Proposal for a New High Precision Particle Detector
THE precision commonly quoted when measuring the position of a charged particle track is ±0.3 mm for wire plane spark chambers1, ±0.4 mm for streamer chambers2 and ±0.7 mm for multiwire proportional chambers3,4. With the onset of the new generation of synchrotrons there is a need for detectors with better resolution. This arises from the fact that the accelerated particles will receive only small deflexions in analysing magnets. This article consists of a proposal for a detector that will provide the necessary increase in resolution.
A wide-gap streamer chamber
Abstract A 20-cm gap streamer chamber is described together with details of the high voltage circuitry. An analysis of measurements on the tracks in the various modes of operation shows that an angular resolution of 1.5 mrad is attainable.
Nietzsche's Task: An Interpretation of Beyond Good and Evil
When Nictzsche published Beyond Good and Evil in 1886, he told a friend that it was a book that would not be read properly until "around the year 2000". Now Laurence Lampert sets out to fulfill this prophecy by providing a section by section interpretation of this philosophical masterpiece that emphasises its unity and depth as a comprehensive new doctrine on nature and humanity. According to Lampert, Nietzsche begins with a critique of philosophy that is ultimately affirmative, because it shows how philosophy can arrive at a defensible ontological account of the way of all beings. Nietzsche next argues that a new post-Christian religion can arise out of the affirmation of the world disclosed to philosophy. Then, turning to the implications of the new ontology for morality and politics, Nietzsche argues that these can be reconstituted on the fundamental insights of the new philosophy. Nietzsche's comprehensive depiction of this anti-Platonic philosophy ends with a chapter on nobility, in which he contends that what can now be publicly celebrated as noble in our species are its highest achievements of mind and spirit.
