When analyzing both modern and ancient architecture, it is easy to find the Golden Ratio, the Golden Triangle, and Fibonacci numbers in architecture. Starting with the Parthenon in Ancient Greece, the Golden Ratio can be observed in architecture in order to create some of the most beautiful buildings in history.
The Golden Spiral, which can be found through using the Fibonacci numbers and the Golden Ratio, can also be found in modern spiral staircases as well as breathtaking buildings such as the British National Wildflower Center. Great Mosque of Kairouan in Tunisia uses the Golden Ratio, as do the Lotfollah Mosque and Naqsh-e Jahan Square in Iran.
More than just being able to find Fibonacci numbers in architecture, they can also be found in nature, art, and music as well. In nature, they explain the placement of leaves on the stem of a plant and the shape of a shell. In art, they have been used for some of the most beautiful art in the world, including the Mona Lisa. And in music, Fibonacci numbers were used in the music of Mozart as well as progressive rock band, Tool.
The use of Fibonacci numbers in architecture, art, and music helps to incorporate the Golden Ratio into our everyday lives, making the world a more beautiful place for us all.
