    "which raises the possibility - theoretically at least - that the machine could, with some modifications, build a copy of itself." - very interesting way to say that the machine can't build a copy of itself... But generally, this is ubercool :-) When you're getting one?

  • They both believe the systems engineering processes that have served the aerospace and defense community since pre-Apollo days are no longer adequate for the large and complex systems ­industry is now developing.
  • Joris _ on 02 Nov 10
     
    1) it has to actively work and produce a result that's what you intended 2) the design must be robust. 3) it should be efficient 4) it should minimize unintended consequences. "But we have to establish a formal, mathematically precise mechanism to measure complexity and adaptability . . . [where] adaptability means the system elements have sufficient margin, and can serve multiple purposes." "We need to break the paradigm of long cycles from design to product" some interesting questions....

    indeed ... already hotly debated in CDF ... any suggestions in addition to what we already contributed to this (e.g. system level optimisation)
  • Joris _ on 03 Nov 10
     
    what is the outcome of the CDF study ? I think actually that optimisation is not at all the key point. As it is stressed in this news, it is robustness (points 2 and 4). This is something we should think about ...

  • "The corporation promised to clean up the space in ten years by collecting about 600 defunct satellites on the same geosynchronous orbit and sinking them into the ocean subsequently,"
  • He said the cleaning satellite would work on nuclear power and be capable to work up to 15 years.
  • Energia said that the company would complete the cleaning satellite work-out and assembly by 2020 and test the device no later than in 2023.

    like also this one: "Some of the really savvy new media efforts like Flipboard are exciting, but after the initial "wow" factor wears off, these apps mainly serve to remind me that there's already too much good stuff to read out there, and that my life is slipping away from me in an infinite stream of interesting bits about smart animals, dumb criminals, outrageous celebs, shiny objects, funny memes, scientific discoveries, economic developments, etc.. I invariably end up closing the app in a fit of guilt, and picking up one of the truly fantastic dead tree or Kindle books that I'm working my way through at the moment, so that I can actually exercise my brain (as opposed to simply wearing it out)."

    Maxwell remains the great unsung hero of human progress, the physicists' physicist whose name means little to those without a scientific bent. His life's work [....] is among the most enduring scientific legacies of all time, on a par with those of his more widely acclaimed peers, Isaac Newton and Albert Einstein.

bio insect_wings flies

shared by pacome delva on 27 Apr 11 - No Cached
LeopoldS liked it
  • A new experiment reported in Physical Review Letters shows that—contrary to popular wisdom—paddling can be as effective in air as it is in water. This could imply that insects evolved their flight capability from some earlier swimming trait.
  • Using high-speed video cameras to track wing motion, the team observed certain cases where the flies paddled their wings forward and backward. To confirm that this was indeed drag-based motion, the team plugged their wing data into an “insect flight simulator” and found that they could reproduce the fly’s overall movement. The authors constructed a simple model of paddling, which seems to support the theory that insect wings evolved in water.

  • Luzi Bergamin on 18 Jun 11
     
    Hopefully I'm wrong, but I'm very pessimistic. I guess they will impose even more control, ask for even more detailed description of the results that will be delivered and concentrate even more on project funding instead of funding open research.
