Using the suggestion from , I used the \sqrt sign from Asana Math with TeX Gyre Pagella Math to decrease the height of some inline math. However, this apparently had some unintended side-effects. Take this minimal example:  \documentclass[a4paper, 12pt]{scrreprt}  \usepackage{unicode-math} \setmainfont{TeX Gyre Pagella} \setmathfont{TeX Gyre Pagella Math} % comment or uncomment the next line and compare the output \setmathfont[range=\sqrt]{Asana Math}  \begin{document}  \[     \int ∫ \sum \]  \end{document}   If you compile with or without the line \setmathfont[range=\sqrt]{Asana Math}, the size of the integral sign (but not the sum sign!) changes!    What gives? The integral sign for TeX Gyre Pagella Math is very small to begin with, so this is really uncalled for! Is this a bug? Are there any more unexpected side-effects? How can I avoid this and keep both the \sqrt from Asana Math as well as the bigger integral sign?  For reference, I'm using the version of LuaLaTeX from the Ubuntu 15.04 repositories  (it says "This is LuaTeX, Version beta-0.79.1 (TeX Live 2015/dev/Debian) (rev 4971)").
You can use the range feature of unicode-math to set the math font for a specific unicode slots or the macro accessing the glyph. I tried this with the sum sign &amp; Latin Modern, see my example:  \documentclass{scrartcl}  \usepackage{amsmath} \usepackage{unicode-math} % use unicode in math &amp; setup math fonts \setmathfont{Asana Math} %\setmathfont[range=\sum]{Latin Modern Math} % substitute Sum sign  \begin{document}  Notice the different sum sign $\sum$, as intended.   Notice also, the difference in spacing, not intended: \begin{equation}     \begin{bmatrix}         0           &amp; \frac{1}{2}   &amp; \frac{2}{3} \\         \frac{3}{4} &amp; 0             &amp; \frac{4}{5} \\         \frac{5}{6} &amp; \frac{6}{7}   &amp; 0     \end{bmatrix}     \begin{pmatrix}         A \\         B \\         C     \end{pmatrix} \end{equation} \end{document}   However, not only the sum sign, but also the spacing in the matrices changes. With Latin Modern commented out (as in the example):  With Latin Modern active (remove % before relevant line):  Why is that? BTW, I'm using Lualatex from TeXLive 2012.

In the iOS app, pulling up a question from the feed gives the standard question view, which provides no means of navigating elsewhere on that site, either to browse or search. This should be changed for feed questions.  For example, I tapped on a highlighted Seasoned Advice question today, and found that I wanted to make a comment pointing to a related question on the site. The best way I could think of finding that post was to leave the app and use my browser. Then I came back with the link to copy-paste in.  Similarly, a question in the feed might be so intriguing that I want to look around for more cool stuff on the site. That requires two taps back and then a search via the "All Sites" menu item.  I'd suggest that questions selected from the feed should get a special header bar (or maybe stuck in between the questions and the answers) that provides a "More posts!" link at least to the site's top view; ideally there would also be a search field that could pop out of it.  Another possibility that would work pretty well, although it's a small tap target on a phone, would be to link the site name that appears under the question title to the site's top view. Can $\sqrt{n} + \sqrt{m}$ be rational if neither $n,m$ are perfect squares? Can the expression $\sqrt{n} + \sqrt{m}$ be rational if neither $n,m \in \mathbb{N}$ are perfect squares? It doesn't seem likely, the only way that could happen is if for example $\sqrt{m} = a-\sqrt{n}, \ \ a \in \mathbb{Q}$, which I don't think is possible, but how to show it? Low wifi signal in 14.04 LTS How to detect if a variable is an array How can I make subsections lose the section number within the section and gain the section number outside it? For a paper I am typesetting, the author wants subsections to be written with single numerals.  So far, OK,   \renewcommand{\thesubsection}{\arabic{subsection}}   does the job.  Yet frequently, he wants to cite the subsection in a later section, and wants both section and subsection numbers in references; i.e., he wants to quote Section 1.1 from Section 2.      My current workaround is to give both the section and subsection numbers in the reference.   MWE  \documentclass[11pt]{amsart} \usepackage{hyperref} \usepackage[backend=bibtex,citestyle=alphabetic]{biblatex} \renewcommand{\thesubsection}{\arabic{subsection}}  \begin{document} \section{A section} \label{sec:first} \subsection{A subsection} \label{subsect:first} Something cool. \section{New section} Now I want to cite the coolness in Section~\ref{sec:first}.\ref{subsect:first}. \end{document}     This works fine, except that the hyperref is set up so that if you click on the first 1, you go to Section 1, not Subsection 1.  Yet I would prefer that both numerals go to the same place in the hyperref links.       I could just wrap each such citation in \renewcommand{\thesubsection}'s, but is there  an easier way to add section numbers when citing subsections from a different section?

Do the other continents suffer those long winters?  Can the Others harm the other continents?  In The Lord of the Rings there were other realms than Middle-earth, but Middle-earth was still all of humanity and dwarf population and hobbits.  Sure there are stories like Romeo and Juliet where the only thing that matters is whether those 2 are going have a chance to love.  But in these fantasy / sci-fi stories there's usually danger of world domination by evil.  It's not usually just one continent is going to be a terrible (or impossible) place to live but other civilizations will flourish. Letter class alternatives with support for figures, tables, and labels Desktop link to Eclipse I was tring to install eclipse on ubuntu. What I did: I unzipped the tar archive of eclipse. I tried to start eclipse from the command line - like this - ./eclipse. It works. But then I tried to create a desktop icon with: gnome-desktop-item-edit ~/Desktop --create-new. In a new icon I showed the path to the eclipse executable which I could launch from the command line. But then eclipse does not start stating:  A Java Runtime Environment (JRE) or Java Development Kit (JDK) must be available in order to run Eclipse. No Java virtual machine was found after searching the following locations: /home/artem/eclipse/jre/bin/java java in your current PATH   The same message appears if I try to launch eclipse by double-clicking its original launcher. So it starts from the terminal but not from the desktop (it does not start when double-clicked) And also I get a message in the terminal (at some stage it appeared):  (gnome-desktop-item-edit:8998): Gtk-WARNING **: Attempting to store changes into `/root/.local/share/recently-used.xbel', but failed: Failed to create file '/root/.local/share/recently-used.xbel.DSV8LW': No such file or directory   I am using Ubuntu 12.04 x32 and eclipse Juno.

What do the supercharges in  do?  In ${\cal N}=1$ supersymmetry there are a certain number of fermions and and equal number of bosons. You can transform all fermions to the bosons (and vice versa) in a 1 to 1 fashion using a single supercharge, $Q$.  So what happens when you have, for example, ${\cal N}=2$ supersymmetry with 8 supercharges? Since $Q$ is a generator of supersymmetry transformations, is it a linear combination of these supercharges that act on the particles? In which case could one particle be acted on by two separate linear combinations of $Q$? Or is it strictly one linear combination of $Q$ per fermion/boson?  Also, what does ${\cal N}$ mean physically? What difference does ${\cal N}=2$ have to ${\cal N}=1$ other than more supercharges? Or is that the only difference between the two theories?
