"You score 98
It's because you can only score 98
And xueba test 100 points
It's because it's only 100 points on the paper."
This paragraph
Putting it on someone else may be a little exaggerated
But if it is placed on Yu Min, who is known as the "father of the hydrogen bomb" in China
But it seems to be "small"
One year, Peking University's algebra exam was very difficult
The average grade for the Mathematics Department is less than 20 points
However, Yu Min of the Physics Department scored 100 points
This caused a sensation throughout the Peking University campus
Yu Min in his youth
In today's terms
Yu Min is a genius who impresses Juncai
A "learning god" who can crush the school bully
It's just that such a "god-like figure"
However, it "disappeared" in the academic circle for a full 28 years
He spent half his life alone
In exchange for the "thunder" that shocked the world
With a lifetime of diligence and wisdom
A full-score answer sheet was handed over to the state
Today is the 96th anniversary of the birth of "two bombs and one star" Yu Min
Let's go back in his footsteps
Recall the life of this full-score "learning God" who dedicated himself to the country
Multiple Choice Question: Continue Your Studies or Serve your country?
August 16, 1926
Yu Min was born in Ninghe County, Hebei Province
Lutai Town (present-day Ninghe District, Tianjin).
Yu Min's family was not wealthy
His parents saved money to provide him with education
This developed his precocious and sensible character
In 1944, the year before the victory of the War of Resistance Against Japan
At the age of 18, Yu Min was admitted to Peking University with excellent results
Enrolled in the Faculty of Engineering
Two years later, he transferred to the Faculty of Science
Since then, he has been associated with theoretical physics for life
Yu Min and his parents as a teenager
Talented Yu Min
He completed his undergraduate and postgraduate studies at Peking University
He has performed well and achieved outstanding results
In the minds of teachers and classmates
Is a remarkable "good seedling"
His teacher, Mr. Zhang Zongxuan, once praised
"I've been teaching all my life
Never seen such a good student as Yu Min! ”
If you continue to study
Yu Min will definitely achieve impressive results in the field of physics
He himself was full of confidence
On the one hand, he worked as a teaching assistant at Peking University
While preparing for a new shock to the peak of physics
Yu Min (first from left) in college with his classmates
However, fate took a turn in 1951
Yu Min, who has just been a teaching assistant for less than a year
Was taken to a "secret" place -
The first in New China
Nuclear Science and Technology Research Base
Institute of Modern Physics
Reception yu min's
He is the founder of the cause of nuclear science on the mainland
Mr. Peng Huanwu
Two Bombs and One Star Meritorious Scientist Peng Huanwu, founder of China's nuclear science cause
It turned out that Mr. Peng Huanwu had already heard about Min's excellence
After many considerations
He decided to invite Yu Min to join
Institute of Modern Physics, Research Center for Nuclear Science
Serve the nation together
At that time, it was concentrated here
Top talent in all nuclear fields in China
Such as Deng Jiaxian, Huang Zuqia, Jin Xingnan and so on
For such an invitation
Yu Min agreed without hesitation
He grew up in the War of Resistance Against Japan
The atrocities committed by the great powers against China
A bloody mark was left in his heart
He is well aware of the importance of nuclear weapons for national defense
The statement said:
"Since childhood, I have been very bitter about the oppression of the nation
For the security of the motherland
I am willing to serve the cause of the country and the nation
Contribute everything yourself. ”
In this way, face the multiple choice of life
Yu Min gave up further education
Joined the Nuclear Theory Group
It took just a few short years
It has mastered the essence of international nuclear physics
He has also written a number of heavyweight papers
These papers
Directly let the continent's nuclear research
Rise to new heights
In 1957, he was awarded the Nobel Prize in Physics
Japanese expert Shinichiro Asagaga visited China
When he learned that Yu Min had never been abroad
He has not been guided by any famous foreign teacher
Study alone
After being able to obtain such a huge research result
Marvel at the fact that he is China's "domestic soil expert No. 1"
Fill-in-the-blank question: If you want an atomic bomb, ____ must also be fast
It is precisely on the road of nuclear theory research that Yu Min is on the road
When it comes to the fore
November 1, 1952
The world's first hydrogen bomb developed by the United States
Exploded on a small island in the Marshall Islands of the Pacific Ocean
The Soviet Union was not to be outdone
There was a scramble to carry out hydrogen bomb tests
As one mushroom cloud after another rises
The top of all humanity's heads is covered with a nuclear shadow
January 15, 1955
Chairman Mao Zedong in Zhongnanhai
He presided over an enlarged meeting of the Secretariat of the Central Committee
The development of nuclear weapons has been put on the timetable for the construction of new China
Chairman Mao pointed out
"Atomic bombs are scary, we don't necessarily use them
But since it's scary, we must have it too! ”
He also stressed
"If you want an atomic bomb, you must have a hydrogen bomb!"
