The Fibonacci series is an incredibly harmonious sequence of numbers discovered by the Italian mathematician Leonardo Pisano Fibonacci. Each number in the sequence is added to the previous number to give the new number. The series is like this: 1 1 2 3 5 8 13 21 34 55 89 144…
If you divide each number by the previous number, you will find phi, 1.618. We also call it the golden ratio. The Fibonacci series comes from the Egyptian pyramids to the Mona Lisa painting, from many harmonies in nature to music. If many masterpieces have been created by imitating nature in architecture and art, there is Fibonacci based on this.
Fibonacci’s soup is a very sweet mathematical meme inspired by the Fibonacci series.
