The Golden Ratio in Nature
The Golden Ratio manifests itself in many places across the universe,
including Earth’s nature and even to our human body parts.
1. Flower petals. The number of flower petals is
often one of the following numbers: 3, 5, 8, 13, 21, 34

buttercups have five of them, the chicory has 21 of
them, the daisy has often 34 or 55 petals, etc.

3. Body parts. The Golden Section is
manifested in the structure of the human body.
Your hand creates a golden section in relation to
your arm, as the ratio of your forearm to your hand

several proportions based on phi lines, including:
