The Biggest Ideas in the Universe | 17. Matter

The Biggest Ideas in the Universe is a series of videos where I talk informally about some of the fundamental concepts that help us understand our natural world. Exceedingly casual, not overly polished, and meant for absolutely everybody.
This is Idea #17, "Matter." The matter of which we are made can be solid because electrons are fermions, meaning that they take up space. We talk about that and the closely related spin-statistics theorem. Complete with demonstrations using visual aids!
