1. “Two bombs and one satellite”

background:

1. New China faces “nuclear threat”

"A country without nuclear weapons is not a great power" - Charles de Gaulle (French military strategist)

2. The Soviet Union refused to help China develop nuclear weapons.

What is "two bombs and one satellite"?

Atomic bombs, missiles, satellites

After accepting the task of developing an atomic bomb, Deng Jiaxian said to his wife: "From now on, my life will be handed over to this work. I can no longer take care of my family affairs and my two children."

① Deng Jiaxian knew that there would soon be a "worldwide nuclear ban." If China cannot complete the nuclear limit test before this time, it will be "banned" and will not be able to become a "great power". Therefore, Deng Jiaxian has been scrambling for time. He has forgotten the time of his own life and all other time. He only wants China to escape from being beaten and bullied.

② Deng Jiaxian and others completed the tasks of five generations of scientists from other countries in one generation, going from atomic bombs to neutron bombs to hydrogen bombs to the nuclear limit simulated by computers in one go.

③Our country exploded its last atomic bomb on the tenth anniversary of Deng Jiaxian’s death, and then announced its participation in the nuclear ban the next day.

④For Deng Jiaxian, "hero" means that he contributed to China becoming a contemporary great power, not just "military merit".

⑤ After an atomic bomb failed, several units were shirking responsibility. In order to find the real reason, someone must go to the place where the atomic bomb shattered and retrieve some important parts. Deng Jiaxian said: "No one should go, I will go in. You can't find it if you go, it will be polluted in vain. I did it, I know it." He walked into that area, which means death. He quickly found the 7-nuclear warhead, held it in his hands, and walked out. It turned out to be a problem with the parachute.

⑥It was this time that the cause of his death from radiation was buried.

Think about it: What noble qualities of Deng Jiaxian are reflected in the above materials?

The noble spirit of patriotism and selfless dedication

The development of my country’s aerospace technology:

(1) In June 1964, the self-developed launch vehicle took off, writing a glorious page in my country’s aerospace history.

(2) In 1970, my country successfully launched the first man-made earth satellite, Dongfanghong 1, using the Long March carrier rocket, becoming the fifth country in the world to independently launch man-made satellites after the Soviet Union, the United States, France, and Japan. Earth satellite country.

(3) In 1999, my country successfully launched the first unmanned spacecraft "Shenzhou-1".

Yuan Longping and indica hybrid rice

Yuan Longping’s contributions:

The hybrid rice successfully cultivated by Yuan Longping has great historical and practical significance.

(1) The increase in unit grain output has opened up a new way for my country's agricultural production to significantly increase, thus producing huge economic and social benefits.

(2) It not only solves the problem of eating for the Chinese people to a large extent, but is also considered to be the magic weapon to solve the problem of hunger in the entire world. The Western world calls Yuan Longping's hybrid rice "Oriental Magic Rice." Internationally, hybrid rice is regarded as China’s “fifth greatest invention after the four great inventions in ancient times.”

(3) Practice brings true knowledge. Through his long-term practice, Yuan Longping proposed a new theory of rice hybridization and achieved a historic breakthrough in rice breeding. The successful cultivation of hybrid rice has brought my country's hybrid rice technology to the world's advanced level, proving the great role of scientific development in promoting the national economy.

Yuan Longping won the highest international agricultural award---World Food Award
