How did Groot manage to raise the axe of Thor when even Hulk failed? In Avengers Hulk tried to raise Thor's hammer and failed miserably. In Avengers: Infinity War, Groot raises Thor's new axe and holds it for a few seconds! Is the axe made of some other light material, or is Groot stronger than Hulk?

How Special Relativity causes magnetism Why is King Arthur female? Why is Iskander tall? I've watched both the Fate/Zero and Fate/Stay Night anime (including the Unlimited Blade Works movie), but none of the visual novels, so no spoilers from that unless they are light spoilers. One thing that bothered me was that despite the fact that heroic spirits are defined by the public opinion/view of them, some heroes had qualities that were in direct opposition of what the public thought.  We know that heroic spirits, being sealed on their Throne of Heroes, are meant to be completely unchanged. This is the entire point of the Throne of Heroes. But this seems to be in opposition of the previous fact that heroic spirits are defined by what others think they are. Then there are Counter Guardians who are completely different, I believe, in that they are not sealed on their Throne of Heroes.  One particularly important Counter Guardian of the series is Arturia, or Saber. Arturia is female, despite the fact that she was treated by even her contemporaries as male, and has gone done in history as male. In fact, there isn't even any small hint as to Arturia's gender being anything other than male in our history, or the history of the Nasuverse (I believe). This being true, shouldn't Arturia be male?  This not being the case shouldn't Arturia be erased, or else create instability in the World? Same with Iskander. In history he is known for being pretty short, even for a Macedonian. That he is very tall means there is an incongruity with human knowledge and true fact.  Furthermore, in the Unlimited Blade Works movie Archer is revealed to be Heroic Spirit Emiya. If Heroic Spirit Emiya is summoned before he is even a hero, or acquired his gift from the World, etc., then how is it that Heroic Spirit Emiya is even strong at all? The power of a Servant being based on their popularity at the time of their summoning, Emiya should be weaker than pretty much every other Servant, and then some.  Maybe I'm just over-analyzing things, or I have some misconception. In any case, answers are appreciated. I'm using latex on a small netbook, and with average-sized files (~150 pages at the moment) compilation is already pretty slow. So I am looking for every way to speed up the compilation.  In this search, I found  explaining how to "precompile a preamble", or, latexically-speaking, how to make a custom format file. That works fine enough.  But my preamble isn't as static as it should be, I keep adding or modifying definitions in there. To mix the two solutions, at the moment, I use a Makefile together with latexmk, the makefile handling the regeneration of the .fmt file if needed, and latexmk taking good care of the rest.  But I have two problems with this :   integration with emacs to compile the whole document when working on a single file (make needs to be called in the proper directory) latexmk doesn't recompile the file every time the preamble is modified, because it doesn't count as a dependency.   So I'd like to find a way to get rid of this Makefile, and get all the stuff done by latexmk.  I edited my .latexmkrc to include this :     pdflatex = 'pdflatex -fmt main %O %S';  add_input_ext('pdflatex','fmt');  add_cus_dep('tex', 'fmt', 1, 'compilepreamble'); sub compilepreamble {     print "Preamble compiling...\n";     $command = '&amp;.pdflatex ./fmt/preamble.tex\dump';     system("pdflatex -ini -jobname='$_[0]' '$command'"); };      But with this, if the file main.fmt is not present or if fmt/preamble.tex is updated, the main.fmt file won't be regenerated. Actually, in the first case, I get an error from pdflatex saying the it can't find main.fmt format file. So I understand latexmk doesn't even try to build main.fmt, it's probably not a problem in my custom dependency. However, I think I've added everything necessary for this to work.  So... Did I forget something? Is there a way round? Or is it a hopeless quest? To start in or at a company? I am not sure about what is right:     I can start my career at an international company.   or     I can start my career in an international company.   For me at sounds appropriate? Are if else statement equivalent to logical and && or || and where should I prefer one over the other? I'm learning about decision making structures and I came across these codes:  if [ -f ./myfile ] then      cat ./myfile else      cat /home/user/myfile fi   [ -f ./myfile ] &amp;&amp; cat ./myfile || cat /home/user/myfile   Both of them behave the same. Are there any advantages to using one way from the other? How do I correctly tag my questions? Here are some tips for tagging questions.

