Exploring Black Holes, by E.F. Taylor and J.A. Wheeler, is a neat intro to GR without any tensor calculus.
Jeffrey Marque, a teacher, physicist, and musician currently living in San Mateo, California, began helping students during his undergraduate career, when he tutored high school students. In the early ’70’s, while working as a Staff Research Associate at the University of California at San Francisco (UCSF), Jeffrey Marque organized courses at UCSF centered on mountaineering medicine after he read James Wilkerson’s text Medicine for Mountaineering. Later, in graduate school, Jeffrey Marque served as a Teaching Assistant at the University of Illinois at Urbana-Champaign and at San Francisco State University. In 1988, after completing a post-doctoral appointment at Cornell University, Jeffrey Marque taught classical mechanics and electricity & magnetism courses at the University of San Francisco. In the early 1990s, he served the College of San Mateo, where he taught a beginning physics course during the college’s summer evening sessions. In addition to his work in teaching, Jeffrey Marque acted as Senior Staff Physicist at the Palo Alto, California-based Spinco Division of biomedical instrumentation company Beckman Coulter, Inc. He conducted research in the use of sedimentation-diffusion simulations in the control of rotor speed in ultracentrifuges there, and two of his findings became patented in the United States. In addition, his work was published in the journal Biophysical Chemistry and presented at an American Society of Mechanical Engineers-sponsored Bioprocess Engineering Symposium in Breckenridge, Colorado. After Beckman announced plans to relocate its centrifugation development operation to Indianapolis, Indiana, Jeffrey Marque joined the Marine Systems division of Northrop Grumman Corporation, serving as Lead Simulation Engineer. He holds membership in the American Physical Society and the Institute of Noise Control Engineering, an organization that promotes engineering solutions to excessive acoustical noise in a variety of applications. Jeffrey Marque believes in giving back to his community, and has volunteered with his local food bank in Sunnyvale, California, along with fellow colleagues from Northrop Grumman. He has also donated his time to the Interfaith Hospitality Network, an organization committed to helping needy families find housing. As a donor to Old First Concerts in San Francisco, Jeffrey Marque supports a year-round concert series that feature a wide array of accomplished musicians. A musician himself, Jeffrey Marque was awarded a scholarship to study chamber music at the San Francisco Conservatory of Music during the 1975-1976 academic year. When he has time for leisure, he enjoys riding his bike, hiking, listening to music, and reading.
