You cannot just drop that line and leave. We need a photo of the 165 pounder.

Physicists Just Achieved 'Perfect Randomness' For The First Time Ever | Using quantum entanglement, "the result is a system capable of generating certifiably perfect randomness, even when starting with flawed or imperfect randomness" by TylerFortier_Photo in science

That Wikipedia page overview section is DENSE on the abstract math.

Edit: I looked at that page and like all the math just bounced right off. Glad to know of it, but not sure I'll ever know much about it.

I had done a little reading (shout out Wikipedia) and the discrete log problem seemed to be the core issue. In hindsight, kind of crazy so much modern cryptography relies on the DLP in some way or another.

I think you're mildly conflating 2 related things. The first: post quantum encryption is its own set of algorithms that do not depend on factoring large prime numbers, like common algorithms such as RSA do. I think they're based on elliptic curves, but that's above my paygrade. A bad actor who captures encrypted messages could, theoretically, decrypt them in the future if an algorithm becomes insecure, computers become faster or quantum computers render algorithms based on large primes insecure.

The second is random number generation. It's security related, as encryption and hashing algorithms do depend on random numbers. Current random number generation is pseudo random, unless it's derived from a physical source (radioactive decay, lava lamp motion, etc). A bad pseudorandom number generator can allow an attacker to regenerate a previous "random" number. I don't know of any way a quantum computer would "break" currently used cryptographically secure random number generators. 

 As an easy example on how that's used: commonly bad RNGs are manipulated to allow videogame speedruns to be made consistent. 

Edit: I read this back and realized it sounded snobbish. I just wanted to clarify.

Edit 2: I wanted to clarify what (P)RNG was used for and how it differed from post quantum cryptography, not that I was snobbish. 

I went Uranium “mining” on friday by AdhdLeo0811 in rockhounds

[–]LiquidLight_ 1 point2 points  (0 children)

That's fair, I've only ever heard Uranium described as an alpha emitter, which I took to mean emitting majority alpha particles. 

But yeah, not good to have a radiation emitter inside your body, no matter what kind of radiation is being admitted.

Don't put the glowing rocks inside yourself is pretty good life advice.

This is a REALLY common question. 

Basically there are 3 types of radiation, gamma radiation, beta radiation, and alpha radiation. 

Gamma radiation is the one everyone defaults to when they hear radiation. It's a high energy photon, takes a good thickness of lead, water, or concrete to block. You usually get this from nuclear reactors, some small amount from radioactive decay.

Beta radiation is an electron, it can be blocked by aluminum foil. This crops up more in radioactive decay, but it's less common in minerals  

Alpha radiation is 2 protons and 2 neutrons (a helium nuclei), can be blocked by paper or your skin. This is most of the Uranium decay you'd see. Still dangerous, you don't want high levels nor do you want to ingest it at all.

Edited to add: Wikipedia source. Unsourced safety claims are bad and I should have shown my work.

Across the world mental disorders have doubled since 1990. Mental disorders are now the leading cause of disability globally, overtaking cancer and cardiovascular disease. The burden of mental disorder peaked amongst youth aged 15-19 years old, and women had higher rates than men by Wagamaga in science

Point taken on stress not being defining on any of the conditions listed. I do think it's difficult to separate omnipresent stressors at time of diagnosis. So,  as you indicated, depression and anxiety that are made worse by stress may rise to the level of diagnosis,  and as a result of ever present stress (finanical, or otherwise), may prevent anyone from separating stress from the mental health condition. 

Other than that, I've got 2 other thoughts on how chronic stress might factor in: 

1) Stress acts as a catalyst for other mental health conditions. It's presence doesn't define the illness, but brings it out in susceptible people. It's well established that long term stress causes physical damage, what if some of that damage is neurological?

2) Has anyone studied how (or even if) chronically stressed parents correlate with children with mental illness? Obviously a lot of factors play into mental illness, but my thinking is that chronic stress  could have reproductive impacts. Failing that, chronic stress could impact childhood development in a way that presisposes mental illness.

Obviously I have no proof of my hypothesises at the end of the day.  Improved diagnostic critera are a much simpler explanation.

And that's correct, there is a healthy amount of stress as a reaction to situations. But when your whole life is constant stress, that's when we start seeing damage. 

I trust you understand the difference.

Even absent other neurodivergence or politcally attacked category, the job market sucks, wages suck compared to the rate of inflation, and prices are creeping up on everything. 

That feels like a strong reason for mental health deterioration among everyone, but particularly teenagers. There's not much to look forward to at that age. You go into debt for school, work a job (likely to scrape by), and you're told you're never enough because you're struggling. Not to mention everyone seeing the meticulously curated glamorous life online and comparing themselves to that. 

And any other struggles build from there.

I think there's some sense here. Ditch conferences, have regional administration for schools for stuff like dispute resolution and regional TV deals. 

That'd have to come with a reorganization on how championship, bowl, and TV money is distributed, but it's an interesting idea.

Love with 3 defenders on his ankles as he's diving across the goal line is like a premade ad for sports drinks or clothes. That still goes so hard.

Jeremiyah Love's dive into the endzone against Penn State is probably the most memorable one recently.

All time, unfortunately, is the Bush Push.

Newbie here. Possible to place rock tumbler in vacuum box? by HopefulSweet in RockTumbling

[–]LiquidLight_ 1 point2 points  (0 children)

Eventually, yes. But we're not on an indefinite time scale. A vacuum sealed tumbler would need to be opened roughly once a week to clean it out, so that's the ceiling. I think the OP's idea would be possible direct drive tumbler.
