ATV docks with the ISS | Bad Astronomy | Discover Magazine - 4 views

  •  
    On March 28, ATV-3, named Edoardo Amaldi, docked with the ISS. Astronauts on the station took this unbelievable picture of it as it approached

    More pics here: http://www.flickr.com/photos/europeanspaceagency/ ATV docking is a bit further down the photostream.

Past Future Predictions - 3 views

    "Computers in the future may weigh no more than 1.5 tons." Underoptimistic ... Excellent source of inspiration and quotation for all our reports
  •  
    put them on the wiki ....

    "Computers in the future may weigh no more than 1.5 tons." Technically, this is a correct prediction :P

Earth's atmosphere came from outer space, find scientists - 3 views

  • From that we now know that the volcanic gases could not have contributed in any significant way to the Earth's atmosphere
  •  
    tried to find the original science paper but could not .... the only one I found was this one: http://sciencenow.sciencemag.org/cgi/content/full/2009/1210/2

    "Plan 9 from outer space" quote confirmed : atmospheric conditions in outer space stall communications! Wonder how many more facts of the movie will prove right in the end...
  •  
    very interesting study. Although it is not so much a surprise, they cite many papers on planetary formation that predicted this, and the only paper on degassing they cite is from our rather unpopular french ex-minister of research c. allegre, who refuses the fact that humans have an impact on climate...

The quantum mechanics of time travel through post-selected teleportation - 3 views

  •  
    Giving the title, I think the comment is not necessary...
  •  
    Haha, nice article : One of the best-known versions of non-general relativistic quantum versions of time travel comes from Wheeler, as described by Feynman in his Nobel Prize lecture [16]: 'I received a telephone call one day at the graduate college at Princeton from Professor Wheeler, in which he said, "Feynman, I know why all electrons have the same charge and the same mass." "Why?" "Because, they are all the same electron!" And, then he explained on the telephone, "Suppose that the world lines which we were ordinarily considering before in time and space - instead of only going up in time were a tremendous knot, and then, when we cut through the knot, by the plane corresponding to a fixed time, we would see many, many world lines and that would represent many electrons, except for one thing. If in one section this is an ordinary electron world line, in the section in which it reversed itself and is coming back from the future we have the wrong sign to the proper time - to the proper four velocities - and that's equivalent to changing the sign of the charge, and, therefore, that part of a path would act like a positron."

Google's 8-Point Plan to Help Managers Improve - 7 views

  •  
    Well, well, Google says it. And all is a result of an algorithm..... Among the interesting fincings the algorithm says that technical competence of the boss is not needed..... against their own beliefs!!

    "Although people are always looking for the next new thing in leadership," he said, "Google's data suggest that not much has changed in terms of what makes for an effective leader."
  •  
    "Managers often want to hire people who seem just like them" does the ACT look like the managers or the managers like the ACT ? hmmm
  •  
    "the topic often feels a bit like golf" What other comparison can one use in an article aimed towards managers? :D
  •  
    nobody in the ACT plays golf yet as far as I know ...
  •  
    Which is a pity as you have a golf field not that far away :-D Maybe a good idea for a nice team building event??

    still practically as an ACT paper ... the first author was the first RF of the team and the one who suggested Dario ...

    Yeah I've figured it out from his CV at the end of the article after posting :)

    very nice selection of projects by NIAC!! there are at least some who have European partners as it looks like ... lets still see if we can get involved ...

    Interesting. Is it NASA's equivalent of ESA's GSP?
  •  
    It is a good thing NIAC is alive again. Wie, Bong -> "Optimal Dispersion of Near-Earth Objects" . I wonder what it is?
