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 #3, "Force, Energy, and Action." Already I have backslid on my idea that every idea would be encapsulated in just one word, but these three seemed to flow together.
