Mine did not provide the units, but ni sutra is a speed/velocity and not an acceleraion or other measurement. >>le parbi be leni leni sutra cu cenba ku le temci >--More-- > >[You're missing {bei} there.] > >Why {le temci} and not {le ni temci}? Off the cuff decision without a lot of thought. I'm not sure whether an interval is a quantity or not. Probably not given your questioning of it. Remember that I do not habitually look things up, but try to maintain my Lojban usage (such as it is) on long-ago memorized gismu lists. When I do look things up, it is a brief check and not a careful analysis of the place strutures. >Is {le ni cenba} different from {le te cenba}? Probably not. See my immediately preceding comment. >And you didn't explain what was {le se cenba} there. well, amounts are numbers, so they change in value. leka namcu, perhaps. >Before tackling acceleration we should know how to deal with >velocity, and before that with displacement. For displacement >we can use ve muvdu: > > le ve muvdu cu mitre li bi > The path is 8 in meters. OK > le ve muvdu cu klani li bi le ka mitre > The path is quantified as 8 in meters. A path is not a quantity. It can be measured in some property to be a quantity but it is not itself a quantity. >Or even: > > le muvdu cu klani li bi le ka le ve muvdu cu mitre > The mover is quantified as 8 in the meters of its path. Likewise moving things are not quantities. You have an odd (to me) sense of what a quantity is. (Now I admit that if you were to redefine klani, as I challeneged you to do, then you could make the x1 of klani into a thing that is measureable, but then you have to change the wording.) > le ni la djan cu jmive cu klani li pamu le si'o nanca > The amount of John's living is 15 in a scale of years. > >But I don't understand why {si'o} is any better than {ka}. >Is {si'o} really usable for dyadic relationships? Probably it is more conventional than mandatory. The scale is characterized as an idea and not in terms of the properties of its units. I am also ever wary of using ka around you since you seem to want to put a ce'u in there all the time or a xokau or some other stuff that I cannot often understand. >>??? le gugde cu klani li ciciki'oki'o leka le turni cu kancu le .y. .y. >>ni le prenu cu xabju vo'a > > le ka le turni cu kancu lei xabju be ce'uxipa ce'uxire > >>or maybe le cmima be le'i xabju be co'a > >I don't think you can replace {ce'u} with {vo'a} I don't use ce'u unless it is clear that I must.

But the wording of the place structure of mitre etc. specifically indicates thatthe x1 is being measured. Thius is not the wording of klani. You who argued djuno largely on the strength of a particular interpretation of what my wording had to mean are introducing a meaning not suggested by the word "quantity". >I am not very happy though with the lujvo that I used above for "x1 is x2 in >meters per second", mainly because it's not easily generalized to >get "x1 is x2 in meters per second squared" for example. Anyone >has any ideas how to make such lujvo? It was my intent in ages past to make the lujvo for all units that are based on the standard metric units based on a lujvo for the concept being measured followed by gradu. This by convention. It probably cannot be made to fit the lujvo-making place structure rules. For non standard units, I would probably then prepend the altered component units. jmagutci--gradu -> ft/sec**2 Athelstan and I tackled lots of problems of this sort in concocting the gismu list. We had to have a workable proposal for a lujvo for almost any concept that we could think of, and I have a couple of hundred pages in my file of ideas that we actuakly wrote down (and we wrote down but a small fraction of the ones we contemplated). But all this was when lujvo-making was intended to be far more adhoc than people turned out to prefer, so many of the ideas will not work under the Ch 12 rules. Someday maybe I or someone else can go through them. (But not till we get people to analyze the ones actually apearing in Lojban text online - alist that probably grows by hundreds or thousands per year). lojbab
