Brief introduction of Ding Zhaozhong

Ding Zhaozhong, male,/kloc-0 was born in Ann Arbor, Michigan, USA on October 27th, 1936, and his ancestral home is Rizhao, Shandong, China.

/kloc-0 received a bachelor's degree in physics from the university of Michigan in 1959, a doctor's degree in physics from the university of Michigan in 1962, and anti-deuterium was discovered in 1965. The electron radius is measured at 1967, and it is found that the electron has no volume, and the radius is less than 10e- 14cm.

1969, he measured the transformation between ordinary light and light with mass (that is, vector mesons), and proved that high-energy ordinary light can be transformed into vector mesons. In the same year, he was a professor in the physics department of MIT. 1975 was elected as an academician of the American Academy of Arts; 1974 The fourth quark bound state-J particle was discovered.

Therefore, he was awarded the Lorenz Prize of 1975 and the Nobel Prize in Physics of 1976 by the American government. 1977 was elected as a member of the National Academy of Sciences; Glue injection was found in1979; 1989 only three generations of neutrinos were identified. From 65438 to 0994, he led AMS experiments to find antimatter and dark matter in space. In the same year, he was elected as a foreign academician of China Academy of Sciences.

1998, it was first discovered in space that the spatial distribution of helium -4 and isotope helium -3 was different. In 20 15, it was first discovered that there were a large number of high-energy positrons in space, and the sources of these positrons were probably produced by dark matter collisions.

1936 65438+1October 27th, Ding Zhaozhong was born in Ann Arbor, Michigan, USA. His father Ding and his mother Wang Juanying both teach in universities. Two months after her birth, Ding Zhaozhong returned to China with her mother.

1948, Ding Zhaozhong went to Taiwan with his parents, first attending Fengyuan Datong Primary School, then attending Taipei Chenggong Middle School, and one year later transferred to Jianguo Middle School.

In the summer of 1972, Ding Zhaozhong experimental group used the 3.3× 10 10eV proton accelerator of Brookhaven National Laboratory in the United States to search for long-lived hitting particles with the mass between (1.5 ~ 5.5 )× 109EV.

199 1 Ding Zhaozhong delivered a speech entitled "The Spirit of Unity of Knowing and Doing" when he received the special honor award in the Great Hall of the People. This speech is recorded in lesson 13, Unit 4, Grade 8, Chinese version, and lesson 14, Unit 4, Grade 9, People's Education Edition.
