When looked at from the front, the shape of the Parthenon appears to resemble a golden rectangle. This is interesting as construction of it had completed in 438 B.C.E but it wasn’t documented by the Greeks until 300 B.C.E. Many theories for this include that, as it is present in nature, the golden ratio is aesthatically pleasing to the human eye.
As seen above, the Taj Mahal, built in 1648 by Ustad Ahmad Lahore for Mughal Emperor Shahjahan and his wife, is also known to form a golden rectangle from a frontal view
A more modern example of the golden ratio in architecture, the UN Building has 4 levels with clear glass, forming 3 golden rectangles.
Pinecones display many golden spirals from the centre of seed outwards.
It is surprising, personally, to see that the golden ratio is present in inanimate, abiotic objects. The Milky Way, our home galaxy, has several golden spirals extending from the centre.
Even at a miniscule level, the golden ratio is known to exist. Each DNA molecule measures 34 angstroms long by 21 angstroms wide and as learnt in class, the higher the consecutive fibonacci numbers are, the closer and closer the ratio of these 2 numbers gets to phi.
