Non-Euclidean geometry caused a re-examination of the teaching of geometry based on Euclid's Elements. This curriculum issue was hotly debated at the time and was even the subject of a book, "Euclid and his Modern Rivals", written by Charles Lutwidge Dodgson (1832–1898) better known as Lewis Carroll, the author of "Alice in Wonderland". In analytic geometry a plane is described with Cartesian coordinates : "C" = { ("x,y") : "x", "y" ∈ ℝ }. The points are sometimes identified with complex numbers where ε ∈ { –1, 0, 1}. The Euclidean plane corresponds to the case since the modulus of is given

By failing to mention traditional Jewish interpretations of this verse that define dominion as responsible stewardship rather than as domination, he may leave the mistaken impression that the exploitation of animals and the environment is religiously sanctioned.” Charles Patterson's "Eternal Treblinka" discusses the similarities between society's treatment of animals and the Holocaust.
