@robjohn If I have a list of ~7 questions that could be merged (i.e. questions are exact duplicates, yet each may have several answers), what is the best way for me to propose that merge? (They're currently closed as duplicates of each other.)

@anorton Often merging is harmful because answers to one question may not apply to another.

@JasperLoy That is often the case. Consider, however the following:

an ideal is a subset which is closed under addition, subtraction, and "ambient multiplication" (that is, multiplying an element of an ideal by any element of a ring yields another element of the ideal). for instance, the even numbers, or the integer multiples of an integer n for any n, form ideals.

@TedShifrin it's a computational problem that encapsulates most other problems (for instance, discrete logs and graph isomorphism problems are really just special cases). suppose there is a group, and a (say complex-valued) function out of it which is constant on cosets of an unknown subgroup H (but takes different values on different cosets). we can query the function's value at different elements of the group, and using this ability need to figure out the subgroup H (or really a generating set).

My complaint is that the complete-answerers are insensitive to those of us on the other side. I don't think it's symmetric. I have been known to write complete answers to very sophisticated questions.
There's also the issue, as I mentioned to you re JDH, that many of us still are old-fashioned and assign homework for a significant portion of the grade (in my math major classes, it's typically 35 or 40%).

However, since you love physics, let me refer you to three questions in particular to ponder: #10 in the first section, and #8 and #10 on p. 112-113. @beginner
@Bill: I was very disappointed that we couldn't get a hints only tag. Even more disappointed how the complete-answerers run roughshod over the OPs who say "Just a hint please. This is homework" and still give complete solutions. Makes me livid.

#10 is the square wheels?

It's hard to tell you young'uns to be patient, @beginner. But maybe something in my diff geo will spark interest in you so that you want to learn background for it. :)

@BillDubuque relegating complete, detailed solutions to problems that are not amenable to hints or constructive back-and-forths or else where no one has proven initially willing to provide hints or engage in back-and-forths, or else where the problem is fundamental so a complete exposition would be nice to have somewhere on the internet, etc. anything which doesn't interfere with the other teaching style, in other words. I don't often see you around the threads where toes are stepped on, I think.

@beginner (and others): I have another famous one for you. I stole it from a MAA (Math Assn of America) book, but it comes from a Sherlock Holmes mystery ("The Adventure of the Priory School").
Sherlock looked at bicycle tracks in the mud and discerned which way the bicycle was headed, and thereby solved the murder mystery.
Let me find my picture that goes with it.

Why does mass alter gravity? I mean I guess it is just 'because' it is so, but that doesn't feel like a good reason
Like temperature being movement of atoms is fine because of friction at a small scale(that may not be right) and that feels like an alright reason, but mass being the causation of gravity doesn't feel good
