So I shall employ it to make a point. Come hither, Plato, and let me ask a question of you. Do you think that AMD (Angular Magnification Distortion) is another name for “rolling ball” as it has been affectionately called as of late, and that the two terms, therefore, mean the same thing?Certainly they do, Socrates. Would you also say, Plato, that a virus and catching a cold are the same thing? No, sir, I would not, one is the cause and the other is the effect. Verily, I say unto you that this relationship is also true with AMD and "rolling ball." The AMD is the cause, and the RB, the effect. However, not everyone who has been exposed to a virus catches a cold. In a similar manner, not everyone who is exposed to AMD experiences "rolling ball."You have much wisdom in these matters, Socrates, and can see what most others cannot.You speak the truth, Plato, which makes me to wonder why the busts they carve in my likeness never have eyes. :smoke:* excepted from the "Rolling Ball Dialogues" by Plato.
