Mister Speaker posted:Curious, is there a particular reason Russia has a monopoly on helium? Helium doesn't really exist in the atmosphere - it's so light that it basically just floats out into space. It also doesn't react with anything, so it's not like hydrogen where there's an endless supply bound up in more stable and down-to-earth materials (like water) that you could produce it from. All the helium we have access to basically comes from natural gas wells - the same structures that trap fuel gases underground also trap helium. But since we don't use zeppelins any more, there's not a huge industrial demand for helium (and until recently, the United States was selling down the national helium reserve, depressing prices even further), so most natural gas wells don't bother with the (expensive) infrastructure to collect and store helium for sale.

It's produced via the radioactive decay of stuff like uranium and thorium which altogether make up a significant proportion of the Earth. There's effectively an endless supply of it, there's just not an endless supply of it at prices as low as when we were dumping the helium reserve. If we stopped getting it from natural gas wells tomorrow, we'd start getting it from air liquefaction, just like we get neon. quote:But since we don't use zeppelins any more, there's not a huge industrial demand for helium (and until recently, the United States was selling down the national helium reserve, depressing prices even further), so most natural gas wells don't bother with the (expensive) infrastructure to collect and store helium for sale. And of the ones that do, several have gone down for reasons of repair, or war (redirecting natural gas to Europe to make up for the shortfall from Russia, for example).

Powered Descent posted:I don't honestly know. I don't recall ever putting refrigerator magnets on my face to test that, when I had braces as a teenager. Most metal used in people is not ferromagnetic and can go near an MRI without issue. It will still cause artifacts on the scan which uses radio waves to generate the image. A good MRI tech would screen your face with a metal detector to make sure before you enter the can room. Not all MRI techs are good.

McCracAttack posted:Are they made of magnetic metal? They don't even need to be magnetic. You can take a gold wedding ring into an MRI and it'll do weird poo poo due to induced currents from the gradient coils, or couple to the RF sources and heat up. Same physics that let you crush a beer can with a coil of wire and a big capacitor despite it being aluminum, or set your bag of popcorn on fire in the microwave because you forgot to remove the staple. Even pure gold fillings can end up with issues due to heating the gently caress up inside your mouth because you're inside the 10 million dollar science coffin. If they're made of magnetic metal, they're gonna promptly and violently introduce themselves to the nearest wall of the magnet housing. A paperclip can wedge itself to the housing of an MRI with something like 40 pounds of force, and the force of the pull is proportional to the size and mass of the object. Buttplug MRI man, assuming it's real, probably had his toy shift around in his guts with the force of anywhere from 500 to 1500 pounds, which would do similar things to his colon as that horse did to Mr Hands.

I have permanent wires on the back of my front teeth and had an MRI and they're still there (teeth and wires) so I guess the answer is "it's anecdotally fine".

Is the driver swerving like that for laughs or are the crane hook weights just that heavy to cause that?
