It's certainly reasonable to ask presenters to post their abstracts,
some may have done so already.

I welcome this presentation. By age I'm the last of the engineers who
might have even SEEN analog computers in use. I operated one and saw
another in use to model a chemical plant. These are a different world of
computation from digital logic.
I suggest anyone interested in this talk, do a quick read about
"differential equations" first. That's the equivalent of telling someone
"learn Boolean logic before looking at TTL circuits". If that's too
abstract, look up how a pendulum works, a bouncing ball, stuff like that
are all differential equations at work.
