We are looking for a Maple Wizard to join our team, based in California. US citizenship is an absolute requirement. Please send me a message if you are interested or know someone who might be.

A list of small graphs with associated pictures and tables of
values of various graph invariants.

The graph invariants were made using Maple programs which uses
the networks and GraphTheory packages.

A picture presents some inequality conjectures between the graph invariants.

And so with this provocative title, "pushing dsolve to its limits" I want to share some difficulties I've been having in doing just that. I'm looking at a dynamic system of 3 ODEs. The system has a continuum of stationary points along a line. For each point on the line, there exist a stable (center) manifold, also a line, such that the point may be approached from both directions. However, simulating the converging trajectory has proven difficult.

I have simulated as...

Tests are learning, not just inspectors.

I saw a fun blog post today from someone who plotted the Batman symbol within Maple. Enjoy!

All 19 chapters updated Mapler in elementary mathematics will be posted on this site:

Russian teachers have met the workshop with enthusiasm. Even during the holidays.
For me, the enthusiasm - it's thousands of visitors.

SHA-0.3.zip includes a Maple archive and help data base that implement the SHA algorithm (SHA-1, SHA-224, SHA-256, SHA-384, and SHA-512).  The implementation is interpreted Maple, so will be considerably slower than a compiled routine, but these should be fast enough for likely uses in Maple.  For example

In 2010-2011, I persuaded tens of thousands of Russian and Ukrainian students and students in that Maple - a very useful thing.
Testimonials - the number of visits and thanks.
So I decided to resurrect some of my old sites.
Not just for history!

The first: Maple PoverTools.
