Mayan astronomers The Mayan culture, began after the Olmec civilization, located in Central America about 500 B.C. They tied many of their beliefs and traditions to the celestial heavens. Ancient Mayan astronomers used mathematical accuracy when setting calendars and predicting orbits of planets.plato discover Plato (born 428/427 bce, Athens, Greece—died 348/347, Athens) was an ancient Greek philosopher, student of Socrates (c. 470–399 bce), teacher of Aristotle (384–322 bce), and founder of the Academy. He is best known as the author of philosophical works of unparalleled influence and is one of the major figures of Classical antiquity.Aristarchus of Samos Aristarchus of Samos (born c. 310 bce—died c. 230 bce) was a Greek astronomer who maintained that Earth rotates on its axis and revolves around the Sun. On this ground, the Greek philosopher Cleanthes the Stoic declared in his Against Aristarchus that Aristarchus ought to be indicted for impiety “for putting into motion the hearth of the universe.”Claudius Ptolemy 170 ce) was an Egyptian astronomer, mathematician, and geographer of Greek descent who flourished in Alexandria during the 2nd century ce. In several fields his writings represent the culminating achievement of Greco-Roman science, particularly his geocentric (Earth-centred) model of the universe now known as the Ptolemaic system.Muhammad ibn Musa al-Khwarizmi Muhammad ibn Musa al-Khwarizmi[note 1] (Persian: محمد بن موسى خوارزمی; c. 780 – c. 850), or simply al-Khwarizmi, was a polymath who produced vastly influential Arabic-language works in mathematics, astronomy, and geography. Around 820, he worked at the House of Wisdom in Baghdad, the contemporary capital city of the Abbasid Caliphate.
His popularizing treatise on algebra, compiled between 813 and 833 as Al-Jabr (The Compendious Book on Calculation by Completion and Balancing)Copernicus Nicolaus Copernicus[b] (19 February 1473 – 24 May 1543) was a Renaissance polymath who formulated a model of the universe that placed the Sun rather than Earth at its center. Copernicus likely developed his model independently of Aristarchus of Samos, an ancient Greek astronomer who had formulated such a model some eighteen centuries earlier.[6][c][d][e]
The publication of Copernicus' model in his book De revolutionibus orbium coelestium (On the Revolutions of the Celestial Spheres), just beforeGalileo Galilei Galileo di Vincenzo Bonaiuti de' Galilei (15 February 1564 – 8 January 1642), commonly referred to as Galileo Galilei (/ˌɡælɪˈleɪoʊ ˌɡælɪˈleɪ/, US also /ˌɡælɪˈliːoʊ -/; Italian: [ɡaliˈlɛːo ɡaliˈlɛːi]) or mononymously as Galileo, was an Italian[a] astronomer, physicist and engineer, sometimes described as a polymath. He was born in the city of Pisa, then part of the Duchy of Florence.[8] Galileo has been called the father of observational astronomy,[9] modern-era classical physics,[10] the scIsaac Newton Although it was claimed that he was once engaged,[b] Newton never married. The French writer and philosopher Voltaire, who was in London at the time of Newton's funeral, said that he "was never sensible to any passion, was not subject to the common frailties of mankind, nor had any commerce with women—a circumstance which was assured me by the physician and surgeon who attended him in his last moments.”[152] There exists a widespread belief that Newton died a virgin, with some writers such as mJohann Gottfried Galle Johann Gottfried Galle (9 June 1812 – 10 July 1910) was a German astronomer from Radis, Germany, at the Berlin Observatory who, on 23 September 1846, with the assistance of student Heinrich Louis d'Arrest, was the first person to view the planet Neptune and know what he was looking at. Urbain Le Verrier had predicted the existence and position of Neptune, and sent the coordinates to Galle, asking him to verify.[1] Galle found Neptune in the same night he received Le Verrier's letter, Edwin Hubble dwin Powell Hubble (November 20, 1889 – September 28, 1953)[1] was an American astronomer. He played a crucial role in establishing the fields of extragalactic astronomy and observational cosmology.[2][3]
Hubble proved that many objects previously thought to be clouds of dust and gas and classified as "nebulae" were actually galaxies beyond the Milky Way.[4] He used the strong direct relationship between a classical Cepheid variable's luminosity and pulsation period[5][6] (discovered in 1908 bApollo 11 Apollo 11 was a spaceflight conducted from July 16 to 24, 1969, by the United States and launched by NASA. It marked the first time that humans landed on the Moon. Commander Neil Armstrong and Lunar Module Pilot Buzz Aldrin landed the Apollo Lunar Module Eagle on July 20, 1969, at 20:17 UTC, and Armstrong became the first person to step onto the Moon's surface six hours and 39 minutes later, on July 21 at 02:56 UTC. Aldrin joined him 19 minutes later, and they spent about two and a quarter hours tKatie Bouman Katherine Louise Bouman (/ˈbaʊmən/;[1] born 1989) is an American engineer and computer scientist working in the field of computational imaging. She led the development of an algorithm for imaging black holes, known as Continuous High-resolution Image Reconstruction using Patch priors (CHIRP), and was a member of the Event Horizon Telescope team that captured the first image of a black hole.[2][3][4]
