Barnaba Oriani
Barnaba Oriani Royal Society of London, FRS FRSE (17 July 1752 – 12 November 1832) was an Italian priest, geodesist, astronomer and scientist. Life Oriani was born in Garegnano (now part of Milan), the son of a mason, and died in Milan. After getting his elementary education in Garegnano, he went on to study at the College of San Alessandro in Milan, under the tutelage and with the support of the Barnabites, Order of Barnabites, which he later joined. After completing his studies in the humanities, physical sciences, physical and mathematics, mathematical sciences, philosophy, and theology, he was ordained a priest in 1775. When Napoleon I established the Republic of Lombardy, Oriani refused to swear an oath against the monarchy, and the new republican government modified the oath of allegiance on his behalf. He was retained in his position at the observatory and was made president of the commission appointed to regulate the new system of weights and measures. When the re ...

Milan
Milan ( , , Lombard: ; it, Milano ) is a city in northern Italy, capital of Lombardy, and the second-most populous city proper in Italy after Rome. The city proper has a population of about 1.4 million, while its metropolitan city has 3.26 million inhabitants. Its continuously built-up urban area (whose outer suburbs extend well beyond the boundaries of the administrative metropolitan city and even stretch into the nearby country of Switzerland) is the fourth largest in the EU with 5.27 million inhabitants. According to national sources, the population within the wider Milan metropolitan area (also known as Greater Milan), is estimated between 8.2 million and 12.5 million making it by far the largest metropolitan area in Italy and one of the largest in the EU.* * * * Milan is considered a leading alpha global city, with strengths in the fields of art, chemicals, commerce, design, education, entertainment, fashion, finance, health ...

Weights And Measures
A unit of measurement is a definite magnitude of a quantity, defined and adopted by convention or by law, that is used as a standard for measurement of the same kind of quantity. Any other quantity of that kind can be expressed as a multiple of the unit of measurement. For example, a length is a physical quantity. The metre (symbol m) is a unit of length that represents a definite predetermined length. For instance, when referencing "10 metres" (or 10 m), what is actually meant is 10 times the definite predetermined length called "metre". The definition, agreement, and practical use of units of measurement have played a crucial role in human endeavour from early ages up to the present. A multitude of systems of units used to be very common. Now there is a global standard, the International System of Units (SI), the modern form of the metric system. In trade, weights and measures is often a subject of governmental regulation, to ensure fairness and transparency. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Refraction
In physics, refraction is the redirection of a wave as it passes from one medium to another. The redirection can be caused by the wave's change in speed or by a change in the medium. Refraction of light is the most commonly observed phenomenon, but other waves such as sound waves and water waves also experience refraction. How much a wave is refracted is determined by the change in wave speed and the initial direction of wave propagation relative to the direction of change in speed. For light, refraction follows Snell's law, which states that, for a given pair of media, the ratio of the sines of the angle of incidence ''θ1'' and angle of refraction ''θ2'' is equal to the ratio of phase velocities (''v''1 / ''v''2) in the two media, or equivalently, to the refractive indices (''n''2 / ''n''1) of the two media. :\frac =\frac=\frac Optical prisms and lenses use refraction to redirect light, as does the human eye. The refractive index of materials varies with the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ephemeris
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 t ...

Osservatorio Astronomico Di Brera
The Brera Observatory ( it, Osservatorio Astronomico di Brera) is an astronomical observatory in the Brera district of Milan, Italy. It was built in the historic Palazzo Brera in 1764 by the Jesuit astronomer Roger Boscovich. Following the suppression of the Jesuits by Clement XIV on 21 July 1773, the palace and the observatory passed to the then rulers of northern Italy, the Austrian Habsburg dynasty. From 1 December 1786, the Austrian Empire adopted “transalpine time”. The astronomers were engaged by Count Giuseppe Di Wilczek, the plenipotentiary governor of Lombardy, to build a meridian line inside Milan Cathedral. It was constructed by Giovanni Angelo Cesaris and Francesco Reggio, with Roger Joseph Boscovich acting as a consultant. Following the independence of Italy in 1861, the observatory has been run by the Italian government. In 1862, the newly installed Italian government improved the observatory's facilities by commissioning a 218mm Merz Equatorial Refracting T ...

