physics anyone?

all other sciences branch from physics.

however physics fails to explain what a force is, what an electron, a quark or a gluon is. You may argue, however, that it is philosophy.

physics can't explain anything, they develop a model to explain what is happening, not why, and often not very accurately either.

Not really sure i understand here. Physics can explain these, e.g. a gluon being a gauge boson etc etc etc, but may possibly struggle with where they came from, but obviously that is a philosophical issue yes.

Maybe I should have put the 'fundamental level' in italics. I'm talking about quarks and gluons, fields (not the grassy kind) and forces, which are more fundamental then a cell, however tiny that cell is, although fundamental entites don't necassarily have to be small.

Dont get into metaphysics. Ever. It's the most pointless, yet mentally excruciating thing ever!

Now or ever. I'm quite happy not knowing what an electron is, so long as I know what it does

yeah, that's the whole problem of 'meta'-physics, it being beyond-physics - not saying everything beyond physics is guess work, you can still use logic, the only problem is that logic as we know it might just not work when it comes to that kind of thing - maybe not totally pointless to think about it, but pretty pointless

I thought the only reason it was called metaphysics is because Aristotle wrote it after he wrote his physics.
