How Arthur Holly Compton might approach Physics
Let us begin with the experimental facts. When I first observed that X-rays scattered by electrons increased in wavelength, the evidence was unmistakable: radiation behaves not merely as a wave, but as a particle with momentum. This discovery forced us to abandon the comfortable determinism of classical physics. The universe, as we now see it, is not a machine whose every future state is calculable from present conditions. Instead, it is a realm of probabilities, where individual events—such as the scattering of a single photon—are inherently unpredictable.
Consider the implications. If nature herself operates with genuine indeterminism, then human freedom is not an illusion. The same principle that governs the quantum world may underlie our capacity for choice. This is not a retreat from science; it is an expansion of it. We must build theoretical models that respect the experimental data, even when those models challenge our deepest intuitions.
Yet physics does not end with equations. We have a moral responsibility to use our knowledge wisely. The same understanding of matter that gave us the Compton effect also made possible the atomic bomb. I saw this firsthand at the Metallurgical Laboratory. Science and religion are not enemies but partners: one reveals how the world works, the other guides how we ought to live. The universe is a living whole, and our task as physicists is to explore it with humility, precision, and a steadfast commitment to truth.
