View metadata, citation and similar papers at core.ac.uk brought to you by CORE provided by CERN Document Server Marietta Blau's Work After World War II Arnold Perlmutter Department of Physics University of Miami Coral Gables, Florida 33124 completed, October 27, 2000 This paper has been translated into German and will be included, in a somewhat altered form, in a book Sterne der Zertrummerung, Marietta Blau, Wegbereiterin der Moderne Teilchenphysik, Brigitte Strohmaier and Robert Rosner, eds., Boehlau Verlag, Wien. 1 A. Introduction While it is clear that the seminal work of Dr. Marietta Blau was done in the 1920’s and especially in the 1930’s, it is also evident that her separation from the great research centers from 1938 to 1944 had a devastating effect on her productivity. It was during this period that Cecil F. Powell, at Bristol University, made use of Blau’s earlier tutelage on the preparation and analysis of photographic emulsions. According to Blau’s conversations with me (much later), she consulted with Ilford in the 1930’s to improve emulsion sensitivity and uniformity, and presumably had also imparted crucial lore of the technique to Powell. C.F. Powell, who had been a student of C.T.R. Wilson, had employed cloud chambers in a wide variety of studies in vulcanology, mechanical engineering, and nuclear physics. In 1938 and 1939 Powell’s experimental efforts turned to the use of photographic emulsions to investigate neutron interactions, and then to nuclear reactions1. With the coming of the war and then the British nuclear atomic bomb project, Powell established a formidable laboratory and collaboration for the analysis of emulsions and for their improvement by Ilford and Kodak. -

ATOMIC HERITAGE FOUNDATION Preserving & Interpreting Manhattan Project History & Legacy preserving history ANNUAL REPORT 2013 WHY WE SHOULD PRESERVE THE MANHATTAN PROJECT “The factories and bombs that Manhattan Project scientists, engineers, and workers built were physical objects that depended for their operation on physics, chemistry, metallurgy, and other nat- ural sciences, but their social reality - their meaning, if you will - was human, social, political....We preserve what we value of the physical past because it specifically embodies our social past....When we lose parts of our physical past, we lose parts of our common social past as well.” “The new knowledge of nuclear energy has undoubtedly limited national sovereignty and scaled down the destructiveness of war. If that’s not a good enough reason to work for and contribute to the Manhattan Project’s historic preservation, what would be? It’s certainly good enough for me.” ~Richard Rhodes, “Why We Should Preserve the Manhattan Project,” Bulletin of the Atomic Scientists, May/June 2006 Photographs clockwise from top: J.

Chapter 6 the Aftermath of the Cambridge-Vienna Controversy: Radioactivity and Politics in Vienna in the 1930S
Trafficking Materials and Maria Rentetzi Gendered Experimental Practices Chapter 6 The Aftermath of the Cambridge-Vienna Controversy: Radioactivity and Politics in Vienna in the 1930s Consequences of the Cambridge-Vienna episode ranged from the entrance of other 1 research centers into the field as the study of the atomic nucleus became a promising area of scientific investigation to the development of new experimental methods. As Jeff Hughes describes, three key groups turned to the study of atomic nucleus. Gerhard Hoffman and his student Heinz Pose studied artificial disintegration at the Physics Institute of the University of Halle using a polonium source sent by Meyer.1 In Paris, Maurice de Broglie turned his well-equipped laboratory for x-ray research into a center for radioactivity studies and Madame Curie started to accumulate polonium for research on artificial disintegration. The need to replace the scintillation counters with a more reliable technique also 2 led to the extensive use of the cloud chamber in Cambridge.2 Simultaneously, the development of electric counting methods for measuring alpha particles in Rutherford's laboratory secured quantitative investigations and prompted Stetter and Schmidt from the Vienna Institute to focus on the valve amplifier technique.3 Essential for the work in both the Cambridge and the Vienna laboratories was the use of polonium as a strong source of alpha particles for those methods as an alternative to the scintillation technique. Besides serving as a place for scientific production, the laboratory was definitely 3 also a space for work where tasks were labeled as skilled and unskilled and positions were divided to those paid monthly and those supported by grant money or by research fellowships. -
70Th Anniversary of the Manhattan Project Atomic Heritage Foundation
Atomic Heritage Foundation presents 70th Anniversary of the Manhattan Project June 2 and 3, 2015 Carnegie Institution for Science 1530 P Street, NW Washington, DC 20005 Visit our merchandise tables to purchase books, posters, and hats! Manhattan Project 70th Anniversary Manhattan Project veterans Lawrence S. O’Rourke (left) and William E. Tewes (right) with his future wife, Olive. The Atomic Heritage Foundation is proud to host events commemorating the 70th Anniversary of the Manhattan Project. It took more than half a million people to build the world’s first atomic bombs; we are honored to welcome more than a dozen men and women who participated in that astonishing effort. The 70th Anniversary Reunion on June 2 will be an opportunity for vet- erans and family members to share their memories and catch up with old friends. Veterans from Los Alamos, Oak Ridge, Hanford, Chicago and other locations will discuss how each site contributed to the Manhattan Project in its own unique way. The 70th Anniversary commemoration will continue on June 3 with a day- long symposium, which will feature a discussion of the new Manhattan Project National Historical Park. We have assembled a first-class roster of Manhattan Project veterans and experts who will discuss topics ranging from innovation to women in science to atomic spies and more. We hope you enjoy the events! Cynthia C. Kelly President, Atomic Heritage Foundation Atomic Heritage Foundation The Atomic Heritage Foundation (AHF), founded by Cynthia C. Kelly in 2002, is a nonprofit organization in Washington, DC, dedicated to the preservation and interpretation of the Manhattan Project and its legacy. -
From the Discovery of Radioactivity to the First Accelerator Experiments
Chapter 2 From the Discovery of Radioactivity to the First Accelerator Experiments Michael Walter 2.1 Introduction The article reviews the historical phases of cosmic ray research from the very be- ginning around 1900 until the 1940s, when the first particle accelerators replaced cosmic particles as a source for elementary particle interactions. Contrary to the discovery of X-rays or the ionising α-, β- and γ -rays, it was an arduous path to the definite acceptance of the new radiation. The development in the years before the discovery is described in Sect. 2.2. The following section deals with the work of Victor F. Hess, especially with the detection of extraterrestrial radiation in 1912 and the years until the final acceptance by the scientific community. In Sect. 2.4 the study of the properties of cosmic rays is discussed. Innovative detectors and meth- ods like the cloud chamber, the Geiger–Müller counter and the coincidence circuit brought new stimuli. The origin of cosmic rays was and is still an unsolved ques- tion. The different hypotheses of the early time are summarised in Sect. 2.5.Inthe 1930s a scientific success story started which nobody of the first protagonists might have imagined. The discovery of the positron by C.D. Anderson was the birth of elementary particle physics. The 15 years until a new era started in 1947 with first accelerator experiments at the Berkeley synchro-cyclotron are described in Sect. 2.6. It is obvious that this article can only cover the main steps of the historical de- velopment. An excellent description of the research on the “Höhenstrahlung” in the years between 1900 and 1936 was given by Miehlnickel (1938). -
