Solar activity has become of increasing importance in our modern society, as many aspects of today's technology could be affected by eruptive phenomena associated with solar magnetic variability. State of the art solar instrumentation is revealing the dynamics of the Sun with unprecedented temporal and spatial resolutions. This volume includes recent results in solar physics research presented at the IAU Symposium 327, the first IAU symposium held in Colombia, in the historical city of Cartagena de Indias, one of the oldest in the Americas. Its main scientific goal was to discuss recent results on the processes shaping the structure of the solar atmosphere and driving plasma eruptions and explosive events in our star. Researchers in both theory and observation, who study structure and activity in the solar atmosphere, discuss a wide range of topics in the field.

Aimed at engineering students and professionals working in the field of mechanics of space flight, this book examines space tether systems - one of the most forward-thinking directions of modern astronautics. The main advantage of this technology is the simplicity, profitability and ecological compatibility: space tethers allow the execution of various manoeuvers in orbit without costs of jet fuel due to the use of gravitational and electromagnetic fields of the Earth. This book will acquaint the reader with the modern state of the space tether's dynamics, with specific attention on the research projects of the nearest decades. This book presents the most effective mathematical models and the methods used for the analysis and prediction of space tether systems' motion; attention is also given to the influence of the tether on spacecraft's motion, to emergencies and chaotic modes.

A photographic study in Selenography (lunar geology), whereby an attempt is made to determine whether there is evidence for extraterrestrial activity of ET aliens and alien artifacts on the moon and Mars. Illustrated with hundreds of B&W NASA pictures 483 pages.

The chemical elements are all around us, and are part of us. The composition of the Earth, and the chemistry that governs the Earth and its biology are rooted in these elements.

As we enter a new millennium, people the world over are reflecting on the accomplishments of the past and speculating about opportunities of the future. This document discusses human exploration and development of space.

This book is a new look at one of the hottest topics in contemporary science, Dark Matter. It is the pioneering text dedicated to sterile neutrinos as candidate particles for Dark Matter, challenging some of the standard assumptions which may be true for some Dark Matter candidates but not for all. So, this can be seen either as an introduction to a specialized topic or an out-of-the-box introduction to the field of Dark Matter in general. No matter if you are a theoretical particle physicist, an observational astronomer, or a ground based experimentalist, no matter if you are a grad student or an active researcher, you can benefit from this text, for a simple reason: a non-standard candidate for Dark Matter can teach you a lot about what we truly know about our standard picture of how the Universe works.

So much to read, so little time? Get an overview of Hidden Figures, the true story about the African American female mathematicians who helped NASA win the space race. Margot Lee Shetterly's Hidden Figures tells the incredible real-life account of Dorothy Vaughan, Mary Jackson, Katherine Johnson, and Christine Darden--who, in a time when black women faced seemingly insurmountable obstacles, went to work as "calculators" at NASA. With pencils, paper, and slide rules, they transformed airplane, rocket, and satellite designs--and ensured a World War II victory. Despite the social and political climate at the height of Jim Crow, these women rose up and became integral to the project that put the first man on the moon. From World War II to the Cold War to the civil rights movement to the space race, Hidden Figures tells the story of four remarkable women whose contributions to science led to some of NASA's greatest successes. The book has become a New York Times bestseller as well as a Screen Actors Guild Award-winning and Academy Award-nominated picture starring Taraji P. Henson, Octavia Spencer, Kirsten Dunst, and Kevin Costner. With historical context, important quotes, fascinating trivia, a glossary of terms, and other features, this summary and analysis of Hidden Figures: The American Dream and the Untold Story of the Black Women Mathematicians Who Helped Win the Space Race is intended to complement your reading experience and bring you closer to a great work of nonfiction.
