Academia folks love to hack on notation. In a research lab I used to work in, my colleagues publishing papers could explain to me the core idea in 2 minutes and probably an undergrad freshman could also understand it. However, if you then read the paper covering the same idea, it would take hours to decipher a fuzzier version of the idea and a freshman undergrad probably wouldn’t bother reading it.
