Geometry
 Websites presented in alphabetical order Archimedes' Laboratory 
 Inspired by the work methods of scientist Archimedes, this online companion to the print magazine of the same name provides a virtual lab of geometric puzzles to make and solve, games, mazes, and optical illusions. Appropriate for children and adults. Searchable. Available in English, Italian, and French. http://www.archimedes-lab.org/indexB.html Topics: Games & Puzzles, Mathematics, Mysteries and More Last updated Jun 24, 2003 Euclid of Alexandria
Biography and contributions of "the most prominent mathematician of antiquity" and author of the classical treatise "The Elements." Includes a bibliography, cross-references to related topics, and a list of "Mathematicians born in the same country." http://www-history.mcs.st-andrews.ac.uk/Mathematicians/Euclid.html Topics: Mathematics, Nonfiction by Genre, Notable People Last updated Mar 30, 2005 Euclid's "Elements"
An exploration and explanation of the 13-volume treatise "Elements," Euclid's contribution to geometry and "one of the most beautiful and influential works of science in the history of humankind. Its beauty lies in its logical development of geometry and other branches of mathematics." Created and maintained by a mathematics and computer science professor. http://aleph0.clarku.edu/~djoyce/java/elements/toc.html Topics: Literature & Books, Mathematics, Nonfiction by Genre Last updated Jun 26, 2005 Fibonacci Numbers and the Golden Section
A fascinating site with mathematical and geometrical facts as well as formulas, history, and diagrams. Find explanations of Fibonacci numbers, methods for constructing golden sections in two or three dimensions, and information about the golden section (or mean or rectangle) in architecture, art, and music. http://www.maths.surrey.ac.uk/hosted-sites/R.Knott/Fibonacci/fib.html Topics: Mathematics, Mysteries and More Last updated Oct 15, 2009 Geometry From the Land of the Incas
This noisy, colorful, and completely unusual site is an eclectic mix of sound, science, and Incan history intended to interest students in Euclidean geometry. Includes geometry problems, quizzes, quotations, scientific speculation, and more. http://agutie.homestead.com/ Topics: Mathematics Last updated Dec 4, 2002 Great Circle Calculator
A useful site for calculating direct line distances between any two points on the globe. Enter the latitude and longitude to find the length "as the crow flies" of the arc between the two locations. Distances are given in miles and kilometers. http://www.gb3pi.org.uk/great.html Topics: Mathematics Last updated Oct 15, 2001 Great Circle Mapper
A site for generating maps of great circle routes (shortest paths between two points on a sphere's surface; technically geodesic paths when referring to the earth) and related information. This hobbyist site warns that its information "may not be accurate or current and is not valid for navigation or flight planning," but armchair aviators will still find it fascinating and educational to plot maps by paths, ranges, air speed, and other aeronautic measurements. http://gc.kls2.com/ Topics: Mathematics Last updated Nov 6, 2002 Origami Mathematics
Information on the mathematics of paper-folding, including the geometry and origami axioms formulated by Italian-Japanese mathematician Humiaki Huzita. The section "Five Intersecting Tetrahedra" presents construction instructions and other types of models. "Notes for an Origami/Combinatorial Geometry Course" (a course offered at Merrimack College, North Andover, Massechusetts), a gallery, and annotated links are also provided. http://kahuna.merrimack.edu/~thull/origamimath.html Topics: Crafts, Mathematics, Notable People Last updated Jun 9, 2008 |
