What is more important than science or art? In today's world, this issue is quite acute, because with the development of technology, people have ceased to consider creativity as something important. Science and art are two fields of activity that accompany the development of mankind throughout its existence. For science to benefit people, it must be closely linked to art. Both the scientist and the artist recreate the world in the name of the main goal - the comprehension of truth, beauty and goodness. People of science and art are United by thoughts and creativity. Music, painting, sculpture develop in us a sense of beauty, aesthetic taste, and thanks to the development of science there are necessary things such as the Internet, drugs for cancer and AIDS. However, science and art solve different problems : the first studies objective laws, and the second - the attitude of man to the world, to other people, to himself. Art helps to Express your feelings and emotions in your work, which is very important for a person, because we are not robots. Answering the question posed at the beginning, I can say that the truth is in the middle. Physics is not more important than the painting, but the quality is not more important than, for example, music. My life is also closely connected with both, as I have been engaged in drawing for a long time and now I am studying in Rosneft class, where there is a deep study of physics and mathematics. So I don't think that something this important samostalno.
