I think "most famous events in human history" is probably overstating it, and even then it wouldn't be well known anyways. Outside of the HN bubble, the average 18 year old person (even in america, as opposed to russians) wou

Meh. “We will never produce artificial beef more efficiently than natural beef” is not a hill most people are willing to die on. I’m not even fully willing to say “we will not make a room temperature superconductor” or “we will not make col

On the other hand, a modern SSD is probably faster than RAM on a spaceship from the 90s. (Don’t quote me on this, I didn’t double check). All of a sudden I had an urge to get MS-DOS to run with a SSD as memory. Unfortunately I know DOS can’

It's written in the mathoverflow question, did you read it? > I have access to Maple 2018, and it doesn't seem to have a complete implementation either. A useful test case is the following integral, taken from the (apparently u

This is not true- AWD bias depends on the platform, and not because driving the front wheels are more efficient. Subaru AWD drives the front and back equally. BMW XDrive is rear biased. Audi Quattro drives both axles equally, Quattro Ultra

Did anyone review this article before publishing it? Typos like “precursos”, really?

This is PRECISELY the type of thing that should be discussed in anonymous public forums, with the consent of the person and with neutral questions not for the sake of shaming the person who’s talking. Growth of issues in society should not

Actually, there are infinite orders of magnitude between the resistance of silver and that of a superconductor.

The materials are easily on hand. That doesn’t guarantee it was easy to manufacture. It’s not made of out of exotic elements, mostly just lead and copper. So in theory anyone can make it, but it’s just hard to do it correctly.

Wtf are you talking about? Superconductors are limited to 40kJ/L energy density. For reference, gasoline is 33,000 kJ/L.

Debt obligations denominated in USD? In theory, the US government would never go bankrupt as long as they can print more money. Which they always can, the dollar isn’t backed by gold anymore.

Meh, he discovered why the word “culture” and “cult” share the same root. Or “cultivate”. That’s not some grand observation, any middle schooler can see the obvious reason why they’re similar.

If this material works out and also turns to be massively toxic, then people thinking the way you do is going to cause a lot of lead poisoning. Not fun.

If you figure out how to ensure it gets dropped at the higher energy subsitution site, you would get a nobel prize as well.

Nuclear plants produce 68% of the energy in France. If that’s not statistically relevant, doubling the number wouldn’t be statistically relevant either. For that matter, even in the USA, nuclear power produces about 10% of all electricity.

The number of people the collapse would affect is a whole lot closer to “the total human population” than “1 person”.
