Children are the continuation of life, but also the future of a family, in the development of high-tech today, the cultivation of children's interest, the strengthening of knowledge, the expansion of thinking has become the top priority of every parent on the road to education, and the choice of popular science books has also become a part of the test of parents' golden eyes.
As 4 to 12 years old children, their cognitive level of calculation problems and problem solving is still relatively shallow, often still in the sensory stage, need to absorb knowledge through observation, the most effective way is to use the form of comics to intuitively and simply enhance children's interest in calculation problems, so as to open their eyes, expand their thinking, let them absorb a variety of computing knowledge in comics, and use comics to stimulate the senses to help absorb knowledge.
"A Brief History of Cleverness: Computational Thinking in History (Picture Book Edition)" will take children to understand the calculation problems in history and the stories of smart people who solved these problems in the form of comic science, which can be used as a mathematical popular science book and a historical storybook.
For calculation, in our cognition, the earliest tool for learning to calculate is abacus, with the continuous progress of the times, this tool will only appear in the textbooks of primary school students, it is estimated that most people have forgotten how to use the abacus.
A higher level than abacus is the calculator, the primary electronic products replaced the previous bulky, complicated abacus operation, successfully brought computing to a higher level, and then the more advanced is artificial intelligence and quantum computers. So in the backward ancient period, how did those ancients solve the problem of computing?
The book is divided into 14 chapters, which will start from the initial calculation to today's high-tech products such as computers and artificial intelligence, take children to understand the history and secrets of computing, let children glimpse the wonderful context of history in hundreds of exquisite illustrations, and build a new cognitive system.
The reason why this book is divided into 14 chapters is because from ancient times to the present, human beings have used 14 inventions to show the great role of computational thinking in history.
For example, in ancient times, most people used fingers, stones, and knots to count and calculate in arithmetic, but this algorithm is obviously only suitable for the calculation of a few items, and when faced with a large number of soldiers, this knot method cannot play a role in calculation.
So people invented abacus, using these ordinary sticks to calculate large amounts. The ancient celebrity Zu Chongzhi used the calculation chip to calculate the value of pi to the last 7 decimal places.
This book explains calculations while supplementing celebrity strange things to strengthen the knowledge points of this section, and adds knowledge expansion after each chapter, can you imagine that the calculation chips used for calculations were created as idioms by the literati inkers? Like a plan, a strategist, a better shot...
We will all use the abacus but do not know the source of the abacus, it turned out that it appeared in the Han Dynasty of our country, as long as you write down the catchy abacus recipe, even children are easy to learn.
During the Ming Dynasty, the abacus practitioner Cheng Dawei perfected the abacus technique originally used for calculation, which greatly improved the overall calculation speed.
Not only does our country have abacus, but other countries also have all kinds of abacuses, such as the ancient Greek counting board, the ancient Roman ditch abacus, the Western European line abacus, the Russian abacus...
With the rapid development of the times, more and more data need to be calculated and solved, obviously the abacus can not meet the huge amount of calculation, and then there are slide rules, adders, punch card watchmakers, electronic computers, high-level languages, operating systems, application software, Internet, smart phones, big data, artificial intelligence and quantum computers.
From this book, we see that the computing problem has undergone a long and rich transformation from the calculation to the quantum computer, and the invention of each intelligent person has brought mankind to a higher level of intelligence, they have made mankind go through several periods of computing development, showing the process of the evolution of human intelligent minds, and also allowing children to glimpse the highlight moments of computing development in the long river of history.
