Newall.At its simplest, a mass spectrometer resembles a cathode ray tube, but its beam of charged particles is made up of positive ions rather than electrons. These ions are deflected from a straight line path by electric/magnetic fields. The amount of deflection depends on the ion’s mass (low masses are deflected more) and charge (high charges are deflected more).

Articles about T. Cavendish Laboratory. Available from <http://www.phy.cam.ac.uk/cavendish/history/>.T utilizó los rayos positivos o anódicos para separar átomos de distinta masa. Este método le posibilitó poder calcular la electricidad transportada por cada átomo y el número de moléculas por centímetro cúbico. A cathode ray tube, similar to that used by J. J. T. The air in the hollow glass tube is pumped out to create a vacuum. Electrons are produced at the cathode by a high voltage and travel through the vacuum, creating a green glow when they strike the glass at the end. Here a metal cross casts a shadow, establishing that the electrons are traveling in straight lines and cannot travel through metal. Image by Zátonyi Sándor.To explore the matter further he employed Schuster’s old technique of magnetic bending; for from the measured radius of curvature R of a beam of cathode rays deflected by a magnet of strength H one can infer a value for e/m, the ratio of the charge to the mass of the hypothetical cathode-ray particle (e/m = v/HR). Since the values for similar ratios, E/M, were known for ions produced in electrolysis, a comparison of e/m to E/M might provide a clue to the nature of the particle.3The last of T’s early research lines was the mathematical development of Maxwell’s electrodynamics. His first important results included the discovery of the so-called electromagnetic mass, or extra inertia, possessed by electrified bodies in virtue of their charge [2], and the calculation (in error by a factor of two) of the force–now known as the Lorentz force–exerted by a magnetic field on a moving electrified sphere “ibid.”. These results were not only important in themselves: they also marked or sparked the beginning of the rapid harvest of Maxwellian fruits by Fitzgerald, Heaviside, Lamb, Poynting, and T himself “eg., 6”.

Mesleğinin zirvesinde olduğu dönemde bile onursal paye, madalya veya ödül almak ya da Atlantik'i seve seve geçerek itibarlı konferanslarda konuşma yapmak dışında çok az seyahat etmişti.

The vortical mechanism for chemical bonding, he observed, works only when combining vortex rings have approximately the same size and velocity. Any disturbance in the medium, like the approach of another vortex atom, may alter the critical parameters and prevent linkage or disrupt unions. Now an electric field may be represented by a distribution of velocity in the medium; and the chemical decomposition it stimulates would be the immediate cause of the discharge. In this odd form T introduced an idea of the utmost importance for future work: that the gas discharge proceeds in analogy to electrolysis, by the disruption of chemical bonds. Initially, as was only natural, he regarded the particles into which the molecules separated under the influence of the field as “atoms.” Later researches (and, one presumes, a relaxation of his Maxwellian literalness) helped him to see the “atoms” first as “ions,” that is, charge carriers of atomic dimensions, and then as mixtures of ions and “bodies much smaller than atoms.”I. Most of T’s important papers were published in the Philosophical Magazine, which he took to be, and helped to make, the leading English journal for physics. His results would often be reprinted, more or less reworked, in books, two of which became fundamental texts in their fields [33, 50]. No full bibliography of his works exists; the best, that in the obituary notice by the 4th Baron Rayleigh (Obituary Notices of Fellows of the Royal Society, 3 [1941], 587–609), contains some 250 items and yet is quite incomplete.

J. T. In 1897 T discovered the electron and then went on to propose a model for the structure of the atom. His work also led to the invention of the mass spectrograph Three characteristics of these Applications deserve notice. For one, T shows himself a master of the literature, not excluding the pertinent papers of German experimentalists. He was to keep fully abreast of the journals (from which he sometimes took ideas whose origin he later forgot) until World War I [59:150–151, 219]. Second, the moderate phenomenology of the Applications, a work which eschews the specification of dynamical processes, recurs in much of T’s later work. His pioneering theory of the conduction of electricity in gases [24, 28], for example, merely assumes the existence of ions, and describes their behavior not in terms of the electrodynamics of their interactions, but via parameters–especially measures of mobility and recombination–to be fixed by experiment. Only later [e.g., 45] did he sketch a theory of the process of ionization.Physicists now had an incentive to investigate subatomic particles – particles smaller than the atom. They have done this ever since, trying to discover the building blocks that make up the building blocks that make up the building blocks that make up the building blocks… of matter.

