Why was the alien threat in The Next Generation episode "Conspiracy" never followed up? In the Star Trek The Next Generation episode  Picard and crew are drawn into an alien conspiracy to take over the Federation. This ends with Picard and Riker destroying an alien "mother" beast, but not before it manages to send a signal to an uncharted sector of space. The feeling at the end of the episode is that this will be a threat that the intrepid crew of the Enterprise would be facing again at some point, but this never happens.   Why was the implied threat at the end of this episode never brought up again on the show? A shrinking map that is not a contraction no fixed point. Working from Munkres.  Show that $f: \mathbb{R}\to \mathbb{R}$ given by $f(x) = [x+\sqrt{(x^2+1)}]/2$ is a shrinking map that is not a contraction that has no fixed point.   I figured out the fixed point part but have no clue how to show the other part.  For the fixed point part $$f(x) = x \Leftrightarrow x = [x+\sqrt{(x^2+1)}]/2$$  then $$2x = x + \sqrt{(x^2+1)}$$ $$x = \sqrt{(x^2+1)}$$ $$ x^2 = x^2+1$$  Which is a contradiction.   Thanks in advance. How to properly unwrap my mesh? Is there a way to automatically unwrap my character? If not, is there a tutorial or something? The browser's "Back" button cause problems with the review buttons I am looking for the definition of when I am allowed to do forward declaration of a class in another class's header file:  Am I allowed to do it for a base class, for a class held as a member, for a class passed to member function by reference, etc. ? How do I give text or an image a transparent background using CSS? The prepositions “with”, “at” and “for” are also used to associate a business title with a company's name. It seems that they are interchangeable, with no (significant) difference in meaning. The following examples taken from The New York Times website seem to confirm that:      Until now, said Justin Nielson, a senior analyst for the media   research firm SNL Kagan, “there really hasn't been any direct   competitor . . .      “The consumer is still deleveraging,” said Jason Goldberg, a senior   analyst with Barclays. “It's not a lack of supply; it's a lack of   demand.”      “There’s the party of fear and the party of despair,” Nikos Xydakis, a   political analyst and an editor at Kathimerini daily, said.   Are they really the same as for meaning? If it isn't so, what is the difference between them? Another "can't use Alt. Series Conv. test" (How do I determine if it converges or diverges?)

Multiple solutions for a particle in an infinite potential well I am starting to learn about quantum mechanics and was wondering about the solutions to a question about a particle in an infinite potential well of length $L$.  The solutions are: $$\psi_n(x) = \sqrt{\frac{2}{L}}\sin\left(\frac{\pi n x}{L} \right)$$  And I was wondering what is the meaning of $n$. Isn't there supposed to be only one wave function? In that case, $\Psi = \sum_{n=1} ^\infty a_n \psi_n$, but what are the $a_n$? Or maybe it is probabilistic, and we don't know which $\psi_n$ the particle is currently in? Limit question on independent random variables (Exercise 4.2.4 from Grimmett and Stirzaker) Let $\{X_r | r \geq 1\}$ be independent and identically distributed with distribution function $F$ satisfying $F(y) &lt; 1$ for all $y$, and let $Y(y) = \min \{k | X_k &gt; y\}$. Show that $$ \lim_{y\rightarrow \infty} P(Y(y) \leq E[Y(y)]) = 1 - e^{-1}. $$  I managed to show that $E[Y(y)] = \alpha(y) = (1 - F(y))^{-1}$ and that $$ \lim_{y\rightarrow \infty} P(Y(y) \leq E[Y(y)]) = \lim_{y \rightarrow \infty} \left( \sum_{i = 1}^{\lfloor \alpha(y) \rfloor} {\lfloor \alpha(y) \rfloor \choose i} (-1)^{i+1} \alpha(y)^{-i} \right). $$ And the expression on the right, according to Mathematica, does indeed seem to converge to $1 - e^{-1}$. But how can I show that this is true? Can anyone give me a hint? Prove that if $a$ and $b$ are odd, coprime numbers, then $\gcd(2^a +1, 2^b +1) = 3$ Prove that if $a$ and $b$ are odd, coprime numbers, then $\gcd(2^a +1, 2^b +1) = 3$.   I was thinking among the lines of:  Since $a$ and $b$ are coprime numbers, $\gcd(a,b)=1$. Then there exist integers $x$ and $y$ such that, $ax+by=1$.   Then, $a=(1-by)/x$, $b=(1-ax)/y$  So if I write $2^a+1$ as:  $2^{(1-by)/x}+1$  Then can I say that the above expression is equivalent to 0 (mod 3)?

Count down in timeout is cut off The time out countdown which is flying in is missing half of the number.  Note the 33 here:        Can this be fixed please? Ubuntu 16.04 software center doesn't have many apps By viewing the polynomials as a difference of two squares, factorise the following polynomial: $$x^4+x^2+1.$$ I searched but couldn't find a way to solve this  Edit: By using Hans Lundmark hint, I get:  $$(x^2+1)^2-x^2$$   Is it fully factorized?
