The document summarizes major cultural and scientific developments during the early 20th century. Albert Einstein introduced his theory of relativity, which established that time and space are relative to the observer's movement and speed. Sigmund Freud founded psychoanalysis and emphasized the unconscious mind and dream interpretation. Artistic movements like expressionism, surrealism, and cubism revolutionized painting, while jazz emerged as a new American musical style. Women's roles also changed after World War 1 as society became more liberal.
