Johannes Kepler
Johannes Kepler (; ; 27 December 1571 – 15 November 1630) was a German astronomer, mathematician, astrologer, natural philosopher and writer on music. He is a key figure in the 17th-century Scientific Revolution, best known for his laws of planetary motion, and his books ''Astronomia nova'', ''Harmonice Mundi'', and ''Epitome Astronomiae Copernicanae''. These works also provided one of the foundations for Newton's theory of universal gravitation. Kepler was a mathematics teacher at a seminary school in Graz, where he became an associate of Prince Hans Ulrich von Eggenberg. Later he became an assistant to the astronomer Tycho Brahe in Prague, and eventually the imperial mathematician to Emperor Rudolf II and his two successors Matthias and Ferdinand II. He also taught mathematics in Linz, and was an adviser to General Wallenstein. Additionally, he did fundamental work in the field of optics, invented an improved version of the refracting (or Keplerian) telescope, an ...

Spontaneous Generation
Spontaneous generation is a superseded scientific theory that held that living creatures could arise from nonliving matter and that such processes were commonplace and regular. It was hypothesized that certain forms, such as fleas, could arise from inanimate matter such as dust, or that maggots could arise from dead flesh. The doctrine of spontaneous generation was coherently synthesized by Aristotle, who compiled and expanded the work of earlier natural philosophers and the various ancient explanations for the appearance of organisms. Spontaneous generation was taken as scientific fact for two millennia. Though challenged in the 17th and 18th centuries by the experiments of Francesco Redi and Lazzaro Spallanzani, it was not discredited until the work of the French chemist Louis Pasteur and the Irish physicist John Tyndall in the mid-19th century. Rejection of spontaneous generation is no longer controversial among biologists. By the middle of the 19th century, experiments by Pa ...

Mathematician
A mathematician is someone who uses an extensive knowledge of mathematics in their work, typically to solve mathematical problems. Mathematicians are concerned with numbers, data, quantity, structure, space, models, and change. History One of the earliest known mathematicians were Thales of Miletus (c. 624–c.546 BC); he has been hailed as the first true mathematician and the first known individual to whom a mathematical discovery has been attributed. He is credited with the first use of deductive reasoning applied to geometry, by deriving four corollaries to Thales' Theorem. The number of known mathematicians grew when Pythagoras of Samos (c. 582–c. 507 BC) established the Pythagorean School, whose doctrine it was that mathematics ruled the universe and whose motto was "All is number". It was the Pythagoreans who coined the term "mathematics", and with whom the study of mathematics for its own sake begins. The first woman mathematician recorded by history was Hypati ...

Luca Valerio
Luca Valerio (1553–1618) was an Italian mathematician. He developed ways to find volumes and centers of gravity of solid bodies using the methods of Archimedes. He corresponded with Galileo Galilei and was a member of the Accademia dei Lincei. Biography Luca Valerio was born in Naples in 1553 He entered in the Jesuit order in 1570. He studied philosophy and theology at the Roman College as a student of Christopher Clavius, and left the Jesuits in 1580. He later taught rhetoric and Greek at the Collegio Pontifico Greco and mathematics and ethics at the Sapienza University of Rome. In 1611 Valerio obtained a position in the Vatican library in addition to his post at Sapienza giving him close connection with the top people in the Roman Catholic church. Galileo and Copernicus Valerio met Galileo on a visit to Pisa in 1584. He corresponded with Galileo from 1609 until 1616 and in 1612 he became a member of the Accademia dei Lincei, a group which also included Galileo as a m ...

Walter Raleigh
Sir Walter Raleigh (; – 29 October 1618) was an English statesman, soldier, writer and explorer. One of the most notable figures of the Elizabethan era, he played a leading part in English colonisation of North America, suppressed rebellion in Ireland, helped defend England against the Spanish Armada and held political positions under Elizabeth I. Raleigh was born to a Protestant family in Devon, the son of Walter Raleigh and Catherine Champernowne. He was the younger half-brother of Sir Humphrey Gilbert and a cousin of Sir Richard Grenville. Little is known of his early life, though in his late teens he spent some time in France taking part in the religious civil wars. In his 20s he took part in the suppression of rebellion in the colonisation of Ireland; he also participated in the siege of Smerwick. Later, he became a landlord of property in Ireland and mayor of Youghal in East Munster, where his house still stands in Myrtle Grove. He rose rapidly in the favour of Quee ...

