The bank's work is not tense, but the burden of life is not easy. In the following years, he has been one of the main undertakers of the family economy. Prices jump several times a day, and money falls vertically like a broken kite, which makes him feel the hardships of life. Nevertheless, he scrimped and saved some money from his meager salary and bought some favorite astronomical literature.
Attracted by the charm of the starry sky, he hoped that others could share the beauty of the universe, so he embarked on the road of astronomical popularization. 1946, he published the first popular science essay in Shanghai Ta Kung Pao, introducing the principle and phenomenon of solar eclipse. Then, he boldly wrote his first book, the 50,000-word science fiction "Colony of the Earth", which tells an imaginary story of flying to the moon.
2.1In the summer of 976, Wang Xuan invented the high-speed information compression technology of high-resolution glyphs (the compression multiple reached 500∶ 1) and the high-speed restoration method.
It is the first to design a special chip to improve the speed of font recovery, so that the speed of Chinese font recovery reaches the leading level of 700 words per second. For the first time in the world, control information (or parameters) is used to describe the characteristics of stroke width and corner shape, so as to ensure the symmetry and width consistency of strokes after font size is reduced.
3. 1964, Yuan Longping began to study hybrid rice. 1966, IRRI Philippine International Rice Research Institute bred miracle rice (IR8).
Nanyou 2, the first strong hybrid rice combination bred from 1974, successfully developed hybrid rice seed production technology on 1975, which laid the foundation for large-scale popularization of hybrid rice. 1985 put forward the strategic idea of hybrid rice breeding, and pointed out the direction for the further development of hybrid rice.
1986, Yuan Longping put forward the hybrid rice breeding strategy, which divided the hybrid rice breeding method into three strategic development stages: three-line method, two-line method and one-line method, that is, the breeding program developed from complex to simple and efficient; Judging from the utilization level of heterosis, it can be divided into three strategic development stages: the utilization of heterosis among varieties, the utilization of heterosis among subspecies and the utilization of distant heterosis, that is, the utilization of heterosis is developing in an increasingly strong direction.
Qian Xuesen loved the motherland and science since he was a teenager. Later, he went to the United States to study aerodynamics, put forward "Carmen-Qian formula" with his teacher, and founded engineering cybernetics. After the founding of New China, he actively requested to return to China to participate in the construction. After five years of obstruction and persecution, he finally returned to the motherland, and he was praised as a people's scientist.
5. Deng Jiaxian is one of the founders of China's theoretical research on nuclear weapons. As early as his youth, he set up the ideal of becoming a powerful country through science and technology. From 65438 to 0948, he went to Purdue University in the United States to study abroad and obtained a doctorate in physics.
1950 give up the excellent working and living conditions abroad and return to the motherland. In order to develop national defense research, he was willing to be an unsung hero and struggled in obscurity for decades. He organized and led the basic theoretical research on detonation physics, fluid mechanics, equation of state, neutron transport, etc., made a lot of simulation calculation and analysis on the physical process of atomic bomb explosion, and took the first step of China's independent research and design of nuclear weapons.
