The Nobel Prize in Physics and Lise Meitner
The Nobel Prize in Physics and Lise Meitner Ringvorlesung Zum Gedenken an Lise Meitner 2018/19 FU, Berlin, 4 February 2019 Karl Grandin, KVA – CVH “The women who were swindled out of the Nobel Prize” Questions • Is Lise Meitner forgotten? • Why did she chose Sweden? • No support in Sweden? • Was she counteracted by Manne Siegbahn? • Why did she not get the Nobel Prize in 1945 (1946, 1947)? • What happened then? Lise Meitner to Margarethe Bohr 25/11-1945 ”Du weisst ja, dass ich immer das Gefühl habe, das ich mit meiner ganzen Art nicht nach Schweden passe und ich habe auch noch keinen schwedischen Physiker getroffen”. Eva von Bahr and Lise Meitner in Berlin Eva von Bahr at Uppsala Physics institute Oskar Klein and Niels Bohr Atomic bombs over Hiroshima 6 August and over Nagasaki 9 August 1945 The Research institute for experimental physics of the Swedish Academy of Sciences, 1937– Manne Siegbahn Eva von Bahr-Bergius to Carl Wilhelm Oseen 31/1-1939 ”It doesn't seem possible to get any [assistant] now and Lise sounds rather unhappy. She says, she feels like a charlatan, who receives money [from the Nobel Committee 5,400 SEK + Eva vB-B], although she cannot accomplish much, and her life seems to her completely pointless. […] If she for the past two years had not been so unaccustomed to simpler technical work such as glass blowing, soldering etc. that she now cannot cope with such.” Carl Wilhelm Oseenen to Eva von Bahr-BergiusBahr 2/2-1939 ”Is it true what L.M. says, that it is an assistant she needs? Isn't it rather so, that what she needs is a - even with regard to staff - fully equipped institute, as whose brain she could be? The quote that you mentioned, seems to me, to point quite firmly in this direction. -
A Conceptual Framework and Its Application for Exploring Undergraduate Physics Students’ Identity Formation in Relation to Laboratory Work
The gendered doing of physics: A conceptual framework and its application for exploring undergraduate physics students’ identity formation in relation to laboratory work Anna T. Danielsson January 2007 Supervisor: Professor Cedric Linder Dissertation for the degree of Licentiate of Philosophy in Physics with Specialization in Physics Education Uppsala University, 2007 Abstract In this licentiate thesis I explore undergraduate physics students’ experiences of doing laboratory work in physics and, in particular, how this relates to the gendering of physics in relation to their formation of physicist identities. I outline a conceptual framework for exploring the gendered nature of learn- ing physics in the laboratory setting, and in this framework situated cogni- tion and post-structural gender theory are merged together. This allows me to analyze gender as an active process and to relate the dynamics of this process to the emerging physicist identities of the students. Thus, my con- ceptual framework allows for an analysis of the gendered learning experi- ences in physics that goes well beyond the usual ‘women-friendly’ teaching approaches. The conceptual framework has been developed ‘in conversation’ with an empirical study, where thirteen undergraduate physics students were interviewed about their experiences of learning from and doing laboratory work. I found these students to be constituting their physicist identities in relation both to different forms of ‘physicist masculinities’ and to what they characterized as ‘normal femininity’. The results, which are described in- depth in the thesis, are given and illustrated both in terms of the conceptual framing and descriptions taken from the interviews. Further, the results show the importance for teachers to deepen their understanding of students’ iden- tity formation in order to improve the students’ learning experiences in phys- ics, in the student laboratory as well as beyond it. -

The work was carried out in the dark, often to the accompaniment of Rutherford singing „Onward Christian Soldiers“. Rutherford had already proposed the neutron in 1920 in his Bakerian Lecture at the Royal Society. He talked about a “neutral doublet” (at that time considered a proton and electron) that could be difficult to detect and move easily through matter.

Paris 194, 273 (1932) When the radiation was passed through wax the ionisation increased! This increase was due to knock-on protons.

Moreover, the radiation also passed through lead This experiment was first performed in 1930 by Walter Bothe and Herbet Becker at U. -

A Fateful Year for a Physicist
FLASHBACK_Nuclear Fission A fateful year for a physicist For Lise Meitner, 1938 is something like a turning point in her life. She flees the Nazis and goes to Sweden, where she tries to establish herself as a scientist and finds the solution to a problem that Otto Hahn told her about in a letter. As a result, the former researcher at the Kaiser Wilhelm Institute for Chemistry becomes one of the co-discoverers of nuclear fission. TEXT SUSANNE KIEWITZ July 1938. Lise Meitner flees from Germany, her adopted country The scientific community tries to support Lise Meitner as best since 1907. After the annexation of her native country of Austria, it can, but ultimately with little success. As the best option of- she is at grave risk of falling victim to the anti-Semitic persecu- fered is a temporary job at the Nobel Institute in Stockholm, she tion in the Third Reich. At the urging of friends and colleagues – decides to go to Sweden. Yet the disappointment is great. “At most notably Otto Hahn – Meitner finally decided with a heavy the Institute, I have a workroom which is also my study and ex- heart to emigrate to Sweden. For her, it is the end of an era.

He has been labeled both warm and cold, friendly and condescending, affable as well as hurtful. Learning Sanskrit and cultivating the air of an aesthete, as a young professor he stretched the bounds of the scientist’s persona. Yet in the space of a decade, the otherworldly theorist was transformed into a political insider par excellence. His fellow scientists remembered him as a visionary and capable leader at Los Alamos, while his security hearing brought to light foolish mistakes in judgment and human relationships. -

Nobel Prize Awards in Radiochemistry
Radiochim. Acta 100, 509–521 (2012) / DOI 10.1524/ract.2012.1953 © by Oldenbourg Wissenschaftsverlag, München Nobel Prize awards in Radiochemistry By J.-P. Adloff∗ University of Strasbourg, 63 Rue Saint Urbain, 67100 Strasbourg, France Dedicated to the memory of late Karl H. Lieser, Gerhard L. Stöcklin and Alfred P. Wolf with whom the author shared the editorial work of Radiochimica Acta from 1977 to 1995 (Received October 10, 2011; accepted in revised form January 19, 2012) (Published online March 26, 2012) Nobel Prize / Chemistry / Physics Summary. In 1996 the Editors of Radiochimica Acta brought out a special volume of the journal to celebrate the hundredth anniversary of the discovery of radioactivity [1]. On the occasion of the 50th anniversary of Radiochimica Acta, which follows closely upon the centenary of Marie Curie’s second Nobel Prize in 1911, the author has the privilege to informally review “Radiochemistry and Nobel Prize Awards”, including discoveries of radioelements and new fields in chemistry based on radiochemical methods. 1.

Stuewer In late December 1938 Lise Meitner met her nephew Otto Robert Frisch in Kun- gälv, north of Gøteborg, Sweden, to spend the Christmas holidays with Swedish friends. They had not planned to meet in that unlikely place; both were victims of Nazi persecution: Frisch had been dismissed from his position in Hamburg after the promulgation of the Nazi Civil Service Law on 7 April 1933, and after a year in London he found a haven in the fall of 1934 in Niels Bohr’s Institute for Theoretical Physics in Copenhagen (Frisch 1979a; 1979b, 41–108; Peierls 1981, 285–290).
