Fang Lizhi
Fang Lizhi (also Li-Zhi; February 12, 1936 – April 6, 2012) was a Chinese astrophysicist, vice-president of the University of Science and Technology of China, and activist whose liberal ideas inspired the pro-democracy student movement of 1986–87 and, finally, the Tiananmen Square protests of 1989. Because of his activism, he was expelled from the Chinese Communist Party in January 1987. For his work, Fang was a recipient of the Robert F Kennedy Human Rights Award in 1989, given each year to an individual whose courageous activism is at the heart of the human rights movement and in the spirit of Robert F. Kennedy's vision and legacy. He was elected an academician of the Chinese Academy of Sciences in 1980, but his position was revoked after 1989. Life and career in China Fang was born on 12 February 1936 in Beijing. His father worked on the railway. In 1948, a year before the People's Liberation Army took over the city, as a student of the Beijing No. 4 High School, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Anti-Rightist Campaign
The Anti-Rightist Campaign () in the People's Republic of China, which lasted from 1957 to roughly 1959, was a political campaign to purge alleged "Rightists" within the Chinese Communist Party (CCP) and the country as a whole. The campaign was launched by Chairman Mao Zedong, but Deng Xiaoping and Peng Zhen also played an important role. The Anti-Rightist Campaign significantly damaged democracy in China and turned the country into a ''de facto'' one-party state. The definition of rightists was not always consistent, often including critics to the left of the government, but officially referred to those intellectuals who appeared to favor capitalism, or were against one-party rule as well as forcible, state-run collectivization. According to China's official statistics published during the "Boluan Fanzheng" period, the anti-rightist campaign resulted in the political persecution of at least 550,000 people. Some researchers believe that the actual number of persecuted is between ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Soviet Union
The Soviet Union,. officially the Union of Soviet Socialist Republics. (USSR),. was a transcontinental country that spanned much of Eurasia from 1922 to 1991. A flagship communist state, it was nominally a federal union of fifteen national republics; in practice, both its government and its economy were highly centralized until its final years. It was a one-party state governed by the Communist Party of the Soviet Union, with the city of Moscow serving as its capital as well as that of its largest and most populous republic: the Russian SFSR. Other major cities included Leningrad (Russian SFSR), Kiev (Ukrainian SSR), Minsk ( Byelorussian SSR), Tashkent (Uzbek SSR), Alma-Ata (Kazakh SSR), and Novosibirsk (Russian SFSR). It was the largest country in the world, covering over and spanning eleven time zones. The country's roots lay in the October Revolution of 1917, when the Bolsheviks, under the leadership of Vladimir Lenin, overthrew the Russian Provisional Government ...

Cultural Revolution
The Cultural Revolution, formally known as the Great Proletarian Cultural Revolution, was a sociopolitical movement in the People's Republic of China (PRC) launched by Mao Zedong in 1966, and lasting until his death in 1976. Its stated goal was to preserve Chinese communism by purging remnants of capitalist and traditional elements from Chinese society. The Revolution marked the effective commanding return of Mao –who was still the Chairman of the Chinese Communist Party (CCP)– to the centre of power, after a period of self-abstention and ceding to less radical leadership in the aftermath of the Mao-led Great Leap Forward debacle and the Great Chinese Famine (1959–1961). The Revolution failed to achieve its main goals. Launching the movement in May 1966 with the help of the Cultural Revolution Group, Mao charged that bourgeois elements had infiltrated the government and society with the aim of restoring capitalism. Mao called on young people to "bombard the headqu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Liaoning
Liaoning () is a coastal province in Northeast China that is the smallest, southernmost, and most populous province in the region. With its capital at Shenyang, it is located on the northern shore of the Yellow Sea, and is the northernmost coastal province of the People's Republic of China. Historically a gateway between China proper and Manchuria, the modern Liaoning province was established in 1907 as Fengtian or Fengtien province and was renamed Liaoning in 1929. It was also known at that time as Mukden Province for the Manchu name of ''Shengjing'', the former name of Shenyang. Under the Japanese-puppet Manchukuo regime, the province reverted to its 1907 name, but the name Liaoning was restored for a brief time in 1945 and then again in 1954. Liaoning borders the Yellow Sea ( Korea Bay) and Bohai Sea in the south, North Korea's North Pyongan and Chagang provinces in the southeast, Jilin to the northeast, Hebei to the southwest, and Inner Mongolia to the northwest.

Laser Physics
Laser science or laser physics is a branch of optics that describes the theory and practice of lasers. Laser science is principally concerned with quantum electronics, laser construction, optical cavity design, the physics of producing a population inversion in laser media, and the temporal evolution of the light field in the laser. It is also concerned with the physics of laser beam propagation, particularly the physics of Gaussian beams, with laser applications, and with associated fields such as nonlinear optics and quantum optics. History Laser science predates the invention of the laser itself. Albert Einstein created the foundations for the laser and maser in 1917, via a paper in which he re-derived Max Planck’s law of radiation using a formalism based on probability coefficients ( Einstein coefficients) for the absorption, spontaneous emission, and stimulated emission of electromagnetic radiation. The existence of stimulated emission was confirmed in 1928 by Rudol ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Solid State Physics
Solid-state physics is the study of rigid matter, or solids, through methods such as quantum mechanics, crystallography, electromagnetism, and metallurgy. It is the largest branch of condensed matter physics. Solid-state physics studies how the large-scale properties of solid materials result from their atomic-scale properties. Thus, solid-state physics forms a theoretical basis of materials science. It also has direct applications, for example in the technology of transistors and semiconductors. Background Solid materials are formed from densely packed atoms, which interact intensely. These interactions produce the mechanical (e.g. hardness and elasticity), thermal, electrical, magnetic and optical properties of solids. Depending on the material involved and the conditions in which it was formed, the atoms may be arranged in a regular, geometric pattern ( crystalline solids, which include metals and ordinary water ice) or irregularly (an amorphous solid such as common ...

Particle Physics
Particle physics or high energy physics is the study of fundamental particles and forces that constitute matter and radiation. The fundamental particles in the universe are classified in the Standard Model as fermions (matter particles) and bosons (force-carrying particles). There are three generations of fermions, but ordinary matter is made only from the first fermion generation. The first generation consists of up and down quarks which form protons and neutrons, and electrons and electron neutrinos. The three fundamental interactions known to be mediated by bosons are electromagnetism, the weak interaction, and the strong interaction. Quarks cannot exist on their own but form hadrons. Hadrons that contain an odd number of quarks are called baryons and those that contain an even number are called mesons. Two baryons, the proton and the neutron, make up most of the mass of ordinary matter. Mesons are unstable and the longest-lived last for only a few hundredths of ...
