PFAS: Last Week Tonight with John Oliver (HBO)

bremnet says...

I hate it when the uneducated try to explain a complex issue and do a piss poor job of it. Is PFAS a problem? Sure. Are ALL PFAS compounds a problem with regards to their toxicity? No. The small molecule species are problematic because of mobility. The polymeric species are stable as fuck, that's why they were invented and why we use them as seals and barrier layers to isolate corrosive liquids and gases, and why we use them in such things as medical implants. The polymers excel because they are inert and largely unreactive. So - are they all bad? No. Are they all good? No. But it's too late - the fuckwits like Oliver have fueled the Emotional Response bus, and society won't stand for outdated concepts like scientific investigation or rational thought. Eight member countries of the EU are presently on track to restrict or ban all PFAS in any form, sweeping all compounds into the same category with no differentiation between a water soluble perfluorinated molecule like perfluorinated PVME and a one million molecular weight PTFE polymer. If it has a -CF2- moiety in it, it's subject to being banned. Good science doesn't matter any more, the knee-jerk fear mongerers are now making the decisions.

Land of Mine Trailer

newtboy says...

Hilarious….you need to ask why someone doesn’t like nazis?…but who said to kill them all? Wasn’t me.
Are you under the mistaken assumption that being a mine defuser is a death sentence, and they all died? Is that what happened in the movie? This was a German plan to have them earn their freedom and not starve to death in POW camps.

I can’t abide Nazis. If you feel the urge to defend nazis, that’s on you, buddy.

So, you’re just trolling then….or are you so dense you don’t see a difference between captive invading murderous soldiers who are around 16 and who were committing a genocide and non combatant children who are 10 and not indoctrinated into violent expansionist racist and murderous fascism? Nazi youth aren’t cub scouts….Jojo Rabbit wasn’t a historically accurate documentary.

If we had not abandoned Vietnam and our soldiers were captured instead, our soldiers there should have been forced to demine Vietnam and Cambodia, including the 15 year olds (the idea that non combatant children be sent there is brain numbingly ludicrous)(Dan Bullock (December 21, 1953 – June 7, 1969) was a United States Marine and the youngest U.S. serviceman killed in action during the Vietnam War, dying at the age of 15. Yes, we use youth soldiers too.).

The mines we left all over those countries have killed and maimed numerous generations, tens of thousands, and continue to do so to this day, and if I’m not mistaken, many POWs did clear mines during captivity. Leaving an active minefield on foreign soil should be a war crime if it isn’t already. It’s definitely targeting the civilian population once the war is over.

Wow. Remind me to never be around your family then. Everyone in my family knew it was wrong to invade and murder our neighbors because we like their stuff and land, and wrong to try to exterminate an entire ethnicity by the time we were 6. If you didn’t know that by 14, you have serious issues. Nazis exterminated the mentally feeble.

The young republicans aren’t a murderous group exterminating Jews, blacks, gays, and anyone not Republican…nazis were. If the young republicans were a murderous group like the nazis, any member should get the death penalty, even the murdering racist 15 year olds….young adults kill just as thoroughly as 35 year olds, their victims were just as terrified and are now just as dead.

The nazis didn’t have a tiny majority through which they controlled German politics, they had a monopoly. Another false equivelent. Christ on a cracker. If Trump had won in 2020, and used the Jan 6 attack on congress as a false pretext to outlaw any opposition to Republicans, taking over completely through violence and intimidation and held and consolidated power for nearly a decade you would be almost there. Holy Ghost on toast!

Are you shitting me. You equate these things, refusing vaccines, creating bad state laws disenfranchising voters, to accepting and participating in genocide. Just fucking wow, buddy. Stretch much? Almighty God on cod!

Old enough to murder, and you do it, you’re an adult. I don’t give a flying fuck if you’re 9. If you know what your doing when you put that gun to a Jews head and say “your children are next, you fucking kike” or a similar slur then pull the trigger, you just became an adult and eligible for the death penalty. We try 12 year olds as adults, but you would shield murderous hitler youth, many of whom turned in their own parents for liquidation, from responsibility from committing genocide among other disgusting atrocities. These kids aren’t Jojo Rabbit. Mother Mary with her cherry!

