He was once a world-renowned scientific star.
But suddenly "disappeared" when he became famous
He has been incognito for 17 years.
Lead the team to develop nuclear **.
Hold up China's status as a nuclear power!
He is a famous nuclear physicist.
One of the main founders of China's nuclear development.
Wang Ganchang. 
He spent his whole life.
Fulfilled the promise he made:
I would like to pledge my country."
10 December 1998.
Wang Ganchang passed away.
Today, let's reminisce together.
This great scientist has hidden his merits and fame.
In 1907, Wang Ganchang was born in a family of traditional Chinese medicine in Fengtangcang, Zhitang Town, Changshu City, Jiangsu Province. The family had a prosperous life, but unfortunately, when Wang Ganchang was 4 years old, his father died of illness, and his mother died when he was 13 years old. Although his family's financial situation is much worse than before, Wang Ganchang still did not give up his Xi. With the support of his grandmother and his own efforts, he went all the way from a rural private school in Jiangsu to Tsinghua University.

During the few years of his university studies, Wang Ganchang experienced the Western powers' treatment of China, personally felt the weakness and incompetence of the Western powers, and witnessed the brutal killing of his classmates, and he was indignant. Teacher Ye Qisun told him excitedly: "Only science can save our nation." Wang Ganchang remembered this sentence for a lifetime, and also practiced this sentence with his life.
After graduating from Tsinghua University, Wang Ganchang was admitted to the government of Jiangsu Province as an international student and went to the University of Berlin in Germany to study Xi under the physicist Ms. Meitner.
Meitner was a pioneer of nuclear physics in the world, and was called "a female scientist as talented as Marie Curie" by Einstein.
During his four years at the University of Berlin, Wang Ganchang published many influential publications, which caused great repercussions in the physics community. He was deeply admired by Meitner for his scientific rigor, extraordinary scientific insights, and broad experimental ideas.
In 1932, after listening to an academic lecture, Wang Ganchang questioned the physical phenomena and conclusions involved in the report, and at the same time thought of a new experimental method. Overjoyed, Wang Ganchang twice offered his advice to his mentor Meitner.
The renowned nuclear physicist Meitner underestimated the Chinese lad's creativity this time, and she twice rejected Wang's application.
Later, British physicists used similar experimental methods to Wang Ganchang, discovered neutrons, and won the Nobel Prize in Physics in 1935. This is the first time Wang Ganchang has missed the Nobel Prize.
In 1934, Wang Ganchang, who obtained a doctorate, resolutely chose to return to China despite the retention of his supervisor. At that time, the country was in the period of the Anti-Japanese War, and the conditions were difficult as you can imagine. His fellow German scientists advised him: "Science knows no borders, China is very backward, and there are no conditions for scientific research that you need, so why should you go back?"”
However, Wang Ganchang said: "Although science has no borders, scientists have national boundaries. As a Chinese, my motherland is suffering unjustly, and I want to go back to serve her!”
After returning to China, Wang Ganchang first taught at Shandong University, and then came to Zhejiang University at the invitation of Zhu Kezhen.
During the Anti-Japanese War, Zhejiang University moved many times, traveled more than 2,600 kilometers through six provinces in the south of the Yangtze River, and finally took root in a ruined temple in Zunyi.
At the same time, in the continuous relocation, Wang Ganchang has never stopped scientific research. In a humble environment, he made phosphor zinc sulfide, which filled the gap in scientific research for the country.

At that time, the legend of "neutrino" was circulating in the world physics community, but no one could confirm its existence. In the case of tuberculosis, Wang Ganchang studied neutrino detection under an oil lamp. In 1942, the American journal Physical Review published Wang Ganchang's "Suggestions on Neutrino Detection". This ** caused a sensation, but due to the limited experimental conditions in China, he failed to put it into practice.
In 1953, the American scientist Leynes was inspired by this article to capture neutrinos in a nuclear reactor for the first time, and won the Nobel Prize in Physics in 1995. Wang Ganchang missed it again.
In 1955, Wang Ganchang was elected as an academician of the Chinese Academy of Sciences. In 1956, Wang Ganchang came to the Dubna Joint Institute of Nuclear Research in the Soviet Union. As the team leader, he formed a research team with nuclear experts from 12 countries and discovered the anti-sigma negative hyperon, which shocked the world!

At that time, there were many people, and the achievement achieved by Wang Ganchang and his team will definitely be able to win the Nobel Prize in Physics. But at this moment, Wang Ganchang, who has attracted much attention and expectation from the international physics community, suddenly disappeared from people's sight ......
One day, Wang Ganchang, who works at the Dubna Institute, received a secret telegram from his return to China: "Stop the work in hand and immediately return to China to accept a new task." Therefore, he resolutely put down the research work he was familiar with and returned to his motherland, and secretly participated in the development of the atomic bomb.
In the face of the urgent needs of the country, Wang Ganchang gave up his research direction and turned to nuclear research. When asked whether he was willing to change his name for the development of nuclear weapons, Wang Ganchang wrote "Wang Jing" without hesitation and said loudly: "I am willing to pledge my life to the country."

Wang Ganchang, who is in his 50s, is the oldest scientist in the test base, but he overcomes all kinds of difficult conditions, and does every experiment himself, often working late into the night despite his tiredness, often with a glass of steamed bread and water, and immediately puts himself into work after eating.

From 1961 to 1963, Wang Ganchang led thousands of explosive detonation tests of atomic bomb initiating devices. Finally, on October 16, 1964, China's first atomic bomb was successful!
After that, Wang Ganchang secretly participated in the development of China's first hydrogen bomb.
In 1978, Wang Ganchang finally bid farewell to the identity of "Wang Jing" and returned to the China Institute of Atomic Energy. At this time, people discovered that the "Wang Jing" researcher at the nuclear research base turned out to be the famous Wang Ganchang.
In 1999, Wang Ganchang was awarded the "Two Bombs and One Star" Meritorious Service Medal. At this time, his name was finally made public. However, Wang Ganchang failed to receive the honor in person. On December 10, 1998, Wang Ganchang passed away at the age of 91.
From the prime to the gray temples.
He wrote it all his life.
The selflessness and responsibility of a Chinese scientist.
Salute to Wang Ganchang!
