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.

Helium exists in equilibrium amounts in the atmosphere just like other noble gases. It's present in higher concentrations than krypton or xenon (or methane, for that matter).

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.

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).

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.

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.

It does gently caress off in to space, but slowly enough that it still makes up 0.05% of the atmosphere

Edit:

Wikipedia, the free encyclopedia that anyone can vandalise posted:

Atmospheric escape of hydrogen on Earth is due to charge exchange escape (~60–90%), Jeans escape (~10–40%), and polar wind escape (~10–15%), currently losing about 3 kg/s of hydrogen. The Earth additionally loses approximately 50 g/s of helium primarily through polar wind escape.

Those kinda ends are very heavy and also it's on the back of the load, which is exactly where you don't want heavy loads.

Yes. This is 100% caused by not securing the load. Every crane truck is going to have a means of securing that with a chain or strap.

I loved jaws so much. When I got my dental implants done I told them I wanted to be able to bite through steel cables just like him.

Also I wonder if the crane started swinging because of a turn or just harmonic motion going down the highway