James Lancaster
Sir James Lancaster (c. 1554 – 6 June 1618) was an English privateer and trader of the Elizabethan era. Life and work Lancaster came from Basingstoke in Hampshire. In his early life, he was a soldier and a trader in Portugal. On 10 April 1591 Lancaster started from Torbay in Devon, with George Raymond and Samuel Foxcroft, on his major voyage to the East Indies; this fleet of three ships (''Penelope'', ''Marchant Royal'' and ''Edward Bonaventure'') was the earliest of the English overseas Indian expeditions. They reached Table Bay on 1 August 1591. Losing one ship off Cape Correntes on 12 September, the squadron rested and refitted at Zanzibar (February 1592), rounded Cape Comorin the following May, and reached the Malay Peninsula having arrived at Penang in June. Here Lancaster remained on the island until September of the same year. After a later crossing to Ceylon, the crews insisted on returning home. The return voyage was disastrous, with only twenty-five officers and m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Jeremiah Horrocks
Jeremiah Horrocks (16183 January 1641), sometimes given as Jeremiah Horrox (the Latinised version that he used on the Emmanuel College register and in his Latin manuscripts), – See footnote 1 was an English astronomer. He was the first person to demonstrate that the Moon moved around the Earth in an elliptical orbit; and he was the only person to predict the transit of Venus of 1639, an event which he and his friend William Crabtree were the only two people to observe and record. Most remarkably, Horrocks (correctly) asserted that Jupiter was accelerating in its orbit while Saturn was slowing and interpreted this as due to mutual gravitational interaction, thereby demonstrating that gravity's actions were not limited to the Earth, Sun, and Moon. His early death and the chaos of the English Civil War nearly resulted in the loss to science of his treatise on the transit, ''Venus in sole visa''; but for this and his other work he is acknowledged as one of the founding fathers o ...

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 ...

Francesco Maria Grimaldi
Francesco Maria Grimaldi, SJ (2 April 1618 – 28 December 1663) was an Italian Jesuit priest, mathematician and physicist who taught at the Jesuit college in Bologna. He was born in Bologna to Paride Grimaldi and Anna Cattani. Work Between 1640 and 1650, working with Riccioli, he investigated the free fall of objects, confirming that the distance of fall was proportional to the square of the time taken. Grimaldi and Riccioli also made a calculation of gravity at the earth's surface by recording the oscillations of an accurate pendulum. In astronomy, he built and used instruments to measure lunar mountains as well as the height of clouds, and drew an accurate map or, ''selenograph'', which was published by Riccioli and now adorns the entrance to the National Air and Space Museum in Washington D.C. He was the first to make accurate observations on the diffraction of light (although by some accounts Leonardo da Vinci had earlier noted it), and coined the word 'diffraction'. T ...

Royal Pharmaceutical Society Of Great Britain
The Royal Pharmaceutical Society of Great Britain (RPSGB) existed from its founding as the Pharmaceutical Society of Great Britain in 1841 until 2010. The word "Royal" was added to its name in 1988. It was the statutory regulatory and professional body for pharmacists and pharmacy technicians in England, Scotland and Wales. In September 2010, the regulatory powers of the Society were transferred to the newly formed General Pharmaceutical Council (GPhC). The RPSGB became the Royal Pharmaceutical Society (RPS) at that time and retained its professional leadership role; the "Great Britain" part of the name was dropped for day-to-day purposes. Statutory role Before the establishment of the GPhC and the transfer of regulatory power, the primary objective of the RPSGB was to lead, regulate, develop and promote the pharmaceutical profession. All pharmacists in Great Britain had to be registered with the Society in order to practise, and the Society was unusual amongst healthcare regulat ...
