Example: In one work this author details the life of a tomb-maker who makes extra money by playing the organ at an insane asylum, while another of his novels sees Swartz give a refugee proper documentation only after he tells him his life story in the title Portuguese city. In addition to The Black Obelisk and The Night in Lisbon, he also wrote about Robert and Otto selling their auto workshop and visiting Patrice in a Swiss tuberculosis sanatorium in his novel The Three Comrades, while the turbulent life of the German surgeon Ravic is told in The Arch of Triumph. Another of his novels, The Road Back, is thought to be a sequel to his most famous book, in which the patriotic teacher Kantorek convinces Paul Bumer and his friends to join the Germany Army during World War I. For 10 points, name this German author who wrote All Quiet on the Western Front.
Output: Literature
The text is talking about an author and their works, so it belongs to theliterature category.

New input case for you: Pneuman and Kopp provided the first ab initio model of this phenomenon by integrating the MHD equation for a dipole source; their model closely matched Parkers 1956 model. Evidence for this object was provided by Biermanns observations of comets, though it was not observed until Luna 1. Its interaction with the terrestrial magnetic field results in the bow shock. It ceases being supersonic at the termination shock and its velocity falls to zero at the heliopause, where it merges with the interstellar medium. Radiation pressure and pressure from this plasma flow cause comet tails to always face away from the center of the solar system. For 10 points, name this stream of particles constantly emanating from the sun.
Output:
Science
