I recently traveled to a parallel universe where the people wrote in a symbol-heavy language seemingly derived from English. While there, I attended various sorts of collegiate lectures to get a feel for the language; during a particular lecture, I saw this inscription written upon the board:
$$\bbox[13px,border:1px solid black]{(\vee\sqcup):\quad2\text{think}\enspace\wedge\enspace\square=\blacksquare\enspace\wedge\enspace\text{GABA}+\text{crime}}$$
What does it say? What was the lecture about?
