It's certainly reasonable to ask presenters to post their abstracts, some may have done so already. Brian L. Stuart said:
My early class is Analog Computer Basics. I plan to go though the basic idea of electronic computing without bits. The first few minutes will be a quick overview of key ideas in electrical engineering. The second segment will look at using operational amplifiers to create mathematical building blocks. The remainder of the presentation will go through an example of modeling a simple physical system and illustrating it on a Comdyna GP-6.
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. Herb change is good -- Herbert R.
