Gregory L. Baker was born in Toronto, Canada, and educated primarily in Canadian schools. He received his Doctorate in physics from the University of Toronto in 1970. Moving to the Huntingdon Valley area of Southeastern Pennsylvania, Gregory began his almost four decade career as a professor of physics and mathematics at Bryn Athyn College of the New Church. This volume contains almost the entirety of Dr. Baker's published papers (exclusive of his books). For completeness, it also includes those co-authored with colleagues. Beginning with publications supporting his Ph.D. work, this collection comprises scientific, philosophic, and religious areas, as well as more personal statements addressed to students and public recollections of colleagues and friends. from back cover
