Modeling Early Galaxies Using Radiation Hydrodynamics

submitted by: btolo
This simulation uses a flux-limited diffusion solver to explore the radiation hydrodynamics of early galaxies, in particular, the ionizing radiation created by Population III stars. At the time of this rendering, the simulation has evolved to a redshift of 3.5. The simulation volume is 11.2 comoving megaparsecs, and has a uniform grid of 1024^3 cells, with over 1 billion dark matter and star particles. The simulation was computed on resources of the National Institute for Computational...

Interstellar Space Travel using Phase-shifted Electrodynamic Propulsion

submitted by: MFerreiraJr

It is a brief explanation about phase-shifted electrodynamic force (f ≥ c/L) causing electrodynamic drag, and consequently, generating propulsion in the outer space, and perhaps enabling fast interstellar travel.

Sex Differences in Math-Intensive Fields

submitted by: stevececi
Despite impressive employment gains in many fields of science, women remain underrepresented in fields requiring intensive use of mathematics. Here we discuss three potential explanations for women’s underrepresentation: (a) male–female mathematical and spatial ability gaps, (b) sex discrimination, and (c) sex differences in career preferences and lifestyle choices. Synthesizing findings from psychology, endocrinology, sociology, economics, and education leads to the conclusion that,...

Effect of Momentum Dismemberment on Linear Momentum

submitted by: wjeconsultant
Propulsion system using fluids that permits strong generation of thrust for extended periods of time in micro-gravity. The idea has been presented to academics at the department of science of the University of Chile ( http://www.ciencias.uchile.cl/ciencias/ ) and the department of engineering of the University of Chile ( http://escuela.ing.uchile.cl/ ), and after some deliberation those that have see it agree that it works, it’s simple and obvious. See at http://www.wjetech.cl/ (click...
