Art And Science
Art and science co-exist with each other. The former might be older than the latter but both phenomena influence each other in one way or another.
Art would refer to something that is related to beauty or just anything the optical sense is fascinated with. Art is in the eye of the beholder. It is technically the same thing with beauty.
City of Arts & Sciences
Science, just like art, also incorporates different disciplines but in the broad description, science is the art of discovering.
Both are attached to each other. The thing is art appeals to humanities while science is rooted with advancement and modernisation.