I understand monsters only spawn in a 9 x 9 grid of chunks centered on the player, and I assume they stay around while they remain within that distance of you. But do they despawn as soon as you move away from them? Or do they remain? If so what (if anything) causes them to despawn? Are the rules any different for passive mobs?  Will running far away from an area and then coming right back clear it of monsters? I'm looking for some insight into how Stack Overflow releases are deployed and managed.   What software/tooling is used? What time are releases generally performed? How many and what steps are involved?   I'm assuming it's not too stringent given the light team working on the codebase. But considering the high rate of change, I could see some kind of tooling and automation becoming increasingly relevant, so I'm curious to learn what kind of decisions are being made to deal with the changes in scale and feature set over time.  Is this information available somewhere? Should I disable swap file if I have lots of RAM or should I move it to a virtual RAM drive? Imagine I have tons of RAM. Let's say 64GB. That's a lot for even gaming PCs. Now the default location of a pagefile in Windows is on the main OS drive, be it HDD or SSD, which are faster in general, but still not as fast as RAM.  Something tells me that disabling the pagefile on the hard drive or creating a virtual RAM drive and letting the pagefile be there could make Windows move all its virtual memory to RAM, and so increase the system's performance, but I'm not very knowledgeable in that area, so that might not be true at all.  I tried both, but I couldn't analyze the results to reach a definite conclusion with my knowledge level in memory things.  Would this work? If not, why? How can I wake-up a PC using a command? (i.e. equivalent to moving a mouse, etc) It doesn't seem like this would be very difficult, but how can I wake-up a PC by doing the equivalent of moving a mouse or pressing keys on a keyboard?  My PC is running Windows 10 and I only have the monitors enter sleep mode after 15 minutes.  The rest of the PC is still awake and doesn't use hibernate, etc.  I'm trying to use EventGhost to receive a TCP/IP command that tells the PC to wake up the displays but it's proving quite difficult. A inequality proposed at Zhautykov Olympiad 2008 An inequality proposed at Zhautykov Olympiad 2008.     Let be $a,b,c &gt;0$ with $abc=1$. Prove that:    $$\sum_{\mathrm{cyc}}{\frac{1}{(a+b)b}} \geq \frac{3}{2}.$$   Set $a=\frac{x}{y}$, $b=\frac{y}{z}$, $c=\frac{z}{x}$.   Our inequality becomes: $$\sum_{\mathrm{cyc}}{\frac{z^2}{zx+y^2}} \geq \frac{3}{2}.$$  Now we use that: $z^2+x^2 \geq 2zx.$ $$\sum_{\mathrm{cyc}}{\frac{z^2}{zx+y^2}} \geq \sum_{\mathrm{cyc}}{\frac{2z^2}{z^2+x^2+2y^2}} \geq \frac{3}{2}.$$  Now applying Cauchy-Schwarz we obtain the desired result.  What I wrote can be found on this link: . But now, I don't know how to apply Cauchy-Schwarz.   Thanks:) I'm curious to see some real examples of where simply capturing the same photo in RAW (and being processed by someone who can do it justice) has significantly improved the photo at the end of the process.  I understand what RAW is and why you might want to use it over JPEG, however, I'd like to actually see some examples where it has allowed for a better result. More control over tone, conversion from the more detailed data to 8-bit RGB etc.  Does anyone have or know of some processed RAW+JPEG shots for exact comparison? I was wondering if someone could critique my argument here. The problem is to find the probability where exactly 2 people in a room full of 23 people share the same birthday.  My argument is that there are 23 choose 2 ways times $\displaystyle \frac{1}{365^{2}}$ for 2 people to share the same birthday. But, we also have to consider the case involving 21 people who don't share the same birthday. This is just 365 permute 21 times $\displaystyle \frac{1}{365^{21}}$. To summarize:  $$\binom{23}{2} \frac{1}{365^2} \frac{1}{365^{21}} P\binom{365}{21}$$ Flash plugin up to date but Firefox keeps telling me that I have the old version
