  • #Turkey votes 51 to 48, reminds me of #Brexit. Like in the UK, the villages love it, the cities oppose it. The message: Countries don't matter much anymore. The big cities have transcended nationalism, rural regions react by celebrating nationalism. London is now closer to Istambul than it is to British villages.

  • Trump presidency as a graphic novel, from "Der Spiegel"
    Image form Post

  • So, whats just happened? Trump scored with the states and demographies that would have been classic Bernie voters. So, I guess lots of Bernie folks voted Trump. They were not proud of it, hence the opinion polling.

    The worst mistake now is to underestimate Trump. He won and partly against resistance from his own party. I think it is fair to say he can get things done. Not everything he will do will be bad, but some things could be very bad.

    I am particularly worried about climate change and the general state of the democracy. Trump can build on solid red in both houses and while they might try to stop him on other issues, they won't be much help with these two. Unless something very unexpected happens he will have a majority in the supreme court as well. This is perhaps most disconcerting.

    There is also opportunity: If he has the will, he might address some problems that no establishment candidate could ever fix: banks, guns, trade. Will he have the will? And can he be stopped from screwing up the climate/economy/democracy/world in a big way? Its now on the american people. Sorry guys, you brought it on yourself, get your cardboard signs ready, you will need them.

  • Save Happisburgh

    I'm writing this post and I don't even know where to begin but I can tell you that I am determined to not let this beautiful village be abandoned by the government.

    I live in Happisburgh on the Norfolk coast in the UK and the coastal erosion rate is high and it's incredibly sad to see the ongoing lack of investment due to the 'risk' we won't be here in maybe 40 years time.

    We have been promised time and time again that something will be done, only to be let down by those making the promises.

    Today, I am not asking for much. Today I am asking for your support to push this for debate in parliament and all I need is for support on this petition https://petition.parliament.uk/petitions/167171

    The central theme of complex systems research is to understand the emergent macroscopic properties of a system from the interplay of its microscopic constituents. The emergence of macroscopic properties is often intimately related to the structure of the microscopic interactions.

  • Just a few days ago we lost someone dear to us due to a tragic accident.

    In the wee hours +Frank Maxwell​ was winding down after yet another successful mission (as he did) when he was cruelly taken from his loving wife Alma and son Lucas.

    Our thoughts and prayers go out to them - we can only imagine what his family are going through.

    +Frank Maxwell was a collosus in the Irish Ingress game and was very well known, liked and respected internationally, by both sides.

    His phenomenonal enthusiasm and commitment will never be replaced.

    He was the very definition of a people person, reaching out beyond the game to the people behind the scanners.

    Complex networks arise in a wide range of biological and sociotechnical systems. Epidemic spreading is central to our understanding of dynamical processes in complex networks, and is of interest to physicists, mathematicians, epidemiologists, and computer and social scientists. This review presents the main results and paradigmatic models in infectious disease modeling and generalized social contagion processes.
