I think that abstract artists are mathematicians and scientists at heart because artists do the same thing that mathematicians and scientists do. Out of the universal set of all things that exist artists, mathematicians and scientists extract subsets of reality and combine them in different ways. All of math and science can be described with sets. So can art. Sets of different patterns and colours intersecting to create something new. That is how nature is constructed. Abstract art creates something new. Abstract art is a result of the process of creation. Part of that creation is the response that the art creates in the viewer. Some creation produces a bad response, some indifferent, some no response and some a captivating response. The art draws the viewer to it like a magnet. Magnetism is a very powerful unseen force. What captivates me the most is how artists use light and shading. Some artists create light that I have never seen before. It is captivating especially in a context where my mind creates new images out of the set of patterns and shapes that the artist lays down on canvas. So I would say that great abstract art is art that provides a medium for the viewer to create their own art out of the artists work. By that standard Monika's art is brilliant.
