I have written a professor who has an available Ph.D. position with my CV. After 3 days the professor replied with an apology for being late and said she went through my CV carefully and my work aligns very well with the project she is offering. She asked me to apply for the scholarship. Also asked if I would like to discuss the project with her in zoom or skype. I replied to her that I am interested. Its been a week that she did not write me back. Is it ok to write to her again? If yes, how to address it?
When needing to ask a professor about something important and potentially delicate, what is an appropriate way to phrase the question or write the email?  Examples include:   Requesting a recommendation letter Asking for exceptions to policy (e.g., ignoring a course prerequisite, rescheduling an exam) Asking if you can do research with them, join a group, get into a program Scheduling a meeting, exam, or defense Letting them know about a change of plans Letting them know about a life event affecting your work or studies (e.g., wedding, funeral, sickness, vacation)
Let $S=\{\frac{m}{2^n}| n\in\mathbb{N}, m\in\mathbb{Z}\}$, is  $S$ a dense set on $\mathbb{R}$? Do an action and its Euler-Lagrange equations have the same symmetries? Assume a certain action $S$ with certain symmetries, from which according to the Lagrangian formalism, the equations of motion (EOM) of the system are the corresponding Euler-Lagrange equations.  Can it happen that the equations of motion derived by this procedure have different kinds and/or numbers of symmetries than the action one has started with? And if yes, are there underlying principles that state why which kind of symmetries the action does not have can emerge in corresponding EOMs or which kind of symmetries of the action can potentially disappear in the EOMs derived from the Euler-Lagrange equations?

I am told that the latter is accurate because all of the jury do not have the same opinion in the particular case. Then, how does the subject verb agreement fit in 'The jury is still out' ? I mean, 'The jury is out' would allude to a situation were the opinion on a matter is (are?) still divided. 15V 3A dc motor PWM frequency setting What is a suitable frequency for 15V/3A DC motor?

Where is the usage of Ubuntu cloud guest image on OpenStack documented? I can't execute newest Blender 2.80, it says that I need a graphics card that supports OpenGL 3.3 or higher ERROR: A graphics card and driver with support for OpenGL 3.3 or higher is required  Processor: AMD A6-3670 APU with Radeon(tm) HD Graphics, 2695MHz BIOS Version: HPQOEM - 1072009 Dedicated GPU:   This is a very old PC, but when I search online it seems that theoretically Blender 2.8 should run since my openGL is 4.4 If banks offer a fixed rate lower than the variable rate, is that an indication interest rates may head down? This is one of the major banks in Australia:   At present time, the variable rate is 7.80% but the fixed rate is 6.99% for one year.  And it seems most banks in Australia, if you fix the rate (at the moment), you will get a lower rate.  Is this an indication that in the eyes of the banks, that they believe the interest rates are going to down? I just ask because it seems most people in the media think the rates are going up and they've risen about 6 times in a row now.  Could it be that the banks are secretly preparing for rates to drop? Was Quirrell the Defense against the Dark Arts teacher for more than one year? It's well seen throughout the series that there is a “curse” on the DADA teacher position, that no one can hold that post for more than a year. But it seems like Quirrell has been around for longer than a year. What's up with that? Is there any research or data on horizontal vs. vertical navigational menus? I've seen many sites using both horizontal (top) navigation, vertical (left) navigation, and both across web sites for a long time. My understanding is that they're both conventions, but I would assume there must be some data out there supporting one route over the other.   My question is: are any studies or data for or against horizontal or vertical navigation (as suggested above) with regards to primary navigation (specifically on a smaller site or web app).  I've read some interesting things that are flipping me back and forth between liking horizontal more than vertical and vice versa. For example if you look at Jacob Nielsen's post on  you get the feeling that more important content should be on the left -- but you could take that as it being more important for the navigation (the user's escape routes) to be in that valuable space. Find the infinite sum $\sum_{k=1}^{\infty}\sqrt k - 2\sqrt {k + 1} + \sqrt {k + 2} $ I am facing a problem, where I have to find the partial sum of a sequence/sum and with that, the infinite sum of the sequence.  $\sum_{k=1}^{\infty}\sqrt k - 2\sqrt {k + 1} + \sqrt {k + 2} $   The problem here is that I don't know how to proceed. I would be thankful if someone would steer me in the right direction. Usage of -n and -z in test built in - Bash What is the best way to return an error from a function when I'm already returning a value? When I try to print a Unicode string in a Windows console, I get an error . UnicodeEncodeError: 'charmap' codec can't encode character .... I assume this is because the Windows console does not accept Unicode-only characters. What's the best way around this? Is there any way I can make Python automatically print a ? instead of failing in this situation? Edit:  I'm using Python 2.5.

Downloading multiple files with youtube-dl I use youtube-dl to download files from YouTube. I have tried downloading multiple files, but it is not working out for me.
