When it comes to language, we will immediately think of many beautiful and catchy ancient texts that have been passed down through the ages.

Poetry, analyzing the text, we will find how far-reaching the meaning of this word is in ancient times;

When it comes to literary thought, we can trace it back to Confucius and Mencius and Confucianism, but when it comes to it,

The word "math" seems to be just numbers, letters,

Calculations, equations, parabolas, etc. What we can do is to calculate and solve problems related to mathematics.

The question is, as to how these things came into being and why, we don't know. Say "no"

I am often fortunate to read famous American mathematicians, mathematical historians, educators,

Maurice Klein, a philosopher and applied physicist, is a profound and immortal book, which shows people the main creations of mathematics from the origin of Babylon and Egypt to the beginning of the 20th century. This masterpiece revolves around the main concepts of mathematical thought and the people who have contributed to it, providing people with an overview of the development of mathematics and revealing the unity hidden behind the unrelated branches of this subject today. After reading this book, I feel that the process of reading this book is our mathematics teaching.

Educators' journey to find roots. Although the book mentioned that "in order not to make information messy, I"

Ignore several cultures, such as China, Japanese and Mayan cultures, because of their works.

Writing has no significant influence on the mainstream of mathematical thought, which also makes me slightly disappointed.

Let me talk about my feelings after reading this book:

(1) The history of mathematics is the history of human development.

Exhibition history,

The process of mathematics depends largely on the process of history.

Humans are advanced animals,

In the gradual evolution, due to various needs of life, mathematics gradually came into being.

For example, the edge of a corner is usually defined by

It is characterized by spontaneous movements of the thighs or arms. In English, two sides of a right triangle are called two arms. In primitive times

In civilization,

The application of mathematics is limited to simple transactions,

By BC

600

annual

300

Over the years,

Earlier clay tablets are of great significance to the history of mathematics, and at this time, preliminary words have appeared.

Babylonians are even more.

60

Carry marks are applied to the base, and scores are also represented by carry marks.

And square, square root,

Cubes and cube root tables. And the mathematical knowledge at this time.

Has been used to dig canals,

Build dams and engage in other water conservancy projects.

At the peak of BC,

In the past three centuries,

The application of mathematics has increased,

Especially counting the sun and planets.

Exercise.

With the progress of human civilization to the classical period, mathematics has produced several university schools.

Several universities

The school has produced its own unique views through exchange and learning.

Thales Luck of the Ionian School

The solar eclipse was predicted with mathematical knowledge,

I also used a full-length pole.

By simultaneously

Measure the length of rod shadow and pyramid shadow,

Find the height of the pyramid.

Pythagoras studies

Triangular numbers and ternary arrays have come out. During the three major pressure periods,

Euclidean

principle

A book has become an important book on the history of mathematics.

With the emergence of the Third Reich,

mathematics

It occupies a dominant position in the three academic circles of Yali.

And the great mathematicians who appeared in this period.

Jimmy will find the area and volume by exhaustive method and work it out.

Pi?

. Not only that, he also invented a kind of

A water pump for pumping water from a river uses a lever to move a heavy object and uses the focusing characteristics of a parabolic mirror.

He also shone concentrated sunlight on besieged Rome, set it on fire and burned it. With the evolution of history,

The development of mathematics has also declined several times. But here we are.

16

In the 20th century, due to the increasing development of silver.

Business and business activities need better arithmetic,

Transoceanic geographical exploration needs people.

Scientists have more accurate astronomical knowledge,

A better astronomical table needs to be compiled,

This needs more.

Accurate trigonometric function table. Finally, the technical work of craftsmen, especially the construction and manufacture of cannons.

And projectile motion,

Need quantitative thinking.

Under these required pressures,

The progress of algebra has also accelerated. reach

18

By the end of the century, "analytic geometry" had become the standard.

At the same time, calculus and infinite series also entered mathematics.

(2) Don't separate mathematics from physics.

By reading this book,

I was deeply impressed by several mathematicians.

Accept.

If I only knew the founder of Plato's idealism,

But I don't know Plato's performance on mathematics.

Deductive structure has made great contributions;

We only know Archimedes theorem in physics,

But you can't

Knowing that he was the greatest mathematician in ancient times,

His mathematical work includes finding the sum of areas by exhaustive method.

Volume, in addition,

He is also an excellent astronomer; All we know is that Newton proposed

The law of universal gravitation was introduced,

I didn't know he was a great chemist,

In mathematics, about differential product

Points, he also summed up many developmental ideas, and in

1736

Mathematics published in 1998

Close the "flow number method and infinite series"

. These people tell us that there is independence between disciplines.

Field, more inseparable from the relationship.

(3) Mathematics comes from life.

I can't help feeling when I close the book.

Mathematics is actually a product of life.

Things, knots are used for counting,

60

Counting the base is also for counting, as a person.

The progress of quasi-civilization,

People full of wisdom not only meet the needs of life, but also make mathematics develop.

The exhibition is faster. reach

2 1

Century, with the progress of science, the popularity of computers, big data.

With the arrival of a generation, I think mathematics will be synchronized with science and great changes will take place. The history of mathematics is a book.

Endless scrolls, because human civilization has not stopped.