J.J. mezun olduktan sonra, araştırmalarında kendisine yedi yıllık bir serbestlik sağlayacak ödül niteliğindeki kadro için şansını denemek üzere Trinity'de kaldı. Vereceği tezin konusunu, Owens College'da enerji üzerine dinlediği, ilham verici dersin etkisiyle kinetik enerjinin aktarımı olarak seçmişti. Bu tezi hazırlamak için üç yılı vardı ama J.J. tezini özenli ve yoğun bir çalışma sonucu, tam da ona özgü kendine güvenle hocasının tavsiyesine rağmen bir yıl içinde bitirip verdi. Tezi kabul edilmişti. Frtesi yıl vorteks halkalarının hareketi üzerine yazdığı bitirme teziyle Adams Ödülü'nü aldı ve Owens College'da yardımcı öğretim üyesi oldu. 1883'te de üniversitede hoca oldu.When T allowed his cathode rays to travel through air rather than the usual vacuum he was surprised at how far they could travel before they were stopped. This suggested to him that the particles within the cathode rays were many times smaller than scientists had estimated atoms to be. Synonyms for Joseph John T. English physicist who experimented with the conduction of electricity through gases and who discovered the electron and determined its charge and mass.. 1914'te Birinci Dünya Savaşfnın başlamasının ardından Royal Society'nin başkanlığına seçilen J.J. kamusal işlerle daha fazla uğraşmaya başladı. Britanyalı bilimciler savaşla ilgili işlerle ilgilendiklerinden normal bilimsel araştırmalar durma noktasına gelmişti. Ancak Britanya'nın uygulamalı bilimlerdeki geri kalmışlığının açığa çıkmasıyla Royal Society'nin başkanı olarak J.J. bir şeyler yapılması konusunda hükümeti ikna etme çabalarında öncü oldu. J.J., Alman asıllı üyelerin Royal Society'den çıkarılmasını isteyenlere muhalefet etti. 1918'de savaş bitince de Trinity'ye yönetici olarak atandı. Aynı zamanda, Cavendish'deki olanakları kullanabileceği kişisel bir araştırma kürsüsü karşılığında Cavendish'deki başkanlığından ve dolayısıyla laboratuvarın yönetiminden istifa etmesi istendi. Fizikle ilgilenmeye devam etti ama fiziğe daha fazla bir katkısı olmadı. Trinity'nin yöneticisi olarak okul komitelerinde etkili bir başkanlık yapıyor, öğrencilerle yakından ilgileniyor ve kendisi atletik bir kişi olmasa da özellikle öğrencileri spor yaparken izlemekten hoşlanıyordu.

T made this discovery when his research student Francis Aston fired ionized neon through a magnetic and electric field – i.e. he used a mass spectrometer – and observed two distinct deflections. T concluded that neon exists in two forms whose masses are different – i.e. isotopes. T, Sir Joseph John, 1856-1940, English physicist.

Also known as. English. Joseph T. Scottish geologist and explorer The English physicist Sir Joseph John T (1856-1940) is credited with the discovery of the electron. He read for the mathematical tripos, which at that time covered a wide range of pure mathematics as well as applications to many branches of physics. To “wrangle” successfully, that is, to place high on the tripos list, one needed great facility at computation and an ability to cope with the sort of models, or “physical analogies,” prized by the school of Kelvin, Stokes, and Maxwell. But one required neither knowledge nor experience of experimental physics; and so T, who prepared himself by following diligently the advice of his coach, E. J. Routh, did no more than put his foot into the Cavendish Laboratory, and never met Maxwell [58:95, 129], whose work was to inspire his own. He emerged second from the tripos of 1880, after Joseph Larmor, who, like himself, became a Cambridge professor.

