Cool indeed.

Not directly related, but reminds me of something cool about vacuum: The air above us , the atmosphere, has weight such that it presses on everything from all directions (even "up") at 14.7 pounds per square inch. The effects of this aren't noticed, for example, when a dry piece of glass is placed on glass table. The air pressing down on the glass is equally counteracted by the air molecules under the glass pressing up. If, however, you wet the glass and press it onto the glass table, the counteracting air pressure from below is removed - the air pressure is now applied only to the top of the glass, so the full 14.7 pounds per square inch presses down and it's difficult to break the bond. Same reason suction cups work.

Poppet valve problem. Get a new brake booster.

That makes sense since space is a vacuum that they would test it in a vacuum. For some reason, I was thinking it was a land based telescope. I guess those are pretty much obsolete at this point.

Thanks!

It might help to start with what the Backplane Pathfinder actually is - it's a non-flight replica of the Webb telescope’s center backplane (that link has more info and pictures).

Chamber A allows simulating the cold environment the real telescope will face in space, and is the same vacuum chamber where Apollo spacecraft were tested.

Now, to answer your question: They are testing the test procedures for the real telescope! (source: NASA). I realise that doesn't exactly answer your question, but I haven't found details of the actual tests they plan to run... so as a distraction, here are some more images - http://jwst.nasa.gov/images_backplane.html

Vacuum cleaner with a long ass hose

Sadly, this is what passes as "HOW IT'S MADE" in the PR world. A bunch of people talking, a bunch of people playing it, a vacuum-form, and maybe one machine. These videos are so useless.

"I ONLY WANT TO USE THE FUCKING VACUUM."

Right around the 1:25 mark, you can see that there is a vacuum hooked into the unit. You can see it sucking up the smoke and particles.

a 1kw diode.......I work in telecoms around 300mW is the most ive seen, and thats extremly dangerous for your eyes.

This thing?

Uhh....nope....nope nope nope nope nope.

As to the fumes, it looks as though the front of this thing has a vacuum nozzle, you can see the dust particulate being sucked into it as he ablates the paint in some parts of the vid.

"Chinhyakkei" is a great show. Literally translated it means "Rare Scenes." Every week they invite people from around Japan to submit stories or scenery that is unusual or outright bizarre. A TV crew goes out to confirm and record it and then a panel of guest celebrities vote on which is the strangest submission. I think you get some prize money if the one you submit is voted most unusual. Some things I've seen on the show:
- A bicycle vending machine
- A parking lot where you pay the parking fee using one of those old-school vacuum tube conveyor systems
- The man with the longest mole whisker in Japan
- A house shaped like a soccer ball

Frankly I'm kind of surprised more clips from the show haven't ended up here in the wtf channel.

I need to buy a used one of these trucks to use as a gopher vacuum. I think that would finally do the job that nothing else has yet.

As you wrote " As has been mentioned above, you must simply have no idea what socialism is if you think America is even headed in that direction, we're headed the other way buddy" shows your lack of understanding of political systems.

You can 100% government control on 1 side and 0 government power at the other end

At the 100% you would have labels such as Communism
Socialism,Fascism and such. At 0 would be Anarchy


Our government is in the middle but sliding towards more and more government control and morphing into some for of Oligarchy by buying votes via socialist programs promised by the left.
Then the pudendum swing back and the republicans buy votes by promising to "undue" what the left has done.

Either way the people loose because nothing get totally undone. More and more government control ensues.



1 Yes I would like there to be ZERO dollars donations by corporations and people. Since the government owns public airways and grants them via FCC, hence ABC, CBS, NBC etc let these station allot public time for equal debate for ALL parties and persons. TAKE the money out of politics.

2 I do agree what you indicated by the Republicans and did this week was reprehensible. A passing a trillion + bill and and worse the extra "shit" to help banks and such. But to be fair to republicans , Democrats over screw corporations and republicans attempt to unscrew them.

3 school lunches - Government should not be in regulating school lunch- it should be a local thing. Republicans are just undoing Michelle Obama failed school lunch program. Just more finger pointing points for bloggers to use.

4 Federal government controls the laws in DC Its their little kingdom. They can re ban pot all day long.

Generally speaking there are 5 types of government:
Monarchy - rule by one - never truly exits
Oligarchy - ruled by few - most governments today
Democracy- rule by majority - Majority rule is a failed system.
Republic- rule by law - Law limits Government powers
Anarchy - every man for himself- Always short lived due to power vacuum.


You say " America is sliding away from socialism, and into corporatism" Well they are basically neighbors in the political spectrum which would be some form of Oligarchy. Neither necessary serve the people freely.


Both Democrats and Republicans are sliding headlong towards Oligarchy. One party is just trying to get there quicker than the other party.


Both parities have utterly failed its people. There is only 1 party that desires to steer this country back towards a Republic and that is the TEA party. They get stronger and stronger every time their party fail its constituents. Were not all right wing lynching nuts. That's just a myth promoted by left wing media to color you thinking to stay on the Democrat plantation.
Truth of the matter is that four in 10 Tea Party members are either Democrats or Independents. Go to a rally and see for you self.

Well, I disagree on a few points.
With no enforcement, enough people (it doesn't take that many) would spend the day robbing, raping, and causing mayhem that the rest of us would be relatively paralyzed, either by fear or by the requirement to constantly 'police' those bad actors.
Even with reasoned laws (which we no longer have) a relatively large force is required to enforce them, but much smaller and less dangerous a force than we have today.
As I recall, the country was split, but slightly a majority in favor of going to Iraq (or wherever they were told we should go) and a slight minority keeping quiet so they didn't seem 'anti American' or 'pro-terrorist'. Maybe that's wrong, but it's how I remember it.
The issue with anarchism is it means something different to nearly everyone. That means deciding what 'rules' are required for society to work will be near impossible, just setting up the system to decide goes against the plan.
I think with no government to stop them, we would see more wars of aggression (by warlords, it's happened in nearly every power vacuum), more abusive corporate power (although not welfare, true enough, but they'll get that money a different, worse way), and no voting to vote out the fed (although it would not exist in an anarchistic 'society' to be voted in or out). Currency would either go back to regional, or gold (not a bad idea).
Once again, I must say finance reform could go a long way towards having representation for the people.
Wait, in a true anarchistic system, no one votes, and there's no system to collect, count, and certainly not one to follow through with any 'votes', so how would individuals 'vote' anything 'in' or 'out'? It sounds like you really want representative government, not anarchy, you just want it to represent 'us' and not 'them' (them being special interests with deep pockets). If that's correct, I, and I think many others, are right there with you. We need to be organized to force reform, because the 'representatives' have no incentive to do it themselves.

Now I'm starting to think you just want to argue. If you're smart enough to make those technical assertions, you're smart enough to know that's not what the experiment was about, and that you're just adding data to confuse the lesson.
The experiment is about the effect of gravity on the moving objects under 2 conditions, and how their mass means nothing when determining THEIR accelerations/speeds in a vacuum. Period.
You want to introduce other, completely unobservable (and irrelevant to the lesson) forces and movements to say 'nope'. Technically, you may be correct in a way, but you must completely ignore the purpose and parameters of the experiment and assume inobservably small movements to make your point...a point that does not actually change the experimental findings or the lesson, but does confuse it thoroughly.

EDIT: I would note that, by your standards, exactly where the observer is positioned makes MORE difference than the different masses of the bowling ball and feather, as do the exact positions of the two...if dropped from exactly the same position, they hit at exactly the same time because their gravitational forces are in line.

I would also note that if you change it to say, unimpeded, they would cross any imaginary line in space at the same time (essentially what they mean), again your point becomes moot.
