Azathoth is a deity in the Cthulhu Mythos and Dream Cycle stories of writer H. P. Lovecraft and other authors. He is the supreme deity of the Cthulhu Mythos and the ruler of the Outer Gods, [1] and may also be seen as a symbol for primordial chaos, [2] therefore being the most powerful entity in the entirety of the Cthulhu Mythos.
This cover of I, Robot illustrates the story "Runaround", the first to list all Three Laws of Robotics.. The Three Laws of Robotics (often shortened to The Three Laws or Asimov's Laws) are a set of rules devised by science fiction author Isaac Asimov, which were to be followed by robots in several of his stories.
Isaac Asimov (/ ˈ æ z ɪ m ɒ v / AZ-im-ov; [b] [c] c. January 2, 1920 [a] – April 6, 1992) was an American writer and professor of biochemistry at Boston University.During his lifetime, Asimov was considered one of the "Big Three" science fiction writers, along with Robert A. Heinlein and Arthur C. Clarke. [2]
"Azathoth" is the beginning of an incomplete novel written by American horror fiction writer H. P. Lovecraft. [1] It was written in June 1922, and published as a fragment in the journal Leaves in 1938, after Lovecraft's death. [2]
The azimuth is the angle formed between a reference direction (in this example north) and a line from the observer to a point of interest projected on the same plane as the reference direction orthogonal to the zenith.
The physics convention.Spherical coordinates (r, θ, φ) as commonly used: (ISO 80000-2:2019): radial distance r (slant distance to origin), polar angle θ (angle with respect to positive polar axis), and azimuthal angle φ (angle of rotation from the initial meridian plane).
Authors other than Asimov have often created extra laws. The 1974 Lyuben Dilov novel, Icarus's Way (a.k.a., The Trip of Icarus) introduced a Fourth Law of robotics: "A robot must establish its identity as a robot in all cases."
Horizontal coordinates use a celestial sphere centered on the observer. Azimuth is measured eastward from the north point (sometimes from the south point) of the horizon; altitude is the angle above the horizon.
