Centripetal is the real force, centrifugal is the imaginary component.
Its not real damnit!

The description to this video is just FUD. He has never supported preemptive wars. He voted against the Iraq war and said the troops should have stayed in Afghanistan to finish off Bin Laden and the Taliban. Unlike Iraq, Most of Afghanistan WANTS more troops to help fight a resurgent Taliban (and thereby defend their basic freedoms from those fundamentalist nutjobs who would have women accused of adultery beheaded) Once we've fucked up a country with war we have an obligation to help rebuild it, if that's what you mean by "nation building".

"United Nations, NATO, and the World Bank"
Aside from the World Bank's usury, why show such contempt for international cooperation? One world government is not necessarily a bad thing.

"From the cave-spotted mountains of northwest Pakistan, to the centrifuges spinning beneath Iranian soil, we know that the American people cannot be protected by oceans or the sheer might of our military alone."
Iran actually DOES have centrifuges for enriching fuel for power plants, and such equipment could easily be reallocated to weapons production if Iran wanted to do so. Nothing about that statement is inaccurate, only your FUD interpretation of it is inaccurate. Obama has never supported attacking Iran. Apparently you think acknowledging the existence of a threat we might face is equivalent to advocating war. Irishman makes the same mistake. Obama is not warmongering, he is trying to build international cooperation. Counterterrorism does not require starting any new wars. He has said we will GTFO of Iraq by 2010 and just finish the job in Afghanistan.

"join overwhelming military force with sound judgment"
That's not saying we should start any new wars. The only war he's advocating is finishing the job in Afghanistan.

You won't find what I wrote on google because *gasp* I made it all up!

Do you want to know what keeps a motorcycle upright? Skywalker Force.

(But, seriously: It's centrifugal force.)

I seem to remember it being the centrifugal force of the wheels giving my bike the gyroscopic effect, but that was many, many years ago and that sounds pretty damn good, and I have yet to master the google magic, so thank you.


Dang, that google business isn't overrated. http://en.wikipedia.org/wiki/Bicycle_and_motorcycle_dynamics

I hate to be a know-it-all (I love being a know-it-all), but centrifugal force has nothing to do with it. It's the forces of the spinning wheels acting as a gyroscopic flywheel that enables the motorcycle to maintain an upright axis while the operator is left behind. As the velocity of the wheels decreases, the nutation (amount of travel in the side to side tilt) of the motorcycle increases and the bike loses stability.

The bike actually would right itself, how much track width needed for that speed I do not know, but centrifugal force of the wheels keeps the bike upright, you upset the balance by counter-steering and shifting weight. I know because I had first hand experience with a high-speed get off.

how on earth are those things keeping neutral buoyancy for so long??


I read the explanation posted in a previous comment, and it sounds like they make a rotating column of water (with their tails?), then shoot a bunch of bubbles into it - centrifugal force (from the rotating water) pushes the bubbles outward, and presumably some sort of friction where the rotating and non-rotating water meet keeps the bubbles from escaping. Even more impressive is that they're able to analyze the quality of the ring and then decide to blow another one to augment it, or if the ring is poor they'll let it go. These things are damned smart, it appears.

I don't think they sleep with half their brain at all times (as dgandhi referenced), rather that when they do sleep it's only 1/2 brain at a time. I'd love to be able to do that - shouldn't take more than 1/2 a brain to watch tv or mow the lawn or something.

Octane is heavier than air, but that's relatively insignificant compared to the random thermal movement of gas particles unless subjected to a very intense acceleration, like 100G in a centrifuge. Cruising at constant speed would allow it to spread out evenly.

This doc was so fascinating, I had to translate the interesting bits (which is about 90% of it):

Ants transnmit secret mesasges, and follow invisible paths. Their code is just now beginning to be cracked. Ants are not ordinary creatures. They can support 100 X their mass. Each ant individually has some extrordinary ability, so when they unite, they become a true superpower.

<Title: The Secret Organization of Ants>

We are in central Europe. These wood ants are in search of food. Their actions look random, each ant doing something different, but in reality, they are all working together, each doing its own specific job. In a single year, One colony can consume more than 10,000,000 insects.

