    The most glaring and revealing example of this is travis kalanick talking about QM. It should be embarrassing and disqualifying for leadership to be so easily fooled, but he just g…

    It depends on whether we take care of them at the cost we currently are in the west.

    I for one am not surprised.

    We used to just call that efficiency. Overusage of "pareto frontier" annoys me almost as much people talking about "electrons" instead of just saying electricity or power.

    I kind of do the conversation tracing thing already. Every change is attributed by Claude code session id (and timestamped obviously), then I have a jq based tool over cc session j…

    I was probably projecting. I like both path and equilibrium entropies, but my assumption I guess was that when people hear entropy in physics they're usually thinking of the equili…

    But paying so little attention to it that it no longer is a core competency? As in, the people most representative of that competency leaving in droves? I doubt that was the plan.

    I don't think Google is that freaking short-sighted. Even if you're not trying to be frontier, the value of having domain knowledge via experience for AI is worth saving internal c…

    This makes a lot of sense to me. Probably doesn't explain everything but I could see it explaining a lot. Could also explain openai and anthropic delaying IPO (among other factors)…

    It depends entirely on whether they're trying to and failing vs. being strategic. It smells a lot more like the former to me.

    That is the entropy rate. If I'm understanding your original question correctly, you were asking about the standard equilibrium-defining thermodynamic entropy?

    Find the equilibrium probabilities from first eigenvector, use definition of entropy like you did. If it's not ergodic then you get subsystems with their own entropies. Second eige…

    This predates stochastic thermo quite a bit. Entropy of markov chain is at least 50 y/o, maybe more.

    I ask once again: why is everyone so convinced that nuclear is the one technology that somehow doesn't get cheaper and better with advancing tech and scale? And don't tell me learn…

    Lol no. Latent heat is basically all that matters

    A nice way to guarantee that is not not try.

    I agree, but there's degrees (no pun intended!). Many PhDs are just an advisor telling a student exactly what to do. The training is still valuable, but it's not really what a PhD …

    Why is that only "technically yes"? It's precisely how the thermodynamic and empirical temperature scales are matched.

    The reference point is the triple point, and invariant.

    Maybe masters will become more popular. I have no problem with bars being raised on PhDs, but it's crazy history that math may be the first one to have it raised (or brought back t…
