Lab Works in Applied ODEs

An annotated list of over 200 simulations in applied ODEs of various fields comes together with the Taylor Center software in a file Samples . (There simulations in Celestial Mechanics are especially numerous). However, there is no didactical material in that file.
The file Syllabi offers an annotated list of suggestions and ideas how to utilize those Samples for your lectures and include them into the respective courses and textbooks.

You have to download and install the software of the Taylor Center as
explained here. This software runs the
library of examples of various physical processes as real time animation in 2D
or 3D stereo for viewing via a pair of Red/Blue glasses.
(3D stereo appears on black background). If you do not have Red/Blue glasses, you
may watch it in conventional axonometry (clicking the respective button).
In order to learn and experiment with the simulations and real time animation
here, choose and click at the desired title in the list below. This will lead
you to downloading a zipped file. Unzip and place it anywhere preserving the
structure. It consists of a pdf file with a lecture and explanations
what to do and to expect, and several folders with the script files for the
software. While reading the pdf, when you decide to experiment with a
particular script file mentioned there, run the software and under File/Open
Script navigate to the desired script file (or follow the methods of
automation mentioned in the Appendix of the pdf files). Then Play it
putting the glasses on.
