Astronomy with a home computer
Here is a one-volume guide to just about everything computer-related for amateur astronomers!Today’s amateur astronomy is inextricably linked to personal computers. Computer-controlled "go-to" telescopes are inexpensive. CCD and webcam imaging make intensive use of the technology for capturing and processing images. Planetarium software provides information and an easy interface for telescopes. The Internet offers links to other astronomers, information, and software. The list goes on and on.
Astronomical sketching : A step-by-step introduction
At some time we have all gazed through the telescope eyepiece at the magnificent rings and banded globe of Saturn, or seen long shadows reaching across crater floors at the Moon’s terminator – and wondered at the sheer beauty of the sight. It seems almost anachronistic to think of sketching when CCD imaging is available, but astronomical sketching provides an entirely different and deeply personal experience. It means spending time at the eyepiece to really look at what you can see, training your eye to perceive ever greater detail to take the fullest advantage of your telescope's light grasp and resolution.
Astrobiology : Future perspectives
Astrobiology, a new exciting interdisciplinary research field, seeks to unravel the origin and evolution of life wherever it might exist in the Universe. The current view of the origin of life on Earth is that it is strongly connected to the origin and evolution of our planet and, indeed, of the Universe as a whole. We are fortunate to be living in an era where centuries of speculation about the two ancient and fundamental problems: the origin of life and its prevalence in the Universe are being replaced by experimental science. The subject of Astrobiology can be approached from many different perspectives. This book is focused on abiogenic organic matter from the viewpoint of astronomy and planetary science and considers its potential relevance to the origins of life on Earth and elsewhere. Guided by the review papers in this book, the concluding chapter aims to identify key questions to motivate future research and stimulate astrobiological applications of current and future research facilities and space missions. Today’s rich array of new spacecraft, telescopes and dedicated scientists promises a steady flow of discoveries and insights that will ultimately lead us to the answers we seek.
Arthropod Diversity and Conservation
Despite their enormous bulk and complexity of architecture, plants make up only around a quarter of a million of the 8 million or so species on Earth. The major components of biodiversity, instead, are the smaller, largely unseen, silent majority of invertebrates – most of which are arthropods. Vertebrates, a mere blip on the biotic horizon, are elevated in importance in the bigger scheme of things only by the human psyche. This collection of more than 30 peer-reviewed papers focuses on the diversity and conservation of arthropods, whose species inhabit virtually every recess and plane – and feature somewhere in virtually every food web – on the planet. Highlighting issues ranging from large-scale disturbance to local management, and from spatial heterogeneity to temporal patterns, these papers reflect some of the most exciting new research taking place today – and in some of the most biodiverse corners of the planet.
Advancing Quality of Life in a Turbulent World
Environmental issues continued to loom large in the last decade of the twentieth century,especially environmental problems related to rising levels of CO emissions and 2 other greenhouse gases on the planet’s average temperatures and, subsequently, storm patterns. Floods and droughts, in combination with unseasonably high and low temperatures became the norm rather than the exception for large expanses of Africa,Asia and Oceania. Even large areas of Europe and NorthAmerica were s- jected to recurrent floods and droughts and experienced unseasonable extremes of hot and cold temperatures associated with man-made intrusions into the natural environment. And, still, a global plan of action to haltman-related patterns of def- estation, desertification, and over-fishing of the seas has yet to come into being. At the same time, the number of regional conflicts and civil wars increased and, with them, the lives of many women, children, old people and other n- combatants were lost in these conflicts.
Advances in Meteoroid and Meteor Science
This volume is a compilation of articles that summarize the most recent results in meteor, meteoroid and related fields presented at the Meteoroids 2007 conference held at the impressive CosmoCaixa Science Museum in Barcelona, Spain. The conference took place between the 11th and the 15th of June and was organized by the Institute of Space Sciences (Consejo Superior de Investigaciones Científicas, CSIC) and the Institut d'Estudis Espacials de Catalunya (IEEC). Researchers in meteor science and supporting fields representing more than 20 countries participated at this international conference.
Academic Flying and the Means of Communication
This book shines a light on how and why academic work became entwined with air travel, and what can be done to change academia’s flying habit. The starting point of the book is that flying is only one means of scholarly communication among many, and that the state of the planet now obliges us to shift to other means.
A Short Course in Geology for Civil Engineers
Explains the process of ground formation - what it is made of and how it behaves as an engineering material. This enables the civil engineer to work from a few first principles to determine if the ground is an asset or a hazard. It focuses on the tectonic plate mechanisms that give rise to the geology of our planet and describes the way these create hazards such as volcanic eruptions, earthquakes and tsunamis. The authors state that groundwater can be both a resource and a hazard and through this book they provide an overview of the origins of geomaterials.
A History of Physical Theories of Comets, From Aristotle to Whipple
The book describes the major physical theories of comets in the past two millennia. It demonstrates the evolution of ideas about the nature, position, motion and physical constitution of comets from Aristotle to Whipple. Unlike the available works on the history of comets, which either illustrate relatively short periods in the history of physical cometology or portray a landscape view without adequate details, the present study focuses on details of each theory. It also investigates the interaction between observational and mathematical astronomy, and the physical sciences in defining the properties of comets.
A Comparison of the Dynamical Evolution of Planetary Systems ; Proceedings of the Sixth Alexander von Humboldt Colloquium on Celestial Mechanics Bad Hofgastein (Austria), 21-27 March 2004
The papers in this volume cover a wide range of subjects covering the most recent developments in Celestial Mechanics from the theoretical point of nonlinear dynamical systems to the application to real problems. We emphasize the papers on the formation of planetary systems, their stability and also the problem of habitable zones in extrasolar planetary systems. A special topic is the stability of Trojans in our planetary system, where more and more realistic dynamical models are used to explain their complex motions: besides the important contribution from the theoretical point of view, the results of several numerical experiments unraveled the structure of the stable zone around the librations points. This volume will be of interest to astronomers and mathematicians interested in Hamiltonian mechanics and in the dynamics of planetary systems.
A companion to astronomy and astrophysics : Chronology and glossary with data tables
Astronomy and Astrophysics is a comprehensive, fundamental, up-to-date reference book. It is filled with vital information and basic facts for amateur astronomers and professional astrophysicists, and for anyone interested in the Universe, from the Earth and other planets to the stars, galaxies and beyond. Although serious and thorough, the language, and ideas will attract the general reader, as well as students and professionals. Astronomy and Astrophysics consists of two main parts, a Timeline and a Dictionary. The Timeline is a concise history, arranged chronologically, which provides the complete story of cosmic discovery from early Chinese and Greek astronomy to the latest findings of modern astrophysics and robotic spacecraft.
(IOT) Based street light, energy saving control system
Energy efficiency simply means using less energy to perform the same task. That is, to eliminate energy waste. Reducing energy use limits the number of carbon emissions in the environment, in turn, conserving energy produces a higher quality of life, helping create a healthier planet, or at least helping sustain the resources we already have; and if not now, then when? Hence, the main purpose of our project was to design and implement an energy saving street lights’ system, remotely controlling the lights so they consume the least amounts of energy possible using the modern technology; internet of things.