Besides…as I informed you, it was the German commander who had the idea and gave the order. At least get mad at the right nation.

You said “ but just can't get my head around putting children in a minefield. no matter the justification. that'd be just as bad as anything the nazis could ever do: lose any sense of humanity.”
1) you have lost your ever loving mind if you think a little danger is as bad as anything the nazis could ever do….you simply have no fucking idea what you’re talking about. The atrocities the nazis committed make clearing a minefield they layed look like a nice summer job with a friendly and generous boss by comparison. Try abasination, sewing twins together, seeing how long people can live without skin, raping people to death, melting people alive in acids, starving babies, stomping babies, gassing entire populations, etc. you really climbed so far up on that high horse you can’t see reality anymore. Sweet Zombie Jesus!
2) it was something the nazis did. This was a nazi plan from a nazi officer. Get it straight. The nazis did this, not the allies. That’s what I mean by learn the history instead of getting mad over a story….you are upset over fiction….and defending nazis in your outrage over nothing.

You have a problem. Your position is that nazis shouldn’t have to take any responsibility for their actions…apparently going so far as excusing college age men for fascist, racist genocide because you know some people that age who made some mistakes. (I say that proves my point that just as being older doesn’t mean making better decisions, being younger doesn’t mean you can’t make good decisions. I learned to not hurt other people except in defense in preschool.)

I say if you pick up that gun and march, you’re a soldier and responsible for your actions. If you kill, you’re a killer, no matter your age.

what's beef w/the Hilter youth?

can't abide w/the kill all the baby adolphs vibe. seems extreme. even by WWII standards. just the bare fact that children were used to defuse bombs isn't what one would call kosher. if that was the right of the winning side, one hell of a lot of bombs lying around in Laos and Vietnam - what about sending our Boy Scouts over to take care of the US mess they left?

anyway - not meaning to be mean - at 14 most are not at the level of being correctly called 'idiots'. if you don't know - you just f'n' don't know!

christ on a cracker...know folks who now question what they were thinking joining the Young Republicans - - - AND THEY WERE OF COLLEGE AGE!!!

what is freaky is the line "If the majority of Germans weren't complicit, the Nazis would have never come to power."

2016 mean anything? and that's the MINORITY of Americans!

christ on a cracker...what's the situation on the COVID vaccines? on voting bills? on any f'n' bill or issue in this land? the MINORITY is having their day keeping the rest in the dark.
[2nd Amendment but screw the other 26...or 24...cause 21 cancels 18 = 0]

as you said "History isn't nearly as cut and dry as it's presented, neither are war crimes"
as he said, "And as with most things, particularly in times of war, it's complicated."
but just can't get my head around putting children in a minefield. no matter the justification. that'd be just as bad as anything the nazis could ever do: lose any sense of humanity.

How Women Are Written In Sci-Fi Movies

I stand corrected. I had thought it started on Amped in the 80's, but Wiki says Liquid Television in the 90 s.

An exception proves the rule, too many exceptions disprove the rule. Yes, it was an outlier, most great things are.

i would say aeon flux is also an exception for precisely the reasons you gave. it was also wildly outside the norms at the time and now.

Making Spherical Tanks Through Explosive Hydroforming

eric3579 says...

From YouTube videos description..

Explosive hydroforming, also known as HERF (High Energy Rate Forming) or exploform, is a striking alternative to the more traditional process of metal hydroforming. Unlike this older method, which shapes metal using pressurized hydraulic fluid pumped into a forming chamber, HERF techniques utilize an explosive charge to create the necessary pressure. Although the charge is relatively small, it is capable of generating enough force to mold the associated metal into the die.

