||I have always been puzzled why the works of masters are so appealing, while the works of less skillful artists are not. I think the full explanation is in nature. For thousands of years, humans interacted only with nature, where the growth pattern of every tree and plant follows the same simple principle discovered by Fibonacci. In mathematics, the Fibonacci sequence defines the Golden Ratio, which is so fundamental and beautiful in art. Our acceptance of beauty is so fully conditioned by what we constantly see around us that anything else is not beautiful at all. Trees are the best example of this beauty.
