| - | Entropy is a measure of chaos or randomness in a system. An important property of entropy is that it increases over time. In practice that every system gets more chaotic over time unless we use energy to bring it into order. | + | Entropy is a measure of chaos or randomness in a system.

| An explanation for this steady increase of entropy is that there are far more possible states of high entropy than there are states of low entropy. | An explanation for this steady increase of entropy is that there are far more possible states of high entropy than there are states of low entropy. | ||

| - | The, in the beginning purely empirical, observation that the observation of a system always increases, can be deduced from general logical arguments as was demonstrated by Jaynes. | + | The, in the beginning purely empirical, observation that the entropy of a system always increases, can be deduced from general logical arguments as was demonstrated by Jaynes. |
| Entropy is a macroscopic notion like temperature and is used when we do not have absolute knowledge about the exact micro configurations of the system. | Entropy is a macroscopic notion like temperature and is used when we do not have absolute knowledge about the exact micro configurations of the system. | ||
