Speed of Light

24 Jan 2022 2 87
The speed of light could then be found by dividing the diameter of the Earth's orbit by the time difference. The Dutch scientist Christiaan Huygens, who first did the arithmetic, found a value for the speed of light equivalent to 131,000 miles per second. The correct value is 186,000 miles per second. en.wikipedia.org/wiki/Speed_of_light

www.uranos.fr/SOM_FR_04_D1.htm À la Renaissance, la cartographie céleste européenne est la même, du moins pour ce qui concerne les constellations qui sont toujours 44, comme chez Ptolémée et les astronomes arabes. Ce n’est qu'à la fin du XVIe siècle que le ciel va commencer à se modifier. During the Renaissance, the European celestial cartography is the same, at least as far as the constellations are concerned, which are always 44, as with Ptolemy and the Arab astronomers. It was not until the end of the 16th century that the sky began to change.

A Renaissance image of Aristotle: from ‘The Triumph of St. Thomas Aquinas (1471) by Benozzo Gozzoli. The book Aristotle is holding is his ‘Metaphysics’ the text, translated, reads: ‘A Sign of those who know is that they can each.’ Aristotle with Galen and Ptolemy, was taken to be the basis of all knowledge of a natural world until the Scientific Revolution, and within universities he continued to be the basis of teaching until the end of the seventeenth century. en.wikipedia.org/wiki/Triumph_of_Saint_Thomas_Aquinas_(Lipo_Memmi) Summa Theologica www.gutenberg.org/cache/epub/17611/pg17611-images.html

Waldsemuller’s world map of 1507, the first to include the name ‘America’ the first to show the New World as, in effect a new continent, and the firest to show antipodes. This map was crucial in destroying the two spheres theory and in making Copernicanism possible. At the top are the figures of Ptolemy (with a map of the Old World) and Vespucci (with the map of the New). www.loc.gov/rr/geogmap/waldexh.html en.wikipedia.org/wiki/Martin_Waldseem%C3%BCller

The oldest surviving celestial globe, made in Valencia by Ibrahim ‘Ibn Said and his son Muhammad in year 478 of the Hegira (1085 of the Christian era). Arabic astronomy was highly sophisticated, and at least the equal of any Western astronomy until Copernicus -- indeed, Copernicus may well have used technical solution devised by Arab astronomers.

Richard of Wallingford (1292-1336) constructing a mathematical instrument, probably an astrolabe. Richard of Oxford mathematician and abbot of St.Albans, made sophisticated instruments and designed an important clock. He was the closest thing the medieval world had to what we would call a scientist; however, he assumed that mathematics could be employed to interpret the heavens but not the sublunary world, and he had no notion of the experimental method. His face is spotted with what his contemporaries believed to be leprosy.
