Evangelista Torricelli
Evangelista Torricelli ( ; ; 15 October 160825 October 1647) was an Italian people, Italian physicist and mathematician, and a student of Benedetto Castelli. He is best known for his invention of the barometer, but is also known for his advances in optics and work on the method of indivisibles. The torr is named after him. Biography Early life Torricelli was born on 15 October 1608 in Rome, the firstborn child of Gaspare Ruberti and Giacoma Torricelli. His family was from Faenza in the Province of Ravenna, then part of the Papal States. His father was a textile worker and the family was very poor. Seeing his talents, his parents sent him to be educated in Faenza, under the care of his uncle, Giacomo (James), a Camaldolese monk, who first ensured that his nephew was given a sound basic education. He then entered young Torricelli into a Jesuit College in 1624, possibly the one in Faenza itself, to study mathematics and philosophy until 1626, by which time his father, Gaspare, had di ...

Lorenzo Lippi
Lorenzo Lippi (3 May 1606 – 15 April 1665) was an Italian Painting, painter and poet from Florence. Biography Born in Florence, he studied painting under Matteo Rosselli. Both Baldassare Franceschini and Francesco Furini were also apprenticed with Rosselli, the influence of whose style, and more especially of that of Santi di Tito, is to be traced in Lippi's works, which are marked by taste, delicacy and a strong turn for portrait-like naturalism (art), naturalism. His maxim was to poetize as he spoke, and to paint as he saw. His biography was recounted by Filippo Baldinucci. After painting for some time in Florence, and having married at the age of forty the daughter of the rich sculptor named Giovanni Francesco Susini, Lippi went as court painter to Innsbruck, where he has left many excellent portraits. In Innsbruck, he wrote his humorous poem named ''Il Malmantile racquistato'', which was published under the anagrammatic pseudonym of Perlone Zipoli. The ''Malmantile ra ...

Torricelli Point
In Euclidean geometry, the Fermat point of a triangle, also called the Torricelli point or Fermat–Torricelli point, is a point such that the sum of the three distances from each of the three vertices of the triangle to the point is the smallest possible or, equivalently, the geometric median of the three vertices. It is so named because this problem was first raised by Fermat in a private letter to Evangelista Torricelli, who solved it. The Fermat point gives a solution to the geometric median and Steiner tree problems for three points. Construction The Fermat point of a triangle with largest angle at most 120° is simply its first isogonic center or X(13), which is constructed as follows: # Construct an equilateral triangle on each of two arbitrarily chosen sides of the given triangle. # Draw a line from each new vertex to the opposite vertex of the original triangle. # The two lines intersect at the Fermat point. An alternative method is the following: # On each of two a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Jesuit
The Society of Jesus (; abbreviation: S.J. or SJ), also known as the Jesuit Order or the Jesuits ( ; ), is a religious order (Catholic), religious order of clerics regular of pontifical right for men in the Catholic Church headquartered in Rome. It was founded in 1540 by Ignatius of Loyola and six companions, with the approval of Pope Paul III. The Society of Jesus is the largest religious order in the Catholic Church and has played significant role in education, charity, humanitarian acts and global policies. The Society of Jesus is engaged in evangelization and apostolic ministry in 112 countries. Jesuits work in education, research, and cultural pursuits. They also conduct retreats, minister in hospitals and parishes, sponsor direct social and humanitarian works, and promote Ecumenism, ecumenical dialogue. The Society of Jesus is consecrated under the patron saint, patronage of Madonna della Strada, a title of the Blessed Virgin Mary, and it is led by a Superior General of ...

Monk
A monk (; from , ''monachos'', "single, solitary" via Latin ) is a man who is a member of a religious order and lives in a monastery. A monk usually lives his life in prayer and contemplation. The concept is ancient and can be seen in many religions and in philosophy across numerous cultures. The Greek word for "monk" may be applied to men or women. In English, however, "monk" is applied mainly to men, while ''nun'' is typically used for female monastics. Although the term ''monachos'' is of Christianity, Christian origin, in the English language ''monk'' tends to be used loosely also for both male and female ascetics from other religious or philosophical backgrounds. However, being generic, it is not interchangeable with terms that denote particular kinds of monk, such as cenobite, hermit, anchorite, or Hesychasm, hesychast. Traditions of Christian monasticism exist in major Christian denominations, with religious orders being present in Catholicism, Lutheranism, Oriental Ort ...

Camaldolese
The Camaldolese Hermits of Mount Corona () are a Catholic Church, Catholic monastic order of pontifical right for men founded by Romuald, St. Romuald. Its name is derived from the Holy Hermitage () in Camaldoli, high in the mountains of Tuscany, Tuscany, Italy, near the city of Arezzo. Members of that community add the postnominal letters ECMC after their names. A second community, the Benedictine Camaldolese, are also based at Camaldoli and add the postnominals OSB Cam. Apart from the Catholic monasteries, ecumenical Christian hermitages with a Camaldolese spirituality have arisen as well. History The Camaldolese were established through the efforts of the Italian people, Italian monk Saint Romuald (). His reform sought to renew and integrate the hermit, eremitical tradition of monastic life with that of the cenobium. In his youth, Romuald became acquainted with the three major schools of Western monastic tradition. The monastery where he first entered monastic life, Basilica ...

