Just to be clear, the problem was not with my intuition about temperature. The problem was trying to put toghether
"all those configurations with no particles near the thermometer -which may be very concentrated or not at all- have the same entropy"
and
"the entropy is lower the more concentrated the particles".
For example I wrote two days ago: https://news.ycombinator.com/item?id=33206422 https://news.ycombinator.com/item?id=33206422
"In every single initial configuration the particles will be at some distance from the thermometer and will cause it to read 0 according to you reasoning (until some time passes). I guess they all correspond to the same "absolute zero macrostate".
What I still don't see is how do you calculate the entropy using Gibbs entropy formula in such a way that the entropy is lower or higher for some initial configuration depending on the position of the particles."
Or somewhere up this thread I said very clearly "The balls don’t touch the thermometer in either case. You seemed to imply that the higher concentration means a different macrostate with lower entropy."
and you insisted that "Yes. The higher concentration has a lower probability of occurring. And occupies a different temperature reading on the thermometer. Each temperature reading is a different macrostate."
It's not my fault that you insisted that the higher concentration has a lower probability of occurring and occupies a different temperature reading on the thermometer even when I was clearly talking about what you say is the same macrostate with the same temperature.
