Thank you so much for that! That is actually a really good explanation of what a photon is, at least to a layman like myself. For me anyway, my brain tries to think of a photon as a particle, but thinking about it as a "unit" of light is probably a bit easier.
I'm like you in the sense that I'd prefer to read something than watch a video. Thanks for transcribing that pal, really clears things up for me!
