Oklahoma is attempting to pass a bill that would ban explicit romance novels. Authors, narrators, and sellers could all face fines of up to $100,000 and up to 10 years in jail for each instance.

If you live in OK, call your representative and tell them this bill should not be allowed to pass.

This is likely a test case. Republicans will try to pass it in OK and if it passes other states will likely try to pass similar laws.

In the meantime, get physical copies of books you like. Download those pdfs. Archive your AO3 stories and keep them on a physical hard drive. (Storing those files in the cloud could be problematic in the future as the company managing the cloud service can see what your files are)

Today we officially ended our JS course at school, and I'm gonna miss our lecturer so much 😭 been prepping for tomorrow's assessment all day, i really hope i pass!! And I'm gna meet with some classmates before lunch to rehearse one last time 🌹🌹also lol in the last pic I'm having tea from the tea advent calendar i got from my mom, it was actually so good (yes i put milk in my tea...)

.

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.

A Belousov–Zhabotinsky reaction, or BZ reaction, is one of a class of reactions that serve as a classical example of non-equilibrium thermodynamics, resulting in the establishment of a nonlinear chemical oscillator.
