Poultry are a major source of valuable high-quality protein for much of the world's population, so food security is heavily dependent on maintaining poultry health. They are also increasingly important as specialist hobby animals in back-yard flocks. Despite this, veterinarians specializing in the care and health of these important domestic animals are few and far between, and many vets in small animal practice have little real experience of poultry health management and disease. Providing...

The Earth's climate system depends entirely on the Sun for its energy. Solar radiation warms the atmosphere and is fundamental to atmospheric composition, while the distribution of solar heating across the planet produces global wind patterns and contributes to the formation of clouds, storms, and rainfall. The Sun’s Influence on Climate provides an unparalleled introduction to this vitally important relationship.This accessible primer covers the basic properties of the Ea...

Author and Harvard PhD, Mark D. Jackson, a scientist and university chemistry professor expertly streamlined the complicated subject of chemistry selecting the need-to-know answers for ...

A classic introduction to the story of Earth's origin and evolution—revised and expanded for the twenty-first centurySince its first publication more than twenty-five years ago, How to Build a Habitable Planet has established a legendary reputation as an accessible yet scientifically impeccable introduction to the origin and evolution of Earth, from the Big Bang through the rise of human civilization. This classic account of how our habitable planet was as...

Perhaps the two most important conceptual breakthroughs in twentieth century physics are relativity and quantum mechanics. Developing a theory that combines the two seamlessly is a difficult and ongoing challenge. This accessible book contains intriguing explorations of this theme by the distinguished physicists Richard Feynman and Steven Weinberg. Richard Feynman's contribution examines the nature of antiparticles, and in particular the relationship between quantum spin and statistics. In...

In this well-illustrated text, Kenneth R. Lang explains the life cycle of stars, from the dense molecular clouds that are stellar nurseries to the enigmatic nebulae some stars leave behind in their violent ends. Free of mathematical equations and technical jargon, Lang's lively and accessible text provides physical insights into how stars such as our Sun are born, what fuels them and keeps them bright, how they evolve and the processes by which they eventually die. The book demonstrates th...

Make the leap from introductory to organic chemistryThe transition from first-year chemistry to an organic chemistry course can be a challenge for many students. Not only must they recall their first-year studies of bonding, structure, and reactivity, but they must also master a whole new set of nomenclature, along with the critical skill of "electron-pushing." Reviewing the fundamentals and carefully introducing the important new concepts, The Bridge to Organi...

This is a comprehensive and richly illustrated textbook on the astrophysics of the interstellar and intergalactic medium--the gas and dust, as well as the electromagnetic radiation, cosmic rays, and magnetic and gravitational fields, present between the stars in a galaxy and also between galaxies themselves.Topics include radiative processes across the electromagnetic spectrum; radiative transfer; ionization; heating and cooling; astrochemistry; interstellar dust; fluid dynamics, in...

A gripping first-person account of how scientists came to understand our universe's mysterious structureJ. Richard Gott was among the first cosmologists to propose that the structure of our universe is like a sponge made up of clusters of galaxies intricately connected by filaments of galaxies—a magnificent structure now called the "cosmic web" and mapped extensively by teams of astronomers. Here is his gripping insider's account of how a generation of undaunted th...

The breakthrough discovery of an overall logical interpretation of the universe and its universal phenomena supported by findings cumulated over centuries proves that Galilean physics is the only correct physics.

In a thought-provoking and entertaining exploration of The Five Biggest Ideas in Science, authors Charles Wynn and Arthur Wiggins provide a panoramic view of the questions scientists seek to answer about the natural world:* Do basic building blocks of matter exist, and if so, what do they look like?* BIG IDEA #1: Physics' Model of the Atom* What relationships, if any, exist among different kinds of atoms?* BIG IDEA #2: Chemistry's Periodic Law* Where did ...

Galaxies are huge clusters of stars held together by mutual attraction, so as to constitute a system self-gravitating.The discovery of clusters of galaxies is very important from the cosmological point of view, because it helps you learn more about the value of the density of matter in the cosmos. From this value we can determine the curvature of the Universe and its destiny.
