On September 29th, 2009 (August 11th, 2009 in the lunar calendar), Shi Fengshou, a master of quick calculation, passed away. Graduated from the Department of Mathematics of the University of Science and Technology of China in 1980, and served as the director of the International Research and Training Center of Shi Fengshou Speed Algorithm and the director of Shi Fengshou Speed Algorithm Research Institute. Professor Shi Fengshou, a member of the 8th and 9th National Committee of the Chinese People's Political Consultative Conference, a member of the Chang Shi Fengshou Committee of the All-China Youth Federation, a member of the Central Committee of the Revolutionary Committee of the Chinese Kuomintang, and an inventor of international quick calculation, began to study the quick calculation algorithm at the age of 11. After 10 years' efforts, he successfully broke the traditional calculation method of four arithmetic operations for thousands of years, and created a quick calculation method that can calculate from a high position and give the correct answer. Professor Shi Fengshou has not only attracted the attention of international academic circles, but also been listed as a mathematical genius in Chinese mainland. The calculation speed of Shi Fengshou's algorithm is even faster than that of a calculator. It was officially named by the state in 1990, and now it has been compiled into the textbook of Modern Primary School Mathematics, a nine-year compulsory education in Chinese mainland, and the formal national textbook in Malaysia. Professor Shi Fengshou's deeds have been compiled into Chinese textbooks, ideological and moral textbooks and politics textbooks in middle schools in Chinese mainland. UNESCO praised the "Historical Harvest Speed Algorithm" as a miracle in the history of educational science, which is of great significance to the development of human brain intelligence and should be promoted all over the world. In May, 1991, the Shi Fengshou International Research and Training Center for Speed Algorithms was established in Shenzhen, China. Chinese-American and world-famous mathematician Professor Chen Shengshen and Nobel Prize winner Professor Yang Zhenning also wrote congratulatory inscriptions respectively. Mayor, Director-General of UNESCO, personally sent a congratulatory letter. The "Shi Fengshou Speed Algorithm Research Institute" was subsequently established, becoming an important academic center for studying the "Shi Fengshou Speed Algorithm". Chronicle of Shi Fengshou's Harvest Speed Algorithm In 1968, the outward shift method was used to solve the multi-digit multiplication problem. In 1969, we successively conquered the fortress of quick calculation of addition, subtraction, multiplication and division. In 1970, three teachers, including lecturer Ma Jialu of Northwest University, helped Shi Fengshou summarize and sort out, and printed 40 copies of mimeographed materials of Shi Fengshou Speed Algorithm, marking the advent of Shi Fengshou Speed Algorithm. In September, 1971, the Provincial Department of Education recommended Shi Fengshou to study in the High School attached to Northwest University. In 1972, he was invited by Professor Zhao Cigeng of Beijing Normal University to Beijing, and successively performed quick calculation performances in Beijing Normal University, Institute of Mathematics, Chinese Academy of Sciences, and Peking University, which was enthusiastically supported by scientists such as Wu Youxun and Hua Luogeng. Shi Fengshou graduated from high school in 1975, and the Provincial Department of Education recommended him to go to Peking University. He was returned because he had no experience of "going to the countryside". In 1976, Shi Fengshou returned to his hometown to farm, and later became a private teacher. In February, 1978, with the instructions of Vice Premier Fang Yi of the State Council, the University of Science and Technology of China made an exception to admit Shi Fengshou to the Department of Mathematics for further study. In March 1979, Shi Fengshou's book "Fast Calculation Method" was officially published. In September of the same year, CCTV held a TV lecture on Shi Fengshou's speed algorithm, which was broadcast continuously for more than 20 days, and the speed algorithm spread all over the country. In September 1984, Shi Fengshou became the director of China Institute of Speed Algorithms. On October 16, 1990, with the support of relevant state departments, the naming ceremony of "Shi Fengshou Speed Algorithm" was held at Diaoyutai State Guesthouse in Beijing, which was the first named natural science achievement in China. In April and May, 1991, the "International Research and Training Center for Shi Fengshou Speed Algorithm" was established in Shenzhen. In the same year, the State Education Commission officially incorporated the historical harvest speed algorithm into the computing technology textbooks of secondary vocational and technical