For many years, historians of the Re naissance have lauded the value of forg eries and fakes. Counterfeit documents, passed off as real, offer invaluable clues about the wider culture in which they were made. They iHuminate subtle, taken-for-granted assumptions and habits of the time; after all, forgers must have had particular ideas in mind about what

The Physics of Carbon Dust Around WC Stars [PDF]
Symposium - International Astronomical Union, 1995 The physical properties of dust in WR shells are investigated in detail. It has been found that carbon grains may grow in the severe conditions of WR shells due to collisions with impinging positive carbon ions. Detailed physical models of carbon dust and dust production rates for selected WC stars have been calculated.

Physical Processes on Interplanetary Dust
2001This chapter discusses physical processes affecting interplanetary dust grains, including processes determining dust formation, growth, disruption, and alteration. Computer simulations and laboratory studies of coagulation and aggregation show that mutual collisions between solid grains determine the growth of solid aggregates in the early solar system

Margaret Cavendish and the Physics of Dust
Abstract Philip Pullman’s trilogies His Dark Materials and The Book of Dust center around the quest to understand the enigmatic substance known as Dust. Through the idea of Dust, Pullman explores contemporary ideas of theoretical physics (dark matter, quantum mechanics, string theory) in ways that connect to seventeenth-century theories ...Kristen Poole

Physics and Chemistry of Circumstellar Dust Shells
2013Circumstellar dust, the astronomical dust that forms around a star, provides today's researchers with important clues for understanding how the Universe has evolved. This volume examines the structure, dynamics and observable consequences of the dust clouds surrounding highly evolved stars on the Giant Branch.

Dust in tokamaks: An overview of the physical model of the dust in tokamaks code
Physics of Plasmas, 2010The dynamical behavior of dust produced in tokamaks is an important issue for fusion. In this work, the current status of the dust in tokamaks (DTOKS) [J. D. Martin et al., Europhys Lett. 83, 65001 (2008)] dust transport code will be presented. A detailed description of the various elements of its underlying physical model will be given together with ...

Dust in jupiter's magnetosphere: Physical processes
Planetary and Space Science, 1980Abstract The physical processes acting on charged microscopic dust grains in the Jovian magnetosphere are examined. Such small dust grains are believed to be injected continuously into the magnetosphere via volcanic activity on Io. It is shown that electromagnetic forces dominate the dust particle dynamics, and that these particles behave ...

Physics and Astrophysics of Interstellar Dust
1978Although this exposition covers the topics discussed in the series of lectures presented at the Summer School on Infrared Astronomy, their order has been changed. This is largely a result of the experience gained during the course. A number of results not presented in Erice have been included for completeness because there was inadequate time to do so ...

Physical properties of cometary and interplanetary dust
Planetary and Space Science, 2007Abstract In the absence of numerous in situ studies, physical properties of cosmic dust may be derived from observations of their light scattering and thermal properties, through numerical simulations making use of realistic assumptions. Estimations about cometary and interplanetary dust composition, structure, size, as well as about their light ...
