The petroleum age began about 150 years ago. Easily available energy has s- ported major advances in agriculture, industry, transportation, and indeed many diverse activities valued by humans. Now world petroleum and natural gas s- plies have peaked and their supplies will slowly decline over the next 40–50 years until depleted. Although small amounts of petroleum and natural gas will remain underground, it will be energetically and economically impossible to extract. In the United States, coal supplies could be available for as long as 40–50 years, depending on how rapidly coal is utilized as a replacement for petroleum and natural gas. Having been comfortable with the security provided by fossil energy, especially petroleum and natural gas, we appear to be slow to recognize the energy crisis in the U. S. and world. Serious energy conservation and research on viable renewable - ergy technologies are needed. Several renewable energy technologies already exist, but sound research is needed to improve their effectiveness and economics. Most of the renewable energy technologies are in uenced by geographic location and face problems of intermittent energy supply and storage. Most renewable technologies require extensive land; a few researchers have even suggested that one-half of all land biomass could be harvested in order to supply the U. S. with 30% of its liquid fuel! Some optimistic investigations of renewable energy have failed to recognize that only 0. 1% of the solar energy is captured annually in the U. S.
An Introduction to Modern Astrophysics is a comprehensive, well-organized and engaging text covering every major area of modern astrophysics, from the solar system and stellar astronomy to galactic and extragalactic astrophysics, and cosmology. Designed to provide students with a working knowledge of modern astrophysics, this textbook is suitable for astronomy and physics majors who have had a first-year introductory physics course with calculus. Featuring a brief summary of the main scientific discoveries that have led to our current understanding of the universe; worked examples to facilitate the understanding of the concepts presented in the book; end-of-chapter problems to practice the skills acquired; and computational exercises to numerically model astronomical systems, the second edition of An Introduction to Modern Astrophysics is the go-to textbook for learning the core astrophysics curriculum as well as the many advances in the field.
An innovative art program of generously sized illustrations ? each including a key concept statement and review question -- provides a consistent learning environment enabling students to make the connection between text and visual elements. A concise narrative, praised by students for its straightforward and easily comprehensible writing style, emphasizes scientific content over extraneous detail. Exhibits ?specially designed self-contained lessons -- provide students with the extra help needed to learn the numerous structures that constitute certain body systems ? most notably skeletal muscles, articulations, blood vessels and nerves. The duel themes of homeostasis and disruptions to homeostasis are effectively presented through the relevant use of in-chapter applications, end-of-chapter disorder boxes, and end-of-chapter lists of medical terminology. Continued coverage of scientific research and breakthroughs in understanding the human body keep the book on the cutting edge. Carefully integrated learning aids, such as pronunciations, word roots, summary tables, and cross-references complement the readable narrative. An extensive supplements package with aids to facilitate the variety of teaching and learning styles.
