Deutsche Physik (literally: "German Physics") or Aryan Physics was a nationalist movement in the German physics community in the early 1930s against the work of Albert Einstein and other modern theoretically based physics, labeled "Jewish Physics" (German: Jüdische Physik). The term was taken from the title of a 4-volume physics textbook by Philipp Lenard in the 1930s.
