A Synoptic History of Classical Rhetoric $57.95 The purpose of history is to help people understand the present by providing a sense of continuity to their lives. The history of western civilization begins in Ancient Greece. So much of what we observe around us — art, architecture, poetry, drama, and political systems — is derived from the Greeks. Even religious beliefs and beliefs about the solar system emanate from the writings of Greek and Roman philosophers. Writing itself is a phenomenon of Greek civilization. Students seeking to understand the social impact of technologies such as writing, print, and television, must begin their study with figures such as Socrates, who was one of the first to be concerned with the changes in social interaction and consciousness wrought by the emergence of writing on portable material. For students of language, an awareness of the classical world is particularly important. The study of human discourse is an entirely western phenomenon. As far as one can judge from surviving evidence, the Greeks were the only people of the ancient world who endeavored to analyze the ways in which human beings communicate with each other. Greece is, therefore, the birthplace of the art of discourse, which includes not only rhetoric, but also logic and grammar. Although many other ancient civilizations produced literature, only the Greeks produced analytic, expository treatises that attempted to discover the actual bases of human communication. Written treatises and school “systems” which allowed rhetorical discoveries to be transmitted to others enabled the Greeks and later the Romans to amass a considerable body of precepts to guide speakers and writers. This body of precepts forms the basis for the study of “rhetoric” — the art of human discourse. This book provides a clear understanding of the classical roots of rhetoric. While no single volume can account for every idea developed by the ancients on the art of rhetoric, this book seeks to present the concepts that will most |

A comparative analysis of control techniques for formation flying spacecraft in an Earth/Moon-Sun L(2)-centered lissajous orbit . $49.99 In this thesis, several control techniques are applied to an occulter satellite for a given formation flying mission. This research is in collaboration with the Flight Dynamics Analysis branch at the NASA Goddard Space Flight Center in Greenbelt, Maryland. The spacecraft is part of a leader-follower configuration which orbits about the Earth/Moon-Sun L2 libration point in a lissajous orbit. A controller is required to maintain a distance of 50,000 km between the occulter and the leader satellite in the radial direction with respect to the orbit. The occulter is allowed a tolerance range of 10 m within the “shadow” of the leader. In addition, the controller must also minimize the fuel usage (Deltav) needed to maintain the occulter’s trajectory.;The spacecraft model follows the equations of motion defined by the circular restricted three body problem (CR3BP), where the primary bodies are defined to be the Earth/Moon system and the Sun. The dynamic model also incorporates thruster errors and misalignments, orbital sensor noise, environmental perturbations and disturbances, and additional modeling errors/uncertainties.;The control techniques analyzed in this paper consist of several linear (PID, Linear Quadratic Regulator, and Hinfinity) and one nonlinear controller (Sliding Mode Control). All control techniques are compared based on the overall minimization of trajectory error and fuel usage, ease of implementation, and robustness against disturbances and perturbations such as solar radiation pressure and thruster misalignments.;The results of this research show that of the control techniques analyzed, the Linear Quadratic Regulator (LQR) and Sliding Mode Control (SMC) satisfy the mission requirements. While LQR uses less fuel to satisfy given mission requirements, the SMC would also be a suitable choice of control if a mission weighted accuracy over fuel usage. |

Accretion of Extraterrestrial Matter Throughout Earth’s History $138.73 Every year Earth is bombarded with about 40,000 tons of extraterrestrial material. This includes microscopic cosmic dust particles shed by comets and asteroids in outer space, meteorites, as well as large comets and asteroids that have led to catastrophic events in the geologic past. Originally considered only a curiosity, extraterrestrial matter found on Earth provides the only samples we have from comets, asteroids and other planets. Only recently mankind has started to actively collect extraterrestrial matter in space (Apollo program, Stardust mission) rather than to wait for its delivery to Earth. Still, most of our knowledge of the origin and evolution of our solar system is based on careful studies of meteorites, cosmic dust, and traces of large impact events in the geologic record such as the mass extinction that terminated the Cretaceous Period and led to the extinction of the dinosaurs. This book summarizes our current knowledge of the properties, origin, orbital evolution and accretion mechanism of extraterrestrial matter accreted on Earth and sheds light on accretion processes and fluxes in the geologic past. The chapters in the first part of the book are arranged in order to follow extraterrestrial matter from its origin in space, its orbital evolution on its way to Earth, its interaction with the Earth magnetosphere and atmosphere to its more or less violent collision with the Earth’s surface. In the second part of the book several chapters deal with the present?day flux of cosmic dust and meteorites to Earth. Finally, several chapters deal with the reconstruction of the accretion history of extraterrestrial matter on Earth, starting with the most recent geologic past and ending with the very early, violent accretion period shortly after the formation of Earth, Moon and other solid planets in our solar system. |

