Assignment Discovery: Atoms on the Surface
Atoms make up the very structure of all things, and if your microscope is powerful enough you can see them. Learn more about how atoms are arranged on the surface on Discovery Channel's "Assignment Discovery."
Assignment Discovery: Electron Shells
All atoms in their ground state are electrically neutral and have an equal number of electrons and protons. Learn more about atoms on Discovery Channel's "Assignment Discovery."
Assignment Discovery: Graphite
Graphite is a carbon based material that is an electrical lubricant and very brittle. It can be used to make a pencil. Learn more about graphite on Discovery Channel's "Assignment Discovery."
Assignment Discovery: Material Science

Master of the Universe: Annihilation of Atoms
Atoms are unpredictable. It's hard to be certain if they exist or not. Space, at an atomic level, has an energy field full of particles that annihilate each other. Learn more about atoms on The Science Channel's "Master of the Universe."
Master of the Universe: Stephen Hawking on Atoms
On The Science Channel's "Master of the Universe," Stephen Hawking and colleagues describe what atoms are and suggest they are more like force fields and waves, rather than mass.
Science of the Impossible: Fusion Energy
On Discovery Channel's "Science of the Impossible," learn how fusion energy technology could take astronauts to the next nearest star, Alpha Centauri.
Science of the Impossible: Intro to Zero Point Energy
Zero point energy is the force that preserves the structure of the universe. The possibilities are endless if we can one day harness the power from zero point energy. Learn more about zero point energy on Discovery Channel's "Science of the Impossible."
