Joyeux Noel. It’s a French/German/English language film about the Christmas Truce during WW1. Very moving film in my opinion.

If it’s an alpha or beta emitter, sure, you’re probably fine standing near it. But if you find yourself next to a chunk of a gamma emitter, you should probably run away very quickly

So there’s four types of radiation: alpha, beta, gamma, and neutron. When you’re talking about radioactive materials, it’s almost exclusively the first three. In addition to the inherent danger of the object itself, there’s also the danger of radioactive contamination: not making other things radioactive, but shedding bits of themselves as dust and then that dust getting on other things, or getting ingested/inhaled by humans.

Active fission reactions, like what goes on in the core of a nuclear reactor (or perhaps messing around with some plutonium and a screwdriver), produce neutron radiation. Neutrons can make other things radioactive, via a process called “neutron activation”, whereby the neutrons bind to the material and change some of the atoms into radioactive isotopes.

I hope that helps, and feel free to ask me anything else about radiation. I have some education about it thanks to my job, and I’m always happy to help other people understand it more as well.

More or less. The difference is that, if they really wanted to, they could very thoroughly clean the notebook and take most of the contamination off. I’m guessing they won’t because a) It’s a historical artifact and they don’t want to risk damaging it, b) the contamination is so low-level that it’s not dangerous as long as you don’t lick it or something, and/or c) there’s a bit of a shock factor in watching a scientist’s notebook make a Geiger counter freak out.

THE AUDIENCE IS NOW DEAF

…Is your bathroom a swamp?

Isn’t that HAraM

I would recommend Fullmetal Alchemist: Brotherhood and Madoka Magica, as well as Planetes if you’re into sci-fi. Girls Und Panzer is super fun as well.

In 2021, I was riding an Amtrak train when it derailed at 80 mph. Several of the cars, including the one I was in, fell onto their sides and slid a significant distance along the ground. Three people were killed.

After spending the night in a hotel, they arranged for me and several other passengers to get on another train to get us home. I didn’t think much of it, I just wanted to get home, but the moment the train got up to speed I realized I had made a mistake. I spent the entire journey in a state of extreme stress, on the verge of crying. This train (the Empire Builder) is timed so that you get to sit in the diner car and eat dinner while passing through the most scenic part of the trip, the Rocky Mountains of western Montana and northern Idaho. But I didn’t enjoy any of it. I remember staring at my dinner, desperately trying to hold myself together, wincing every time there was a bang or jolt (and for those who’ve never been on an Amtrak train - there are a lot of those).

I had never experienced an anxiety attack before, and based on this experience I never want to have one again. The train got to my home station at about six in the morning, and I didn’t sleep at all.

I blame lazy parents. The message is meant to be “You shouldn’t be picky, you should be thankful that you’re fortunate enough to have access to such quality food. There are people in much worse conditions than you, which much worse food security, who would gladly eat this broccoli/peas/whatever.” But most parents just say “there are starving children in Africa” and leave it at that.

That is the point. You’re basically trying to say “Look how rich I am, I can afford to have all this land dedicated to looking pretty and not being useful for anything else”

Cheetahs are quite a bit more fragile since they’re optimized for speed. Any injury could hamper their ability to hunt, so as a result they’re more skittish and flighty than the other big cats. In zoos they often raise cheetahs alongside dogs, giving them a service animal of sorts so they are calmer around the weird hairless monkeys and don’t get stressed out as much.

The Beast is hotter than his human version ngl

Bender: “I’m 40% chocolate!”

This would have been a much better movie than whatever The Happening was about.

It’s probably for the smell. The plant is rafflesia arnoldii, which smells of rotting meat to attract flies as pollinators.
