AMAZING Interactive Entropy explainer by Aatish Bhatia: http://aatishb.github.io/entropy/

This video is about why entropy gives rise to the arrow of time, and also how the initial low-entropy condition of the universe is responsible for the fact that we experience time right now, and how ultimately it will lead to the high-entropy heat death of the universe.
