    not overly impressive: "The Google data could not predict the weekly fluctuations in stock prices. However, the team found a strong correlation between Internet searches for a company's name and its trade volume, the total number of times the stock changed hands over a given week."

    the problem is that usually the google search queries and the twitter updates happen after a crisis for example. I dont really think that people all over the world suddenly realised that Lehman would collapse and started googling it like crazy before it collapsed. More likely they did it afterwards.

    Water is used for keeping the graphene stacks separate. Without water or some other separation method the different graphene stacks would just stick together and graphene would lose its nice properties (like a huge surface). So, water has nothing to do with energy but is just the material which keeps the graphene stacks at distance. The result is a gel. Still, energy needs to be stored in the gel.
  • LeopoldS on 09 Nov 11
     
    and the different graphene layers act as anodes and cathodes??
  • dejanpetkow on 09 Nov 11
     
    Layer orientation in a gel is random. Additionally to that, cathodes and anodes are about charge seperation. Graphene layers are (as far as I understand) supposed to provide huge surfaces to which something, maybe a charge, can be attached. So do we need ions and electrons? Probably not. Probably just electrons which can travel easily through the gel. I guess the whole gel (and all layers inside) would be nagtively charged, making the gel blob a fluid cathode. But again, it's just a guess.
  • LeopoldS on 10 Nov 11
     
    Wouldn't it be worth having a closer look?

    The only extraterrestrial life detection experiments ever conducted were the three which were components of the 1976 Viking Mission to Mars. Of these, only the Labeled Release experiment obtained a clearly positive response. [...] These analyses support the interpretation that the Viking LR experiment did detect extant microbial life on Mars.

The Emerging Revolution in Game Theory - Technology Review - 2 views

shared by Luís F. Simões on 21 Aug 12 - No Cached
  • The world of game theory is currently on fire. In May, Freeman Dyson at Princeton University and William Press at the University of Texas announced that they had discovered a previously unknown strategy for the game of prisoner's dilemma which guarantees one player a better outcome than the other. That's a monumental surprise. Theorists have studied Prisoner's Dilemma for decades, using it as a model for the emergence of co-operation in nature. This work has had a profound impact on disciplines such as economics, evolutionary biology and, of course, game theory itself. The new result will have impact in all these areas and more.

    for the drag effect, this is well known in fluid mechanics, we use the Knudsen number, which explains this phenomenon ... for a perfect gaz though!
