Royal Institution
The Royal Institution of Great Britain (often the Royal Institution, Ri or RI) is an organisation for scientific education and research, based in the City of Westminster. It was founded in 1799 by the leading British scientists of the age, including Henry Cavendish and its first president, George Finch. Its foundational principles were diffusing the knowledge of, and facilitating the general introduction of useful mechanical inventions and improvements, as well as enhancing the application of science to the common purposes of life (including through teaching, courses of philosophical lectures, and experiments). Much of the Institution's initial funding and the initial proposal for its founding were given by the Society for Bettering the Conditions and Improving the Comforts of the Poor, under the guidance of philanthropist Sir Thomas Bernard and American-born British scientist Sir Benjamin Thompson, Count Rumford. Since its founding it has been based at 21 Albemarle Stree ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Albemarle Street
Albemarle Street is a street in Mayfair in central London, off Piccadilly. It has historic associations with George Gordon Byron, 6th Baron Byron, Lord Byron, whose publisher John Murray (publishing house), John Murray was based here, and Oscar Wilde, a member of the Albemarle Club, where an insult he received led to his suing for libel and to his eventual imprisonment. It is also known for its art galleries and the Brown's Hotel is located at 33 Albemarle Street. History Albemarle Street was built by a syndicate of developers headed by Sir Thomas Bond. The syndicate purchased a Piccadilly mansion called Clarendon House from Christopher Monck, 2nd Duke of Albemarle in 1684, which had fallen into ruin due to neglect caused by the dissolute duke's spendthrift ways. It was sold for £20,000, a fifth less than the duke had paid for it only nine years previously despite the land values in the area increasing in the intervening period. The house was demolished and the syndicate p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
George III Of Great Britain
George III (George William Frederick; 4 June 173829 January 1820) was King of Great Britain and Ireland from 25 October 1760 until his death in 1820. The Acts of Union 1800 unified Great Britain and Ireland into the United Kingdom of Great Britain and Ireland, with George as its king. He was concurrently Duke and Prince-elector of Hanover in the Holy Roman Empire before becoming King of Hanover on 12 October 1814. He was the first monarch of the House of Hanover who was born in Great Britain, spoke English as his first language, and never visited Hanover. George was born during the reign of his paternal grandfather, King George II, as the first son of Frederick, Prince of Wales, and Princess Augusta of Saxe-Gotha. Following his father's death in 1751, Prince George became heir apparent and Prince of Wales. He succeeded to the throne on George II's death in 1760. The following year, he married Princess Charlotte of Mecklenburg-Strelitz, with whom he had 15 children. Geo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Max Perutz
Max Ferdinand Perutz (19 May 1914 – 6 February 2002) was an Austrian-born British molecular biologist, who shared the 1962 Nobel Prize for Chemistry with John Kendrew, for their studies of the structures of haemoglobin and myoglobin. He went on to win the Royal Medal of the Royal Society in 1971 and the Copley Medal in 1979. At Cambridge he founded and chaired (1962–79) The MRC Laboratory of Molecular Biology (LMB), fourteen of whose scientists have won Nobel Prizes. Early life and education Perutz was born in Vienna, the son of Adele "Dely" (Goldschmidt) and Hugo Perutz, a textile manufacturer. His parents were Jewish by ancestry, but had baptised Perutz in the Catholic religion. Although Perutz rejected religion and was an atheist in his later years, he was against offending others for their religious beliefs. His parents hoped that he would become a lawyer, but he became interested in chemistry while at school. Overcoming his parents' objections he enrolled as a chemi ...

X-ray Diffraction
X-ray diffraction is a generic term for phenomena associated with changes in the direction of X-ray beams due to interactions with the electrons around atoms. It occurs due to elastic scattering, when there is no change in the energy of the waves. The resulting map of the directions of the X-rays far from the sample is called a diffraction pattern. It is different from X-ray crystallography which exploits X-ray diffraction to determine the arrangement of atoms in materials, and also has other components such as ways to map from experimental diffraction measurements to the positions of atoms. This article provides an overview of X-ray diffraction, starting with the early #History, history of x-rays and the discovery that they have the right spacings to be diffracted by crystals. In many cases these diffraction patterns can be #Introduction to x-ray diffraction theory, Interpreted using a single scattering or kinematical theory with conservation of energy (#Ewald's sphere, wave vecto ...

Nobel Prize For Physics
The Nobel Prize in Physics () is an annual award given by the Royal Swedish Academy of Sciences for those who have made the most outstanding contributions to mankind in the field of physics. It is one of the five Nobel Prize, Nobel Prizes established by the will of Alfred Nobel in 1895 and awarded since 1901, the others being the Nobel Prize in Chemistry, Nobel Prize in Literature, Nobel Peace Prize, and Nobel Prize in Physiology or Medicine. Physics is traditionally the first award presented in the Nobel Prize ceremony. The prize consists of Nobel Prize medal, a medal along with a diploma and a certificate for the monetary award. The obverse, front side of the medal displays the same profile of Alfred Nobel depicted on the medals for Physics, Chemistry, and Literature. The first Nobel Prize in Physics was awarded to German physicist Wilhelm Röntgen in recognition of the extraordinary services he rendered by the discovery of X-rays. This award is administered by the Nobel Founda ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
William Lawrence Bragg
Sir William Lawrence Bragg (31 March 1890 – 1 July 1971) was an Australian-born British physicist who shared the 1915 Nobel Prize in Physics with his father William Henry Bragg "for their services in the analysis of crystal structure by means of X-rays", an important step in the development of X-ray crystallography. As of 2024, he is the youngest ever Nobel laureate in physics, or in any science category, having received the award at the age of 25. Bragg was the director of the Cavendish Laboratory, Cambridge, when James D. Watson and Francis Crick reported the discovery of the structure of DNA in February 1953. Education and early life Bragg was born in Adelaide, South Australia to William Henry Bragg (1862–1942), Elder Professor of Mathematics and Physics at the University of Adelaide, and Gwendoline (1869–1929), daughter of Charles Todd, government astronomer of South Australia.

