Natural Order and Science

[Alex K]

Yes, of course the photons are absorbed by the electrons in your eyes, but if you understand the definition, those electrons in your eyes are part of the detector. So by definition, those electrons are not VIRTUAL. You think you understand the basic definition, but you don't.

Oh, so your definition of virtual particles is / contains that they don't interact with the detector? Can you point me to a textbook source or so where this definition is introduced?

BTW, that table of contents, I can teach you every single topic in that table of content. I'm not bragging, I'm just stating a fact.

I will gladly learn something new about quantum field theory from you, but your pompous tone is a bit off-putting. For example, you suddenly elaborated on an entire (and irrelevant) course outline on the topic when the discussion was about what we consider virtual particles. To what end, intimidate me? If you can do what you claim you can do, you have no need for this kind of posturing. Show, don't tell.
