University Physics with Modern Physics, 12th International edition--------------------------------------------------University Physics with Modern Physics, Twelfth Edition continues anunmatched history of innovation and careful execution that was establishedby the bestselling Eleventh Edition. Assimilating the best ideas fromeducation research, this new edition provides enhanced problem-solvinginstruction, pioneering visual and conceptual pedagogy, the first systematicallyenhanced problems, and the most pedagogically proven and widely usedhomework and tutorial system available. Using Young & Freedman's research-basedISEE (Identify, Set Up, Execute, Evaluate) problem-solving strategy,students develop the physical intuition and problem-solving skillsrequired to tackle the text's extensive high-quality problem sets,which have been developed and refined over the past five decades. Incorporatingproven techniques from educational research that have been shown toimprove student learning, the figures have been streamlined in colorand detail to focus on the key physics and integrate 'chalkboard-style'guiding commentary. Critically acclaimed 'visual' chapter summarieshelp students to consolidate their understanding by presenting eachconcept in words, math, and figures. Renowned for its superior problems,the Twelfth Edition goes further. Unprecedented analysis of nationalstudent metadata has allowed every problem to be systematically enhancedfor educational effectiveness, and to ensure problem sets of idealtopic coverage, balance of qualitative and quantitative problems, andrange of difficulty and duration. If a professor adopts MasteringPhysicsTM,every new copy of the text includes access to it -- the most widelyused, educationally proven, and technically advanced tutorial and homeworksystem in the world. Uniquely able to tutor each student individuallywith feedback specific to their errors and simpler subproblems upondemand, MasteringPhysicsa now incorporates free-hand graphs, free-bodydiagrams, ray-tracing diagrams, even ranking-task activities. MasteringPhysicsaprovides all the problems from the text as well as tutorials specificto the Problem-Solving Strategies and Test Your Understanding questionsin each chapter.--------------------------------------------------Author Biography: Hugh D. Young is Emeritus Professor of Physics atCarnegie Mellon University in Pittsburgh, PA. He attended CarnegieMellon for both undergraduate and graduate study and earned his Ph.D.in fundamental particle theory under the direction of the late RichardCutkosky. He joined the faculty of Carnegie Mellon in 1956 and hasalso spent two years as a Visiting Professor at the University of Californiaat Berkeley. Prof. Young's career has centered entirely aroundundergraduate education. He has written several undergraduate-leveltextbooks, and in 1973 he became a co-author with Francis Sears andMark Zemansky for their well-known introductory texts. With their deaths,he assumed full responsibility for new editions of these books untiljoined by Prof. Freedman for University Physics. Prof. Young isan enthusiastic skier, climber, and hiker. He also served for severalyears as Associate Organist at St. Paul's Cathedral in Pittsburgh,and has played numerous organ recitals in the Pittsburgh area. Prof.Young and his wife Alice usually travel extensively in the summer,especially in Europe and in the desert canyon country of southern Utah.Roger A. Freedman is a Lecturer in Physics at the University ofCalifornia, Santa Barbara. Dr. Freedman was an undergraduate at theUniversity of California campuses in San Diego and Los Angeles, anddid his doctoral research in nuclear theory at Stanford Universityunder the direction of Professor J. Dirk Walecka. He came to UCSB in1981 after three years teaching and doing research at the Universityof Washington. At UCSB, Dr. Freedman has taught in both the Departmentof Physics and the College of Creative Studies, a branch of the universityintended for highly gifted and motivated undergraduates. He has publishedresearch in nuclear physics, elementary particle physics, and laserphysics. In recent years, he has helped to develop computer-based toolsfor learning introductory physics and astronomy. When not in the classroomor slaving over a computer, Dr. Freedman can be found either flying(he holds a commercial pilot's license) or driving with his wife, Caroline,in their 1960 Nash Metropolitan convertible. A. Lewis Ford is Professorof Physics at Texas A&M University. He received a B.A. from Rice Universityin 1968 and a Ph.D. in chemical physics from the University of Texasat Austin in 1972. After a one-year postdoc at Harvard University,he joined the Texas A&M physics faculty in 1973 and has been thereever since. Professor Ford's research area is theoretical atomic physics,with a specialization in atomic collisions. At Texas A&M he has taughta variety of undergraduate and graduate courses, but primarily introductoryphysics.
