What Every Christian Should Know about Quantum Mechanics



[Fresh religious insights are often found by reference to the language and metaphors of other disciplines, especially the sciences. St. Andrew's Church in Framingham, Mass., recently hosted such a cross-disciplinary "fertilization" opportunity, led by Network member Paul Bamberg, Senior Lecturer on Mathematics, Harvard University. He has kindly provided us with his notes below, including the caveat.]

Beware: the author is a well-trained physicist and and mathematician but has no credentials in theology. Understand the physics, then draw your own theological conclusions!

Issues to be considered:
  • 1. Quantum mechanics and statements that appear self-contradictory (e.g., waves, particles, and the dual nature of light and matter)
  • 2. What does it mean to "know everything?"

    • Probability in classical physics
    • Probability in quantum physics
    • Does God really "play dice with the universe"?
    • Might God have access to "hidden variables"?
  • 3. Can a system be observed without influencing it?
    • a. The Heisenberg uncertainty principle
    • b. The importance of "indistinguishable alternatives"
Question for discussion: Of the following statements, what do 2) and 3) have in common?
  • 1) Karo syrup is completely colorless and extremely sticky.
  • 2) Jesus Christ was both fully human and fully divine.
  • 3) Light behaves both exactly like a wave and exactly like a particle.
  • 4) Jesus Christ was a devout Jew and a skilled carpenter.

Lecture demonstrations:
  • a. The wave nature of sound: interference between two loudspeakers
  • b. The wave nature of light: Young's double-slit experiment
  • c. The particle nature of light: photoelectric effect
  • d. Random events and particle detection: Geiger counter with beta and gamma sources
  • e. Energy levels: fluorescence of minerals and quinine water
