    And what does one win in the end? Yet another unfeasible concept to be archived somewhere in a journal? Look at "Millis hypothetical drives"... Give me a break, for sure!!

    I like the sentence "16 peer-reviewed journal articles, and an award-winning website (Warp-When), all for a total investment of less than $1.6M". This gives 100.000 dollars per peer-reviewed paper (we neglect the award-winning web-site under the assumption that is the easy part....). With these number the ACT in 2010 cashed 1.4 millions only in research papers making it an obvious good investment for the European Space Agency also in austerity times!!!

Space shuttle sci-fi Star Trek fun

shared by Luís F. Simões on 07 Mar 11 - No Cached
  • The Space Shuttle Discovery left the International Space Station this morning for the last time. To commemorate the ship's accomplishments over 27 years of service, the crew was greeted to a morning wake-up message from Capt. Kirk. "Space, the final frontier," Shatner said in a prerecorded message. "These have been the voyages of the space shuttle Discovery. Her 30-year mission: to seek out new science, to build new outposts, to bring nations together on the final frontier, to boldly go and do what no spacecraft has done before."

    here's a recording of the transmission: http://ia600406.us.archive.org/13/items/STS-133/03-07-11_STS-133_FD12_Crew_Wakeup.mp3 to quote from the thread at reddit: "When the space shuttle first flew, 55 americans were being held hostage in the embassy in Iran, and Ronald Reagan had just become president. That same year Prince Charles would marry Lady Diana, the HIV virus would be first identified, Post-It notes were invented, and a small company called Microsoft released it's new operating system MS-DOS."

  • This weekend, programmers from all over Europe will be gearing up to compete in the 5'th Catalysts Coding Coding Contest (CCC'11). This year, the theme is Astronautics.
  • The competition is also open to online participants.
  • Individuals or teams of up to three people will be given a series of challenging problems that must be solved as quickly as possible.
  • ...2 more annotations...
  • As a contestant, you must conceive of a proper solution and produce the correct output in order to advance to the next level. How you get there is completely up to you. You may use any computational means at your disposal.
  • Online contestants will not be eligible for prizes – they compete for glory alone.

shared by Luís F. Simões on 26 May 11 - No Cached
  • D-Wave develops computing systems that leverage the physics of quantum mechanics in order to address problems that are hard for traditional methods to solve in a cost-effective amount of time. Examples of such problems include software verification and validation, financial risk analysis, affinity mapping and sentiment analysis, object recognition in images, medical imaging classification, compressed sensing and bioinformatics.
  • Luís F. Simões on 26 May 11
     
    According to the company's wikipedia page, the computer costs $ 10 million. Can we then declare Quantum Computing has officially arrived?! quotes from elsewhere in the site: "first commercial quantum computing system on the market"; "our current superconducting 128-qubit processor chip is housed inside a cryogenics system within a 10 square meter shielded room" Link to the company's scientific publications. Interestingly, this company seems to have been running a BOINC project, AQUA@home, to "predict the performance of superconducting adiabatic quantum computers on a variety of hard problems arising in fields ranging from materials science to machine learning. AQUA@home uses Internet-connected computers to help design and analyze quantum computing algorithms, using Quantum Monte Carlo techniques". List of papers coming out of it.

    can we contribute in any way to this - or alternatively benefit from this research already now?

    Watch out!! I read quite a lot about the contribution by EPFL (apparently coordinator) and their boss, Henry Markram. From what I read, this is not really science, but mainly a PR campaign. The main motor in this project is attracting a lot of money and the main aim to do so is promising a lot of stuff that nobody will be able to deliver. Accordingly, Markram is a very controversial person in the business...
  • Luzi Bergamin on 20 May 11
     
    Oups, sorry! Of course I meant, "the main MEAN to do so...", but the aim justifies the means. Well, that's exactly Markram's motto, I guess.
  • LeopoldS on 21 May 11
     
    interesting info indeed ... I though still think that the overall goal of this project, even if too ambitious for the time being is interesting, no?
  • Luzi Bergamin on 22 May 11
     
    It's not about interesting or not, it's about serious science or not. Also the goal of a fortune-teller is interesting, isn't it? Any description of a good science project is too ambitious, that's normal and not necessarily PR. But personally I think there is a certain limit where a science project becomes a bad SciFi thriller. This one here is a dime novel, I think. But the too ambitious is not the only point I became very doubtful. I have seen quite a number of scientists and engineers from different fields; what I read about the character and attitude of this guy just hints towards the worst case scenario. It's presumptive evidence, I know...
  • LeopoldS on 22 May 11
     
    that bad! wow ....
  • Luzi Bergamin on 22 May 11
     
    You know me, I'm the bullshitter... You remember Kurzweil and his Singularity-nonsense. In a way this was very similar. Though I think Kurzweil and Markram are very different characters (The Singularity essentially is a religion, I can't see anything like that in Markram's claims) they seem to share an important point: they are both complete nerds that apparently never spent a single thought on the limits of science (in its English meaning) in general nor of their particular research field in specific. One may find this excusable, I don't. But even then, they make claims that the nerdest nerd must know that they are completely unrealistic and thus I just have to assume that they claim their nonsense on purpose. The reason in Markram's case clearly seems to be money. But all this does not mean that these nerds cannot produce valuable results.

  • The termination of NASA's space shuttle program marks the end of a nearly 54-year rivalry between the USSR and the United States to achieve superiority in space exploration.

LeopoldS liked it
  • a strategy to create self-healing, slippery liquid-infused porous surface(s) (SLIPS) with exceptional liquid- and ice-repellency, pressure stability and enhanced optical transparency. Our approach—inspired by Nepenthes pitcher plants13—is conceptually different from the lotus effect, because we use nano/microstructured substrates to lock in place the infused lubricating fluid. We define the requirements for which the lubricant forms a stable, defect-free and inert ‘slippery’ interface.
  • ts capability to repel various simple and complex liquids (water, hydrocarbons, crude oil and blood),

  • Policy makers would be much better placed to combat the effects of global warming if scientists had access to accurate measurements of the Earth's radiation balance from a dedicated satellite, claims an international group of physicists.
  • it estimates that the satellite could cut a decade or more from the time needed to make useful projections of global temperature at the end of the 21st century.

  • "Think of it as rapid prototyping in biology--we make the part, test it, and then expand on it," says Reshma Shetty, one of the company's cofounders. "You can spend more time thinking about the design, rather than doing the grunt work of making DNA." A very simple project, such as assembling two pieces of DNA, might cost $100, with prices increasing from there.
