What should be learned in an introductory analytic number theory course?
I'm curious: what is "Pollack's new book"? |

Gently falling functions
Sorry if that's a silly question but in example 1), a particle starting at (0,1) won't go anywhere unless you give it some initial horizontal velocity. Are you suggesting that the separation point tends to the indicated point as that velocity tends to 0? |

Proof that any NP problem can be reduced (in P time) to any problem in NPC?
I don't understand your modified question. Of course every problem in NP can be reduced some subset of NP problems - it can be "reduced" to itself, and often to lots of other problems polynomially-equivalent to it. Why does that imply that NPC is empty? |

Is there any sequence $a_n$ of nonnegative numbers for which $\sum_{n \geq 1}a_n^2 <\infty$ and $\sum_{n \geq 1}\left(\sum_{k \geq 1}\frac{a_{kn}}{k}\right)^2=\infty$?
In line 3, did you mean "the sequence whose $n$-th term is..."? |

Proof of no rational point on Selmer's Curve 3x^3+4y^3+5z^3=0
@Ho Chung Siu, do you happen to have a copy of that paper anywhere accessible? |

What is the high-concept explanation on why real numbers are useful in number theory?
This is totally tangential but I just want to say I strongly disagree with the sentiment of the first sentence. If statements and proofs were typically "in the same world", math would be so dull. Dystopia. |

Motivation behind Tutte's 1-factor theorem
I changed the question's title to better correspond to its content. You don't appear to be interested in the historical development of the theorem, but rather the motivation behind this characterization. Perhaps a better way to phrase the question would be to ask, is there any algorithmic or theoretical advantage to this (rather daunting) condition. |

Is “second-countable implies separable” equivalent to the Axiom of countable Choice?
Surely this requires only the axiom of countable choice? |

How many finite simple groups of order $p+1$?
n!/2-1 is prime for n=5, 6, 9, 31, 41, 373 ... (sequence A082671 on the OEIS). Is it known if this sequence is finite? |
