The effect of atmospheric pressure on Snowball Earth deglaciation
No full textThe most common explanation for the escape from a Snowball Earth state involves, among other factors, a strong greenhouse effect caused by a large partial pressure of CO2. This leads to an increase in surface pressure, which most models do not account for. With a higher surface pressure, pressure broadening increases, and convection reaches a deeper layer, both of which result in higher surface temperatures. The latter mechanism, which has not previously been reported, is found to be a greater source of warming than pressure broadening in the normal range of CO2 partial pressures at the point of deglaciation
Sovereign-less subject and the possibility of resistance
No full textThis article explores exclusionary practices of contemporary politics and alternative forms of resistance. It starts off explaining how Giorgio Agamben's theory can be understood in the context of resistance. In so doing, it turns to the arguments put forward by Edkins and Pin-Fat. In their article 'Through the Wire', they identify two forms of resistance. Drawing on Agamben's thought: refusal and the assumption of bare life. This article argues that these two forms are not sufficient for thinking resistance. This is so because of a gap in Agamben's thought and the way Edkins and Pin-Fat read him. In order to explore resistance in a more fruitful way, the article critiques Edkins and Pin-Fat's conclusions on the understanding bare life as a form of resistance; it amends Agamben's account by explaining the move from bare life to whatever being, and ultimately, the article finds whatever being as a fruitful way of understanding resistance on the example of Tiananmen. At the end I conclude that the Tiananmen protest successfully challenged the sovereign power from the position of in-between. © The Author(s), 2009
Art. XVII.—The Yi king of the Chinese, as a book of Divination and Philosophy
No full textAn important point in the study of the Yi king is the recognition of its existence before Wen wang's time. The elements of main difference between the Yi king of the early dynasties and that of Wen wang was in the order of the Kwa. The same names were current, and probably the admonitory remarks were, many of them, the same also. These remarks are all anonymous, and we are at liberty to guess who wrote them. The appendices are anonymous also, and they may have mainly been written by men before the time of Confucius. The three sages, Wen wang, Cheu kung, and Confucius, were all editors, and Fu hi the original author.</jats:p
Crisis is governance : sub-prime, the traumatic event, and bare life
No full textThe article provides a critical analysis of the role of discourses of trauma and the traumatic event in constituting the ethico-political possibilities and limits of the subprime crisis. It charts the invocation of metaphors of a financial Tsunami and pervasive media focus on
emotional ‘responses’ like fear, anger, and blame, suggesting that such traumatic discourses
constituted the subprime crisis as a singular and catastrophic ‘event’ demanding of particular
(humanitarian) responses. We draw upon the thought of Giorgio Agamben to render this constituted logic of event and response in terms of the concomitant production of bare life; the savers and homeowners who became ‘helpless victims’ in need of rescue. We therefore
tie the ongoing production of the sovereign power of global finance to broader processes that
entail the enfolding and securing of everyday financial subjects. These arguments are illustrated via an analysis of three subjects: the economy, bankers and borrowers. We argue that it was the movement between subject positions – from safe to vulnerable, from
entrepreneurial to greedy, from victim to survivor, etc. - that marked out the effective manner
of governance, confirming in this process sovereign categories of financial citizenship, asset
based welfare, and securitisation that many would posit as the very problem. In short, (the
way that the) crisis (was constituted) is governance
Molecular structural dynamics in water–ethanol mixtures: Spectroscopy with polarized neutrons simultaneously accessing collective and self-diffusion
No full textP6_8 B-29 Boomer Bomber
No full textIn this paper, the feasibility of floating a B-29 bomber crashed at the bottom of Lake Mead with flotation bags (as is done in the game Fallout New Vegas) is discussed, where it is found possible as the buoyant forces overcome the weight. However the mass of nitrogen required to inflate the bags fully is found to be far too high to be realistically carried by one man to the location and sunk to such a depth
P6_5 Simulating Charged Particle Motion in Electromagnetic Fields using Numerical Methods
No full textWe investigated the motion of a charged particle within an electromagnetic field using both the Euler and Boris methods. It has been shown that if the electric and magnetic field are perpendicular to one another then a charged particle will follow a cycloidal motion. We have also shown that the Euler method breaks down in the presence of a magnetic field and conclude that the Boris method is superior for simulating charge particle motion in fields
P6_2 Mike Drop: Calculating the stretch of rope
No full textYoung’s Modulus is used to calculate the stretch of a material based on the force exerted and theinitial length. In this paper, this principal value will be used to calculate the predicted stretchof a sampled dynamic climbing rope due to falls of sequential heights and compare them to theadvertised stretch specification
P6_7 Doom Divers
No full textIn this paper the feasibility of a catapult launching a goblin in a crude wing-suit used to guide itself to its target is discussed. The forces experienced by the goblin at launch are calculated to be roughly 336g for 0.055s, enough to severely injure them. The maximum range of such a catapult, with the wing's effect taken into account, would be 3km. It is found that the goblin would not serve any purpose beyond a dumb projectile, rendering the main purpose of the catapult obsolete
