Arthur C. Clarke's "The Wall of Darkness" - what's the point?
On Mar 16, 12:14*pm, wrote:
I just got done reading this story and was a bit perplexed at the end too.. I think, as a user posted above me, that this is more of a mood piece focusing on the philosophy of our existence and our search into "the great unknown." I took it as more Shervane representing our general quest for knowledge. His teacher stating that what is seen on the otherside will drive one mad refers moreso to the frustration that ensues when the answers we find are more confusing, unexplainable, and sometimes less climactic than the questions and ideas we initially set out for and hoped to find. By traveling to the other side of the Wall of Darkness, Shervane hoped to be awakened and enlightened beyond his human ignorance. Through his quest, he was seeking order, meaning, and patterns in our, essentially, existential chaos. As he finds out, like most humans do, there are no patterns we can see with our narrowminded thinking and no clear cut answers as to why we are here, and what happens when we cease to exist. Essentially,it is a journey we will all take alone throughout our lives as Shervane did in the story. ================================================= Thanks for bringing this thread up again which I hadn't seen when it first appeared. I didn't know Clarke had written such a story with such a highly abstract mathematical topic at its focus. As the others mentioned, I think Clarke just wanted to write a story based on the topological concept of a "one-sided" surface. Bob Clark |

I thought I was familiar with all of ACC's science fiction, but I must have overlooked this one. I've just read it - a most interesting storyline.

what is the difference between a M-strip and a K-bottle?

"In mathematics, the Klein bottle (pron.: /ˈklaɪn/) is an example of a non-orientable surface; informally, it is a surface (a two-dimensional manifold) in which notions of left and right cannot be consistently defined. Other related non-orientable objects include the Möbius strip and the real projective plane. Whereas a Möbius strip is a surface with boundary, a Klein bottle has no boundary (for comparison, a sphere is an orientable surface with no boundary)." http://en.wikipedia.org/wiki/Klein_bottle See also: Möbius strip. http://en.wikipedia.org/wiki/M%C3%B6bius_strip Another distinction is that the Möbius strip can be fully realized in 3-dimensional space while the Klein bottle can not. The image usually shown for the Klein bottle is just the projection of it into 3- dimensional space. It's like how the common picture of the tesseract is just the projection of this 4-dimensional cube into 3-dimensional space: http://en.wikipedia.org/wiki/Tesseract Bob Clark |

as Bill pointed it out, a Kbottle can be cut into two Mstrips,
but they are really the same thing, if the ideal of "compactness" is modified. that is, there is a standard way to parameterize the Mstrip, which arbitrarily limits it to being a strip, half a unit wide on both sides of the generating circle. if it is an infinite surface, it has an irreducible self-intersection, same as the Kbottle, although this is usually handwaved-away with some stuff about "4dness." anyway, you can "do" an Matrip with an old bike tube, in more than one way. or, maybe it's the Kbottle manifestation. |
