Liu Hui (fl. 3rd century) was a mathematician of the state of Cao Wei during the Three Kingdoms period of Chinese history. In 263, he edited and published a book with solutions to mathematical problems presented in the famous Chinese book of mathematics known as The Nine Chapters on the Mathematical Art (九章算术).
He was a descendant of the Marquis of Zixiang of the Han dynasty, corresponding to current Zixiang township of Shandong province. He completed his commentary to the Nine Chapters in the year 263.
He probably visited Luoyang, and measured the sun's shadow.
Along with Zu Chongzhi, Liu Hui was known as one of the greatest mathematicians of ancient China. Liu Hui expressed all of his mathematical results in the form of decimal fractions (using metrological units), yet the later Yang Hui (c. 1238-1298 AD) expressed his mathematical results in full decimal expressions.
Liu provided commentary on a mathematical proof identical to the Pythagorean theorem. Liu called the figure of the drawn diagram for the theorem the "diagram giving the relations between the hypotenuse and the sum and difference of the other two sides whereby one can find the unknown from the known".
Liu Xiaobo (born 28 December 1955) is a Chinese literary critic, writer, professor, and human rights activist who called for political reforms and the end of communist single-party rule in China. He is currently incarcerated as a political prisoner in China.
Liu has served from 2003 to 2007 as President of the Independent Chinese PEN Center, an organization funded by the National Endowment for Democracy, which in turn is almost entirely funded by the US Congress. He was also the President of NED-funded MinZhuZhongGuo (Democratic China) magazine since the mid-1990s. On 8 December 2008, Liu was detained because of his participation with the Charter 08 manifesto. He was formally arrested on 23 June 2009 on suspicion of "inciting subversion of state power." He was tried on the same charges on 23 December 2009, and sentenced to eleven years' imprisonment and two years' deprivation of political rights on 25 December 2009.
During his fourth prison term, he was awarded the 2010 Nobel Peace Prize for "his long and non-violent struggle for fundamental human rights in China." He is the first Chinese citizen to be awarded a Nobel Prize of any kind while residing in China. Liu is the third person to be awarded the Nobel Peace Prize while in prison or detention, after Germany's Carl von Ossietzky (1935) and Burma's Aung San Suu Kyi (1991). Liu is also the second person (the first being Ossietzky) to be denied the right to have a representative collect the Nobel prize for him.

Genres: ,They put the treasure deep inside us
Inside us, inside us
They thought the desert would divide us
Divide us, divide us
With silence
They filled our hearts and hands with violence
With violence, with violence
It's time to leave the fields behind us
Behind us, behind us
