We feel pleasure and we call it beauty.”īut what has all this got to do with PowerPoint grids and guides? Writing about the golden ratio he said: “Shapes that resemble the golden ratio facilitate the scanning of images and their transmission through vision organs to the brain…When we see the proportions in the golden ratio, we are helped. He believes cognition and vision have evolved together in a way that increases the efficiency of information flowing from the world into our brains. Professor of mechanical engineering Adrian Bejan argued that our brains find objects that fit the golden ratio beautiful because our eyes can interpret them faster. Though people are still debating why the golden ratio is so visually pleasing, most assume that it’s because it seems to appear everywhere – from the arms of galaxies to the spirals of shells to this photograph of typical New Year’s Eve celebrations in the UK. See how Mona Lisa’ s mysterious face lines up with the golden spiral: Famed polymath Leonardo da Vinci incorporated the mathematics of this ratio into his paintings. Based on the golden ratio, the golden spiral can be found in some of the most famous artworks in the world.
Why are grids important?įans of Renaissance art and/or geometry – I know you’re out there! – might have heard of the golden spiral. However, help is at hand!