The explosive charge is typically positioned at a specific distance from the workpiece, and both are immersed in fluid, usually hydraulic fluid or simple water. Certain facilities may also use oil, gelatin, liquid salts, or regular air as the transmission medium. However, water is the most commonly used medium as it is the least expensive, excellent for creating uniform peak pressure, and readily available. Once the charge and workpiece are properly positioned, the charge is detonated, pressing the workpiece into a die. The part is then removed and the process is repeated if necessary.

Explosive Hydroforming Methods
Explosive hydroforming techniques fall into two basic categories. Although both methods function according to the same general principles, they rely on very different placement of the explosive charge within the forming chamber.

Standoff Method: With the Standoff Method, the explosive charge is used in conjunction with an intervening medium. In most hydroforming applications, the intervening material is typically water, oil, or air. The required deformation level dictates how far the explosive charge is placed from the piece of metal to be formed. When the charge detonates, the ensuing force is transmitted through the fluid and pressures the metal into the die. Detonations used in the Standoff Method can often reach several thousand pounds per square inch (psi).

Contact Method: In the Contact Method, an explosive charge is placed in direct contact with the forming metal. This process generates far more pressure than the more conventional Standoff Method. By placing the explosive charge in close proximity to the surface material, the detonation can result in as much as several million psi.

Biden Has A Lot To Boast About In New Covid Relief Bill

StukaFox says...

Bob, as much as this'll surprise you, I totally agree with what you're saying. The distribution of the stimulus money to couples making up to $150,000 is friggen ridiculous -- and I'm in that category. I will do what I did with the last two checks: give to local charities helping the homeless and communities of color (as much as I hate that term).

The worst part of this is that it sets up a liquidity trap. The Fed can't reduce buying crap debt (that BBB dogshit is at 4% should terrify anyone who understands how debt and the rating agencies work), nor can they allow rates to rise (thus totally screwing responsible savers). This is the cusp of a financial disaster that blew past 1929 on 9/17/19 and is now approaching the cataclysm of the South Seas Company collapsing. As far as I can see, this is a total melt-up in the markets because there's no stable returns and everyone is now in speculation mode.

Were it my call, I would scale the money along income (or non-income) lines: $10k for the lowest incomes, sliding scale from there. I'd also set up government-backed savings accounts that pay 10% for those people and only those people. I'd also pay off/down student debt along the same income scales.

I do not begrudge the wealthy for their wealth. But capitalism can't be a winner-take-all system. We live in a society, and society will always have winners and losers. The least we can do is ease the burden for those at the bottom by taking some from the top. I'm tired of the homeless camps and mentally-ill people wandering the streets of Seattle. They are the least of us and thus should be the ones who get the most help.

Brokers MANIPULATING MARKET to save hedge fund billionaires

StukaFox says...

Sorry to be the little grey raincloud on this Hate The Hedges party, but you might want to understand the implications of what just happened

Y'know that fund that's getting all attention, Melvin Capital? Yeah, fuck them, right? Fuckin' shorters all shortin' and shit -- they played, they paid!

There's a reason they were bailed out and with all due haste.

Here's the issue: they were VERY good at the shorting game. So good that they actually had to turn away business. They made money like horses makes shit. When clients couldn't get in at Melvin, they went elsewhere. That opened the door to a lot of other firms basically mirroring exactly what MC was doing, which included shorting the fuck outta GME.

Fuck those guys too, right? It's their money, so why should I care?

Let's go back a few year, shall we, to the glorious chapter in finance and economics that was the 2008 Crash. Remember when Paulson lost his shit because he realized that in about 36 hours, the basic system called Western Capitalism was going to shit the bed; the bedroom; the whole house and pretty much every surface above the ocean within a planetary radius? This is sorta like that. Only worse.

The thing about short squeezes is that the losses can be infinite, and that's exactly why WallStreetBets did what they did. They knew if they bought and held -- diamond hands -- the stock would have to rise as the shorters had to cover their bets. Melvin Capital and a shit-ton of other, smaller firms had to do that and ran out of liquidity long before GME was even at $50. For every share of stock they shorted, they need to cough up another share at a higher value -- and they HAD to actually have the higher-priced share.

