Having a math degree really was the only reason I solved this one, I'll admit.
The huge amount of single-character words and subscripts used made it likely this was something related to math or physics. For the opening sentence, "In ███████████ ██████ and ██████████, the ███████████ ████████████ is the..." didn't have any words that "physics" would fit into, so I leaned math. There was also this:
How often do you see
that outside of mathematics?
So, maybe a field of mathematics? But which one. There were a ton of ordered pairs (█,█) in addition to that one above. Also a ton of tildes ~. The [█,█) had me interpreting all the ordered pairs as intervals, and that combined with the tildes screamed Probability. Seeing that "In Probability Theory and Statistics" fit in the opening sentence, that really made me feel I was on the right track.
From then, it was a bit of guess work, writing out big Probability vocab words until I found a 12-letter long one. "Distribution" did the trick, but then I was pretty frustrated because 1)There are a bunch of those, and 2)I'll be damned if I can remember all of them! I did guess Distribution then, though, just to make sure I wasn't going down the wrong track.
In the end, I wrote down the names of every Probability Distribution I could think of, and just crossed off every one that wasn't 11 letters long. All that remained from my list were Exponential Distribution and Multinomial Distribution. The presence of so many open intervals had me leaning towards a Continuous distribution, rather than a Discrete one. Seeing there were a lot of "between"s later in the article, that pushed me more towards Exponential. I still wasn't
sure (because, hell, I wasn't great at probability when I was learning it in my 20s, let alone now), but I took my shot with Exponential.
As a math nerd, pretty thrilled to nail the math one.
