Well, its not weak. Sure there are MUCH stronger ones, but usually at the cost of size. There is even a 20T magnet 30 meter away from me right now, but the volume of the bore is only the size of a can of coke.
The energy density goes square with the flux, but linear with the volume, so the size makes the magnet quite special.
I read about it years ago, so my memory is abit hazy.
But they do have extensive field-quench protection systems. (they need it, as its by far the biggest liquid helium installation in the world).
One way they protect themselvs is that they are well below the critical temperature for the magnet at the current density they use. They also use liquid helium evaporation cooled to about 2K. And they have huge venting tanks for quench protection.
The sublimation heat of helium is not that big, but they have 10s of tons of it to carry away the heat.
You really dont need such datarates, even for the newest, best, ect ones. You simple dont get that much information out of electron detectors. If you want to push bandwith, you need high sample rates and get "real time" rubbish noisy shit. And for good statistics, 1-2 Mbit are more than enough. You arent playing Maxwells Daemon, you know, so there is no atom to catch or something....
At least that my opinion, as someone who was also dissapointed the first time he noticed that the 3 million $ SEM only outputs XGA Tiffs with 1024x786, 8bit greyscale, once every 5 seconds if you want nice statistics....
You can buy D2O, for example from sigmal aldrich, for moderate prices, compared to the rest of the equipment. I dunno the actual price, but i bougt 100ml high purity ND4OD, obviously harder to make, for 150$ for 50ml, so i guess 95% grade D2O schould be 50% for 100ml.
Its a non hazard material, non radiative, and WAY to common for any kind of sale restriction to make any sense.
Isotopic purification is dead easy if the weight ratio is 2:1, vs for example 235:239...
All the "you dont know jack" games, and the 2d worms games were absolutely perfect to even get absolute non-gamers playing. Sadly, the 3D Worms sucks... (the concept is just completely incompatible with a 3d playfield. I just wish the designers would get that idea, too, and make a sequel one can actually enjoy)
Oh, because if we build such a structure, nobody will ever need to get down again (hello x days latency until everything is cleared), and we will of course NOT shoulder the HUGE implication of just making a dual system with an up and down lane.
You are seriously mixing up tidal power with wave power generation. While the first really is moon-powered, the latter is, as a bastard child of the wind, solar energy at work.
You think that the output of roughtly several ten 1000 years of sun in a few hours is nothing much? I guess you would even consider a supernova not worthwhile...
"do you still believe in Internet privacy in the age of blogs, MySpace, LinkedIn, Meetup, and Flickr?"
Yes, i do. Thats the reason i dont have a blog, dont whore my photographs out to flicker, think myspace it a breeding experiment for retards and never heard of something called "meetup" before.
So i guess i dont really belong to the target demographics...
Here, in germany, (where this product is provided), metering of broadband isnt very common. You can get a DSL capped at 2Gbyte per month, if you want, but why if you can get it totally unlimited for 2 or 3 more per month?
But seeing that the policy of wikipedia FORBITS original reseach or works to be presented, i dont think that plagiatism isnt really that much of a violation here. Everybody with half a brain can suggest that the knowledge didnt manifest itself out of thin air, even without citations given.
You know, he build an universe, where technological progress just isnt infinite where humans live.
Also, your first statement is at best ambigous. Do you mean the present tense in the time of the book? Or nowaday technology? For the last one: You realize they good ramscoop spacedrives, live for 500 years and can do just about anything you expect from a not-quite far future SciFi enviroment.
And if you mean the first one: Actually try to understand the book. Technological progress is limited there by the inevitable collaple of civilisation after a few 1000 years, so progress "tops off". Traders like the queng ho can scavage the best whereever they stop, but just because they are so few, and traveltime is so long, its a slow thing.
Not to mention that you failed the whole concept of the galaxy of zones. To truly appreciate the context of the book, one should have read A Fire upon the Deep before (as without it, one doesnt really "get" the ending).
No, they wont. Sorry to break it to you, but image sensors arent cpus, so there is no moores law or anything. There is stuff like "physics" and "optics" that have to be taken into account.
To get that kind of resolution out of a single camera you would neeed lenses that are heavier than you (just to beat the diffraction limit), not to mention that the sensor would need to be HUGE (we are at 2-4 um^2 pixel sensor size today (and thats bad already for various reasons). It should be obvious why getting smaller 500nm or so isnt a good idea (hello wavelenght of light?!). Not to mention that the real bad "noise kills everything" would start quite a bit earlier. This big detector size would again demand better lenses... (think of large format, but with a need for precission like the best 35mm optics.
The only way to do it, in a handheld camera, would be if some breakthrough would enable negative reflraction index lenses (they can be _perfect_) and then using some ultra cooled detector. Even then the exposure times would be quite long just because of the quantum efficiency.
You dont actually need that much material for solar cells, if you produce them the right way. The whole concept of those thin film solar cells is that you can get nearly perfect absorption of the light in less than 5 um thickness. Add a base layer, a tin-oxide contact layer on top, and some surface protection, and its entirely possible to make a cell 0.1 mm thick, only 1/10 of it using potentially rare materials.
Who cares about the _edge_ of a thin disk, if you have the while top and bottom? Sure, the relative speeds are highest at the end, but >90% of the friction does NOT happen on the outer edge.

largest, in size, and strongest by the amount of energy contained (think about it: its has 100s of m^3 with nearly 4T flux)

Obviously your definition is rather narrow, or you are mathematically uneducated.

Everbody who defends those degrees here either has one, or is close to getting one.
Well, lets hope there is not too much wishfull thinking and denial behind it.

Spacecraft dont use x10 engineering safty margins.
They dont even use 50% margines.
If they did, they would never be able to lift of the ground.
Spare us from rants about your own incompetence.
Every computer build and sold the last years HAS to perfectly work with at least the S2 and S3 power-save modes. If not, its a defective product.
Not to mention that every AMD computer (thats a lot) can perfectly save at least 25% by enabling Q&C, which ZERO user impact.
Oh, because if we build such a structure, nobody will ever need to get down again (hello x days latency until everything is cleared), and we will of course NOT shoulder the HUGE implication of just making a dual system with an up and down lane.
Then make it 6mm.
Exponential intensity decay, anybody?

Depends on what you want.
With interferometry, you can get virtual baselenghts the size of the earth.
But when you want to get a weak signal, the 300m dish has an order of mangnitude more collection area than the closed 2nds.

Have you ever heard of self-policing real live communities?
They died out with the advent of the written law, in the middle ages.
What good does it do to "not be part of the community" for anybody when the net is just the medium for in effect quite conventional crimes?
Those documents were from pre1990, when bush was still provided with chemical weapons because he was "americas bastard" to controll the mullahs.
No, they wont.
