Following one of the most inspiring and fascinating stories linked to the Royal Observatory, Greenwich, this book centres on the life and achievements of John Harrison - designer and builder of the first accurate marine chronometers. Inspired by the official prize offered in 1714 to anyone who could solve the problem of finding longitudinal position at sea, Harrison produced his four famous 'H' timepieces. In doing so, he helped revolutionise sea travel, saving many thousands of lives. John Harrison and the Quest for Longitude is the intriguing account of one man driven by the need to solve one of the greatest practical problems of his time.

Informed by astronomy education research, the Sixth Edition reflects an emphasis on learning by doing. This emphasis is reinforced through thoughtful pedagogy and an innovative teaching and learning package. Students get to interact with astronomy while instructors receive the resources they need to incorporate active learning into the classroom.

Die skrywer se doelstelling met hierdie publikasie is om die beginsels van sterrekunde toeganklik te maak vir almal, om ‘n teks daar te stel wat bruikbare toeligting vir die amateursterrekundige is en kan dien as voorbereiding vir verdere studie in die sterrekunde.

Van Zyl se eenvoudige, onderhoudende skryfstyl dra verder by tot die boek se toeganklikheid vir sterrekundiges sowel as leke met ‘n besondere belangstelling in die heelal. Deurgaans word gepoog om te verduidelik hoe sterrekundiges te werk gaan. Om begrip te vergemaklik, verskyn ook 11 bladsye bylaes waarin die wiskunde wat gebruik word uit grondbeginsels herlei word. Dit bevat gedetailleerde beskrywings en verduidelikings van die heelal se geheime.

Inligting oor nuwe ontdekkings en teoriee, kleurvolle diagramme en foto’s verhoog die waarde.

Does science deny God? Did the Universe and life appear by chance or is there evidence of a bigger scheme of thing behind them? In this context, I am concerned with answering these questions. This problem is addressed using knowledge in cosmology, physics and biology. The initial part describes the stages of the 'Genesis' according to physical cosmology from the Big Bang to the appearance of life on Earth. It will touch on problems of why the universe is dominated by matter, the theory of inflation, the limits of our knowledge on the early Universe, the lack of a theory that can allow us to study the phases immediately after the Big Bang, the relation between the concepts of quantum mechanics and the existence of God. It shows how the Universe is finely regulated, that is, the physical constants have been chosen so that life appears in the Universe. The regulation is so strong that we are forced to think the existence of a great designer who has created a particular Universe like the one we are observing. This conclusion can be avoided only if there is an infinity of universes, a multiverse. We ask ourselves if science can create the Universe from nothing and using the same arguments of cosmologists such as Krauss (author of The Universe from Nothing). It is now known that the current science does not allow the creation of a Universe from absolutely nothing. Physics and cosmology do not deny God. Indeed, the argument of the fine adjustment of constants is strongly indicative of the existence of a great designer. Other evidence confirming this comes from biology. Thousands of experiments in recent decades highlight the impossibility of generating life in the laboratory. There is an intrinsic order in life encoded in DNA that is not present in experiments. Simple calculations show that the 'blind and aimless' evolution described by neo-Darwinists such as Dawkins does not allow the generation of life.

Learn about the Earth and the Moon with this engaging science reader. With easy-to-read text, this book teaches students important scientific concepts and vocabulary including the phases of the Moon, the movement of the Earth around the sun, and the rotation of the Earth. Aligned to state and national standards, the book contains nonfiction text features like an index, a glossary, captions, bold font, and detailed images to keep students connected to the text. A hands-on science experiment helps students apply what they have learned and develops critical thinking skills.

Aimed at the senior undergraduate and graduate level, this textbook fills the gap between general introductory texts offering little detail and very technical, advanced books written for mathematicians and theorists rather than experimentalists in the field.
The result is a concise course in atmospheric radiative processes, tailored for one semester. The authors are accomplished researchers who know how to reach their intended audience and provide here the content needed to understand climate warming and remote sensing for pollution measurement. They also include supplementary reading for planet scientists and problems.
Equally suitable reading for geophysicists, physical chemists, astronomers, environmental chemists and spectroscopists.
A solutions manual for lecturers will be provided on www.wiley-vch.de/supplements.

From renowned physicist Fred Alan Wolf comes his enthralling and accessible exploration of parallel universes and the various theories surrounding them.In this "enthralling read" (Publishers Weekly), travel through the frontiers of space as physicist Fred Alan Wolf guides you through the complex yet intruging concept of parallel universes. Challenge your preceptions of the universe and explore ideas as varied as superspace theater and zero-time ghosts and even explore a future where time travel is real and black holes are gateways rather than endings.

The universe is pervaded by particles with extreme energies, millions of times greater than we can produce on Earth. They have been a mystery for over a century. Now, current and future experiments in particle astrophysics are leading us to answers to the most fundamental questions about them. How does nature accelerate the highest energy particles in the universe? Do new interactions between them occur at such extreme energies? Are there unknown aspects of spacetime that can be uncovered by studying these particles?This book brings together three fields within 'extreme astronomy': ultra-high-energy cosmic ray physics, neutrino astronomy, and gamma-ray astronomy, and discusses how each can help answer these questions. Each field is presented with a theoretical introduction that clearly elucidates the key questions scientists face. This is followed by chapters that discuss the current set of experiments - how they work and their discoveries. Finally, new techniques and approaches are discussed to solve the mysteries uncovered by the current experiments.
