Deepest apologies to Andy. This was supposed to go to a friend. I
overstated my remarks on Andy's seminar. He spoke about his photos
taken on a rotating turntable and gave a demo and photographed a
number of students and me. I was hoping he would discuss high-speed
photography, but I didn't give him very clear instructions on what
the students might find most useful in their research.
My friend and I once had a grant to study the effect of bursting
bubbles and the droplets thereby formed, which would fall back to the
liquid surface, generate more droplets that would hence be carried on
shore by the prevailing winds. These droplets, essentially salt
water, would then cause damage to plants not accustomed to being
bathed in salt water. Our focus was on the mechanics of bursting
bubbles and the subsequent processes as they fell back to the
surface. I wish I could say that it was successful.
Again, my apologies to Andy. The seminar was fine. If he cancels my
membership in photoforum, I won't blame him!

John,
ps: The Andy referred to is Andrew Davidhazy, a professor at RIT,
who specializes in high speed photography and who once worked in
research with Edgerton. I had him to UH to give what turned out to
be a not very good seminar. He has taken a lot of micro-
photographs of speeding bullets crashing through various objects as
well as droplets falling on liquid surfaces.

Here is a variation on the classic water drop photograph. Andy
may like this. Or not.
