What do pine cones and paintings have in common? A 13th century Italian mathematician named Leonardo of Pisa. Better known by his pen name, Fibonacci, he came up with a number sequence that keeps ...

A Fibonacci sequence goes like this: 1, 1, 2, 3, 5, 8, 13, 21, 34, 55 and 89. Each successive number is the sum of the two preceding numbers. So 1+1 =2 and 1+2=3 and 2+3=5. The scales on a pinecone, ...

Trying variants of a simple mathematical rule that yields interesting results can lead to additional discoveries and curiosities. The numbers 1, 1, 2, 3, 5, 8, 13, 21, 34, and 55 belong to a famous ...

Do you see the pattern? Each number in the series after the first two numbers is the sum of the preceding two numbers. So 55 is just the sum of 34 and 21, and so on. You can carry the sequence on for ...

Imagine the market is like a massive rubber band. When stretched too far in one direction, it must inevitably snap back, or retrace, before moving forward again. The challenge for the individual ...
