An Extraordinary Time: The End of the Postwar Boom and the Rise of the Ordinary Economy, Author: Marc Levinson.
By Marc Levinson – Between 1948 and 1973, Australia, Japan, Sweden and Italy had not a single year of recession. West Germany and Canada did almost as well. The good times rolled on so long that people took them for granted.
Governments and the economists who advised them happily claimed the credit. Careful economic management, they said, had put an end to cyclical ups and downs. Governments possessed more information about citizens and business than ever before, and computers could crunch the data to help policymakers determine the best course of action. In a lecture at Harvard University in 1966, Walter Heller, formerly chief economic adviser to presidents John F Kennedy and Lyndon B Johnson, trumpeted the success of what he called the ‘new economics’. ‘Conceptual advances and quantitative research in economics,’ he declared, ‘are replacing emotion with reason.’
The Golden Age was wonderful while it lasted, but it cannot be repeated. If there were a surefire method for coaxing extraordinary performance from mature economies, it likely would have been discovered a long time ago. more> https://goo.gl/oQN8FL

By Leonid Bershidsky – In 2016, the Munich Security report noted almost in passing that the absence of the U.S. from discussions about the eastern Ukraine conflict would have been unthinkable before, and that the U.S. didn’t appear to be particularly interested in resolving the Syria crisis on its terms, either.
In 2017, all bets are off on what the U.S. will ultimately do: Donald Trump and members of his team have made so many conflicting statements on foreign policy (and some of them are quoted in the report, side by side) that nothing is clear except that they intend to keep their cards close to the chest as they “put America first.” more> https://goo.gl/he7BeX

Physics on the Fringe, Author: Margaret Wertheim.
African Fractals: Modern Computing and Indigenous Design, Author: Ron Eglash.
By Margaret Wertheim – The world is full of mundane, meek, unconscious things materially embodying fiendishly complex pieces of mathematics. How can we make sense of this? I’d like to propose that sea slugs and electrons, and many other modest natural systems, are engaged in what we might call the performance of mathematics.
Rather than thinking about maths, they are doing it.
In the fibers of their beings and the ongoing continuity of their growth and existence they enact mathematical relationships and become mathematicians-by-practice. By looking at nature this way, we are led into a consideration of mathematics itself not through the lens of its representational power but instead as a kind of transaction.
Rather than being a remote abstraction, mathematics can be conceived of as something more like music or dancing; an activity that takes place not so much in the writing down as in the playing out.
Since at least the time of Pythagoras and Plato, there’s been a great deal of discussion in Western philosophy about how we can understand the fact that many physical systems have mathematical representations: the segmented arrangements in sunflowers, pine cones and pineapples (Fibonacci numbers); the curve of nautilus shells, elephant tusks and rams horns (logarithmic spiral); music (harmonic ratios and Fourier transforms); atoms, stars and galaxies, which all now have powerful mathematical descriptors; even the cosmos as a whole, now represented by the equations of general relativity.
The physicist Eugene Wigner has termed this startling fact ‘the unreasonable effectiveness of mathematics’.
Why does the real world actualize maths at all? And so much of it?
Even arcane parts of mathematics, such as abstract algebras and obscure bits of topology often turn out to be manifest somewhere in nature. more> https://goo.gl/ifKV2Z

By Jacob Brogan – Corporate complicity: Many of us rely on Google, Apple, and their ilk to protect our accounts and information. Can we be sure that these companies have our best interests in mind when it comes to security and privacy?
Government involvement: As international, politicized hacking grows more common, governments may become more involved in private cybersecurity, potentially threatening individual privacy in the process. How much should we rely on political authorities as we work to reinforce our digital borders?
Human fallibility: Some security experts argue that humans are the “weakest link” in cybersecurity practices, but others counter that technology itself may be making things more difficult for them. Can we develop systems that won’t trip up reasonable, well-meaning people?
Inconvenience: Many of the most robust cybersecurity technologies also make it harder to use the internet. Can we guarantee our safety without sacrificing the things that make the internet fun to use? more> https://goo.gl/gLOn1s
