The place you linked is an outer station in the broader Washington DC metro system. Millions of people live here; trying to view McLean or Tyson’s in isolation is insanity. It’s big because lots of people transit through; the bridges are hi

Graphite flakes from pencils are very flammable and also conduct electricity just well enough to cause shorts.

They weren’t nuclear states.

You started with $10 million. You took out an interest-free loan for another $100 million, so you have $110 million in assets (the money) and $100 million in liabilities (the debt). You’re levered 10:1 because you have $100 in borrowed asse

That subsolar point moves as the earth rotates (of course) but also as the earth revolves around the sun - in January the southern hemisphere is tilted towards the sun; in July it’s the northern hemisphere (this is why seasons happen and wh

I think voting machines can work as long as they print out a voter-readable paper copy of the ballot that is stored and statistically sampled.

The Reformers were/are a group arguing for a particular class of weapons and vehicles in procurement, mostly focusing on relatively low-tech solutions. They’re most famous for their influence in the Fighter Mafia and in the Bradley (se

The US was on the gold standard from 1882 to 1933. Recessions from that time: * 1882-1885 recession (not totally fair; gold standard policies hadn’t had time to cause this) * 1887-1888 recession * 1890-1891 recession * Panic of 1893 * Panic

That’s all oil and gas activity; jet fuel accounts for only a very small fraction of that.

You gave a theory for why it took a decade. You stated the cause as fact.

What’s Russia going to do with that gold? Put it on a train a quarter of the way around the world to Beijing? It is far from trivial to move that kind of stock.

No, that’s an accurate way to look at it. The important thing is the relative movement, not the precise value (the US economy would not be meaningfully different if we cut a zero of the end of every price). Psychological effects can come in

This presents a (relative) vulnerability to cheating. If every computer has the full game state but players aren’t supposed to be able to know some things there is the potential for hacks. The most obvious version of this in StarCraft is ma

How would you re-write the headline? This feels more like a case where people just won’t read it regardless of what’s written.

That’s great in situations with reasonably well-known products. It’s hard to imagine that working for the Apollo LM. Cost-plus contracts have their place, but it’s a pretty niche one for really groundbreaking engineering.

The fps community has exactly the same stereotype of console cod players.

You generally don’t actually have to pay your mortgage - you just lose the house if you don’t (well, and take a hit to your credit score). People can and do walk away from a place when they’re underwater.

The proximity fuses used in WW2 naval AA guns could handle 20000g and were using vacuum tubes. Electronics are more durable than you give them credit for.

If you spread the energy out it will spread in a shape with area proportionate to the square of the distance. You can focus more of that power into a particular area, but the fundamentals here are not particularly negotiable.

You only need to match phase at the connection point, so the phase of the grid in France doesn't really matter (as long as ENTSO-E isn't destroying itself before you do anything). This does get much trickier if you have multiple c

The fuel going into the reactor is also radioactive. It isn’t radioactive waste, but that’s because it isn’t waste. The stuff in a reactor is orders of magnitude more concentrated than what we pull out of the ground. Also yes many of the by

The UK has also explicitly disavowed an EEZ extension based on Rockall (UNCLOS doesn’t allow it). (They do claim territorial seas around it, but that’s 12nmi instead of 200nmi.)

Article 9 doesn’t really mean what it says, at least in practice. If Japan is attacked the state won’t just roll over and die - it’ll try to defend itself (hence the JSDF). You can read it as forbidding offensive war, but if Japan has claim

I think it’s far more likely that Europe would’ve continued down the path it had been on for centuries - war against itself.

It definitely isn’t the same. The square packing in the first picture uses pi/4 ~ 79% of the space; the second uses pi/(2*sqrt(3)) ~ 91% of the space. They don’t bother with smaller secondary batteries because the extra manufactur

Would that really make a difference? Europe gets about 10% of its total energy (ie not just electricity) from Russian gas. I find it hard to believe Germany’s 17 reactors provided that much.

This is also fairly well-known physics. We know what the atmosphere is like at those altitudes and we know what a starlink satellite looks like. Anything that sits around there is going to fall out of orbit pretty fast unless it has active

No. None are space junk and none were made nonfunctional by the storm. 1. The storm caused the atmosphere to expand 2. which increases drag on satellites. 3. The satellites were in safe mode because of the storm, so… 4. some satellites fell

I’m guessing you’ve never looked at US rail in any aspect other than passenger rail? The US runs ~8x the rail freight that the EU does.

No relevant semiconductor fab will be built for less than $100M, no. Each EUV photolithography machine costs $150M alone.
