This book on symmetric geometric patterns of Islamic art has educational, aesthetic, cultural and practical purposes. Its central purpose is to bring to the attention of the world in general, and the people of Islamic culture in particular, the potential of the art for providing a unified experience of science and art in the context of mathematical education. Unlike other books on Islamic patterns, this book emphasizes the educational potential in the context of modern physics, chemistry, crystallography and computer graphics. The symmetric structure of about 250 Islamic patterns is presented. Simple, but detailed original, unpublished algorithms suitable for modern computer graphics are given for the construction of two-dimensional periodic patterns. Endorsed by prominent experts from the fields of Physics to Systems and Cybernetics, this book promises to be a must-read, not only for specialised mathematicians, but also for students, graphic artists, illustrators, computer hobbyists, as well as the lay reader keen to explore Islamic art.Shipping Notes

Best paper towel holder
Color: Silver
Very easy to put together, very sturdy and works great! Holds the paper towel with no slipping or popping off and it does not move around on the counter because of the suction cups. Very satisfied with the purchase. Bought another for the bathroom and one for my mom.

Perfection!
Color: White, Color: White
Oh my! A design so simple but so effective! I had a towel holder but when I went to pull a piece off..it would hardly budge. I use jumbo towels(triple rolls from Costco)I would have to hold it. And it would only work smoothly when the roll was down some. Then it would spin too fast!🙄 This holder..nope..the suction cups are nice and strong..and when I pulled a piece off..the spin was perfectly smooth and calculated... and you can tear off the piece perfectly You can hear the spin movement. SOOO glad I bought this..yes..it is expensive for a towel holder BUT...it does EVERYTHING its supposed to do! In my book...worth it. Do not hesitate...it's a keeper! And the white is perfect for my bathroom...blends in beautifully. But the choices are nice for any decor.

Excellent for one-handed operation
Color: Silver
This one-handed paper towel dispenser is very good quality. The suctions cups work very well on a clean, smooth surface. Has a good solid feeling while pulling off paper towels with one hand. You might have a slight learning curve on to how to pull correctly. Pull the paper towel only just far enough out that there is still good tension on the towel. Then pull the towel downward and close to the roll. A little practice will be rewarded with satisfaction of this product! Comes in so handy when you have one messy hand and only your other hand to pull off one or several towels. If pulling several sheets at once remember to pull them straight outward, then pull the last sheet downward and close to the roll. No fuss removing the used cardboard roll and replacing with a new roll. Assembly is easy. The assembly instructions aren't good quality but the parts only fit together one way. The dispenser will end up looking like a two-tier spoon carousel with the spoons hanging upside down. I would buy this as a gift for family or friends.

Sticks to the counter like superglue
Color: Silver
This paper towel holder definitely sticks to my granite countertop and wont move. I put it is a spot where that would not be a problem. If you need to move your papertowel holder daily, don't buy this one because you can barely pull it off the counter. But great product if you don't need to move.

works great
Color: Silver
I went through several towel holders but they did not unroll the towels smoothly. This one’s does. You can tear the paper towel off without a bunch coming undone. It’s very sturdy. Looks great by our kitchen sink. Only issue is if the A/c hits it in unravels, so we had to move it to an area where it was not hit by the A/C. Simple fix.
