The sqrt function returns the principle square root, not both. That’s true for all numbers, positive, negative, and complex alike.

Why should productivity and corporate tax rates be correlated at all, up or down? The link there is not obvious.

If you’ve played KSP you should know how totally useless Mun bases are.

There isn’t anything magically about precisely zero percent interest rates; the behavior we see is mostly a smooth extension of slightly higher rates, which the EU was at.

And of course ZIRP was pioneered in Japan, not the US.

IRV is also vulnerable to third-party spoilers; the squeezed middle is a well-known phenomenon in that system.

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

Why would you ignore the largest state in that land area calculation? Alaska still isn’t quite enough to push the US up, but it’s good for another 20%-ish increase in land area over the contiguous number.

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…)

Historically speaking the things the rich think are worth spending money on haven’t lined up with what society thinks is best all that often.

“Your total money is decreasing” is not the same thing as “all your money is gone” - it’s leading in that direction, but if it takes 20 or 30 years to get there that’s usually enough for people to retire on.

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.

Boston Dynamics is trying to produce for the military market. The field doesn’t generally have huge expanses of well-maintained concrete to drive on.
