Guido Ubaldi
Guidobaldo del Monte (11 January 1545 – 6 January 1607, var. Guidobaldi or Guido Baldi), Marquis del Monte, was an Italian mathematician, philosopher and astronomer of the 16th century. Biography Del Monte was born in Pesaro. His father, Ranieri, was from a leading wealthy family in Urbino. Ranieri was noted for his role as a soldier and also as the author of two books on military architecture. The Duke of Urbino, Duke Guidobaldo II, honoured him with the title Marchese del Monte so the family had only become a noble one in the generation before Guidobaldo. On the death of his father Guidobaldo inherited the title of Marchese. Guidobaldo studied mathematics at the University of Padua in 1564. While there he became a friend of the great Italian poet Torquato Tasso. In fact Guidobaldo may have known Tasso before they studied at Padua together, for Tasso was almost exactly the same age as Guidobaldo and had been educated at the court of the Duke of Urbino, with the duke's so ...

Marche
Marche ( , ) is one of the twenty regions of Italy. In English, the region is sometimes referred to as The Marches ( ). The region is located in the central area of the country, bordered by Emilia-Romagna and the republic of San Marino to the north, Tuscany to the west, Umbria to the southwest, Abruzzo and Lazio to the south and the Adriatic Sea to the east. Except for river valleys and the often very narrow coastal strip, the land is hilly. A railway from Bologna to Brindisi, built in the 19th century, runs along the coast of the entire territory. Inland, the mountainous nature of the region, even today, allows relatively little travel north and south, except by twisting roads over the passes. Urbino, one of the major cities of the region, was the birthplace of Raphael, as well as a major centre of Renaissance history. Toponymy The name of the region derives from the plural of the medieval word '' marca'', meaning "march" or "mark" in the sense of border zone, originall ...

Francesco Maria Del Monte
Francesco Maria del Monte, full name Francesco Maria Bourbon del Monte Santa Maria, (5 July 1549 – 27 August 1627) was an Italian Cardinal, diplomat, and connoisseur of the arts. His fame today rests on his early patronage of the important Baroque master Caravaggio, and on his art collection (the del Monte collection) which provides provenance for many important works of the period. Career Born in Venice of the aristocratic del Monte family of Tuscan origin (which provided several cardinals to the Church), he was the son of Marquis Ranieri Bourbon del Monte, first Count of Monte Baroccio, and Minerva Pianosa. He began his ecclesiastical career as Abbot commendatario of Santa Croce a Monte Fabali. He then went to Rome when he was still quite young, and was appointed as auditor for Cardinal Alessandro Sforza, before being finally admitted into the court of Cardinal Ferdinando de' Medici. He made his way up through the clerical ranks as Referendary of the Tribunals of the Aposto ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hydrostatic Balance
In fluid mechanics, hydrostatic equilibrium (hydrostatic balance, hydrostasy) is the condition of a fluid or plastic solid at rest, which occurs when external forces, such as gravity, are balanced by a pressure-gradient force. In the planetary physics of Earth, the pressure-gradient force prevents gravity from collapsing the planetary atmosphere into a thin, dense shell, whereas gravity prevents the pressure-gradient force from diffusing the atmosphere into outer space. Hydrostatic equilibrium is the distinguishing criterion between dwarf planets and small solar system bodies, and features in astrophysics and planetary geology. Said qualification of equilibrium indicates that the shape of the object is symmetrically ellipsoid, where any irregular surface features are consequent to a relatively thin solid crust. In addition to the Sun, there are a dozen or so equilibrium objects confirmed to exist in the Solar System. Mathematical consideration For a hydrostatic fluid on Ear ...

Compass
A compass is a device that shows the cardinal directions used for navigation and geographic orientation. It commonly consists of a magnetized needle or other element, such as a compass card or compass rose, which can pivot to align itself with magnetic north. Other methods may be used, including gyroscopes, magnetometers, and GPS receivers. Compasses often show angles in degrees: north corresponds to 0°, and the angles increase clockwise, so east is 90°, south is 180°, and west is 270°. These numbers allow the compass to show azimuths or bearings which are commonly stated in degrees. If local variation between magnetic north and true north is known, then direction of magnetic north also gives direction of true north. Among the Four Great Inventions, the magnetic compass was first invented as a device for divination as early as the Chinese Han Dynasty (since c. 206 BC),Li Shu-hua, p. 176 and later adopted for navigation by the Song Dynasty Chinese during the 11th centur ...