Despite being so small, ants are one of the most formidable predators on the planet. They eat more meat than lions, tigres and bears combined.

When attacked by a predator, or subjected to a scientific experiment, wood ants all react in the same way. To defend their nest, the workers shoot formic acid. The life of a single ant is worth little. The sole goal is the survival of the colony.

A shot of acid in the nose or eyes is enough to make the bear turn away. The hive is now exposed, and about to face an enemy far more powerful than the bear. The bees don’t stand a chance.

The adults, having expended so much effort, seek out a much more energy-giving staple, honeydew – a sugar- and vitamin-rich stubstance secreted by aphids. In exchange for the production of honeydew, the aphids receive the ants’ protection. In a single year, a colony of wood ants may consume 100kg of honeydew.

In Indonesia, this relationship has been taken even a step further. These Indonesian ants still protect and drink from the aphids, but here they carry the aphids themselves from plant to plant, and even direct the aphids to the best, sweetest parts of the flower. They act as shepherds, tending to their flocks. These Indonesian ants are the only creatures on Earth to own domestic animals, besides humans.

When they detect a coming storm, they remove their livestock to the shelter of large leaves. After the storm, work resumes. The largest aphids, the mothers, receive preferencial treatment. They travel on the heads of the ants. The smallest make the jouney in the mandibles of their guardians.

Other speceis have developped far less pacificstic relationships. These are the carnivorous plants from the island of borneo. Some of their leaves form urns with ultra-splippery rims. Each pouch containds deadly liquid. This liquid digests insects that fall into the trap. All the insects climb up, attracted by the smell of its nectar. This giant carpenter ant isn’t the only ant about. This miniscule campanotus can walk the very dangerous rim without falling in. Once the giant falls in, it has no means for escape, and the tiny campanotus is put to the task. Unique among ants, it can swim underwater. It can also survive the liquid that is slowly digesting the carpenter ant. They eat their host’s victims, and in exchange, ensure their host’s protection from herbivores.

The tiny ants’ secret is demonstrated by their ability to walk the rim of the plant and get out of the water. Back in the laboratory, these ants are put in a centrifuge, and subjected to a spinning force 100X that of gravity, the ants still cling to the smooth surface. This secret lies in the miscroscopic film of liquid at the end of their legs. This skill is essential for building the nests.

Ant descended from wasps, and first appeard more than 100,000,000 years ago. Some species have retained primitive characteristics. These Australian ants still have the sting of their ancestors. Different from other species, the workers are nearly as big as the queen, and they lay their own eggs, though, non-fertile ones, which serve to nourish the larvae. Only the queen gives life to the next generation. Among other species, the organization of these ants is heirarchical. When a queen dies, several workers become fertile, and seek to replace her by eliminating their rivals. What follows is a ritualistic attack, where the ants attempt to wear out their opponents by striking them with their antennae, and pinching them with their beaks.

These conflicts are an exception among ants. Ants generally strive for the good of the colony. There are thousands of species of ants, and their prosperity rests not in the strength or abilities of the individuals, but in the organization of their society.

There is an immense diversity in this insect group, but all species of ants share a common trait: they all function as societies. No species of ant known lives apart from the others. The evolutionary transition from solitary to social has only affected 3-5% of animals, including humans, but this minority enjoys domination in almost all land habitats.

One of the most impressive examples can be seen in the pampas of Argentina. The ants are so organized in their gathering of food, that they represent a serious menace to the herds of something <cattle>?. Something else about the roof of their somethings. And I’m going to bed now.

Google came up with this patent for it:

"An array of parallel pipes, each having ports through which jet-like air streams exit, are arranged so that a peripherally directed air curtain is formed. The posts are shielded at both ends, and one end is provided with a chimney along a central axis of the air by which air or fluid is removed. By giving the air curtain a centrifugal force, a negative pressure is produced along a central core, and a spiral flow is produced, creating an artificial tornado."

I am also guessing they have an outlet for the fog in the ground and the lights up top added for making it more visible.

