i was reading  after hearing about it on the news, while reading i saw the term "floaters" which made me remember of a recent Family Guy Episode in which there is a joke about them in Peter's vision.  I am wondering, what exactly are they? what is their technical term? and is it possible to remove them permanently (apart from the obvious gouging out your eyes).
I have noticed that if you look directly at tubelight (I have only white ones in my home) and close your eyes little, you see little random shaped colourless things sometimes with slow speed and sometimes with falling down.   They are shaped like circles with something in between and in chains of random length.   My father has also seen them. So, I am sure I am not imagining things. What the hell are they?
Do I need a UK visa? How and where to apply? I live in Germany since May 2013 as a spouse of German citizen. In Nov 2015 we divorced and I have German residence permit till Jan 2018. We have a son in this marriage and legally I have the right to live in Germany indefinitely. I would like to visit my brother and sister who are British citizens living in UK. What is the visa procedure for me to travel to UK for a week.  Do I need a visa to enter UK ? Are film capacitors affected by DC bias? Press-and-hold or Long-Press Gestures: Unintuitive? Often, I find people struggle with the usage of press-and-hold gestures on mobile/web platforms. The mere thought of having a user press on a defined object and hold for an arbitrary amount of time before the product reacts seems overtly complicated and unobtrusive. My questions are:   For what use cases do press-and-hold gestures best fit? Have there been published studies with regards to press-and-hold gesture intuition? Are there more viable alternatives to this system? Escape velocity from long ladder Can there be no 'a' between such and a noun? When it comes to losing weight, a quick fix to would be nice, but we   know there’s no such [a] thing. ()   It sounds like there isn’t ‘a’ in the news. So I wonder if it be right when there is no ‘a’ after ‘such.’ Would it be okay? I need a number of different full-page DOM samples for my qUnit test suite How can we prove charge invariance under Lorentz Transformation? ModernCV Remove horizontal line in sections I want to write my cv with moderncv-Classic style. Can you tell me, how I can remove the horizontal line in the left of each section? how can I find sum of series $ \sum_{n=1}^{\infty} (n\cdot \ln \frac{2n+1}{2n-1} - 1) $? It is so weird for me because I put this to Mathematica and it tells me that sum does not converge...  Let consider sum no to infinity, but to n  $$ \sum_{k=1}^{n} (k\cdot \ln \frac{2k+1}{2k-1} - 1) =$$ $$ ln \frac{3}{1}\cdot \left(\frac{5}{3}\right)^2 \cdot...\cdot \left(\frac{2n+1}{2n-1}\right)^n - n = ln \frac{1}{1}\cdot \frac{1}{3}\cdot \frac{1}{5}\cdot ... \frac{1}{2n-1} - n $$ but $$ n = ln e^n $$ so it will be $$ln\frac{1}{e^n} \cdot \frac{1}{1}\cdot \frac{1}{3}\cdot \frac{1}{5}\cdot ... \frac{1}{2n-1}$$  So the limit of it is $-\infty$ Have I done this well or I missed sth? New York is a great place to live. New York is a great place to live in.  I've seen the former usage a lot and I've started wondering what the grammar aspects of it are. The main question I'm asking involves the grammar when the preposition in the end of the sentence is deleted. Is it equally formal or correct to omit it? What are the grammar properties of this? Some more examples of similar usage:  This organisation is a great place to work. This is a great place to stay/sit/study/travel/go.  Just to show that 'live' isn't special in this case. Note: I'd posted the same question  before, but the answers were not satisfying enough (the answers there did not seem to provide the precise grammar aspects of this, those that could be in a serious grammar book), so I'm posting this here to get some more views on the question. I hope it is acceptable. How can we get "Developer" bugs logged with Technical Support? I recently found a bug, which I mentioned on , as well as submitting a case, and after a few days fumbling around with the case, they closed it by saying that they only provide this type of support for Premier Support customers.  Is there a better channel for reporting bugs than by submitting a case, or is there something "special" we have to do? I realize this question is similar to , except that I've already gone the route of , as suggested by the answer there (i.e. submitting a case), to no avail.  How can I make sure that a bug like this can find its way to someone capable of at least confirming that the behavior was expected? This behavior isn't documented anywhere, and so I assume that it's a bug that needs to be addressed. Rerender funnel highcharts with new data right now   I have setup /etc/fstab like this:  //192.168.5.167/H /mnt/ssd cifs credentials=/root/.smbreds,noauto,x- systemd.automount 0 0   I want to set it up like first network should be connected and then fstab mount should get mounted. How can I prevent my parents' divorce? I am a young teenager, younger than 16. (I do not want to give my age online)    My dad told me he wants a divorce, but I don't want my parents divorced. My dad says he can't stand my mom anymore.  My dad is older than 45 and my mom is older than 40.    If it happens, I would choose to stay with my mom. My dad can cook and drive, but my mom can't. There's a school bus in high school though.    What can I do to prevent this divorce?

Like I can listen with my old Nokia phone, without using Internet, GPRS etc.  Is iPhone 4 lacking this facility?  I heard about "Pandora Radio" but it uses the Internet to run and it's also not for Indian FM channels.  In my Nokia Express Music Mobile I can listen my local FM stations without any GPRS, Internet in mobile. This user is only displaying 56 rep.   But surely (s)he has much more than that.

I want it to look like:  \sum\limits_{e=1}^{m} but with a capital A (if possible bigger than the normal text) instead of the sum.  Thanks for the help! Why do you need to change your position rather than just focal length to affect perspective? Why must you change your distance from an object to change your perspective of it? Why is it not sufficient to change the focal length of your lens (the zoom level) to change  your perspective? How do I boot into a root shell? When booting to the graphical desktop fails we sometimes are recommended to boot into a "root shell" or to boot in "recovery mode".  How do I do that?
