休 D.杨（Hugh D.Young） is Emeritus Professor of Physics at Carnegie Mellon Universityin Pittsburgh，PA.He attended Carnegie Mellon for both undergraduate and grad-uate study and earned his Ph.D.in fundamental particle theory under the direction 0f the late Richard Cutkosky.He joined the faculty of Carnegie Mellon in 1956 and has also spent two years as a Visiting Professor at the University of Califomia at Berkeley. Pro Young’S career has centered entirely around undergraduate education.He has written several undergraduate-level textbooks，and in 1 973 he became aCO-authorwithFrancis Sears andMarkZemanskyfortheirwell-knownintroduc-tory texts.witIl their deaths，he assumed full responsibility for new editions 0fthese books until joined by Prof.Freedman for Uiversity Physics. Prof.Young is an enthusiastic skier,climber,and hiker.He also served for sev.eral years as Associate Organist at St.Paul’S Cathedral in Pittsburgh，and hasplayed 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 counthern of southern Utah. 罗杰 A.弗里德曼（Roger A Freedman） is a Lecturer in Physics at the University of California，Santa Barbara.Dr.Freedman was an undergraduate at the University of Califor.nla campuses In San Diego and Los Angeles，and did his doctoral research in nuclear theory at Stanford University under the direction of Professor J.Dirk Walecka.He came to UCSB in 1981 after three years teaching and doing research at the University of Washington. At UCSB，Dr.Freedman has taught in both the Department of Physics and the College of Creative Studies，a branch of the university intended for highly gifted and motivated undergraduates.He has published research in nuclear physics.ele.mentary particle physics，and laser physics.In recent years，he has helped todevelop computer-based tools for learning introductory physics and astronomy. When not in the classroom or slaving over a computer,DL Flreedman can befound either flying（he holds a commercial pilot'S license）or driving with hiswife，Caroline，in their 1960 Nash Metropolitan convertible.
