Cooling is the main and normal direction heat pumps run in; heating is the new and unusual way to use them.

Decimal Time 3 years ago

c is used in the definition of the meter, but you don’t remotely need to know that in day-to-day life. As long as the seven base units (length, time, mass, temperature, electric current, luminosity) end up with reasonable values the system is practically coherent.

(are the values reasonable? well, human-scale capacitors and resistors seem pretty heavily skewed away from the center of the scale…)

Inner Speech 3 years ago

I imagine it’s just an ingrained use of language picked up from other people - no thought behind it, like an atheist who says ‘Christ’ as an expletive.

It’s very hard to see a situation where it’s logistically feasible for the US to transport so many people over that it exceeds the number of soldiers already in the military.

The US military has about 1.5 million people at present. When Germany surrendered in 1945, the US had about 3 million people in Europe alone - entirely ignoring the whole Pacific front.

It is generally unwise to underestimate the logistical capabilities of the US military.

(The other points seem more grounded, especially about the nature of modern western war.)

Unfortunately it’s generally more complex than that, at least in US law - simply having material nonpublic information isn’t enough. It really matters how you got the information.

For example, when Hindenburg Research did a ton of research and discovered that Nikola was basically totally fraudulent, they traded extremely relevant information that wasn’t publicly available. Not insider trading.

Similarly, if Warren Buffet invests in a company, he knows that its stock is very likely to go up (just as a result of the halo effect around him). He doesn’t have to disclose that he plans to buy, though.

A charge usually takes 20-30 minutes. You get a five minute grace period, then you start getting hit with $1/min idle fees. That’s barely enough time to get from the far reaches of the parking lot to a store and back.

Bringing the food closer to the charging station fixes that. No idea about the drive-in, though.

(Of course it also brings with it the risk of a spot getting ICE’d, which is why charging stations are so far out in the first place. Dunno how they plan to avoid that.)

Are you suggesting people just go read the documentation like an encyclopedia? I don’t know a single person who got their start programming by doing that - just about everyone wants some sort of guide to help lead them in good directions.

Negative Mass 3 years ago

Phonons can have a negative effective mass - in other words, you can mostly ignore the effect of the background environment if you simply change the mass to be something else (which can be negative).

That’s very different than having a negative actual mass.