schools across the country. On October 1, 1992, in recognition of Shi Fengshou's outstanding contribution to the development of China's scientific and technological undertakings, the State Council decided to issue special government allowances and certificates from October 1992. In December, 1997, Shi Fengshou's speed algorithm was compiled into the fourth, sixth, seventh and eighth volumes of Modern Primary School Mathematics textbook. Extended reading: The legendary life of Shi Fengshou, a master of quick calculation. Extended reading: The legendary life of Shi Fengshou, a master of quick calculation. Through Shi Fengyou's oral narration, the legendary life track of Professor Shi Fengshou, an international master of quick calculation, is presented to reporters. 10-year-old baby subverts the Millennium calculation method On February 23, 1956, Shi Fengshou was born in an ordinary farmer's family in Liangyi Town, Dali County, Weinan. When I was in the second grade of primary school, one day in arithmetic class, Shi Fengshou asked the teacher a strange question: "Can arithmetic be counted from left to right and from high to low?" At this moment, the teacher didn't criticize him for asking strangely, but encouraged him to say, "Thousands of years have been counted from low positions at all times, at home and abroad. This is the experience summed up by the ancients. If you have the ability, you can invent and create!" As a result, Shi Fengshou, who was only 10 years old, really started to invent and create. Since then, he has been lying on the big kang at home every day to list formulas and find rules. When the exercise book is finished, write it on waste paper; When the waste paper is finished, draw it on yourself; If you can't paint on your body, just paint on the ground and wall. Shi Fengyou, a younger brother, recalled that at that time, the walls of the home were full of formulas written by his brother, and the snow-white walls became "pockmark faces". At that time, the whole home became a sea of numbers. Once my mother gave my brother two big buns to eat, but I didn't expect my brother to write dense numbers on the big buns. In this way, after seven months of calculation, my brother finally figured out the quick calculation rule of multiplying any number by 2 to 9, from left to right, from high to low, and compiled the quick calculation formula of "calculating the front position, looking at the back position, and carrying in advance". Why should we promote the speed algorithm? In 1980, after Shi Fengshou graduated from the Department of Mathematics of University of Science and Technology of China, he has been devoted to the promotion of speed algorithms. "Shi Fengshou International Research and Training Center for Speed Algorithms" and "Shi Fengshou Research Institute for Speed Algorithms" have been formally established in Shenzhen, and gradually set up training center branches all over the world. In the era of prevalence of electronic computers, what is the significance of learning and popularizing historical harvest speed algorithm? Shi Fengyou, the younger brother of Shi Fengshou, answered the reporter. Mr. Mbo, Director-General of UNESCO, once said that the side effect of long-term dependence on computer calculation is the gradual degradation of human thinking ability, which is a disastrous consequence for all mankind. Shi Fengshou's quick calculation method can avoid the negative effects of over-reliance on advanced scientific and technological tools. Famous scholars toffler, Yang Zhenning, Chen Shengshen, etc. all pointed out that learning to master the historical harvest speed algorithm and improving the calculation speed is only one aspect, and more importantly, it can promote the development of people's thinking to a higher level. If the historical harvest speed algorithm is combined with the electronic computer and its hardware is modified, the calculation speed of the electronic computer will be further improved. This is an extremely meaningful research topic to be discovered. Shi Fengshou's fast algorithm, which uses the extension and flexion of five fingers of the left hand and combines the brain for rapid calculation, has been affirmed by international psychology and brain science experts as the best way to exercise the right brain of human beings, and has been included in contemporary intelligent engineering. After the "quick calculation prodigy" met professor Hua Luogeng Shi Fengshou "invented" the quick calculation law of multiplying any number by 2 to 9, from left to right, and from high to low, it attracted people's attention and became more obsessed with the research of speed algorithm. Once he was walking in the street with a friend, he muttered numbers in his mouth and kept pinching his fingers. Shi Fengshou didn't hear these words at all, and was still immersed in his own digital world. After his companion told him, he couldn't help laughing: "Ah, I'm a psycho!" Shi Fengshou