Students will be introduced to the science of physics, and its applications to everyday life, in this volume. Tracing its development from antiquity to the present, the author examines all aspects of physics including motion, work, energy, heat, matter, light, and electricity. Quantum & Nuclear physics are also included.
The concept of multiple unperceived dimensions in the universe is one of the hottest topics in contemporary physics. It is essential to current attempts to explain gravity and the underlying structure of the universe. The Great Beyond begins with Einstein's famous quarrel with Heisenberg and Bohr, whose theories of uncertainty threatened the order Einstein believed was essential to the universe, and it was his rejection of uncertainty that drove him to ponder the existence of a fifth dimension. Beginning with this famous disagreement and culminating with an explanation of the newest brane approach, author Paul Halpern shows how current debates about the nature of reality began as age-old controversies, and addresses how the possibility of higher dimensions has influenced culture over the past one hundred years.
Nuclear physics investigates the properties and behavior of the central portion, or nucleus, of the atom. This branch of physics had perhaps the biggest impact on the world in the 20th century because it evolved into the knowledge used to build the most destructive weapons people have ever known. The atomic bombs that ended World War II, and the weapons race that followed, changed the course of history. But applications of nuclear physics have also provided enormous energy for useful purposes, generating about 16 percent of the world's electricity.
Do you ever wonder why it seems like you are not moving even though you are standing on a planet that moves through space? How does matter turn into energy? From Lavoisier to Einstein, Planck, and Bohr, the basic principles of modern physics are revealed in an exciting and appealing way.
.The book concentrates on the conceptual principles of each branch of physics and shows how they fit together to form a coherent whole. Emphasis is placed on the use of variational principles in physics, and in particular the principle of least action, an approach that lies at the heart of moderntheoretical physics, but has been neglected in most introductory accounts of the subject.
The Physics Companion, 2nd Edition offers a unique and educational approach to learning physics at a level suitable for first-year science students. This new edition expands the presentation to include senior topics, such as statistical mechanics, quantum physics, and nuclear physics.
Physics Demystified,helps you grasp the essential concepts with ease. Written in a step-by-step format, this practical guide begins by covering classical physics, including mass, force, motion, momentum, work, energy, and power, as well as the temperature and states of matter. Electricity, magnetism, and electronics are discussed as are waves, particles, space, and time. Detailed examples, concise explanations, and worked problems make it easy to understand the material, and end-of-chapter quizzes and a final exam help reinforce learning.
