The document discusses several 20th century abstract art movements that emerged from intellectual ideas in science. Abstractionism analyzed and simplified subjects rather than representing the natural world. Key movements discussed include Cubism, in which Picasso broke subjects into geometric planes; Futurism, inspired by machinery's motion; Mechanical style using industrial forms and primary colors; and Nonobjectivism using only lines, shapes and black/white without recognizable objects. These abstract styles paved the way for other contemporary art.
