Viewing computer screen through 3D glasses, why the asymmetry? I have 3D glasses made up of plastic.  First case: When I hold front side of the 3D glasses (by this I mean that side on which light falls) in front of a computer screen, light coming from screen is not blocked, at any angle of rotation. But I see somewhat (slightly) bluish screen when 3D glasses are held horizontally; and yellowish (slightly) screen when glasses are held vertically.  Second case: Now I flip the side of the glasses i.e. "back" side of glasses is in front of screen and "front" side is closer to eyes. In this second case, when glasses are held horizontally, the light is blocked. When glasses are held vertically, light is not blocked; I can see the screen. For intermediate angle, intensity of light varies from minimum to maximum.  Questions:   Why I get slightly colored screens in the first case and why light is not blocked ? Why light is blocked in the second case ?   I know (after reading somewhere) that glasses consists of a pair of circular polarizer and linear polarizer. Circular polarizer in my first case will be near to computer screen and linear polarizer will be near to eyes; and in second case vice versa. How do you make a deep copy of an object?

Let $a_k:=(-1)^k$ where $k\in\mathbb{N}$. $\mathbb{N}$ is the set of all non-negative integer.  And we define the partial sum $S_n:=\sum \limits_{k=0}^{n}a_k$. Notice that the sequence $\{S_k\}$ diverges which also implies that the infinite series $\sum \limits_{k=0}^{\infty}a_k$ cannot be defined.  If I consider the infinite sum $1-1+1-1+1-1+\cdots$, then this statement is equivalent that I just defined the infinite series $\sum \limits_{k=0}^{\infty}a_k$, which is contradiction.  But, suppose that the sum $1-1+1-1+1-1+\cdots$ exists and let the value of the sum be $S$. Then, we can easily observe that $S=1-S$, therefore $S=1/2$. The supposition of this proposition already proved as false, but if I ignore the definition of infinite series, it holds.  Which one is right? Or are these propositions depends on what we define?

So, I decided that a previous project contained exactly what I needed to expedite a new project, so I appended the appropriate objects form the previous project to the new one. This was great, because I didn't have to define new materials, &amp;c.   Regrettably, though, I found out that when it came to vertex groups, where it would have been as helpful to be able to copy vertex groups from one object to another as it was to copy materials, I couldn't figure out how to do so.   Am I looking for a feature which does not yet exist?  NOTE: I did not expect the vertex groups to have assignments in the target objects, but it would have been handy not to have had to retype 25 names. A question in four parts.   What are the main problems which supersymmetry purports to solve?  What would constitute lack of evidence for SUSY at the proposed LHC energy scales (e.g. certain predicted superpartners are not in fact observed)?  Are there alternative theoretical approaches which would address the SUSY problem set and which would still be credible in such an LHC no-SUSY-scenario? Where would LHC-disconfirmation of SUSY leave String Theory?   I would like to think that these four points could be taken together as one question.

