Dare to elaborate why Maxwell's equations got better, and the use cases in the gaming industry which improved thanks to dropping them?
esturk · 2 years ago
Assuming this is not a tongue in cheek question, you can read about it more here:

https://hsm.stackexchange.com/questions/8173/did-maxwell-ori...

The answer also includes a link that shows many other representations including Einstein's "4d generally covariant tensor calculus".

The point is that the most common formulation today is not the one Maxwell made (with 12 equations). The idea is preserved, but it was Gibbs and Heaviside that formulated the current 4 equation representation.

Chemotherapy means "Chemical Therapy" so this is still technically categorized under that. But the general term has gotten really negative in recent decades so I suppose it's why they're distancing the branding from it.

Wasn’t it around this time last year that Google had their big layoff? I suppose the rumor that Google implemented stack ranking might be true after all.

For LFP you can supposedly pack the cells very tight, as they require less thermal management if I understand correctly. And you’re HAVE to do this optimisation for LFP to have decent pack level energy density.

For Li-ion cells, you need that empty space for cooling of the battery cells anyway.

And Tesla has demonstrated that cylindrical cells can contribute to the structure in a structural battery pack.

So for Li-ion I don’t think cylindrical cells are worse. There’s just different trade-offs.

But yeah, one of downsides it can be hard or impossible to replace individual cells if they have problems.

It doesn't matter how much you "pack the cells very tight", there's a geometrical limit here.[1]

And in practice, you'll have modules of sections of the battery for repairing which drops the efficiency to below 90%.

> What if you're the patient?

What if you are on those 10 poor kids he mentioned ?

I don't agree that OP statement is "crass". It's a very pragmatic and important question we have wrestle with.

Except those 10 poor kids aren't spending their own money to save themselves. The patient is though which is the point.

I don't agree that it is nothing. 2 millions, if applied properly, could do good for many people. Take ten children from poverty, give ten children chance to get a good education, etc.

There is always a some kind of moral dilemma: should you spent millions to try to extend extremely I'll person or help with that money to some healthy poor children?

esturk · 2 years ago
Such a crass statement. What if you're the patient? Would you spend 2 million to live 30-40 more years? It's so easy to step back and weight the lives of other as if you're making the decision for others.

Many animals seem resistance to cancer. Including big animals like whales where you'd think if was simply statistics on cell division they would be more likely to get cancer.

But size/height does play a role in humans. For example, shorter people tend to live longer average lifespans.[1]

esturk commented on US Smartphone Shipments Decline 19% in Q3 2023 as More Americans Delay Upgrade   counterpointresearch.com/... · Posted by u/flykespice
onlyrealcuzzo · 2 years ago
Apple's Mac business is doing poorly and the iPhone business is not doing particularly well. It's one of the biggest losers in this upgrade cycle delay, with Nest/Pixel being the only manufacturer growing.

Being bullish on excess capitalism during a slow down doesn't seem like a no-brainer play to me.

But to each their own.

Realistically, I'm just not sure how much growth Apple has left unless India becomes a gigantic market and pulls of a China miracle of its own.

It's already by a large margin the largest private company in the world...

esturk · 2 years ago
Did you even read the article?

First thing, Apple is the smallest loser in this upgrade cycle. Being only downed 11% compared to downed 37% for Google.

Second, the only manufacturer growing is Motorola. Not Pixel/Next.

I just want to point out this is only aimed at coal power plants. This has nothing to do with other uses of coal which is used for steel making. According to the EIA, a little over 90% of coal is used for power[1]. But there is close to 10% of that used for Steel.

You miss-spelled stress.

It's horrible.

esturk · 2 years ago
"Link" implies correlation which in this case doesn't explain the causality of renting private homes part.

The underlying "hidden variable" might just be "poverty". So the causal relation would be something like:

Poverty -> Stress -> Faster biological ageing

Poverty -> Renting private homes
