judging from your silence on the subjects of the original arguments you were making it pretty much looks like you've lost them all thoroughly and are now simply trying to change the subject. you lose. bye.
jeez dude, you should really search, uhmmm this thing called the interwebs before letting yourself get raped by the ABSURDLY high prices these journals demand for a single paper! look. here. FREE! If you're an American YOU ALREADY PAID FOR THIS research. that's why it's on a NASA site for free. even when it isn't taxpayer funded research it's still VERY common to see a paper from a peer reviewed journal also up on a professor's personal page as a preprint or whatever.
ugh I can't believe I'm still talking to you. do you know how to use a calculator einstein? wrt dimethyl Hg I stated that "1 or 2 milligrams of which will ensure your death". you obviously pulled the 0.001 ml figure off the wikipedia page. 0.001 ml of water is 1 milligram of water, duh, dimethyl Hg is 3x the density of water, hence the lethal dose is a few milligrams. none of the wording in your original post specified the intent that you are now claiming and if you DID know what you were talking about, which I still doubt, your wording was grossly imprecise, so I'm not even going to address your claim that I was "misdirecting". YOU'RE the one misleading with all the "oh NOESSS HgO is so TOXICCC!". Yeah it's toxic, if you fucking EAT IT. It's RELATIVELY INERT compared to all organoHg compounds. SO IS CINNABAR, the NATURALLY OCURRING HgS mineral! You also seem to be under the laughable impression that "Why do you think that its specifically fish contaminating us? That's the only reason we're have rising human [Hg] concentrations.". Sorry, mercury in marine fish does not come from coal fired power plants, or for that matter almost any other human activity (except in special cases like Minimata). Freshwater contamination by Hg is solely a result of improperly dumped industrial liquid waste. CFL manufacture AND DISPOSAL has NO impact there at all.
"It really doesn't matter what type of mercury is in those bulbs."
thanks for the science lesson sprinkled with yet more bullshit. really? it doesn't matter? great, I'm going to personally ensure that all of the cfl bulbs you buy are now filled with dimethylmercury. exposure to more than 1 or 2 milligrams of which will ensure your death. mmk? your claim that "All forms of it that get into the environment do eventually turn into the very type that hurts us most." is equally stupid. most metallic mercury "entering the environment" (where do you think it came from? mars?) is not converted to organometallic form. it's oxidized to HgO which is insoluble and largely inert.
BULL-fucking-SHIT. The ~3 MILLIgrams of Hg in a CFL are in an entirely inorganic metal amalgam form. Stop pulling wacky pseudoscience scare tactic shit out of your ass and claiming it as truth.
so let me get this straight, you actually think that "defense" of Social Text by the editor is somehow convincing, and not merely the ultra-pretentious whinings of a petulant bedwetter who's obviously been foisted by his own? how embarrassing for you.
Presumably then this new meV He microscope will use neutral atoms? If so, I don't understand how they could image a surface at very high resolution. I know the corresponding DeBroglie wavelength of a beam of He must be very small indeed, but the actual physical size of the He atoms surely must be larger than the current sub-angstrom limit of monochromatic spherical-abberation corrected e microscopes no? So then what am I missing? What's the benefit here. You seem clueful, can you or the parent tell us more about this new low energy He beam stuff?
Thank you for writing my what the fuck comment for me! I've never seen a moderately interesting story turn into a flaming pile of shit quite as quickly as this one. The comments by this Wolfgang Forstmeier person constitute perhaps one of the stupidest statements I have ever heard coming from a scientist (or for that matter anyone). ever. Either he was somehow taken grossly out of context, the translation from German was shitty, or he is an imbecile utterly unworthy of the title scientist. No one who knows anything about how science or rational inquiry as a whole actually function, would ever seriously dribble out such a moronic proclamation.
Excuse me, why is the above twaddle modded up to a +3? This person obviously has not spent the better half of a single second actually looking for the images they decry as being "unreleased". Because if they had, they would've found even the most casual perusal of the websites for any of the recent space probe missions turns up TENS OF THOUSANDS OF RAWIMAGES for each one. Your incompetence in locating EASILY accessible information from NASA websites isn't their fault.
