Generate the answer for a given question. The question requires common knowledge of English. Make sure that the answer is in detail, long, consistent with the context, and requires general knowledge of English. To be less repetitive, please vary your language for each question. Give a proper explanation to answer, and if necessary, provide the definition of various terms. And conclude your answer if it's long. If you have used other resources (e.g., Merriam Webster's.) to answer the question, include citations in your answer. You don't need to paraphrase the context of your resources, but make sure that your answer is consistent and complete.

[EX Q]: I came upon this letter when reading a book, I couldn't find its name on the internet, you can imagine how hard it is to search about it. What is the name of the letter that follows 'sample space'? I know it's not really an English question, but I think this site is best fit for the question than say, the mathematics site.
[EX A]: It's an S written in a fraktur font used by mathematicians. This one is easy to find out using Detexify.

[EX Q]: Is there any difference between the two? In a technical document I have used a phrase 'this is a temporal solution' and my coworker told that he'd use 'temporary' in the context. Is one of the two more correct than the second?.
[EX A]: Temporal means 'pertaining to time'. Personally I have not enountered this word in normal speech at all, even in somewhat formal writing. I have only encountered it as a technical term. For example, in grammar, the part of the sentence that specifies the time at which something happened (e.g. 'today' or 'throughout the year') is a temporal adverbial. The word also comes up a lot in science-fiction wherever some made-up technical term pertaining to time (usually time travel) is required, e.g. temporal mechanics. In real science, the term is sometimes used as a complement to spatial (pertaining to space). Temporary is a much more common word. It means 'lasting for a limited time' and is the opposite of permanent. Politicians sometimes qualify their policies as a 'temporary measure' to give the impression that there are plans for them to be repealed in due course (which, of course, never happens, but that's a different matter). Edit: In the specific example in your question, I think you most likely mean 'a solution that isn't permanent', so temporary is definitely what you need. Temporal is wrong unless you are contrasting your solution against one that is spatial or in some other way not relating to time.

[EX Q]: Exact Duplicate: Can anyone tell me what the suffix '-fu' stands for in the following sentence? I was reading an article on MSDN where I found a mention to google-fu. It says, 'To search for C++ delimeters and code snippets is going to take a little Google-fu on the reader's part.' what does google-fu mean?.
[EX A]:
Google-fu is defined as 'skill in using search engines (especially Google) to quickly find useful information on the Internet.' It is a somewhat tongue-in-cheek reference to kung-fu, which is generally perceived as requiring a high degree of skill to master in the western hemisphere. In the example sentence you provided, the author is suggesting that the expected results are somewhat difficult to attain and you will need to use diligence when searching. I used a bit of Google-fu to research this answer.
