  • Chapter 1 the Biography of a Trafficking Material
    Trafficking Materials and Maria Rentetzi Gendered Experimental Practices Chapter 1 The Biography of a Trafficking Material In 1904, an article titled "Radium and Radioactivity" appeared in Century 1 Magazine, a monthly popular magazine published from 1881 to 1930. The article presents Marie Curie's personal account of the discovery of radium and radioactivity. In the article, Curie discusses in depth her arduous attempts to study the radiation of the compounds of uranium and that of known chemical elements, hoping to discover more which are endowed with atomic radioactivity. She revels that it was the chemists who supplied her with the materials she needed. "As I desired to make a very thorough investigation, I had resource to different chemists, who put at my disposal specimens—in some cases the only ones in existence—containing very rare elements." Her next step was to examine different minerals, especially the oxide of uranium 2 ore (pitchblende). To her great surprise, this specimen was found to be four times more active than oxide of uranium itself. The explanation was more than obvious. "The ore must contain a substance more radioactive than uranium and thorium, and this substance must necessarily be a chemical element as yet unknown."1 Her attempts to isolate the new element would lead Marie and Pierre Curie, who joined her research shortly after, to the discovery of both polonium and radium, to the Nobel Prize in Physics in 1903, and to a second Nobel Prize in 1911, this time in chemistry. This chapter attempts to present a cultural

It will continue to "ensure, so far as it is able, that assistance provided by it or at its request or under its super­ vision or control is not used in such a way as to further any military purpose". IN HONOUR OF MARIE SKLODOWSKA-CURIE This year marks the hundredth anniversary of the birth in Poland of Marie Sklodowska-Curie, originator of the word "radioactivity", whose early research in the subject has had far-reaching consequences for the nuclear sciences. The Government of Poland's arrangements for marking the occasion include an international symposium, restoration of her house in Warsaw, publications and films, and the Agency is happy to collaborate. This article from a distinguished Austrian scientist indicates how her work was carried out in an atmosphere of co-operation between scientists of many nations. By Dr. Berta Karlik (The author has been since 1945 Director of the Institute for Radium Research and Nuclear Physics, Austrian Academy of Sciences, where she succeeded Professor Stefan Meyer. A graduate of Vienna Uni­ versity and member of a number of learned societies, she has produced many scienti­ fic papers, including one published in 1944 dealing with the occurrence in nature of element 85, Astatine. This element was the last in the atomic table to be identified and occurs naturally only in minute quantities. It was first produced artificially by E.C.Segre, D.R.Corson and K.R.Mac- Kenzie in 1940 at the University of Cali­ fornia). The fact that the International Atomic Energy Agency has established its headquarters in Vienna prompts one to consider briefly, on the occasion of the 100th anniversary of Marie Curie's birth, the important part played by 18 Austria, and particularly by the Academy of Sciences in Vienna, in the dis­ coveries of this great scientist and in the further development of her work.

  • Karl Przibram: Radioactivity, Crystals, and Colors
    Phys. Perspect. 21 (2019) 163–193 Ó 2019 The Author(s) This article is an open access publication 1422-6944/19/030163-31 https://doi.org/10.1007/s00016-019-00242-z Physics in Perspective Karl Przibram: Radioactivity, Crystals, and Colors Wolfgang L. Reiter* Karl Przibram is one of the pioneers of early solid state physics in the field of the inter- dependence of coloration effects and luminescence in solids (crystals, minerals) induced by radiation. In 1921 Przibram discovered the effect of radio-photoluminescence, the light- stimulated phosphorescence in activated crystals induced by gamma rays. In 1926 Przibram was the first to use the term, Farbzentrum (color center, F-center), and in 1923 he advanced the view of atomic centers as carriers of coloration. Being a pupil of Ludwig Boltzmann and Franz S. Exner, he dedicated his early work to condensation and conductivity phenomena in gases and Brownian motion. Under the influence of Stefan Meyer, he began his lifelong interest in mineralogy, setting up his own research group at the Vienna Radium Institute, which pioneered investigations on thermoluminescence and gave a first description of glow curves. Being of Jewish descent, Przibram had to leave Austria after the Nazis took power; he found shelter in Belgium and returned to Austria in 1946 as professor for experimental physics at the University of Vienna. This paper is a first attempt to give an overview of the cultural and scientific background of Przibram’s life and science in context of the cultural and political developments from 1900 to 1950 in Austria. Key words: Biography; mineral physics; coloration effects and luminescence in solids; Ludwig Boltzmann; Franz S.

