The Biggest Ideas in the Universe | 23. Criticality and Complexity

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 #23, " Criticality and Complexity." Having spend a lot of time on the basic ingredients of our universe, it's time to contemplate how they come together to make complex systems. The idea of critical behavior -- things happening at all spatial scales -- is an important organizing principle.
