Philip Gillett person
Philip Gillett, the original author of this text, was born November 21, 1927, in a log cabin in Oregon. His father "rode fence" as an Idahoan rancher, so the West was in Philip Gillett's blood. Gillett claimed his three greatest passions were mountains, music, and mathematics.
Gillett studied physics and mathematics at the University of Wisconsin, receiving his PhB (Baccalaureus Philosophiae, which involved considerable research) and his master's degrees and completing 3 years towards his doctorate. After completing military service, Gillett served as professor of mathematics for over 40 years at the University of Wisconsin, although he returned as often as he could to Colorado and the Rocky Mountains. In addition, he taught in Wisconsin prisons and at the University of Shah Alam in Malaysia.
Gillett published several texts valued in his professional field that covered college algebra and trigonometry, calculus, linear algebra, and differential equations. BVT Publishing has updated Calculus, 6e, with the contribution of a team of authors.
As a lifelong hiker and resident of Rocky Mountain National Park, Gillett's familiarity with its trails, lakes, and peaks (having climbed Longs Peak 37 times, his last ascent when he was in his mid-70s!) led him to publish A Hiking Guide to Rocky Mountain National Park. Gillett's humorous guide, written for hikers at various levels of ability and experience, officially documents over 100 of his favorite lunch spots, often shared with family and friends. "Harden your candy bar in the cold water, submerge your beverage, and settle down for lunch," reads his commentary on Dream Lake. As for music, Gillett maintained a 300-page index of his CDs, and amazingly, listened to them all.
Philip Gillett, his wit at its finest on the trail, touched the lives of thousands of students with whom he shared his understanding and love of mathematics. He died peacefully in his home in Estes Park, Colorado, July 13, 2012, surrounded by family.
Bruce Legan person
Dr. Bruce Legan earned a PhD in mathematics at Kansas State University. Dr. Legan's doctoral research area is in orthomodular lattice (OML) theory. OMLs first arose in the study of quantum physics and its associated quantum logic. Dr. Legan studied OMLs with his advisor, Dr. Richard Greechie, who started OML theory while studying under Dr. David Foulis. Dr. Legan has taught all levels of mathematics for over 35 years.
Lois Thur person
Dr. Lois Thur was born in Nebraska and raised in Iowa and Wisconsin. She earned her BA in secondary education from Concordia University Chicago and her MS and PhD in mathematics from Iowa State University. Since 1994, Dr. Thur has been teaching courses from basic mathematics through calculus and advanced algebra at schools such as University of Montevallo in Alabama, University of Wisconsin in Milwaukee, Concordia University in St. Paul, and the University of Minnesota. She is currently teaching at Century College in White Bear Lake, Minnesota.
Delphene Simpson person
Delphene Simpson earned her bachelor's degree in mathematics from Jadavpur University, India, and master's degrees in mathematics and statistics from the University of Sourthern Mississippi, Hattiesburg, and the University of Kentucky, Lexington. Professor Simpson has over 20 years of experience teaching mathematics and statistics, including teaching courses at Rasmussen College and the University of Minnesota. She and her husband, Dinkar Mylaraswamy, live in Fridley, Minnesota.
Tom Nestor person
James Gamble person
James W. Gamble holds degrees in chemical engineering from Washington University in St. Louis and in chemistry from St. Olaf College in Northfield, Minnesota. He began his career by working primarily in the air and water filtration industry, but he later discovered his love for tutoring and teaching math and science, which he has been doing since 2009. Mr. Gamble is currently a math and science teacher at Groves Academy in St. Louis Park, Minnesota.
David Radcliffe person
Dr. David Radcliffe is an independent software developer living in St. Paul, Minnesota. He has taught mathematics classes at the University of Minnesota, Century College, and also at Inver Hills Community College. David received a BS in mathematics from the University of Wisconsin-Madison and a PhD in mathematics from the University of Wisconsin-Milwaukee.
