You know, I just smoked a little bowl and i was thinking about this and I had one of those thoughts that you sometimes get when you're stoned and you figure that later you'll see -- in the clear logic of the unstoned state -- that the thought you had was retarded. But I'm going to put it out here anyway, and hopefully we're all about equally stoned and it won't sound stupid. At any rate, somewhere here in the Forum one of the experts was saying that plants use light spectra in the blue and red zones, and the spectrum that they don't use is the green, hence their green color. They absorb everything except the green, which they reflect, which is why we can see it. (My girlfriend just walked by with no cloths on. She says I shouldn't get stoned today since we have things to do, but I figure that I can do both. She also says I shouldn't get stoned since it makes me forgetful and I lose my focus and train of thought, but that's ridiculous.)
Now, what was I talking about? Oh, yeah,... I was thinking about this: if plants only reflect green, what would happen if you had one of the Professeur's pure blue bulbs, turned all other lights out, and then turned the blue one on. Would you be able to see the plants?
Anyway, with a naked girl in the room I just decided that this idea no longer has any interest for me, but I've pretty much typed the whole thing so I might as well post it.
All the best, Bob
