Why take notes?

Found in [@ahrens2017, 12]:

“Notes on paper, or on a computer screen […] do not make contemporary physics or other kinds of intellectual endeavor easier, they make it possible … no matter how internal processes are implemented […you..] need to understand the extent to which the mind is reliant upon external scaffolding.” [@levy2011]

And, again the OG of the Zettelkasten method:

“One cannot think without writing.” [@luhmann1981]
