FE 'tkGooie' Utilities
A Menu of
Lorenz attractor orbits which are
often used as an example of 'chaos'.
This does not look like chaos to me
--- just continuous, smooth instability.
Chaos is comets crashing into planets.
Chaos is galaxies colliding.
Chaos is carpet bombing.
Chaos looks more like Brownian motion.
This is not chaos. Mathematicians,
please use another term.
For example: 'instability'.
Don't be so overly melodramatic.
The 'chaos' terminology just seems foolish
in many cases. Better to call this behavior
'furcation' or 'divergence',
rather than 'chaos'.

OVERVIEW of 'ODEtools'
A description of the FE 'tkGooies' system is available via a 'tkGooies' Description page. That page points out that the 'tkGooies' are a collection of utilities in categories (and toolchests) such as
Just below is a list of links to pages that present the source code of a collection of the 'ODE utilities' in the FE 'tkGooies' system.
Some sources (books, etc.) for ODE coding projects are shown in a section at the bottom of this page. These sources include equations, methods, and, in some cases, code.
Many of the books can be found in a university library (a real university, not one of those just-to-rip-off-the-student universities --- like Trump University). To aid in finding the book on library shelves, some library ID numbers are provided --- Library of Congress call numbers.

The following ODE utilities (to-be-done-with-Tk-GUI's) are on a 'to-do' list.

Use the list-of-links (above) to go directly to web pages that contain source code along with code-descriptions and screenshots.
The Tk script files (and other auxiliary files, if any) are in text files that can be down-loaded to your computer and implemented.
To download, simply 'right-click' on a text link and, in a popup window of your web browser, choose an option such as 'Save Link Target As ...'.
