Behold the most heartwarming physics reconciliation in history! Newton, the gravity guy, insisted light was made of particles (corpuscles) back in the 1600s. Then along came wave theory, and everyone thought Newton got it wrong. Fast forward to Einstein's photoelectric effect paper in 1905, where he proved light actually DOES behave like particles (photons)! It's the ultimate scientific vindication from beyond the grave! Newton's ghost is somewhere doing a particle victory dance while shouting "I TOLD YOU SO!" through the quantum foam. The ultimate plot twist? Light is BOTH a wave AND a particle. Talk about having your apple and eating it too!
