"Viewing a Photon as an Event."
Since its modern inception, about a century ago, a
photon is often visualized as some sort of massless, formless "particle" whizzing through space at the rigorous velocity of 300,000 kilometers per second. Yet, in all this time, no such "particle" has since ever been detained for scrutiny. In fact, to detect a photon is to destroy it; since it can only be detected in the moment that imparts its full energy. Thus there is no bonafied assurance (proof) that the photon exists (as a particle) prior to that moment. And we know it doesn't exist after that moment. All we can be sure of is that it is manifest at the very moment that it imparts its energy.
Neither Max Plank or Einstein, in their analyses of light
quanta, guarantee a particle-like entity at anytime before or after the sudden energy release that accounts for the discrete emission of electrons in Henrich Hertz's 1886 discovery. The idea of a 'photon particle' came along sometime after. It was added--somehow.
So, if we want to be careful in our interpretations of
what we see nature doing--i.e. to be accurate--we might restrict our definition of a photon to the actual, perceived, one-time occurrence that we can attest to. In other words, we might consider a photon as an instantaneous "event"...nothing more.
Photons are classified in the boson family--along with the
short-lived, naturally occurring W- boson. Bosons exhibit properties that are not affected by the Pauli exclusion principal--and, hence, their energies (I think) suggest a potentially smooth continuum in nature. The W- is also considered as a carrier of electromagnetic "force". It is relatively easy to think of the W- boson as an"event" which occurs once and only once. Its emergence might be likened to a nanoscopic "explosion"--or otherwise, an "impulse" in a much larger electromagnetic continuum. So may be true for the photon. |

All these fifty years of conscious brooding have
brought me no nearer to the answer to the question, 'What are light quanta?' Nowadays every Tom, Dick and Harry thinks he knows it, but he is mistaken. (Albert Einstein, 1954) |
