Under the information-based view of entropy a heat death universe would have high entropy because it would take a large amount of information--a great many bits--to capture it. One would have to say where each bit of material is. Since each bit is more or less randomly located, there is no way to

Russ, I don't get this at all. Two points: 1) There are an infinite number of ways that a line can be parallel to a plane; there is exactly one way it can be perpendicular to the plane. Is that the point? 2) The degree of orientation around the X and the Y axises don't have anything to do with

I agree with the comments on the psychology/perception issue. But I don't agree with this: So no matter which bisecting plane through the sphere we examine, it will always have more sticks parallel to it than to the orthogonal pole. So this actually explains a planar force. There more
