Do Photons Cast Shadows?
This video is about two-photon (gamma-gamma) physics, and how photons can interact with each other - either mediated by a passing lepton, or gravitationally via lensing, or via vacuum fluctuation pair production of vertical particles...

Is the Universe a Computer?
The universe is made up of information, similar to a computer, and physics (you know, the basis of the universe) certainly is based on computational principles. But is it running some grand program? Will the answer be 42? Make sure you...

Contour Lines
In this video Paul Andersen explains how contour lines show areas of equal elevation or equal gravitational potential. Contour lines are used as an analogy for lines of equipotential in electric fields.

Why Astronomy Hasn't Really Changed Since the 1900s
The way modern researchers study the sky hasn’t really changed in the last few centuries. For the most part, astronomers still study things by analyzing their light.

Why We're Building Underground Telescopes
Obviously most telescopes need to see the sky to do their job, but when you are studying a wave that can pass right through the earth, the best place for your telescope might be underground.

Why It's HARD To Land on Mars
This video is about why it's harder to successfully land spacecraft and landers and rovers on Mars than on Earth, or Venus, or the Moon, or Titan, or asteroids. It all comes down to atmospheric density! When there's no atmosphere, you...

How Earth’s Tides Gave Us Life As We Know It
While astronomers are busy searching for life beyond Earth, they’ve also started asking another question: If life seems so difficult to find, then why is our world so full of it? One answer might be overhead right now: the Moon!
