Although at that point, your attempts to cut the state will probably resemble a look-up table enumerating every valid board state, which obviously balloons the executable size by a large amount.

yes but there could conceivably be better tricks to discover

> Entropy isn't a function of imperfect knowledge. It's a function of the possible states of a system and their probability distributions.

There are no probability distributions over possible states when there is perfect knowledge of the state.

> Quantum mechanics

Entropy is also zero for a pure quantum state. You won’t have entropy without imperfect knowledge.

I know very little about physics but I thought that the leading interpretations of quantum physics say that the probability distribution is all we can know about a system. The entropy is not due to due to a lack of information about the quantum state, but because the outcomes are inherently stochastic?

I don't get it.

To me, entropy is not a physical thing, but a measure of our imperfect knowledge about a system. We can only measure the bulk properties of matter, so we've made up a number to quantify how imperfect the bulk properties describe the true microscopic state of the system. But if we had the ability to zoom into the microscopic level, entropy would make no sense.

So I don't see how gravity or any other fundamental physical interaction could follow from entropy. It's a made-up thing by humans.

It sounds like you're talking about information entropy which to my understanding is analogue to but not the same as entropy in physics?

It was never going to last if the US allowed for very low cost imports from those countries. This is literally one of the largest points of tariffs - protecting domestic manufacturing. We could have had high tariffs the whole time and offshoring would have been much less pronounced. I'm not saying that would have been a net positive, but to say it would never last is only true under certain circumstances.

You were still going to lose export markets as international competition grew, and you were still going to shift to higher value-added service jobs as the economy developed.

Americans have been hurt for 50 years … yes manufacturing going overseas was a huge change and many administrations didn’t do enough to help affected workers. Buuuuuut - placing tariffs on our allies that will likely lead to a recession makes no sense.

Devaluing the dollar and subsidizing production in the US makes far more sense.

But I’m not an economist or anything.

America got richer and outgrew the phase where tons of factory jobs made sense. It seems pretty clear to me that well-paying manufacturing job in developed countries were the product of a particular moment in time where poorer countries couldn't do it yet. Now they can. It was never going to last.

How long do I have to study math to understand this?

to understand what they said, or to understand a proof of why it would be true?

any stats class would be enough to understand what they said

I am not sure whether the videos are representative of real life performance or it is a marketing stunt but sure looks impressive. Reminds of the robot arm in Iron Man 1.

OK. Other people (probably not you) in this thread were talking about this strategy like it was basically risk-free. Compared to a naked short it's, um, obviously a better idea, but I still think others were over-selling it by not mentioning all of the downside risk.

whereismyacc · 6 months ago

Oh yeah, I don't think I would suggest actually implementing this because it's just a lot of costs and fees to emulate what otherwise would be an index without the stock
