`Fractal Foam'

Miniature, by Eden Phillpotts (1862-1960)

The grey beards wag, the bald heads nod
And gather thick as bees,
To talk electrons, gases, God,
Old nebulae, new fleas.
Each specialist, each dry-as-dust
And professorial oaf,
Holds up his little crumb of crust
and cries, 'Behold, the loaf!'

The graphic is the cover the November 14, 1992 issue of Science News, picturing the riddled basins of attraction of the triangle map. See also, The Jungles of Randomness: A Mathematical Safari by Ivars Peterson.

Material for high-school classes. (Lead author with teams consisting of Ross Cirincione, Brendan Foreman, Michael Harvey, Catherine Hollway, Earl Johnson, Scott Kersey, Melissa Rogers, Mary Pattison, David Singer, Ellen Stenson)

Math on File: Geometry is an invaluable curriculum-based and curriculum-enhancing resource. The problems are clearly and logically presented and will give your students a more concrete way of looking at geometry with real-world applications. This work is recommended as a required supplement for all high school geometry instructors. American Reference Books Annual 2004, entry 1542

Math on File: Calculus, part of a three-volume series that includes volumes on Algebra and Geometry, addresses five geometric categories: "Functions, Graphs, and Limits": "Differentiation and Applications": "Integration and Applications": and "Advanced Applications." ... Math on File: Calculus is an invaluable curriculum-based and curriculum enhancing resource. The problems are clearly and logically presented. I recommend this book to be a required supplement for all hight school calculus instruction. American Reference Books Annual 2005, entry 1535
