Chapter 242: Classification of the world line (thanks to the leader of the code-named black boss
be honest.
After traveling to the dungeon of 1850 and receiving the Halo mission.
There are two main things that Xu Yun is most interested in.
The first nature is the growth of wheat.
After all, this man ranks third in the history of physics, second only to Einstein and Mavericks.
At the same time, it is different from Mavericks in the 1665 copy and Lao Su in the 1100 copy.
The current dungeon is not a short-lived novice mission, and Xiaomai is completely different from Lao Su who is entering the end of his life. He is a pure blank sheet of paper.
in this case.
With the help of someone like Xu Yun who came from later generations to hang on the wall, how far can Xiaomai be trained to grow?
The most conservative thing to say.
The two years he wasted when he was falsely told by Faraday to be dictated by the Royal Society could at least be saved in the future, right?
Not to mention that Xu Yun can't only do this little, and his help to Xiaomai will obviously not be limited to this.
The anticipation of witnessing the growth of the elder is really exciting.
As for the second thing Xu Yun is interested in?
Naturally, this is a copy after the timeline has been changed. How far has the scientific level developed?
This is also the knowledge he must understand to be able to carry out actions in the future.
Electric lights and nitroglycerin appeared more than 20 years earlier, but what about other things?
Is it possible that some "big guys" will appear in advance?
It was with this thought in mind that Xu Yun called Mai and came to the library to find the truth today.
The light on the second floor of the library is a bit darker than the first floor, and the electric lights these days are not as bright as those in later generations, so the layout of the seats on the second floor is completely different from the small desks in many traditional libraries.
Its seats are generally long tables by the window, which are similar to the high tables and stools of later bar bars. They are highly utilized but may not be as comfortable.
Xu Yun randomly chose a location with relatively bright light and looked around a few times.
I don’t know if it’s because school hasn’t started yet.
This area occupies a quarter of the second floor of the library, and there is only one person besides Xu Yun.
It was a middle-aged man of about forty years old, wearing a light purple shirt. His specific appearance could not be seen clearly, but his shiny forehead was very conspicuous.
No wonder Xu Yun felt that the light in this area was brighter.
There was a pile of books piled next to this person, his head buried, and he was concentrating on taking notes.
Judging from the age, this should be a professor or teaching assistant who is preparing lessons.
Xu Yun didn't pay too much attention. He withdrew his gaze, pulled out a chair, sat on it, and began to read the book he had originally planned.
Mentioned it a long time ago.
Later generations of Mavericks did not leave an autobiography except for some letters. The most authoritative work on his life is "The Biography of Newton" written by James Gleick, which sells for about 50 yuan.
But this copy is different.
Mavericks left an autobiography in this copy called "My Life".
Although the content is only 50,000 to 60,000 words, it narrates many details in the real timeline that future generations cannot know.
influenced by.
There are also many more authoritative biographies of Mavericks that are more in line with historical facts.
The more famous ones include "Into Newton", "Handbook of Conquering the Scientific World", "He Changed Europe", etc.
Although the book Xu Yun selected, "1650-1830: Two Hundred Years of Jump in the History of Science," is a little less famous.
But the author is the very famous William Ron Hamilton, the man who invented quaternions.
By 2022, the Hamiltonian is still one of the most basic concepts in mechanics.
At the same time, it is different from other biographies.
This book is written from a macro perspective, and the focus does not entirely stay on the calf.
Instead, it uses Mavericks' resume and contributions as a guide, and provides an overview spanning nearly two hundred years.
This is indeed the most suitable reference book for Xu Yun at present.
Then Xu Yun sat upright and opened the title page of the book.
After a while.
A preface comes into view:
[If the will to surrender is a country, then it must be called Gaul; if the projection of the god is a human being, then he must be called Isaac Newton]
"In the 16th and 17th centuries, a great scientific revolution emerged in Europe. It was the product of the Renaissance."
"The translation of a large number of ancient Greek and Roman documents in Arabic has aroused humanism and inspired mankind's enthusiasm to explore the real world and nature."
"The relationship between our planet and everything in the universe is undoubtedly an important area of discussion."
Hamilton's starting point is very good. At the beginning of this book, he first introduces an overview of the development of natural science before the 17th century.
The focus is on Copernicus's heliocentric theory and Kepler's three laws.
This is also the standard opening of many later books on the history of modern physics.
In order to facilitate later comparison, here is a brief introduction to the history of modern physics. Well, don’t worry, this time it’s in human words.
first.
The history of modern physics is mainly divided into two intervals:
16th-20th centuries, and 20th-21st centuries.
There is only one standard for how these two intervals are defined:
The discovery of X-rays in 1895.
Among them, the two cornerstones of physics in the 20th century are relativity and quantum theory, with the former being a classical physics system.
Our focus is on the 16th to 20th centuries, that is, the classical physics system.
Classical physics systems can also be divided into two categories using a less rigorous but simple classification:
Newtonian mechanical system, and analytical mechanics.
The latter can be divided into optics, thermodynamics, electromagnetism, etc.
Well, it's as simple as that. Going deeper is the individual achievements and contributions of specific scientists, such as Euler, Coulomb, and Faraday.
Xu Yun then continued to read.
"In April 1666, Isaac Newton derived the third-order formula of the 'Han Li expansion', which for the first time consolidated the self-propelled calculus model. Combined with Kepler's third law, he successfully derived the law of universal gravitation."
“In June of the same year, Isaac Newton discovered the dispersion of light.”
"In July 1667, the Black Death epidemic disappeared, London returned to normal, and Isaac Newton returned to Cambridge University."
"Two years later, he was awarded the Lucasian Professorship of Mathematics. He disclosed the results of his research on elastic forces at the Royal Society meeting in the same year and unilaterally defeated Robert Hooke."
“In 1673, Isaac Newton published Principles of Natural Philosophy and married Lisa Askew”
See here.
Xu Yun's expression suddenly shrank.
Timeline changes have occurred!
Before Mavericks got married to Lisa Escu, he had heard Xiaomai briefly say that they had no heirs, so this was still acceptable.
But the release of "Mathematical Principles of Natural Philosophy" is a bit surprising.
In Native History Lines.
The early Mavericks were always poor, so "Mathematical Principles of Natural Philosophy" would not be officially published until 1687 under the guidance of fanboy Halley.
And deduced based on the original copy.
With the emergence of Xu Yun, Mavericks has made a lot of money from ketchup, and his net worth is conservatively in the nine or tens of digits.
As soon as the wallet was full, "Mathematical Principles of Natural Philosophy" was naturally published in advance to 1679.
But in today’s timeline, the release date of this work has been moved much earlier!
The first line of Maverick's letter is [Mr. Fat Fish, five full years have passed since you left without saying goodbye]. At the same time, Xu Yun stayed in the copy until the beginning of 1666.
Therefore, the time when Mavericks wrote the letter was either 1671 or 1672.
In other words.
The book "Mathematical Principles of Natural Philosophy" should be the earliest theoretical collection that was born in advance due to the influence of Mavericks.
Then Xu Yun adjusted his breathing and continued reading.
"In 1668, Isaac Newton explained the dispersion phenomenon of light in terms of particle theory, and became the strongest supporter of the particle theory for a time."
"But in early 1672, Isaac Newton received a letter from his friend Fat Fish, which denied the absolute view of space and time founded by Isaac Newton, and assisted Isaac Newton in discovering the Newtonian spot."
"Later generations generally believe that without that transoceanic letter, Isaac Newton's life would have left a stain that is difficult to wash away, and the theoretical development of human physics would have wasted at least fifty years."
"After Mr. Newton was knighted and became the president of the Royal Society, universities in the UK and even Europe also tried to include some descendants of Eastern businessmen, but no one knew about the Fengling Yueying Sect."
Xu Yun flipped through page after page, and the appearance of physics architecture in this era became increasingly clear.
In general.
In this current era, there has been considerable acceleration in the theory of classical mechanics.
For example, the calculation of the gravitational constant.
Xu Yun demonstrated the Cavendish torsion scale in Lao Su's copy, and introduced Cavendish's calculation of the gravitational constant.
This is a wealthy second generation with the ultimate sociopathy. In 1798, he calculated the gravitational constant through homemade equipment.
And in this day and age.
It was still Cavendish who calculated the gravitational constant, but the time was advanced from 1798 to 1764.
Directly accelerated by 34 years.
However, Cavendish's other results have still not been announced. Facts have proved that this disease is still terminal even if you change the timeline.
Another example is in normal history.
It was not until 1846 that Neptune was predicted by Oppen Le Verrier through the formula of universal gravitation, and observed and confirmed as a planet by Johann Gottfried Galle.
This is also a landmark achievement of classical mechanics in the field of astronomy, which formally confirms the authority of the law of universal gravitation.
But in this current copy.
The observation time of Neptune was moved forward to 1811, and the physicist responsible for calculation and observation was replaced by William Herschel.
That's right.
It was the discoverer of Uranus.
in addition.
The mathematics and thermodynamics in the copy are also accelerated by different stages.
And the feedback of these theories in life is the reflection of many science and technology
Showed up early.
In addition to the electric lights and nitroglycerin mentioned earlier.
The generator originally invented by Siemens in 1866 was also born in 1831 ahead of schedule.
Now 20 years have passed.
The student dormitories of top universities like Cambridge University have completely universal power supply lines.
Another little-known Irish scientist, Cotton Bradford, invented color photography.
However, it is worth mentioning that
The first color photo in human history captured the scene of his wife being raped.
In 1801, the British mechanical engineer Bendtner designed a new bicycle style from the perspective of mechanics and kinematics.
He installed front forks and brakes, made the front and rear wheels the same size to maintain balance, and made a diamond-shaped frame out of steel pipes.
At the same time, rubber wheels were used for the first time, which led to the advent of modern bicycles 80 years ahead of schedule.
But what surprised Xu Yun was.
The two big guys, the internal combustion engine and the airplane, were not born in advance. It seems that history still has some inertia, and it is impossible to accelerate too fast.
all in all.
Judging from the current knowledge accumulation and productivity level.
Except that X-rays have not yet been discovered, the current productivity level of replicas is already infinitely close.
Around 1900.
"1900"
Xu Yun touched his chin, and another question suddenly came to his mind:
"It is said that the productivity level in the West has reached such a high level, how can the East survive until now?"
Again.
Although Xu Yun had no intention of extending his life or changing history towards the regime in the East.
But the background of this dungeon is too special. As a Chinese, Xu Yun's thinking cannot ignore the local area.
As we all know.
Europeans have been robbers since their ancestors. Of course there are gentlemen and international friends, but they are definitely not many.
There is original history for reference.
It is obviously illogical that they did not take action against the East even as productivity levels increased.
So why can the East survive until now?
Just when Xu Yun was having doubts, he suddenly felt that the light around him seemed to be much brighter.
He subconsciously raised his head and looked out the window and found that the sky was still gray and the sun had not risen yet.
A few seconds later.
He suddenly realized something and turned his head suddenly.
as expected.
I saw a big shining bald head standing next to him.
Xu Yun: ""
Note:
My previous work and rest schedule was so bad that my body was completely exhausted and I accidentally slept for 27 hours.
In addition, in the past few days, the entire chapter has been banned. The chapter everyone posted said that I can see it in the background, but it will not be displayed in the front desk, and it will be restored in a few days.
