Koi Fish Skyscraper in a Koi Pond

S3ZHUR says...

This is gonna be long but please bare with me.

The pressure below the surface of any body of liquid is equal to the density of the liquid multiplied by the depth below the surface, multiplied by the acceleration due to gravity. The result is a quantity in pascals, or newtons per meter squared. To this number we add the pressure due to the atmosphere, 101325 pascals; the sum of the two is the pressure experienced by the koi.

The column of water is suspended by virtue of the vacuum that exists at the top of the column, ie. There is no atmospheric pressure pushing down on the column and hence you can 'support' up to 101325 pascals of water pressure within the column before water in the skyscraper would begin to displace water within the pond (this is how simple barometers work). Remember that the pond is under 101325 pascals of pressure, and that as long the pressure within the column is the same as outside there will be no net flow of water. For instance, the maximum possible height of the column would be 10.3 meters (101325/[9.8*1000]).

What all this means is that the water within the column is at a LOWER pressure (and getting increasingly lower towards the top) than the water within the rest of the pond; in a 10.3 meter column the pressure at the top would be 101325 pascals less than at the surface of the pond. So, if a fish looking for food or perhaps increased warmth were to come across the column and swim inside it they would find themselves at a lower pressure than they are designed for. Their air bladders would swell in the decreased pressure, this would in turn lower the density of the fish consequently increasing they're buoyancy forcing them higher into even lower pressure water, eventually trapping them at the top. As more fish find the tower, more fish are forced to the top where they begin to compete for the rapidly dwindling oxygen supply. Furthermore, freshly oxygenated water would not reach the top of the tower as the water flow would be severely limited through such a constriction. In the third clip you can see what MAY be the fish gasping for air.

In conclusion it seems likely that our German friend has succeeded in creating a fascinating death trap for his fish, and I'd bet that he got up the next morning to find that he had killed thousands of dollars worth of koi. This would also explain why we/I have never seen this design before. Of course, I am assuming that the fish lack the necessary muscle power to get themselves out of this situation, which they may well have, but the number of fish so close to one another seems odd to me. I would of thought that if they could easily get out of the column then they would, if simply to find a less crowded location.
Tl;dr IT'S A TRAP

EDIT: I guess I lost that bet as it would seem that the fish do have the necessary oomph to escape. Though I wish no ill will towards our fishy friends I would still be morbidly curious to see the effects of a ten meter tower.

Not really, it would be inverted. The pressure would be negative, causing the swim bladders to swell beyond their normal size and the air within to be more buoyant.

>> ^Drachen_Jager:
I guess the water pressure accounts for them all congregating at the top. Question is, can they get out again? I can't imagine their swim bladders evolved to be able to deal with a situation like that.

Actually, the pressure differential is the same barely different as a pond the same distance deep.

somebody failed physics 101.
geez! the pressure in the column is exactly the same as in the pond!

Glad you realize that human nature is flawed; the "sheriffs" who are supposedly going to clean up the town are also flawed and corruptible, and the last gang anyone should expect to "fix" the excesses of capitalism are anti-capitalists.

BTW, isn't Obama's biggest campaign donor(s) Wall Street?

Liberalism eats its own tail when it demands a government so huge it can supposedly stop any kind of perceived corruption. It ends up a cure worse than the disease.

This idiot thinks these protesters are organized as a scheme by a political party? - These protesters are a spontaneous uprising.

This is a very VERY Good point and I don't mean that sarcastically. Humans are fucked up, they do fucked up things when you make it EASY for them to do it that way. That's the point of the protest...to have the People oversee the corporations and check their power rather than corporations controlling everything. If the country was more democratic these private tyrannies wouldn't BE ABLE to do things of this sort. So the entire point of these protests is to try and bring a big bright light over the fact that Humans will be Humans...check their fucking power.
Thank you QM you made the best Lefty point in this comment section without knowing it.

As we gather together in solidarity to express a feeling of mass injustice, we must not lose sight of what brought us together. We write so that all people who feel wronged by the corporate forces of the world can know that we are your allies.

As one people, united, we acknowledge the reality: that the future of the human race requires the cooperation of its members; that our system must protect our rights, and upon corruption of that system, it is up to the individuals to protect their own rights, and those of their neighbors; that a democratic government derives its just power from the people, but corporations do not seek consent to extract wealth from the people and the Earth; and that no true democracy is attainable when the process is determined by economic power. We come to you at a time when corporations, which place profit over people, self-interest over justice, and oppression over equality, run our governments. We have peaceably assembled here, as is our right, to let these facts be known.

