Figures won't stay where they should using LaTex
How to influence the position of float environments like figure and table in LaTeX?
Unsized array declaration in a struct Einstein-Cartan theory - Book recommendation I want to delve into Cartan's formulation of General Relativity but it don't really know where to look. Does anyone have any book suggestions? Are we inside a black hole? I was surprised to only recently notice that      An object of any density can be large enough to fall within its own   Schwarzschild radius.   Of course! It turns out that supermassive black holes at galactic centers can have an average density of less than water's.  Somehow I always operated under the assumption that black holes of any size had to be superdense objects by everyday standards.  Compare the Earth to collapsing into a mere 9mm marble retaining the same mass, in order for the escape velocity at the surface to finally reach that of light.  Or Mt. Everest packed into one nanometer.  Reading on about this , it increases proportionally with total mass.  Assuming matter is accumulated at a steady density into a spherical volume, the volume's radius will only "grow" at a cube root of the total volume and be quickly outpaced by its own gravitational radius.  Question: For an object the , what would have to be its diameter for it to qualify as a black hole (from an external point of view)?  Would this not imply by definition that:   The Earth, Solar system and Milky Way are conceivably inside this black hole? Black holes can be nested/be contained within larger ones? Whether something is a black hole or not is actually a matter of perspective/where the observer is, inside or outside? Prove previsibility and $E[X_{T \wedge n}] \le E[X_{S \wedge n}]$ The maximum energy stored by a capacitor is when it’s (theoretically) fully charged, or just before it reaches dielectric breakdown, if you will. It seems, then, that the maximum energy ($E$) $=QV$, where $Q$ is the maximum charge attained and $V$ is the maximum ‘voltage’. However, the correct equation for the maximum energy is $E=\frac{1}{2}QV$. Why? I’m looking for a simple, intuitive explanation because my reasoning that $E=QV$ seems sound to me. I know about , but I’m looking for a reason to disprove my specific argument that $E=QV$ and not the “Oh, it comes from integration.” response. Expected prediction error - derivation How do I change my default browser? Is there an option to change my default browser for all my applications? In the comedic music video  there are many clips of vintage scifi films, some of which I recognize.  This one however, of a large blue floating holographic head talking to some kind of military installation does not look at all familiar.  Does anyone recognize this film? Every proper ideal is contained in a maximal ideal, in a commutative ring with identity. The statement is:     In a commutative ring with 1, every proper ideal is contained in a maximal ideal.   and we prove it using Zorn's lemma, that is, $I$ is an ideal, $P=\{I\subset  A\mid A\text{ is an ideal}\} $, then by set inclusion, every totally ordered subset has a bound, then $P$ has a maximal element $M$.  My question is why $M$ must contain $I$? Local server updates for the network I have setup one computer on our network as the file server. Because Internet here in Tanzania is both slow and expensive I would like that one system to download all the updates and then the other 10 computers on the network to get those update files from the server. I'm a bit of a noobie to Ubuntu, but really want to learn how to get this working smoothly so as to help other NGOs and schools here in Tanzania. Brendon If $x\sqrt{1+y}+y\sqrt{1+x}=0$ find $y'$ When studying weak border conditions (in Sobolev Spaces), the usual motivation for the weak meaning of inequalities is that the boundary of most open sets in $\mathbb{R}^n$ has zero Lebesgue measure. But is there any open set $U\subseteq\mathbb{R}^n$ such that it's boundary has positive Lebesgue measure? I really can't think of anything like that. What is the best way to handle a lot of misused tags? So today I noticed a question that had the  tag. As the question was not about JSFiddle, and only included a link to the site, I thought somebody has just created this for the sake of it. So I decided the best action would be to remove it, and try to stop it from getting out of control.  But then I searched (clicked the tag) for other questions that used it and I was amayonaised to see over 500 questions had the very same tag! Most of which were incorrectly tagged. So I cleaned up a couple and then quickly got bored.  So I am wondering, aside from going through them all by myself, is there a more efficient way?  I think it would be a great idea if there was some feature (probably an admin feature) that allowed a new tag queue to be added to the review list. I think this could work well as follows:   Somebody brings up the problematic tag in question (e.g. Me on here) An admin reviews my concern, and decides that the tag is very misused That admin adds the tag for review in a (temporary) new review queue. All users that can review can then go through existing tags, and vote for "No action" or "Remove tag" The world becomes a slightly better place   ...or not?    By the way, I tried to add some new tags to this post but I don't have the rep. So if someone could create them for me that would be swell: "musefan", "today", "sunny-spells", "pointless-tags" When I view most glass from the side it's green which I've found out is due to impurities in the glass specifically from iron oxide. Why is it when I view the larger face from an oblique angle, it isn't nearly as green? I cannot personally notice any different on the piece I have next to me even when I hold it at an angle that would be almost looking at the edge of the glass. It is pretty small (about 2.5" x 5" x .0625" or about 61mm x 127mm x 2mm, l x w x h) but I feel like it's big enough that I'd be looking through enough glass to get the green. Nesting block level elements inside the  tag... right or wrong? What is the subject of this sentence I've seen this sentence in someone's facebook status but it sounds unnatural to me.     I'm the Rumplestiltskin who spins straw into gold   I thought it should be spin because the subject is I, but I'm not sure. Which one is the subject in this sentence, I or Rumplestiltskin and why?
