### Everything you Need to Know About The Golden Ratio #infographic

When you hear the words "golden ratio," you may remember something about a spiral or some guy named Fibonacci. You might also recall a specific number from geometry class—1:1.618. The golden ratio is based on a sequence of numbers that Fibonacci discovered. As the numbers in the sequence increase, the ratio between two adjacent numbers gets closer to—you guessed it—1:1.618. Not only does this ratio occur in a sequence of numbers, it's prevalent in the natural world, too. Many people believe…