William Henry Bragg
Sir William Henry Bragg (2 July 1862 – 12 March 1942) was an English physicist and X-ray crystallographer who uniquelyThis is still a unique accomplishment, because no other parent-child combination has yet shared a Nobel Prize (in any field). In several cases, a parent has won a Nobel Prize, and then years later, the child has won the Nobel Prize for separate research. An example of this is with Marie Curie and her daughter Irène Joliot-Curie, who are the only mother-daughter pair. Several father-son pairs have won two separate Nobel Prizes. shared a Nobel Prize with his son Lawrence Bragg – the 1915 Nobel Prize in Physics: "for their services in the analysis of crystal structure by means of X-rays". Biography Early years Bragg was born at Westward, near Wigton, Cumberland, England, the son of Robert John Bragg, a merchant marine officer and farmer, and his wife Mary née Wood, a clergyman's daughter. When Bragg was seven years old, his mother died, and he was rais ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
James Dewar
Sir James Dewar ( ; 20 September 1842 – 27 March 1923) was a Scottish chemist and physicist. He is best known for his invention of the vacuum flask, which he used in conjunction with research into the liquefaction of gases. He also studied atomic and molecular spectroscopy, working in these fields for more than 25 years. Dewar was nominated for the Nobel Prize 8 times — 5 times in Physics and 3 times in Chemistry — but he was never so honoured. Early life James Dewar was born in Kincardine, Perthshire (now in Fife) in 1842, the youngest of six boys of Ann Dewar and Thomas Dewar, a vintner. He was educated at Kincardine Parish School and then Dollar Academy. His parents died when he was 15. He attended the University of Edinburgh where he studied chemistry under Lyon Playfair (later Baron Playfair), becoming Playfair's personal assistant. Dewar also studied under August Kekulé at Ghent.

Potassium
Potassium is a chemical element; it has Symbol (chemistry), symbol K (from Neo-Latin ) and atomic number19. It is a silvery white metal that is soft enough to easily cut with a knife. Potassium metal reacts rapidly with atmospheric oxygen to form flaky white potassium peroxide in only seconds of exposure. It was first isolated from potash, the ashes of plants, from which its name derives. In the periodic table, potassium is one of the alkali metals, all of which have a single valence electron in the outer electron shell, which is easily removed to create cation, an ion with a positive charge (which combines with anions to form salts). In nature, potassium occurs only in ionic salts. Elemental potassium reacts vigorously with water, generating sufficient heat to ignite hydrogen emitted in the reaction, and burning with a lilac-flame color, colored flame. It is found dissolved in seawater (which is 0.04% potassium by weight), and occurs in many minerals such as orthoclase, a ...

Sodium
Sodium is a chemical element; it has Symbol (chemistry), symbol Na (from Neo-Latin ) and atomic number 11. It is a soft, silvery-white, highly reactive metal. Sodium is an alkali metal, being in group 1 element, group 1 of the periodic table. Its only stable isotope is 23Na. The free metal does not occur in nature and must be prepared from compounds. Sodium is the Abundance of elements in Earth's crust, sixth most abundant element in the Earth's crust and exists in numerous minerals such as feldspars, sodalite, and halite (NaCl). Many salts of sodium are highly water-soluble: sodium ions have been Leaching (chemistry), leached by the action of water from the Earth, Earth's minerals over eons, and thus sodium and chlorine are the most common dissolved elements by weight in the oceans. Sodium was first isolated by Humphry Davy in 1807 by the electrolysis of sodium hydroxide. Among many other useful sodium compounds, sodium hydroxide (lye) is used in Soap, soap manufac ...

William Thomas Brande
William Thomas Brande FRS FRSE (11 January 178811 February 1866) was an English chemist. Biography Brande was born in Arlington Street, London, England, the youngest son of six children to Augustus Everard Brande an apothecary, originally from Hanover in Germany. He was educated first in Kensington and then in Westminster. After leaving Westminster School, he was apprenticed, in 1802, to his brother, an apothecary, with the view of adopting the profession of medicine. He studied medicine at Great Windmill Street Medical School and at St George's Hospital, before being drawn to chemistry following a meeting with Humphry Davy. He then began to lecture in chemistry, based on a sound knowledge of which he acquired in his spare time. In 1811 he published the first of what were to be two very influential articles on the measurement of alcohol in fermented drinks, including wine, cider and ale. Until that point chemists had only been able to measure alcohol in distilled drinks (b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Humphry Davy
Sir Humphry Davy, 1st Baronet (17 December 177829 May 1829) was a British chemist and inventor who invented the Davy lamp and a very early form of arc lamp. He is also remembered for isolating, by using electricity, several Chemical element, elements for the first time: potassium and sodium in 1807 and calcium, strontium, barium, magnesium and boron the following year, as well as for discovering the elemental nature of chlorine and iodine. Davy also studied the forces involved in these separations, inventing the new field of electrochemistry. Davy is also credited with discovering clathrate hydrates. In 1799, he experimented with nitrous oxide and was astonished at how it made him laugh. He nicknamed it "laughing gas" and wrote about its potential as an Anesthesia, anaesthetic to relieve pain during surgery. Davy was a baronet, President of the Royal Society (PRS), Member of the Royal Irish Academy (MRIA), a founder member and Fellow of the Geological Society of London, and a ...
