I am writing on behalf of someone else.  But the question will be easier to pose if I put myself in his shoes and speak in the first person.  I will soon graduate with a Bachelor's in economics and mathematics in a Third World country.  I have, however, also studied physics. I actually have more physics than mathematics courses on my transcript.  I want to study for a PhD in mathematical physics in the U.S. I would need support (e.g. TAship).  Where I live, subject GREs are only offered once a year, and one is not permitted to take two different ones on the same day.  It is too far and expensive for me to travel to another country to take a second subject GRE.  Suppose, for the purpose of this question:   I decide to take the Physics GRE, and apply to physics departments I get admission to a physics department, and a TAship I take a combination of both math and physics courses and do well After several semesters I realize I'd rather that my home department were math, instead of physics      How hard would it be to apply to switch over to a math department (either in the same university, or a different one), assuming I had taken sufficient math courses, and done very well in them?   Note: The  is somewhat helpful, but I would like to see a specific focus on the math/physics interface; also, please consider the specific option of pausing at completion of a masters, with a switch of department at that point.
Is it possible to switch from one area of graduate study to another in US universities? For example, suppose someone has enrolled in a computer science phd program. Can he switch over to math(or physics) phd program in the same school later?(or say from applied mathematics to pure mathematics?)  What are the steps for doing for doing that?
How can this English sentence be translated into a logical expression? ( Translating " unless") You cannot ride the roller coaster if you are under 4 feet tall unless you are older than 16 years old.   Let:   $P$ stands for "you can ride the roller coaster" $Q$ stands for "you are under 4 feet tall" $R$ stands for "you are older than 16 years old"   Is this logical expression correctly translated?  $$P \rightarrow (Q \wedge R)$$ When should I upgrade my camera body? Why a mono-atomic crystal layer (2D) can't be stable? According to Peierls and Landau, 2D crystals were thermodynamically unstable. They can't exist! Of course, this theory was disapproved in 2004 (example: graphene).  What is the general definition of stability of a general system?  What is the thermodynamics' stability?

Over time I realized a very annoying property of the Stack Overflow reputation system: Easy answers to popular question are rewarded with a lot more reputation points than actually great answers. In case anybody actually needs examples for this, here are two examples from :   gained me 420 rep, I invested 2 minutes writing it, and it only was a wild guess.   took me about an hour for the research and the math and gained me 40 rep.  Now I know that you are bound to get more rep for answers that are useful to more people, and I'd say that's fine. But the current situation is quite extreme: 30% of my reputation is from 5 of my 330 answers, and they are definitely far from being my best ones.  A final example that is not from my profile, but more extreme: Do you really think  is worth 40000 reputation?  My proposition to improve that situation would be to make the reputation gain from a single answer non-linear, maybe even have it capped at a certain point. I'm not sure on how that non-linear function should look exactly, and would leave good proposals for that to users with more experience than me. How to put legend below the chart? I have the following code that produces a line chart:  \begin{figure}[p]     \centering \begin{tikzpicture}     \begin{axis}[     use units,     cycle list name=exotic, %This defines the color. It produces nicer colors         width=15cm, height=8cm,     % size of the image         grid = major,         grid style={dashed, gray!30},         %xmode=log,log basis x=10,         %ymode=log,log basis y=10,         xmin=0,     % start the diagram at this x-coordinate         ymin=0,     % start the diagram at this y-coordinate         %/pgfplots/xtick={0,5,...,60}, % make steps of length 5         %extra x ticks={23},         %extra y ticks={0.507297},         axis background/.style={fill=white},         ylabel=Time,         xlabel=Number of Datapoints (n),         y unit=s,y unit prefix=m,         tick align=outside]        % import the correct data from a CSV file       \addplot table [col sep=comma,trim cells=true,y=Best Case (Ascending)] {datasets/time_mergesort.txt};           \addplot table [col sep=comma,trim cells=true,y=Average Case (Random)] {datasets/time_mergesort.txt};                     \addplot table [col sep=comma,trim cells=true,y=Worst Case (Descending)] {datasets/time_mergesort.txt};                      \legend{Ascending,Random,Descending}     \end{axis}  \end{tikzpicture}     \caption{Mergesort Run Time for Sorting Random Data}     \label{fig:merge_sort_from_csv} \end{figure}   And at the moment the legend appears on the chart on the upper right corner. I need to move that below the chart, or even to leave that on the chart but to move that on the upper left corner.   I have tried the solution mentioned at , but it did not work for me.  How can I move the axis in a different position? Can I enter Croatia with single entry visa Schengen? I've seen the word static used in different places in C code; is this like a static function/class in C# (where the implementation is shared across objects)? Copying unicode symbols from Firefox address bar as is Let's say I open a webpage with some Unicode characters, say, Cyrillic, in the address like this:        When I try to copy it from the address bar somewhere else, it becomes unreadable rubbish:        I guess this is for compatibility. However for readability I want to copy it straight away with proper Unicode characters.  What and how should I tweak to make that possible?  Edit: The answers are good, but they are hacky. Are there any settings in about:config? Taxonomy count per Post type Below is the code i use to output the post tag (taxonomy) count/number. I want to be able to split the count based on post type that the taxonomy features in (rather than the total number).   So i have the default "post" Post type, aswell as "blogs", &amp; "pics". I want the taxonomy count to display something like: x posts | x blogs | x Pics              &lt;?php             $tags = get_tags( array('name__like' =&gt; "a", 'order' =&gt; 'ASC') );             foreach ( (array) $tags as $tag ) { ?&gt;                 &lt;li&gt;                                                 &lt;a href="&lt;?php echo get_tag_link( $tag-&gt;term_id ) ?&gt;"&gt;                                   &lt;span class="name"&gt;&lt;?php echo $tag-&gt;name ?&gt;&lt;/span&gt;                         &lt;span class="number"&gt;&lt;?php echo $tag-&gt;count ?&gt;&lt;/span&gt;                     &lt;/a&gt;                 &lt;/li&gt;             &lt;?php } ?&gt; I have a VF page built on Lightning Design system (LDS) framework. When I add the renderAs="PDF" attribute, pdf does not show the content with LDS CSS/Style.  Reference Link:   Note1: apex:page tag has all the usual attributes which is required for pdf *     (showHeader="false" sidebar="false" standardStylesheets="false"   docType="html-5.0" applyHtmlTag="false" applyBodyTag="false")   Note2: Salesforce supports external stylesheet. That is, CSS file stored in Static resource. Link of example:   I also copied the whole css content from the LDS CSS file (Path: 'assets/styles/salesforce-lightning-design-system-vf.min.css') and applied as inline CSS in VF page. But still, there is no luck.  My styleSheet is referred in VF page as below  apex:stylesheet value="{!URLFOR($Resource.SLDS221,      'assets/styles/salesforce-lightning-design-system-vf.min.css')}"   Page works absolutely fine if it is not rendered as PDF.

Unfortunately during testing I deselected the sysadmin rights for my login and now can't readd it (because I don't have sysadmin rights).  There are no other sysadmin accounts for the instance except SA.  I was set up for just Windows Authentication so I hacked the LoginMode in the registry to 2 so I could login as SA using Sql Authentication. This does indeed set the login mode to Mixed, however the SA user is disabled by default and I can't reenable it because I am don't have sysadmin rights.  How do I enable the SA login so I can get in and reassign the sysadmin to my normal account? Is there a registry setting for this too or is it stored in the master database?
