Lopo Ekeroth Simoes Posted over 2 years ago Why are man-made creations so symmetrical? In nature symmetries exist in systems with lots of energy, so we are hardwired to take interest in them. Symmetrical systems have very low entropy, which implies a considerable amount of stored energy. what we call beauty or balance is just the rhetoric the nervous system has created to help us deal with these complex systems. In terms of man made design, putting aside all the cases where symmetry is necessary for function, symmetry is simply used as a way to get our brain to pay attention.
