"Why are flowers beautiful?" - This seemingly non-scientific question seems to be such only seemingly, at least for me. Are there any connections between biology and aesthethics? Between science and art? What is taste of beauty in science and not only in art? What meaning has beauty of concept or (e.g. mathematical) evaluation for resulting theory? What means such a beauty? Isn't it one of main selection criteria (apart of agreement with experiment)? Or on contrary: Isn't it its form relation to reality which makes the particular theory beautiful in our eyes? Or possibly astonishing simplification of obtained explanation of up to now complex matter make up them such? And the flowers? Are they beautiful just by considering them to be beautiful? Or are there some immanent physical properties of them, e.g., symmetry or color composition, which makes us think of them as of something beautiful? And if, what makes us think so? There is huge ammount of important theoretical research on the nature of beauty. Also great abundance of considerations on the possible relation with science in general (and not only with natural sciences, as, e.g., the below more than one hour lecture of famous physicist David Deutsch of Centre for Quantum Computation, University of Oxford). http://www.youtube.com/watch?v=gT7DFCF1Fn8 However, I think it is still worth again to be considered within our still growing RG community. That is why I am reactivating here interesting most likely for many of us thread: https://www.researchgate.net/post/Why_are_flowers_beautiful
