What do bunnies, cauliflower and sea snails have in common? A pattern based on the Fibonacci series (0, 1, 1, 2, 3, 5, 8, 13...) where each successive number is the sum of the previous two. The original problem that Fibonacci investigated in the year 1202 was how fast rabbits could breed . If you started with a pair of rabbits, how many pairs would you have in a year? This fascinating site reveals the complexities of nature's miracles. Don't miss it!

These nine magic tricks are based on simple mathematics and not on magic. Although to those who do not understand the mathematics, they may seem magical! There are card tricks, calculator tricks and geometry and topology tricks such as this. Challenge a friend to hold a rope in his hands and tie a knot in it without letting go of either end. The solution is really quite simple. Cross your arms before you grab the ends of the rope. When you uncross your arms, there will be a knot in the center of the rope.
