Composition is not research

Copyright © Cambridge University Press 2015Composers in academic institutions are increasingly required to describe their activities in terms of 'research ' - formulating 'research questions', 'research narratives', 'aims' and 'outcomes'. Research plans and funding applications require one to specify the nature of the original contribution that will be made by a piece of music, even before it is composed. These requirements lead to an emphasis on collaborative work, technology and superficial novelty of format. Yet the very idea that musical composition is a form of research is a category error: music is a domain of thought whose cognitive dimension lies in embodiment, revelation or presentation, but not in investigation and description. It is argued here that the idea of composition as research is not only objectively false but inimical to genuine musical originality

Laser-heated rocket studies

CW laser heated rocket propulsion was investigated in both the flowing core and stationary core configurations. The laser radiation considered was 10.6 micrometers, and the working gas was unseeded hydrogen. The areas investigated included initiation of a hydrogen plasma capable of absorbing laser radiation, the radiation emission properties of hot, ionized hydrogen, the flow of hot hydrogen while absorbing and radiating, the heat losses from the gas and the rocket performance. The stationary core configuration was investigated qualitatively and semi-quantitatively. It was found that the flowing core rockets can have specific impulses between 1,500 and 3,300 sec. They are small devices, whose heating zone is only a millimeter to a few centimeters long, and millimeters to centimeters in radius, for laser power levels varying from 10 to 5,000 kW, and pressure levels of 3 to 10 atm. Heat protection of the walls is a vital necessity, though the fraction of laser power lost to the walls can be as low as 10% for larger powers, making the rockets thermally efficient
