That's how authors of the past compressed and encrypted important knowledge. This is why we've ended up with pearls like "everything is water" and unless you know what "everything" and "water" mean at this level of compression, this is just a funny allegory. Another trick is inventing symbols to compress common concepts, much like the gzip algorithm. Your notes become an Egyptian papyrus to an outsider, but to you they contain all the info without omissions.