  • Curie Meitner Lamarr In
    CURIE_MEITNER_LAMARR_INDIVISIBLE The Research School of Physics & Engineering at The Australian National University together with the Austrian Embassy, Canberra, proudly presents Curie_Meitner_Lamarr_indivisible by the ‘portraittheater’ from Vienna, Austria. This highlights three outstanding women in the field of science and technology, whose achievements still affect our lives today. Their triumphs and struggles are brought to life in this performance illustrating their passion and ground- breaking research. Actress: Anita Zieher Director: Sandra Schüddekopf ________________________________________________________ The event is proudly sponsored by The Australian National University and the Austrian Embassy Canberra. Marie Curie The supreme principle is not to allow anything to get you down, not from people, nor from events. In 1867 on November 7th Marya Sklodowska was born in Warsaw. Her father worked as a mathematics and physics teacher and her mother taught at a private school. The family called her “Mania”. In 1883 she graduated from the Lyzeum with honors. Although forbidden in the Russian regime, she secretly learnt and read polish. Through bad investments the family lost nearly all their savings. In 1883 she took a job as governess to finance the medical education of her older sister in Paris. Unsalaried and in secret she read Polish literature to working women at the polish-national oriented “Free University” in Warsaw. In 1885 she worked as a tutor in the countryside for the Zorawski family in Szczuki. With the help of the eldest daughter she taught farmers’ children to read and write. She fell in love with the eldest son of the family, but their wedding plans were abandoned at his family’s insistence.

Alikhanyan National Laboratory of Armenia and Institute of Structure & Nuclear Astrophysics University of Notre Dame, Notre Dame, Indiana, USA High Precision Mass Measurements of Nuclei and the Neutron Star Merger The US science academies report on “Connecting Quarks to the Cosmos'' identified eleven of the most challenging open questions for all of physics in the 21st century. One of these eleven questions included the identification of the site(s) for the production of the heaviest elements found in nature: How were elements Fe to U made? Most of the elements above Fe in the periodic table are thought to have been produced by either the slow (s-process) or rapid (r-process) capture of neutrons in astrophysical environments. The s-process proceeds close to stability and astrophysical sites have been identified, while the r-process allows the production of nuclei much further from stability and potential sites remain mostly unresolved. The recent observation of gravitational waves from two neutron star mergers simultaneously with the spectroscopy indicated that rare earth elements were made in this so-called kilonova event. The questions remain, are there enough such mergers? Are mergers the only source of r-process elements ? This seminar will address the role of nuclear physics measurements, specifically the high precision measurement of nuclear masses and their role in understanding this potential site for the synthesis of the elements from Fe to U.

Though prepared to become a teacher of French at an Austrian highschool, Lise Meitner, daughter of a lawyer, could not help coming under the spell of physics. By lucky coincidence she followed courses dispensed by no one less than Ludwig Boltzmann, whose wit and humour proved contagious. After her PhD, under Franz Exner, she moved on, not to Paris to work with Marie Curie, but to Berlin, to consult with Max Planck on future contingencies.

Eduard Suess Carl Auer von Welsbach (1831 – 1914) (1858-1929) In 1904, the geologist Eduard Suess, then president of the Royal Academy of Sciences in Vienna, authorized the chemist, inventor and entrepreneur Auer von Welsbach to extract Radium from 10,000 kg of Uranium ore tailings from Joachimsthal in Bohemia (now Jachymov, Czech Republic) in a plant in Atzgersdorf near Vienna, where Auer von Welsbach normally produced gas incandescent light units. By 1908, ~3 g Radium had been extracted Already at that time the Academy gave 300 mg Ra ‘on loan’ to Ernest Rutherford Karl Kupelwieser (1841-1925) In 1908, Dr. Karl Kupelwieser, a lawer, industrialists, and philanthropist, donated half a million Crowns (~ 5 million Euros) to the Royal Academy of Sciences to build an “Institute for Radium Research” in Vienna.
