The Golden Ratio:

(also known as the golden number, golden proportion or divine proportion)

<aside> 💡 It’s a ratio between two numbers that equals approximately 1.618. Usually written as the Greek letter phi, it’s related to the Fibonacci sequence.

• Euclid and other early mathematicians like Pythagoras recognised the proportion, but they didn’t call it the golden ratio. It wasn’t until much later that the proportion take on its mystery.
• In 1509, Italian mathematician Luca Pacioli published the book “De Divina Proprortione”, illustrated by Leonardo da Vinci, praised the ratio as representing divinely inspired simplicity and chaotic.
