they did a whoopsie, lead 210 comes from uranium 238. every 220 years radioactivity drops 1000x which means that 200-300 year old lead is mostly fine. copper notably doesn’t have this problem, is dense and is refined to high degree, at scale. it’s good enough to shield most of relatively low energy radiation from that isotope (less than 50kev gammas). couple mm of copper should be plenty for many applications

different tool for a different purpose. water has a large heat of evaporation which is something that allows for more compact turbines

big advantage is that molten salt allows for energy storage for nighttime

hair won’t grow out of scar tissue ever if that’s what you’re asking about

The one we can mine is drawn off together with natural gas, and was produced over geological timescales as product of alpha decay of uranium

New ones, and not all if them, work this way, as in there’s tiny helium condensing unit. Older ones just let it go and require topping up every couple months (guessing by how often helium in NMR is topped up). Also every emergency shutdown invariably blows off all of helium inside

lol this is a question that could only be asked on lemmy. read what you want but more importantly practice

they stood no chance, never knew what hit them

it also happened with tramadol before (different plant)

figuring out other people’s mistakes when trying to replicate their results, closely followed by figuring out my mistakes when trying to replicate my own old results

Adding to that, logistics are such that direct impact will be felt strongest in places like India that rely heavily on Qatari LNG to make fertilizer, but many places have other sources of both gas and fertilizer. Americas, EU, Russia and China will get by because they have their own supply and will be only affected by price increase

without synthetic nitrogen fertilizer there’s only enough reactive nitrogen going around for something like 1-1.5B people. yea mate very sustainable to retvrn to traditional farming and starve 80% of the planet in the process

there was chrome (and firefox probably?) extension that went through your all fb liked pages and unsubscribed from them so that when it’s done timeline is gone entirely. fb went after its dev, removed that extension and banned him forever because it kept people off fb https://www.businessinsider.com/facebook-bans-unfollow-everything-developer-delete-news-feed-2021-10 doing this all manually still worked back then, not sure about today

Facebook’s letter took him by surprise, he said, adding that Unfollow Everything had only 2,500 weekly active users and 10,000 downloads.

“It was definitely growing, but it wasn’t huge,” he said.

“Apart from that I just very much saw it as something that improves the Facebook experience for Facebook users,” he added, saying he got “amazing feedback” from people saying they “were using Facebook in a way that was much healthier for them.”

i bet they have some preferences about contractor

and i told you before that it’s officers (pilots are generally officers) that will be doing aerial bombing, and because large force on ground is prerequisite for situations you’re describing, it’s not going to happen

this multicolored pattern looks like this because thickness of layer of whatever is comparable to light wavelength, mechanism is the same as in oil layers on water being colorful. it didn’t spread from magnet, the layer is thinnest near magnet and becomes thicker near edges, which suggest it might be just dirt/oils that accumulated on it by contact. try wiping it with alcohol or acetone or what have you
