through 「 Today in history 」, Look at the future from the past , You can change the future from now on .

It's today 2022 year 6 month 19 Japan , stay 1997 Years of today , Developed by Computer Research Institute of National University of defense technology “ The Milky Way -III” Ten billion times supercomputer system , It has passed the national technical appraisal in Beijing . The comprehensive technology of this system has reached the current international advanced level , And has broken through and mastered the key technologies of higher-level computers , It has the ability to develop higher performance supercomputers , It marks a new breakthrough in the development technology of high-performance supercomputers in China . Only a few developed countries in the world have mastered the development technology of high-performance supercomputers .“ The Milky Way -III” The successful development of the supercomputer , This has enabled China to step into the world's advanced ranks in this field .

1623 year 6 month 19 Japan ： Mechanical calculator pioneer Blaise Pascal born

Blitz ‧ Pascal （Blaise Pascal） Born in 1623 year 6 month 19 Japan , He is a French theologian 、 philosopher 、 Mathematician 、 physical scientist 、 chemist 、 musician 、 educators 、 Meteorologist . Pascal's early research in natural and Applied Sciences , He has made important contributions to the manufacture of mechanical calculators and the study of fluids , Extending Torricelli's work , The concepts of pressure and vacuum are clarified . Pascal also vigorously defended the scientific method . The math , Pascal contributed to two important new areas of research . He 16 At the age of, he wrote a paper entitled projective geometry ,1654 Started with Pierre · Virtue · Fermat communications , Discuss probability theory , It has profoundly influenced the development of modern economics and social sciences .

Pascal has shown amazing talent in mathematics and science since he was young . In his 11 At the age of , He wrote a paper on the sound of body vibration , His father is in his son 15 He was forbidden to pursue mathematical knowledge before the age of , Lest he neglect the study of Latin and Greek . But one day , Pascal's father found that Pascal was writing an independent certificate on the wall with a piece of charcoal , That is, the sum of the angles of the triangle will be equal to the sum of the two right angles 180 degree . From then on , Pascal was allowed to study Euclidean geometry , And attend some outstanding mathematicians and scientists in Europe in the monastery , For example, robeval 、 Gillard · Deshag 、 Medog 、 Gassendi , And Descartes .

1642 year , To alleviate his father's endless 、 Repeatedly calculate the tax revenue and expenditure burden , under 19 Pascal, aged, worked hard to build a calculator that could run addition and subtraction , Called Pascal calculator . And in the Musee des Arts and crafts in Paris and the Musee Zwinger in Dresden, Germany , Showing his original two calculators . Although these machines later became pioneers of early computer engineering , But at that time, it did not cause great commercial success . Because it is too expensive , So that it becomes more like a toy , Finally, it became the symbol of French and even European nobles to show their status . However, Pascal will continue to refine his design in the next decade , And a total of 20 A machine like this .

Pascal's life has influenced mathematical research . He was in 1653 Year of 《 On arithmetic triangle 》 A tabular representation of binomial coefficients is described in , Each number in the table is equal to the sum of the two numbers on its shoulder , It is now called Pascal triangle . stay 1654 year , Under the influence of a friend who is keen on gambling , Pascal and Fermat communication discussion , And hence the birth of mathematical theory ： probability theory . This friend's specific problem is ： Based on the probability of winning the bet , How do two players who end the game ahead of time score the bet fairly given the current bet . The concept of expectation was put forward in this discussion . The analysis and probability work completed by Fermat and Pascal laid the foundation for Leibniz to propose infinitesimal calculus .1654 Years later, he was influenced by religious experience , Pascal almost gave up his math job .

stay 1654 After a mysterious religious experience at the end of the year , He left the fields of mathematics and physics , Focus on meditation and theological and philosophical writing . He was a staunch Janssen all his life , The humanistic thought was greatly influenced by Montaigne . A work of religious debate 《 Letter to people from other provinces 》（Lettres provinciales） It is regarded as a model of French writing , Its notebook is compiled as 《 Thought record 》.1662 year , Pascal's condition worsened , The emotional state has also deteriorated a lot due to the death of my sister a few years ago .
