Interview with Steven Weinberg, American theoretical physicist (in his office at the University of Texas in Austin, Texas). Weinberg talks about the demythologization of the world and the consolation for this loss that can be found in the beauty of physical theories. He compares the beauty of the laws of physics (including Albert Einstein's theory of relativity) with perfection in artistic expressions such as the music of Johann Sebastian Bach. Attention is also paid to symmetrical principles, the insoluble question "why?" and the current trend to make something magical out of science. Weinberg explains why he disapproves of this trend. Weinberg's opinion that religion is a myth that will disappear is also discussed.
