  1. Circumstantial evidence on Mystery Company Recruiting Talent With a Puzzle · · Score: 2, Interesting

    Without even solving the puzzle, but reasoning purely on circumstantial evidence, the answer has to be Mike Hunkapillar's stealth startup Pacific Biosystems. The reasons are simple ... (1) PB's genomic technology is producing a flood of raw data, (2) PB therefore needs programmers to convert that stream into IPO-salable value, and (3) PB is the only one hiring right now!

  2. Mark Twain's "Man Without a Conscience" on Scientists Find 'Altruistic' Center of the Brain · · Score: 1

    Mark Twain wrote of a man lacking a conscience in The Facts Concerning the Recent Carnival of Crime in Connecticut:

    ... "Out of this with your paupers, your charities, your reforms, your pestilent morals! You behold before you a man whose life-conflict is done, whose soul is at peace; a man whose heart is dead to sorrow, dead to suffering, dead to remorse; a man WITHOUT A CONSCIENCE! In my joy I spare you, though I could throttle you and never feel a pang! Fly!"

    She fled. Since that day my life is all bliss. Bliss, unalloyed bliss. Nothing in all the world could persuade me to have a conscience again. I settled all my old outstanding scores, and began the world anew. I killed thirty-eight persons during the first two weeks--all of them on account of ancient grudges. I burned a dwelling that interrupted my view. I swindled a widow and some orphans out of their last cow, which is a very good one, though not thoroughbred, I believe. I have also committed scores of crimes, of various kinds, and have enjoyed my work exceedingly, whereas it would formerly have broken my heart and turned my hair gray, I have no doubt.

  9. What John von Neumann thought on On the Future of Science · · Score: 1

    It is by no means impossible for thoughtful people to predict the future with impressive accuracy. As evidence, here are some challenges for America that scientists and diplomats foresaw in 1955, from the book The Fabulous Future: America in 1980:

    C. P. Taft: We may not be able to prevent localized wars in the coming quarter-century---even ``hot'' wars in which our military forces will have to participate. Southeast Asia is the most dangerous spot, again because of the Chinese. The difficult problem there, as in every area, if to build character, honesty, and responsibility as well as the ordinary know-how of political method in the leaders of small new nations. These qualities are earned, not given; we tend to forget how recently---only seventy years ago---corruption was widespread in our own public life in Washington.
    Earl Warren: For as long as the U.S. leads the forces of freedom in the world's great ideological struggle, our institutions will be under a global spotlight, and what we do will speak much louder than what we say.
    John von Neumann: All major weather phenomena [...] are ultimately controlled by the solar energy that falls on the earth. [...] "The carbon dioxide released into the atomosphere by industry's burning of coal and oil---more than half of it during the last generation---may have changed the atomosphere's composition sufficiently to account for a general warming of the world by about degree Fahrenheit. [...] Intervention in atmospheric and climatic matters will come in a few decades, and will unfold on a scale difficult to imagine at present. [...] Such actions would be more directly and truly worldwide than recent, or presumably, future wars, or the economy at any time. [...] All this will merge each nation's affairs with those of every other, more thoroughly than the threat of a nuclear or any other war would have done. [...] What safeguard remains? Apparently only day-to-day---or perhaps year-to-year---opportunistic measures, a long sequence of small, correct decisions. And this is not surprising. After all, the crisis is due to the rapidity of progress, to the probable further acceleration thereof, and to the reaching of certain critical relationships. Specifically, the effects that we are now beginning to produce are of the same order of magnitude as ``the great globe itself.'' Indeed, they affect the earth as an entity. Hence further acceleration can no longer be absorbed as in the past by an extension of the area of operations. [...] The most hopeful answer is that the human species has been subjected to similar tests before, and seems to have a congenital ability to come through, after varying amounts of trouble.
    C. H. Greenwalt (DuPont CEO): How is mankind to supply its ever-increasing requirements for energy? [...] Over the years, many have forecast the exhaustion of our sources of coal and oil. [...] It seems quite certain that they will be exhausted someday, and it is essential for our survival that we be ready with as good an alternative as possible. [...] There is much talk these days about atomic energy as the answer to this problem. So it may be, [but] I am inclined to think that atomic energy, while important, will be only an interim solution. What we must devise eventually is some way of utilizing more fully the energy that comes to us from the sun. [...] The solution of the solar energy problem cannot fail to be of more lasting benefit to manking [than atomic energy]. Today, the best thermal efficiency that we can obtain in growing our crops is perhaps a few tenths of one percent of the energy the sun lavishes on the land. If this could be increased by a factor of ten, the problem of energy and food would be solved for many hundreds of years to come.

  13. Our suborned Mac G5 backup computer on Mac users 'too smug' Over Security? · · Score: 1

    The backup computer for our UW Quantum System Engineering Group is a Mac G5. It was suborned and used to attack NASA computers. As a result, the FBI subpoened the entire contents of the computer (Agents came by and cloned the entire disk at the digital level, and yes, we verified their credentials.).

    In response to this, our QSE Group decided that we would run a completely open research group. This makes it much simpler for both attackers and friends to learn what we're up to: just go to http://www.mrfm.org/ .

    Until you hire a 24-hour security guard, and have no physical connection of your computer to the outside world whatsoever, you are not secure against a determined, professional attack.

    More broadly, we tell entering students that if you want to keep a secret, don't tell anyone, don't write it down, and definitely don't store it on a computer. As the FBI agent told us: that's the only security plan that's guaranteed to work and affordable by anyone.

    Yikes! What to make of this?

    The history of the Jamestown Colony is instructive, because the USA treats its scientists and engineers much like the Jamestown colonists. The colonists were told by their British investors to focus mainly on prospecting for gold, not on the mundane tasks of farming. Result: not much gold was found, few crops were raised, and the members of the colony starved.

    Similarly, American scientists and engineers are told by their funding agencies and corporate employers to focus on breakthroughs. Result: not too many breakthroughs, very few new commercial products, and the economy is foundering.

    The Chinese are quite open about their strategy of balancing research and engineering more equally. And they make no secret of their intent that this strategy will eventually yield, first, economic dominance, then military and cultural dominance, in accord with the classic Chinese strategy "deceive the sky to cross the ocean".

    The point being, the Peace Corps is definitely *not* for people who are wondering what to do with their lives. Life in the third world is *much* tougher than ordinary life, and in many respects is much tougher even than life in the Marine Corps.

    This is especially true if you sincerely want to make a difference. Most likely, the third world will chew you up and spit you out.

    Here are total doctoral degrees by US citizens (or permanent residents) for the years 1995 and 2002.

    4. US PhD Mathematicians: 771 in 1995, 442 in 2002 (-> extinction in 2011).

    The physics and math communities, in particular, need to recognize that companies hiring few American engineers will be hiring no physicists or mathematicians. Conversely, the engineering communities need to recognize that in the long run, US companies need several PhD-level engineers to justify employing even one physicist or mathematician.

    The present system is like an ecosystem with plenty of sea otters (the physicists and mathematicians), but far too few abalone (the engineers). All very beautiful, no doubt, except the young sea otters starve to death. Meanwhile, the senior sea otters -- who are in secure possession of resources protected by tenure -- are slow to recognize that an extinction-level event is underway.
