GEOMETRY IN ACTION - DAVID EPPSTEIN

http://www.ics.uci.edu/~eppstein/geom.html

Areas in which ideas from discrete and computational
geometry - mainly low-dimensional Euclidean geometry -
meet some real world applications. There are brief
descriptions of those applications and the geometric
questions arising from them, as well as pointers to
Web pages and other sources of further information.

Topics include:

- architecture
- computer aided design/manufacturing
- computer vision
- geographic information systems
- graph drawing
- medical imaging
- origami
- textile layout

and many more.

MORE WEB RESOURCES FOR KNOTS

UNTANGLING THE MATHEMATICS OF KNOTS - MegaMath
http://www.c3.lanl.gov/mega-math/workbk/knot/knot.html

A hands-on exploration of the fundmental ideas of Knot
Theory, with a variety of activities for exploring knots
made from pieces of rope. Students can make and verify
observations about knots, classify them, combine them, and
find ways to determine whether two knots are alike. The
activities outlined can be combined to form a single lesson
about mathematical knots, or a larger investigative unit
that extends over a longer period of time. The sequence in
which the activities are listed is roughly in order of
increasing difficulty and challenge, but all of the earlier
activities are not strict prerequisites for the later ones.

THE KNOTPLOT SITE - Robert Scharein
http://www.cs.ubc.ca/nest/imager/contributions/scharein/KnotPlot.html

A collection of knots and links, viewed from a partly
mathematical perspective. The images were created with
KnotPlot, a program designed to illustrate and manipulate
mathematical knots in three and four dimensions. Browse the
picture gallery and read a description of KnotPlot's
features.

KNOTS ON THE WEB - Peter Suber

A comprehensive list of knot resources on the Web, annotated
and organized into four categories: knot tying, knot theory,
knot art, and knot books.
