I was thinking the other day about "all Greek to me!" as I was reading a physics book w/equations (using the Greek symbols)
And equations are a sort of language, of course.
So I wondered if there's some sort of linguist who's ever looked at the grammar or syntax of math/physics equations and tried to derive, whatever the hell it is linguists derive!
Does this sound like something anyone has heard of? If so, have any links?

Here's an obnoxious school question that's been nagging me for days:
Suppose that the height (at the shoulder) of adult African bull bush elephants is normally distributed with µ = 3.3 meters and ∂ = .2 meter. The elephant on display at the Smithsonian Institute has a height 4 meters and is the largest elephant on record. What is the probability that an adult African bull bush elephant has height 4 meters or more? [more inside]

Back in middle school and high school we'd play these fun math games where you'd have to draw a chart and figure out who had what. Example, there are five people, joe jon julie mike and amy. Each has a favorite color. Mike doesn't like red, but amy doesn't like blue, etc etc. What are these called and where can I get more? They were a blast!!

I am looking for a math typesetting style guide. By this I don't mean the kind of stylesheet for journal submissions that says "Be sure to use the blah-blah-blah LaTeX package and the XYZ equation environment, and our army of editorial assistants will tie up the loose ends and knock off the rough edges." (Why not? Because my advisor is involved in starting a new journal, and suddenly my labmates and I
are that army of editorial assistants.)

InterviewPrepFilter: I need to brush up on my numerical reasoning. I'm looking for ways to master things like word/story problems (probability, work-rate, distance), and some math review. I have good logic skills, but basic math can be confusing for me, esp. under pressure. Tutoring is not really an option and anything that is cram-friendly is also good. Any books, resources, tips, general guidance from math-y people ?

I measured the number of people who had trait X (or did not have trait X) in two locations, A and B. Now, I want to test the statistical significance of these results. Is the chi-square test sufficient for this? Or is there a better option?
