I'll believe it when I see it with my own eyes.

Granted, you now can no longer know the momentum. But it's all you can think about. You eagerly dive deeply into Heisenberg's detractors, desperate to find a solution. For months you learn more about the quantum world than you ever wished to in multiple lifetimes. It starts to bleed over into your everyday life. You start doing the mental calculus to make sure everything you order when eating out comes to $33.13 just so you have an excuse to tip Planck's constant. Your sex life begins to suffer as you try to argue "it's both engorged and flaccid!" As you contort your penis and/or labia majora into a roughly sinusoidal wave function. No one at work cares about your ramblings about how no two customers can share the same account because of the Pauli diversification principle.

But then it happens, you finally understand. Something about the unintuitive has become nothing more than simply logical to you.

At first the understanding was enough.

Then you became restless.

How could you put this knowledge into actionable good for the world?

It starts slowly. You first notice the street lights while driving. Not lit ones turning off, but blinking and burnt ones suddenly start to grow bright as if they were replaced in those femtoseconds it took your neurons to notice the change.

You begin to wonder what else you can possibly manipulate.

While in this magnanimous day dream, you begin to see yourself not entirely unlike the fictional Dr. Manhattan. You see yourself bringing peace and prosperity to the world.

Could you create such a future? Are you capable of resisting the inevitable intoxicating draw that kinda power would grant you?

Your thoughts are suddenly silenced for the first time in years as you are blind sided by a semi truck cause you ran a red light lost in your day dream.

(That is the end, this next part is purely because of my brain rotted Internet addiction. And yes, it is an homage to ShittyMorph)

Your conscious still exist. This isn't the movies where you drift away from your corporeal form, witnessing your last violent moments. No, this is... peaceful. No clouds and pearly gates or fire, brimstone, and demon in the center of a frozen lake. No, this is less theatrical. You experience pastel shades of light blue, green, yellow. They start to form blurry shapes. The indistinct shapes begin to gain form. Things are beginning to sharpen. You see a metal box surrounded by flashing lights. Your thoughts return to your childhood. Like that time in 1998 when The Undertaker threw mankind off of hell in a cell 16 ft through the announcer's table

then you open your eyes after hearing a girls voice.

"Onii-chan! wake up! we have to go to the magical school for the gifted!"

all is right in the world.

The antimatter trap has a allu foil hat.

[–] MBech@feddit.dk 16 points 5 hours ago (2 children)

I love shit like that.

We have this incredibly expensive machine that was made by incredible engineers and scientists who spent an ungodly amount of hours on it. And their solution to some kind of problem with the machine, was to wrap a part in kitchengrade alu-foil, probably from the employee kitchen.

The Voyager spacecrafts had some of their wires wrapped in, cleaned, store bought aluminum foil after a last minute change in the expected environment around Jupiter.

[–] qjkxbmwvz@startrek.website 17 points 4 hours ago* (last edited 4 hours ago) (2 children)

Aluminum foil is very common in physics labs. And a main use for it is "baking"! To get ultra high vacuum (UHV)* you generally need to "bake out" your chamber while you pump down. Foil is used same as with baking food


keep the heat in and evenly distributed on the chamber.

Sadly, it's usually not food grade aluminum foil, as that can contain oils, and oils and vacuum are generally a big no-no.

*Just how good is UHV? Roughly: I live in San Francisco, which is ~7 miles by ~7 miles (~11km). Imagine you raise that by another 7 miles to make a cube. Now, evacuate every last molecule of gas out of it. Now take a family sedan's trunk, fill it with 1 atmosphere of gas, and release that into the 7 mile cube. That's roughly UHV pressure.

How can a metal contain oil?

[–] morbidcactus@lemmy.ca 3 points 2 hours ago* (last edited 2 hours ago)

It'd be coated, but it's from processing, cold rolling metal generates a lot of heat, especially going that thin (thinnest I was around often was ~0.2mm), we'd often temper the material after processing, mainly for surface finish, mill rolls would be sprayed with lubricating coolant really close to what you'd see in use on a milling machine. This was with steel but same principle applies, pretty sure the lubricant we used is also labeled for use on aluminum mills, but you'd use food safe stuff for kitchen foil.

[–] Passerby6497@lemmy.world 13 points 3 hours ago (2 children)

Aluminum foil that's food grade will have coatings on it to assist with food release. I assume that's part of why one side is more shiny than the other.

[–] Krudler@lemmy.world 7 points 3 hours ago

I have always understood the rough side to simply be an outcome of the rolling process.

If I'm wrong I'd love to know!

[–] MonkderVierte@lemmy.zip 3 points 3 hours ago

Ah, it's coated.

[–] notabot@piefed.social 2 points 3 hours ago (1 children)

Thanks for the analogy, that really helps to put it in perspective. I was trying to work out the number of molecules per metre that would leave you with, but either my sense of scales is off kilter or I've got it wrong.

From what I can find, there are approximately 2.5e25 molecules per m^3^ at 1atm. Given an 11km cube has a volume of 1.3e12 m^3^, that gives around 2e13 molecules per m^3^ per m^3^ released. That sounds high, have I got the figures wrong somewhere?

[–] qjkxbmwvz@startrek.website 1 points 2 hours ago

Your numbers seem reasonable


more intuitive for me to work in terms of pressure. Atmosphere is (roughly) 1e3 Torr, good UHV can be around 1e-10, so that's 13 orders of magnitude, which is (roughly) the same difference that you calculated.

[–] OpticalAccount@aussie.zone 6 points 5 hours ago

AGI and simulated reasoning would have figured this out. /s
