Finding the Light: Science and its Vision explains the development of classical and modern physics, and breakthroughs by a renowned medical research scientist. It explains how modern physics favors realism, over idealism, as the philosophical and ethical foundation of science. It describes growth in Christian faith by eminent scientists. It harmonizes scientific knowledge, philosophical knowledge, and faith, -a divine gift illuminating the mind and heart. Finding the Light orchestrates all these dynamics with lively biographies of Blaise Pascal and Alexis Carrel, celebrated French scientists who fully integrate faith and science in remarkably changed worlds, one living before and the other after the French Revolution. In very few pages Finding the Light is a treasury of scientific, biographical, historical, political, philosophical and religious pedagogy. Its simple, clear, confident storytelling style, reveals a scientist at peace with his life's work and his testimony to the mutual enrichment of science and Christian faith. Dr. James A Cannon (b.1933 - d.2020), after serving in the US Navy during the Korean war, studied and practiced journalism as managing editor of the Fordham University newspaper before switching his area of concentration to physics. He earned an MS at Columbia and a B.S. and Ph.D. at Fordham. He did basic research for Bell Labs but, having the heart of a teacher, left to pursue a career spanning five decades as a revered professor of physics and chemistry at Pace University in New York. A neurological injury led to his retirement. He suffered for a dozen years until complications from Parkinson's and Covid took his life. During this time, with the able assistance of his devoted wife, Monica, Dr. Cannon wrote Finding the Light: Science and its Vision, a culmination his life's work, his Catholic faith, his love of science and his love of teaching.
