I am very sad, I saw recently an interesting question, and I posted an answer. After it first disappeared, I posted it one more time. It took me more than one hour, to write a complete answer. And now, after a few hours, nothing, I don't see my answer.
This is very deceptive, and didn't encouraged me from invest time and energy to contribute to MY.
Have you an explanation please?
Your answer was deleted. It's still visible to you (and mods and users with >10k reputation) if you go to the question on the site. (If you view the question in the mobile app you won't be able to see it, nor would anyone else, since the mobile app doesn't display deleted posts. In that case it might seem like it just "disappeared".)
As for why it was deleted: the question asked there was "In what way can the irrational and infinite number Pi be derived from the written Torah?"
As far as I can tell your answers were jokes. Joke answers are not allowed on serious questions, and not allowed at all outside of the beginning of Adar (see the Purim Torah Policy). (I see why you may have been confused about this because the other answer to that question is also somewhat of a joke. Arguably it should be deleted too.) EDIT: you seem to indicate it was not intended as a joke. I personally still don't understand how that is possible but perhaps that could be sufficient to alleviate this concern.
In addition, you don't cite "the written Torah" at all anywhere in your post so it doesn't answer the question the OP posted. Answers on Mi Yodeya need to actually answer the question, not just be related or somewhat similar.
I note that if a post is deleted, the solution is NEVER to try posting it again as if we won't notice that you have circumvented the rules. You can edit it to try and make it better applicable to the question it is on, flag it for moderator attention for undeletion, or bring it up to discuss here on Meta or in chat. Don't start a war with the community by posting things against their explicit wishes. (Someone doing too much of that may have to be suspended.)
If a mistake was made (or the community feels like it should be so) we can always undelete a post.
It looks like you originally posted:
In some high math courses, π is defined as the number such that e^(2π•i) = 1.
But, what is exponential? The application that transforms addition into multiplication (if f : x --> e^x, f(a+b) = f(a)•f(b)).
A classical source (Talmud or Midrash) deduces from a verse of Isaiah that, leatid lavo, tsadiqim will make a great dance in the shape of a circle "around" H-m; while "showing Him" with their hand. And I once heard that, all the tsadiqim, everyone with his own personality and point of view, will understand that everyone was necessary in the Great Plan of the Universe.
So, this can say that, to approach the Unity, we need the whole circumference, in a situation where we can add our particularities to make a product. And all this along the imaginary line, because of the צלם notion.
After this was deleted, it looks like this was your second answer:
2π is generally known as the ratio of circle circumference over its radius. In some high math courses, π is more rigorously defined as the (smallest, positive real) number such that exp(2π•i) = 1. Where exp is the (complex) exponential, and i the basis of the imaginary line. Equation above even get more sense by defining exponential as power series etc.
Okay, but, now, what represents the exponential? An application that transforms additions into multiplications:
exp(a + b) = exp(a) × exp(b)
Now, the Talmud Taanis 31a says
אמר עולא ביראה אמר רבי אלעזר, עתיד הקב''ה לעשות מחול לצדיקים והוא יושב ביניהם בגן עדן וכל אחד ואחד מראה באצבעו שנאמר (ישעיה כה) ואמר כו' זה ה' קיוינו לו Oula Biraa said from Rabi Elazar: Hqb"h will make a circular danse for the righteous, and He sits between them in the Gan Eden, and every one shows ...
Once I heard an explanation as a metaphor. In this world, every one has his own neshama, personality, point of view to Hqb"h. But in the future, tsadiqim will make a circular danse, and every one will range the whole circle, every one will alternatively take all the places, and understand all the points of view. And, as a result, they will 'show' the 'center', they will apprehend and praise Hqb"h.
Okay, so we have an abstract metaphor that, when we could sum up the whole circle, and take a product, we will apprehend the Unity. And this is learned from the verse in Isaiah 25, 9. Reminds you something? Returning in mathematical notation. What sums up yielding a product? Exponential. Along the imaginary line, because it will transcend limits of this current World. And when you apply this to the Circle , you reach the Unity.
exp(i•x) = 1, so x = 2π
(And because the radius is not mentioned, seems to be taken as the simplest one: 1)
So, circumference of the unit circle is 2π. End of proof.
I wasn’t the one who deleted either one of these answers, so I can’t know for certain what the precise issue was. However, looking at these myself after the fact, I can see some problems with these that may have led to their deletion:
I hope this helps. On behalf of the community, I’m sorry you had this experience, and I hope you decide to stay and share more of your insights here. One of the reasons that I included your posts here, besides to show you some potential problems with them, is so that you don’t have to start entirely from scratch - you can take these and modify them to try to address these concerns, rather than starting from a clean slate, if you’d like.
