December 9, 2021- Having supervised three mathematic classes, the past 1 1/2 days, one of my favourite concepts comes to mind. The Fibonacci sequence, devised by Leonardo of Pisa (aka Fibonacci) in 1202, was one of the harbingers of the Italian Renaissance, bringing Indian mathematical concepts to a European forum. Leonardo Bogollo was the son of Bonacci Bogollo-thus his nickname, Fibonacci (“fi” being short for “son of”).
The process is actually quite simple. Starting with the number 1,(though some mathematicians begin with zero), each number is added to the one before it, in the series. Thus, 1+1=2; 2+1=3; 3+2=5; 5+3=8; 8+5=13; 13+8=21, and so on, through the infinity of numbers. The sequence also operates in a negative direction.
The sequence has uses in poetry and in music. In fact, the original device was used in organizing Sanskrit poetry. It may also be the structural device for an expanding tower, or for a pyramid built in reverse order. Further information on the Fibonacci Sequence may be found here: https://www.mathsisfun.com/numbers/fibonacci-sequence.html.
I’ve written a Fib based on the sequence… For those who say mathematics is useless in everyday life, it is obvious they have never had to cook, calculate a unit price in the grocery, of figure out a percent off sale price!!