Ceres (dwarf Planet)
Ceres (; minor-planet designation: 1 Ceres) is a dwarf planet in the asteroid belt between the orbits of Mars and Jupiter. It was the first asteroid discovered, on 1 January 1801, by Giuseppe Piazzi at Palermo Astronomical Observatory in Sicily and announced as a new planet. Ceres was later classified as an asteroid and then a dwarf planetthe only one always inside Neptune's orbit. Ceres's small size means that even at its brightest, it is too dim to be seen by the naked eye, except under extremely dark skies. Its apparent magnitude ranges from 6.7 to 9.3, peaking at opposition (when it is closest to Earth) once every 15- to 16-month synodic period. As a result, its surface features are barely visible even with the most powerful telescopes, and little was known about it until the robotic NASA spacecraft ''Dawn'' approached Ceres for its orbital mission in 2015. ''Dawn'' found Ceres's surface to be a mixture of water ice, and hydrated minerals such as carbonates and cl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Giuseppe Piazzi
Giuseppe Piazzi ( , ; 16 July 1746 – 22 July 1826) was an Italian Catholic priest of the Theatine order, mathematician, and astronomer. He established an observatory at Palermo, now the '' Osservatorio Astronomico di Palermo – Giuseppe S. Vaiana''. Perhaps his most famous discovery was the first dwarf planet, Ceres. Early life No documented account of Piazzi's scientific education is available in any of the biographies of the astronomer, even in the oldest ones. Piazzi certainly did some studies in Turin, quite likely attending Giovan Battista Beccaria's lessons. In the years 1768–1770 he was resident at the Theatines' Home in S. Andrea della Valle, Rome, while studying Mathematics under François Jacquier. In July 1770, he took the chair of Mathematics at the University of Malta. In December 1773, he moved to Ravenna as "prefetto degli studenti" and lecturer in Philosophy and Mathematics at the Collegio dei Nobili, where he stayed until the beginning of 1779. ...

Theatine
The Theatines officially named the Congregation of Clerics Regular ( la, Ordo Clericorum Regularium), abreviated CR, is a Catholic order of clerics regular of Pontifical Right for men founded by Archbishop Gian Pietro Carafa in Sept. 14, 1524. Its members add the nominal letters C.R. after their names to indicate their membership in the Congregation. Foundation The order was founded by Saint Cajetan (Gaetano dei Conti di Thiene), Paolo Consiglieri, Bonifacio da Colle, and Giovanni Pietro Carafa (afterwards Pope Paul IV). Carafa was Bishop of Chieti; Chieti (Theate) is a city of the Abruzzi in Central Italy, from which the congregation adopted its specific name, to distinguish it from other congregations (Barnabites, Somaschi, Caracciolini, etc.) modelled upon it. The Theatines combined the pursuit of evangelical perfection traditional among religious orders with apostolic service generally expected of diocesan clergy. It was Caraffa who wrote the constitutions of the order. Caj ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Rimini
Rimini ( , ; rgn, Rémin; la, Ariminum) is a city in the Emilia-Romagna region of northern Italy and capital city of the Province of Rimini. It sprawls along the Adriatic Sea, on the coast between the rivers Marecchia (the ancient ''Ariminus'') and Ausa (ancient ''Aprusa''). It is one of the most notable seaside resorts in Europe with revenue from both internal and international tourism forming a significant portion of the city's economy. It is also near San Marino, a small nation within Italy. The first bathing establishment opened in 1843. Rimini is an art city with ancient Roman and Renaissance monuments, and is also the birthplace of the film director Federico Fellini. The city was founded by the Romans in 268 BC. Throughout Roman times, Rimini was a key communications link between the north and south of the peninsula. On its soil, Roman emperors erected monuments such as the Arch of Augustus and the Tiberius Bridge to mark the beginning and the end of the Decumanus ...

Arc Of The Meridian
In geodesy and navigation, a meridian arc is the curve between two points on the Earth's surface having the same longitude. The term may refer either to a segment of the meridian, or to its length. The purpose of measuring meridian arcs is to determine a figure of the Earth. One or more measurements of meridian arcs can be used to infer the shape of the reference ellipsoid that best approximates the geoid in the region of the measurements. Measurements of meridian arcs at several latitudes along many meridians around the world can be combined in order to approximate a ''geocentric ellipsoid'' intended to fit the entire world. The earliest determinations of the size of a spherical Earth required a single arc. Accurate survey work beginning in the 19th century required several arc measurements in the region the survey was to be conducted, leading to a proliferation of reference ellipsoids around the world. The latest determinations use astro-geodetic measurements and the metho ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Senator
A senate is a deliberative assembly, often the upper house or chamber of a bicameral legislature. The name comes from the ancient Roman Senate (Latin: ''Senatus''), so-called as an assembly of the senior (Latin: ''senex'' meaning "the elder" or "old man") and therefore considered wiser and more experienced members of the society or ruling class. However the Roman Senate was not the ancestor or predecessor of modern parliamentarism in any sense, because the Roman senate was not a legislative body. Many countries have an assembly named a ''senate'', composed of ''senators'' who may be elected, appointed, have inherited the title, or gained membership by other methods, depending on the country. Modern senates typically serve to provide a chamber of "sober second thought" to consider legislation passed by a lower house, whose members are usually elected. Most senates have asymmetrical duties and powers compared with their respective lower house meaning they have special du ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
