Photons

The book delves into the evolving concept of 'light quanta' or 'photons', exploring the various interpretations and terminology used by physicists over time. It examines differing mental models, questioning whether these entities are seen as discrete packets of energy, wave-like structures, or particles. The discussion includes historical perspectives and the implications of terms like 'atoms of light' and 'virtual exchange particles', providing a comprehensive overview of the complexities surrounding the nature of light in quantum physics.