T, physicist*Joseph T (explorer), African exploreree alsoJoseph Thompson.. Sir Joseph John J.J. T, OM, FRS (December 18, 1856 - August 30, 1940) was a British physicist and Nobel laureate, credited with the discovery of the electron, the isotope, and the invention of the mass spectrometer In discovering the electron, T also moved towards the invention of an immensely important new tool for chemical analysis – the mass spectrometer. J.J. T creó una primera aproximación al espectrómetro de masas. Esta herramienta le permitía al científico estudiar la relación masa/carga de los tubos de rayos catódicos, y medir cuánto se desvían por la influencia de un campo magnético y la cantidad de energía que llevan.

Este último se convertiría en un famoso científico, obteniendo en 1937, un Premio Nobel a la Física por sus trabajos con electrones.Ironically, T—great scientist and physics mentor—became a physicist by default. His father intended him to be an engineer, which in those days required an apprenticeship, but his family could not raise the necessary fee. Instead young T attended Owens College, Manchester, which had an excellent science faculty. He was then recommended to Trinity College, Cambridge, where he became a mathematical physicist. In 1884 he was named to the prestigious Cavendish Professorship of Experimental Physics at Cambridge, although he had personally done very little experimental work. Even though he was clumsy with his hands, he had a genius for designing apparatus and diagnosing its problems. He was a good lecturer, encouraged his students, and devoted considerable attention to the wider problems of science teaching at university and secondary levels.

Portrait of Joseph John T | Royal Society Picture

Based on his results, T produced his famous (but incorrect) plum pudding model of the atom. He pictured the atom as a uniformly positively charged ‘pudding’ within which the plums (electrons) orbited.In addition to making remarkable discoveries himself, T paved the way to greatness for a significant number of other scientists. A remarkable number of T’s research workers went on to win Nobel Prizes, including Charles T. R. Wilson, Charles Barkla, Ernest Rutherford, Francis Aston, Owen Richardson, William Henry Bragg, William Lawrence Bragg, and Max Born. "T, Joseph John ."

T came to physics for want of money to enter engineering. His father, a bookseller, sent him to Owens College to mark time until a leading engineer, to whom he was to be apprenticed, had an opening; but the father died before the vacancy occurred, and the family then could not afford the premium. With the help of small scholarships T continued to an engineering degree at Owens College, which had an excellent scientific faculty including Osborne Reynolds, Henry Roscoe, Balfour Stewart (under whom T did his first experimental work [1]), and Thomas Barker, the professor of mathematics, a former senior wrangler. On Barker’s advice T remained at Owens in order to work for an entrance scholarship in mathematics offered by Barker’s old college, Trinity (Cambridge). He won a minor scholarship and in 1876 went up to the university where he would spend the rest of his life [58:13–32].

Manchester, on dokuzuncu yüzyılın ortalarında aktif bir kültürel hayatın olduğu zengin bir şehirdi. Çok sayıda Kuzeyli işadamı sadık Protestanlardı. İnançları gereği gösterişten uzak yaşamlar sürüyorlar, sık sık kendilerine aşırı maliyet getiren sosyal iyileşme programları başlatmaları ve hayır işleri yapmaları gerekiyordu. Bu yardımsever adamların esas olarak ilgilendikleri alanlar, bilim, kamu sağlığı ve eğitimin geliştirilmesiydi. En önemli girişimlerden biri, tekstil ticareti yapan üniversite mezunu varlıklı biri tarafından 1851'de kurulan Owens College'tı. University of Manchester'ın öncülü olan Owens College'ın amacı Oxford ve Cambridge'den ziyade İskoç üniversitelerinin faaliyetleri temelinde bir eğitim modeli uygulamak, ticaret ve endüstriye atılma niyetindeki gençlere yardımcı olmaktı. Derslerde geleneksel konular temel alınmıştı: Latince ve Yunanca, matematik, doğa felsefesi, İngilizce, tarih, kimya, yabancı diller ve doğa tarihi. Diplomalar ikamet zorunluluğu gerektirmeyen University of London adına veriliyordu. Üniversitede hukuk, tıp ve teknoloji fakülteleri yoktu.Joseph John T, always known as "J. J.," was born in Manchester, England, on December 18, 1856. His fame derives primarily from his discovery of the electron in 1897. He studied physics and mathematics, first in Manchester, and in 1876 went to Trinity College, Cambridge University, and never left. He graduated in 1880 and in 1884 succeeded Lord Rayleigh as professor of physics and director of the Cavendish Laboratory. (When he retired from Cavendish in 1919 he passed the baton to Ernest Rutherford). T made Cambridge a world center for atomic physics. He won the Nobel Prize for physics in 1906 for his work on the electron, and seven of his research associates went on to win Nobel Prizes. The electron could almost be said to have been a family heirloom, as his son, George Paget T, won the Nobel Prize for physics (in 1937) for showing the wave nature of the electron.

