Science
Science is a systematic endeavor that builds and organizes knowledge in the form of testable explanations and predictions about the universe. Science may be as old as the human species, and some of the earliest archeological evidence for scientific reasoning is tens of thousands of years old. The earliest written records in the history of science come from Ancient Egypt and Mesopotamia in around 3000 to 1200 BCE. Their contributions to mathematics, astronomy, and medicine entered and shaped Greek natural philosophy of classical antiquity, whereby formal attempts were made to provide explanations of events in the physical world based on natural causes. After the fall of the Western Roman Empire, knowledge of Greek conceptions of the world deteriorated in Western Europe during the early centuries (400 to 1000 CE) of the Middle Ages, but was preserved in the Muslim world during the Islamic Golden Age and later by the efforts of Byzantine Greek scholars who brought Greek ...

George Julius Poulett Scrope
George Julius Poulett Scrope FRS (10 March 1797 – 19 January 1876) was an English geologist and political economist as well as a Member of Parliament and magistrate for Stroud in Gloucestershire. While an undergraduate at Cambridge, through the influence of Edward Clarke and Adam Sedgwick he became interested in mineralogy and geology. During the winter of 1816–1817 he was at Naples, and was so keenly interested in Vesuvius that he renewed his studies of the volcano in 1818; and in the following year visited Etna and the Lipari Islands. In 1821 he married the daughter and heiress of William Scrope of Castle Combe, Wiltshire, and assumed her name; and he entered the House of Commons of the United Kingdom in 1833 as MP for Stroud, retaining his seat until 1868. Meanwhile he began to study the volcanic regions of central France in 1821, and visited the Eifel district in 1823. In 1825 he published ''Considerations on Volcanos'', leading to the establishment of a new the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Greenhouse Effect
The greenhouse effect is a process that occurs when energy from a planet's host star goes through the planet's atmosphere and heats the planet's surface, but greenhouse gases in the atmosphere prevent some of the heat from returning directly to space, resulting in a warmer planet. Earth's natural greenhouse effect makes life as we know it possible and carbon dioxide plays a significant role in providing for the relatively high temperature on Earth. The greenhouse effect is a process by which thermal radiation from a planetary atmosphere warms the planet's surface beyond the temperature it would have in the absence of its atmosphere.A concise description of the greenhouse effect is given in the ''Intergovernmental Panel on Climate Change Fourth Assessment Report,'' "What is the Greenhouse Effect?FAQ 1.3 – AR4 WGI Chapter 1: Historical Overview of Climate Change Science, IPCC Fourth Assessment Report, Chapter 1, p. 115: "To balance the absorbed incoming olarenergy, the Earth m ...

Joseph Fourier
Jean-Baptiste Joseph Fourier (; ; 21 March 1768 – 16 May 1830) was a French people, French mathematician and physicist born in Auxerre and best known for initiating the investigation of Fourier series, which eventually developed into Fourier analysis and harmonic analysis, and their applications to problems of heat transfer and vibrations. The Fourier transform and Thermal conduction#Fourier.27s law, Fourier's law of conduction are also named in his honour. Fourier is also generally credited with the discovery of the greenhouse effect. Biography Fourier was born at Auxerre (now in the Yonne département of France), the son of a tailor. He was orphaned at the age of nine. Fourier was recommended to the Bishop of Auxerre and, through this introduction, he was educated by the Benedictine Order of the Convent of St. Mark. The commissions in the scientific corps of the army were reserved for those of good birth, and being thus ineligible, he accepted a military lectureship on mathema ...

