Hitler and Heisenberg
The Wall Street Journal December 27-28, 2014 Book Review “Serving the Reich” by Philip Ball, Chicago, $30, 303 pages Hitler and Heisenberg Werner Heisenberg thought that once Germany had won, the ‘good Germans’ would get rid of the Nazis. Fizzing The museum inside the former basement tavern where in early 1945 German scientists built a small nuclear reactor. Associated Press by Jeremy Bernstein The German scientists who remained in Germany throughout the Nazi period can be divided into three main groups. At one end were the anti-Nazis—people who not only despised the regime but tried to do something about it. They were very few. Two that come to mind were Fritz Strassmann and Max von Laue. Strassmann was a radiochemist—a specialist in radioactive materials—who was blacklisted from university jobs by the Society of German Chemists in 1933 for his anti-Nazi views. He was fortunate to get a half-pay job at the Kaiser Wilhelm Institute for Chemistry, which got some of its funding from industry. He and his wife (they had a 3-year-old son) hid a Jewish friend in their apartment for months. With the radiochemist Otto Hahn, he performed the 1938 experiment in which fission was observed for the first time. Von Laue won the Nobel Prize in physics in 1914. Soon after Einstein published his 1905 paper on relativity, von Laue went to Switzerland to see him. They remained friends for life. Under the Nazis, Einstein’s work was denounced as “Jewish science.” When a number of von Laue’s colleagues agreed to use relativity but attribute it to some Aryan, he refused. -
What Use Is Chemistry?
2 Inspirational chemistry What use is chemistry? Index 1.1 1 sheet This activity is based on a Sunday Times article by Sir Harry Kroto, a Nobel prize winning chemist who discovered a new allotrope of carbon – buckminsterfullerene or ‘bucky balls’. The article appeared on November 28, 2004 and is reproduced overleaf as a background for teachers. The aim is to introduce students to the scope of modern chemistry and the impact that it has on their lives, even in areas that they may not think of as related to chemistry. An alternative exercise for more able students would be to research what was used before chemical scientists had produced a particular new product or material (eg silk or wool stockings before nylon, leather footballs before synthetics, grated carbolic soap before shampoo) and then to write about the difference it would make to their lives if they did not have the modern product. Students will need: ■ Plenty of old magazines and catalogues (Argos catalogues are good as virtually everything in them would not exist without modern chemistry) ■ Large sheets of sugar paper ■ Glue and scissors. It works well if students produce the poster in groups, but then do the written work by themselves. The activity could be set for homework. Inspirational chemistry 3 What use is chemistry?

The Lock-And-Key Analogy in 20Th Century Biochemistry
From: Rebecca Mertens The Construction of Analogy-Based Research Programs The Lock-and-Key Analogy in 20th Century Biochemistry April 2019, 224 p., pb., ill. 34,99 € (DE), 978-3-8376-4442-5 E-Book: PDF: 34,99 € (DE), ISBN 978-3-8394-4442-9 When the German chemist Emil Fischer presented his lock-and-key hypothesis in 1899, his analogy to describe the molecular relationship between enzymes and substrates quickly gained vast influence and provided future generations of scientists with a tool to investigate the relation between chemical structure and biological specificity. Rebecca Mertens explains the appeal of the lock-and-key analogy by its role in model building and in the construction of long-term, cross-generational research programs. She argues that a crucial feature of these research programs, namely ascertaining the continuity of core ideas and concepts, is provided by a certain way of analogy-based modelling. Rebecca Mertens (PhD), born in 1984, is a postdoctoral researcher in the history and philosophy of science at the University of Bielefeld, Germany. She works on the role of analogies, models and forms of comparison in the history of molecular genetics and is a member of the collaborative research program "Practices of ComparisonÚ Ordering and Changing the World". During her graduate and doctoral studies, she was a visiting scholar at the École Normale Supérieure in Paris and a visiting graduate fellow at the Minnesota Center for Philosophy of Science.

