I am trying to create a table in a beamer class document which includes some entries in math mode. Below I provide a very minimal working example of what I am trying to accomplish: \documentclass{beamer}  \begin{document}  \begin{frame}  \begin{tabular}{cc} $n$ &amp; $m$ \\  2 &amp; 3 \\ \end{tabular}  \end{frame}  \end{document}  This code causes a fatal error to occur and no pdf file is produced. I am using texmaker with SumatraPDF. Why does this code produce a fatal error?
I have this problem where I can't built slide documents with beamer every time I include a math environment as simple as $\mu = A$. The log file posts this message at the end:  !pdfTeX error: miktex-pdftex.exe (file mathkerncmssi10): Font mathkerncmssi10 a t 657 not found  ==&gt; Fatal error occurred, no output PDF file produced!   I understand that the file (mathkerncmssi10) that is apparently missing is part of the package sansmathaccent, but the package is already there and updated.  This is driving me crazy, I would appreciate any help.    Sure, I tried this with several examples. I can post this one  \documentclass{beamer} \usepackage[latin1]{inputenc} \usetheme{Warsaw} \title[Make a LaTeX presentation using Beamer]{Introduction  to Beamer\\How to make a presentation with LaTeX?} \author{Nadir Soualem -- Astozzia} \institute{Math-linux.com} \date{Jule 13, 2007} \begin{document} \begin{frame} \titlepage \end{frame} \begin{frame}{Introduction} This is a short introduction to Beamer class. $\mu=A$ \end{frame} \end{document}    By the way, it turns out that I just tried this one in another PC and works fine.
How to compress / reduce the size of JPEG photos for archiving? I have 50,000 high resolution JPEG photos, where a couple of them might occasionally be needed, about once a year.  I wanted to zip them to save disk space, except that zipping gives no space benefit - so trying to reduce the images disk usage using winzip, winrar or 7zip was not successful.  Is there any software or algorithm similar to zip to compress image size on hard disk for storage without loosing any image information? Creating additional Virtual Host Ubuntu Server Invoking Java main method with parameters from Eclipse During development (and for debugging) it is very useful to run a Java class' public static void main(String[] argv)  method directly from inside Eclipse (using the Run As context menu).  Is there a similarily quick way to specify command line parameters for the run? What I do now is go to the "Run Dialog", click through the various settings to the tab where I can specify VM and program arguments and enter them there.  Too many steps, plus I do not want to mix the more permanent runtime configuration settings with the one-off invokation parameters. What I want instead is to check a box somewhere (or have a separate menu item "Run as Java application with command line") and then be prompted for the commandline every time (with a nice history). Probability that 2 appears at an earlier position than any other even number in a permutation of 1-20 Suppose we uniformly and randomly select a permutation from the 20! Permutations of 1,2,3,...,20. What is the probability that 2 appears at an earlier position than any other even number in the selected permutation?  My approach :   2 in first position ==> 1*19! (1 is the position of 2)  2 in second position ==> 10 *1 *18!  2 in third position ==> 10*9 *1 *17!  . . .  2 in 11th position ==> 10*9*8*7*6*5*4*3*2*1*1*9!  But this was asked as a multiple choice question in GATE 2007 and the options were  (A) 1/2   (B) 1/10  (C) 9!/20!  (D) None of these  I am not able to reduce this analysis to a given option. Get driving directions using Google Maps API v2 Is the EmDrive, or "Relativity Drive" possible? In 2006, New Scientist magazine published an article titled 1 [] about the  [] which stirred up a fair degree of controversy and  that New Scientist was engaging in pseudo-science.   Since the original article the inventor claims that a "Technology Transfer contract with a major US aerospace company was successfully completed", and that papers have been published by Professor Yang Juan of The North Western Polytechnical University, Xi'an, China. 2   Furthermore, it was  that the Chinese were going to attempt to build the device.  Assuming that the inventor is operating in good faith and that the device actually works, is there another explanation of the claimed resulting propulsion?  Notes:  1. Direct links to the article may not work as it seems to have been archived. 2. The abstracts provided on the  website claim that they are Chinese language journals which makes them very difficult to chase down and verify. I have a question about the following text:     Last week Alex Knapp at Forbes published an article criticizing my Nikola Tesla comic. I don't normally respond to these kinds of thing, but since it's' Forbes I figured a proper response was in order.    I would rather say "this kind of things" rather than the version in the text above. Illustrator - my rectangles are all sheared skewed? When I try to create a rectangle in a certain .ai file they all come out sheared:    but this isn't the case in other projects.  Is there any way to fix Is history expansion disabled in scripts? I understand the following error is due to ! used for history expansion:  $ echo "Hello!Tim" bash: !Tim: event not found   However if I put the command into a script and run the script, there is no problem:  $ cat myscript echo "Hello!Tim" $ bash myscript  Hello!Tim   Why is that? Does the bash manual mention the reason? How to create Mist in Blender Electricity takes the path of least resistance? Electricity takes the path of least resistance!   Is this statement correct?    If so, why is it the case?  If there are two paths available, and one, for example, has a resistor, why would the current run through the other path only, and not both? If I had a very shallow question, then I am sorry. $x,y,z\in\mathbb{N}^{+}$ and$$\frac{x}{y+z}+\frac{y}{x+z}+\frac{z}{y+x}=4$$find $x,y,z$.  I try with AM-GM, just get$$ \frac{x}{y+z}+\frac{y}{x+z}+\frac{z}{y+x}\geq\frac{3}{2}$$  This means that the equation must have a real solution, but can not be sure there is an integer solution.  Let: $x=ay=abz$, then the equation becomes:$$\frac{ab}{a+b}+\frac{b}{ab+1}+\frac{1}{a^2+ab}=4$$  Which makes the problem become non-homogeneous, and seems to become more difficult. I have no more ideas. Could anyone help me? Thanks a lot. The bevel depth (the radius of the tube) is set to 9cm but it actually isn't when compared to the background grid. This is is confirmed by importing it into sketchup and scaling it to the proper units it turns out the radius is only around 2.286cm. This problem only shows up on certain projects. What's wrong and how do I fix it?  (sorry that I can't upload the file, it's a long story) What if the universe is rotating as a whole? Could it be that Goldbach conjecture is undecidable? The result closest to Goldbach conjecture is Chen's theorem [Sci. Sinica 16 157–176], the proposition ``1+2''. It is natural to ask if it is likely that under our arithmetic axioms the Goldbach conjecture is an undecidable proposition.
