|When the MBTA (Boston's Public Transportation authority) introduces a
new line, the topology of the network become so complex that a train
vanishes...lost in some fourth dimensional properties of the network.
The mathematics in this story is not always accurate. In particular,
I disagree with the statment that a Möbius strip always has one
singularity and a Klein bottle has two. (In fact, the standard
versions of these topological curiosities are non-singular manifolds.)
Maybe the author is confusing the "twisting" required to make these objects
from two-sided 2-dimensional objects with singularity. |
Apparently, this story was made into a movie!

"I read this story when it first came out -- more than a half century ago -- and recalled it in a conversation today, leading me to this web site and an opportunity to vote. Clearly, it was memorable!"
"It has been many years since the one and only time I read "Subway". I can't recall any particular details of the story, except the main plot. That is why I only gave it a "3" on your scale. I do remember that when I read it as a young teen (I'm now in my mid 40s) I thought it was a very good story, and it introduced me to the unusual world of topology. Whenever I see an M.C. Escher print, I am reminded of this story. I'd like to re-read it from an adult point of view, if I could find it again."

I read this story once accidentally (I don't recall how I found it) and was intrigued by it greatly.
Suspend belief and ignore the mathematical flubs and it is an interesting science fiction story, about as good as most in this typically mediocre genre.
Read this story a long ago, but just the fact I still remember it means that it really can leave an impression.. Math is not at all accurate, but the idea is intriguing enough to let you think about it a while, which is what counts.
This is a good story that makes crucial and proper use of math in a way that does not require much expertise from the reader.
I've read this [story] in the 70's, when I was a boy, and I loved it.
Although the story stays vague on how a subway network, even if grown extremely complex, could trigger multidimensional behaviours, the atmosphere you breath while reading the novel is very intriguing and fascinating. It led me to learn some topology, and I was amazed.
I keep re-discovering this story in anthologies every 15 or 20 years. I love it! My very first exposure to it, though, was actually as a story in one of the Marvel Comic anthologies in the 60's. I was delighted the first time I discovered the original story.
The math may not be accurate, but the story couldn't exist without the math in question, so I gave it a 4 on that. 5 for literary quality-- I read it in an old anthology I found at a yard sale and loved it.
Read this as a kid and loved it at the time. Opens a child's mind to many possibilities. Would like to read it again and see how I relate to it these many years later.
I read this soon after it was published in the 50's, and I've just got back from the 4th dimension.
I probably still have the original magazine in the attic. Since I am arithmetically challenged I have no right to judge its accuracy, but it certainly was memorable--for more than fifty years. And it can be found in various anthologies. As for that lofty smart aleck who finds the s-f field mediocre, he should really get to know it better--Asimov, Clarke, le Guin, Ellison, Sturgeon, Russ, Delaney, Dick, Heinlein, etc etc etc? Come on, wise guy!

My Father owned some collections of science fiction, published in the 1950's, and I devoured them when I was a child in the 1960's. Being from Dorchester (a neighborhood of Boston mentioned prominently in the story), and also a frequent rider of the MBTA, I was particularly intrigued by this. I have re-read it perhaps 10 or 12 times since the initial reading. I am not well-versed enough in mathematics to pass serious judgement on that aspect of the tale, but it DID introduce me to topology and I've found what little study I've made of it fascinating, so I've always been thankful to the author for that!
Very much my favourite sci-fi short story ever.
I did a science fair project on Mobius strips back in 1957. More recently, I began wondering about multi-sided Mobius strips. The only conjecture (no proof) I have is that the first partial turn always reduces n sides to one. I got up to ten sides and saw some patterns begin to appear with each partial turn, but I haven't carried it any further. I would surmise that the problem has been investigated by minds more skilled in these matters than mine!
Read it the second time as a kid in Clifton Fadiman's Fantasia Mathematica in the late fifties. I was influenced....earned PhD in mathematics, Geometric Topology in the early seventies.
In the late fifties, as an MIT student, when
passing through many of the stations mentioned, I was often reminded
of A. J. Deutsch's wonderful A Subway Named Moebius. Since the
date of this fantasy was 1950, the thought has occurred to me that
Deutsch might have been inspired by the "MTA Song", created for the
1949 Boston mayoral campaign of Walter O'Brien, who ran as a
Progressive Party candidate. Walter didn't do well, but the song did -
with a few minor changes to the words ("Charlie"
instead of "Walter"), it became popular, and was
recorded by the Kingston Trio later in the fifties. As in
Moebius it involved someone trapped on the subway - by
economics (lack of a nickel), not by mathematics!
