Most of t...You know, I think that Rees is correct. Most of the really exciting science happens through a combination of two things: (1) really painstakingly careful research, and (2) a fundamentally new insight into a system. (For engineering research, the second could be modified to something like 'a fundamentally new application for a system'.)<BR/><BR/>True, most of these seem obvious and 'waiting to happen' in retrospect, but much of the work is subtly based on the milieu surrounding the researcher; the conferences they went to, little tidbits of shared information/data, tiny procedural modifications, etc. Now, this means that a new initiate into science won't know enough or have enough of a 'web' of connections to make a truly brilliant discovery... but it also means that the older scientist will be faced with a lifetime of thinking in a certain way, invisibly constrained by assumptions that may not be wholly accurate. The older scientist simply doesn't have the flexibility of thought - whether due to being in a 'rut' or an honest physiological issue with neuronal plasticity - to make the truly innovative discoveries.<BR/><BR/>That being said, there is plenty of space for older scientists to be productive members of a research team. First, their expertise and experience may be invaluable. While they may not be well-acquainted with the very best up-and-coming technology, they will generally have a very good and fundamental understanding of technology that was new when <EM>they</EM> were first starting. The experience that comes with painstakingly troubleshooting a recalcitrant protocol is invaluable, as it gives insights into the way the system really works. (A classical example I recently noticed was that molecular biology - which used to be done largely by hand - is now carried out entirely using premade 'kits'. Young researchers using these kits rarely actually understand every procedural detail of what they're doing, then, often resulting in subtle but critically important oversights.)<BR/><BR/>Thus, older researchers can be good mentors and collaborators. They can lend their experience to the younger generation. They also are generally quite good at critical reading of new research, and can be used in that capacity. For true innovation, though, most people need to look at the younger generation of researchers.<BR/><BR/>One point that may support your contentions, though: the way science is structured today means that older faculty are generally not doing much labwork, particularly the bright and successful ones. After getting a postdoc, young researchers generally spend most of their time working on grants and advising, rather than real work. Pre-tenure, they often spend a lot of effort on directing individual projects and getting the lab established in a new field. Afterwards, though, once the lab is larger and more settled (call it early 40s for most researchers), they spend less and less time on specific projects, and more time obtaining funding and administrating the whole lab. Thus, the system may preclude much faculty innovation past the early 40s.<BR/><BR/>*shrugs* An interesting issue.Enderhttps://www.blogger.com/profile/08124430514659588154noreply@blogger.com
