The wave and particle duality of light…

O.K. like I was so not ready for the above question the other night, where the concept of light and its dual nature came up. Looking back, I’m still having a hard time thinking about the best way to talk about it. Partly because I’m still not convinced that it’s one of those things that can be explained in a logical fashion. i.e. it just is – because of variety of different observations suggest that it can exist as either or, or both (depending on how you want to phrase the diction). Mind you, I say this as a geneticist, a science person as far removed as a physicist could possibly be.

Maybe this video can shed light on the strangeness of it all?

…or maybe not?
