, 2019 In the modern era, the notion of space travel is generally one of greater acceptance and ease than in times previously. Moreover, a greater number of nations (and now even private entities) have the technological capabilities to launch manned and ...

Revista Mexicana de Fisica, 49, 191 (2003), 2012 Elementary concepts from general physics and thermodynamics have been used to analyze rocket propulsion. Making some reasonable assumptions, an expression for the exit velocity of the gases is found. From that expression one can conclude what are the desired properties for a rocket fuel.

A survey of selected coastal vegetation communities of Florida [PDF]
, 1977 A survey of coastal vegetation around Florida was conducted during 1973 and 1974. Seventeen sites were selected and sampled using the transect method to determine species occurrence, relative densities, and habitat development and structure.

The Ultimate Limits of the Relativistic Rocket Equation. The Planck Photon Rocket [PDF]
Acta Astronautica, Vol. 136, July 2017, Pages 144-147, 2018 In this paper we look at the ultimate limits of a photon propulsion rocket. The maximum velocity for a photon propulsion rocket is just below the speed of light and is a function of the reduced Compton wavelength of the heaviest subatomic particles in the rocket. We are basically combining the relativistic rocket equation with Haug's new insight on the