  2. Electricity and Magnetism In addition to atoms, T began to take a serious interest in James Clerk Maxwell’s equations, which had revealed electricity and magnetism to be manifestations of a single force – the electromagnetic force – and had revealed light to be an electromagnetic wave.
  3. The electrolytic analogy suggested that important clues to the mechanics of gas discharge might come from studies of dielectric breakdown in poorly conducting liquids, or from decomposition of polyatomic gases by sparks. T and his students worked on the one [e.g., 11] and the other [10, the Bakerian lecture of 1887, continued in 16 and 18], and acquired many data without much advance in understanding. By the early 1890’s he had concluded that a study of the striated positive light was the most promising avenue to the understanding of the discharge. As for the cathode rays, which had seemed significant in the early 1880’s, they now appeared to him but a “local” and “secondary” matter [15:114–115].

"The Discovery of the Electron." American Institute of Physics. Available from <http://www.aip.org/history/electron/>.nació en Cheetam Hill, un distrito de Manchester, Inglaterra, el 18 de diciembre de 1856. También conocido como “J.J.” T, estudió ingeniería en Owens College, actualmente parte de la Universidad de Manchester, y luego, matemáticas en Cambridge.[23] “On the Leakage of Electricity Through Dielectrics Traversed by Röntgen Rays,” in PCPS, 9 (1896), 126–140, written with J. A. McClelland.After graduation T began working in the Cavendish Laboratory, which was under the direction of Lord Rayleigh. T's brilliance brought him membership in the Royal Society at 27 and his appointment as Rayleigh's successor at 28. He proved to be inspiring and effective both as a teacher and as a research director, and as time passed, students came to him from all over the world. He sometimes had as many as 40 to advise at once, and for the first quarter of the 20th century the Cavendish Laboratory, where T insisted that theory should be considered "a policy, not a creed, " was the world center for particle research.He also found the first evidence that stable elements can exist as isotopes and invented one of the most powerful tools in analytical chemistry – the mass spectrometer.

John Joseph T. John Joseph T. Par Personu. Vietas T’s discovery of the order of n did much more than recommend the cultivation of scattering theory. For one, it undermined the radiative stability of the atom and, by reducing the number of spectral emitters, made what Rayleigh called the “bog of spectroscopy” more mushy than ever. For another, it demonstrated that the chief part of the atomic mass must belong to the positive charge. T tended to ignore the first set of problems, although he once troubled to suggest how a single electron might, during its capture by an ionized atom, emit most or all of the line spectrum [39: 157–162]. It was different with the new-found substantiality of the plus charge, which no longer could be referred persuasively to a “property of the corpuscle.”

