The man behind the sphere, Freeman Dyson, is dead at 96:

Freeman Dyson, a physicist whose interests often took him to the edge of science fiction, has died at the age of 96. Dyson is probably best known for his idea of eponymous spheres that would allow civilizations to capture all the energy radiating off a star. But his contributions ranged from fundamental physics to the practicalities of using nuclear weapons for war and peace. And he remained intellectually active into his 90s, although he wandered into the wrong side of science when it came to climate change.

Degrees? Who needs 'em?

It's difficult to find anything that summarizes a career so broad, but a sense of his intellectual energy comes from his educational history. Dyson was a graduate student in physics when he managed to unify two competing ideas about quantum electrodynamics, placing an entire field on a solid theoretical foundation. Rather than writing that up as his thesis, he simply moved on to other interests. He didn't get a doctorate until the honorary ones started arriving later in his career. His contributions were considered so important that he kept getting faculty jobs regardless.

    Economics is too dependent on human behavior, which is always changing. It's basically group psychology for how people relate to money and work. That's why the economics Nobel Prize is not a real one, and sponsored by some bank.

    Economics is too dependent on human behavior, which is always changing.

    Sorry, you're not even wrong. First, it can be applied to completely non-human systems like carrion feeding or pollination, or to systems that are technically human, but have no human actors directly in the system like high frequency trading.

    Second, even when we apply it to human systems with human behavior, it's not about the behavior, it's about the function of economic systems (like their ability to distribute resources), and the dynamics of the system (like what behaviors are rewarded or the system's propensity for breaking down) - both which are objective features of the system and hence, something that can be targeted by scientific study. Human behavior is just the present preferences and quirks of the actors in the system. It doesn't matter to the economics of the system what the behavior happens to be. Even when those behaviors lead to large scale dysfunctions like market crashes, the dynanmics are still part of the standard economics of the system.

    It's basically group psychology for how people relate to money and work.

    Except when it's not, of course.

    That's why the economics Nobel Prize is not a real one, and sponsored by some bank.

    Just like the Nobel Prizes for Literature and Peace?

      What fundamental results has economics given us? That Nobel Prize is closer to the peace and literature ones than the scientific Prizes. That it exists at all is an attempt to give academic gravitas to the subject. The marketing does not impress serious people.

        What fundamental results has economics given us?

        Supply and demand, markets, TANSTAAFL, betting and speculation infrastructure, and macroeconomic measures of a society's economy come to mind.

          "supply and demand" is just counting. Trivialities are insights now? The rest is mumbo-jumbo. Markets have existed for thousands of years. There is little innovation.

          Compare the enormous technological progress produced by real science to the never-ending political bickering produced by the "soft sciences" like economics.

            One can say the same about any science and be just as wrong. Supply and demand is an important observation about the dynamics of trade.

            Markets have existed for thousands of years. There is little innovation.

            Only if you aren't paying attention. High frequency trading, for a glaring counterexample, is far from those ancient markets.

            Compare the enormous technological progress produced by real science to the never-ending political bickering produced by the "soft sciences" like economics.

            Political bickering like the greatest improvement in the human condition ever?

              Supply and demand is trivial compared to Maxwell's equations or DNA or the periodic table.

              High frequency trading is the same thing as normal trading but faster and with computers. It's like during the dot-com boom when things were called great because they used the internet.

              Those improvements you see are not because some economist had a good idea. They are organic developments.

                Supply and demand is trivial compared to Maxwell's equations or DNA or the periodic table.

                Those phenomena you just mentioned are trivial in comparison to human behavior. Does that make them not science now?

                High frequency trading is the same thing as normal trading but faster and with computers.

                Just like nuclear war is the same thing as normal war, but faster? One enormous difference is the "with computers". Where's the human behavior excuse now for de-scientizing economics? Another is that it's so fast now that relativistic effects like light speed constraints come into place. If they speed the trading up much more (say about two to three more order of magnitude than current state of the art), then the market will have to be physically located on a single chip.

                Those improvements you see are not because some economist had a good idea. They are organic developments.

                Except, of course, when they are. The Black-Scholes-Merton model [wikipedia.org] (which incidentally is comparable in complexity with the Maxwell equations or the Periodic Table) and the variety of pricing/valuation techniques for derivative securities are all due to three economists having a good idea.

        More on this:

        That Nobel Prize is closer to the peace and literature ones than the scientific Prizes.

        Of course, that's false. Look [nobelprize.org] at what the prizes are awarded for:

        • Physics: “for theoretical discoveries in physical cosmology”, “for the discovery of an exoplanet orbiting a solar-type star”
        • Chemistry: “for the development of lithium-ion batteries”
        • Physiology or Medicine: “for their discoveries of how cells sense and adapt to oxygen availability”
        • Literature: ”for an influential work that with linguistic ingenuity has explored the periphery and the specificity of human experience”
        • Peace Prize: ”for his efforts to achieve peace and international cooperation, and in particular for his decisive initiative to resolve the border conflict with neighbouring Eritrea”
        • Economic Sciences: “for their experimental approach to alleviating global poverty”

        Notice how the problem described in the Economic Sciences prize is solving a problem using the scientific approach, just like it is for Physics, Chemistry, or Physiology or Medicine. It's not a discovery unlike most of the present year's other scientific prizes, but it is solving a problem like the Chemistry example. The Literature prize is for a work of human experience. The Peace Prize is for mitigating an ongoing conflict between countries.

        It's tiresome to get these weird pseudoscience criticisms - even if the field of economics really were strictly a study of human behavior as you claim (which it is not), you still have the matter that human behavior, contrary to assertion, can be scientifically characterized just like any other observable phenomena in the universe.
