1 is not as good as a circle ",which is a common saying of farmers in my hometown. It means to be enlightened, not to be dead. In the present words, you should reduce blindness and jump out of misunderstandings. For example, if you want to make a wooden ball, you can chop it slowly with an axe, but it's best to spin it quickly under the rotary knife, which will be bright and round. "

Because mother Nancy was a teacher in a girls' school at that time, she was an experienced person, and she didn't think her children were "imbeciles", so Nancy taught Edison herself. According to Nancy's usual observation, Edison is not only not an "imbecile", but also often shows his talents. Nancy often lets Edison do experiments by himself. When talking about Galileo's "Leaning Tower of Pisa Experiment", Nancy asked Edison to try it on the tower next to his home. Edison took two balls of different sizes and weights and threw them from the tower at the same time. As a result, two balls landed at the same time. Edison thought it was amazing and told his mother the experimental results excitedly. This experiment was also engraved in Edison's mind.

Some people may think that it doesn't matter what method is used as long as things are done well, but think about it. If you can do something simply and quickly in this way, why use another troublesome method?

Even the effect may be poor, and successful people have a deeper understanding of this. Just like the famous mathematician Gauss, when he was a child, his teacher once gave the whole class a question, from 1 to the sum of 100.

His classmates all added up the numbers item by item on the cursive paper, but Gauss divided them into 50 groups, and the sum of each group was 10 1. It took him only a few minutes to get the answer in this way, which shocked the teachers.

Later, he summed up the formula of the sum of arithmetic progression's first n terms through various studies of calculus, which benefited from his correct method at that time.
