If the cup of water is in a specific microstate at time t=0, and evolves over time according to deterministic equations of motion, how will it "access" other microstates that aren't along that specific trajectory in phase-spa

That would be a circular calculation, because the foundational definition of temperature is rooted in entropy: T = 1/(dS/dQ). You can measure the temperature of a brick with a thermometer, but then you should understand what that

That's a very good, and deep, point, and I agree that there is something important there. However, algorithmic complexity is still only defined relative to an arbitrary reference computer. If my reference computer happens to, in hardwa

I respectfully disagree. Perhaps you'd like to present more than a mere assertion to make your case. I did. If it helps, here's a paper that explains my stance in more detail. https://bayes.wustl.edu/etj/artic

Just because inflation is being caused by supply constraints, doesn't mean that raising interest rates is an inappropriate response.

Alright. I agree we seem to be stuck in a weird loop where we agree about all the observable facts but somehow are on different wavelengths in spite of that. And I totally agree, entropy is a property of a macrostate. The information step c

"similar" is in the eye of the observer! This fact should be especially clear in the context of bit strings. If 10010001111110101000 is my login password, don't be surprised if other permutations fail to grant you access, eve

> If you take this very same system and put it in thermal contact with another system, then an objective entropy perspective is the relevant one. Those systems will equilibrize and your subjective knowledge is irrelevant to that process.

The concept of entropy wasn't invented so that we could calculate entropies of macrostates, it was so that we could calculate entropies of real systems and understand their behaviour. Macrostates are an accounting tool that helps us do

No, it is subjective. We just only have such blunt instruments for practically measuring states, relative to the gargantuan amount of entropy in most real systems, that the subjective nature of entropy is easy to miss. But in a world where

Can you elaborate on the difference between a "fine-grained" macrostate and a macrostate that is not fine-grained? I think you will find it hard to separate the concept of a macrostate from the state of knowledge (or ignorance) of

Not the GP, but entropy production is any process that increases your ignorance about a system (and usually, if you're doing it intentionally, everybody else's ignorance as well). To produce entropy you have to grow the number of

The way to make sense of entropy is to treat it as a subjective quantity. A subjective quantity is a function where the observer's state of knowledge is one of the input arguments. The article describes it as a measure of hidden infor

Yes, it's possible. The components needed are very small. However I think it would risk people damaging their device (or their fingers) by trying to crank-charge the batteries too zealously.

That's a 50 basis point hike. It might have a cooling effect on Canada's runaway housing market. I wonder if the Bank of Canada has inside information that the US Fed will be doing the same in May.
