So far I'm considering Pre-Calc, Microbiology, Chemistry, Organic Chemistry, and Physics.
Clearly many of the posters here have never heard of knowledge for its own sake. What a pity but, I suppose, a sign of the times.
There is a saying to the effect that wine is made by farmers while beer is made by engineers. I'm not sure that really applies broadly to home brewers but certainly it applies to some especially those who have to know how things work, those that like to experiment and those whose enjoyment of the hobby involves making bits of their own gear including programming controllers.
In trying to think of the answer to the question 'what disciplines with which I have some familiarity have I used in brewing in one way or another' the best answer I can come up with is 'most of them'. That makes it tough to give you a short list.
In looking at your list certainly basic math, which is, I assume, things like graphs, analytic geometry, trigonometry, sets, limits and stuff like that, is essential. Calculus itself, at least differential calculus, comes up quite a lot but I haven't had to evaluate many integrals in brewing (and when I have I just used the computer). Basic chemistry is a must and to that I would add biochemistry. I'd skip the organic. Isn't it the basis of biochemistry? Sure but when a sugar molecule goes from the ladder form to the ring form all you need to know is that a hemiacetyl is formed - not where all the damned electrons went.
The subset of chemistry I probably spend most time on is p-chem (physical chemistry). Wort and beer are dilute solutions and understanding chemical equilibrium is essential to understanding things like water chemistry, how the density of worts and beers change with sugar and alcohol content, evaporation rates in the kettle, beer color, pH and how to measure it... Certainly microbiology should be on the list. Physics- hmm. It is true that anyone interested in any of the sciences should be versed in basic physics as it is ultimately at the heart of everything else discussed here. As you really can't teach it without introducing some calculus that may be the way to pick up some of that (don't take a 'Physics for Poets' class).
