The Royal Society and Science in the Twentieth Century A conference organised by the Royal Society Centre for the History of Science   22-23 April 2010 The Royal Society, 6-9 Carlton House Terrace, London   As part of our 350th anniversary celebrations in 2010, the Royal Society will hold an international conference on the history of science in the twentieth century. We are therefore issuing a call for papers on topics in twentieth century science. Broad areas of interest include (but are not limited to): astronomy and space exploration; science and war; scientific networks; medical research; women in science; scientific instruments and experimental equipment; the role of laboratory technicians; academies and international collaborations; and public understanding of science.   It is hoped that papers will reflect on the role of the Royal Society in the development of science in the twentieth century, through grant support, science policy, the work of individual Fellows, or in other ways. Papers making use of the Society’s archives will be particularly welcome. Selected papers will be published in a special 2010 issue of the Society’s journal Notes and Records of the Royal Society. It is therefore expected that a full draft of the paper will be made available to organisers before the conference.   Proposals for 20 minute papers are invited; they should include a title and abstract of approximately 250 words, and should be submitted to Felicity Henderson ([email protected]) by Friday 30 January 2009.
