There is an alternative view (which I subscribe to) that science is
_limited_ by technology rather than driven by it. Many areas of work
were inaccessible before the advent of the electron microscope for
The "technology driven science" you describe implies a passive
relationship between science and technology. In my view, technology is
more often developed to meet a particular scientific need. This does
not, of course, preclude serendipity.

I confess to never having seen "Animal House", but I guess you are
saying that I stated the obvious. It is surprising how often people
overlook the obvious in pursuit of scientific knowledge. I was taught
the value of Occam's razor ...

Yes, I agree with you Stuart - One of my jobs, in the past, was to
develop an automated system for detecting weed seeds in batches of crop
seeds for OSTS at NIAB in Cambridge (UK).
I thought it was an appropriate application of image analysis and
computer technology to an area of work that was tedious and boring.
The people employed as seed analysts were not quite so convinced and
saw the development as a threat to their jobs.
In fact, I succeeded in convincing the seed analysts that the
technology was just a way of reducing the most tedious aspect of their
work by screening samples and it could *improve* the quality of their
Sadly, at the time, the computer technology needed to accomplish the
task was not available at a cost that would justify it's use, and the
technology we could afford was inadequate. However, I think that
similar work is presently underway in the statistics department at
Edinburgh University supervised by Colin Aitken and Mike Talbot.
If anyone is interested (!) part of this work is described in: Travis,
