comment Continuous extension of Riemann maps and the Caratheodory-Torhorst Theorem
the map you wrote is unique up to pre-composition (not post-composition) with a fractional linear map.

comment Stability of real polynomials with positive coefficients
@Colin Tan: we knew about Catlin and d'Angelo results, and even discussed "our" theorem A with each of them. We could not derive Theorem A from their statements. I mean the relation of the condition about "first two and last two" with their conditions.

comment Useless math that became useful
@YangMills: if you mean the story of Archimedes burning the ships, this is a later legend. Both theory and experiments show that this is impossible.

comment What are reasons to believe that e is not a period?
@XL_at_China: You are raising complicated issues which would require long discussion, possibly out of scope of this forum.

comment What are reasons to believe that e is not a period?
@XL_at_china: I am not sure what a "strict way" means. It is not a theorem. It is a statement about real world:-)

comment Motivating mathematics(particularly algebraic number theory) through historical problems
On my point of view history of mathematics is a part of mathematics, and it does not have to be separated. Same applies to the questions about math literature (of graduate+ level). What is wrong with placing such questions here ?

I disagree with those who closed the question. I second for the Edwards book. Books like this are rare and useful, and certainly relevant to those doing "research mathematics".

comment Convergence of an integral containing the Fourier transform of compact supported function
$\hat{u}(0)=\| u\|_1\neq 0$, so the denominator is never zero, so what is the question?
