Practical Astronomy with your Calculator is a book written by Peter Duffett-Smith, a University Lecturer and a Fellow of Downing College. It was first published in 1979 and has been in publication for over 30 years. The book teaches how to solve astronomical calculations with a pocket calculator.
Zīj as-Sindhind (Arabic: زيج السندهند الكبير, Zīj as‐Sindhind al‐kabīr, lit."Great astronomical tables of the Sindhind"; from Sanskrit siddhānta, "system" or "treatise") is a work of zij (astronomical handbook with tables used to calculate celestial positions) brought in the early 770s AD to the court of Caliph al-Mansur in Baghdad from India.
A zij (Persian: زيج, romanized: zīj) is an Islamic astronomical book that tabulates parameters used for astronomical calculations of the positions of the sun, moon, stars, and planets. Sanjufini Zij by Samarkandi astronomer Khwaja Ghazi al-Sanjufini. Compiled in 1363.
To support his plea, Banneker included within his letter a handwritten manuscript of an almanac for 1792 containing his ephemeris with his astronomical calculations. He retained handwritten copies of the letter and Jefferson's August 30, 1791, reply in a volume of manuscripts that became part of a journal.
Aristarchus's 3rd century BCE calculations on the relative sizes of, from left, the Sun, Earth and Moon, from a 10th-century CE Greek copy. On the Sizes and Distances (of the Sun and Moon) (Ancient Greek: Περὶ μεγεθῶν καὶ ἀποστημάτων [ἡλίου καὶ σελήνης], romanized: Perì megethôn kaì apostēmátōn [hēlíou kaì selḗnēs]) is widely accepted ...
Astrometric solving or Plate solving or Astrometric calibration of an astronomical image is a technique used in astronomy and applied on celestial images. Solving an image is finding match between the imaged stars and a star catalogue. The solution is a math model describing the corresponding astronomical position of each image pixel. [1]
The astronomical system of units, formerly called the IAU (1976) System of Astronomical Constants, is a system of measurement developed for use in astronomy. It was adopted by the International Astronomical Union (IAU) in 1976 via Resolution No. 1, [ 1 ] and has been significantly updated in 1994 and 2009 (see Astronomical constant ).
Trigonometry and spherical astronomy; Mean motions of the sun, moon, and planets; Planetary latitudes; Eclipses; Astrology; In modern astronomy, tables of movements of astronomical bodies are called ephemerides. These expand upon the ideas of the Toledan tables, and are used with modern computing methods to calculate where any celestial body ...
