Hi, Doc. This is one of the best talks on the subject ever. I worked in the field for a few years but I gave up. Nobody working in cyber-physical/control systems has theoretical preparation in the subject. Most people have backgrounds in web development, or something else completely unrelated to timing. Tools like Ptolemy, Modelica and Simulink are not only unused, they are frowned upon. Maybe it's different in the States.
Excellent talk. Note that control engineers have been looking at these problems for many years, e.g. for embedded system timing read Motus & Rodd (1994).
This is such an excellent talk! I loved the part about not being able to execute multi-threaded software, because it will simply break the RT timing constraints.
I have published a paper that proves that any set of deterministic models that is rich enough to include Newton's laws together with discrete phenomena (like collisions) is incomplete. It does not contain its own limit points. So if physics is rich enough for these two things, then nondeterminism is unavoidable. See ptolemy.berkeley.edu/projects/chess/pubs/1183.html

This is an excellent talk. I noticed some abrupt interruptions. I hope we did not miss any important information
Excellent talk, thanks Mr Lee

How can one know, if the universe is not deterministic?
