Lightning Calculation (also called lightning mental arithmetic) is from The Complete Secret Works (translated by Carrel and Wang Yang). ), talking about a gift in the subconscious. "The subconscious mind guides all the key processes of our body. You don't consciously breathe. You don't need to judge, decide and command every breath. The subconscious mind is responsible for these activities. When you are reading this text, you don't have to consciously consider that you are breathing. The same is true of the relationship between thoughts and your blood circulation. Just like the muscle in your arm, the heart is also a muscle. It can't move or guide its own behavior. Only thoughts, only things that can think, can guide our muscles, including the heart. You didn't consciously control your heartbeat. The subconscious is doing this work, and it is also responsible for the digestion of food and its own construction and repair. In fact, all key processes are handled by subconscious thoughts. " "Lightning calculation" is an "intuition" provided by the subconscious mind. Consider the example of "blind" Tom. Maybe you've heard of him. You know he can repeat a tune on the piano as soon as he hears it for the first time. People call it abnormal. In fact, subconsciously, he is much more normal than all of us, but we are not normal because we can't do that. "Lightning calculator", in the calculation process, as long as numbers and arithmetic rules are given, he can know the answer instantly without deviation. The operation speed is like lightning, so it is called lightning operation or lightning mental arithmetic. He may only be a boy of seven or eight years old, but if you ask him what 7649.437 divided by 326.2568 is, he may have given the answer before you finished writing these two numbers. You may think he is unusual. But you should be able to do it yourself. Your subconscious has this ability. Dr Hudson listed many examples of this kind of genius in his book The Laws of Physical Phenomena. Here are just a few simple introductions: "For mathematical geniuses, their scores in calculation, including speed and accuracy, far exceed those of well-educated mathematicians. These geniuses did these amazing things when they were only 3- 10 years old. These children themselves don't know how to finish these calculations. Later, two became prominent figures, and many of them did not perform well in objective intelligence. " Whitley described his talent as follows: "There must be something special about my computing ability. I began to show it when I was five or six years old, and it lasted for about three years. I can get the answer to the most difficult arithmetic problem quickly. They have always existed in my mind, and I know nothing about numbers except arithmetic. I do these arithmetic problems faster than anyone who can work them out on paper, and I never remember making any mistakes. After I went to school, this passion disappeared, and I became a fool of calculation. Since then, it has been like this. " "Dr. Safford became an astronaut. 10 years old, he accurately calculated a multiplication problem with an answer of 36 digits. In the later childbirth, he never showed such an amazing move. " Benjamin Hall Bryan asked his father when he was 6 years old. Father told him that it was 4 o'clock. After looking at the time on his watch, he told his father how many seconds he had lived. His father calculated and said to Benjamin,' You have miscalculated, it should be 172000 seconds.' The child replied, "Oh, Dad, you forgot to count 1820 and 1824." That's what happened. ""Then Dr. Scofield wrote a story about Zillah Colborn: Qi Lacorre Bourne can say that the square root of 106929 is 327, and the cube root of 268336 125 is 645. Before the question of how many minutes is 48 years, he can type 252888 10 minutes. He can immediately give two factors of 247483, namely 94 1 and 263, and only these two factors; When asked about the factor of 36083, the answer is no-this is a prime number. He can't describe how the answer got into his mind. He can't do simple multiplication and division on paper. "Berthelot, the great French founder of modern chemistry, once said in a letter to a close friend that the experiment that led to his ultimate great discovery was not the product of a series of closely related and closely reasoned ideas. On the contrary, "they can be said to have come from themselves and fallen from the world." Charles M Barrow said in his book Suggesting Substituting Drugs: "If a person is asleep, he needs power beyond his daily consciousness. Many people acquire knowledge not through ordinary perception, but through direct communication with another conscious agent, who seems to know their happiness better than their daily guesses. I know some people, like me, can know the general idea of a letter without opening it. A few years ago, a friend of mine came to Boston for the first time and arrived at Providence Railway Station in Garden Square. He is going to Lowell station on the other side of the city. As he was completely unfamiliar with the street and didn't know the general direction, he went straight ahead without asking for directions and reached his destination by the shortest route. In doing so, he relies entirely on what he calls an "intuitive guide", rather than getting hints or clues through his senses. According to scientists, geniuses in the fields of literature, art, business, government, politics and invention are all ordinary people like you and me, but they have learned how to use their subconscious. It is said that Sir Newton's excellent knowledge of mathematics and physics was not obtained through conscious efforts, and Mozart described his wonderful melody as "coming to him by himself". Descartes had no formal education at all. The result is that, as H*G* Wells described in his book Man as God, there is no need for schools and teachers to exist except to tell us how to understand the infinite knowledge of subconscious thoughts that we have since we were babies.