Province Of Ravenna
The province of Ravenna (; ) is a province in the Emilia-Romagna region of Italy. Its capital is the city of Ravenna. As of 2015, it has a population of 391,997 inhabitants over an area of , giving it a population density of 210.81 inhabitants per square kilometre. Its provincial president is Claudio Casadio. History Ravenna was first inhabited by Italic tribes from northern regions, and was conquered in 191 BCE by the Roman Republic. A port was constructed near Classe, and the Adriatic fleet was based in Ravenna. In 402 CE, Ravenna became the capital of the Western Roman Empire, which endured until the collapse of the empire and the fall of Rome in 476. Following this, the Barbarian Kings Odoacer and then Theodoric controlled Ravenna until it was conquered by the Byzantine Empire in 540; the Byzantines announced it to be their Exarchate. It continued to be under Byzantine rule until it was invaded by the Lombards in 751, and it was then annexed by King of the Franks Pippin the ...

Faenza
Faenza (, ; ; or ; ) is an Italian city and comune of 59,063 inhabitants in the province of Ravenna, Emilia-Romagna, situated southeast of Bologna. Faenza is home to a historical manufacture of majolica-ware glazed earthenware pottery, known from the French name of the town as ''faience''. Geography Faenza, at the foot of the first sub-Apennine hills, is surrounded by an agricultural region including vineyards in the hills, and cultivated land with traces of the ancient Roman land-division system, and fertile market gardens in the plains. In the nearby green valleys of the rivers Samoggia and Lamone there are great number of 18th and 19th century stately homes, set in extensive grounds or preceded by long cypress-lined driveways. History According to mythology, the name of the first settlement, ''Faoentia'', had Etruscan and Celtic roots, meaning in Latin "Splendeo inter deos" or "I shine among the gods", in modern English. The very name, coming from the Romans who develo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Torr
The torr (symbol: Torr) is a Pressure#Units, unit of pressure based on an absolute scale, defined as exactly of a standard atmosphere (unit), atmosphere (101325 Pa). Thus one torr is exactly (≈ ). Historically, one torr was intended to be the same as one "millimetre of mercury", but subsequent redefinitions of the two units of measurement, units made the torr marginally lower (by less than 0.000015%). The torr is not part of the International System of Units (SI). Even so, it is often combined with the metric prefix milli to name one millitorr (mTorr), equal to 0.001 Torr. The unit was named after Evangelista Torricelli, an Italian physicist and mathematician who discovered the principle of the barometer in 1644. Nomenclature and common errors The unit name ''torr'' is written in letter case, lower case, while its symbol ("Torr") is always written with an uppercase initial; including in combinations with prefixes and other unit symbols, as in "mTorr" (millitorr) or " ...

Method Of Indivisibles
In geometry, Cavalieri's principle, a modern implementation of the method of indivisibles, named after Bonaventura Cavalieri, is as follows: * 2-dimensional case: Suppose two regions in a plane are included between two parallel lines in that plane. If every line parallel to these two lines intersects both regions in line segments of equal length, then the two regions have equal areas. * 3-dimensional case: Suppose two regions in three-space (solids) are included between two parallel planes. If every plane parallel to these two planes intersects both regions in cross section (geometry), cross-sections of equal area, then the two regions have equal volumes. Today Cavalieri's principle is seen as an early step towards integral calculus, and while it is used in some forms, such as its generalization in Fubini's theorem and layer cake representation, results using Cavalieri's principle can often be shown more directly via integration. In the other direction, Cavalieri's principle gre ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Optics
Optics is the branch of physics that studies the behaviour and properties of light, including its interactions with matter and the construction of optical instruments, instruments that use or Photodetector, detect it. Optics usually describes the behaviour of visible light, visible, ultraviolet, and infrared light. Light is a type of electromagnetic radiation, and other forms of electromagnetic radiation such as X-rays, microwaves, and radio waves exhibit similar properties. Most optical phenomena can be accounted for by using the Classical electromagnetism, classical electromagnetic description of light, however complete electromagnetic descriptions of light are often difficult to apply in practice. Practical optics is usually done using simplified models. The most common of these, geometric optics, treats light as a collection of Ray (optics), rays that travel in straight lines and bend when they pass through or reflect from surfaces. Physical optics is a more comprehensive mo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Barometer
A barometer is a scientific instrument that is used to measure air pressure in a certain environment. Pressure tendency can forecast short term changes in the weather. Many measurements of air pressure are used within surface weather analysis to help find surface Trough (meteorology), troughs, pressure systems and weather front, frontal boundaries. Barometers and pressure altimeters (the most basic and common type of altimeter) are essentially the same instrument, but used for different purposes. An altimeter is intended to be used at different levels matching the corresponding atmospheric pressure to the altitude, while a barometer is kept at the same level and measures subtle pressure changes caused by weather and elements of weather. The average atmospheric pressure on the Earth's surface varies between 940 and 1040 hPa (mbar). The average atmospheric pressure at sea level is 1013 hPa (mbar). Etymology The word ''wikt:barometer, barometer'' is derived from the Ancient Gr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
