Science deals with facts while the art is imaginary. The real thing that exists is a science. Art is something abstract.
Art can be behavioral while the science is intellectual. Never confuse these two.
They are different. But both are important in their own way. The combination of both is necessary for innovation. Let’s take an example of Apple. The I-phone is based on technology and has several tech features which is science, but its design is an art that has made it unique among others in the market.
