Virgilio Trettenero
Virgilio Trettenero (4 February 1822 – 23 May 1863) was an Italian mathematician and astronomer born in Recoaro Terme, Province of Vicenza, Italy. Active between 1848–1863, his name is linked to the creation of the stellar catalogs, a work initiated by Giovanni Padovani in 1838 using the meridian circle, which he purchased. The asteroid 16715 Trettenero, discovered on 20 October 1995 at the San Vittore Observatory, in Bologna, was named so in his honour. Life Son of Domenico, owner of a hotel, and Domenica Maltauro, he studied at the University of Padua. In 1848 he appeared in the journal ''Astronomische Nachrichten'' connected to an article about the observations of the planet Neptune. The presence of the planet was postulated on the basis of the perturbation of the orbit of Uranus by Le Verrier and was observed for the first time only two years earlier. In 1850-1851 he was nominated assistant in the department of physics and geodesy in Padua, and assistant ast ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Recoaro Terme
Recoaro Terme (Cimbrian: 'Recobör'', ''Rocabör'' o ''Ricaber' ) is a town and ''comune'' in the province of Vicenza, Veneto, Italy. It is known for his mineral spring waters: ''Lora'' is bottled and commercialized, while some of the others are used for hydrotherapy in ''Terme Recoaro'' Spa. History The area of Recoaro was settled in the 13th century by German colonists, a document mentioning a ''villa'' in Rovegliana (now a ''frazione'' of Recoaro) in 1262. Later it was under the Scaliger, the Visconti of Milan and then under the Republic of Venice, to which it belonged until the late 18th century. In 1689 thermal waters were discovered, which led to the development of Recoaro as a tourist resort in the following century, although most of the population lived on agriculture until the 19th century. After being part of the Austrian puppet Kingdom of Lombardy–Venetia, Recoaro became part of the unified Kingdom of Italy in 1866. Friedrich Nietzsche sojourned here in 1881 and a ...

Giovanni Sante Gaspero Santini
Giovanni Sante Gaspero Santini (b. Caprese in Tuscany, 30 June 1786; d. Noventa Padovana, 26 June 1877) was an Italian astronomer and mathematician. He received his first instruction from his parental uncle, the Abbot Giovanni Battista Santini. After finishing his philosophical studies in the school year 1801-2, at the seminary of Prato, he entered in 1802 the University of Pisa. He very soon abandoned the study of law in order to devote himself, under the direction of Prof. Paoli and Abbot Pacchiano, exclusively to mathematics and the natural sciences. It appears that at Pisa, Santini still wore the cassock, with the consequence that in bibliographical dictionaries he still figures under the title of ''abate''. It is certain, however, that he never received major orders. In 1810 he married Teresa Pastrovich, and one year after her death, in 1843, he contracted a second marriage with Adriana Conforti, who outlived him. During his stay in Pisa he became friendly with the re ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
People From The Province Of Vicenza
A person ( : people) is a being that has certain capacities or attributes such as reason, morality, consciousness or self-consciousness, and being a part of a culturally established form of social relations such as kinship, ownership of property, or legal responsibility. The defining features of personhood and, consequently, what makes a person count as a person, differ widely among cultures and contexts. In addition to the question of personhood, of what makes a being count as a person to begin with, there are further questions about personal identity and self: both about what makes any particular person that particular person instead of another, and about what makes a person at one time the same person as they were or will be at another time despite any intervening changes. The plural form "people" is often used to refer to an entire nation or ethnic group (as in "a people"), and this was the original meaning of the word; it subsequently acquired its use as a plural form of per ...

Ephemerides
In astronomy and celestial navigation, an ephemeris (pl. ephemerides; ) is a book with tables that gives the trajectory of naturally occurring astronomical objects as well as artificial satellites in the sky, i.e., the position (and possibly velocity) over time. Historically, positions were given as printed tables of values, given at regular intervals of date and time. The calculation of these tables was one of the first applications of mechanical computers. Modern ephemerides are often provided in electronic form. However, printed ephemerides are still produced, as they are useful when computational devices are not available. The astronomical position calculated from an ephemeris is often given in the spherical polar coordinate system of right ascension and declination, together with the distance from the origin if applicable. Some of the astronomical phenomena of interest to astronomers are eclipses, apparent retrograde motion/planetary stations, planetary es, sidereal time ...

