Golden Ratios

John picked up the tiny shell. He quickly dipped it into the tidal pool next to him, washing away the sand. It glistened and sparkled with a myriad of vibrant rainbow colours in the summer sun.

Placing it in the middle of his palm, he showed it to his daughter.

"Why does it go round dad?"

"It's called the golden ratio. This little shell reflects our Universe." He pointed at the middle. "This is where it starts. Tiny. Then it grows, and grows, until it's big enough for everything we know. Big enough to see in the tiniest of shells."
