    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.

  • 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.

  • 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).

    Astronomy Cast Episode 207 Lyman Spitzer _____________________________________________________________________ Fraser: Astronomy Cast Episode 207 for Monday November 15, 2010, Lyman Spitzer. Welcome to Astronomy Cast, our weekly facts-based journey through the cosmos, where we help you understand not only what we know, but how we know what we know. My name is Fraser Cain, I'm the publisher of Universe Today, and with me is Dr. Pamela Gay, a professor at Southern Illinois University Edwardsville. Hi, Pamela, how are you doing? Pamela: I’m doing well. How are you doing, Fraser? Fraser: Good... how is your spare bedroom doing? Pamela: My spare bedroom is less overwhelmingly filled with things, but a new shipment is coming soon so please order more t-shirts... and we have skinny-people ones, too! Fraser: Great! So as we mentioned in the last show, we’ve got t-shirts, CDs, posters, all kinds of cool Astronomy Cast related stuff available. You just go to astrogear.org and see what we have on offer... and, yeah, you can buy it and clear out Pamela’s spare bedroom. Pamela: And I have to congratulate our audience because you guys are overwhelmingly thin! It was the most surreal discovery. Smalls and mediums sold out first and that was awesome and odd... Fraser: Lots of kids, too... that’s great. Pamela: Yeah. Fraser: Alright, well time for another action-packed double episode of Astronomy Cast. This week we focus on Lyman Spitzer, a theoretical physicist and astronomer who worked on star formation and plasma physics, and of course this will lead us into next week’s episode where we talk about the mission that bears his name, the Spitzer Space Telescope.
