By the way, does anyone know why so many science fiction writers
descripe spinning space habitats as being longer than they are wide?
Such habitats are intrinsically unstable.  But habitats that are wider
than they are long are intrinsically stable

I know that the habitats are supposed to have stability controls --
just pump water around.  Nonetheless, it is easier to keep an
instrinsically stable system stable than to stabilize an unstable
configuration.
