PROBLEM: Question: 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.
Answer: It's an S written in a fraktur font used by mathematicians. This one is easy to find out using Detexify.

SOLUTION: yes

PROBLEM: Question: E.g. is short for exempli gratia, and is in common use to introduce an example within a sentence. Submit a sample of academic writing, e.g., a dissertation chapter. However, some authors use ex. or ex: (short for "example") for the same purpose, and this form is listed in some authorities like the Wiktionary. Submit a sample of academic writing, ex: a dissertation chapter. I know they both roughly mean "example", but which one should I use, and when? Are there connotations associated with one or the other? This question has been asked elsewhere, and this very answer comes up when you ask Google about the difference. It would be good to get an EL&U answer for it.
Answer: "Ex." is not very common, but it may be used to refer to a cited example, eg "See ex. 3". "E.g." is much more common, and is used to introduce an example, or series of examples. In speech, it is usually replaced by "for example".

SOLUTION: no

PROBLEM: Question: The first time I encountered the word "gondola" was as a 20 year old on her first visit to Venice. Gondolas, to me, were written in my memory as a flat, fancy, romantic (and expensive to ride) boat structures that traverse the canals of Venice, Italy. But soon thereafter, on my first visit to Banff, Canada (Canadian Rockies) -- Gondolas was also the term for ski-like lifts (enclosed from the elements) to get from the bottom to the top of steep mountains (vice versa). What is the etymology of "gondola"? And how did it develop to reference two completely different transportation devices? One on water, the other on mountains? What is the relationship besides their obvious transportation connect?
Answer: Some of the successive meanings given in the OED are: 1a. " A light flat-bottomed boat or skiff in use on the Venetian canals, having a cabin amidships and rising to a sharp point at either end; it is usually propelled by one man at the stern with a single oar." U.S. A large flat-bottomed river boat of light build; a lighter; used also as a gun-boat. 4a. "= gondola-car n. U.S.", which is glossed as "U.S. a railway car having a platform body with low sides." 4b. "An elongated car attached to the under side of a dirigible balloon or airship. [German, Dutch gondel.] Also transf., applied to a structure that resembles such a car in its purpose and mode of attachment." 4c. "The car attached to a ski-lift. Also gondola lift." So the crucial step appears to be the cabin of an airship (which is long and low), and then a cabin suspended from something. This kind of semantic drift is very common.

yes
