In 1588, Tycho Brahe publishes his own Tychonic system, a blend between the Ptolemy's classical geocentric model and Copernicus' heliocentric model, in which the Sun and the Moon revolve around the Earth, in the center of universe, and all other planets revolve around the Sun. [70] It was an attempt to conciliate his religious beliefs with ...
Caldwell catalogue. Montage of Caldwell Catalogue objects. The Caldwell catalogue is an astronomical catalogue of 109 star clusters, nebulae, and galaxies for observation by amateur astronomers. The list was compiled by Patrick Moore as a complement to the Messier catalogue. [ 1]

Mayall — Nicholas Mayall (for example: globular star cluster Mayall II orbiting Messier 31, the Andromeda galaxy) Mayer (open star clusters) McC — McCormick Observatory Catalog. MCG — Morphological Catalogue of Galaxies.
In library and information science, cataloging or cataloguing is the process of creating metadata representing information resources, such as books, sound recordings, moving images, etc. Cataloging provides information such as author's names, titles, and subject terms that describe resources, typically through the creation of bibliographic records.

Two volumes of a catalogue of the remaining works were published by Erich Hermann Mueller von Asow (1892–1964) in 1959. After von Asow's death, Franz Trenner (d. 1993) and Alfons Ott (d. 1976) published the third volume, based on von Asow's notes; this catalogue lists 323 titles, including Strauss's literary writings.
Scalar field theory. In theoretical physics, scalar field theory can refer to a relativistically invariant classical or quantum theory of scalar fields. A scalar field is invariant under any Lorentz transformation. [ 1] The only fundamental scalar quantum field that has been observed in nature is the Higgs field.

1:22.6. 2. +. 1⁄2 in ( 64 mm) The smallest scale able to pull real passengers. Was one of the first popular live steam gauges, developed in England in the early 1900s. In terms of model railway operation, gauge 3 is the largest (standard gauge) scenic railway modelling scale, using a scale of 13.5 mm to the foot.
