I make it a habit to learn as little as possible by rote, and just derive what I need when I need it. This means my knowledge is already heavily compressed, so if you start plucking out pieces of it at random, it becomes unrecoverable fairly quickly. As near as I can tell, my knowledge rarely vanishes for no good reason, though, so I have not really found this to be a handicap.

I don't think you've understood the article. The idea of the article is that if you're able to derive it, then yes, you can regenerate it. That's what 'regenerate' means.

I think nominul does understand it, and at one level higher than you do. he understands the principle so well he goes and makes a tradeoff in terms of memory used vs execution time.

Take a symetric matrix with a conveniently zero'd out diagonal... you could go and memorize every element on the matrix....(no understanding, pure rote memorization).... you could go and memorize every element AND noticing it happens to be symmetric...(understanding, what you seem to be thinking of...) Or noticing it happens to be symmetric and then only memorizing half the entries in the first place(nominull's approach).

I go with nominull's approach myself...I'm just a lot sloppier about selecting what info to rote memorize.

My experience is that some people have an easier time memorizing by rote than others. Not all brains are wired the same. Personally I learn relations and concepts much easier and quicker than facts. But that may not be the case for everybody. It might not even be advantageous for everybody - at least not in the ancestral environment which had much less easily detectable structure than our well-structured world.
