2007 Physics Nobel Prize For Giant Magnetoresistance 111

Posted by kdawson from the google-thanks-you-too dept.
A number of readers made sure we are aware that the 2007 Nobel Prize in physics has been awarded to Albert Fert and Peter Grunberg for simultaneously and independently discovering giant magnetoresistance. This property has allowed the explosion of disk-space growth and is cited as being one of the first nanotechnology breakthroughs. From the announcement: "Very weak magnetic changes give rise to major differences in electrical resistance in a GMR system. A system of this kind is the perfect tool for reading data from hard disks when information registered magnetically has to be converted to electric current."

          This argument doesn't make sense to me, as flash chips are selling at much higher quantities than hard disks already. Flash MP3 players and embedded devices are everywhere, and the margins on flash manufacturing aren't that high. I suspect prices are being driven down as fast as technology is allowing them to, and that building more products based on them will only drive prices higher as supply outstrips demand.

      The development of spintronics allows many things, not just the hard drive read heads we've all had for the last 10 years. There are a couple of problems with flash, and if researchers can get the sizes down, these can be fixed with MRAM, magnetic memory based on spintronics again.

      Also, these are the applications we know about; as with any branch of physics, you have to give the physicists more than 20 years to figure out the physics, and then give the engineers some more time to explore what they can

        We've been moving away from mechanical storage for 60 years, ever since the first real computer appeared. Things have gotten less and less mechanical ever since then. But it's a slow, incremental process. Old tech doesn't just disappear because somebody invented something kewler. The new tech has to make an economic case for itself. I'd love to replace my hard disks with something solid state. But it has to be affordable and reliable. The closest thing we have is flash RAM, and that's not practical for anything bigger than a couple of gigabytes. And even then, I wouldn't rely on it for mission-critical data.

        Technology and economics aside, a paradigm shift would be helpful. As the OLPC's XO demonstrates, you can easily build a useful computer that doesn't have a hard disk. It just won't run all the bloatware that we're all so dependent on. OLPC's second-biggest accomplishment might be to force everyone to rethink the way our overpowered computers are designed.
        • Shut up with your useless drivel.

          Of _course_ you can build a computer without a HD. You can even build a computer without any kind of flash AND hd. Just put something on a floppy, and boot from it.

          What uses space nowadays aint "bloatware", but the increase in media.

          Yeah, back in the days you could get a few seconds of sampled sound. Later you got pictures. Later you got videos. Then 3D-Scenes.

That's all about cheap hard drives. I had a good friend fifteen years ago with hundreds of records - an incredible collection by standards of the day

      The cash grant amounts associated with the Nobel Prizes have an interesting history- the foundation wasn't granted tax-exempt status until 1946, so for some of its early years, the tax assessment on the fund exceeded the total worth of that year's prizes. That, combined with orginally very conservative investment rules, caused the nominal value of the cash grants to stagnate, and the real value against inflation to plummet.

Here we have a real, old-fashioned Nobel Prize : a simple and brilliant idea, an experimental demonstration, and practical applications, like in the 1900s were you had to demonstrate the effect in front of the Academy of Sciences in order to get the prize or even to get your paper published, look at the online lessons from the time (Lippman for instance). As a professor of physics I was on the commitee of a conference aimed at high school teachers about modern days physics. I suggested the teachers in charge invited Fert but they answered that they do not understand a single thing about spin and ironically enough they wanted conferences about string theory and particle physics instead : there is definitely something wrong with public outreach of science, astrophysicists and particle physicists having built PR machines on the scale of their accelerators, observatories and budgets, and grabbing a huge part of the grants, when, with the same budget than the CERN spent on condensed matter physics or (relatively) small budget experiments maybe we would have a thousand of discoveries like the one of Fert. I bet that in CERN maybe a physicist in a thousand, with an IQ over 200, sees the big picture and understands what the wotk is really about. Atomic, molecular or condensed state physics, fluid mechanics, soft matter physics, are much more tractable and practical with real challenges (high-TC supraconductivity...) Admiteddly the Web came out of CERN but still...

      If you want to equate the importance of physics with technological applications, fine, but that's not the only reason to do physics. Learning about the fundamental building blocks of the universe has intellectual merit of its own, and face it, a lot of ordinary people are really interested what physicists learn about such things. You seem to be arguing that people shouldn't be interested in particle physics or whatever, just because condensed matter is more practical. That's a value judgement.

      By the way, it's a fallacy to think that if not for Big Particle Physics, condensed matter physics would be enormously more fruitful. If the money wasn't going to accelerators, that doesn't mean it would be going to condensed matter physicists instead; it might just go to biologists.

      And just dumping money on condensed matter doesn't guarantee breakthroughs. There are already far more condensed matter physicists than particle physicists; if you try to buy even more of them, you're necessarily going to start scraping the bottom of the talent barrel, and you get diminishing returns. Unless you're arguing that the money should go to existing condensed matter physicists without expanding the talent pool, to fund work that they currently can't afford to do. Well, I don't buy that either: the guys most likely to make breakthroughs are almost certainly already well funded.

      I bet that in CERN maybe a physicist in a thousand, with an IQ over 200, sees the big picture and understands what the wotk is really about.

      That's highly unlikely. If you are a prof. of physics, as you claim, then you know very well what it takes to obtain a Ph.D., and one of the most basic requirements is the ability to demonstrate a very complete understanding of the relevant field and the "big picture" as you put it. And that's just for the degree; there's no WAY someone could get a faculty appointmen

There is a difference in between aligning the correct buzzwords in approximately the correct order (as many string theorists do) and producing a grand unified theory of quantum gravitation and of the other forces -at nonzero temperature of course- , for which one should have the brains of the lovechild of Einstein, Newton, Poincaré and a good dozen of mathematicians.

Oh, and I'll be sure to tell all the folks on hep-th to stop looking at QED since it's solved.

      I like to compare science choices to investments (stocks, bonds, derivatives, etc). They all have different risks and payoff profiles. It is possible that fundamental particle science may find a revolutionary breakthru that leads to worm-hole travel or anti-gravity engines. But the chance of that is relatively small compared to more practical research that you mention. But the practical stuff only produces incremental steps in knowledge. We may need the big breakthroughs for the quantum (sic) leaps in tech

      Irony is definitely thick: particle physicist would say that spin simply has to do with the irreducible representations of the Lorentz group of the special theory of relativity. Then they would keep on going about iso-spin, susy, confomal invariance, etc... It is not unheard of Dirac equation being also used in the area of

    • I agree that condensed matter doesn't get the PR that it deserves, which is the fault of condensed matter physicists. String Theory has so much press because people like Brian Greene and Kaku generated it. If you had people going out telling people how cool materials science can be, you could get the media's attention. But don't complain about funding, materials science gets much better funding than any other area of physics. Complaining about funding is wrong headed to the point where I would question
