Galileo Macchie Solari
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 ...

Ostilio Ricci Da Fermo
Ostilio Ricci da Fermo (1540–1603) was an Italian mathematician. Biography He was a university professor in Florence at the Accademia delle Arti del Disegno, founded in 1560 by Giorgio Vasari. Ricci is also known for being Galileo Galilei's teacher. Ricci was the Court Mathematician to the Grand Duke Francesco in Florence, in 1580, when Galileo attended his lectures in Pisa. Galileo was enrolled at the University of Pisa, by his father Vincenzo, in order to study medicine. Instead, Galilei became more interested in mathematics, after meeting Ostilio Ricci, a former student of Niccolò Tartaglia. Ricci taught Galileo the mathematics of Euclid and Archimedes Archimedes of Syracuse (;; ) was a Greek mathematician, physicist, engineer, astronomer, and inventor from the ancient city of Syracuse in Sicily. Although few details of his life are known, he is regarded as one of the leading scientists ..., who both deeply influenced Galileo's later work. Ricci considered mat ...

Physicist
A physicist is a scientist who specializes in the field of physics, which encompasses the interactions of matter and energy at all length and time scales in the physical universe. Physicists generally are interested in the root or ultimate causes of phenomena, and usually frame their understanding in mathematical terms. Physicists work across a wide range of research fields, spanning all length scales: from sub-atomic and particle physics, through biological physics, to cosmological length scales encompassing the universe as a whole. The field generally includes two types of physicists: experimental physicists who specialize in the observation of natural phenomena and the development and analysis of experiments, and theoretical physicists who specialize in mathematical modeling of physical systems to rationalize, explain and predict natural phenomena. Physicists can apply their knowledge towards solving practical problems or to developing new technologies (also known as applie ...

Astronomer
An astronomer is a scientist in the field of astronomy who focuses their studies on a specific question or field outside the scope of Earth. They observe astronomical objects such as stars, planets, natural satellite, moons, comets and galaxy, galaxies – in either observational astronomy, observational (by analyzing the data) or theoretical astronomy. Examples of topics or fields astronomers study include planetary science, Sun, solar astronomy, the Star formation, origin or stellar evolution, evolution of stars, or the galaxy formation and evolution, formation of galaxies. A related but distinct subject is physical cosmology, which studies the Universe as a whole. Types Astronomers usually fall under either of two main types: observational astronomy, observational and theoretical astronomy, theoretical. Observational astronomers make direct observations of Astronomical object, celestial objects and analyze the data. In contrast, theoretical astronomers create and investigate C ...

Blason De Galilée (Galileo Galilei)
Blason is a form of poetry. The term originally comes from the heraldic term "blazon" in French heraldry, which means either the codified description of a coat of arms or the coat of arms itself. The Dutch term is Blazoen, and in either Dutch or French, the term is often used to refer to the coat of arms of a chamber of rhetoric. History The term forms the root of the modern words "emblazon", which means to celebrate or adorn with heraldic markings, and "blazoner", one who emblazons. The terms "blason", "blasonner", "blasonneur" were used in 16th-century French literature by poets who, following Clément Marot in 1536, practised a genre of poems that praised a woman by singling out different parts of her body and finding appropriate metaphors to compare them with. It is still being used with that meaning in literature and especially in poetry. One famous example of such a celebratory poem, ironically rejecting each proposed stock metaphor, is William Shakespeare's Sonnet 130: :' ...

Observational Astronomy
Observational astronomy is a division of astronomy that is concerned with recording data about the observable universe, in contrast with theoretical astronomy, which is mainly concerned with calculating the measurable implications of physical models. It is the practice and study of observation, observing celestial objects with the use of telescopes and other astronomical instruments. As a space science, science, the study of astronomy is somewhat hindered in that direct experiments with the properties of the distant universe are not possible. However, this is partly compensated by the fact that astronomers have a vast number of visible examples of stellar phenomena that can be examined. This allows for observational data to be plotted on graphs, and general trends recorded. Nearby examples of specific phenomena, such as variable stars, can then be used to infer the behavior of more distant representatives. Those distant yardsticks can then be employed to measure other phenomena ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kinematics
Kinematics is a subfield of physics, developed in classical mechanics, that describes the Motion (physics), motion of points, Physical object, bodies (objects), and systems of bodies (groups of objects) without considering the forces that cause them to move. Kinematics, as a field of study, is often referred to as the "geometry of motion" and is occasionally seen as a branch of mathematics. A kinematics problem begins by describing the geometry of the system and declaring the initial conditions of any known values of position, velocity and/or acceleration of points within the system. Then, using arguments from geometry, the position, velocity and acceleration of any unknown parts of the system can be determined. The study of how forces act on bodies falls within kinetics (physics), kinetics, not kinematics. For further details, see analytical dynamics. Kinematics is used in astrophysics to describe the motion of celestial bodies and collections of such bodies. In mechanical engin ...

Heliocentrism
Heliocentrism (also known as the Heliocentric model) is the astronomical model in which the Earth and planets revolve around the Sun at the center of the universe. Historically, heliocentrism was opposed to geocentrism, which placed the Earth at the center. The notion that the Earth revolves around the Sun had been proposed as early as the third century BC by Aristarchus of Samos, who had been influenced by a concept presented by Philolaus of Croton (c. 470 – 385 BC). In the 5th century BC the Greek Philosophers Philolaus and Hicetas had the thought on different occasions that our Earth was spherical and revolving around a "mystical" central fire, and that this fire regulated the universe. In medieval Europe, however, Aristarchus' heliocentrism attracted little attention—possibly because of the loss of scientific works of the Hellenistic period. It was not until the sixteenth century that a mathematical model of a heliocentric system was presented by the Renaissance mathema ...

Analytical Dynamics
In classical mechanics, analytical dynamics, also known as classical dynamics or simply dynamics, is concerned with the relationship between motion of bodies and its causes, namely the forces acting on the bodies and the properties of the bodies, particularly mass and moment of inertia. The foundation of modern-day dynamics is Newtonian mechanics and its reformulation as Lagrangian mechanics and Hamiltonian mechanics. History The field has a long and important history, as remarked by Hamilton: "The theoretical development of the laws of motion of bodies is a problem of such interest and importance that it has engaged the attention of all the eminent mathematicians since the invention of the dynamics as a mathematical science by Galileo, and especially since the wonderful extension which was given to that science by Newton." William Rowan Hamilton, 1834 (Transcribed in ''Classical Mechanics'' by J.R. Taylor, p. 237) Some authors (for example, Taylor (2005) and Greenwood (19 ...

Mario Guiducci
Mario Guiducci (Florence 18 March 1583 - Florence 5 November 1646) was an Italian scholar and writer. A friend and colleague of Galileo, he collaborated with him on the ''Discourse on Comets'' in 1618. Early life Mario Guiducci was born in the San Frediano quarter of Florence. His father was Alessandro Guiducci, son of a senator, and his mother was Camilla Capponi. He had at least two brothers, Giulio, who died in 1654 and Simone, as well as a sister, Maddalena, who married Orazio Cavalcanti. He was sent to the Jesuit College in Rome as a boy. He never appears to have earned his doctorate in philosophy at Rome, but he did become a Doctor of both laws at the university of Pisa on 27 May 1610. At some time, probably after this, he became a pupil either of Benedetto Castelli, or, possibly, of Galileo himself. Disputes about comets, 1618-20 In 1618, the year Guiducci became consul of the Accademia Fiorentina, a particularly bright and long-lasting comet was seen in the skies over E ...
