Celestial Mechanics


Book Description

The aim of this book is to demonstrate to a wider audience, as well as to a more skilled audience, the many fascinating aspects of modern celestial mechanics. It sets out to do this without the use of mathematics. After giving the reader the technical tools needed for a basic understanding of the underlying physical phenomena (using only elementary mathematics), facts and figures are provided on historical events, modern discoveries and future applications. Contents are divided into major topics where the three "souls" of modern celestial mechanics (dynamical systems, Solar System and stellar systems, spaceflight dynamics) play a major role.




Weird Worlds


Book Description

“Weird Worlds” is the third book in David Seargent’s “Weird” series. This book assumes a basic level of astronomical understanding and concentrates on the “odd and interesting” aspects of planetary bodies, including asteroids and moons. From our viewpoint here on Earth, this work features the most unusual features of these worlds and the ways in which they appear “weird” to us. Within our own Solar System, odd facts such as the apparent reversal of the Sun in the skies of Mercury, CO2-driven fountains of dust on Mars, possible liquid water (and perhaps primitive life!) deep within the dwarf planet Ceres, and a variety of odd facts about the planetary moons are all discussed. A special chapter is devoted to Saturn’s giant moon Titan, and its methane-based weather system and “hydrological” cycle. This chapter also includes recent speculation on the possibility of methane-based organisms and the form that these might take, if they really do exist. Beyond our Solar System, the book looks at the range of worlds discovered and hypothesized. In “Weird Worlds,” the author discusses planets where temperatures are so high that it rains molten iron, and others so cold that liquid methane floods across plains of ice! Worlds are described where the lightest element acts like a metal and where winds blow at thousands of miles per hour – as well as possible planets whose orbits are essentially parabolic. In keeping with previous titles in David Seargent’s “Weird” series, “Weird Worlds” contains several projects that astronomers of all levels can undertake.




Satellite


Book Description

A teenage boy born in space makes his first trip to Earth in this engrossing sci-fi adventure for fans of The Martian from award-winning author Nick Lake. He’s going to a place he’s never been before: home. Moon 2 is a space station that orbits approximately 250 miles above Earth. It travels 17,500 miles an hour, making one full orbit every ninety minutes. It’s also the only home that fifteen-year-old Leo and two other teens have ever known. Born and raised on Moon 2, Leo and the twins, Orion and Libra, are finally old enough and strong enough to endure the dangerous trip to Earth. They’ve been “parented” by teams of astronauts since birth and have run countless drills to ready themselves for every conceivable difficulty they might face on the flight. But has anything really prepared them for life on terra firma? Because while the planet may be home to billions of people, living there is more treacherous than Leo and his friends could ever have imagined, and their very survival will mean defying impossible odds.

From Quarks to Black Holes


Book Description

This book presents a series of delightful interviews in which natural objects such as an electron, a black hole, a galaxy, and even the vacuum itself, reveal their innermost secrets ? not only what they are but also how they feel. A hydrogen atom tells us about quantum mechanics and why we live in a non-deterministic world; a black hole explains curved space and naked singularities; and a uranium atom talks of its life on a meteor, its tremendous collision with Earth, and properties of radioactivity ? all while grappling with its own mortality. A neutron star gives a personal account of its creation and goes on to discuss quasars and other extraordinary astronomical objects, while an iron atom describes its birth in a remote supernova explosion and its series of adventures on Earth, from its early use in wrought iron processes to its time in a human body, and then to its latest misadventures.The book discusses many fundamental issues in physics and, at times, examines the philosophical and moral issues of society. For example, the interview with the quark reveals the nature of color gauge symmetry, which is interwoven with a discussion on truth and beauty, and shows how these concepts play an integral part in physics and nature, while the uranium atom expresses its horror of the development and use of the atomic bomb.

Goodbye, Friend! Hello, Friend!


Book Description

From the creator of The Rabbit Listened comes a gentle story about the difficulty of change . . . and the wonder that new beginnings can bring. Change and transitions are hard, but Goodbye, Friend! Hello, Friend! demonstrates how, when one experience ends, it opens the door for another to begin. It follows two best friends as they say goodbye to snowmen, and hello to stomping in puddles. They say goodbye to long walks, butterflies, and the sun...and hello to long evening talks, fireflies, and the stars. But the hardest goodbye of all comes when one of the friends has to move away. Feeling alone isn't easy, and sometimes new beginnings take time. But even the hardest days come to an end, and you never know what tomorrow will bring.