Brownian Motion
Brownian motion, or pedesis (from grc, πήδησις "leaping"), is the random motion of particles suspended in a medium (a liquid or a gas). This pattern of motion typically consists of random fluctuations in a particle's position inside a fluid sub-domain, followed by a relocation to another sub-domain. Each relocation is followed by more fluctuations within the new closed volume. This pattern describes a fluid at thermal equilibrium, defined by a given temperature. Within such a fluid, there exists no preferential direction of flow (as in transport phenomena). More specifically, the fluid's overall linear and angular momenta remain null over time. The kinetic energies of the molecular Brownian motions, together with those of molecular rotations and vibrations, sum up to the caloric component of a fluid's internal energy (the equipartition theorem). This motion is named after the botanist Robert Brown, who first described the phenomenon in 1827, while looking throu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Robert Brown (Scottish Botanist From Montrose)
Robert Brown (21 December 1773 – 10 June 1858) was a Scottish botanist and paleobotanist who made important contributions to botany largely through his pioneering use of the microscope. His contributions include one of the earliest detailed descriptions of the cell nucleus and cytoplasmic streaming; the observation of Brownian motion; early work on plant pollination and fertilisation, including being the first to recognise the fundamental difference between gymnosperms and angiosperms; and some of the earliest studies in palynology. He also made numerous contributions to plant taxonomy, notably erecting a number of plant families that are still accepted today; and numerous Australian plant genera and species, the fruit of his exploration of that continent with Matthew Flinders. Early life Robert Brown was born in Montrose, Angus, Montrose on 21 December 1773, in a house that existed on the site where Montrose Library currently stands. He was the son of James Brown (Scottis ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bright's Disease
Bright's disease is a historical classification of kidney diseases that are described in modern medicine as acute or chronic nephritis. It was characterized by swelling and the presence of albumin in the urine, and was frequently accompanied by high blood pressure and heart disease. Signs and symptoms The symptoms and signs of Bright's disease were first described in 1827 by the English physician Richard Bright, after whom the disease was named. In his ''Reports of Medical Cases'', he described 25 cases of dropsy ( edema) which he attributed to kidney disease. Symptoms and signs included: inflammation of serous membranes, hemorrhages, apoplexy, convulsions, blindness and coma. Many of these cases were found to have albumin in their urine (detected by the spoon and candle-heat coagulation), and showed striking morbid changes of the kidneys at autopsy. The triad of dropsy, albumin in the urine, and kidney disease came to be regarded as characteristic of Bright's disease. Sub ...

Richard Bright (physician)
Richard Bright (28 September 1789 – 16 December 1858) was an English physician and early pioneer in the research of kidney disease. He is particularly known for his description of Bright's disease. Biography He was born in Bristol, Gloucestershire, the third son of Sarah and Richard Bright Sr., a wealthy merchant and banker. Bright Sr. shared his interest in science with his son, encouraging him to consider it as a career. In 1808, Bright Jr. joined the University of Edinburgh to study philosophy, economics and mathematics, but switched to medicine the following year. In 1810, he accompanied Sir George Mackenzie on a summer expedition to Iceland where he conducted naturalist studies. Bright then continued his medical studies at Guy's Hospital in London and in September 1813 returned to Edinburgh to be granted his medical doctorate. His thesis was ''De erysipelate contagioso'' (''On contagious erysipelas''). During the 1820s and 1830s Bright again worked at Guy's Hospital, ...

Robert Adams (physician)
Robert Adams (1791 – 13 January 1875) was an Irish surgeon and was three times President of the Royal College of Surgeons in Ireland (RCSI), in 1840, 1860 and 1867. Early life and education Adams was born in 1791 in Dublin, Ireland and studied at Trinity College, Dublin between 1810 and 1814. He received his B.A. in 1814. He began his medical training under William Hartigan and George Stewart, leading Dublin surgeons. He was elected a fellow of the RCSI in 1818 and then went abroad to complete his medical and surgical training. Adams did not take the M.B. degree until 1842. In that year he became an M.D., and in 1861 received the newly-instituted qualification of Master in Surgery. The greater part of Adams' anatomical studies were undertaken in the RCSI under Abraham Colles. In 1816, he obtained the Letters Testimonial, and on 2 November 1818, he was promoted to Membership of the College. He was elected surgeon to the Jervis Street Hospital and the Richmond Hospital.
