When I think about these two concepts, to my mind comes such brilliant artist as Michelangelo Buonarroti and Leonardo da Vinci. They fully understood the unique combination of art and science and how important it was to think innovatively. Renaissance is the period when science and art began to live together. That's why we shouldn't ask ourselves is design a science or an art; because design is a combination of art and science in the most inspirational and creative ways in order to keep innovation flowing.
Science helps us create a lot of beautiful things, pieces of art as well as all of the tools and things that fulfill our aesthetic needs. The best creations and innovations, though, are those that combine those functions with a form that is pleasing to the eye as well as the hand.
