2. The Great Math Mystery

Is math invented by humans, or is it the language of the universe? http://www.pbs.org/wgbh/nova/physics/great-math-mystery.html

My proposition was about a circle as a whole, not each individual point on it. For example, let P1 denote the point at 11:00 o’clock on the circle before movement. There is a point P2 at 11:00 o’clock on the circle after movement. A vector drawn from P1 to P2 is parallel to, and the same length as, the center's translation vector. Like I said, this is true independent of any rotation, slipping, or skidding. If the circle is rotated exactly 0, 1, 2, 3, …. times – which is true for Aristotle’s wheel paradox -- then the vector from P1 to P2 is P1's translation vector, and every point on the circle moves the same distance translation-wise. Since I will have so little free time the next several weeks, it’s time for another long hiatus.

The Millstone Jonathan and Bubba went for a stroll. They discover an old millstone shaped like this one. They measured the diameter and hole. The diameter was 50 inches and the square hole was 10 inches on each side. Despite its great weight they somehow managed to roll it one rotation, a distance of approximately157 inches. Bubba: Isn’t that a paradox? We moved the millstone 157 inches. However, the hole rotated only once and its perimeter is only 40 inches. How did that happen? Jonathan: It slipped. Bubba: What are you talking about? Jonathan: The supporting rail a fraction of an inch below the hole. Didn’t you see the hole slip on it, idiot? Didn’t you hear the screeching and grinding of friction from the hole on the rail, nitwit? Do I need to make one of my illustrious animated videos with sound effects to prove it to you, stupid? Bubba: I didn’t see or hear any such thing. Jonathan: Then you are visually and aurally retarded!! Hahahaha.

Prove that when my car’s 4 tires roll on a real road, there exists another parallel, invisible surface tangent to the bottom of the metal rim of each wheel. Also, the rim really rolls on, slips on, and is really supported by said invisible surface. Prove that when I roll a roll of tape on a table top, there is another parallel, invisible surface tangent to the bottom of the hole. Also, the hole really rolls on, slips on, and is really supported by said invisible surface. Perhaps something else, but not con art.

Clear, simple, and wrong four ways. There aren't two wheels and two supports. There is one of each for an ordinary wheel. The crux of the paradox is that the inner "wheel" moves farther than its circumference with one full rotation. You mention translation, then abandon it in favor of "slipping." This video (and many others) explain rolling without slipping (or skidding) and translation. What part of “without slipping” do you not understand? Likewise, the smaller "wheel" does not slip nor skid. An inner “wheel” slipping on an imaginary road is as silly as a person slipping on imaginary ice. Translation fully accounts for its moving the horizontal distance 2πR, like it does for its center and the wheel with radius R and the same center. The video makes that clear. This article does not clearly distinguish between slipping and skidding, but it can be done. In essence slipping is rotation without translation, such as a wheel of a car on ice or stuck in snow does and the driver pushes hard on the accelerator pedal. In essence skidding is translation without rotation, such as a wheel of a car does on an icy road and the driver pushes hard on the brake pedal. Both are due to a lack of traction and affect the translation movement of the entire wheel uniformly. An inner "wheel" slipping on an imaginary road is as foolish as a person slipping on imaginary ice. Such foolishness implies translation movement is not uniform – a smaller inner "wheel" "slips" more than a larger inner "wheel." This thread 25 is pages for at least the following: - Whether or not there is a paradox. - Different and conflicting meanings of slip. - The motion of a wheel can be analyzed in more than one way. - Jonathan’s obsession for making personal attacks. The obnoxious, self-deluded ignoranus Jonathan fails to understand a wheel’s motion – especially translation – as describe above. He abuses the concepts slip and skid. That serves his highest aim, which is to bray, sneer, and ridicule. A straight stick/pencil partly submerged in water appears to be bent (link), but the stick/pencil is not bent in reality. It is a classic optical illusion. An inner concentric circle of a wheel may appear to slip, but it does not slip in reality if the wheel doesn’t slip. Jonathan abandons reality in favor of appearance and his scam/ruse. If my not being duped by his scam/ruse counts as stubbornness, I’m fine with that. Suppose John Doe says: “Look at the pencil in the water. It is bent. It is as obvious as hell, but you can’t or refuse to see it. You are visually incompetent and retarded!” And he says this as if light refraction is irrelevant. Analogously, translation is irrelevant in Jonathan’s pretentious “proof.” The following proof is simple and correct. The distance a circle moves translation-wise is always the same distance as its center moves. Since a wheel and any inner circle concentric with it have the same center, the wheel and said circle always move the same distance translation-wise. QED. This is true independent of any rotation, slipping, or skidding.

10. At communist centenary, many Americans still believe in collectivism

"From each according to his ability, to each according to his needs" sounds very appealing to many people. Of course, the slogan suggests this can be achieved without coercion, and it has no regard for normal human economic behavior, which makes it extremely naive. It sort of works in a family, which may account for much of the popular appeal, but utterly fails in a society.
