comment Box counting dimension of the graphs of functions on $\mathbb R \rightarrow \mathbb R$
The box-counting dimension for the graph of a function. Yes, that has been studied. For the function itself? What do you mean by that?

comment Evaluation of improper integral
Good to realize Frullani requires convergence of $f$ at intinity. I assume that's why you moved off the real axis. But now: how to justify interchanging integral and limit?

comment Could someone give a detailed (yet elementary) proof for Jensen's inequality?
First you will need a definition of "convex function".

comment Why is Los Angeles targeted for destruction so often in Hollywood movies?
It 's the easiest place to choose if you're based in Hollywood. We all know Japanese movies tend to destroy Tokyo.

comment What are the most famous examples of theory rebranding?
dynamical systems -> chaos theory ..... geometric measure theory -> fractal geometry (Find a trendy name! Sell more books and attract students!)

comment How can I fund my PhD after the first year?
This depends on your field. In science and engineering, probably funding is available. But good luck getting funding to study medieval architecture ... besides RA and TA there may be AA (administrative assistant). They get some graduate student to do clerical work in the college office, for example.

comment Is it appropriate to use the word “like” in a research paper?
As long as you, like, don't just stick the word in, like, anywhere.

comment How can I obtain an academic reference, if I have been out of college for a very long time?
Agreed. They are more likely interested in hearing from someone who knows what you have been doing recently, rather than from someone who knew you only 25 years ago.

comment Are scientifically detached professors referred to as ‘clinical’?
If any of the answers refers to locations outside the US, let us know. Otherwise, I assume this usage of "clinical" is found only there.

comment Prove that if events $A,B$ independent of C then $P(A\cap B\cap C)= P(A\cap B)P(C)$
You can read David's example... Or you can look up the topic "pairwise independent" in an elementary probability text.

comment Prove that if events $A,B$ independent of C then $P(A\cap B\cap C)= P(A\cap B)P(C)$
If $A$ and $B$ are each independent of $C$, it need not follow that $A \cap B$ is independent of $C$... Right?

comment What does $dx$ mean in a Lebesgue integral?
You would wrote $d\mu$ for integration with respect to measure $\mu$. Carothers does not use $\mu$ for Lebesgue measure. So he does not write Lebesgue integrals using $d\mu$,

comment Is the Windows 10 upgrade event the largest upgrade event?
Does advertising copy constitute a notable claim? I do find that the question on whether Tetris is the best-selling video game ever made is still here.

comment Why did scientists think the orbit of Mars had the shape of a limaçon in the geocentric model?
No, it is impossible to "impose" anything on anonymous dowvoters. Despite multiple requests by newbies. And the proposal to require downvoters to comment has been rejected.

The linear transformation is the "identity". From the space with one norm to the space with the other.
