Are Particles 'Physical Things' or 'Abstract Ideas'?

[Mudhammam]

Thanks for the thoughtful replies everyone. So, what does the materialism label even mean when the definition of matter, arrived at by physics, is that essentially it's nothing describable beyond ingenious, and almost psychedelic, abstract models... and worse, that it can't yet be made consistent with the world of classical objects!? That's really astonishing when you think about it---the PHYSICAL sciences tackling issues like the basic stuff of matter and space-time and whether or not it has a beginning, or is even fundamental, and realizing that either it's not, or that at bottom it's not remotely physical in a sense anyone can really experience... even in imagination!
