Computations in fusion Physics

Applied Mathematics and Computation, 1986
The modern approach to nuclear fusion uses inertial confinement by a high-power laser beam, and the computer codes used to simulate the plasma behaviour now contain a lot of physics. Nonlinear interaction of a laser with a turbulent plasma is a major topic of experimental and numerical study. Simulation can be on either the particle or the hydrodynamic

Simulating physics with computers

International Journal of Theoretical Physics, 1982
This chapter describes the possibility of simulating physics in the classical approximation, a thing which is usually described by local differential equations. But the physical world is quantum mechanical, and therefore the proper problem is the simulation of quantum physics. A computer which will give the same probabilities as the quantum system does.

Physical limitations of a computer

ACM SIGARCH Computer Architecture News, 1993
This article introduces the physical limitations of a computer and describes limiting architectural impact of the laws of physics on computer hardware design and shows how imaginative application of skills of a computer architect and artistic management of the circuitry may override some of these limitations.

Computational mineral physics and the physical properties of perovskite

Philosophical Transactions of the Royal Society of London. Series A: Mathematical, Physical and Engineering Sciences, 2002
The inherent uncertainties in modern first-principles calculations are reviewed using geophysically relevant examples. The elastic constants of perovskite at lower-mantle temperatures and pressures are calculated using ab initio molecular dynamics. These are used in conjunction with seismic tomographic models to estimate that the lateral temperature ...

Computability in Analysis and Physics

1989
Since their inception, the Perspectives in Logic and Lecture Notes in Logic series have published seminal works by leading logicians. Many of the original books in the series have been unavailable for years, but they are now in print once again. In this volume, the first publication in the Perspectives in Logic series, Pour-El and Richards present the ...

The physics of computed radiography

Physics in Medicine and Biology, 2002
Cassette-based computed radiography (CR) systems have continued to evolve in parallel with integrated, instant readout digital radiography (DR) systems. The image quality of present day CR systems is approaching its theoretical limits but is significantly inferior to DR. Further improvements in CR image quality require improved concepts.

Computation and Fundamental Physics

The Computer Journal, 2012
‘What is computation?” is not mere taxonomy, nor simply an aid in our anthropocentric obsession with explaining our thinking process. Instead it is relevant to some of the deepest questions in the nature of the physics of our universe. Understanding what computation is may be more essential to us than we might have imagined.

A computing architecture for physics

Proceedings of the 2nd conference on Computing frontiers, 2005
In this paper, we show how a computing architecture, called "Salt", might be able to implement the workings of a particular Discrete Space-Time-State model of Physics (DSTSP). While what is presented is certainly not a correct model of fundamental processes in physics, it illustrates how such models could give us insights into new methods of modeling ...

Physical computing for everyone

2017 IEEE/ACM 39th International Conference on Software Engineering: Software Engineering Education and Training Track (ICSE-SEET), 2017
Thanks to Moore's Law, embeddable microcontroller-based devices continue to get cheaper, faster, and include more integrated sensors and networking options. In 2016, the BBC and a host of technical partners, including Microsoft, delivered such a physical computing device, the micro:bit, to every 5th grader in the UK.