In order to break the international nuclear monopoly and nuclear blackmail
The continent is under extremely difficult conditions
Under the guidance of the policy of "independence and self-reliance"
Tighten the waistband of your pants
Unswervingly develop atomic and hydrogen bombs
Who is responsible for the development of the hydrogen bomb?
Qian Sanqiang, then vice minister of the Third Ministry of Machinery Industry
I thought of Yu Min, who was very capable
A day in January 1961
Qian Sanqiang invited Yu Min to his office
Tell him: "After studying in the institute, report to the superior for approval."
Decide to involve you in a pre-study of the thermonuclear weapons principles. ”
Qian Sanqiang, a meritorious scientist of two bombs and one star and the founder of China's nuclear science cause
For Yu Min, who is obsessed with the study of atomic nucleus theory
Turn to hydrogen bombs for pre-study
Not his interest
But Yu Min once again resolutely agreed
"Patriotism trumps interest," he said
Everything I learned in the past can be thrown away,
Be sure to go all out to get the hydrogen bomb out! ”
Since then, Yu Min's name has been in the field of nuclear theory
Even the entire physics community "evaporated"
He dug a void in his life
to fill in the blanks needed by another home country
Years later, Yu Min recalled
"A person's name, sooner or later, is going to be without
He can integrate his own meager strength into the strength of the motherland
It was enough to live a life of consolation. ”
Judgment question: Is the authoritative data of foreign countries credible?
Yu Min joined the hydrogen bomb study
The first question to face is
Deuterium-deuterium fusion, deuterium-tritium fusion, and tritium-tritium fusion
Exactly which thermonuclear reaction is suitable for hydrogen bombs
At that time, an authoritative scientific journal in the United States published a paper
A new data was released
Indicates that adding tritium to the design facilitates the detonation of hydrogen bombs
This is good news for the development of hydrogen bombs
The question is, is this data true?
Both deuterium and tritium are scarce and difficult to obtain materials
If you want to do experimental verification
It takes 3 years and hundreds of millions of yuan
At that time, China was facing a severe external situation
Can't afford to spend this money
Can't afford to wait that long
Yu Min chose to use a pen and scratch paper for theoretical verification
After a lot of calculus, this data was rejected
Avoiding a detour in hydrogen bomb research
Later, someone abroad repeated the experiment
Prove that the journal's data is indeed wrong
October 16, 1964
The first atomic bomb on the mainland exploded successfully
Premier Zhou Enlai immediately deployed:
Must have been before 1968
Conduct a hydrogen bomb device explosion test!