Joseph T. Apparently, this user prefers to keep an air of mystery about them Joseph John T, 18 aralık 1856'da Manchester şehrinin varoş semptlerinden olan Cheetham Hill'de doğdu. 1870'de lisans eğitimi için burs kazanarak girdiği Owens College'ın ardından 1876'da.. One is struck by the literalness with which T at first cultivated Maxwell’s theory. Not that he clung slavishly to his model, for his thorough report on electrical theories to the British Association for the Advancement of Science [8] points to obscurities in Maxwell’s formulation and discusses competing systems sympathetically. But he tried to remain true to what he considered the peculiar mark of Maxwell’s theory: the dielectric “displacement” D, whose divergence represented what other electricians called the electric fluid and whose time rate of change, even in the absence of matter, gave magnetic effects like those of an ordinary current. By obscuring the concept of charge, displacement caused much of the malaise felt by Continental readers of Maxwell, and it could lead even English ones astray. In his important paper of 1881 [2], T reached incorrect results by ascribing the magnetic field of a moving charged sphere solely to D outside it, thereby ignoring the most important factor, the convection of the charge [cf. 62:306–307;60:24, 55].Louis Agassiz | Maria Gaetana Agnesi | Al-BattaniAbu Nasr Al-Farabi | Alhazen | Jim Al-Khalili | Muhammad ibn Musa al-Khwarizmi | Mihailo Petrovic Alas | Angel Alcala | Salim Ali | Luis Alvarez | Andre Marie Ampère | Anaximander | Carl Anderson | Mary Anning | Virginia Apgar | Archimedes | Agnes Arber | Aristarchus | Aristotle | Svante Arrhenius | Oswald Avery | Amedeo Avogadro | Avicenna

T’s earliest effort at designing models was stimulated by the subject set for the Adams Prize of 1882, “a general investigation of the action upon each other of two closed vortices in a perfect incompressible fluid.” In his winning Treatise [5] T carried the matter further than required, to an application which, for him, gave it “the greater part of the interest it possesse[d]” [5:2], namely Kelvin’s theory of the vortex atom (1867). Here the atoms of a gas are represented as reentrant vortices in a frictionless fluid, rather like smoke rings in air; but the vortices, unlike the rings, are eternal, and therefore could reproduce the permanence of the Victorian atom.At least two other physicists–Emil Wiechert and Walther Kaufmann, both then beginning distinguished careers–had independently obtained the same sort of data about the rays, and had inferred the correct magnitude of e/m by deducing v from the energy which would be acquired by a particle falling through the full potential V of the tube (mv2/2=eV). The equation could scarcely be justified theoretically, as T liked to observe [e.g., 58:339]; but it gave the right order, and for this reason had been rejected by Schuster before the advent of Lenard. Despite their possessing most or all of the relevant data, neither Wiechert nor Kaufmann discovered the electron. Wiechert came closest: guided by the older Continental ideas about electricity [62:198 ff.], then recently revived by Lorentz, he identified the cathode-ray particle as a disembodied atom of electricity, a fundamental entity distinct from common matter. Kaufmann found nothing at all but an argument against “the hypothesis that assumes the cathode rays to be charged particles shot from the cathode.”4Cavendish Professor . In 1884 Lord Rayleigh, who had succeeded Maxwell, resigned the Cavendish Professorship of Experimental Physics. T had by then completed a few imperfect bits of laboratory work [cf. 44:80; 58:97], including a determination, at Rayleigh’s suggestion, of the ratio of the electrostatic to the electromagnetic unit of electricity “[4, corrected in 13]”. Rayleigh had intended to collaborate in this work which, apart from its imperfection, was typical of the Cavendish during his era; but T, unaware of many of the pitfalls, ran away with the project, published hastily, and gave his colleagues, including the Professor, to doubt that he had any future in experimental physics [59:18–20]. With these credits and his mathematics, he competed for the chair; much to his surprise [58:98], and to the great annoyance of some of his competitors, who included Fitzgerald, Glazebrook, Larmor, Reynolds, and Schuster, he was elected. It says much for the wisdom of the electors, among whom the ancient wranglers Stokes, William T, W. D. Niven, and George Darwin, one of the judges of T’s Adams Prize essay, were probably most influential.[27] “On the Charge of Electricity Carried by the Ions Produced by Röntgen-Rays,” in PM. 46 (1898), 528–545.Many scientists studied the electric discharge of a cathode ray tube. It was T's interpretation that was important. He took the deflection of the rays by the magnets and charged plates as evidence of "bodies much smaller than atoms." T calculated these bodies had a large charge-to-mass ratio and he estimated the value of the charge itself. In 1904, T proposed a model of the atom as a sphere of positive matter with electrons positioned based on electrostatic forces. So, he not only discovered the electron but determined it was a fundamental part of an atom. Sir Joseph John J. J. T (FRS*, OM**) (18 Aralık 1856 - 30 Ağustos 1940), Britanyalı fizikçi.
