Patrick Moore, Arthur C. Clarke and ‘British Outer Space’ in the mid 20th century

This article seeks to explore a notion of 'British outer space' in the mid 20th century with reference to the British Interplanetary Society and the works of Patrick Moore and Arthur C. Clarke. Geographies of outer space have been examined following early work by Denis Cosgrove on the Apollo space photographs. Cosgrove's work has encouraged a growing body of work that seeks to examine both the 'Earth from space' perspective as well as its reciprocal, 'space from Earth'. This article aligns itself with the latter viewpoint, in attempting to define a national culture of 'British outer space'. This is found to have an important connection with the British Interplanetary Society, founded in 1933 near Liverpool, which went on to influence the works of Patrick Moore, who edited the magazine Spaceflight and presented the television programme The Sky at Night, and Arthur C. Clarke, who became known as a science fiction writer through his early novels in the 1950s. The themes of audience participation and human destiny in outer space are examined in a close reading of these two case studies, and further engagement with cultures of outer space in geography is encouraged. © The Author(s) 2012.

Voyage(s) to Sarajevo: Jean-Luc Godard and the Image of War

This essay discusses Jean-Luc Godard’s artistic response to the Bosnian War (1992-95), and its representations in the Western mass media. For Godard, the reluctance of Europe’s advanced liberal democracies to intervene meaningfully in Bosnia – their insistence that 'humanitarianism' rather than protective intervention was the order of the day – was tantamount to supporting Serbian fascism, and – a fortiori – regressing to a policy of appeasement reminiscent of the days of the Munich Agreement. Although Godard's stance set him against some of his former compatriots on the left, speculating on his ideological motivations is beside the point. Rather, it is is in his filmmaking, in his vision of cinema, and how it relates to other histories of the image, that Godard’s sensibility can be most keenly felt and understood. As the essay points out, even his recent contribution to Jean-Michel Frodon's compilation film, Bridges of Sarajevo/Les ponts de Sarajevo (2014, 114 mn.), persists in posing questions about how the past continues to shape the present, and how Sarajevo and its contemporary history still delineates the identity of Europe. 

Electron-acoustic solitons in an electron-beam plasma system with kappa-distributed electrons

Interaction of a stream of high-energy electrons with the background plasma plays an important role in the astrophysical phenomena such as interplanetary and stellar bow shock and Earth's foreshock emission. It is not yet fully understood how electrostatic solitary waves are produced at the bow shock. Interestingly, a population of energetic suprathermal electrons were also found to exist in those environments. Previously, we have studied the properties of negative electrostatic potential solitary structures exist in such a plasma with excess suprathermal electrons. In the present study, we investigate the existence conditions and propagation properties of electron-acoustic solitary waves in a plasma consisting of an electron beam fluid, a cold electron fluid, and hot suprathermal electrons modeled by a kappa-distribution function. The Sagdeev pseudopotential method was used to investigate the occurrence of stationary-profile solitary waves. We have determined how the electron-acoustic soliton characteristics depend on the electron beam parameters. It is found that the existence domain for solitons becomes narrower with an increase in the suprathermality of hot electrons, increasing the beam speed, decreasing the beam-to-cold electron population ratio. These results lead to a better understanding of the formation of electron-acoustic solitary waves observed in those space plasma systems characterized by kappa-distributed electrons and inertial drifting (beam) electrons.
