also: you can calculate the carnot cycle efficiency of a solar cell as if it was a classical heat-power-machine, even though it has no visible moving parts.

the reason why this works and yields realistic results is because the basic principles of thermodynamics stay the same no matter if you are working with steam, combustion gasses or photons and electron gas inside a semiconductor.

The current fertility rate for France in 2024 is 1.847 births per woman, a 0.05% decline from 2023

Sounds about right. Western and Central Europe is aging rapidly. I doubt Paris is much of an exception to that rule.

that sounds almost exactly like the Reichsbürger in Germany. They also claim the current German state is actually just a corporation and the laws of the German empire are somehow still applicable. They also create their own passports. And of course they are deeply interconnected with Neo-nazis.

UTF-32 would also be an interesting target. i believe python3 uses that as its internal format for strings.

oh i must have missed a few orders of magnitude there. 6Mt of helium is a ridiculous amount though ... what is all that used for? according to WA that is about the water volume of the three gorges dam at STP

Edit: just read the report, wow, more than a quarter of all the helium is used just for "breathing mixes" which i assume means its for scuba diving.

from the wiki article on Helium:

an estimated 3000 metric tons of helium are generated per year throughout the lithosphere.

I think the main issue here is not that we are loosing helium on a planetary scale but that the easy to reach helium from gas wells is wasted. We will never run out of helium at our current rate of consumption before the sun goes nova, if we consider all sources on earth, but it will get a lot more expensive and the supply will get less steady.

vasistas

its real, though not necessarily the type of window that you described. also exists in Turkish. i have a Turkish colleague who was very proud to explain the origin of that word to us in Germany :D .
