Entropy is a concept that appears in various fields, such as thermodynamics, information theory, and statistical mechanics. Its meaning can vary slightly depending on the context, but generally, it refers to a measure of disorder, uncertainty, or randomness in a system. 1. **Thermodynamics**: In thermodynamics, entropy is a measure of the amount of energy in a physical system that is not available to do work. It is often associated with the degree of disorder or randomness in a system.
OK, can someone please just stop the philosophy and give numerical predictions of how entropy helps you predict the future?
The Unexpected Side of Entropy by Daan Frenkel

Source. In usual Sean Carroll fashion, it glosses over the subject. This one might be worth watching. It mentions 4 possible definitions of entropy: Boltzmann, Gibbs, Shannon (information theory) and John von Neumann (quantum mechanics).- www.quantamagazine.org/what-is-entropy-a-measure-of-just-how-little-we-really-know-20241213/ What Is Entropy? A Measure of Just How Little We Really Know. on Quanta Magazine attempts to make the point that entropy is observer dependant. TODO details on that.
