In mathematics, the Fibonacci numbers or Fibonacci series are the numbers in the following integer sequence: 0,1,1,2,3,5,8,13,21,34,55,89,144… The sequence is named after Leonardo Fibonacci, who, in his 1202 book Liber Abaci, introduced the sequence to Western European mathematics.
This particular sequence has gained popularity due to some amazing features. For instance, the famous Fibonacci spiral, which is an approximation to the golden spiral appears all around nature.
Interestingly, Fibonacci numbers can be useful in certain fields. For instance, there are problems in biology, which are solved by using these numbers, such as the famous rabbit reproduction problem. Fibonacci numbers are also found useful in stock market analysis and some other fields.
In a recent TED talk Arthur Benjamin focuses on the aesthetic side of Fibonacci numbers. So check out this fun video, and, as always, for more videos, head to the TED YouTube channel.
