Fine and clean. <br/><br/><em>First printing of this paper which is Hahn's Habilitation paper announcung his discovery of a new element in residues from a Ceylon mineral called Thorianite. He later showed that it is an intermediate disintegration product."Because the sample thorianite was small Ramsay proposed that Hahn confirm Marie Curie's determination of the atomic weight of radium by preparing it in some organic compounds thereby greatly increasing the total amount being examined and calculating the atomic weight from the measured molecular weights. Chance sometimes favors the unprepared mind and Hahn who familiarized himself with only the basic of radioactivity followed the prescribed separationss technique and found himself the discovere of a new radioelement: radiothorium. The explanation was that the material given him came from an ore which contained a large percentage of thorium in addition to the radium. Thus upon completion of the chemical procedure not all the activity was confined in the radium-containg fraction; indeed the nes subsyance in the remainder was several hundred thousand times more active than thorium and ultimately yielded the characteristic one.minute halflife of thorium emanation."DSB VI p. 15. - Weeks Discovery of the Elementsp. 308 ff. </em> unknown

It was Lockyer in the same year that named it 'helium' for Helios the Greek God of the Sun. Helium was not discovered on the earth before 1895 by William Ramsay and it was Crookes who established its identity with the helium Janssen and Lockyer observed in the spectrum of the sun."He Janssen met immortality by travelling to India in 1868 to study the total eclipse. It was then that he observed the helium line and forwarded the spectral data to ockyer. He also noted the size of the solar prominences. The day after the eclipse he attempted to take their spectra again and succeeded despite the absence of the obscuring moon. he then announced jubilantly that it was the day after the eclipse that was the real eclipse day for him. Lockyer also reported this method of studying prominences without an eclipse.Like Lockyer he lived to see his observation of the helium line vindicated by Ramsay's discovery of that element on earth."Asimov."This the discovery of helium lines in the sun by Lockyer was announced on the same day by the French astronomer Janssen who was in India observing a total eclipse. As a result the French government some ten years later struck a medallion showing the heads of both scientists.By that time the two men had made a much more dramatic discovery at the same time this time in cooperation. Janssen studying the spectrum ofthe sun during the eclipse had noted a fine line he did not recognize. he send a report on this to Lockyer an acknowledges expert on solar spectra. Lockyer compared the reported position of the line with lines of known elements concluding that it must belong to a yeat unknown element possibly not even existing on the earth. He named the element from the Greek word for the sun."Asimov.Parkinson "Breakthroughs" 1868 A. - The volume contains other notable papers by Dumas Berthelot et al. </em> hardcover

1904166196London: The Bruton Galleries Bond Street 1904-36. The blockbuster Discovery exhibition of 1904 The original visitor's book for one of the stellar red-carpet events of the season: the Bruton Galleries exhibition of artefacts and artwork from Scott's Discovery expedition a landmark in polar exploration. It includes the signatures of numerous crew members including Ernest H. Shackleton Edward A. Wilson Charles Royds Reginald Skelton and Ernest E. Joyce alongside Clements Markham and Llewellyn Longstaff a financial angel of the expedition. The exhibition which opened in November 1904 was curated by Clements Markham who had organized the expedition and launched Scott's polar career. It was remarkably extensive the catalogue listing 484 items including 150 photographs by Reginald Skelton 200 watercolours and drawings by Edward A. Wilson equipment from the expedition a model of the Discovery rations and the South Polar Times. The photographs and artwork constituted a visual record of Antarctic conditions and documented gruelling conditions bringing home "the scale magic and danger of Antarctica with a compelling immediacy" Merwe & Michell p. 66. The show proved extraordinarily popular with "Bruton Street and New Bond Street lined with motorcars and carriages" Huxley p. 141. "Persons of rank and fashion were marshalled into a long queue by a policeman. Society folk were not used to queues in those days and they protested that they had tickets; so had everyone the constable replied and kept them in line" Huxley p. 141. It fuelled the public's growing excitement about polar exploration: "an exhibit of Wilson's Antarctic art attracted over ten thousand viewers to London's prestigious Bruton Gallery. Advertisements in the gallery catalogue touted paints and binoculars used by the artist in the Antarctic" Larson p 159. The Discovery crew received an exuberant homecoming hailed for their "British grit" and Edward VII awarded each man the Antarctic medal. "Indeed for many Scott and his men became the national heroes that the Boer War had failed to supply. The explorers became celebrities. Crowds packed their public appearances" Larson p. 158. The leading actress Ellen Terry attended the event. She had been present when the expedition docked in Portsmouth later writing a postcard to Scott thanking him for letting her see the Discovery. The members of the Discovery expedition who have signed include Ernest H. Shackleton third lieutenant Edward A. Wilson assistant surgeon and artist Charles Royds first lieutenant Reginald Skelton chief engineer and photographer Ernest E. Joyce petty officer Arthur Henry Blissett steward Jacob Cross petty officer Hartley T. Ferrar geologist and Reginald C. Ford chief steward and stores officer. Curiously Scott is not among them. This might be a consequence of his resolve "to keep as quiet as possible" after the expedition Huxley p. 158. Three Shackleton family members attended: Ernest H. Shackleton's sisters Gladys and Helen besides Eileen Shackleton of Bushey. Other noted polar explorers feature among the visitors such as Robert Rudmose-Brown of the Scottish National Antarctic Expedition Scotia 1902-4 alongside its honorary secretary James G. Ferrier. Another notable voyager is Charles Ede the assistant surgeon on HMS Assistance on the British Franklin Search Expedition 1850-1 and a "Mrs. Reynolds" the great-niece of Franklin. The visitor's book serves as a record of an early 20th-century red carpet event and contains approximately 1000 signatures including the writer Walter Jerrold alongside the artists Felix Moscheles and Marietta Pallis. Robert Baden-Powell the founder of the Boy Scout movement also attended. Princess Beatrice and Maria Amelia Queen of Portugal likewise attended. Successive pages record visitors from Lancashire Yorkshire and Scotland. Moreover there are numerous admirals and military men together with a collector of Egyptian art. Two further sections in the book relate to miscellaneous exhibitions held in later years. Folio 283 x 245 mm. Contemporary dark red skiver by Jas.

