Looks like it is talking about the same thing: > OpenAI has raised $8.3 billion at a $300 billion valuation, months ahead of schedule, as part of its plan to secure $40 billion in …

How much UX superiority is due to the shorter lines? I definitely prefer self-checkout at Walmart, but if their cashiers were as efficient as e.g. ALDI it wouldn't be as valuable

I was the same way when I was a beginner, I didn't really "get" python classes until years later and using other programming languages. I recommend SICP if you want a more first pr…

When accounting for negative externalities such as "unpriced natural capital consumption", it seems only fair to also include positive externalities, such as "food/energy availabil…

This is awesome, thanks for sharing so much detail. Btw one thing I noticed, the link to "Determinate Systems" was broken. I think this is the correct link: https://determinate.sys…

Another big draw to me is that the checkout process is fast and efficient. Take a look at the packaging and you will notice the barcodes are massive to facilitate rapid scanning.

There is a distinction in drug development between the biologics (large proteins, e.g. https://en.wikipedia.org/wiki/Adalimumab , molecular weight ~144kDa), and small molecules htt…

For most of human history the population growth rate was limited by the food supply. Currently in most developed countries it is limited toby individual decision-making. How long c…

Xenophon (c. 430 – 354 BC): 1. “Leaders must always set the highest standard. In a summer campaign, leaders must always endure their share of the sun and the heat and, in winter, t…

If it wasn't selectively rewritten, it wasn't important enough (to be selectively rewritten).

Based on this equation, shouldn't high speed trains consume less energy since they travel so much slower than planes (3x speed = 9x drag)?

I think it would sound more metaphorical if you removed the indefinite articles, instead starting with "The river cuts through rock"

Trees are still falling into swamps. The difference is that microbes can digest lignin/cellulose now.

I would agree that American policies have increased the size of our healthcare sector, but is this really something that can be attributed to free market decisions? How much more g…

I looked at the citation, someone put the wrong numbers in the pie chart: https://en.wikipedia.org/w/index.php?title=Energy_in_the_Uni...

1. The USA has the best doctors and hospitals. The marginal benefit to having better doctors and hospitals is completely dwarfed by their higher prices. Would you be willing to pay…

>The problem with hydrogen as fuel storage (mainly for space travel) is the pressure, operating a fuel tank at 400 gPA or higher is going to be tricky Operating a fuel tank at 1 MP…

It doesn't, what he is saying is that the companies that do crash and burn after revealing salary information to their employees are the ones that should crash and burn. There is n…

One result worth noting is that checkout line speed is faster when each worker has their own line. http://web.ics.purdue.edu/~yrosokha/docs/Humans%20Are%20Not%...

Not quite yet, orbital missions are much higher energy than lobbing something to space. Specific energy of New Shepard booster at apogee: ~1000 KJ/kg Specific energy of Falcon 9 bo…

Energy and momentum are always conserved. Elastic collisions conserve kinetic energy. This is helpful to know because you can predict the final speed of the two objects after the c…

The rest of them. Lithium is only the electrolyte. They also need cathode and anode materials. Specific energy of gasoline: 46.4 MJ/kg Specific energy of high end Li-ion batteries:…
