4:42 New evidence. Remember Pythagoras? Mathematician, cult leader. Athens, circa 500 BC. Major belief: The universe is made of numbers. Major contribution: The golden ratio. Best represented geometrically as the golden rectangle. Visually, there exists a graceful equilibrium between the shapes length and width. When it's squared, it leaves a smaller golden rectangle behind, with the same unique ratio. The squaring can continue, smaller and smaller and smaller, to infinity.
11:18. More evidence. Remember da Vinci? Artist, inventor, sculptor, naturalist. ltaly, 15th century. Rediscovered the balance of perfection of the golden rectangle and penciled it into his masterpieces. Connecting a curve through the concentric golden rectangles, You generate the mythical golden spiral. Pythagoras loved this shape, for he found it everywhere in nature - a nautilus shell, rams' horns, whirlpools, tornadoes, our fingerprints, our DNA and even our Milky Way.
9:22. Personal note. When I was a little kid, my mother told me not to stare into the sun. So once when I was 6, I did. At first, the brightness was overwhelming, but I kept looking, forcing myself not to blink. And then the brightness began to dissolve. My pupils shrank to pinholes and everything came into focus. And for a moment I understood. My new hypothesis: if we're built from spirals, while living in a giant spiral, then everything put our hands to is infused with the spiral.
