In the X-ray band, they offer the potential of probing accretion physics down to the event horizon. Recent work has used frequency-and energy-dependent time lags as tools for studying relativistic reverberation around the black holes in several Seyfert galaxies. This was achieved due to the ...
This paper presents an analysis of the different types of reasoning and physical explanation used in science, common thought, and physics teaching. It then reflects on the learning difficulties connected with these various approaches, and suggests some possible didactic strategies. Although causal reasoni...
clock, mechanical or electrical device other than a watch for displaying time. A clock is a machine in which a device that performs regular movements in equal intervals of time is linked to a counting mechanism that records the number of movements. All clocks, of whatever form—whether 12-hou...
A brief but clear and complete account is given for two analytical methods of calculating correlation functions in quantum statistical physics from first principles鈥攖he widely used method of two-time temperature Green's functions (the GF method) and a new, "direct algebraic" (DA) method. The...
A method of computing the time dependence of strength of brittle solids in surface-active media which do not change the principal mechanism of fracture but only accelerate crack growth is presented. The method is based on applying the Fick law to the surface diffusion of the medium on the free...
A diffusion model of the time evolution of loss rates caused by a step in collimator position is presented. It builds upon the model of Seidel (1994) and i... G Stancari - 《Physics》 被引量: 11发表: 2011年 High intensity circular proton accelerators Circular machines suitable for the ac...
oscillator that the frequency is adjusted while preparing a measurement facility and measuring the frequency by the measurement facility since periodic re-measurement is required and zero adjustment is needed when a crystal oscillation element is deteriorated with time change and the frequency is changed...
