René Antoine Ferchault De Réaumur
René Antoine Ferchault de Réaumur (; ; 28 February 1683 – 17 October 1757) was a French entomologist and writer who contributed to many different fields, especially the study of insects. He introduced the Réaumur temperature scale. Life Réaumur was born in a prominent La Rochelle family and educated in Paris. He learned philosophy in the Jesuits' college at Poitiers, and in 1699 went to Bourges to study civil law and mathematics under the charge of an uncle, canon of La Sainte-Chapelle. In 1703 he went to Paris, where he continued the study of mathematics and physics. In 1708, at the age of 24, he was nominated by Pierre Varignon (who taught him mathematics) and elected a member of the Académie des Sciences.Egerton, F. N. 2006A History of the Ecological Sciences, Part 21: Réaumur and His History of Insects Bulletin of the Ecological Society of America 87(3):212–224.

Astronomer
An astronomer is a scientist in the field of astronomy who focuses on a specific question or field outside the scope of Earth. Astronomers 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 typically 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 Con ...

James Ferguson (Scottish Astronomer)
James Ferguson (25 April 1710 – 17 November 1776) was a Scottish astronomer. He is known as the inventor and improver of astronomical and other scientific apparatus, as a striking instance of self education and as an itinerant lecturer. Biography Ferguson was born near Rothiemay in Banffshire of humble parents. According to his autobiography, he learned to read by hearing his father teach his elder brother, and with the help of an old woman was able to read quite well before his father thought of teaching him. After his father taught him to write, he was sent at the age of seven for three months to the grammar school at Keith and that was all the formal education he ever received. His taste for mechanics was about this time accidentally awakened on seeing his father making use of a lever to raise a part of the roof of his house — an exhibition of strength which excited his wonder. In 1720 he was sent to a neighboring farm to keep sheep, where he amused himself b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Chemist
A chemist (from Greek ''chēm(ía)'' alchemy; replacing ''chymist'' from Medieval Latin ''alchemist'') is a graduated scientist trained in the study of chemistry, or an officially enrolled student in the field. Chemists study the composition of matter and its properties. Chemists carefully describe the properties they study in terms of quantities, with detail on the level of molecules and their component atoms. Chemists carefully measure substance proportions, chemical reaction rates, and other chemical properties. In Commonwealth English, pharmacists are often called chemists. Chemists use their knowledge to learn the composition and properties of unfamiliar substances, as well as to reproduce and synthesize large quantities of useful naturally occurring substances and create new artificial substances and useful processes. Chemists may specialize in any number of Chemistry#Subdisciplines, subdisciplines of chemistry. Materials science, Materials scientists and metallurgists sha ...

Scottish People
Scottish people or Scots (; ) are an ethnic group and nation native to Scotland. Historically, they emerged in the Scotland in the Early Middle Ages, early Middle Ages from an amalgamation of two Celtic peoples, the Picts and Gaels, who founded the Kingdom of Scotland (or ''Kingdom of Alba, Alba'') in the 9th century. In the following two centuries, Celtic-speaking Hen Ogledd, Cumbrians of Kingdom of Strathclyde, Strathclyde and Germanic-speaking Anglo-Saxons, Angles of Northumbria became part of Scotland. In the Scotland in the High Middle Ages, High Middle Ages, during the 12th-century Davidian Revolution, small numbers of Normans, Norman nobles migrated to the Lowlands. In the 13th century, the Norse-Gaels of the Kingdom of the Isles, Western Isles became part of Scotland, followed by the Norsemen, Norse of the Northern Isles in the 15th century.

William Cullen
William Cullen (; 15 April 17105 February 1790) was a British physician, chemist and agriculturalist from Hamilton, Scotland, who also served as a professor at the Edinburgh Medical School. Cullen was a central figure in the Scottish Enlightenment: He was David Hume's physician, and was friends with Joseph Black, Henry Home, Adam Ferguson, John Millar, and Adam Smith, among others. He was president of the Royal College of Physicians and Surgeons of Glasgow (1746–47), president of the Royal College of Physicians of Edinburgh (1773–1775) and first physician to the king in Scotland (1773–1790). He also assisted in obtaining a royal charter for the Philosophical Society of Edinburgh, resulting in the formation of the Royal Society of Edinburgh in 1783. Cullen was a beloved teacher, and many of his students became influential figures. He kept in contact with many of his students, including Benjamin Rush, a central figure in the founding of the United States of Americ ...

Equatorial Telescope
An equatorial mount is a mount for instruments that compensates for Earth's rotation by having one rotational axis, called ''polar axis'', parallel to the Earth's axis of rotation. This type of mount is used for astronomical telescopes and cameras. The advantage of an equatorial mount lies in its ability to allow the instrument attached to it to stay fixed on any celestial object with diurnal motion by driving one axis at a constant speed. Such an arrangement is called a ''sidereal drive'' or '' clock drive''. Equatorial mounts achieve this by aligning their rotational axis with the Earth, a process known as ''polar alignment''. Astronomical telescope mounts In astronomical telescope mounts, the equatorial axis (the ''right ascension'') is paired with a second perpendicular axis of motion (known as the ''declination''). The equatorial axis of the mount is often equipped with a motorized "'' clock drive''", that rotates that axis one revolution every 23 hours and 56 minutes ...

Philosophical Transactions Of The Royal Society Of London
''Philosophical Transactions of the Royal Society'' is a scientific journal published by the Royal Society. In its earliest days, it was a private venture of the Royal Society's secretary. It was established in 1665, making it the second journal in the world exclusively devoted to science, after the ''Journal des sçavans'', and therefore also the world's longest-running scientific journal. It became an official society publication in 1752. The use of the word ''philosophical'' in the title refers to natural philosophy, which was the equivalent of what would now be generally called ''science''. Current publication In 1887 the journal expanded and divided into two separate publications, one serving the physical sciences (''Philosophical Transactions of the Royal Society A: Mathematical, Physical and Engineering Sciences'') and the other focusing on the life sciences (''Philosophical Transactions of the Royal Society B: Biological Sciences''). Both journals now publish themed i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