They have a small one at Universum Science Center in Bremen (site in german only, sorry) which is very cool because you can run your hand through it and interrupt the flow to see it forming from scratch again.

No centrifugal pumps there, its a large turbo, probably off a quite large diesel engine, and despite how angry it sounds, its not working that much harder than when it would be on an engine.. probably hotter, but not much harder..

biggest danger with that sort of thing is melting fuel lines etc.. fire.. fire is bad, except when its coming out of your own jet engine, then its gooOood.

As long as its not too late at night, they probably aren't breaking too many rules.. it does however look like a commercial garage anyway.

The two centrifugal pumps for turbines look kinda strange. Inlet at the back discharges to the outlet of the second stage? Then again, I guess it would have to, as the second stage wouldn't be very efficient if it was discharging into a volute of increasing size. (??)

that looks like such an incredibly bad idea...

one sharp turn and it's right onto its side... it's not like it leans, like a motorcycle, to compensate for centrifugal force. i don't know how they kept it stable in a couple of those shots...

edit: nevermind, just finished the video, and it's got 2000 lbs of lead on the bottom of the car, so umm, yeah... that'll do it.

you might want to impeach cheney first though

take action:
The one click form on this page will send your personal message to all your members of Congress, with your vote on the the question "Should Vice President Cheney be impeached?"
http://www.usalone.com/cheney_impeachment.php

Why?

Lying to congress and the American people:
* Lie #1 - Uranium from Niger - Bush said "The British Government has learned that Saddam Hussein recently sought significant quantities of uranium from Africa." in his State of the Union Address. The documents supporting that statement were forged.
* Lie #2 - Iraq and 9/11 - Bush led people to believe that Iraq was involved with 9/11 by repeatedly linking them in his speeches. This was so effective that at one point 70% of Americans actually believed Saddam was behind 9/11. Bush has since admitted that this was not true.
* Lie #3 - Congress Knew - Bush has stated that Congress had access to all the same information that the White House had. Thus he should not be blamed for making the mistake of going to war. But Bush was briefed many times about the falsehood of various stories and this information never reached Congress. [ZNet]
* Lie #4 - Aluminum Tubes - Bush, Cheney, Rice and Powell said that some aluminum tubes Iraq attempted to buy were intended for use in a uranium centrifuge to create nuclear weapons. These were the only physical evidence he had against Iraq. But it turns out this evidence had been rejected by the Department of Energy and other intelligence agencies long before Bush used them in his speeches. [NYTimes] [MotherJones] [CNN]
* Lie #5 - Iraq and Al Qaeda - Bush still insists that there was a "relationship" between Iraq and Al Qaeda. But the 9/11 Commission released a report saying, among other things, that there was no "collaborative relationship" between Al Qaeda and Iraq. The nature of the relationship seems to be that Al Qaeda asked for help and Iraq refused. Al Qaeda was opposed to Saddam Hussein because Saddam led a secular government instead of an Islamic government. [ZNet] [CNN] On 9/8/06 a Senate panel reported there was no relationship. [ABC]
* Lie #6 - Weapons of Mass Destruction - Bush insisted that Iraq possessed weapons of mass destruction but his "evidence" consisted mostly of forged documents, plagiarized student papers, and vague satellite photos. The United Nations was on the ground in Iraq and could find nothing. After extensive searches Bush was finally forced to admit that Iraq did not have weapons of mass destruction.
* Lie #7 - Mobile Weapons Labs - Bush and his team repeatedly claimed that Iraq possessed mobile weapons labs capable of producing anthrax. Colin Powell showed diagrams of them at his speech before the UN to justify invading Iraq. These claims originated from Curveball, a discredited Iraqi informer who fed Bush many of the stories related to WMD. On May 29, 2003, two small trailers matching the description were found in Iraq. A team of bio-weapons experts examined the trailers and concluded they were simply designed to produce hydrogen for weather balloons. But, for over a year, Bush claimed these were part of Iraq's bio-weapons program. The expert's report was suppressed and only recently made public. [WashPost] [ABC]
