The Periodic Table Of Videos
''Periodic Videos'' (also known as ''The Periodic Table of Videos'') is a video project and YouTube channel on chemistry. It consists of a series of videos about chemical elements and the periodic table, with additional videos on other topics in chemistry and related fields. They are published on YouTube and produced by Brady Haran, a former BBC video journalist, mainly featuring Sir Martyn Poliakoff, Peter Licence, Stephen Liddle, Debbie Kays, Neil Barnes, Sam Tang, and other scientists at the University of Nottingham. Development The project began recording on 9 June 2008 and the initial videos were completed on 17 July 2008. The collection includes videos, each just a few minutes long, for all 118 known elements with a video for each element, as well as many additional supplemental chemistry videos. The 118 element videos and introduction videos were all shot unscripted in June and July 2008. Since the initial videos were completed in 2008 the team has been refining and up ...

Sir Martyn Poliakoff
Sir Martyn Poliakoff (born 16 December 1947) is a British chemist, working on gaining insights into fundamental chemistry, and on developing environmentally acceptable processes and materials. The core themes of his work are supercritical fluids, infrared spectroscopy and lasers. He is a research professor in chemistry at the University of Nottingham. His group comprises several members of staff, postdoctoral research fellows, postgraduate students and overseas visitors.

He has a younger brother, the screenwriter and director Stephen Poliakoff. His p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Albert Einstein
Albert Einstein ( ; ; 14 March 1879 – 18 April 1955) was a German-born theoretical physicist, widely acknowledged to be one of the greatest and most influential physicists of all time. Einstein is best known for developing the theory of relativity, but he also made important contributions to the development of the theory of quantum mechanics. Relativity and quantum mechanics are the two pillars of modern physics. His mass–energy equivalence formula , which arises from relativity theory, has been dubbed "the world's most famous equation". His work is also known for its influence on the philosophy of science. He received the 1921 Nobel Prize in Physics "for his services to theoretical physics, and especially for his discovery of the law of the photoelectric effect", a pivotal step in the development of quantum theory. His intellectual achievements and originality resulted in "Einstein" becoming synonymous with "genius". In 1905, a year sometimes described as his ' ...

Nottingham
Nottingham ( , locally ) is a city and unitary authority area in Nottinghamshire, East Midlands, England. It is located north-west of London, south-east of Sheffield and north-east of Birmingham. Nottingham has links to the legend of Robin Hood and to the lace-making, bicycle and tobacco industries. The city is also the county town of Nottinghamshire and the settlement was granted its city charter in 1897, as part of Queen Victoria's Diamond Jubilee celebrations. Nottingham is a tourist destination; in 2018, the city received the second-highest number of overnight visitors in the Midlands and the highest number in the East Midlands. In 2020, Nottingham had an estimated population of 330,000. The wider conurbation, which includes many of the city's suburbs, has a population of 768,638. It is the largest urban area in the East Midlands and the second-largest in the Midlands. Its Functional Urban Area, the largest in the East Midlands, has a population of 919,484. The popula ...

Broadway Media Centre
Broadway Cinema is an independent cinema in the city of Nottingham, England in the United Kingdom. It is located in the Hockley area. In 2009, it was rated as one of the best cinemas in the world by Total Film magazine. History The site now occupied by the cinema began its life as the Broad Street Wesleyan Church, which was built in 1839 by the architect S. S. Rawlinson. This church is reputedly where the founder of the Salvation Army, William Booth, was converted. Since the 1960s, the site has housed the Co-operative Education Centre, the Nottingham Film Society, City Lights Cinema and, since 1982, the Broadway Cinema. In 1993, the cinema was the venue for the UK premiere of Quentin Tarantino's ''Pulp Fiction'', showing it immediately after its screening at the Cannes Film Festival. For many years, film director Shane Meadows worked out of the venue; he still uses it as a base for press interviews. Likewise, the filmmaker Jeanie Finlay has edited most of her films on the ...

Uranium
Uranium is a chemical element with the symbol U and atomic number 92. It is a silvery-grey metal in the actinide series of the periodic table. A uranium atom has 92 protons and 92 electrons, of which 6 are valence electrons. Uranium is weakly radioactive because all isotopes of uranium are unstable; the half-lives of its naturally occurring isotopes range between 159,200 years and 4.5 billion years. The most common isotopes in natural uranium are uranium-238 (which has 146 neutrons and accounts for over 99% of uranium on Earth) and uranium-235 (which has 143 neutrons). Uranium has the highest atomic weight of the primordially occurring elements. Its density is about 70% higher than that of lead, and slightly lower than that of gold or tungsten. It occurs naturally in low concentrations of a few parts per million in soil, rock and water, and is commercially extracted from uranium-bearing minerals such as uraninite. In nature, uranium is found as uranium-238 (99. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Potassium
Potassium is the chemical element with the symbol K (from Neo-Latin ''kalium'') and atomic number19. Potassium is a silvery-white metal that is soft enough to be cut with a knife with little force. 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, that is easily removed to create an ion with a positive charge – a cation, that combines with anions to form salts. Potassium in nature 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- colored flame. It is found dissolved in sea water (which is 0.04% potassium by weight), and occurs in many minerals such as orthocl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sodium
Sodium is a chemical element with the symbol Na (from Latin ''natrium'') and atomic number 11. It is a soft, silvery-white, highly reactive metal. Sodium is an alkali metal, being in 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 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 leached by the action of water from the 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 manufacture, and sodium chloride (edible salt) is a de-icing agent and a nutrient for animals inc ...

Royal Society Of London Michael Faraday Prize
The Royal Society of London Michael Faraday Prize is awarded for "excellence in communicating science to UK audiences". Named after Michael Faraday, the medal itself is made of silver gilt, and is accompanied by a purse of £2500. Background The prize was first awarded in 1986 to Charles Taylor for "his outstanding presentations of physics and applications of physics, aimed at audiences from six-year-old primary school children to adults". It is awarded annually and unlike other Royal Society awards such as the Hughes Medal, it has been presented every year since its inception. The winner is required to present a lecture as part of the Society's annual programme of public events, which is usually held in January of the following year; during the lecture, the President of the Royal Society awards the medal. Unlike other prizes awarded by the society, the committee has not always publicly provided a rationale. This has occurred five times—in 2004 to Martin Rees, in 2006 to Richa ...
