I just read his first post; his entire premise sounds faulty. How can both distance and speed be infinite? makes no sense to me.
No... it's all limited to the workout (situp, pushup, running, swimming). However I am still working on the elusive pullup.. I am just a few days away from getting one pullup Please Register or Log in to view the hidden image! For that, I am using a weight machine to work my lats.. and I am doing a few dips to help (I think they do). Oh... I read the original again and I missed it Please Register or Log in to view the hidden image! I never liked geometry. It's odd, but I don't.
No I think it's more than spelling. That second reference gives 5 different defintions of "infinty", so the opposite is 1) finite 2) bounded 3) definitely large or indefintely small 4) a function I can't bothered to work out Please Register or Log in to view the hidden image! 5a ) screwed up focus the camera/ telescope 5b ) a focus on the camera where nothing is in focus
I see what he means when he talks about that... but just as you did, I sensed a faulty premise. I think for most of the thread I was mostly working to figure out what that faulty premise was... since I wasn't even sure.. so I just keep picking at his points and see what he thinks about that.. then I pick some more.
I think that might be why I am having trouble with the word "finity." Well if it cannot be defined, then there is no point in doing such Please Register or Log in to view the hidden image! Lol.. what?
Well if speed is distance over time then time would be infinite too and thats equal to what? standing still? Weird.
Well if I remember correctly... he is making the argument that infinity/infinity = 0... but he fails to see that it really doesn't make sense.
That's exactly what I was going to say. But I can see his reasoning, sort of. If the distance is anything LESS than infinity and the speed is infinite then the time will be zero. 5/infinity = zero. 6/infinity = 0. etc. But infinity/ infinity, as you said in the third or fourth post is undefined and indefinable. Like operating with singularities. It just falls apart...
You are looking at the limit of n/x where n is a number and x gets bigger and bigger (limits in calculus). The limit of any of those is zero. However, what about this? (2x)/x? It looks like infinity/infinity which would SEEM to be zero... however as you can see, (2x)/x = 2... the limit is 2. My point is not limits or calculus.. but that you have to know what you are working with before you make a claim.
If he's talking (originally at least) about distance and speed then that narrows it down, no? So we're back to t=s/v. If s is infinite then regardless of v, t = is infinite. If v is infinite then t = zero. is s=v then t=1 etc. for all "values" of s, if s=v. I think that's what he's implying. But I could be wrong, and like you say when s=v=infinity then it doesn't work that way.
Well if that was the case, the thread would have ended pretty quick. Or maybe the thread would not have even have been.