And here's where things get VERY ugly.

Shorting GME was such a sure thing that a huge number of shorts were placed. In fact, more shares of GME were shorted than actually existed. Oops. But hey, SURE THING, BABY and what's the worst that can happen?

Yeeeah, y'see where this is going now?

So these firms, not only are they broke, they don't have the shares, either. They need to come up with shares, pronto, at any price, because contractual obligations are a motherfucker in the finance world. But again, more shorts than there are shares and the people who have the shares, WSB and 4chan's /biz/, aren't letting them go. The longer they hold, the higher the price will go as short after short faces having to cough up the shares they borrowed.

A lot of people are about to lose a LOT of money -- the kinda losses that have so many zeros attached that looking at the number bores the eyes.

Back to 2008: the reason the whole world almost started Mad Max LARPing back then is that a narrow number of highly-important financial institutions were a wee bit thin on liquidity because they were having to pay it out by the boatload. That's bad. What would be better is if risk were more distributed, and how could that little plan POSSIBLY go wrong? Maybe a Black Swan event involving a huge amount of money that needs to be paid out by all of them due to this annoying bird.

That's where we are now, but no one even remotely knows what that figure is going to be. Again, (potentially) infinite losses multiplied by 150% times the number of shares actually available, multiplied by the dogshit risk factor on the loans and the leveraged payouts -- your best case scenario might be a loss of about $500 billion. Someone has to come up with that money, be it the Fed or other banks/investors, but that latter group has to come up with the money themselves, which is generally accomplished by selling profitable holdings. We all know what happens when a lot of people have to sell, right?

I always wanted to live in interesting times, thus proving what an utter fuckwit I am.

Allassonic/Hot Chocolate Effect

Allassonic/Hot Chocolate Effect

newtboy says...

Works with most hot liquids with powders, I think I first noticed it in a mug of instant hot cider......

https://en.m.wikipedia.org/wiki/Hot_chocolate_effect

The hot chocolate effect, also known as the allassonic effect, is a phenomenon of wave mechanics first documented in 1982 by Frank Crawford, where the pitch heard from tapping a cup of hot liquid rises after the addition of a soluble powder. It was first observed in the making of hot chocolate or instant coffee, but also occurs in other situations such as adding salt to supersaturated hot water or cold beer. Recent research has found many more substances which create the effect, even in initially non-supersaturated liquids.
It can be observed by pouring hot milk into a mug, stirring in chocolate powder, and tapping the bottom of the mug with a spoon while the milk is still in motion. The pitch of the taps will increase progressively with no relation to the speed or force of tapping. Subsequent stirring of the same solution (without adding more chocolate powder) will gradually decrease the pitch again, followed by another increase. This process can be repeated a number of times, until equilibrium has been reached. Upon initial stirring, entrained gas bubbles reduce the speed of sound in the liquid, lowering the frequency. As the bubbles clear, sound travels faster in the liquid and the frequency increases

Antifa thugs behind Andy Ngo disgusting bashing

newtboy says...

No, he's a liar plain and simple and we know it.

That means anything he claims is quite suspect and not to be believed, just like this "attack" he staged.

He may have been attacked, that's what he was looking for, but no one cares because 1) he went there looking for it and 2) his injuries are self reported so quite suspect and 3)he's a known liar who just as likely hurt himself (if he was hurt at all) in order to blame the milkshake throwers.

I watched the video, I saw no "combat clubs". I saw plenty of totally liquid milk shakes with no powder or clumps, so no cement, and the close-up thumbnail that confirms that.

I also saw a known liar and rabble rouser intentionally picking a fight with a known violent gang who hoped to get attacked on camera so he could condemn them, and you bought it hook line and sinker. I think you know it.

Odd, you aren't as upset by the lack of coverage of all the innocent people violently attacked by Patriot Prayer gangs, and there are plenty of them.