Because the problem of failing RTGs is not due to radioactive decay. RTGs use Pu-238 which has a half life of 88 years. It's just as hot as when it launched. The problem is dopant migration in the semiconductor heterojunctiontions (peltier junctions) of the part that creates the electricity. They degrade over time and put out less electricity for the same reason an LED fails gradually over time slowly emitting less and less light for the same amount of energy put in.
omigosh you're right! I forgot to consider that pink unicorns could be swooping in to guide the deuterons together at the last nanosecond! I'm sorry, if your theory requires the entirety of the standard model of particle physics to be swept aside in order to be explained its probably 99.9999999% likely to be BULLSHIT.
I am unaware of a single website which has such a list though this used to maintain such a list, it hasn't been updated in ~8 years and is GROSSLY outdated and inaccurate now. Certain International Atomic Energy Agency papers in their journal of fusion research have moderately complete lists. Also, I have put together a list of most of the biggest / highest energy fusion related lasers (both historic and current) in wikipedia's pages though even that's getting a bit outdated now.
The top 5 highest energy lasers though are: NIF (the National Ignition Facility at Livermore Labs at ~100KJ/pulse now and planned to be 2 MEGAJOULES within a year or so when it's completed), OMEGA (at the lab for laser energetics at 30 KJ/pulse in the UV spectrum), NOVA (at LLNL in the 80's and 90's, now defunct but used to produce ~30-40 KJ shots), GEKKO XII (in Japan at 5-10KJ / pulse), and then OMEGA EP (in long pulse mode at up to 5 KJ/ shot).
As to the top 5 most powerful I really don't know. We're the most powerful right now with OMEGA EP, next powerful might be either the Vulcan petawatt at RAL un the UK or Japan's 500J petawatt. Both lasers incidentally use parts from the dismantled NOVA laser from LLNL.
it's not possible to aim it at a person. the beam is vastly too intense to propagate through air. you would simply break the air down into a plasma spark where the beam exits its vacuum tube. you would have to put the [person INSIDE a vacuum chamber in order to ever actually hit them with the thing, but you'd be dead anyway inside there!
It is NOT a coincidence and that's why I submitted it mid-day YESTERDAY with mention of this very fact. After which time/. decided to sit on the story for a day, strip out half the useful information and links I originally included, and THEN publish it.
Interesting, you're right on par with the Uof Michigan's 20J / 30fs pulse laser then. But honestly what can you do with 10-20J? it's so little energy. What sorts of things are you guys doing with these ultrashort pulse lasers? The Japanese GEKKO XII laser people pretty much determined that you don't need pulses shorter than 1-10ps for fast ignition fusion studies so you must be doing other stuff with it...... laser wakefield acceleration....?
I'm sorry the article didn't contain all the information I included when I submitted it../ edited the shit out of it.
the instantaneous power for a single pulse is in the range of 1 petawatt (million billion watts)
the energy per pulse is a maximum of ~1 kilojoule for a petawatt pulse (1 picosecond) and 2-3kj for nanosecond pulses - we're limited by laser power damage thresholds for optics like 4 foot wide diffraction gratings etc.
the laser cannot operate in CW mode
the average energy is LOOOWWWWW, we can only do one pulse per hour because the neodymium laser glass heats up so much during a shot and produces wavefront aberrations in the beam.
I would be glad to answer any other questions you may have....
you're right,it certainly could've been worded more accurately, but in my defense,/. edited the HELL out of what I submitted - removing links everywhere and CUTTING OUT A LOT of more interesting information like gee, I don't know what the laser will mainly be be used for. Which is really annoying because the hawking radiation stuff is only a minor part of what we're doing. They sat on the submission for a whole day and to answer the question of the poster below, NO it wasn't an accident that this was submitted on the 48th anniversary of the first laser being created and I mentioned that in my post. Very disappointing the editors here seem to think their readers can't handle a little hard science anymore. I think I'll go elsewhere when I want to submit a story from now on.....
one can't help but wonder how long you've considered it a worthwhile endeavour to ferret out nonexistent logical fallacies in imagined misconstruals of your nonsensical ramblings. hand indeed dr. crazypants.
Slashdot Mirror
as opposed to what? pole dancer style?
the failure after startup was due to poorly welded superconducting busbars. its unrelated to what you are talking about.
congratulations, you're not only utterly scientifically illiterate and clueless but also an enormous douchebag.

wrong. The Corrective Optics Space Telescope Axial Replacement (COSTAR) package contained only mirrors not lenses that corrected Hubble's vision.
