Reading threads that discuss these topics all seem to have the same problem...everyone wants to contradict everyone else by saying the same thing better or just differently. There is always this big play of words {or lack of using the "best" ones}. It really seems like there is more of a problem with the English language than there is with debating an optical or light related question. The subject of light is confusing enough, but we always have to complicate it further by seeing how many different ways we can describe what is happening.
In example; While discussing camouflage and how animals visually perceive things I was asked what color my house was...when I said it's gray the person, a former professor at UMD said, "no, your house is not gray, the light that you see reflected off your house is seen as gray by your eyes!!!, You believe it is gray because that is the way your eyes perceive the light that is being reflected."
I am sure he is correct, but no one references it this "most correct of ways" any other time...I mean, when was the last time you heard somebody walk in to a paint store and say, "I need paint that will cause the light reflecting off my house to trick my eyes into believing and seeing it as gray....." Doesn't every one of us just say "gimme some gray paint"??? Nobody has to correct this guy for asking....
The only thing I can figure is that it made him feel better to "inform" me how wrong I have been all these years!!! I think he is correct and it can be an interesting way to look at it, but again, at the end of the day who really cares???
I see the same thing in these threads...I guess my question is, if the end result is the same and we all agree for example that when you look thru high quality optics and see way better than you ever could without them, does it really matter if it "gathers" or "delivers" or wait, still another way to say it is "transmits" how about "main lines" or "funnels" or any other way you can say "lets you see better"???
