- People say many things about entropy: entropy increases with time, entropy is disorder, entropy increases with energy, entropy determines the arrow of time, etc.. But I have no idea what entropy is, and from what I find, neither do most other people. This is the introduction I wish I had when first told about entropy, so hopefully you find it helpful. My goal is that by the end of this long post we will have a rigorous and intuitive understanding of those statements, and in particular, why the universe looks different when moving forward through time versus when traveling backward through time.

Haller Lake (Lushootseed: sisaɬtəb) is a small lake and neighborhood in north central Seattle, Washington, named for Theodore N. Haller, who platted the neighborhood in 1905. His father, Granville O. Haller, was one of Seattle’s early settlers, an army officer who amassed a large estate in the region.
