I don't think that is exactly ground breaking news
I thought of calling it 'information', but the word was overly used, so I decided to call it 'uncertainty'. [...] Von Neumann told me, 'You should call it entropy, for two reasons. In the first place your uncertainty function has been used in statistical mechanics under that name, so it already has a name. In the second place, and more important, nobody knows what entropy really is, so in a debate you will always have the advantage.'
Conversation between Claude Shannon and John von Neumann regarding what name to give to the or attenuation in phone-line signals.
Now if you had told me that you had worked out what Entropy was I might have got excited.
I should also say that under Quantum Mechanics there are far more compelling reasons why Entropy can't be something real.
- You can show Entropy is a unitary invariant.
Where was the last "real" thing you ever saw that was unitary invariant.
- Entropy can only go to zero if and only if you a pure state
Where was the last "real" thing you ever saw that could only be found to be not there if you provide a specific state.
