Educational Notes
0, 1, 1, 2, 3, 5, 8, 13, 21, 34…This may seem like a random string of numbers, but like with this pineapple, there’s more than meets the eye! These numbers are the beginning of a sequence of numbers called the Fibonacci Sequence after Italian mathematician, Leonardo Fibonacci, who described these numbers in his book Liber Abaci in 1202. You might wonder what a bunch of numbers have to do with a pineapple—quite a bit, actually! The pattern of this pineapple is a physical representation of how the Fibonacci Sequence works. Each number in the sequence is determined by the two numbers before it. So, 0+1=1, 1+1=2, 1+2=3, 2+3=5, 3+5=8, 5+8=13, and on and on to numbers that can’t even be counted to! If you were to block out these equations in a grid and draw a spiral starting in the middle and work your way out, you would end up drawing the same spiral found in the formation of this pineapple. This spiral is known as the Golden Spiral and can be found in many other places in nature such as the flowering of an artichoke.
