  1. The SSC was much cheaper than the ISN or moonbase on New 'Mystery Meson' Sub-Atomic Particle Discovered · · Score: 2, Insightful

    The price for building the SSC was a small fraction of the cost for even the limited International Space Station we actually built, much less the original planned ISN they kept in the budget the year Congress axed the SSC. Spending a few billion on the SSC, which was guaranteed to either give us the Higgs boson or prove the Standard Model wrong (the exciting if unlikely option) and thus provide some new basic science strikes me as a much better investment than tens of billions on the politically motivated ISN. I'm willing to invest money on real space science (Hubble, Galileo, many others), but too much money that supposedly for science goes to political stunts like the Moon landing instead of projects of actual scientific value. I'm not sure how practical generating power on the moon is and beaming power down has obvious security implications.

    For the poster who asked about how old the Standard Model is and why we haven't seen applications, the Standard Model was created in the 1970's so it's very young by physics standards. We're just beginning to deal with the implications of quantum mechanics for silicon chips and the basics of that area of physics were established in the 1920's. Technology lags physics by a substantial amount of time. However, the physics of particle accelerators themselves has led to enormous advances in medicine and manufacturing as such techniques are used to look inside the human body for disease as well as inside microprocessors for defects, so it's been far from useless even from a shortsighted perspective.

    • Greg Egan's Quarantine, Diaspora, Distress, and Permutation City

If you know a good used bookstore, I'd also highly recommend John Varley's short story collections (most published under several titles). He's not a bad novelist, but he's incredible in short fiction.

  7. Low hanging fruit on Human Accomplishment · · Score: 1

    As for the decline in achievement post 1800... that's probably because all the low-hanging fruit are gone.

    As we develop new areas of science and mathematics, we find new branches of low-hanging fruit of which we were previously unaware, so this statement is not true in general. For example, when Feynman and Schwinger figured out how to regularize quantum field theory calculations in QED (for which they received the Nobel prize), they made a wide array of previously unsolvable particle physics problems into low hanging fruit, generating a burst of research in the field for the next few decades.

    However, such opportunities are rarer in the arts. It's no surprise that someone like Shakespeare appeared during the particular time period when he wrote. He was lucky to be born at a time when the field of English-language plays was emerging and took advantage of that fact to pick plenty of the low-hanging fruit. The same is true for the other great Renaissance artists. Today's artists have to reach much higher to find any fruit.

    While the Taiwan giant TSMC dominates the ASIC production business (though they do build some of their chips in fabs in Oregon), Taiwanese companies don't have a similar level of market penetration into the microprocessor space.

The other microprocessor companies like IBM and AMD also manufacture many microprocessors in the US, though I don't know about their fab distribution as well as I know Intel's.

  16. Pipelines, Dollars, and Euros on Former Intel Engineer Pleads Guilty To Taliban Aid · · Score: 1

    The funny thing is, people were claiming that the war in Afghanistan was about oil, yet their only argument for that claim was that the US wanted this pipeline. Two years later, where's the pipeline?

    They're working on it. Multibillion dollar deals don't happen overnight, especially when they have to get three countries to agree on them and deal with an ongoing war in one of the countries.

    At the end of 2002, Afghan President (and UNOCOL consultant) Khamid Karzai signed an agreement with the leaders of Turkmenistan and Pakistan to begin building a 1500km trans-Afghan gas pipeline to Multan where it will join to an existing pipeline that will take it to a port in Pakistan. Here is a link to the story at the BBC. The preliminary cost of the project is $2-3.2 billion. I suspect that the lack of US control outside of the cities of Afghanistan is the reason that large scale construction hasn't begun.

    Why is the pipeline important? Well, it's estimated that 16% of the world's petroleum reserves are in the Caspian Sea region. Today, only a small amount of that oil and gas is extracted for use by nearby countries because there are no major pipelines to take it to the global markets. The best routes for a pipeline go through Russia, which the West doesn't want, Iran, which the West also dislikes, or Afghanistan and Pakistan. As the previous poster mentioned, UNOCOL gave up on the pipeline project in 1998. They couldn't get the Taliban to give them what they want. Afghanistan's government is quite different after the US invasion and wants to go ahead with the pipeline.

    There's another factor why the US is worried about control of Middle Eastern oil resources. Currency. Saddam made quite a profit when he started trading his oil in euros instead of dollars in 2000. Other OPEC countries like Iran are thinking about using euros instead of dollars. This may not seem important on the face of it, but the use of American currency as a standard medium of exchange is a great source of American power, one of the cornerstones of American dominance of international finance, as it was for the British before the World Wars. Other countries using dollars allows the US to export its inflation by printing more money and issuing treasury bonds at low interest rates and also helps the US to avoid facing the consequences of its large trade deficit.

Tim O'Reilly has some insightful thoughts on the true economic consequences of file sharing in his article Piracy is Progressive Taxation. I've quoted parts of the first two lessons, which I think are most relevant to this issue, below:
    Lesson 1: Obscurity is a far greater threat to authors and creative artists than piracy.

    Let me start with book publishing. More than 100,000 books are published each year, with several million books in print, yet fewer than 10,000 of those new books have any significant sales, and only a hundred thousand or so of all the books in print are carried in even the largest stores. Most books have a few months on the shelves of the major chains, and then wait in the darkness of warehouses from which they will move only to the recycling bin. ...

    Lesson 2: Piracy is progressive taxation

    For all of these creative artists, most laboring in obscurity, being well-enough known to be pirated would be a crowning achievement. Piracy is a kind of progressive taxation, which may shave a few percentage points off the sales of well-known artists (and I say "may" because even that point is not proven), in exchange for massive benefits to the far greater number for whom exposure may lead to increased revenues.

    Our current distribution systems for books, music, and movies are skewed heavily in favor of the "haves" against the "have nots."

    Lowering the barriers to entry in distribution, and the continuous availability of the entire catalog rather than just the most popular works, is good for artists, since it gives them a chance to build their own reputation and visibility, working with entrepreneurs of the new medium who will be the publishers and distributors of tomorrow.

And no, she isn't downloading Britney Spears, but forgotten bands from the 60s, 70s, 80s, and 90s, as well as their musical forebears in other genres. This is music that is difficult to find -- except online -- but, once found, leads to a focused search for CDs, records, and other artifacts. eBay is doing a nice business with much of this material, even if the RIAA fails to see the opportunity.
