Giovanni Bianchini
Giovanni Bianchini (in Latin, Johannes Blanchinus) (1410 – c. 1469) was a professor of mathematics and astronomy at the University of Ferrara and court astrologer of Leonello d'Este. He was an associate of Georg Purbach and Regiomontanus. The letters exchanged with Regiomontanus in 1463–1464 mention works by Bianchini entitled: ''Primum mobile'' ( astronomical tables included), ''Flores almagesti'', ''Compositio instrumenti''. Bianchini was the first mathematician in Europe to use decimal positional fractions for his trigonometric tables, at the same time as Al-Kashi in Samarkand. In ''De arithmetica'', part of the ''Flores almagesti'', he uses operations with negative numbers and expresses the ''Law of Signs''. He was probably the father of the instrument maker Antonio Bianchino. The crater Blanchinus on the Moon is named after him.

15th-century Italian Mathematicians
The 15th century was the century which spans the Julian dates from 1 January 1401 ( MCDI) to 31 December 1500 ( MD). In Europe, the 15th century includes parts of the Late Middle Ages, the Early Renaissance, and the early modern period. Many technological, social and cultural developments of the 15th century can in retrospect be seen as heralding the "European miracle" of the following centuries. The architectural perspective, and the modern fields which are known today as banking and accounting were founded in Italy. The Hundred Years' War ended with a decisive French victory over the English in the Battle of Castillon. Financial troubles in England following the conflict resulted in the Wars of the Roses, a series of dynastic wars for the throne of England. The conflicts ended with the defeat of Richard III by Henry VII at the Battle of Bosworth Field, establishing the Tudor dynasty in the later part of the century. Constantinople, known as the capital of the world an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Dizionario Biografico Degli Italiani
The ''Dizionario Biografico degli Italiani'' ( en, Biographical Dictionary of the Italians) is a biographical dictionary published by the Istituto dell'Enciclopedia Italiana, started in 1925 and completed in 2020. It includes about 40,000 biographies of distinguished Italians. The entries are signed by their authors and provide a rich bibliography. History The work was conceived in 1925, to follow the model of similar works such as the German ''Allgemeine Deutsche Biographie'' (1912, 56 volumes) or the British '' Dictionary of National Biography'' (from 2004 the ''Oxford Dictionary of National Biography''; 60 volumes). It is planned to include biographical entries on Italians who deserve to be preserved in history and who lived at any time during the long period from the fall of the Western Roman Empire to the present. As director of the Treccani, Giovanni Gentile entrusted the task of coordinating the work of drafting to Fortunato Pintor, who was soon joined by Arsenio Frugoni ...

Blancanus (crater)
Blancanus is a lunar impact crater located in the rugged southern region of the Moon, to the southwest of the walled plain Clavius. To the northwest lies the comparably sized crater Scheiner, and south-southwest of Blancanus is the worn Klaproth. The outer rim of Blancanus is considerably less worn than that of Scheiner crater to the northwest, and the edge is still fairly well defined and it has a terraced structure on the interior. The floor is relatively flat with several low rises at the midpoint. There is a cluster of small craterlets in the southern part of the crater floor. Crater Blancanus is named after the Jesuit astronomer and natural philosopher, Giuseppe Biancani Giuseppe Biancani, SJ (Latin: Josephus Blancanus) (1566–1624) was an Italian Jesuit astronomer, mathematician, and selenographer, after whom the crater Blancanus on the Moon is named.

Giuseppe Biancani
Giuseppe Biancani, SJ (Latin: Josephus Blancanus) (1566–1624) was an Italian Jesuit astronomer, mathematician, and selenographer, after whom the crater Blancanus on the Moon is named. He was a native of Bologna. Works His ''Aristotelis loca mathematica ex universis ipsius operibus collecta et explicata'', published in Bologna, appeared in 1615, in which Biancani discussed Aristotelian thought on floating bodies. The work suffered censorship whilst undergoing peer review, a common Jesuit practice. The reviewer, Giovanni Camerota, wrote: "It does not seem to be either proper or useful for the books of our members to contain the ideas of Galileo Galilei, especially when they are contrary to Aristotle." Biancani wrote his ''Sphaera mundi, seu cosmographia demonstrativa, ac facili methodo tradita'' in 1615. However, it was not published until 1619 in Bologna, after the Decree of the Congregation of the Index in 1616. In his ''Sphaera mundi'', Biancani expounded on his be ...

