In this ITEST Webinar "Bridging the Chasm: Quantum Mechanics and Christian Spirituality," Dr. Bob Kurland and Dr. Terrence Lagerlund (December 16, 2023) BRIDGING THE CHASM: HOW QUANTUM MECHANICS BRINGS TOGETHER THE PHYSICAL AND SPIRITUAL WORLDS BY TERRENCE D. LAGERLUND, MD, PHD Dr. Terrence Lagerlund has been a neurologist in the Division of Epilepsy at Mayo Clinic for 35 years, treating patients with epilepsy and interpreting their electroencephalograms. He also lectures to residents and fellows on electroencephalography including basic principles of electricity and neurophysiology. He has published papers and authored book chapters on electroencephalography and epilepsy, particularly regarding quantitative analysis of electroencephalograms. Prior to becoming a neurologist, he obtained a Ph.D. in physics and worked as a postdoctoral research associate at the MIT Laboratory for Nuclear Science (doing research at Brookhaven National Laboratory and CERN) and as a term physicist at Fermilab. ABSTRACT The God of Judeo-Christian tradition is the Lord of the universe, and scriptures affirm God’s sovereignty over the course of events. However, the discoveries by Newton and others that the universe is governed by rigid laws of cause and effect that are expressed as mathematical formulas engendered the belief that the universe is a complete, closed system of cause and effect (the principle of “causal closure”), and therefore that God cannot possibly influence or change what happens in the physical universe. In this worldview, God, even if he exists, is irrelevant to our lives, and our souls, even if they exist, are irrelevant to what we believe, say, or do. However, quantum mechanics may provide an opening for the spiritual world to influence the physical. Quantum mechanics (QM) describes physical systems by a state vector (SV), a collection of superimposed possible states. During the quantum to classical transition, possible states reduce to one actual state (SV collapse). QM predicts the probability of each possible outcome. SV collapse seems to be an uncaused process with a random result, breaking the deterministic chain of physical causes and effects. Wolfgang Smith hypothesized that God causes SV collapse and chooses the outcome. TOURING THE WONDERLAND OF QUANTUM MECHANICS BY ROBERT KURLAND, PHD Dr. Robert Kurland (a convert to Catholicism in 1995) is a retired physicist who has applied magnetic resonance to problems of biological interest in his research (web search: “Kurland-McGarvey Equation”). He began to learn about quantum mechanics at Caltech (BS, “with honor,” 1951) and Harvard (MS,1953; Ph.D.,1956) from courses taught by Richard Feynman and Julian Schwinger. In teaching quantum mechanics to students at Carnegie-Mellon University and SUNY/AB he found that mathematical formalism of quantum mechanics was an obstacle to understanding. So, in his talk he will try to explain what quantum mechanics is about using a minimum of mathematics, as he did in his book Mysteries: Quantum and Theological. ABSTRACT The talk will give a brief, qualitative, pictorial explanation of quantum mechanics, from a historical perspective. I’ll illustrate two mysteries of quantum mechanics—superposition of states (the Schrödinger Cat paradox) and entanglement—by use of simple examples. Also, I’ll discuss some of the many interpretations of quantum theory, focusing on how they might be related to Catholic teaching.
