He got into an ultra-light aircraft to guide birds during their migration - from the video it seems that only very few birds think he is credible (as a guide). --> http://www.telegraph.co.uk/news/worldnews/vladimir-putin/9524900/Flying-Vladimir-Putin-leads-birds-on-first-ever-migration-in-latest-publicity-stunt.html

  •  
    "A platform for public participation in and discussion of the human perspective on machine-made moral decisions" Machine Ethics is basically the return of philosophy through code. Here you can learn a bit about it, and help the MIT collect data on how humans make choices when faced with ethical dilemmas, and how we perceive AIs making such choices.

    "The One Hundred Year Study on Artificial Intelligence, launched in the fall of 2014, is a long-term investigation of the field of Artificial Intelligence (AI) and its influences on people, their communities, and society." (...) "The report is designed to address four intended audiences. For the general public, it aims to provide an accessible, scientifically and technologically accurate portrayal of the current state of AI and its potential. For industry, the report describes relevant technologies and legal and ethical challenges, and may help guide resource allocation. The report is also directed to local, national, and international governments to help them better plan for AI in governance. Finally, the report can help AI researchers, as well as their institutions and funders, to set priorities and consider the ethical and legal issues raised by AI research and its applications."

Our approach to replication in computational science - 2 views

  • So what did we do to make this paper extra super replicable? If you go to the paper Web site, you'll find:
  • p.s. I think I have to refer to this cancer results not reproducible paper somewhere. Done.

    good discussion on the replicability/reproducibility of scientific results (also a nice example of how to do it right... in bioinformatics at least)

Erdős-Bacon number - Wikipedia, the free encyclopedia - 2 views

  •  
    ever heard of the Erdős-Bacon number? :-)
  • ...1 more comment...
  •  
    There is a tool (http://www.ams.org/mathscinet/collaborationDistance.html) which computes your Erdös number. But who cares about Kevin Bacon?
  •  
    and actors probably ask who cares about Erdős :) The network of actors who co-star in movies is a famous one among networks people. Kevin Bacon became famous in that network because of fans of his who could from memory trace the paths of a large number of actors back to him :) see: http://en.wikipedia.org/wiki/Six_Degrees_of_Kevin_Bacon#History If you have you publications in http://academic.research.microsoft.com/, it gives you a nice tool to visualize your graph up to Erdős. Apparently I have a path of length 4, and several of length 5: http://academic.research.microsoft.com/VisualExplorer#36695545&1112639

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 :)
  • ...7 more comments...
  •  
    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!

Did dark matter kill the dinosaurs? : Nature News & Comment - 1 views

  •  
    theoretical physicists... :) Read the last sentence of the paper...in this way anyone can publish in nature...just make a good story with little evidence Did dark matter kill the dinosaurs? The Solar System's periodic passage through a 'dark disk' on the galactic plane could trigger comet bombardments that would cause mass extinctions.
  •  
    Hmm.. right.. then again, this is not an actual journal publication but a news broadcast. But you are right that the name Nature is attached to it so the journal is definitely banking on their acquired status.

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

Extreme weather events study - 2 views

  •  
    Is this correct? The conclusions indicate that contrary to what felt extreme weather events are not increasing?? Where is the trick?
  •  
    don't get fooled, this is the same strategy employed successfully by the tabac industry: installing doubt - all under the cover of science of course and using its methods; remember all these publications showing the overall beneficial effects of smoking, the "un-clear" link to lung cancer etc ... same here

Harvesting the plastic scattered in the ocean - 2 views

  •  
    Plastic needs a timescale of millenia to dissolve in the ocean and in the meantime it is accumulated in the water due to systematic dumping of garbage in the ocean since decades. Deploying buoyant devices at the location of the gyres (permanent circular currents in the ocean) is proposed for collecting the thin particles. The ambitious concept was developped by a Delft student, presented at a TEDx (see link), made a feasibility study through crowdfunding and now announces a public contest for developing mechanical parts of the harvesting system.

NASA set to debut online software catalog April 10 - 1 views

  •  
    The catalog, a master list organized into 15 categories, is intended for industry, academia, other government agencies, and general public. The catalog covers technology topics ranging from project management systems, design tools, data handling, image processing, solutions for life support functions, aeronautics, structural analysis, and robotic and autonomous systems. NASA said the codes represent NASA's best solutions to an array of complex mission requirements. McMillan reported that "Within a few weeks of publishing the list, NASA says, it will also offer a searchable database of projects, and then, by next year, it will host the actual software code in its own online repository, a kind of GitHub for astronauts."

ISEE-3 Reboot Project - Recovering an satellite from deep space by crowdsourcing @SpaceCollege - 3 views

  •  
    "A band of space hackers and engineers are trying to do something never done before - recover a 36 year old NASA spacecraft from the grips of deep space and time. With old NASA documents and Rockethub crowdfunding, a team led by Dennis Wingo and Keith Cowing is attempting to steer ISEE-3, later rechristened ICE, the International Cometary Explorer, back into an Earth orbit and return it to scientific operations. Dennis says, 'ISEE-3 can become a great teaching tool for future engineers and scientists helping with design and travel to Mars'. Only 40 days remain before the spacecraft will be out of range for recovery. A radio telescope is available, propulsion designs are in hand and the team is hoping for public support to provide the small amount needed to accomplish a very unique milestone in space exploration
