My new book, Shape, comes out this coming Tuesday, May 25! This book is about geometry: in it you'll find gerrymandering, pandemics, the foundations of AI, poetry, math/theology beefs of late-czarist Russia, championship-level checkers, the Talmud, why you are your own negative-1st cousin, wrinkles in time, and a lot more. It's not just about triangles (though there are some triangles in it.) The New York Times calls it "unreasonably entertaining," and there's an excerpt in this weekend's Wall Street Journal (paywalled.) Shape is available for preorder now at Bookshop and Amazon, and of course it will be at your local bookstore on Tuesday!
It's here! After a year, a new release of the free computational design development environment PUPPICAD. Almost 4000 visual programming modules available, with new advanced computational geometry modules added such as splines, contour cutting and convex hull generation. The full Windows Media3D namespace and the Helix 3D Toolkit have been converted into visual programming modules, so that you can do pretty much anything you can imagine. New mathematical modules for expression evaluation and matrix algebra are also available. Lots of example programs, and a quick-build menu for common geometry objects make it easier then ever to get started. This version can generate visual programming modules on the fly from .NET DLL files, so that users can expand features without having to write any code.
My friend Dan and I collaborate on mathy art projects! I throw ideas at him; he does all the hard work of the math and art; I get him to write down what he did, and I help photograph and edit. The blog is a mix of pretty pictures and detailed technical explanations — something for everyone. (Well, for everyone who really, really likes geometry.) So far: polyhedra, paper models, tractrices, reaction-diffusion systems, and bonus musical creations. Comments/questions/suggestions welcome.
