A Science Odyssey Guest 1 wearing an Albert Einstein mask

What's the deal with matter?

Here's the deal: Matter is made of atoms, and atoms are made of protons, neutrons, and electrons, as well as even smaller particles. It is all described by quantum theory.

The world of the atom is strange -- unlike anything that you or I can imagine. For example, depending on how it is measured, an electron appears to be a wave or a particle, but never both. It's what I call complementarity.
