What is the most beautiful number? It is, of course, phi. Also known as the golden ratio, it is represented by the Greek symbol φ , and is the most irrational of irrational numbers. φ can also be written as this:
(1+sqrt5)/2. This may look ugly, but it is it. φ is used everywhere, in buildings and artworks and even the Milky Way galaxy relates to it. φ isn’t just about buildings and artwork, but it is related to the Fibonacci sequence.
Here is a question: what starts with 1 1 2 3 5 8 13 21 34 55 89? It is, of course, the Fibonacci sequence. The spiral is also interesting, where you put two 1×1 squares together and put a square with dimensions 2×2 then 3×3 then 5×5 …
φ can also be represented as this ugly little thing:
φ = 1+1/ φ = 1+1/( 1+1/( 1+1/( 1+1/( 1+1/( 1+1/( 1+1/( 1+1/( 1+1/( 1+1/( 1+1/( 1+1/( 1+1/( 1+1/( 1+1/( 1+1/( 1+1/( 1+1/( 1+1/( 1+1/( 1+1/( 1+1/( 1+1/( 1+1/( 1+1/( 1+1/( 1+1/( 1+1/( 1+1/( 1+1/( 1+1/( 1+1/( 1+1/( 1+1/( 1+1/( … and you’d never be able to get to the end!
This was Part 1. Get ready for Part 2. I GuaRanTEe that it will be awesome and awesome! SeE you.
