The Fibonacci number sequence and Phi (the Golden Ratio) are math thingy things that don't get mentioned enough. They pop up everywhere without being noticed, in science, nature, politics, religion, art and behind the sofa.
What is the Fibonacci number sequence? I hear you ask.
The Fibonacci Sequence is the series of numbers: 0, 1, 1, 2, 3, 5, 8, 13, 21, 34, ... The next number is found by adding up the two numbers before it.
The Golden Ratio is when we divide a line into two parts so that:
the whole length divided by the long part
is also equal to
the long part divided by the short part
It is 1.6180339887... It relates to the Fibonacci sequence in that if you divide any number in the sequence by the one before it comes to this ratio and the further down the line is ne you go the closer it gets.
As a runner do you recognise that number? The 1.618... It's near the conversion rate for miles to Kilometers. So if you want to convert miles to km quickly take any number in the Fibonacci sequence, take that as miles, and then the next number (the sum of the last two numbers) will be the equivalent in km.
The higher you go the more accurate it is...
