Oh, for a second I thought $r$ was rational. Deleted.

@RaceBannon Really? How so?

Take logarithms. You want to analyze $f(t)=t^{-1}\log t$ and its repeated values.

comment Why formulate continuity in terms of pre-images instead of image?
@CameronWilliams They are equivalent, of course. It would be ridiculous if they weren't! I am just showing that you can formulate the definition of continuity of a function in terms of images of sets.

comment How do I generalize the derivatives / integrals from multivariable calc?
Dear Henry: the effort you put into this post is very valuable, but since the answer you were looking for is apparently obtained by reading a book on the topic, I have locked it in an effort to avoid further lengthy answers or posts. I encourage you not to edit this further (nor the post or the answers). This site is not meant to be used as a blog.

You moved three matches?

comment What's the last whole number before a googolplex?
I assume it is an age impediment. If the kid was older, you could just say: "Well, son, it is just a c**pload of nines."

(Note that this was already posted and closed by the community, too. If your question was already closed, the correct course of action is to edit said question and wait for a reopening, not to post a duplicate.)

comment A proposed method for further abstracting prime numbers
@RandallS I meant to comment on the paper works. Regarding the post, yes, it is off-topic, unfortunately. The main problem with the post is that you don't ask anything. The site is not meant to be used as a blogpost site, we rather welcome precise questions than long posts that wander about. The second problem is that the content of it is quite unclear, and phrases like "A zero-point line, aberrations, coherence, convergence, divergence, something from nothing, I cover all that in my paper." do not help your case.
