Complexity and Life

Lecture no. 14 from the course: Mysteries of Modern Physics: Time

Complexity and Life

Taught by Professor Sean Carroll | 31 min | Categories: The Great Courses Plus Online Science Course

Discover that Maxwell’s demon from lecture 10 provides the key to understanding how complexity and life can exist in a universe in which entropy is increasing. Consider how life is not only compatible with, but is an outgrowth of, the second law of thermodynamics and the arrow of time.

This course should rather have been named "All about entropy". The teacher make a great job at explaining this notion. However, the link with what is time is much less obvious. This obsession of physicists with entropy remains kind of a mystery to me. Because, as says the teacher, entropy is not a fundamental law of the universe. It it like pressure or temperature. It is an emerging law of a macro system. Therefore, time seems to be more fundamental than entropy than the other way around. In fact, you need to have movement (of particules) to have increase in entropy. Therefore, you need time in the first place.