Bianchini (crater)
Bianchini is a lunar impact crater that lies along the northern Jura Mountains that ring the Sinus Iridum, in the northwestern part of the near side of the Moon. It was named after Italian astronomer Francesco Bianchini Francesco Bianchini (13 December 16622 March 1729) was an Italian philosopher and scientist. He worked for the curia of three popes, including being ''camiere d'honore'' of Clement XI, and secretary of the commission for the reform of the cal .... The impact of this crater near the edge of the Jura Mountains deposited some material into the Sinus Iridum floor. The rim of this crater is not significantly worn, although there is a small crater along the inner side of the eastern rim. Within the inner wall is a somewhat irregular floor and a small cluster of ridges at the midpoint. Portions of the inner wall have slumped toward the floor along the northern edges. Satellite craters By convention these features are identified on lunar maps by placing the letter ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Francesco Bianchini
Francesco Bianchini (13 December 16622 March 1729) was an Italian philosopher and scientist. He worked for the curia of three popes, including being ''camiere d'honore'' of Clement XI, and secretary of the commission for the reform of the calendar, working on the method to calculate the astronomically correct date for Easter in a given year. Life and work Bianchini was born of a noble family at Verona, the son of Giuseppe Bianchini and his wife, Cornelia Vailetti. Educated by Jesuits in Bologna, and by the Paduan astronomer, Geminiano Montanari, Bianchini spent most of his university years in Padua studying comets while enrolled in Theology. This early training in astronomy established Bianchini's commitment to the experimental and physical sciences. In 1684 he went to Rome, and became librarian to Cardinal Ottoboni, who, as Pope Alexander VIII (1689), raised him to the offices of papal chamberlain and canon of Santa Maria Maggiore. Clement XI sent him on a mission to Paris in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Moon
The Moon is Earth's only natural satellite. It is the fifth largest satellite in the Solar System and the largest and most massive relative to its parent planet, with a diameter about one-quarter that of Earth (comparable to the width of Australia). The Moon is a planetary-mass object with a differentiated rocky body, making it a satellite planet under the geophysical definitions of the term and larger than all known dwarf planets of the Solar System. It lacks any significant atmosphere, hydrosphere, or magnetic field. Its surface gravity is about one-sixth of Earth's at , with Jupiter's moon Io being the only satellite in the Solar System known to have a higher surface gravity and density. The Moon orbits Earth at an average distance of , or about 30 times Earth's diameter. Its gravitational influence is the main driver of Earth's tides and very slowly lengthens Earth's day. The Moon's orbit around Earth has a sidereal period of 27.3 days. During each synodic period ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Blanchinus (crater)
Blanchinus is a lunar impact crater that is situated in the rugged south-central highlands of the Moon. The crater is named after Italian astronomer Giovanni Bianchini whose Latinized name is Blanchinus. Adjacent to the south of Blanchinus is the crater Werner, and La Caille Abbé Nicolas-Louis de Lacaille (; 15 March 171321 March 1762), formerly sometimes spelled de la Caille, was a French astronomer and geodesist who named 14 out of the 88 constellations. From 1750 to 1754, he studied the sky at the Cape of Goo ... is attached to the northwest rim. West of the crater is the prominent formation Purbach. The outer rim of Blanchinus has been significantly degraded by subsequent impacts, leaving an irregular, notched exterior ring of rugged hills and ridges. The inner floor, in contrast, is nearly flat and free of significant impacts. Only a few tiny craterlets mark the interior surface, with Blanchinus M located near the midpoint and the remainder lie near the southwest rim ...
