A Science Odyssey Guest 2 wearing an Albert Einstein mask

What's the deal with matter?

I am an atomist. I believe that all matter is made up of minuscule particles called atoms. It is the properties of these atoms that give matter its properties.

There are other minuscule particles that inhabit our Universe, too. These particles are responsible for light. Indeed, these particles are striking the retinas of your eyes this very moment -- they enable you to see the absurd mask I am holding in front of my face.
