The Math-Art series, August update

“The Quaste quandary”, vol. nº 8 of the Math-Art series, is now available on the iBook store @http://bit.ly/JCDigitalBooks , GoogleBooks @http://bit.ly/JCGBooks . A black&white version is also available on Kindle @http://bit.ly/JCPublishing

This book, as well as vol. nº 7, “The Mathematical Surfer”,  features some of the works I produced at the beginning of the 12-30 project, month of January.

MathMod & Morenaments. Folium before it evolves in a trefoil curve. A folium is a parametric surface. Descartes put his signature on one, so did Kepler. Because it involves a polar equation – the pedestal on which the main folium stands is a visualization of that same object polar coordinates.
Background: A pgg symmetry. It is characterized by glide-reflections in two perpendicular axes and produces “double glide” patterns (pgg patterns)

MathMod & Morenaments.
This 3D parametric surface is attributed to programmer and mathematician Roger Bagula. I slightly extended the x parameter to emphasize the interconnection of the two volumes.
Background: P31 symmetry. This group has three different rotation centers of order three. It has reflections in three distinct directions.

MathMod & Morenaments. The Clebsch surface is a non-singular cubic surface studied by mathematician A. Clebsch (1871). Like all nonsingular cubic surfaces, the Clebsch cubic can be obtained by blowing up the projective plane in 6 points
Background: A p4 symmetry. A p4 tiling is symmetric under two- and four-fold rotations.
