2. Astronomical Calendar: This is the content of Chapter 3. From the perspective of the history of science, astronomy is mathematics and things.
The hometown of Neo-Confucianism is a rich source of mathematical problems and discoveries.
Operation and seasonal changes not only make people feel the laws of nature, but also arouse people's endless.
Imagination and awe, so we launched an endless journey of knowledge. Cao An arranged this chapter,
There are his hobbies and his foresight.
3. Geometry and trigonometry: This is the content of the second, fifth, sixth, seventh and eighth chapters, including the plane.
Three-dimensional and spherical situations. This part is from materials, viewpoints, interests, ways of thinking to beauty.
Appreciation has Cao Cao's unique appreciation, which can make up for the boring mathematics in senior high school.
4. Calculus: This is the content of Chapter 4 and Chapter 9. Nature uses calculus to act on the earth, but
It is not easy to master calculus, which has become the most headache course for freshmen. Chief administrative officer
In the short thirty-five pages of chapter 9, the development of calculus for more than two thousand years is briefly introduced.
Be clear. Therefore, the author suggests that young students, if they want to learn calculus for the first time, might as well pass.
Chapter 9: Cut in and read intensively to ensure that you can enter the calculus class happily and directly.
Be very careful and cherish the first time in your life.
5. Scientific methodology: This is the content of chapters 10, 12 and 14. Scientific methods include statistical methods.
And all kinds of speculative reasoning in mathematics. The latter, such as induction and division.
Keywords analysis and synthesis, analogy, trial and error, popularization, specialization (or extreme), dimensional test,
Symmetry observation, local reasoning, bold assumption, careful verification, imagination, and so on.
The former is roughly divided into three levels: one is to collect data, the other is to sort out, compare and analyze data.
Third, put forward assumptions, draw conclusions, explain what is known and predict what is unknown. Cao chose the black dragon.
Formula (actually initiated by Archimedes), created by Columbus, discovered by America, and Darwin.
In 2000, Mendel explored famous examples, such as genetic laws, to illustrate the application of scientific methods. all of these are
This is an excellent topic for studying the history of mathematics, the history of science and the philosophy of science. The author especially likes chapter 12.
The exploration process of Black Dragon Formula is a complete process from discovery and proof to appreciation and methodology.
It's really great.
6. Chaos and fragmentation: This is the content of chapter 1 1, which is a new science in recent years and is related to computers.
Intimate relationship. In order to catch up with the times, Cao worked tirelessly, devoted himself to research and reused his popularity.
Introduce words to readers.
7. Mathematics education and problem solving: This is the content of chapters 12, 13 and 14. Problem solving training is mathematics.
The core work of education. The philosopher Schopenhauer said:
When a person is trapped by a problem, the problem gradually occupies the whole body and mind, if he can find it.
A solution, then he will become a philosopher. Schopenhauer's problem here refers to
A big problem in philosophy. In fact, we changed "problem" into "mathematical problem" and "philosophy"
It is also feasible to change "home" to "mathematician". In view of this, the most important thing in mathematics education is to let students learn.
Students gain experience in solving problems independently, from which they can exercise their ideological strength and perseverance. Cao cited many examples.
Readers can imitate the "preaching" of solving problems on the spot, and then find out what suits them best.
A road. Only when a person has tasted the pleasure of solving problems independently will he like mathematics and mathematics.
And unforgettable for life, leading to lasting pursuit.
Is math interesting? Ask nine and a half out of ten middle school students to say no to you, except to despise everything.
Gu's people don't say anything, and most of the rest of the students should still be able to earn support. At least put those
Generally speaking, there are more people who are willing to pay $ $ for chaos than those who are pure Benjamin. Cao brand gourd paste
The object to be sold is these edge elements. Cao started from the aspects of literature and history, and also covered the history of mathematics.
Evolution, from Euclid geometry and calendar calculation to calculus, probability statistics and even chaos fragmentation, finally returns to the past.
Zong discussed the basic principles of using mathematical tools. However, its content is not divorced from high school mathematics knowledge.
The feeling of learning this book is quite different from that of textbooks and reference books. No one will think that it is included in textbooks and reference books.
Many examples will be interesting, but why are they boring? Because mathematics is associated with people.
Interrupted, then lost the human touch, natural "people" will not be interested in these contents. This link, ah
Grass not only helps us find it, but also combines the two more closely, making readers feel that the object of study is not.
It is only mathematics, but another aspect of the overall development of human civilization.
O 'Keerid said, "There is no imperial way to learn geometry." You mustn't read math, and neither should you.
Those who can "read" should rely on their own deduction and calculation, plus Cao's understanding of various problems in the book.
The derivation of the solution is mostly just a formality, and there is no detailed flow; Geometry problems show pictures at most, and so does the ability to explain.
Very limited. Therefore, Cao may say, "There is no paradise for learning mathematics." I believe Cao wrote it.
The purpose is to let readers think for themselves, follow in the footsteps of their ancestors and enjoy learning mathematics.
Interesting, can really absorb this knowledge. The best application object of this book is teenagers who are studying. Let them go.
Before losing confidence and interest in mathematics and physics completely, it is most useful to correct it with Cao's specific medicine.
For ordinary readers, the gourd of Cao Cao is also a popular science book with both connotation and practicality.
At least we have different choices. If our textbooks can be written in the way of this book,
Those marginal people who wander at the entrance of the hall of mathematics and science will surely take their steps, cross the threshold and see the elegance of science.
That's great. Cao Cao's gourd contains medicine from heaven, but this kind of fun has to be experienced by himself, and no one else can help it.
I feel it for you.