Alien Covenant: Genesis I $15.59 Alien Covenant: Genesis I explores the idea of ancient astronauts – humanoid aliens who came to Earth a long time ago and created safe havens and mankind. It presents a different story of creation, with an imaginative account of how the solar system came to be. As astronauts on a mission, God, Satan and the angels come alive in this revealing adaptation of the banned story of Adam and Eve, where lords and ladies require mono-atomic gold powder for everlasting life.A foreign legion of dragon-dog angels from the Planet of Fates, farming in the Garden of Eden and mining nearby, strike against God, who replaces them with hew-brutes and a hew-man called Adam. But Adam and his helper, Eve, mate against God’s law and are expelled into the wilderness. Is this part of God’s plan to lead his mission in a new direction? What are the Ancient Mysteries all about? Some may label this book as heresy, even blasphemy, but others who reason will smile at the cleverly suggested origins of names, stories, objects and customs from around the world.While in eighth grade at Catholic school, James Hansen questioned supernaturalism, especially miracles in The Holy Bible. He asked his teacher, “How come the miracles that happened thousands of years ago do not happen today?” Her answer – “It is a mystery.” – has been stuck in his mind ever since. James has researched mythology, religion, science and ancient astronauts for more than 40 years.He graduated from Oregon State University and attended graduate school at Harvard. Hansen lived in England for 10 years and has visited 22 countries, working for 24 years as a civil engineering assistant in the U.S. Air Force, retiring as a master sergeant. A recent lymphoma survivor, he lives in Oregon with his wife. Alien Covenant: Genesis I is his first book. |

Animatronica [Captain Spycer #3] $4.99 “Funny!” says Hugo winner Larry Niven about science fiction of J. D. Crayne. In the third adventure of Captain Spycer and her zany band of space heroes, the Earth is doomed! Or maybe it’s Callisto that’s doomed. On the other hand, perhaps it’s just Anaheim, California. The only chance Earth has to avoid possible annihilation is to send the Command Force’s intrepid Captain Sherilyn Spycer to the rescue! The Captain and her crew of stalwart civilization-savers are on their way, and the hero business may never be the same. A rogue pleasure satellite, missing for over two hundred years, is about to crash through the solar system, causing wide-spread destruction, the downfall of civilization, and the violation of beautiful young women. That’s what one eminent scientist claims, but he and his team of research geniuses are missing in action. They took off for the satellite two weeks ago, and haven’t been heard from since. The date of destruction draws ever closer and doom is staring humanity square in the face. Follow the incredible adventures of Captain Spycer and her crew as they brave the evil android Queen Animatronica, who is dedicated to the obliteration of all living things. Cheer them on as they face 150 meter roller-coasters and broken teeth from antique chocolate bars. It’s danger, excitement, and nerve-tingling adventure, plus a lot of familiar faces that you know and love. The crew of the good ship RayRunner is on the job! The disembodied head of Professor Andre Groppe is here to imagine the unimaginable, while his scaly red aide, Col. Krabchake, is primarily interested in the satellite’s savory green tree frogs. Rugged duraluminum robot Peter Decade has all of the answers, butonly if someone asks the right questions. Dr. Brian Lefarge, the perpetually confused innocent, is certain that everybody means well and does the best he can with someone else’s plastic arm. Space adventure at its very best; accept no substitutes! |

Atmosphere Of Jupiter $47.46 The atmosphere of Jupiter is the largest planetary atmosphere in the Solar System. It is primarily made of molecular hydrogen and helium in roughly solar proportions; other chemical compounds are present only in small amounts and include: methane, ammonia, hydrogen sulfide and water. Although water is thought to reside deep in the atmosphere, its directly measured concentration is very low. The oxygen, nitrogen, sulfur, and noble gas abundances in Jupiter’s atmosphere exceed solar values by a factor of about three. The atmosphere of Jupiter lacks a clear lower boundary and gradually transitions into the fluid interior of the planet. From lowest to highest, the atmospheric layers are the troposphere, stratosphere, thermosphere and exosphere. Each layer has characteristic temperature gradients. The lowest layer, the troposphere, has a complicated system of clouds and hazes, comprising layers of ammonia, ammonium hydrosulfide and water. The upper ammonia clouds visible at Jupiter’s surface are organized in a dozen zonal bands parallel to the equator and are bounded by powerful zonal atmospheric flows (winds) known as jets. |
