Undergrad Article on photon wave-particle duality

[physics pfan]

TL;DR

Need feedback on a new take on duality....

We all know that Feynman declared wave-particle duality as the central/only problem of quantum physics.
Not sure how to evaluate a recent publication summary on this topic: https://sciencex.com/news/2020-11-wave-particle-duality-entanglement-customary-pitfalls.html
Would like others take on this; it come from a different perspective for sure...

I briefly looked at it.
It used the famous equation E = mc² for photons. This is not correct since photons have energy but not mass. The full energy equation is longer, which for massless particles like photons can be reduced to E = pc.

We do? He did? He certainly said QM is strange, and hard to really understand. But I don't think he was hung up on the wave-particle thing. Perhaps this is just semantics though.

I can safely say that that article is garbage. It's written by someone who has no idea what he's taking about. The author is a philosopher and simply hasn't taken the time to learn and understand physics before writing about it.

Frankly, I just don't understand why people are constantly trying to solve, or explain, wave-particle duality in light. We use lots of analogies in teaching physics, which are useful, but, of course, not really correct. We teach classical light diffraction with water wave diffraction in high school, for example. Yet no one has a hard time confusing water waves and light. It seems enough to say that photons act like photons, which, BTW, share some features of waves and some of particles.

A skunk is like a cat, but isn't really a cat. Skunks are like dogs, but there also not completely like dogs. Yet we don't seem to have a cat-dog duality problem with skunks.

Or, something like a "father-accountant" duality, where a man behaves like a "father" when he's at home and like an "accountant" when he's at work.

If I remember correctly he said something along those lines about the double-slit experiment, not the (now a bit outdated) concept wave/particle duality.

 

[vanhees71]

A bit outdated? Well, it's no longer part of physics since 1925, nearly 100 years ago. I'd say it's a shame that "wave-particle duality" is not yet forgotten (as should be also "relativistic mass")!

No, "we all" do not know this.

The OP question is based on a misconception and an invalid reference. Thread closed.