Time is of the essence
Yu Min and team researchers
Immerse yourself almost all the time
Mountains of data are being calculated
Finally, in 1965, the hydrogen bomb development program was initially formed
To verify that the scheme works
Yu Min led dozens of researchers
Rush to Shanghai "Hundred Days Battle"
Shanghai has the only computer in China that performs 50,000 operations
However, 95% of the time is guaranteed first
Atomic bomb design calculations
Yu Min led his team
Even put the abacus, the slide rule
These original tools are used
He buried himself in it
Tens of thousands of calculus papers, calculation tapes
From a large number of dense,
In a clutter of data
With extraordinary physical intuition
Gradually sort out the clues and find the key
Finally formed a set
A basic complete solution from the principle of the hydrogen bomb to the configuration
It took less than five years
Yu Min went from a completely ignorant hydrogen bomb
"Domestic Soil Expert No. 1"
It's all about independence
It has broken through the blockade of the theoretical technology of hydrogen bombs by nuclear powers
More with the sensational "Yu Min scheme"
Developed a hydrogen bomb for China
A door opened
Q&A: For what is the lifelong struggle?
Once the principle of hydrogen bombs was broken
Everyone was scrappy
I want to build a hydrogen bomb immediately
However, the principle of the hydrogen bomb still needs to be tested by nuclear tests
The nuclear test site is far away in the Great Northwest
The living conditions are quite harsh
Eat steamed buns mixed with sand
Drink bitter alkali water
The vast Gobi fly sand and stones
The wind was like a knife
Winter temperatures are minus 30°C
The road was frozen like a washboard
The bitterness of life can be overcome by gritting your teeth
The suffering that can be pressed on people's hearts all the time
But it is the most difficult to say
At a seminar prior to a nuclear test
Stress and tension filled the room
At this time, all I heard was —.
"On the day of the subject's appointment, he slept restlessly, and the food was not sweet...
The subject bowed down to exhaustion, and after death has been..."
Yu Min and Chen Nengkuan, two scientists, suddenly
You will do it sentence by sentence
Zhuge Liang's "Table of Renunciation" was recited to the end
At that moment, everyone in this room
All were moved to tears...
June 17, 1967
A fighter plane over Lop Nur in Xinjiang
A parachute was dropped
The hydrogen bomb test officially began
Accompanied by a thunderous sound
Two suns rise simultaneously over the desert
Mushroom clouds rose from the ground
On the same day, Xinhua News Agency released it to the world
The Press Communiqué solemnly declares:
"Today, China's first hydrogen bomb
Successful explosion over the western part of China! ”
From the first atomic bomb to the hydrogen bomb
It took seven years and three months in the United States
It took the Soviet Union six years and three months
It took four years and seven months in the UK
France took eight years and six months
And China took only two years and eight months
China's hydrogen bomb came from scratch
It's all a product of autonomy
It is the most authentic made in China
Yu Min used his obscure efforts
In exchange for China's "blockbuster" in the world
September 18, 1999
Yu Min accepted it at the Great Hall of the People
"Two Bombs and One Star" Meritorious Scientist Medal
It was also on this day
Yu Min, Cheng Kaijia, Wang Ganchang and other scientists
The identity that has been hidden for nearly 30 years is really declassified
Fifteen years later, Yu Min, 89 years old
It also won the 2014 National High-tech Award
Yu Min in a wheelchair
Look back on your own scientific research process
Calmly said:
"I wholeheartedly agree that nuclear weapons would be better to ban them completely
However, we cannot do without nuclear weapons
The Chinese nation does not bully others
But we must not be bullied by others! ”
What kind of cause should people strive for all their lives?
Yu Min's motto can answer this question:
"As a leaf without weight, I am willing to dedicate my life to grand planning"
Give up the small self for the big me
It was Yu Min's lifelong answer without regrets
A multiple-choice question that chooses the path of a lifetime
A fill-in-the-blank question fills the gap in the field of national defense
A judgment question identifies an independent development path
A question and answer question has inspired countless later generations to contribute to the country
Yu Min's answer sheet did not contain his own name
There is only a brightly colored "one hundred"
He is proud of his feats in casting nuclear shields
Today, let us be sensitive together
Protect the country and maintain peace
Help the nation to stand up
"Learning God" Yu Min deserves it!
