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? [...] >A remote axis expression cannot, therefore, go in the >normal tense place, since it will there attach to the x1 sumti (and putting >{cu} before it is illegal). 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. >This >meets the present problem; the others (like "How do you give precise >tensors, >e.g., 'fifty minutes ago and five miles away'?") will have to wait. Are you thinking of the termset thing here, or do you have some other card up your sleeve? mu'o mi'e xorxes _________________________________________________________________ Join the world’s largest e-mail service with MSN Hotmail. http://www.hotmail.com
