Happy to hear :)

I should also say, I think I used the term "greenhouse effect" incorrectly. What I described is how a literal man-made greenhouse works, but "greenhouse effect" refers to a phenomenon on the world scale that is reminiscent of greenhouses, but operates on entirely different principles. For that, the composition of the atmosphere is actually relevant, and the term "greenhouse gases" refers to gases that contribute to warming. For an actual greenhouse though, as I said, it doesn't really matter.

As @FuglyDuck@lemmy.world said, you're building a greenhouse. Nearly all sunlight that gets through the glass will contribute to heating up what's inside, and none of the heat will be able to get out. The major reason for the greenhouse effect is that there's no way for hot air to escape.

Under an open sky, the sun heats up the ground, the ground heats up the air, and the hot air gets blown away by wind and rises through convection, being replaced by colder air from surrounding areas. An equilibrium is reached when the air takes away the same amount of heat per second as the sunlight brings in. But in a greenhouse: the sun heats up the ground, the ground heats up the air, and the air is trapped. It has nowhere to go, so everything continues to get hotter and hotter. The air heats up the glass walls and roof of the greenhouse (the sun helps with that too), until the walls are hot enough to expel all the heat that's brought in by the sun, in the same way as the non-greenhouse ground would. The end result is that the inside of the greenhouse is way hotter than the outside.

Note that this has very little to do with what chemicals the air is made up of. Even if the gas inside the greenhouse has a "sun blocking effect", it would still have to absorb all that energy from the sun, and that heat would still be inside the greenhouse.

I never tried to keep track, but I always assumed each correctly identified lie/truth gets a point, and each mistake gives a point to the other team. Keep in mind that the show gets edited down and you don't see everything that the audience did, while the score probably includes those things you didn't see.

But like, absolutely no one watches this show for the score, so who cares? It might as well be QI's scoring system :)

Yeah, chip fabs are exactly why I think computers would need more time. I'm not super familiar with this, but I'd wager such a factory can only be built using tools and machines that come from other specialized factories, and so on maybe 3 levels down before you get to a relatively rudimentary manufacturing process that can be reasonably achieved within a few years. It would take a lot to get that back up and running.

This brings to mind something David Mitchell said once on Would I Lie To You (British panel show):

In response to Kelvin MacKenzie's claim that the "This Is My" guest had built him a nuclear bunker:

David Mitchell: If there's a nuclear war, I don't want to live. I don't want to come out of a shelter and try to rebuild society. I have no skills. Okay, society is destroyed by a nuclear war, we're basically - we're back to the bronze age...how long is it gonna be before people start pitching panel shows again? It's gonna be at least 2000 years!

Watch it here if you want, it was annoyingly hard to find.

However I don't think David - who is a comedian - is precisely right about how such a war would affect the state of technology. If there are survivors, I don't think we'd really be back to the bronze age. Even if all technology was destroyed (which it wouldn't be), give humans a few decades, we'll have some sort of modern technology back up and running. Maybe not computers, but some certainly some analogue electronics - the knowledge isn't lost. Communications would be one of the first points of focus, so television would follow closely behind.

Damn that actress has range!!

Me too, these cats are synced!

is Obvious Plant still active?

https://en.wikipedia.org/wiki/Roman_dodecahedron

Roman dodecahedra date from the 2nd to 4th centuries AD and their purpose remains unknown. They rarely show signs of wear, and do not have any inscribed numbers or letters.

Emphasis mine.

I think it's much the same purpose that underwear serves for the testicles (and penis). As a man, I honestly can't remember any time I walked around without underwear, but I'm pretty sure it would be worse than with. Things would just flail everywhere.

Other answers about bras are great but I thought the male flip side ought to be mentioned.

nitpick: he's not potus

All true, but it's even worse: sometimes some of the cited facts are plainly wrong. Taking your example, it could be that the midwest actually has the same heart disease statistics as anywhere else. Just because someone told you something confidently doesn't mean it's true. "95% of statistics is made up on the spot".

So maybe "dogs have a much shorter digestive tract" is already wrong? Maybe they have roughly the same length as us? And maybe "[things with parasites] have a much smaller chance of making a dog sick than they do humans" is also wrong? If you care about the truthfulness, you'd have to look that up too. And then you'd have to find that there's causation between the two.

But all that said, I agree with another reply: "It’s a really low-risk bit of information, whether true or false. [...] there’s no harm in taking in low-stakes stuff". So no need to be paranoid about every little tidbit of info, just the things that matter to you.

I was gonna include that in my reply but didn't want to make it into an essay.

Okay but have you actually looked it up to make sure it's true? Never trust facts from random comments, no matter how reasonable they seem to be.

He put them everywhere except on his eyes, where they are known to have the most benefit? (See: Hollywood et al, every spa scene ever, 1800-2024)

Happy to hear you solved it for now. For a more long-term solution, consider investing in an air conditioner. And make sure it also has a heating mode (a.k.a a heat pump), it should cost pretty much the same and is the most efficient way to heat a home in winter.

I wish this was readable besides the first 6

Where is the head? Can't find it in either picture.

Edit: oh, I think I see it in the top one, didn't expect the head and "neck" to be so much smaller than the middle of the body. Still can't quite see it in the bottom picture.

Shortcut for others like me who aren't familiar: https://en.wikipedia.org/wiki/Ted_Kaczynski a.k.a the Unabomber.

Windows' might be complex, but it is NOT graceful. If you have notepad open with unsaved text, then shutdown will never shut down - but nothing on the screen will make this obvious to a non-technical person.
