Camp Century: The Incredible Story of How US Army Engineers Built an All-American, Nuclear-Powered City under Greenland’s Icecap

Located on the beeline between the two nuclear superpowers, Greenland took on vital strategic importance during the early phases of the Cold War. As part of its polar strategy, the United States undertook the construction of several bases in Greenland. Camp Century, known as ‘City under the Ice’, was an experimental-military American city built entirely inside the ice sheet in 1959-60. A 225-person, nuclear-powered army base, Century was the precursor for a much larger installation of intercontinental ballistic missiles (which never materialized), but was also used to disseminate popular images of techno-scientific control, nuclear containment, and American values. In popular books and films, “the city under the ice” was depicted as an outstanding example of man’s never-ceasing quest for knowledge, as the epic conquest of the harsh Arctic environment by US Army engineers, as an Arctic sword and shield against the Soviet aggressor, and as a friendly collaboration between the US and Denmark. In the end, however, Camp Century had to be abandoned much earlier than originally planned due to the glaciological forces of the moving ice sheet which crushed the tunnels, but also due to changes in the high politics of the Cold War and the political difficulties underscoring nuclear installations on Danish territory.

Fysisk Auditorium Har du også set et af de mange youtube-klip fra den 15. februar, hvor en meteor ubemærket sneg sig ind gennem Jordens atmosfære og eksploderede over Rusland? Eksplosionen satte gang i en chokbølge, som bl.a. fik en masse vinduer til at sprænge. Hvordan kan en chokbølge sprænge vinduer, og hvorfor eksploderede meteoren overhovedet?]]> Institut for Fysik og Astronomi Medarbejdere Offentligheden / Pressen lie@phys.au.dk Mon, 13 May 2013 15:20:00 +0200 Specialeforsvar - Anders A.

Sorte huller er et af Universets mest eksotiske fænomener, hvor den almindelige tyngdekraft er så voldsom, at den overvinder alle andre naturkræfter. Selv ikke lys kan undslippe fra et sort hul. I foredraget her vil jeg delvist snakke om, hvad vi allerede ved om sorte huller, hvilket inkluderer nye opdagelser af fx rotation af sorte huller og skyggen af det sorte hul i Mælkevejens centrum. Desuden vil jeg snakke en del om, hvad vi godt kunne tænke os at vide om sorte huller, som er et særdeles aktivt forskningsområde. Fx kunne vi godt tænke os at vide, hvordan gigantiske sorte huller opstår i det tidlige Univers, og hvorfor der findes både små og store sorte huller.]]> Institut for Fysik og Astronomi Offentligheden / Pressen Medarbejdere lie@phys.au.dk Tue, 21 May 2013 13:30:00 +0200 CSS Colloquium - Bo Poulsen: Environmental history http://phys.au.dk/aktuelt/nyhed/artikel/css-colloquium-bo-poulsen-environmental-history/ Formal and informal maritime empires – Danish marine science in the North Atlantic, c.... Formal and informal maritime empires – Danish marine science in the North Atlantic, c. 1900-1930. Bo Poulsen, Aalborg University Abstract  The concept of ‘Big Science’ is normally associated with the Manhattan Project and later initiatives, where governments, military forces, capitalist enterprises and scientists join hands in solving big societal issues together. This paper contends that the specific character of ocean explorations such as the huge costs of equipping vessels, manning them often for years of travels and handling the findings of explorations makes the concept of Big Science just as relevant for marine science also prior to WWII. In Denmark, a small power by European standards such a case of big science came about in the wake of the 20th century when Danish oceanography took to the deep sea. The personification of this was the Danish oceanographer Johannes Schmidt, the foremost fundraiser in Danish marine science in the first third of the 20th century. He was particularly apt at raising funds for deep sea explorations in the Atlantic, and crowned his achievements by successfully launching the world’s first circumnavigation with a distinct biogeographic purpose in 1928-30. The scientific legacy of these explorations amounts to discovering the breeding places of the Atlantic eel and later eels in the Pacific and Indian Oceans. Perhaps less spectacular but similarly path breaking was the marking experiments conducted over several decades to map the migration patterns of cod around Iceland. These expeditions, launched in Denmark unfolded as interplay between scientific strategies, colonial desires and changing natural resource availability in the Atlantic Ocean. In the cold waters around Iceland and Greenland there was a clear incentive to enhance knowledge on the emerging fisheries for cod and halibut for both direct fisheries gains and also in order to keep Norwegian geopolitical and fisheries resource driven interests at bay. In the Danish West Indies, the picture is less clear with regards the prospects of deep sea explorations creating immediate economic gains for local fisheries. Here, the overall Danish effort in oceanography should rather be seen as a way of unfolding an informal colonial empire through ocean sciences in a time when the Danish political colonial presence was folding.]]> Center for Videnskabsstudier Institut for Fysik og Astronomi Medarbejdere Studerende Offentligheden / Pressen trinebm@phys.au.dk Thu, 25 Apr 2013 15:51:00 +0200 Studenterkollokvium - Jakob Fester: 'Flydende Krystaller' http://phys.au.dk/aktuelt/nyhed/artikel/studenterkollokvium-jakob-fester-flydende-krystaller/ Flydende Krystaller Jakob Fester Vejleder: Nikolaj Zinner Torsdag den 30. maj kl. 14.15Fysisk...

Fysisk Auditorium I skolen lærer vi fra barnsben, at stof på jorden eksisterer i tre tilstandsformer: Fast stof, væske og gas. Der findes imidlertid en tilstand, de flydende krystaller, som ikke har naturlig plads i nogen af de tre kategorier, og som siden opdagelsen i 1888 har givet anledning til stor disput, undren og fascination. Hvordan kan noget være væske og krystal på én og samme tid? Hvordan beskrives dette fænomen fra en fysikers synsvinkel, og kan de flydende krystaller bruges til noget?]]> Institut for Fysik og Astronomi Medarbejdere Offentligheden / Pressen lie@phys.au.dk Fri, 17 May 2013 15:40:00 +0200 CSS Colloquium - Jens Fog Jensen: The Cold War: Facilities and histories from Greenland http://phys.au.dk/aktuelt/nyhed/artikel/css-colloquium-jens-fog-jensen-the-cold-war-facilities-and-histories-from-greenland/ The Cold War: Faciliteis and histories from Greenland Jens Fog Jensen, National Museum of...
