I know there are already meta-posts about this, but in your opinion, what makes a [book-recommendation] question opinion-based or not opinion-based? It seems to me that some [book-recommendation] questions are closed as opinion-based while others receive lots of upvotes on the question and answers and not a single close vote and I don't really know what distinguishes these quetions

lacking focus

@LukasHeger probably something like "recommend me the best book on the topic" would be opinion-based, while questions of the type "what's a good book to study X from" or "what's a good book to find X in" are not

so, I think, a good book-recommendation question should consist of a lot of background behind the question

you can't avoid basing things on your or others opinions, that's simply not possible

I'd like the one posing such question to explain what the contents they would like to learn (while not always possible), and maybe even more stress I would put on the answers to explain the contexts of the material

I think answers in this case are more important because this is something everyone can throw in a "this book is good" and that doesn't have much substance to it

so to reflect that, ideally, the question should be really good too... perhaps written by someone who actually studied the topic and is asking it just to create a question that would serve as a reference for others

but such things don't happen...

This seems to be a question based on a poorly worded question, and is not likely to be of lasting use or importance. I am tempted to close it as a duplicate of any of a million "Find the $n$-th roots of $-1$," but I'm not sure that it is worth keeping at all. :/

Sine of the Time

@Xander I've seen this question at least 3 times between today and yesterday; I've linked one in the comment but the other one was probably deleted (I'm pretty sure it was deleted but I've voted to close so maybe you can find it). Is this normal?

@SineoftheTime Seems like something that, in general, should be flagged.

Though in this case, I've looked into it---no need for flags, now.

I'll keep that in mind for the next time. Thank you

You start out with any natural number. Let's choose 50 for this particular example. You divide the number by it's smallest smallest prime factor. So 50 divided by 2 equals 25. Then you multiply it by 3 and add 1. 25 multiplied by 3 plus 1 equals 76. Now you keep on alternating between these 2 rul...

Q: Sets of Powers of 2 and Collatz Conjecture

Any positive integers can be represented as Sum of powers of $2$ or $2^n$. And all numbers lie between powers of 2. All positive integers also can be represented as $3n$, $3n \pm 1$. Applying rule in collatz conjecture is so simple but difficult to think how every number gets back to 1. Let us th...