They have taken our houses through an illegal foreclosure process, despite not having the original mortgage.
They have taken bailouts from taxpayers with impunity, and continue to give Executives exorbitant bonuses.
They have perpetuated inequality and discrimination in the workplace based on age, the color of one’s skin, sex, gender identity and sexual orientation.
They have poisoned the food supply through negligence, and undermined the farming system through monopolization.
They have profited off of the torture, confinement, and cruel treatment of countless animals, and actively hide these practices.
They have continuously sought to strip employees of the right to negotiate for better pay and safer working conditions.
They have held students hostage with tens of thousands of dollars of debt on education, which is itself a human right.
They have consistently outsourced labor and used that outsourcing as leverage to cut workers’ healthcare and pay.
They have influenced the courts to achieve the same rights as people, with none of the culpability or responsibility.
They have spent millions of dollars on legal teams that look for ways to get them out of contracts in regards to health insurance.
They have sold our privacy as a commodity.
They have used the military and police force to prevent freedom of the press. They have deliberately declined to recall faulty products endangering lives in pursuit of profit.
They determine economic policy, despite the catastrophic failures their policies have produced and continue to produce.
They have donated large sums of money to politicians, who are responsible for regulating them.
They continue to block alternate forms of energy to keep us dependent on oil.
They continue to block generic forms of medicine that could save people’s lives or provide relief in order to protect investments that have already turned a substantial profit.
They have purposely covered up oil spills, accidents, faulty bookkeeping, and inactive ingredients in pursuit of profit.
They purposefully keep people misinformed and fearful through their control of the media.
They have accepted private contracts to murder prisoners even when presented with serious doubts about their guilt.
They have perpetuated colonialism at home and abroad. They have participated in the torture and murder of innocent civilians overseas.
They continue to create weapons of mass destruction in order to receive government contracts. *

To the people of the world,

We, the New York City General Assembly occupying Wall Street in Liberty Square, urge you to assert your power.

Exercise your right to peaceably assemble; occupy public space; create a process to address the problems we face, and generate solutions accessible to everyone.

To all communities that take action and form groups in the spirit of direct democracy, we offer support, documentation, and all of the resources at our disposal.

Join us and make your voices heard!

To clarify, I'm one of those people on the left who knows that the "Tea Party" protests have been happening for years -- a lot longer than Obama's been President anyways.

What was fake was their explosion post-2009. All of a sudden, the big GOP money groups and media outlets pimped and fluffed the movement, and changed it from a movement largely centered on a Ron Paul-style platform, to a totally straight down the line GOP platform, social issues and all.

What I was mad about was that the media only "discovered" them after they'd been turned into a wholly owned subsidiary of the Republican party, and continued to insist they were some sort of brand new, spontaneous, authentic movement, long past the point where it was super obvious that they were astroturf.

Now here's my prediction about the Occupy Wall Street group -- starting today, the media will go back to ignoring them, on the grounds that now they're just a front for Unions and Democratic political organizations. In other words, at the first signs that this protest might align with a broader liberal agenda, they'll go back to dismissing them, either for being astroturf, or simply because they look like dirty fucking hippies.

And yes, this is one of those predictions I hope I'm wrong about, but I kinda doubt it.

Lefty voices don't think the Tea Party is Fox/Murdoch-sponsored: the belief if that Fox and the Tea Party itself are funded by corporations (that top 1% everyone's talking about.) The middle class wants a more responsible system that doesn't simply reward the rich by allowing them to get discounts based on their purchasing power, while the small startup or poor individual is forced into debt for not having the capital in the first place. Go watch Zeitgeist.

"Building 7" Explained

>> ^Fade:
Re. your point about funding. A 47 story skyscraper collapsing is a worrying event. Since the new york skyline is dominated by many such buildings, all at risk of fire you would think that funding for an investigation would be readily available.
The NIST report basically says that every building in New York is going to have to be rebuilt. That's hard to swallow since no building before or since has collapsed due to fire, therefore a rational conclusion would be that the investigation was potentially flawed and should be rerun.


Funding for an investigation was available; it's what NIST did. The government funding yet another investigation doesn't make much sense, especially since the NIST report was supposed to be a more thorough investigation after FEMA already made their preliminary investigation. And so far you haven't really given any good reasons to do so. There's no real evidence of controlled demos. And arguing via precedent (i.e. "other buildings didn't fall down!") is a fallacy and concluding their investigation was flawed on those grounds is illogical.

The alternative is a privately-funded investigation, but that means individuals have to cough up the cash. The NIST investigation cost about $16 million; I imagine just for WTC 7 probably ran a few million alone, so who is going to pay for it? Would you be willing to chip in a few thousand dollars of your own money to help fund such an investigation? How important is this to you really? Enough to cough up some real cash?

I'm really curious where this stylistic element of really tall skyscraper like ships originated in french animations. Riffing off triplets of belleview, or does it go deeper?

"Building 7" Explained

shponglefan says...

You're not making any sense.

First, the building falling into "into its own footprint at freefall speed" is indication of a) structual failure, and b) that gravity was working that day. In both cases, the building collapse wouldn't necessarily be any different. So this is not evidence in your favor.

Second, it's not my job to disprove your point. You're making the positive claim for a controlled demo; therefore it's your job to provide evidence for that claim. And so far, your evidence amounts to: a) the building fell down (which is irrelevant as it applies to both scenarios), and b) there were explosions (which based on my viewing of the videos sound nothing like controlled demo blasts, plus NIST also concluded there were no indications of blasts capable of destroying a structural column). So really, you don't have any real evidence of a controlled demo. At all. And claiming the lack of evidence is part of a cover-up is just a cop-out.

Incidently, I'm not making an argument from incredulity. An argument from incredulity (look it up) is "I can't imagine X, therefore X is impossible". I've never suggested a controlled demo is impossible. Rather that it's incredibly far-fetched given the complications of such an event and that you need some real evidence to support that claim in lieu of the more reasonable explanation. You haven't done that.

>> ^Fade:
A skyscraper falling into its own footprint at freefall speed. If you can provide evidence of this happening that wasn't the result of controlled demolotion then you might have a valid point. Until then you are arguing from incredulity which we have already established is a fallacy.