F Otto Warburgs Tagebuchnotizen von Februar–April 1945 Kärin Nickelsen Warburg’s diary notes February–April 1945 Personal notes in the form of a diary, written by the German cell biologist Otto Warburg in the weeks before the collapse of Germany’s Third Reich (Feb.-April 1945), were found at the end of one of his labo- ratory notebooks, which are preserved in the Archives of the Berlin-Brandenburg Academy of Sciences and Humanities. These notes are unique in form and content: there seem to be no other surviving diary notes of this type. Written from a very personal perspective, they provide a detailed account of how Warburg experienced local events in this decisive and turbulent period. Furthermore, they clearly demonstrate Warburg’s embittered attitude towards some of his long-standing collaborators, whom he suspected of having denounced him to the Nazi authorities. In this paper, Warburg’s notes are fully transcribed and integrated into the historical context.

Biographical Memoir COPYRIGHT 1997 NATIONAL ACADEMIES PRESS WASHINGTON D.C. LINUS CARL PAULING February 28, 1901–August 19, 1994 BY JACK D. DUNITZ INUS CARL PAULING was born in Portland, Oregon, on LFebruary 28, 1901, and died at his ranch at Big Sur, California, on August 19, 1994. In 1922 he married Ava Helen Miller (died 1981), who bore him four children: Linus Carl, Peter Jeffress, Linda Helen (Kamb), and Edward Crellin. Pauling is widely considered the greatest chemist of this century. Most scientists create a niche for themselves, an area where they feel secure, but Pauling had an enormously wide range of scientific interests: quantum mechanics, crys- tallography, mineralogy, structural chemistry, anesthesia, immunology, medicine, evolution. In all these fields and especially in the border regions between them, he saw where the problems lay, and, backed by his speedy assimilation of the essential facts and by his prodigious memory, he made distinctive and decisive contributions. He is best known, perhaps, for his insights into chemical bonding, for the discovery of the principal elements of protein secondary structure, the alpha-helix and the beta-sheet, and for the first identification of a molecular disease (sickle-cell ane- mia), but there are a multitude of other important contri- This biographical memoir was prepared for publication by both The Royal Society of London and the National Academy of Sciences of the United States of America. -
Basic Research in the Max Planck Society Science Policy in the Federal Republic of Germany, 1945–1970
Chapter 5 Basic Research in the Max Planck Society Science Policy in the Federal Republic of Germany, 1945–1970 Carola Sachse ላሌ The Max Planck Society for the Advancement of Science (MPG, Max- Planck-Gesellschaft zur Förderung der Wissenschaften) is commonly consid- ered a stronghold of basic research in the German research landscape. When it was reestablished in 1948 in the Western zones of occupation, the society adopted the defi ning part of its predecessor’s name, the Kaiser Wilhelm So- ciety for the Advancement of Science (KWG, Kaiser-Wilhelm-Gesellschaft zur Förderung der Wissenschaften), which had been founded in 1911. In contrast to its organizational counterpart, the Fraunhofer Society for the Ad- vancement of Applied Research (Fraunhofer-Gesellschaft zur Förderung der angewandten Forschung), whose distinctive purpose has been incorporated into its name since its foundation in 1949 (Trischler and vom Bruch 1999), the MPG did not include the term “basic research” in its full name, nor does the term appear in any of its statutes of the last one hundred years. The offi - cial documents of the MPG instead refer to “scientifi c research” in the broad German sense of wissenschaftliche Forschung and combine it in varying formu- lations with the terms “freedom” and “independence.”1 Both of these terms are cornerstones in what became known as Harnack- Prinzip (Harnack principle). Named after Adolf von Harnack, the initiator and fi rst and longtime serving president of the KWG, this principle included two main aspects: fi rst, institutes should be founded only if a man was avail- able (women were not considered) for the post of managing director “who has This open access library edition is supported by the University of Bonn. -
