In the past few days, the counterattack of the epidemic has made us feel the charm of big data again, such as through the base station, we can accurately know how many people appear in this place in a time period, and then the color of their health code will change from green code to yellow code, and then check them one by one to find out whether these people will have a security impact.
The child did not know how to ask us, what is big data, this is interesting, because we do not know, just received the "Smart Brief History" picture book, so began to find the answer journey.
To talk about big data, we have to talk about the origin of the number!
People living in Shang Zhou, if you ask him how many cattle he has in his house, he will only show it by extending his finger or giving you a knot, and if there is a general on the battlefield at that time, it will definitely kill the general, and in order to cope with this situation, people invented a calculation. Counting is to use some small sticks with the same length and uniform thickness, through the vertical and horizontal two placement methods to represent the number 1--9, but the problem comes again, the calculation chip is not fully popularized, and it is also very slow, at this time, smart people invented the abacus. The abacus began in the Han Dynasty, 4,000 years ago, in this open mobile phone calculator can come up with the answer today, there are still many industries, many people use the abacus, and, also known as the predecessor of the "modern computer".
However, with the rapid development of society, there are more and more problems that the abacus cannot solve, so smart people combine the experience of their predecessors and invent new things to deal with.
In December 2020, the "nine chapters" quantum computing prototype developed by China was born! It was named "Nine Chapters" for a few years, the famous Chinese mathematical monograph "Nine Chapters of Arithmetic", the speed of calculation is one hundred billion times faster than the current strongest electronic computer, and what stages have gone through, and which new inventions have emerged, and who invented these inventions? It is found in A Brief History of Cleverness: Computational Thinking in History (hereinafter the same as "A Brief History of Cleverness").
"A Brief History of Intelligence" is edited by Ape Programming, selecting 14 problems encountered in the history of human computer thinking, and using more than 100 exquisite illustrations in the book to introduce 20 inventions and the stories of 26 scientists and inventors, showing human wisdom and perseverance in overcoming difficulties.
The book "A Brief History of Intelligence" is simply informative and very interesting, very suitable for children interested in computers or programming to make a popular science picture book for computational thinking, and has also been jointly recommended by Wang Zhigeng, director of the Capital Library, and Wu Jun, a computer scientist and winner of the Wenjin Book Award. Of course, this picture book not only attracts children, but also attracts me, our baby is relatively young, but the picture book matching the sticker music is very happy.
Each invention in "A Brief History of Cleverness" is introduced through four parts: problems, clever solutions, smart people, and knowledge expansion. Through these four parts, we can know why this invention existed, what problems this invention solved, who invented it, and how this invention was used in real life.
For example, in the invention of the abacus, although the small abacus is simple, how to use it? How to let more people use it? ...... The Ming Dynasty abacus operator Cheng Dawei perfected the abacus recipe, from which abacus up to the officials down to the people, have been applied to practical life, in the expansion of knowledge, let us know that in addition to China and other countries also have abacus, and after a long time, this abacus can not meet people's needs, new inventions are about to appear.
In "A Brief History of Cleverness", we find that every invention actually has a bridging process, all to solve new problems, there are new inventions when there is a need, in the book these inventors are called smart people, but I think they are just better at discovering and thinking.
