Ten simple rules for lifelong learning, according to Hamming

In this sequel to our 2007 contribution to the Ten Simple Rules series [2], we attempt to distil the essence of what this mathematician and computer science and telecommunications pioneer addressed in one of his talks [3] and in his book The Art of Doing Science and Engineering: Learning to Learn [4]. [...]when faced with new knowledge, try to establish nodal points in the knowledge network; these will help you to reconstruct the essence of what you have learned even if you can't remember the details.
