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 non-negative 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 re-open 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.

But I personally would avoid a financial advisor who has repeatedly gone through bankruptcy. I am not convinced that the wisdom of the state is invariable.

To draw an analogy: if your experience of someone is that they make up stories all the time, you are not likely to treat any new story they tell you as fact. I honestly interpreted the sentence as implying that the definition of each real number is unique, perhaps influenced by all Zylo's previous output. If that wasn't the meaning that he meant to communicate, I was in error. But I think it's an entirely reasonable interpretation in the light of the other stuff he writes.
I mostly agree with this. I was thinking about the lying person analogy, and extended to something more extreme, say a criminal with a long history of crime. Naturally it isn’t a good idea to reasses the behaviour of such a person each time they break the law and possibly endanger society. Indeed their history and reputation does matter. The problems they cause may have a recurring theme (namely, law breaking).

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.

If the ‘block’ feature was better I think we would all be happy.

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 agree here too, or at least up to focusing about other questions in the thread. I think we've got all of our "zylo bashing" in for one thread.

Limit 1) Calculus. $\displaystyle \varepsilon, \delta$ $\displaystyle \lim_{\lim_{n\rightarrow \infty}}$ .499999 = 1/2. property 2) Limit of n-place 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.

You know a state that has (any) wisdom?
