The Earth as a Distant Planet by M. Vázquez,E. Pallé,P. Montañés Rodríguez Pdf

In The Earth as a Distant Planet, the authors become external observers of our solar system from a distance and try to determine how one can understand how Earth, the third in distance to the central star, is essentially unique and capable of sustaining life. The knowledge gained from this original perspective is then applied to the search for other planets outside the solar system, or exoplanets. Since the discovery in 1992 of the first exoplanet, the number of planet detections has increased exponentially and ambitious missions are already being planned for the future. The exploration of Earth and the rest of the rocky planets are Rosetta stones in classifying and understanding the multiplicity of planetary systems that exist in our galaxy. In time, statistics on the formation and evolution of exoplanets will be available and will provide vital information for solving some of the unanswered questions about the formation, as well as evolution of our own world and solar system. Special attention is paid to the biosignatures (signs of life) detectable in the Earth's reflected spectra and the search for life in the universe. The authors are experts on the subject of extrasolar planets. They provide an introductory but also very much up-to-date text, making this book suitable for researchers and for advanced students in astronomy and astrophysics.

Distant Planet by Colin Shiels Pdf

The Mayans knew of its great destructive power, the Angry One they had called it.'JAMES HOLLINS has been wrong before and it cost him his reputation. In fact, it is why he now holds the job that nobody wants; isolated, pushed aside and forgotten about: an astronomer at the Armstrong Observatory on the Moon. As he carries out his duties, he soon discovers that the rogue planemo, Ronin, a drifter through space, is heading towards our solar system. But, with his credibility in tatters and the ridicule still felt after his false data detected an asteroid heading for Earth ten years ago, who can he make listen?Hollins manages to transfer all of the information to a childhood friend, one of the president's aides, but when she is involved in a car accident before she can deliver the message, it becomes clear that someone on Earth is already aware of the situation and they would rather nobody else found out. This is confirmed when the comms system is destroyed and all contact between the Moon and Earth is severed. With no way of warning Earth of its fate, all attention is turned to The Ark Project.

Modern Physics with Modern Computational Methods by John Morrison Pdf

Modern Physics with Modern Computational Methods, Third Edition presents the ideas that have shaped modern physics and provides an introduction to current research in the different fields of physics. Intended as the text for a first course in modern physics following an introductory course in physics with calculus, the book begins with a brief and focused account of experiments that led to the formulation of the new quantum theory, while ensuing chapters go more deeply into the underlying physics. In this new edition, the differential equations that arise are converted into sets of linear equation or matrix equations by making a finite difference approximation of the derivatives or by using the spline collocation method. MATLAB programs are described for solving the eigenvalue equations for a particle in a finite well and the simple harmonic oscillator and for solving the radial equation for hydrogen. The lowest-lying solutions of these problems are plotted using MATLAB and the physical significance of these solutions are discussed. Each of the later chapters conclude with a description of modern developments. Makes critical topics accessible by illustrating them with simple examples and figures Presents modern quantum mechanical concepts systematically and applies them consistently throughout the book Utilizes modern computational methods with MATLAB programs to solve the equations that arise in physics, and describes the programs and solutions in detail Covers foundational topics, including transition probabilities, crystal structure, reciprocal lattices, and Bloch theorem to build understanding of applications, such as lasers and semiconductor devices Features expanded exercises and problems at the end of each chapter as well as multiple appendices for quick reference

DARK MATTER AND DARK ENERGY, BLACK HOLES, … by John Dark-Physics Pdf

Through a short story I will provide answers to some questions that many of us are asking about our Universe. And in particular, I will explain where would be the missing mass of the Universe (the Dark Matter) and what would be the Dark Energy and the Dark Matter. I will also discuss what happens inside a black-hole when a planet is sucked in: I have broken down the global movement into two separate movements... I have analyzed the consequences of my analysis on black-holes for our Universe and the conclusions are very interesting! My analysis allowed me to address the following points: the Energy Density of the Vacuum of the space, the Cosmological Constant, the Hubble Constant, the expansion of our Universe and the acceleration of this expansion, the compatibility links between my Theory and the current physics, … I have also shown the extraordinary power of the Gravity! And I have also shown that far-away travels into the space would be possible, in agreement with my Theory, by reducing the number of obstacles! Finally, I have mentioned the new questions that arise when some answers are found... and in particular what technology to make a spacecraft that could go at a speed close to the speed of light?

The Search for Earth's Twin by Stuart G. Clark Pdf

In 1995 two Swiss astronomers discovered a planet circling a star other than our Sun. This changed our perception of the Universe forever, proving that Earth and the other celestial bodies in our Solar System are not alone in outer space. Now, after two decades of exploration, more than 860 planets have been discovered, many of which are completely unlike anything else we know. Some are blacker than coal; some are bathed in molten lava; others are perpetually scoured by hurricane-force winds; some have not one sun but two that rise in the morning, and others are perpetually drowned in global oceans. But as well as strange, uninhabitable lands, there is familiarity too. Some of these alien worlds are strikingly similar to planets in our Solar System. Astronomers now know of planets just like Jupiter, Neptune, Mars and Mercury orbiting stars similar to our Sun, both nearby and deep into space. Authoritatively written and fully up to date on this fast-moving area of science, The Search for the Earth's Twin will take you on a journey through the cosmos via frozen wastelands, slow-moving globes and fiery volcanic bodies, to planets that can - and just might - sustain complex life. The prospect of discovering the Earth's twin is now tantalisingly close.

Astronomy Through the Ages by Sir Robert Wilson Pdf

From an historical perspective, this text presents an entirely non- mathematical introduction to astronomy from the first endeavours of the ancients to the current developments in research enabled by cutting edge technological advances. Free of mathematics and complex graphs, the book nevertheless explains deep concepts of space and time, of relativity and quantum mechanics, and of origin and nature of the universe. It conveys not only the intrinsic fascination of the subject, but also the human side and the scientific method as practised by Kepler, defined and elucidated by Galileo, and then demonstrated by Newton.

The Stuff of Science Fiction by Gary Westfahl Pdf

While students and general readers typically cannot relate to esoteric definitions of science fiction, they readily understand the genre as a literature that characteristically deals with subjects such as new inventions, space, robot and aliens. This book looks at science fiction in precisely this manner, with twenty-one chapters that each deal with a subject that is repeatedly addressed in science fiction of recent centuries. Based on a packet of original essays that the author assembled for his classes, the book could serve as a supplemental textbook in science fiction classes, but also contains material of interest to science fiction scholars and others devoted to the genre. In some cases, chapters offer thorough surveys of numerous works involving certain subjects, such as imagined vehicles, journeys beneath the Earth and undersea adventures, discovering intriguing patterns in the ways that various writers developed their ideas. When comprehensive coverage of ubiquitous topics such as robots, aliens and the planet Mars is impossible, chapters focus on major themes referencing selected texts. A conclusion discusses other science fiction subjects that were omitted for various reasons, and a bibliography lists additional resources for the study of science fiction in general and the topics of each chapter.
