> "As of early September 2022, 32 of France's 56 nuclear reactors were shut down" This is cherry picking. Look at the 10 years, or even lifetime, average availability. It's 90 or 95%. The reason for this bad number is

Nice auto pilot! Very basic, but works well enough. In the real world, you would derive physics equations (acceleration -> velocity -> position), add constraints and then solve everything to obtain an optimal trajectory (mostly in ter

Please look at yearly averages to avoid cherry picking. Maintenance is planned every autumn to make sure that all the nuclear plants work when they are needed, ie. during winter.

It is not exactly increasing enrichment capacity, it seems it's more complicated than than. From https://twitter.com/TristanKamin/status/1579828412474351616 , "UTS" is basically a tradeoff between en

> because of massive defects or barely producing due to a lack of cooling water This is false, and not the reason for the (currently) low load factor of nuclear. Most reactors are off for maintenance, like they are each year in autumn, i

> nuclear is demonstrably not working well You are jumping to this conclusion way to fast. First, you are cherry picking: you should look at the yearly load factor, not a random day and time of the year when it supports your argument. An

Small precision, because the title of the article is wrong: JWST is a joint NASA–ESA–CSA project and is actually launched by ESA.

Hey! Jumping in, because I'm learning German: do you have other suggestions appart from MaiLab?

TL;DR: eating 1 kg of phosphogypsum each day yields 36 mSv/year. Conclusion: very very far from life-threatening ; nobody is going to die or get cancer because of this. Oh God. This is Fukushima radioactive waters all again. I'm

This sounds very illegal. From what I know, in France the notice period is 1 month if it is "meublé", or 3 months if the appartment is empty. Edit: actually, I just checked and that's for tenants. If the landlord wants to bre

> Afaik originally the life-span for most reactors of that kind was 40 years That's a lie, or at least an unprecise statement, mostly shared by the anti-nuclear who are looking for a reason to close reactors. In France, reactors wer

I am a (aerospace) software engineer. I you wonder what trajectory the Apollo missions followed to go to the Moon, you can read my article about it: https://blog.nodraak.fr/2019/06/free-return-trajectory-1-fly...

While I dont think it is specific to a region, it is probably specific to an age: verlan is quite used among late teens / young adults, while Javanais is more used by childs / young teens. I used to speak Javanais with my sisters

It's not only about altitude ( going to space is easy), it's also about horizontal velocity ( staying in space is hard: 8 km/sec is a lot). I dont recall the exact number, but I think that altitude is 50% of the energy, the

Murder? Do you have a source for that? To my knowledge nobody died of radiation at Fukushima.

> Is a fact that radioactivity kills people That is false. Or at least very inaccurate. High levels of radioactivity kills people. In Europe we receive ~5 mS per year, ~10 in the US. Pilots and radiography doctors are at ~20-50 mS&#x2F

To deorbit a satellite, you need an antenna (to receive the command), electricity (working solar panel / battery), working on board computer, fuel, correct attitude determination. So basically you need a full working satellite. As soon
