The Sciences: An Integrated Approach, 9th Edition by James Trefil and Robert Hazen recognizes that science forms a seamless web of knowledge about the universe. This text fully integrates physics, chemistry, astronomy, Earth sciences, and biology and emphasizes general principles and their application to real world situations. The goal of the text is to help students achieve scientific literacy. Applauded by students and instructors for its easy-to-read style and detail appropriate for non-science majors, the ninth edition has been updated to bring the most up-to-date coverage to the students in all areas of science, with increased emphasis on climate change, sustainability, viruses and public health, and an extensively updated chapter on the importance of bioengineering. FEATURES INCLUDE: The Science of Life - To help show the interdisciplinary nature of the many concepts introduced in the text, sections on living things are included in most chapters. The chapters that emphasize principles specifically related to life are at the end of the book, but the biological examples appear throughout. The Ongoing Process of Science - Science is a never-ending process of asking questions and seeking answers. In these features, some of the most exciting questions currently being addressed by scientists are examined. Mathematical Equations and Worked Examples -Whenever an equation is introduced, it is presented in three steps: first as a sentence, second as a word equation, and finally in its traditional symbolic form. In this way, students can focus on the meaning rather than the abstraction of the mathematics. An appendix on English and SI units is also included. Science by the Numbers - To help students understand the importance of simple mathematical calculations in areas of magnitude, several nontraditional calculations have been incorporated. For example, how much solid waste is generated in the United States, how long it would take to erode a mountain, and how many people were required to build Stonehenge. Great Ideas and Great Ideas Concept - Each chapter begins with a statement of a great unifying idea or theme in science and a concept map so that students immediately grasp the chief concept of the chapter and how the idea relates to the different branches of science. These statements are intended to provide a framework for placing everyday experiences into a broad context. Stop and Think! Questions challenge students to think critically about the implications of a scientific discovery or principle. Resources for Instructors and Students including practice quizzes, flashcards, lecture slides, an instructor’s manual, images and tables from the book, a test bank, and much more!

Microelectronics is the cornerstone of the information technologies that pervade virtually every aspect of contemporary life. It is difficult to imagine any field of science or technology that has had a more profound impact on the latter half of the 20 century than microelectronics. Microelectronics industry has been able to provide transistors, chips and products that are becoming smaller, faster, cheaper and better every year. As transistors become smaller, they become faster, more and more of such transistors can be packed on a chip, and thus chips are able to store and process more information. Digital circuits are made from analog components. The design must assure that the analog nature of the components doesn't dominate the desired digital behaviour. Digital systems must manage noise and timing margins, parasitic inductances and capacitances, and filter power connections. Bad designs have intermittent problems such as "e;glitches"e;, vanishingly-fast pulses that may trigger some logic but not others, "e;runt pulses"e; that do not reach valid "e;threshold"e; voltages, or unexpected ("e;undecoded"e;) combinations of logic states. A digital circuit is often constructed from small electronic circuits called logic gates that can be used to create combinational logic. Each logic gate represents a function of boolean logic. A logic gate is an arrangement of electrically controlled switches, better known as transistors. Each logic symbol is represented by a different shape. This book is designed for advanced undergraduates and graduate students with background knowledge in basic electronics including biasing, modeling, circuit, analysis, and frequency response.

Work more effectively and gauge your progress along the way! Designed to be used alongside Trefil’s The Sciences, 4th Edition, this Study Guide contains many elements that foster student success. Included are chapter reviews, learning objectives, key chapter concepts and key concept charts. The ties between science and math are reinforced with key formulas and equations. Links to scientists and their findings are outlined to help improve your comprehension of key subject area concepts. The Sciences, 4th Edition integrates major concepts from physics, chemistry, astronomy, earth sciences, and biology to help anyone become science-literate. Even readers with little or no science background will find this unique book an indispensable guide to understanding the latest headlines, controversies, and scientific developments. The new edition keeps pace with the dynamic nature of the sciences by incorporating the most up-to-date discoveries in all five disciplines.

This book explores many fundamental topics in a basic and easy-to-understand manner. It, and the accompanying DC-AC Electrical Fundamentals by the same co-authors, have been developed using a classic textbook – Electricity and Electronics: A Survey (5th Edition) by Patrick and Fardo – as a framework. Both new books have been structured using the same basic sequence and organization of the textbook as previous editions. This book has been expanded to 23 chapters, further simplifying content and providing a more comprehensive coverage of fundamental content. The content has been continually updated and revised through new editions and by external reviewers throughout the years. Additional quality checks to ensure technical accuracy, clarity and coverage of content have always been an area of focus. Each edition of the text has been improved through the following features: Improved and updated text content. Improved usage of illustrations and photos. Use of color to add emphasis and clarify content.
