Innovators Are Older Than Ever

GrokSoup writes "A new study shows that great achievements in science are produced by older innovators today than they were a century ago. Using data on Nobel Prize winners and great inventors, the author shows that the age at which noted innovations are produced has increased by approximately 6 years over the 20th Century. This runs contrary to accepted wisdom in science, which says that most scientists peak in their 20s. It is also welcome news to those of us who have not yet, ahem, done our Nobel-winning work."

In these articles, BA identified the rudder as the likely cause of two crashes (he's right), and he outlined his perception of slow response and stonewalling by both Boeing and the FAA. BA went on to win quite a few awards, including a Pulitzer, for these articles. In particular, BA chastised Boeing for not moving rapidly to correct the rudder problem.

      But BA's articles missed some critical, absolutely critical analysis:
      • airplanes are stupendously complex. They are perhaps the quintessential example of "if it ain't broke, don't fix it."
      • the 737 is a safe airplane. When BA flew out to accept his Pulitzer, he could not have been safer on any plane other than a 737, even with the original rudder.
      • the 737 had a known, rare, failure mode, which flight crews were trained to deal with.
      • correcting this flaw hastily could easily have introduced new flaws that were not known or understood.
      • In fact, the "Do Something!" imperative offered by BA's articles could, quite conceivably, have made the 737 more dangerous.
      It may be the case that Boeing and the FAA could have behaved better --- but Acohido's articles revealed a tremendous lack of understanding of objective safety statistics. The public was ill served by the accolades that Acohido received for his articles.

In her school they taught a bit of algebra, geometry, trig, calculus every year, starting in 8th grade. This idea (of doing some concepts from all topics each year) is a much better plan than doing an entire year of 1 topic each year. By the time she graduated from high school for example, she had taken the equivilent of the following US college science and math courses: Advanced Calculus, Physics (with Calc), Organic Chemistry 1 & 2, Inorganic Chemistry, and Advanced Biology. When she went on to do a Zoology degree, she did not have to repeat any of those classes, since she had already completed them. Interestingly enough, when she went back to school in the US many years later (to get a Vet Degree) they made her take 30 hours of intro courses (most of those I listed for instance + freshman english) and needless to say, she got a strong A in all of them :-)

One of the problems with the way I was taught quantum is that we were taught how to solve specific problems, but not how to approach these problems in general.

You sure won't be able to recall the most intricate details of what you're studying right now three years down the road, but you'll at least know where to look.

  18. Speaking as an inventor by DanielMarkham · · Score: 3, Insightful

    who just celebrated his 40th birthday, I for one welcome our new geriatric intellectual overlords.

    Seriously -- doesn't this make sense? 100 years ago you went around and dug in some rocks and junk piles and you were discovering stuff. Put a magnifying glass on a drop of pond water and it's a whole new world. Nowadays the _baseline_ for inventions has grown much more than before.

    For instance, my invention deals with measuring how well intellectual processes are being performed at an organization. To get to where I'm at, you have to first invent IP, then process control, then computer technology, etc -- and for me to come up with it I had to understand enough of that previous work to mutate it into something useful for people.

    What concerns me is that with more and more specialization, there seems to be a dearth of "cross pollenization" among sciences. Sure, there are specific programs, but it's almost impossible to find people with a truly broad and moderately deep general knowledge of sciences. My opinion only -- we've got a lot of brillant people but lack enough people who think outside the box and put the pieces together.

    Gee this is a wonderful submission. People are supposed to discuss the topic an abstract with about 10 sentences, unless you want to buy it for $5.

    Can't the guy do a little more research to post some other like articles that we don't have to pay for?

    Well, I guess no one RTFAs anyway so maybe this isn't any different.

  21. lots of reasons by bcrowell · · Score: 5, Interesting
    I can see lots of reasons why this might be true:
    1. They claim a shift of 6 years over the course of a century. Well, life expectancy has gone up a lot in this century.
    2. Big Science didn't exist 100 years ago. Today, you have people publishing papers in particle physics with 100 names on them. So out of those 100, who gets the Nobel Prize? The guy who's old enough to be the leader of the project.
    3. In certain fields, such as string theory, it just takes a really long time to learn enough mathematics to be able to start working on it. String theory is an extreme example, but, e.g., physics majors today learn Maxwell's equations at age ~20, but when Maxwell did his work in the 19th century, it was cutting edge math, and he was actually known more as a mathematician, not a physicist.
    4. In 1900, it was normal for people to get a PhD at, say, age 26, and go straight into research. Today, a PhD usually takes about 5-9 years, and then after that you end up doing a string of postdocs, say 1 to 3 postdocs at 2-4 years each. So you're maybe 34 by the time you even have your first faculty job.

    I think there's definitely a certain type of mathematical/scientific work that is most likely to be done by someone very young. A classic example would be the three groundbreaking papers Einstein published in 1905, at the age of 26. Nobody else had the guts or the mental flexibility to come up with relativity, or the photon theory.

    But then again, you have, say, Andrew Wiles, who proved Fermat's last theorem. That's a project that took many years of intense work in total solitude, and a young person just wouldn't be able to do it without committing professional suicide -- Wiles could do it because he had tenure, and could afford to fail.

  22. Logic vs. Intuition by bowloframen · · Score: 2, Insightful

    There was an interesting article on this topic on Slate (http://www.slate.com/id/2082960) two years ago. The article points out that the stereotype of the mathematician as a youthful prodigy is no longer the rule but the exception. It includes an interesting quote by mathemtician Henri Poincaré: "[L]ogic and intuition have each their necessary role. Each is indispensable." By logic, I'm guessing he means a more deliberate method of arriving at an answer, something that does require those years of learning and research, while intuition refers to that singular moment of clarity, the very thing that might've struck a twenty-year old mathematician a hundred years ago. So what's changed? Like Poincaré says, both are indispensable. You can stay in school for twenty-years, memorizing every theorem, every proof, every fundamentals of mathematics to heart, but if you don't have the capacity for intuition, you are never going to come upon something new. Likewise, even if the potential for greatness is in you, you won't be able to achieve it without first laying out your foundations. And that's all there is to it. There's simply more to learn, and without that learning, you'll never have a chance to exercise your intuition.

    I think one of the reasons for the increase in age is , as pointed before, there is a to understand and developing intuition with subjects far removed from everyday experience does take time and effort.

    The other main reason is these days science requires big resources to test an idea or investigate a concept. For example 1984 Physics Nobel prize was given to Carlo Rubbia and Simon Van der Meer for "their decisive contributions to the large project, which led to the discovery of the field particles W and Z, communicators of weak interaction". Carlo Rubia was not the actual discoverer but he was the project leader and it was his idea (Simon Van der Meer was the project leader in the accelerator side) and he was the one who puffed and puffed until everything got build. You have to be pretty senior and with credentials to go around puffing and getting people to take you notice.

    If you take another example.. the invention of the transisor by John Bardeen, William Shockley, and Walter Brattain, scientists at the Bell Telephone Laboratories. Other scientists in the early 1900s had seen the effect but they had not suceeded in reproducing the effect. It took a company with great resources for them to have everything necessary to make it work. I think the purity of Germanium being one. Again to have such a previldge position at a young age is pretty rare.

    Even Isaac Newton.. he was young when he came up with the tools he required for creating the models.. but it took him a good deal of 20years after that for everything to actually fall in place and for Principia to be written. If you read James Gleick's biography you can see his confusion and the mighty struggle he has. Apart from trying to understand the physics behind it he has to develop a method of investigation which today we take for granted. Slowly, as he is being pushed by his critics, he irons out the wrinkles in the work.

    Cheers, A.
