Via this web page you may create a PDF book on rational mathematical modelling of dynamics tailored to the interests you specify. Currently this is an early draft version, an alpha version.

Among the sections that follow, choose the interesting ones

At the end click Submit to process, typeset and produce a PDF book tailored just for you. The processing automatically detects all prerequisite sections and includes them as well. Only select what interests you.

But first, what computer algebra package do you prefer?
Reduce (recommended)
Maple (as yet only available in Chapter 1)
Mathematica (as yet only available in Chapter 1, thanks to Rick Eller)

Enter the magic word "p o s s u m" into then for processing and typesetting.

Wait for perhaps five minutes or so for the results page to load---the results page will load only after the book has been typeset (or failed as the case may be).

Print the book 2up

The book is typeset onto A5 pages (in colour) so please save forests and print two pages per sheet of paper. Also, A5 is by far the best standard size for reading electronically on your computer screen.