Eclipses
An eclipse is an astronomical event that occurs when an astronomical object or spacecraft is temporarily obscured, by passing into the shadow of another body or by having another body pass between it and the viewer. This alignment of three celestial objects is known as a syzygy. Apart from syzygy, the term eclipse is also used when a spacecraft reaches a position where it can observe two celestial bodies so aligned. An eclipse is the result of either an occultation (completely hidden) or a transit (partially hidden). The term eclipse is most often used to describe either a solar eclipse, when the Moon's shadow crosses the Earth's surface, or a lunar eclipse, when the Moon moves into the Earth's shadow. However, it can also refer to such events beyond the Earth–Moon system: for example, a planet moving into the shadow cast by one of its moons, a moon passing into the shadow cast by its host planet, or a moon passing into the shadow of another moon. A binary star system can a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Comets
A comet is an icy, small Solar System body that, when passing close to the Sun, warms and begins to release gases, a process that is called outgassing. This produces a visible atmosphere or coma, and sometimes also a tail. These phenomena are due to the effects of solar radiation and the solar wind acting upon the nucleus of the comet. Comet nuclei range from a few hundred meters to tens of kilometers across and are composed of loose collections of ice, dust, and small rocky particles. The coma may be up to 15 times Earth's diameter, while the tail may stretch beyond one astronomical unit. If sufficiently bright, a comet may be seen from Earth without the aid of a telescope and may subtend an arc of 30° (60 Moons) across the sky. Comets have been observed and recorded since ancient times by many cultures and religions. Comets usually have highly eccentric elliptical orbits, and they have a wide range of orbital periods, ranging from several years to potentially several milli ...

Asteroids
An asteroid is a minor planet of the inner Solar System. Sizes and shapes of asteroids vary significantly, ranging from 1-meter rocks to a dwarf planet almost 1000 km in diameter; they are rocky, metallic or icy bodies with no atmosphere. Of the roughly one million known asteroids the greatest number are located between the orbits of Mars and Jupiter, approximately 2 to 4 AU from the Sun, in the main asteroid belt. Asteroids are generally classified to be of three types: C-type, M-type, and S-type. These were named after and are generally identified with carbonaceous, metallic, and silicaceous compositions, respectively. The size of asteroids varies greatly; the largest, Ceres, is almost across and qualifies as a dwarf planet. The total mass of all the asteroids combined is only 3% that of Earth's Moon. The majority of main belt asteroids follow slightly elliptical, stable orbits, revolving in the same direction as the Earth and taking from three to six years to comple ...

Veneto
Veneto (, ; vec, Vèneto ) or Venetia is one of the 20 regions of Italy. Its population is about five million, ranking fourth in Italy. The region's capital is Venice while the biggest city is Verona. Veneto was part of the Roman Empire until the 5th century AD. Later, after a Feudalism, feudal period, it was part of the Republic of Venice until 1797. Venice ruled for centuries over one of the largest and richest maritime republics and trade empires in the world. After the Napoleonic Wars and the Congress of Vienna, the Republic was combined with Lombardy and annexed to the Austrian Empire as the Kingdom of Lombardy–Venetia, until that was Italian unification, merged with the Kingdom of Italy in 1866, as a result of the Third Italian War of Independence. Besides Italian language, Italian, most inhabitants also speak Venetian language, Venetian. Since 1971, the Statute of Veneto has referred to the region's citizens as "the Venetian people". Article 1 defines Veneto as an " ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Philosophy
Philosophy (from , ) is the systematized study of general and fundamental questions, such as those about existence, reason, knowledge, values, mind, and language. Such questions are often posed as problems to be studied or resolved. Some sources claim the term was coined by Pythagoras ( BCE), although this theory is disputed by some. Philosophical methods include questioning, critical discussion, rational argument, and systematic presentation. in . Historically, ''philosophy'' encompassed all bodies of knowledge and a practitioner was known as a ''philosopher''."The English word "philosophy" is first attested to , meaning "knowledge, body of knowledge." "natural philosophy," which began as a discipline in ancient India and Ancient Greece, encompasses astronomy, medicine, and physics. For example, Newton's 1687 ''Mathematical Principles of Natural Philosophy'' later became classified as a book of physics. In the 19th century, the growth of modern research universiti ...

Mathematics
Mathematics is an area of knowledge that includes the topics of numbers, formulas and related structures, shapes and the spaces in which they are contained, and quantities and their changes. These topics are represented in modern mathematics with the major subdisciplines of number theory, algebra, geometry, and analysis, respectively. There is no general consensus among mathematicians about a common definition for their academic discipline. Most mathematical activity involves the discovery of properties of abstract objects and the use of pure reason to prove them. These objects consist of either abstractions from nature orin modern mathematicsentities that are stipulated to have certain properties, called axioms. A ''proof'' consists of a succession of applications of deductive rules to already established results. These results include previously proved theorems, axioms, andin case of abstraction from naturesome basic properties that are considered true starting points of ...