Polygon
In geometry, a polygon () is a plane figure that is described by a finite number of straight line segments connected to form a closed ''polygonal chain'' (or ''polygonal circuit''). The bounded plane region, the bounding circuit, or the two together, may be called a polygon. The segments of a polygonal circuit are called its '' edges'' or ''sides''. The points where two edges meet are the polygon's '' vertices'' (singular: vertex) or ''corners''. The interior of a solid polygon is sometimes called its ''body''. An ''n''-gon is a polygon with ''n'' sides; for example, a triangle is a 3-gon. A simple polygon is one which does not intersect itself. Mathematicians are often concerned only with the bounding polygonal chains of simple polygons and they often define a polygon accordingly. A polygonal boundary may be allowed to cross over itself, creating star polygons and other self-intersecting polygons. A polygon is a 2-dimensional example of the more general polytope in any number ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Technical Drawing
Technical drawing, drafting or drawing, is the act and Academic discipline, discipline of composing Plan (drawing), drawings that Visual communication, visually communicate how something functions or is constructed. Technical drawing is essential for communicating ideas in Manufacturing, industry and engineering. To make the drawings easier to understand, people use familiar symbols, Perspective (graphical), perspectives, units of measurement, notation systems, visual styles, and page layout. Together, such Convention (norm), conventions constitute a visual language and help to ensure that the drawing is unambiguous and relatively easy to understand. Many of the symbols and principles of technical drawing are codified in an international standard called ISO 128. The need for precise communication in the preparation of a functional document distinguishes technical drawing from the expressive drawing of the visual arts. Artistic drawings are subjectively interpreted; their meanin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Galileo Galilei
Galileo di Vincenzo Bonaiuti de' Galilei (15 February 1564 – 8 January 1642) was an Italian astronomer, physicist and engineer, sometimes described as a polymath. Commonly referred to as Galileo, his name was pronounced (, ). He was born in the city of Pisa, then part of the Duchy of Florence. Galileo has been called the "father" of observational astronomy, modern physics, the scientific method, and modern science. Galileo studied speed and velocity, gravity and free fall, the principle of relativity, inertia, projectile motion and also worked in applied science and technology, describing the properties of pendulums and "hydrostatic balances". He invented the thermoscope and various military compasses, and used the telescope for scientific observations of celestial objects. His contributions to observational astronomy include telescopic confirmation of the phases of Venus, observation of the four largest satellites of Jupiter, observation of Saturn's rings, and a ...

Francesco Barozzi
Francesco Barozzi (in Latin, ''Franciscus Barocius'') (9 August 1537 – 23 November 1604) was an Italian mathematician, astronomer and humanist. Life Barozzi was born on the island of Crete, at Candia (now Heraklion), at the time a Venetian possession. He was the son of Iacopo Barozzi, a Venetian nobleman, and Fiordiligi Dorro. Barozzi was educated at Padua, and studied mathematics at the University of Padua. The estate on Crete, inherited from his father, yielded him an income of 4,000 ducats, though he seems to have lived in Venice for most of his life. He was thus able to function as an independent scholar, and does not appear to have held any academic posts, although he did lecture on the '' De sphaera'' of Sacrobosco at the University of Padua in 1559. Barozzi translated many works of the ancients, including Proclus’s edition of Euclid's Elements (published in Venice in 1560), as well as mathematical works by Hero, Pappus of Alexandria, and Archimedes.

Bernardino Baldi
Bernardino Baldi (5 June 1553 – 10 October 1617) was an Italian mathematician, poet, translator and priest. Baldi descended from a noble family from Urbino, Marche, where he was born. He pursued his studies at Padua, and is said to have spoken about sixteen languages during his lifetime, though according to Tiraboschi the inscription on his tomb limits the number to twelve. The appearance of the plague at Padua forced him to return to his native city. Shortly afterwards he was called to act as tutor to Ferrante Gonzaga, from whom he received the rich abbey of Guastalla. The oldest biography of Nicolaus Copernicus was completed on 7 October 1588 by him.On the revolutions, Foundations of natural history, Band 1, p.335, Nicolaus Copernicus: Complete Works, Edward Rosen, Johns Hopkins University Press, 1992. He held office as abbot for 25 years, and then returned once again to Urbino. In 1612 he was employed by the duke as his envoy to Venice. Baldi died at Urbino on 12 October 16 ...

Federico Commandino
Federico Commandino (1509 – 5 September 1575) was an Italian humanist and mathematician. Born in Urbino, he studied at Padua and at Ferrara, where he received his doctorate in medicine. He was most famous for his central role as translator of works of ancient mathematicians. In this, his sources were primarily written in Greek and secondarily in Arabic, while his translations were primarily in Latin and secondarily in Italian. He was responsible for the publication of many treatises of Archimedes. He also translated the works of Aristarchus of Samos (''On the sizes and distances of the Sun and the Moon''), Pappus of Alexandria (''Mathematical collection''), Hero of Alexandria (''Pneumatics''), Ptolemy of Alexandria (''Planisphere'' and ''Analemma''), Apollonius of Perga (''Conics'') and Euclid of Alexandria (''Elements''). Among his pupils was Guidobaldo del Monte and Bernardino Baldi. Commandino maintained a correspondence with the astronomer Francesco Maurolico. The proposit ...
