Geometric Arts
http://geometricarts.googlepages.com/
A site dedicated to geometry and visual perception: patterns,
fractals, structures, rotations, spirographs, optical arts,
knots, and more. Some constructions include the artist's
reflections, instructions, and links to related sites and
interactive applets.
AAA Math
http://www.aaamath.com/
AAA Math, which we first featured in 2001, has launched
a Spanish language version of its site here:
http://www.aaamatematicas.com/
The site features online interactive lessons, exercises,
practice, and games about basic arithmetic concepts and
methods, for grades K8.
Topics include: addition, comparing quantities, counting,
decimals, division, estimation, factors, fractions, money,
multiplication, naming numbers, ordinal numbers, percent,
place value, positions, properties, ratios, and subtraction.
Fractal Music
http://www.brotherstechnology.com/math/fractalmusic.html
In 2003, Benoit Mandelbrot suggested to Harlan Brothers that he
undertake a rigorous treatment of the subject of fractal music.
Here is an overview of Brothers' subsequent research, including
papers, definitions, and examples.
Brothers offers a daylong workshop based on his work,
developed from a lecture and lab he first offered at Yale:
