Demon School

Stephen Hawking's popular science works are called "A Brief History of Time", "The Universe in the Husk", Freeman-Dyson's popular science works are called "Cosmic Waves", "All-round Infinity", "Sun, Genome and Internet" , "Imaginary World", the names are very high, and I know it is a very powerful book.

So what is the name of my book changed? Lu Qiujian thought about it for a moment, um, just use Da Liu's classic sentence in "Chao Wen Dao"! At the top of the document, he typed the words "When Humans Start to Look at the Starry Sky".

"When humans start to look up at the starry sky, then they are only one step away from uncovering the ultimate mystery of the universe." Thanks to Da Liu, Lu Qiujian can no longer find this sentence more suitable as the beginning of his article.

The most important factor that promotes the development of human science and technology is curiosity. When human beings become curious about the starry sky, he will use his imagination to guess the hidden secrets in the starry sky.

Humans first determined the time, direction, and calendar by observing the sun, moon, and other celestial bodies and celestial phenomena. . The ancient Egyptians discovered that the rising water of the Nile River in the delta region coincided with the rise of the sun and Sirius at the horizon. They set the time between the occurrence of this phenomenon as one year, a total of 365 days. The whole year is divided into 12 months, 30 days per month, and the remaining 5 days are used for festivals; at the same time, the year is divided into 3 seasons, namely "flooding season", "growing grain season", "harvest season", 4 months per season.

The ancient Chinese found that the moon's profit and loss cycle can be used to measure the length of the year, and found that the twelve full moons are one year old. This discovery is one of the most accurate results of the early calendar.

The Stonehenge built by the ancient British on Great Britain can accurately understand the 12 positions of the sun and moon, and observe and estimate the rise and fall of the sun, moon and stars in different seasons.

Ancient Greek Thales carried out the first predicted total solar eclipse; Meton discovered that the moon's phase repeats on the same date of the current solar calendar on a 19-year cycle; Odox proposed the concentric movement of the sun, moon and stars around the earth; Parmenides and Democritus argued that the earth is spherical, thinking that the morning star and the faint star are the same Venus. It is also proposed that the Milky Way is made up of many dense stars; Anasagora proposed the cause of the lunar eclipse, and believed that the moon is bright due to the reflection of sunlight.

The Romans, Arabs, Mayans, Indians, etc. each proposed their own understanding of the mysteries of the universe, and made progress in different fields.

In the process of human beings exploring the ultimate mystery of the universe. They found the most powerful tool—that is, mathematics. Through mathematics, they can process all kinds of data collected through observations for a generation. At the same time, there are many data that cannot be directly obtained by observation, so mathematical knowledge such as logarithm, spherical coordinate system and trigonometric functions are generated.

At the same time, with the deepening of human observation of the universe, their requirements for observation tools are getting higher and higher, and the manufacture of these tools also requires superb knowledge of mathematics, physics, and chemistry. After Newton used the classical mechanics system to describe the macro world in mathematical language, mathematics and astronomy became more and more closely connected. Non-Euclidean geometry and calculus developed rapidly under the demand of astronomy.

In modern times, whether it is Einstein's theory of relativity or Gamoff's theory of the Big Bang. Many advanced data tools have been borrowed. It can be said that human beings cannot achieve today's scientific and technological achievements without mathematics.

Lv Qiujian intends to start with the development of mathematics, gradually unveiling the process of human beings gradually revealing the ultimate mystery of the universe using mathematics as a tool, which will also be interspersed with some knowledge of physics and chemistry.

What he wants to do is not just to tell people these conclusions, but more importantly, to show the scientific methods of mankind in the process of pursuing the ultimate mystery of the universe, bold assumptions and precise verification, so as to rule out those wrong guesses and draw the correct theory. .

The test-oriented education currently implemented by Hua Guo has guaranteed the fairness of education to a certain extent, and cultivated a batch of useful talents in a short time, but it is not without its shortcomings. Examination-oriented education often pays more attention to conclusions and ignores the process; in order to obtain better results in the exam, teachers usually let students remember those important conclusions, such as formulas, definitions, and so on. It ignores the derivation of the process that produced these conclusions.

Doing so has created a series of problems. People tend to pay attention to the process of ignoring results, but know that in scientific research, processes are often more important than results.

And when telling these conclusions, some inappropriate examples and methods are often used. For example, Newton was smashed by an apple and his head flashed brightly and discovered the secret of gravity. A steam engine.

These stories have left a deep impression on people, that is, as soon as the aura of light flashes, an invention will suddenly appear! This is one of the important reasons for the emergence of scientific delusions.

Admittedly, Edison also said that success equals 1% inspiration and 99% sweat, but I think that 1% inspiration is more important than 99% sweat ~ www.mtlnovel .com ~ But inspiration also needs foundation. If Newton does not have deep knowledge of mathematics and physics, then he will not think of gravity from apples; there are so many apple trees all over the world. He is not the only one who is hit by an apple in the head. Most people probably only wipe the apple and eat it. Only Newton found the mystery of gravity.

In the same way, there are countless housewives who see the lid of the teapot being lifted by steam, but they will only turn off the fire and use the boiling water to make tea to brew coffee. .

Therefore, in this book, Lu Qiujian not only wants to tell people these conclusions, but also wants to show the production process of these conclusions to all readers, so that after reading this book, they have a relatively scientific understanding of science, not I will admire the tall nouns such as gravitational waves and material waves, and express my opinions without thinking.

It is obviously not an overnight matter to complete such a book, and the most important thing about popular science is that it is easy to understand and interesting. If it is as difficult as writing a paper, no one will read it, so this requires a long process.

However, he is not in a hurry. Anyway, he is gradually idle now. Some of them have time to complete, and now it is not the right time to sell even if it is written; as for the best sales opportunity, he already has a plan in his heart, just waiting An award is announced! (To be continued.)
