ELI5-What is entropy?
In: 1763
Entropy is our measure of our level of uncertainty of the state of a system that arises from our inability to discern the microscopic state. Particularly, the position and momentum. If both of these were known for each particle, there would be no uncertainty given that the trajectory would be known and therefore deterministic. In a simulation of atoms (eg MD), there is no entropy, the entire state of the system is known. Humans are just bad at knowing the microscopic state and formulated ideas based upon that.
