"the police conspiracy" vs. "the police's conspiracy" I am making a skydome and I have a texture hooked up with an emission shader for it, however, since the dome is blue it only emits blue light. Is there a way that I can have the whole sky illuminated and have the light reaching the rest of my scene be a different colour? Asking the position of a person in a sequence How to ask the position(?) of a president (like 10th) of a country, correctly? $ KC $ spaces imply $ US $ spaces , but vise versa is false. How to pronounce "Moderators's"? If I want to use the plural of &quot;moderator&quot; and also add the apostrophe plus S, how do I pronounce it? How do native speakers pronounce it?  Moderators = moderatorz Moderators's = moderatorziz or just moderatorz?  A sentence is:  &quot;I always thought that moderators's decisions seemed fairly arbitrary.&quot;   I guess moderatorziz is correct but it sounds weird to me. Do native speakers pronounce it as moderatorziz? Trying to manually sign android package with jarsigner.exe and install with adb.exe How can I do unit testing in Unity? How to implement Unit Test at Unity3D.   I wonder if it would be possible to extend the Unity editor to have some sort of testing framework in it.    Is there any guideline to implement it? Any reference like book, blog? Any working example or project? How can I make a bluish "white" LED less blue? Math mode macro in TeXstudio I want to set up a macro in TeXstudio for math mode which displays $*$ and places the cursor at position *. So far I have tried using $%|$ but upon triggering, this macro does not allow text insertion at the placeholder.  EDIT: The method above works fine if the macro shortcut is set to the default Shift+F1. However, changing the shortcut to another combination, as I would like to do, seems to be the cause of the problem. Determining possible minimal polynomials for a rank one linear operator I have come across a question about determining possible minimal polynomials for a rank one linear operator and I am wondering if I am using the correct proof method.  I think that the facts needed to solve this problem come from the section on Nilpotent operators from Hoffman and Kunze's "Linear Algebra".     Question: Let $V$ be a vector space of dimension $n$ over the field $F$ and consider a linear operator $T$ on $V$ such that $\mathrm{rank}(T) = 1$.  List all possible minimal polynomials for $T$.   Sketch of Proof:   If $T$ is nilpotent then the minimal polynomial of $T$ is $x^k$ for some $k\leq n$.  So suppose $T$ is not nilpotent, then we can argue that $T$ is diagonalizable based on the fact that $T$ must have one nonzero eigenvalue otherwise it would be nilpotent (I am leaving details of the proof of diagonalization but it is the observation that the characteristic space of the nonzero eigenvalue is the range of T and has dimension $1$).  Thus the minimal polynomial of $T$ is just a linear term $x-c$.    Did I make a mistake assuming that $T$ can have only one nonzero eigenvalue?  Thanks for your help Some websites and textbooks refer to $$\Delta x \Delta p \geq \frac{\hbar}{2}$$ as the correct formula for the uncertainty principle whereas other sources use the formula $$\Delta x \Delta p \geq \hbar.$$ Question: Which one is correct and why?  The latter is used in the textbook "Physics II for Dummies" (German edition) for several examples and the author also derives that formula so I assume that this is not a typing error.  This is the mentioned derivation:     $\sin \theta = \frac{\lambda}{\Delta y}$      assuming $\theta$ is small:      $\tan \theta = \frac{\lambda}{\Delta y}$      de Broglie equation:      $\lambda = \frac{h}{p_x}$      $\Rightarrow \tan \theta \approx \frac{h}{p_x \cdot \Delta y}$      but also:      $\tan \theta = \frac{\Delta p_y}{p_x}$      equalize $\tan \theta$:      $\frac{h}{p_x \cdot \Delta y} \approx \frac{\Delta p_y}{p_x}$      $\Rightarrow \frac{h}{\Delta y} \approx \Delta p_y \Rightarrow \Delta p_y \Delta y \approx h$      $\Rightarrow \Delta p_y \Delta y \geq \frac{h}{2 \pi}$      $\Rightarrow \Delta p \Delta x \geq \frac{h}{2 \pi}$   So: Which one is correct and why? Will my passport number change when I renew it? I'm travelling soon but need to renew my passport.  Given that I have to provide my passport number to the airline to book a flight, I was wondering if my passport number would change if I renew it.  Or would the number stay the same and the expiry date just change?  I'm asking specifically as an Australian citizen, although I suspect a 'common' answer (if there is a general way this works) might be useful too. Many To Many Relationships How to wait in a bash script for several subprocesses spawned from that script to finish and return exit code !=0 when any of the subprocesses ends with code !=0 ?  Simple script:  #!/bin/bash for i in `seq 0 9`; do   doCalculations $i &amp; done wait   The above script will wait for all 10 spawned subprocesses, but it will always give exit status 0 (see help wait). How can I modify this script so it will discover exit statuses of spawned subprocesses and return exit code 1 when any of subprocesses ends with code !=0?  Is there any better solution for that than collecting PIDs of the subprocesses, wait for them in order and sum exit statuses? The title says it all. I'd like to know how I can install software - an example is the Chromium web browser. Can a monk make a bonus unarmed attack after using shocking grasp? I'm playing a 5e Wizard/ Monk build. My DM and I are questioning the viability of the cantrip Shocking Grasp. As a monk I can do another unarmed strike as a bonus action after I attack with a melee attack. Being a touch spell, can I punch (touch) with Shocking Grasp and then do my monk's bonus action? Why does an object with a glossy shader render in black? Is it correct to sometimes capitalize words mid-sentence in computer user interfaces? Suppose $p$ is a prime number such that $(p-1)/4$ and $(p+1)/2$ are also primes. Show that $p=13$ Suppose $p$ is a prime number such that $(p-1)/4$ and $(p+1)/2$ are also primes. Show that $p=13$.   My approach:   Since $p$ is prime, it is of the form $6k+1$ or $6k-1$. Now if $p$ is of the form $6k-1$ then $(p+1)/2 = 3k$ which is not possible as $3|3k$.   So $p$ is of the form $6k+1$. Now $(p-1)/4 = 3k/2$ so $2\mid k$. So $p$ is of the form $12k+1$. But now, how to prove $k=1$?  Please help! What are tag synonyms? How can tag synonyms be distinguished from "real" tags? How are new tag synonyms created? Who can create tag synonyms?
