Mathematical Rigor out of Byzantine Ways
According to Khan Academy's wonderful video tutorials on Linear Algebra:
"If anything, in linear algebra, the gods of linear algebra are kind of experts in to some degree stating simple and obvious things in convoluted and Byzantine ways, but it does that for a reason: it gives it 'mathematical rigor'."
I'll remember that as a handy euphemism for when people ask how any research paper on a seemingly simple topic can be converted into a voluminous tome.
