In fact, there is only one sentence:
Feynman's sister became an astronomer according to Feynman's method.
what's the secret? Can we ordinary people use it for our own use?
I think so.
Although there is only one sentence, it contains many rules.
first, the rule of differential product.
as the ancients said, those who accumulate small things are quick.
what is micro is small and fine.
great things in the world must be done in detail. When we study and learn, we must start from scratch, starting with tiny knowledge points, and gradually accumulate.
don't ask for speed, ask for more. Because haste makes waste.
it's a process, or stage, to read from the beginning until you know nothing. This is a pearl of knowledge that you really master.
the second rule is the review rule, or the memory rule.
after mastering the first knowledge pearl in the first step, when learning the next knowledge point, review it from the beginning to see if you really remember and master it. This is the so-called starting from scratch.
the ancients learned new things by reviewing the old ones. Most people like the new and hate the old. They are only happy to know the new and don't like to review the old knowledge. Actually, this is a big pit. Because according to Ebbinghaus's forgetting rule, you will forget 42% if you don't review something new for 2 minutes. Learning the new without reviewing the old knowledge is no different from breaking corn with a blind bear.
the third rule is the exponential rule. The books we read, the knowledge we learn is not single, but network. The pearls mastered by the previous knowledge will form a network of links with the later knowledge. After a pearl we grasp forms a network, 1, online pearl strings will be formed. The more we master, the easier it is to understand and master the later knowledge. I understand the little knowledge points in front, try to read down and open new little pearls, so it goes back and forth step by step. A book can be grasped.