I want to know if the latest version of Openlayers (v4.0.1) supports Google Maps as a Tile Layer. I can't find any document ion about this. If Openlayers doesn't support Google Maps, could someone  tell me if there is any way to do this? This is a question you can read everywhere on the web with various answers:  $ext = end(explode('.', $filename)); $ext = substr(strrchr($filename, '.'), 1); $ext = substr($filename, strrpos($filename, '.') + 1); $ext = preg_replace('/^.*\.([^.]+)$/D', '$1', $filename);  $exts = split("[/\\.]", $filename); $n    = count($exts)-1; $ext  = $exts[$n];   etc.  However, there is always "the best way" and it should be on Stack Overflow. How do I set up a global locale for the computer?  I have recently installed Kubuntu 14.04LTS in english but since I am in Spain, I chose Spain as a country and then changed locale options so that I get all country specific configuration such as digit grouping, decimal separator, date format, etc. I also added the spanish language.  Now all applications complain that locale is wrong. check-language-support tells me I'm using en_ES.UTF-8 as system's locale, and that locale is indeed wrong, there is no locale for english language in Spain.  I tried using Kubuntu's country/region &amp; language settings but it doesn't fix it. I tried using export LANG=en_GB.UTF-8 and export LC_ALL=en_GB.UTF-8 and then sudo dpkg-reconfigure locales and that caused check-language-support to say that I now have a correct configuration but if it is, it's only in that konsole session. This problem also prevents konsole from showing unicode characters and I cannot use dead keys or enter any 'international character' such as ñ or ç (those work on other applications such as Firefox, that I'm using to post this question).  So the question is: How do I set up a global locale for the computer?  This is not a bug report, I will probably reinstall my computer eventually if I can't fix it. But I really want to know how I can perform this REALLY basic task.  Thank you.  $ check-language-support perl: warning: Setting locale failed. perl: warning: Please check that your locale settings:         LANGUAGE = "en:es:en",         LC_ALL = (unset),         LC_PAPER = "en_ES.UTF-8",         LC_ADDRESS = "en_ES.UTF-8",         LC_MONETARY = "en_ES.UTF-8",         LC_NUMERIC = "en_ES.UTF-8",         LC_TELEPHONE = "en_ES.UTF-8",         LC_IDENTIFICATION = "en_ES.UTF-8",         LC_MEASUREMENT = "en_ES.UTF-8",         LC_TIME = "en_ES.UTF-8",         LC_NAME = "en_ES.UTF-8",         LANG = "en_ES.UTF-8"     are supported and installed on your system. perl: warning: Falling back to the standard locale ("C"). locale: Cannot set LC_CTYPE to default locale: No such file or directory locale: Cannot set LC_MESSAGES to default locale: No such file or directory locale: Cannot set LC_COLLATE to default locale: No such file or directory hunspell-en-ca libreoffice-help-en-gb libreoffice-l10n-en-gb libreoffice-l10n-en-za mythes-en-au wspanish  $ cat /etc/default/locale LANG="en_US.UTF-8" LC_NUMERIC="es_ES.UTF-8" LC_TIME="es_ES.UTF-8" LC_MONETARY="es_ES.UTF-8" LC_PAPER="es_ES.UTF-8" LC_NAME="es_ES.UTF-8" LC_ADDRESS="es_ES.UTF-8" LC_TELEPHONE="es_ES.UTF-8" LC_MEASUREMENT="es_ES.UTF-8" LC_IDENTIFICATION="es_ES.UTF-8"   $ locale locale: Cannot set LC_CTYPE to default locale: No such file or directory locale: Cannot set LC_MESSAGES to default locale: No such file or directory locale: Cannot set LC_ALL to default locale: No such file or directory LANG=en_ES.UTF-8 LANGUAGE=en:es:en LC_CTYPE="en_ES.UTF-8" LC_NUMERIC=en_ES.UTF-8 LC_TIME=en_ES.UTF-8 LC_COLLATE="en_ES.UTF-8" LC_MONETARY=en_ES.UTF-8 LC_MESSAGES="en_ES.UTF-8" LC_PAPER=en_ES.UTF-8 LC_NAME=en_ES.UTF-8 LC_ADDRESS=en_ES.UTF-8 LC_TELEPHONE=en_ES.UTF-8 LC_MEASUREMENT=en_ES.UTF-8 LC_IDENTIFICATION=en_ES.UTF-8 LC_ALL= $ update-locale perl: warning: Setting locale failed. perl: warning: Please check that your locale settings:         LANGUAGE = "en:es:en",         LC_ALL = (unset),         LC_PAPER = "en_ES.UTF-8",         LC_ADDRESS = "en_ES.UTF-8",         LC_MONETARY = "en_ES.UTF-8",         LC_NUMERIC = "en_ES.UTF-8",         LC_TELEPHONE = "en_ES.UTF-8",         LC_IDENTIFICATION = "en_ES.UTF-8",         LC_MEASUREMENT = "en_ES.UTF-8",         LC_TIME = "en_ES.UTF-8",         LC_NAME = "en_ES.UTF-8",         LANG = "en_ES.UTF-8"     are supported and installed on your system. perl: warning: Falling back to the standard locale ("C"). 6-letter permutations in MISSISSIPPI How many 6-letter permutations can be formed using only the letters of the word, MISSISSIPPI? I understand the trivial case where there are no repeating letters in the word (for arranging smaller words) but I stumble when this isn't satisfied. I'm wondering if there's a simpler way to computing all the possible permutations, as an alternative to manually calculating all the possible 6-letter combinations and summing the corresponding permutations of each. In addition, is there a method to generalize the result based on any P number of letters in a set with repeating letters, to calculate the number of n-letter permutations?  Sorry if this question (or similar) has been asked before, but if it has, please link me to the relevant page. I also apologize if the explanation is unclear, or if I've incorrectly used any terminology (I'm only a high-school student.) If so, please comment. :-) It seems like I'm doing something wrong when using foreach variables to indicate node numbers. The two foreach loops are anchoring the paths to the east of each node.
