hi show me ur cats the one in ur pfp looks neurodivergent is it yours and are both of your cats neurodivergent

*passes you the mic*

YESSS MY PFP IS ONE OF MY CATS, Bonnie (my pfp) is the definition of adhd

And the other one (Milou) is the definition of autism

As you can see he only likes to sleep on that specific blanket, and Bonnie sleeps wherever he wants

Okay so a guy in my solid state physics class was telling us about this muon scanning startup he worked at, GScan, and I'm going insane. I don't work there and I have no stake in the company, financial or otherwise, I just need to tell you about it.

Muons are short-lived subatomic particles, same charge as an electron but ~200 times more massive. On Earth, they're produced by cosmic rays colliding with the upper atmosphere, and they hit the ground at a rate of about ten thousand per minute per square meter.

They're moving extremely fast at ground level, like 0.99 c. So they careen right through matter, deflecting only very slightly around heavy atomic nuclei – they'll penetrate like a hundred meters into solid rock.

What do you do with this continuous shower of deep-penetrating charged particles, constantly blanketing every square inch of the Earth's surface?

The classic thing is use them to image the inside of massive structures, like we use x-rays to look inside living tissue – except instead of generating them yourself, you just use atmospheric muons. Muon archeology is a whole thing, they've used it to find hidden chambers in pyramids and stuff. Neat!

But this one Estonian company is doing some crazy bullshit and I love it.

Sandwich anything between a pair of portable muon detectors and get full 3D imaging of the interior, with sub-millimeter accuracy, by tracking the minute deflection of muons between them. Samples that are WAY too thick for x-rays, made of literally anything. Just put some muon detectors on some two by fours in a warehouse and call it a day.

You can just. Image anything??? Anything you want?? Completely passively!! Just detectors! No particle source! Put them anywhere. The detectors themselves are a mature technology, the company's tech is in the algorithms they use to get this level of spatial and elemental resolution.

You can detect failures inside cable-reinforced concrete bridges without cutting open the bridges.

Decommissioned Soviet nuclear submarine filled with concrete, with no drawings or documentation, that may or may not have spent fuel canisters in it? And you need to cut it up for storage? Just look at the muons.

One of the wackiest ideas is to put one detector under your bed and one on the ceiling, so you get a full 3D scan of your body every night, passively. I want one.

Cosmic-ray based solutions for 3D imaging. GScan redefines the boundaries of 3D scanning with Muon Flux Technology (MFT) detectors. Unparall

And another thing, muon detectors are so easy to get a quick first draft of ur detector.

The first time I made a scintillator and SiPM based muon detector, I didnt know what I was doing but I got it working after 2 hours. (Optimization and calibration took 2 months but thats beside the point)

And whats good about SiPM based muon detectors is that they only need 60V! However in the images that i see here it seems like the detectors are pretty large so maybe they used PMTs which need a higher operating voltage (like 1500V) but idk. Ive read the paper about the egyptian piramid scanning but i forgor what they used.

There also exist other methods next to scintillators, like gaseous detectors for muon detectors but those are harder to build (I will help building the new gas muon detectors for CERN next month😎).

Blackout poetry exists on a dual axis from "banal" to "insightful" on the input side and "kind of deep" to "incredibly fucking dumb" on the output side, and while taking something banal and producing something kind of deep is well and fine, for my money taking something insightful and rendering it incredibly fucking dumb is where the real art is.

I’m really fucking proud of this, not sure how I pulled it off but I’m not going to complain.

To anon that asked:

It's referenced from Dirac in this photo!

i want this photo on my blog again #sorry

i just love it so much

i like the way they're awkwardly staring at each other

I have this cut out and taped to my wall with some other random shit and every time I fucking see it I get lowkey pissed because no fucking drawing I've made since then has managed to be as good. This is objectively good art. And I have not managed that whatsoever since.

Spin the wheel. Now, imagine you're on a first date with someone who says they`re a [result]. How does this affect the odds of a second date?

100% guarantee I'll want a second date

It's significantly more likely

The odds don't change

It's significantly less likely

There wont be a second date. Absolutely not

Hello, Tumblr user. Here's a non-binary character who uses they/them. Their ASAB isn't relevant at all for the story and everyone regardless of relationship uses they/them for them and they're trans. Your challenge will be to not try to sniff out their ASAB. Go---- oh you're already telling other people who don't agree with you they're wrong and bigoted for hcing it different from you. Okay.

you ever think about how mr beast is real life monokuma

I believe Mr Beast is just itching for the day he can do a real death game. I think he constantly pitches it to his team and they just keep going "not yet, but soon"
