Charles Glover Barkla, (1877- 1944) Brit fizikus, Nobel-díjas Cambridge-ben a Trinity és a Kings College-ban tanult. 1902: A Liverpooli Egyetem oktatója lett 1906: Barkla és C. A. Sadler röntgensugarak kal határozzák meg a szénatom elektronjainak a számát, amivel az Avogadro szám meghatározásának egy új módszerét is kidolgozzák. Barkla Nagyjából ugyanekkor polarizál ni is tudja a röntgensugarakat (olyan röntgenhullámokat válogatott ki, amelyek ugyanabban a síkban rezegnek), ezzel kimutatja, hogy a röntgensugarak transzverzális hullámok, azaz olyanok, mint a fény és más elektromágneses sugárzások. 1909: A Londoni Egyetemre megy át 1913: Az edinburgh-i Egyetemen a természetfilozófia professzora lesz 1911: Kísérletei alapján tisztázódik a röntgensugárzás két fajtája , a fékezési és a karakterisztikus. A fékezési sugárzás akkor keletkezik, amikor az elektron az atomba csapódva lefékezõdik. A karakterisztikus sugárzás nagy energiájú nyalábjai az adott antikatód anyagára jellemzõ frekvenciákat tartalmaznak, amelyek különbözõ sorozatokba rendeltek, és a K,L,M,O,P betûjelekkel nevezték el õket. A lítiumtól a neon i g csak a K sorozat fedezhetõ fel, a nagyobb rendszámú elemeknél jelentkeznek a sorozat késõbbi tagjai.

Soon after, Charles Glover Barkla discovered that each element has its own characteristic x-ray spectrum . He was awarded a Nobel Prize in physics for this discovery in 1917 . Sir William Henry Bragg and his son, Sir William Lawrence Bragg, were then able to experimentally prove that the discrete electron energy levels of an atom, an idea proposed by Niels Bohr, actually existed . They were awarded the Nobel Prize in physics for this in 1915 . After this groundwork in x-ray spectroscopy was established, Henry Moseley showed that each element’s characteristic x-ray energy spectrum followed the predictions of the Bohr atomic model . He developed a graphical method to display this data, now known as the Moseley diagram, which is displayed in Figure 1. This diagram was the first way that scientists were able to definitively establish the atomic numbers of the elements

These darklines, some narrow and some wide, are caused by the absorption of specific frequencies within the atmosphere of the earth or sun. Both colorful and informative, this chart makes an excellant teaching aid for any science classroom. This durable chart (seen above) is printed on heavy paper stock and is fitted with metal binding strips at top and bottom. The upper strip includes tabes suitable for wall haning. Chart dimention is 71cm x 28cm. each Chart - Laminated - Spectrum Analysis This chart shows the visible continuous spectrum of the sun and the emission or bright line spectra of ten relatively common elements. It provides an excellant beginning point to show the student the total individuality of the spectrum of each element. It also presents an opportunity to discuss the general relationship between the number of lines and the number of atomic shell electrons.

JUNE 7 - BIRTHS Virginia Apgar (EB) Born 7 June 1909; died 7 Aug 1974. American physician, anesthesiologist, and medical researcher who developed the Apgar Score System, a method of evaluating an infant shortly after birth to assess its well-being and to determine if any immediate medical intervention is required. Frederick Emmons Terman Born 7 June 1900; died 19 Dec 1982. American electrical engineer known for his contributions to electronics research and antiradar technology. He directed the Radio Research Laboratory at Harvard University during WW II. Allied forces benefitted from their inventions of jammers of enemy radar, chaff (aluminium strips) to mask targets by producing invalid reflections to enemy radar, and tunable receivers to detect radar signals. In his postwar work, Terman contributed to designing long-distance electrical transmission and resonant transmission lines Otto Heinrich Schindewolf Born 7 June 1896; died 10 June 1971. German paleontologist, known for his research on corals and cephalopods. He was an anti-Darwinist, who advocated a cataclysmic theory of evolution to explain the origin of the higher taxonomic categories. Studying different fossil species of coral and ammonites obtained from sequential geological strata, he concluded that the most recent taxonomic categories could not have arisen by slow, intermediate steps, generally thought to characterize evolution, but rather by large, single transformations. Though his views are not accepted by many biologists, particularly the population geneticists, who consider them too controversial, he has drawn attention to fundamental problems in evolution.

'All of us know something of that feeling of humility in the presence of greatness thing when we venture to ask a question of Nature herself. When we begin to venture to assemble the instruments, quite simple they may be, with which we hope to enquire into that which is yet unknown, we feel a certain shame at our temerity and perhaps would begin our work alone. 'It is the task of the researcher to describe what he observes so faithfully that his hearers also see the vision. He must serve them for their eyes, if they themselves are not trained to use them.' William Henry Bragg , the eldest of three boys, was born on 2 July 1862 in Cumberland, England. His father was a naval captain. In 1869 William Bragg's mother died; she was only thirty-six years old, and he was just seven. From this time on, he lived with his Uncle William, a chemist who ran a pharmacy, and was a major influence on the young William Bragg. William Bragg entered Cambridge University in 1881, following his obsession with mathematics. He tended to be reclusive, and called himself 'unadventuresome, shy and ignorant'. Despite his shyness, William Bragg loved his life at Cambridge University. After finishing his mathemetics studies, he turned his attention to physics and worked at the Cavendish Laboratory during part of 1885. At the end of this year, he applied for and was appointed to the position of Professor of Mathematics and Physics at the University of Adelaide, South Australia. Surprisingly, this application and appointment took place all within the space of just over one week! Three weeks later, William Bragg left for Australia.
