I believe you are already aware of the problem - you yourself have commented on it before.
I see a computer before me. let us assume that I know nothing of how a computer works. after some short time, I will probably understand that the letters appearing on the screen are caused by me typing on the keyboard. I understand as a modern person living in the era of science that the computer probably works by the laws of physics. but knowing all that, will I be correct assuming that I *understand* how letters appear on the screen when I press the keyboard?
Now, pressing on the keyboard are the neurons and the relations between brain zones and the voltage levels. my conception of the color red is more or less the letters appearing on the screen. surely we cannot ignore the intriguing and curious problem at hand?

To equate two sides of an equation which are dimensionally inconsistent, with a suitable comment to the effect of, "Well, we are interested in the order of magnitude anyway."

I'm quite amazed by this personality recognition capability. Could you distinguish the anonymooses I've used to this day (or atleast recently)?
