Testing and Final Construction of the Superconducting Magnet for the Alpha Magnetic Spectrometer
No full textThe Alpha Magnetic Spectrometer (AMS) is a particle physics experiment based on the International Space Station (ISS). At the heart of the detector is a large superconducting magnet, cooled to a temperature of 1.8 K by superfluid helium. The magnet and cryogenic system have been designed and built by Scientific Magnetics (formerly Space Cryomagnetics) of Culham, England. This paper describes the results from magnet testing, and the final assembly of the magnet and flight cryostat
Personal journey with Samuel Ting, Nobel Laureate physicist
No full textIn interviews with historians, descendants, and recent immigrants, this program begins with a description of the early 1880s when a wave of anti-Chinese sentiment swept across America, abetted by the Chinese Exclusion Act. Families were kept apart by both ancient custom and U.S. law. These immigrants were trapped between countries, at home neither in the U.S. nor in China. The law of the land, which separated these families, also provided relief as Chinese Americans turned to the courts for justice. Presents Chinese Americans contributions during World War II, and describes their struggles to prove their value both in war time and after returning home

Writing and the rights of reality: usurpation and potentiality in Derrida, Plato, Nietzsche, and Beckett
No full textThe thesis critically evaluates Jacques Derrida's conferral of the rights of reality on writing, focussing on his theory of an arche-text in light of the speculative nature of this theory. The theory is initially considered in the context of Derrida's elucidation of the usurpatory status of writing within the Platonic and Nietzschean texts. This consideration reveals an admission of writing's usurpatory status by both writers while at the same time demonstrating their awareness of the intrinsically speculative nature of this view, the significance of writing lying in its ability to exteriorise the radically indeterminate status of consciousness m relation to reality rather than its ability to displace consciousness or reality The analyses, therefore, not only bring the Derridean hypothesis of a repressive or phonocentric metaphysical episteme into question but also exhibit the historical and philosophical role of potentiality in relation to writing, writing's ultimate significance lying in its capacity to exteriorise our existence as a mode of potentiality. Accordingly, in the second half of the thesis the Derridean theory of writing is countered with a specifically Aristotelian theory of the text as it is exhibited in the prose of Samuel Beckett, an author whose significance lies in his close alignment with Derridean theory within contemporary criticism. It is demonstrated that this identification has obviated an awareness of the significance of potentiality within the Beckettian text, his work consequently being appraised in the previously neglected context of Aristotelian metaphysics

Leibniz, Pufendorf, and the possibility of moral self-governance
No full textIn his On the Duties of Man and Citizen, seventeenth century natural law theorist Samuel Pufendorf argues that the source of obligation lies in the command of a superior. This so-called voluntarist position was famously criticized by the rationalist Gottfried Leibniz. However, I wish to highlight several neglected aspects of the debate. Leibniz implicitly proposes a solution to a central moral problem: how one can be obligated voluntarily. His answer reflects a sort of motivational internalism, whereby the ideas of justice provide some motive cause of action, and virtue provides the rest. In this way, the agent acts voluntarily by making the principles of justice the principles of her action. Secondly, I show how this argument for the principles depends implicitly on his science of right, established in his earliest writings on jurisprudence. These principles are constituent of the nature of rational substance. It then becomes clear that Leibniz had long developed a foundation for self-governance, similar to Kantian autonomy, consisting in the agent's internal moral power to act (jus) and moral necessity to act (obligation). These points are exposed through a close reading of Leibniz's criticisms of Pufendorf on the end, object and efficient cause of natural law. © 2013 BSHP.[Anonymous], 1870, DIGESTA IUSTINIANI A; Aristotle, 1928, COLLECTED WORKS; Brown G, 2011, BRIT J HIST PHILOS, V19, P265, DOI 10.1080-09608788.2011.555162; Dutens Louis, 1768, LEIBNIZ OPERA OMNIA, P275; GROTIUS HUGO, 1625, DE JURE BELLI AC PAC; Grua Gaston, 1948, TEXTES INEDITS; Grua Gaston, 1956, LA JUSTICE HUMAIN SE; Hochstrasser T.
