comment Number of possible non crossing paths on a grid of $m$ by $n$ size?
@suncup224 : Maybe, not sure why I really pondered about this, I should be applying for jobs rather than pondering math questions.

@Aleksandar : tried to align it to make it look better, not sure if this is prettier.

comment Are these inequalities useless for getting better estimates? If not what is needed?
I had seen the original idea for the proof of divergence (the first 2 inequalities), I have no original thought here just like a juxtaposition monkey randomly trying different different things to see if can sandwich the harmonic series between two other estimateable series and then squeeze them. By no means I am trying to find a better estimate than $\ln n$ for estimation of harmonic series

comment Is it possible that some combination of partial sums of $\sum \sqrt{k}$ be a rational number? $\text{where } k \text { not a perfect square}$
@barto : thanks, does math.stackexchange.com/a/437374/43288 answer it for the case of square roots only?

revised Different methods to compute $\sum\limits_{k=1}^\infty \frac{1}{k^2}$
k is the usual index for summation, n is used for the upper limit of summation.

comment What is intresting about $\sqrt{\log_x{\exp{\sqrt{\log_x{\exp{\sqrt{\log_x{\exp{\cdots}}}}}}}}}=\log_x{e}$?
The answers are the to the content, your title and content are different. Title is asking what , content is asking why? I started a more specific question regarding what is interesting math.stackexchange.com/questions/1392673/…
