Impact of Mixture Chamber Gas on Direct-Drive Inertial Fusion Energy Targets

submitted by: RobertMartin
Robert Martin's PhD Defense from the University of California San Diego Department of Mechanical and Aerospace Engineering. Dr. Martin developed a multi-component computational fluid dynamics algorithm to study the evolution of chamber gas between subsequent inertial fusion energy burns in a proposed powerplant design. He used these results to study the impact of chamber gas on direct-drive target survival and proposed a safe operating regime as well as a cold gas jet co-injection scheme to...

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 ( ) and the department of engineering of the University of Chile ( ), and after some deliberation those that have see it agree that it works, it’s simple and obvious. See at (click...
