I remember I was very confused by these expresions when I first
started learning Lojban. To me, "axis" suggests a straight line,
not a point, so I prefer "origin" for the point where the vector
originates. Also, the length of a vector is usally called "norm".
Tensors are a generalization of vectors, (as force is a vector,
tension is a tensor). The first time I read that Lojban tense
used "tensors" I was really curious, until I realized they were
nothing but the length of the vectors. Is this use of "axis"
and "tensor" standard in Logic, or is it a Lojban thing?

I think you may be mislead by the parser here. The remote axis
expression cannot be attached to the x1 sumti just by juxtaposition.
You need {ne} or one of its kin to attach it.

Are you thinking of the termset thing here, or do you have some
other card up your sleeve?
