Learning Mathematical Proofs

If understanding idea requires considering many different ideas in quick succession, it's a lot easier to lose the thread if you have a lower working memory capacity. As you go higher into mathephysics, weaker students naturally drop out. This may seem to put up a barrier to understanding some subjects if you don't have enough raw intelligence. But i actually think the opposite is true, because you can expand your working memory within a subject by creating new uks. Even very complicated ideas are understandable if you've mastered the parts. No subject is too abstract, difficult or confusing that it can't be overcome with patience.
