Conceptual Physics, Global Edition (PDF)

Life-changing events occurred inMiami. First, I married Millie. Second, I met sign painter and science buffBurl Grey and his intellectual mentor, Jacque Fresco. Both inspired me topursue a life of science. I returned north and with the G.I. Bill, enrolled atNewman Preparatory School in Boston to make up for high-school deficiencies. Atthe age of 27, I began college at Lowell Technological Institute (now theUniversity of Massachusetts Lowell). After I received a Bachelor of Science degreein physics, Millie and I and our two children ventured west, where I would earna Master of Science degree in physics at Utah State University (USU). There, Iwas inspired by the extraordinary teaching of Farrell Edwards and John J.Merrill. USU friends Huey and Sue Johnson influenced us to follow them to SanFrancisco, where Huey, a passionate environmentalist, began his career as WesternDirector of the famed Nature Conservancy and soon became California's Secretaryof Resources during Jerry Brown's administration. Huey also founded The Trustfor Public Land, an organization that saves tracts of land from unwantedcommercial development, and he later founded the nonprofit Resource RenewalInstitute. Best friend extraordinaire Huey passed away in 2020 fromcomplications after a fall. It was with Huey's assistance in 1964 that I washired as a long-term substitute at City College of San Francisco (CCSF).

My teaching assignment was thecourse least popular among my colleagues, Physics 10, which was geared towardnon-science majors, the very students I wanted to reach. My teaching goal wasnot to swell the ranks of physicists, but to share my love of physics with allstudents. I very soon discovered that the best of my algebraic derivations wereunappreciated. Nor did students think much of my simple problems that usedequations as recipes to come up with numerical answers. My teaching evolved to"physics without numbers," and Physics 10 soon became the mostpopular elective course on campus. I yearned to teach from a new and excitingtextbook, Physics for the Inquiring Mind, by Eric Rogers, but mydepartment chair found it unacceptable because it was too large and heavy forstudents to tote around.

That meant I would have to writemy own book. Inspired by the Rogers book and Basic Physics, a new,clearly written textbook by Kenneth Ford, I frantically spent the summer of1969, the year of the first Moon landing, creating Conceptual Physics.The spiral-bound result was graciously printed on campus by the collegebookstore. Its coverage of topics was in step with my nemesis as a student:information overload. It covered only the fundamentals of physics. It had nonumerical problems requiring even simple algebra. None. As such, it was a quitelocal CCSF book.

Enrollment for Physics 10 hadgrown to more than a thousand per semester. Curious textbook sales representativesthought that Conceptual Physics could be more than a localbook. To make a long and interesting story short, Little, Brown and Companypublished it in 1971 (50 years ago). This was at a time when college studentsnationwide were demanding relevance in their courses. With its subtitle, A New Introduction to Your Environment, ConceptualPhysics was seen as very relevant. To add to the accuracyof the physics, Ken Ford volunteered his editorial pen to my writing. Idedicated the eighth and eleventh editions to him. Conceptual Physics becamethe dominant book for liberal arts physics courses in the United States, andalso internationally.

Teaching was not confined toCCSF. On Wednesday evenings, I taught at the San Francisco Exploratorium. I wasoften honored when founder Frank Oppenheimer sat in on my classes. When musicalsounds was the topic, with his collection of woodwind instruments, Frank didthe teaching, and I sat in. Wonderful times teaching with Frank.

As an author, I never went thecommon route of following an introductory textbook with an algebra/trigonometry-basedbook and then a calculus-based textbook. Instead, I elected to keepimproving Conceptual Physics for non-science students, edition after edition, a continuous strivingto increase the clarity of physics topics, to make physics a course thatstudents could love. For an algebra-based course, Phil Wolf and I wrote aproblem-solving book to supplement Conceptual Physics. It is now animportant complement to this thirteenth edition.

In my personal life, my wifeMillie peacefully passed away in 2004, leaving me with three wonderful childrenand seven well-loved grandchildren. A year later I married Lillian Lee. Both ofmy marriages were to impressive women. Today, my wife Lillian, with her eye fordetail, adds clarity to my writing. Hence, I dedicate this edition to her, as Idid with previous editions.

I never traveled outside of theUnited States until age 40. Since then, summers have been devoted to worldtravel. My teaching took me further afield as well, mainly to the University ofCalifornia at both Berkeley and Santa Cruz, and the two university campuses inHawaii. In Hawaii, I was also invited to teach in a video studio. Little did Irealize that those lectures would remain popular today.

A move from Hilo, Hawaii, to St.Petersburg, Florida, brought me closer to my pal from my roller-skating days,Paul Ryan (pictured in all my books). Lil and I now split our time between St.Petersburg and San Francisco, continually polishing the lens through whichstudents can more clearly view their world. Nature's major rules are revealedin the laws of physics, all nicely summarized in their equations. Teachingthese equations as the rules of nature has been an awesome experience.

More awesome is being born. Thechances of being born a healthy human are so miniscule that being alive is thehighest prize of the universe. But that prize comes with a certainty: beingborn means eventually dying. Before birth, our experience of the universe andall its happenings was blank. With no consciousness, there was nothing. If thatblank state is our fate after death, then there's nothing to fear. Now, ifthere's more, hooray - But there needn't be. Death as the price of birthis a fair cosmic bargain. Along with grieving the loss of loved ones, we shouldcelebrate that they knew life.
