Abacus: The Art of Calculating with Beads
The abacus is still in use today by shopkeepers in Asia and "Chinatowns" in North America. The use of the abacus is still taught in Asian schools, and some few schools in the West. Blind children are taught to use the abacus where their sighted counterparts would be taught to use paper and pencil to perform calculations.
One particular use for the abacus is teaching children simple mathematics and especially multiplication; the abacus is an excellent substitute for rote memorization of multiplication tables, a particularily detestable task for young children. The abacus is also an excellent tool for teaching other base numbering systems since it easily adapts itself to any base.
The enduring interest in this ancient device is evident by ever increasing number of visitors to these pages from all around the world.

Symmetry and Pattern: The Art of Oriental Carpets
Oriental carpets have long been appreciated for their beauty. That beauty is achieved through the choice of colors and designs, as well as by the manipulation of designs and colors to form pleasing patterns.
Patterns in Oriental carpets are never quite what you expect - a surprise here, a flourish there, a change of color, the flip or rotation of a design where you might not predict it. The more you look, the more variations you will find.
How can we explain this phenomenon? Is it the result of human choice, or human error?
The study of symmetry offers one approach to analyzing patterns in Oriental carpets. Through symmetry analysis we may identify areas of pattern that exhibit expected repetitions, and areas that vary from that expectation.
