@Maschke I do not think that I suffer from ZDS. I am trying to figure out what zylo's vocabulary means. Apparently, he IMPLICITLY considers zero to be a natural number, which is not a universally accepted definition, but is certainly a definition acceptable to me and many others. I think he means a sequence of nonnegative integers less than 10, but that is not clear and may not be a stipulation necessary to his argument. And I as yet do not see how an infinite sequence of digits representing 100 differs from an infinite sequence of digits representing 1000: in each case, the sequence presumably starts with 1 and is followed by an infinite number of zeroes. If I am wrong in that presumption, Zylo needs to explain how those two real numbers are distinguished. Finally, I doubt it is feasible for humans to forget history and past interactions completely. The decision to close the topic was understandable. The decision to reopen it was likewise understandable. And the warning to try to keep things civil was also understandable. But to ask people to ignore repeated experience is not feasible. I strongly suspect that Archie and others are correct that we are about to get a rehash of arguments made numerous times before.

In England every financial advisor has to provide a government warning to the effect "Past results are not a guide to future performance"

But then I was thinking, these are questions pertaining to mathematics. Questions that have clear and rigorous answers. And certainly these are answers that have been given by many of you here, over and over. And they can keep on being given, like a broken record. Heck, even write some tricky software to respond instead.. However I fail to see why, in discussions of mathematics, any thought should be given to history or reputation. A lot of mathematicians take the viewpoint that they are discovering rather than inventing. An archeologist may become well known for successfully discovering and documenting multiple artifacts, but what’s really more important here, the archeologist or the artefact? What does the succcessfulnes of the archeologist have to do with it? This would all be much easier if we weren’t .. human.

The problem is that blocking a user here doesn’t make things dissapear completely, and you end up getting curious about what’s being said anyway.. If the feature removed all threads started by the user for you only, that would be better.

I wonder if Zylo is sitting back watching all this and having a real good laugh. The chaos ensues. Alright I’m done. Goodnight.

I meant to elaborate on "Limit". Limit 1) Calculus. $\displaystyle \varepsilon, \delta$ $\displaystyle \lim_{\lim_{n\rightarrow \infty}}$ .499999 = 1/2. property 2) Limit of nplace decimal as n $\displaystyle \rightarrow \infty$ $\displaystyle \lim_{\lim_{n\rightarrow \infty}}$ .499999 = .4999999..... $\displaystyle \rightarrow$, definition Last edited by skipjack; February 23rd, 2018 at 10:10 AM.

Would that point still apply if each "9" were replaced by "0" and the "4" were replaced by 5?
