Chu's Final Breakthrough Before Taking Office

KentuckyFC writes "While preparing for the job of US Secretary of Energy in the incoming Obama administration (and being director of the Lawrence Berkeley National Laboratory and a Nobel Prize winner to boot), Steven Chu has somehow found time to make a major breakthrough in the world of atom interferometry. One measure of an interferometer's sensitivity is the area that its arms enclose. Chu and colleagues have found a way to increase this area by a factor of 2,500 by canceling out the noise introduced by lasers, which work as beam splitters sending atoms down different arms (abstract). One thing this makes possible is the use of different types of atoms in the same interferometer, allowing a new generation of tests of the equivalence principle. (This is the assumption that the m in F=ma and the m's in F= Gm1.m2/r^2 are the same thing). Let's hope he's got equally impressive breakthroughs planned for his encore as US Secretary of Energy."

    You are right. Many researchers would not make a good manager. OTH, Dr. Chu is ALREADY director of the Lawrence Berkeley National Laboratory and doing a good job. I am guessing that he will do a bang up job as nation director. Far too often politicians bring in more politicians because they LIKE the person, not because the person is qualified to lead. In this case, Chu is not likely to be BSed.
    In light of the idiots that we have had directing the science world for the last 8 years (and to be honest even in Clinton and reagans terms), this is refreshing.

He didn't know what it was, researched it, and provided a definition for the benefit of others. That's being informative. Whining about how stupid it is to provide information because you're, admittedly, unfamiliar with the subject is flaming.

    I think this is even truer than it sounds. A lot of people Obama's tagged have very little incentive to take the position other than if they feel they might be able to get stuff done. All the good scientists I know mostly just want to work on cool and interesting things and see administration and bureaucracy as a necessary evil, making the aspects of these jobs which can be exploited for monetary gain less attractive than getting back to a lab. Furthermore, any career politicians in their positions would be ruined by going around the administration, whereas it's not like Steven Chu will ever struggle to find a job he wants. The upshot is that these guys have little to lose by being forced to resign, whereas it'd look horrible for Obama if they go off in a huff because he won't listen to them. Obama's been accused of talking change without having any substance, but I think he just hit the point of no return on following good science. It'll certainly be nice to see Nobel Prizes having more weight than Magic 8-Balls.

    There's two schools of thought when it comes to management:

    1. Managers should have experience in the field so they can make informed decisions based on their background knowledge.
    2. Managers should know how to manage and can rely on advisers to provide the technical information upon which they base their decisions

    And the thing is, neither school of thought is inherently right or wrong.
    It is totally dependent on the position to be filled and many can go either way.

    For example, Obama picked the 1st type of manager to be Sec of Energy, yet he picked the 2nd type to head the CIA.

    It's that lack of work more than ideology that got us in such a mess. These mistakes had little if anything to do with liberal vs conservative. (disclaimer - I am quite liberal)

    The war and occupation would have appeared a whole lot less stupid if they had actually been thoroughly planned.

    Deregulation may have weakened the safeguards of the financial system, but it didn't eliminate them; they just were ignored. That was negligence more than lazzis faire.

    The handling of Katrina was a tragedy and the treatment of the victims afterwords was a crime. Any other conservative with the power of the government at their disposal would have used that power to save lives.

    Say what you want, but the memo entitled 'Bin Laden determined to strike targets in the US' was ignored. Even if the attack could not have been prevented, the military and intelligence services could have been on high alert and emergency services on a higher alert. Lazy! Lazy! Fucking life threatening laziness.

    Then to completely throw the feeling of empathy the world had for the US into the trash. Was it policy, or was it just easier to act unilaterally? What a waste!
