    The redbull mission will attempt to transcend human limits. Supported by a team of experts Felix Baumgartner plans to ascend to 120,000 feet in a stratospheric balloon and make a freefall jump rushing toward earth at supersonic speeds before parachuting to the ground.

    since months austria is not speaking about anything else ... hope it is over soon :-) seriously: they even had last year Armstrong coming over to discuss with this guy on television (have posted it here) and the whole Red Bull advertisement machinery is working full speed on this ... quite impressive for just a jump ...

    The human brain both stores and processes information at the same time. Now computer scientists say they can do the same thing The human brain is an extraordinary computing machine. Nobody understands exactly how it works its magic but part of the trick is the ability to store and process information at the same time.

    The mantles of Earth and other rocky planets are rich in magnesium and oxygen. Due to its simplicity, the mineral magnesium oxide is a good model for studying the nature of planetary interiors. New work studied how magnesium oxide behaves under the extreme conditions deep within planets and found evidence that alters our understanding of planetary evolution.

    just another attempt to revive cold fusion from the dead ... and all with dubious experimental setups; read the last phrase ""From my perspective, this is still a physics experiment," Zawodny said. "I'm interested in understanding whether the phenomenon is real, what it's all about. Then the next step is to develop the rules for engineering. Once you have that, I'm going to let the engineers have all the fun." He went on to say that, " All we really need is that one bit of irrefutable, reproducible proof that we have a system that works. As soon as you have that, everybody is going to throw their assets at it. And then I want to buy one of these things and put it in my house."

    Creating jobs in the 21st century. Banks and insurance companies are firing mathematicians because they follow logic's rules when calculating product costs and rates. However, this work is being shifted since years to the marketing departments. Didn't you know that marketing experts are able to perform complex calculations as well, even improving the equations by adding market developments? Anyway, thousands of mathematicians need a job now, why not in the patent offices?

And the interviewed guy in the article say that this would benefit mathematicians !!! what a joke ! And all the schools that will have to pay billions to Euclid's heirs ! This would kill physics too, and all domains that use mathematics as a tool !

    I think it is worth noting that Dyson's is not saying that climate change is an illusion - it is evident that a lot of CO2 is emitted into the atmosphere and hence something will change. His point is that we just don't know what will change and by how much and that (much) more experimental data is necessary to make predictive models.

    Actually Sante and me just reviewed their paper. Although (some of) the scientists in the paper seem to have good track records their experimental techniques are by far not the best to determine the excess amount of energy produced. Even though their methods may introduce fairly large errors they would not be able to negate the cited power output - so they either are super-sloppy (i.e. they lie) or there is TRULY new physics involved... A big problem is that they are basically verifying somebody else's experiment - however because this guy is paranoid he does not tell them exactly what he did. In fact they went to his lab and used a setup that HE put together. All they do is do a measurement on it and it seems like they try to be thorough. There is quite a chance that the guy behind it all (Rossi) is setting them up - personally I would think >95%. However, the implications of this being new physics are so big that I think further research should be conducted.
  • LeopoldS on 24 May 13
     
    I just answered something very similar to Franco, except the conclusions: I don't think that there is a good reason for us or anybody else in ESA to get involved at this stage.
  • johannessimon81 on 24 May 13
     
    I agree - if this device would work it there would be other interest groups (like the energy sector) with a much more concrete stake in the technology.

    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 :)

    Hopefully the money wasted on the brain project will be offset by the gains on graphene... When I heard the proposals presentations on fet11 conference back in 2011, the graphene project was my bet.. Although its motivations were mostly political ("everyone else is working on graphene so if Europe won't do something, we'll soon be far behind"), in contrast to other projects it appeared to have well defined tangible objectives and gave hope of actually delivering something.

    Interesting approach, but with 99.9% probability they will miserably fail (at least in terms of their time schedule) simply because the technology is untested. I haven't read the refs (which miss by the way important works of E. Ahedo et al. on magnetic nozzle acceleration by ambipolar effects), but 1. using water means that you produce oxygen radicals which will erode chamber walls (ionisation efficiency is not 100% and experimental tests haven't been performed yet). 2. Electronic excitation (and radiation), rotational excitation, vibrational excitation, and dissociation are all processes which consume energy and reduce ionisation efficiency drastically. 3. It is a miniaturised Helicon thruster. Theoretical analysis probably does not consider near field effects. Far field models are probably not applicable due to the size of the thruster. I expect some surprises during thruster testing. In any case - good luck!
  • dejanpetkow on 05 Jul 13
     
    Apparently, there is only one qualification constraint regarding CubeSat propulsion which is related to volatile propellant. Since they use water as propellant and are also the owner of the CubeSat it is actually up to them how they qualify their thruster. Given that it is also possible to qualify the thruster within 18 months - since they define what "qualification" means.
