1) Although videos are visual aids by definition, it wasn't suggesting that a human could visualize any dimension except the 1st, 2nd, and 3rd I believe; this is why mathematicians must use numerical expressions (iterated for the nth time on HN) because human cognition is inextricably tied to interpreting perceptual data within the 3D Cartesian plane. 2) It is a youtube video. 3) Node (n-2) of this one was merely suggesting rather matter-of-factly that confusion is a weak conjecture. 4) I really don't disagree on node (n-1) because any spatial dimension can be parametrized possibly dispelling the "4th" part. I'm assuming your beef is that time breaks down in 5D (or 4D depending on who's counting) because it ceases to move in one direction? 5) If the former is true, Poe's Law still holds, and no matter what, I plea the 5th on further comment of this submission other than god forbid an innocent observe this video and enter into the nth dimension with an error margin of +-D. ;)
