Check your country impact on science!!! - 8 views

  •  
    Did you know that papers in space science are among the most quoted? Check how your country is doing .... you will be surprised :)

    In terms of country based quotations ("Most scited countries") I cannot access space science, only Geosciences, Immunology, Material Science, and Psychiatry & Psychology. But when I first saw the list of countries at the left under "Impact in Science" I saw Argentinia was on top, and USA was on last position. Yes, I was surprised, until I realised that is was just an alphabetical order. Did you see the same list?
  •  
    scotland's a separate country. must be preparing for independence already. and it's highest percentage is for space science. crazy
  •  
    Dajan, you need to click on the country you are interested in ....
  •  
    Nooo, can't be THAT simple.
  •  
    data a bit old .... newer data (but less well presented) at http://sciencewatch.com/ there you can also read: "The 20th century was largely dominated by the US as a major powerhouse of scientific research and innovation, with 40% of the papers indexed in the Web of Science fielded by US scientists in the 1990s. By 2009, that figure was down to 29%. The US now struggles to keep pace with increased output from Europe and Asia."

    Interestingly, Space Science is the only field in which my country has positive "Impact vs. world" value (even more interestingly as we don't even have a proper national space agency)...
  •  
    this might also be an indication / point to an issue with their data concerning space science publications ... quite surprising indeed that all Europeans are doing so well in this field
  •  
    Something should be wrong, for Spain I can read: Economics & Business 4.54 -28 Only minus 28!

MoNETA: A Mind Made from Memristors (IEEE Spectrum) - 0 views

  •  
    (don't forget to turn your hype-filters on...) MoNETA (http://cns.bu.edu/nl/moneta.html) stands for "MOdular Neural Exploring Traveling Agent". It is one of projects participating in the DARPA-funded SyNAPSE project ("Systems of Neuromorphic Adaptive Plastic Scalable Electronics"): http://www.darpa.mil/dso/thrusts/bio/biologically/synapse/index.htm http://www.darpa.mil/dso/solicitations/baa08-28.html

High efficiency solid state heat engine - 0 views

  •  
    We discussed this today during coffee. The inventor claims that he claims that a pressure differential can push hydrogen through a proton conductive membrane (thereby stripping off the electrons) which flow through an electric circuit and provide electric power. The type of membrane is fairly similar to that found in a hydrogen fuel cell. If the pressure differential is cause by selective heating this is in essence a heat engine that directly produces electricity. The inventor claims that this could be a high efficiency alternative to thermoelectric devices and could even outperform PV and Sterling engines with an efficiency close to that of fuel cells (e.g., ~60% @ dT=600K). I could not find any scientific publications as the inventor is not affiliated to any University - he has however an impressive number of patents from a very wide field (e.g., the "Super Soaker" squirt gun) and has worked on several NASA and US military projects. His current research seams to be funded by the latter as well. Here are some more links that I found: http://www.theatlantic.com/magazine/archive/2010/11/shooting-for-the-sun/308268/ http://www.johnsonems.com/?q=node/13 http://scholar.google.nl/scholar?q=%22lonnie+g+johnson%22+&btnG=&hl=nl&as_sdt=0%2C5

Have We Been Interpreting Quantum Mechanics Wrong This Whole Time? - 6 views

  •  
    "The experiments involve an oil droplet that bounces along the surface of a liquid. The droplet gently sloshes the liquid with every bounce. At the same time, ripples from past bounces affect its course. The droplet's interaction with its own ripples, which form what's known as a pilot wave, causes it to exhibit behaviors previously thought to be peculiar to elementary particles - including behaviors seen as evidence that these particles are spread through space like waves, without any specific location, until they are measured." Pilot-wave theory reresurrected. Maybe something for the next "fundamental" :P physics RF?

    And for the next 'Experimental Physics Stagiaire' position why not try to do "Unpredictable Tunneling of a Classical Wave-Particle Association" http://stilton.tnw.utwente.nl/people/eddi/Papers/PhysRevLett_TUNNEL.pdf, there are some rumors online that the results of Yves Couder Experiments can be reproduced with simple DIY vibrating tables! It is very funny to see the videos of the MIT's replication of this experiment (with lightening legends for those who are uncomfortable with the concepts involved https://www.youtube.com/watch?v=YF5iHQMjcsM)

Solar powered family car from the TU/e - 0 views

  •  
    TU/e is participating in the new Cruiser class of the World Solar Challenge. This competition entails building an eco friendly family car (instead of a racer) to prove that solar powered transportation is possible. Actually this car produces more solar power than it needs and has a range of 300+ km.

Scientists Accidentally Invent A Brilliant Blue That Will Never Fade * Materia - 1 views

  •  
    "But beyond its beautiful aesthetic, the pigment could help make buildings more efficient. This is because the pigment reflects a large amount of infrared light. As a result, a roof painted with YLnMn blue could help to keep buildings cool, thus conserving energy."

An extensive and autonomous deep space navigation system using radio pulsars :: TU Delf... - 4 views

  •  
    Interesting. these guys are apparently gonna try developing pulsar navigation. They propose to solve the low apparent brightness problem using relatively complex signal processing and filtering to limit the antenna size etc. The say they've already had some promising results using ground based data. worth a science coffee perhaps?
  •  
    Absolutely. Sante can you get in contact with them?

    interesting workshop on language here in Leiden ... Luis, Giusi??
  •  
    interesting indeed, but the lectures I'd be interested in already took place
  •  
    No good, 80% of these people are top quoted in my research area... I really should have been there. Evidently the organisers need to work on advertising.
