The development of Indian trigonometry , based on sine as against chord of the Greeks , a necessity for astronomical calculations with his own concise notation which expresses the full sine table in just one couplet for easy remembrance. One of the two methods suggested by him for the sine table is based on the property that the second order sine differences were proportional to sines themselves.
Either Stone Age man was a technological wizard, who carefully removed his technological achievements so as not to upset his inferior progeny, or our population dwindled from a once astronomical size to the mere three billions of today.heinz von foerster
Wisdom is not mathematical, nor astronomical, nor zoological; when it talks too much of any one thing it ceases to be itself. There are wise physicists, but wisdom is not physical; there are wise physicians, but wisdom is not medical.george sarton
Whatever the Thinker thinks, the Prover will prove. And if the Thinker thinks passionately enough, the Prover will prove the thought so conclusively that you will never talk a person out of such a belief, even if it is something as remarkable as the notion that there is a gaseous vertebrate of astronomical heft (" GOD ") who will spend all eternity torturing people who do not believe in his religion.robert anton wilson
Jaisingh collected and studied all the available astronomical works...Several European works were translated into Sanskrit under his orders, particularly Euclid ’s elements, with a treatise on plane and spherical trigonometry ; and on the construction and use of logarithms ...and also a treatise on conical sections...maps and globes of the Ferenghis were obtained from Surat .
Theologians are delighted that the astronomical evidence leads to a biblical view of Genesis but curiously, astronomers are upset.
We are, by astronomical standards, a pampered, cosseted, cherished group of creatures. ... If the Universe had not been made with the most exacting precision we could never have come into existence. It is my view that these circumstances indicate the universe was created for man to live in.
The credit of first using the telescope for astronomical purposes is almost invariably attributed to Galilei, though his first observations were in all probability slightly later in date than those of Harriot and Marius , is to a great extent justified by the persistent way in which he examined object after object, whenever there seemed any reasonable prospect of results following, by the energy and acuteness with which he followed up each clue, by the independence of mind with which he interpreted his observations, and above all by the insight with which he realised their astronomical importance.
His fame rests mainly on his Aryabhatiya, but from the writings of Varahamihira (Sixth century AD), Bhaskara I, and Brahmagupta (seventh century) it is clear that earlier he composed the Aryabhata Siddhantha (voluminous) is not extant. It is also called Ardharatrika Siddhanta , because in it the civil days were reckoned from one midnight to the next; 34 verses on astronomical instruments from this have been quoted by Ramakrishna Aradya.
The sexagesimal system was used also in fractions. Thus, in the Babylonian inscriptions, 1/2 and 1/3 are designated by 30 and 20, the reader being expected, in his mind, to supply the word "sixtieths." The Greek geometer Hypsicles and the Alexandrian astronomer Ptolemæus borrowed the sexagesimal notation of fractions from the Babylonians and introduced it into Greece. From that time sexagesimal fractions held almost full sway in astronomical and mathematical calculations until the sixteenth century, when they finally yielded their place to the decimal fractions.
Just as the line of astronomical thinkers from Copernicus to Newton had destroyed the old astronomy, in which the earth was the center, and the Almighty sitting above the firmament the agent in moving the heavenly bodies about it with his own hands, so now a race of biological thinkers had destroyed the old idea of a Creator minutely contriving and fashioning all animals to suit the needs and purposes of man.Andrew Dickson White
The human race, whose intelligence dates back only a single tick of the astronomical clock, could hardly hope to understand so soon what it all means.james jeans
By means of microscopic observation and astronomical projection the lotus flower can become the foundation for an entire theory of the universe and an agent whereby we may perceive the Truth. And first we must know that each of the petals has eighty-four thousand veins and that each vein gives eighty-four thousand lights.yukio mishima