calculated like this for three years, and finally, on the basis of solving one-digit multiplication, he figured out a set of quick calculation rules for multi-digit multiplication and addition, subtraction and division. In 1972, recommended by Professor Liu Zhihe of Northwest University, Professor Zhao Cigeng of Beijing Normal University took this "child prodigy" to perform a quick calculation performance in Beijing, which caused a sensation. The most striking thing is the "competition" between Shi Fengshou and Hua Luogeng, a famous Chinese mathematics professor. Hua Lao took an abacus, and Xiao Shi used quick calculation. As a result, Xiao Shi defeated Hua Lao! Hua Luogeng said happily, "You are one lap faster than others now. I hope you can use your speed algorithm on electronic computers in the future and improve it by another lap." Shi Fengshou Speed Algorithm is famous all over the world. Shi Fengshou Speed Algorithm has attracted worldwide attention. In August, 1987, UNESCO Director-General Mbo visited China, specially met with Professor Shi Fengshou, watched his quick calculation performance, and was amazed. He immediately invited Shi Fengshou to attend the 24th UNESCO General Conference. At noon on October 23, 1987, at the UNESCO Building, Shi Fengshou performed a quick calculation performance for the representatives of 158 Member States attending the conference. The first question was asked by the wife of Sri Lanka's representative to UNESCO. When the wife wrote 891876 times 9 on the blackboard, and the chalk in her hand had not been put down, Shi Fengshou had already written the answer: 8026884. Subsequently, the calculator in the referee's hand also showed the same answer. During the performance of more than half an hour, Shi Fengshou performed multi-digit mathematical operations such as addition, subtraction, multiplication, division and square, and introduced the principle and popularization of quick calculation to the audience, which won bursts of applause. The Indonesian ambassador, who served as the referee, held the hand of the young quick calculation expert and said humorously, "My conclusion is that your brain is faster than a computer!" Malaysia's third TV station called Shi Feng's quick calculation algorithm another great invention of the world after gravity. In December, 2004, Koichiro Matsuura, Director-General of UNESCO, met with Shi Fengshou at the headquarters of the organization in Paris, thanked him for his "active support for human education" and encouraged the global popularization of Shi Fengshou's speed algorithm. The first case is named: "Shi Fengshou Speed Algorithm" Shi Fengshou Speed Algorithm attracted the attention of Shaanxi Provincial Department of Education, and he was sent to the High School attached to Northwest University by the Provincial Department of Education. After graduating from high school, in view of his excellent grades, the Provincial Department of Education recommended him to go to Peking University, but this application was not approved because he didn't "go to the countryside". In 1977, the college entrance examination was resumed, and Shi Fengshou happily participated in it, but he failed due to insufficient preparation and suffered another setback. In January, 1978, Shi Fengshou decided to volunteer himself in Beijing, and set foot on the train to Beijing on the fourth day of the Lunar New Year. His speed algorithm has also been affirmed by relevant experts and scholars of the Chinese Academy of Sciences. With the instructions of Fang Yi, Vice Premier of the State Council and President of the Chinese Academy of Sciences, the University of Science and Technology of China made an exceptional admission to Shi Fengshou as a mathematics student. In March, 1979, with the support and help of the school, Shi Fengshou wrote and published his first monograph "Fast Calculation Method", which published more than 20 million copies successively. In September of the same year, CCTV specially invited him to hold a TV lecture on "Fast Calculation Method", which caused a sensation in the whole country. Shi Fengshou immediately became famous and became an idol worshipped by teenagers all over the country. On February 21, 1989, 10 well-known mathematicians, Cheng Minde, Ding Shisun, Jiang Zehan, Duan Xuefu, Zhuang Qitai, Zhao Cigeng, Sun Shuben, Sun Yongsheng, Yan Shijian and Liu Shaoxue, jointly wrote a letter to Premier Li Peng, asking the state to give "legal protection" to Shi Fengshou's speed algorithm. After receiving this letter, Premier Li Peng instructed that "the country should protect the achievements of Shi Fengshou". Comrade Song Jian specially met with Shi Fengshou, and the State Science and Technology Commission issued a document to protect Shi Fengshou's inventions. Later, the relevant state departments officially named the "Historical Harvest Speed Algorithm", which became the first official name of a natural science invention by the state.
