most beautiful things in the night sky for thousands of years. But why are their heads often green but never their tails?

If you look closely enough, you'll see the night sky is actually a little green. SciShow Space explains the science behind the phenomenon known as airglow.

Engineering student Péter Fankhauser demonstrates Rezero, a robot that balances on a ball. Designed and built by students, Rezero is the first ballbot made to move quickly and gracefully -- and even dance. (Could the Star Wars sphere...

In this video Paul Andersen shows conceptual thinking in a mini-lesson on stability and change. Two examples are included in the video and two additional examples are included in the linked thinking slides. ...

Four of the heaviest elements on the periodic table are finally getting names!

In this video Paul Andersen explains how we can use Coulomb's law to predict the structure of atoms. These predictions can be verified through the use of Photoelectron Spectroscopy (PES). Electron's are help around the nucleus because...

Recently, humanity filled the periodic table up to atomic number 118, which nicely rounds out that row. But are we done yet? Have we discovered all of the different elements? And what is an "island of stability?"

Paul Andersen explains how energy is conserved within a system. In both macroscopic and microscopic collisions the amount of energy before the collision is equal to the amount after. He then defines heat as energy transfer between...
