Understanding the Universe (eBook, PDF)

An Introduction to Physics and Astrophysics

• Format: PDF

Produktbeschreibung

Intended for undergraduate non-science majors, satisfying a general education requirement or seeking an elective in natural science, this is a physics text, but with the emphasis on topics and applications in astronomy. The perspective is thus different from most undergraduate astronomy courses: rather than discussing what is known about the heavens, this text develops the principles of physics so as to illuminate what we see in the heavens. The fundamental principles governing the behaviour of matter and energy are thus used to study the solar system, the structure and evolution of stars, and the early universe. The first part of the book develops Newtonian mechanics towards an understanding of celestial mechanics, while chapters on electromagnetism and elementary quantum theory lay the foundation of the modern theory of the structure of matter and the role of radiation in the constitution of stars. Kinetic theory and nuclear physics provide the basis for a discussion of stellar structure and evolution, and an examination of red shifts and other observational data provide a basis for discussions of cosmology and cosmogony.

Autorenporträt

Intended for undergraduate nonscience majors satisfying a general, education requirement or seeking an elective in natural science, the text examines physics, but with a different perspective from most undergraduate astronomy courses: developing the principles of physics to illuminate the things we see in the heavens. The fundamental problems of the behavior of matter and energy are thus used to study the solar system, the structure and evolution of stars, and the early universe.

Rezensionen

From the reviews "This excellent text on physics is intended for undergraduate non-science majors. It is a unique introductory physics book in the sense that its emphasis is on applications in astronomy ... This kind of well-written and compelling text is the best publicity for the physical sciences! Even science majors and physicists (especially teachers) should read it and enjoy (at least the reviewer enjoyed it a lot)." Mathematical Reviews
