London Borough Of Barnet
The London Borough of Barnet () is a suburban London borough in North London. The borough was formed in 1965 from parts of the ceremonial counties of Middlesex and Hertfordshire. It forms part of Outer London and is the largest London borough by population with 384,774 inhabitants, also making it the 13th largest district in England. The borough covers an area of , the fourth highest of the 32 London boroughs, and has a population density of 45.8 people per hectare, which ranks it 25th. Barnet borders the Hertfordshire district of Hertsmere to the north and five other London boroughs: Camden and Haringey to the southeast, Enfield to the east, as well as Harrow and Brent to the west of the ancient Watling Street (now the A5 road). The borough's major urban settlements are Hendon, Finchley, Golders Green, Friern Barnet, Chipping Barnet, Whetstone, and Edgware; there are also village settlements notably Totteridge and Arkley along with rural areas and countryside pa ...

Diffraction
Diffraction is defined as the interference or bending of waves around the corners of an obstacle or through an aperture into the region of geometrical shadow of the obstacle/aperture. The diffracting object or aperture effectively becomes a secondary source of the propagating wave. Italian scientist Francesco Maria Grimaldi coined the word ''diffraction'' and was the first to record accurate observations of the phenomenon in 1660. In classical physics, the diffraction phenomenon is described by the Huygens–Fresnel principle that treats each point in a propagating wavefront as a collection of individual spherical wavelets. The characteristic bending pattern is most pronounced when a wave from a coherent source (such as a laser) encounters a slit/aperture that is comparable in size to its wavelength, as shown in the inserted image. This is due to the addition, or interference, of different points on the wavefront (or, equivalently, each wavelet) that travel by paths of ...

Sloan Research Fellowship
The Sloan Research Fellowships are awarded annually by the Alfred P. Sloan Foundation since 1955 to "provide support and recognition to early-career scientists and scholars". This program is one of the oldest of its kind in the United States. Fellowships were initially awarded in physics, chemistry, and mathematics. Awards were later added in neuroscience (1972), economics (1980), computer science (1993), computational and evolutionary molecular biology (2002), and ocean sciences or earth systems sciences (2012). Winners of these two-year fellowships are awarded $75,000, which may be spent on any expense supporting their research. From 2012 through 2020, the foundation awarded 126 research fellowship each year; in 2021, 128 were awarded, and 118 were awarded in 2022. Eligibility and selection To be eligible, a candidate must hold a Ph.D. or equivalent degree and must be a member of the faculty of a college, university, or other degree-granting institution in the United Stat ...

Crystal Twinning
Crystal twinning occurs when two or more adjacent crystals of the same mineral are oriented so that they share some of the same crystal lattice points in a symmetrical manner. The result is an intergrowth of two separate crystals that are tightly bonded to each other. The surface along which the lattice points are shared in twinned crystals is called a composition surface or twin plane. Crystallographers classify twinned crystals by a number of twin laws. These twin laws are specific to the crystal structure. The type of twinning can be a diagnostic tool in mineral identification. Deformation twinning, in which twinning develops in a crystal in response to a shear stress, is an important mechanism for permanent shape changes in a crystal.Courtney, Thomas H. (2000) ''Mechanical Behavior of Materials'', 2nd ed. McGraw Hill. Definition Twinning is a form of symmetrical intergrowth between two or more adjacent crystals of the same mineral. It differs from the ordinary random ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Archibald Howie
Archibald "Archie" Howie (born 8 March 1934) is a British physicist and Emeritus Professor at the University of Cambridge, known for his pioneering work on the interpretation of transmission electron microscope images of crystals. Born in 1934, he attended Kirkcaldy High School and the University of Edinburgh. He received his PhD from the University of Cambridge, where he subsequently took up a permanent post. He has been a fellow of Churchill College since its foundation, and was President of its Senior Combination Room (SCR) until 2010. In 1965, with Hirsch, Whelan, Pashley and Nicholson, he published the seminal text ''Electron Microscopy of Thin Crystals''. He was elected to the Royal Society in 1978 and awarded their Royal Medal in 1999. In 1992 he was awarded the Guthrie Medal and Prize.

Cavendish Laboratory
The Cavendish Laboratory is the Department of Physics at the University of Cambridge, and is part of the School of Physical Sciences. The laboratory was opened in 1874 on the New Museums Site as a laboratory for experimental physics and is named after the British chemist and physicist Henry Cavendish. The laboratory has had a huge influence on research in the disciplines of physics and biology. The laboratory moved to its present site in West Cambridge in 1974. , 30 Cavendish researchers have won Nobel Prizes. Notable discoveries to have occurred at the Cavendish Laboratory include the discovery of the electron, neutron, and structure of DNA.

King's College, Cambridge
King's College is a constituent college of the University of Cambridge. Formally The King's College of Our Lady and Saint Nicholas in Cambridge, the college lies beside the River Cam and faces out onto King's Parade in the centre of the city. King's was founded in 1441 by King Henry VI soon after he had founded its sister institution at Eton College. Initially, King's accepted only students from Eton College. However, the king's plans for King's College were disrupted by the Wars of the Roses and the resultant scarcity of funds, and then his eventual deposition. Little progress was made on the project until 1508, when King Henry VII began to take an interest in the college, probably as a political move to legitimise his new position. The building of the college's chapel, begun in 1446, was finished in 1544 during the reign of Henry VIII. King's College Chapel is regarded as one of the finest examples of late English Gothic architecture. It has the world's largest fan vau ...

British Chess Championship
The British Chess Championships are organised by the English Chess Federation. The main tournament incorporates the British Championship, the English Chess Championships and the British Women's Chess Championship so it is possible, although it has never happened, for one player to win all three titles in the same competition. The English Women's Chess Championship was also incorporated into this event but did not take place in 2015 and was held as a separate competition in 2016. Since 1923 there have been sections for juniors, and since 1982 there has been an over-sixty championship. The championship venue usually changes every year and has been held in different locations in England, Scotland, Wales and once on the Isle of Man. The championship was originally open to citizens of any Commonwealth country and has previously been won by Mir Sultan Khan (India) and Abe Yanofsky (Canada). After the Indian R. B.