Titlepage to vol. 12. <br/><br/><em>This is Ritter's first expositon of his discovery of ultraviolet light. It was announced the year before in a halfpage letter addressed to Gilbert's Annalen and printed in the Annalen. With that discovery it became clear that visible light represents no more than a fraction of a continous spectrum.A year earlier in 1800 William Herschel discovered infrared light. This was the first time that a form of light beyond visible light had been detected. After hearing about Herschel's discovery of an invisible form of light beyond the red portion of the spectrum Ritter decided to conduct experiments to determine if invisible light existed beyond the violet end of the spectrum as well. He had heard that blue light caused a greater reaction in silver chloride than red light did. Ritter decided to measure the rate at which silver chloride reacted to the different colors of light. He directed sunlight through a glass prism to create a spectrum. He then placed silver chloride in each color of the spectrum and found that it showed little change in the red part of the spectrum but darkened toward the violet end of the spectrum. Johann Ritter then decided to place silver chloride in the area just beyond the violet end of the spectrum in a region where no sunlight was visible. To his amazement this region showed the most intense reaction of all. This showed for the first time that an invisible form of light existed beyond the violet end of the visible spectrum. This new type of light which Ritter called Chemical Rays later became known as ultraviolet light or ultraviolet radiation the word ultra means beyond. </em> unknown

Curie and Joliot were awarded the Nobel Prize in Chemistry 1935 "in recognition of their synthesis of new radioactive elements"."Until this date 1934 atomic nuclei emitting radiation were found in nature: it was called the natural radioactivity. It had been known since Rutherford that this natural radioactivity changed a nucleus into an other one: for instance radium becomes finally lead after many radioactive decays. We could say that lead does not become gold but gold becomes lead! But. this change of matter was not under control. It was not possible to construct the desired chemical element as the alchemist dreamed. But Irene and Frederic Joliot-Curie made the dream become almost reality.""Another very important development in the early 1934 by the Joliot-Curies in connection with irradiation of aluminum by alpha particles. The two French scientists detected the production of the recently discovered positrons. . However they soon realized that the positron activity continued after the alpha source was removed and that they had in fact discovered positive beta radioactivity. The importance of the discovery of artificial radioactivity was immediately recognized and resulted in a Nobel Prize in chemistry to the Joliot-Curies in 1935. The new phenomenon immediately became widely employed in nuclear physics chemistry biology and medicine." Kragh Quantum Generations p. 187"These elegant experiments which provided the first chemical proof of induced transmutations and showed the possibility of artificially creating radioisotopes of known stable elements were repeated and extended in the major nuclear physics laboratories of various countries " DSB.Born on 12 September 1897 in Paris Irène Curie was the daughter of Pierre and Marie Curie. "During World War I she worked as a nurse helping her mother operate radiography equipment and then studied physics and mathematics at the Sorbonne gaining a doctorate for studying the range of alpha particles. She then went to work for her mother at the Radium Institute. There she met Frédéric Joliot whom she married in 1926. Frédéric Joliot was born on 19 March 1900 in Paris - He joined the Radium Institute in 1925 and obtained his PhD in 1930. Together the Joliot-Curies worked on radioactivity and the transmutation of the elements. Twice they just missed major discoveries: in 1932 when Chadwick beat them to the neutron and in 1933 when Anderson discovered the positron. However in 1934 whilst bombarding light elements with alpha particles the Joliot-Curies noticed that although proton production stopped when the alpha particle bombardment stopped another form of radiation continued. The alpha particles had produced an isotope of phosphorus not found in nature. This isotope was radioactive and was decaying through beta-decay" DSB. </em> unknown

Two days later he made a more remarkable discovery. It had occurred to him that perhaps thetransformation of amygdalin could be effected by the albumin in the almonds in a manner similar to the action of yeast in sugar.Wöhler suspected that the decomposition was an example of what Berzelius had recently defined as catalysis. Liebig and Wöhler then divided up the detailed examination of the properties and composition of amygdalin.
