Great posts, Doug and Hal! I've thought for some time now that today's
science is amazing in terms of some of the approaches and techniques being
implemented. However, if the same effort that is put into developing new
instruments, techniques, and methods of data collection is put into
revamping the ways in which science is communicated, then we might see some
real change in terms of lifting the profile of science in the minds of the
general public and the less informed. Unfortunately, I don't think more
"discoveries" alone, even impactful ones, will do it, not in today's world.
I have seen some interesting stuff (in terms of communication) on the Coral
List, with Jan Kuenzl's work coming to mind. I
