The Fallout of a Helium-3 Crisis : Discovery News - 3 views

  • So short in fact, that last year when the looming crisis, which reporters had been covering for years, became official, the price of helium-3 went from $150 per liter to $5,000 per liter.
  • The science, medical and security uses for helium-3 are so diverse that the crisis banded together a hodge-podge of universities, hospitals and government departments to try and find workable alternatives and engineer ways to recycle the gas they do have.
  • Luís F. Simões on 22 Feb 11
     
    So, which shall it be? Are we going to increase the production of hydrogen bombs, or can we finally go back to the Moon (http://en.wikipedia.org/wiki/Helium-3#Extraterrestrial_supplies) ?
  • dejanpetkow on 23 Feb 11
     
    None of these. Either you recycle, or you take it from natural sources on Earth. Although most people don't know - there is plenty of natural He3 on Earth. It's just nonsens to use it for energy production (in fusion reactors) since the energy belance for getting the He3 from these source on Earth is just negative. Or you try to substitute He3.

    Recently, many competitions in the computer vision domain have been won by huge convolutional networks. In the image net competition, the convolutional network approach halves the error from ~30% to ~15%! Key changes that make this happen: weight-sharing to reduce the search space, and training with a massive GPU approach. (See also the work at IDSIA: http://www.idsia.ch/~juergen/vision.html) This should please Francisco :)

    to begin with european industry (and probably governments) would complain that ESA was taking business away from industry? or any part that started to make money would be quickly spun-off
  • LeopoldS on 09 Jun 10
     
    really bad interview in my view ... btw: how is CNES making money and how much?
  • Joris _ on 09 Jun 10
     
    CNES is known to be a semi-autonomous agency in the sense that it can auto-finance parts of its activities. Besides the money coming from the state, money comes from the participation of CNES in private companies (e.g. Arianespace) and its own activities (e.g. SPOT among others...). It is about 400M€ per year (almost a class-M mission in Cosmic Vision). For the figures (in French): http://www.cnes.fr/automne_modules_files/standard/public/p4354_c050f7963b54a839a843723401bfddf2budget.pdf

    "The Illinois Commerce Commission wanted to make sure that if they deregulated the power market, individual producers of electricity would not be able to manipulate the market during times of high demand by withholding capacity or charging excessive rates. The Argonne model found that during certain times of heavy load such a situation could emerge, which led to the recommendation that independent monitors maintain some oversight of the power market." Interesting this study on power grids !

    not overly impressive: "The Google data could not predict the weekly fluctuations in stock prices. However, the team found a strong correlation between Internet searches for a company's name and its trade volume, the total number of times the stock changed hands over a given week."

    the problem is that usually the google search queries and the twitter updates happen after a crisis for example. I dont really think that people all over the world suddenly realised that Lehman would collapse and started googling it like crazy before it collapsed. More likely they did it afterwards.

    wtf is this! As I read this morning in the newspaper (not even a scientific one), 1 TeV is the kinetic energy of a flying mosquito... so be careful ! It seems they already sloved every thing on this website: "At the Institute for Space Quantum Physics ISQP, it was already proved in 1991-1992 that dark matter is in magnetic fields as magnetic space quantum flux." This website is the biggest source of crackpots i have seen in a long time...! (http://www.supernovae-energy.com/)

    Come on guys, this website is hilarious! "The HAITI EARTHQUAKE (...) were impossible for the Institute for Space Quantum Physics (ISQP) to compute because on one single planet was on a common line or axis with the Sun: Venus."

    Unfortunately, most information I have about the guy (Hans Lehner, a Swiss) is in German, his official homepage is http://www.rqm.ch/ According to EsoWatch he is the Swiss analogue to Dr. Mills and his Blacklight power. Lehner apparently founded a company, which should have produced a "Raum-Quanten-Motor" that -- of course -- produces energy out of nothing. The theory is based on spookey forces mediated by Lehneronen. 11 Million Swiss Franks (about 8 Million Euro) were lost when the company bankrupt. And the guy is selling new stocks on his homepage again... Lehner calls another crackpot named Oliver Crane Zweistein (from Einstein being "Onestone") and himself "Dreistein". Now he is looking for Mister or Misses Vierstein. Perhaps you should apply, good luck!!

  • But not everyone is optimistic about discovering SUSY. "We will get in a crisis, I think, in a few years," Dorigo predicts, sceptical of the theory because it introduces so many new particles of which data presently show "no hints". However, even though he would lose a $1000 bet, he says that he would still be among the first celebrating if the LHC does turn up sparticles.

    Certainly too early for a definite answer, they will keep us in suspense for another few years. But don't worry, whatever is found, Arkani-Hamed will have at least 50 models that can explain this...

  • According to Facer, it was the crash of 1929 that led to the five-day week. "Before that it was common to work six-day weeks with 12 to 14-hour days. When the Great Depression hit, the idea was to share work around to get more people into employment." During the next big financial crisis in the 1970s, there was much talk of moving to a four-day week, but for a variety of reasons that didn't pan out. "Things are different now," says Facer. "I wouldn't be surprised if we could get 50 per cent or more of the workforce working four-day weeks in the next few years." Next up: the three-day week.

  • You needed models to create the intricate network of bonds based on the homeowners’ payments, models to predict prepayment rates, and models to predict defaults. You needed the Internet to sail these bonds back and forth across the world, massaging their content to fit an investor’s needs at a moment’s notice. Add to all this the complacency, greed, entitlement, and callous stupidity that characterized banks in post-2001 America, and you have a recipe for disaster.

    In the wake of the financial crisis, many started questioning different aspects of the economic formalism. Here a mathematical "dynamic" alternative to economic utility theory (which has also been the target of some famous recent attacks, see prospect theory) is developed and applied to the St. Petersburg coin tossing paradox. A good read at http://scitation.aip.org/content/aip/journal/chaos/26/2/10.1063/1.4940236
