Edward Rolf Tufte ( /ˈtʌfti/; born 1942) is an American statistician and professor emeritus of political science, statistics, and computer science at Yale University. He is noted for his writings on information design and as a pioneer in the field of data visualization.

Edward Rolf Tufte was born in 1942 in Kansas City, Missouri, to Virginia Tufte and Edward E. Tufte. He grew up in Beverly Hills, California, and graduated from Beverly Hills High School. He received a BA and MS in statistics from Stanford University and a PhD in political science from Yale. His dissertation, completed in 1968, was entitled The Civil Rights Movement and Its Opposition. He was then hired by Princeton University's Woodrow Wilson School, where he taught courses in political economy and data analysis while publishing three quantitatively inclined political science books.

In 1975, while at Princeton, Tufte was asked to teach a statistics course to a group of journalists who were visiting the school to study economics. He developed a set of readings and lectures on statistical graphics, which he further developed in joint seminars he subsequently taught with renowned statistician John Tukey, a pioneer in the field of information design. These course materials became the foundation for his first book on information design, The Visual Display of Quantitative Information.

Aaron Swartz (born November 8, 1986) is an American programmer, writer, political organizer and Internet activist. He is best known in programming circles for co-authoring the RSS 1.0 specification. He received mainstream media attention after his federal indictment and arrest on 19 July 2011, for allegedly harvesting academic journal articles from JSTOR.

Swartz is the co-founder of Demand Progress and the Progressive Change Campaign Committee. He currently lives in Brooklyn, New York.

Swartz was active in discussions of Internet standards from an early age, and co-authored the specification for RSS by the time he was 14.^{[citation needed]} Since then he has been a member of the W3C's RDF Core Working Group, co-designed the formatting language Markdown with John Gruber, and worked on many other projects.

Swartz attended Stanford University for a year, leaving to start the software company Infogami, a startup that was funded by Y Combinator's first Summer Founders Program. Infogami was built around a wiki backend, a subject of interest for Swartz since his early effort to develop theinfo, a wiki-based encyclopedia, in 2000.

Yann Tiersen (born 23 June 1970) is a musician from France. His musical career is split between studio albums, collaborations and film soundtracks with a distinctive sound that is always involved. It can be recognized by its use of a large variety of instruments; primarily the guitar, synthesizer or violin together with instruments like the melodica, xylophone, toy piano, harpsichord, accordion and typewriter.

Tiersen is often mistaken as a composer of soundtracks, himself saying "I'm not a composer and I really don't have a classical background", but his real focus is on touring and studio albums which just happen to often be suitable for film. His most famous soundtrack for the film Amélie was primarily made up of tracks taken from his first two studio albums.

Yann Tiersen was born in Brest in the Finistère département in Brittany in northwestern France, in 1970, into a family of Belgian and Norwegian origins. He started learning piano at the age of four, violin at the age of six, and received classical training at several musical academies, including those in Rennes, Nantes, and Boulogne. In the early 1980s when he was a teenager he was influenced by the punk subculture, and bands like The Stooges and Joy Division. In 1983, at the age of 13, he broke his violin, bought an electric guitar, and formed a rock band. Tiersen was now living in Rennes, and this turned out to be the perfect place for his musical career. In fact, Rennes is home to the three-day music festival Rencontres Trans Musicales, held annually in December, giving him the opportunity to see acts like Nirvana, Einstürzende Neubauten, Nick Cave and the Bad Seeds, The Cramps, Television, and Suicide. A few years later, when his band broke up, Tiersen bought a cheap mixing desk, an 8-track reel-to-reel audio tape recording, and started recording music solo with a synthesizer, a sampler, and a drum machine.

Zhang Ziyi (born 9 February 1979), sometimes credited as Ziyi Zhang, is a Chinese film actress. Chinese media have called her one of the Four Young Dan Actresses (四小花旦) in China's film industry, along with Zhao Wei, Xu Jinglei and Zhou Xun.

Her first major role was in The Road Home (1999). She achieved fame in the West after leading roles in Crouching Tiger, Hidden Dragon (2000), Rush Hour 2 (2001), House of Flying Daggers (2004), and Memoirs of a Geisha (2005). She has been nominated for three BAFTA Awards and a Golden Globe Award.

Zhang was born and raised in Beijing to Zhang Yuanxiao, an accountant and later economist, and Li Zhousheng, a kindergarten teacher. She is very close to her older brother, Zhang Zinan (Chinese: 章子男; pinyin: Zhāng Zǐnán; born 1973). Zhang began studying dance when she was 8 years old; subsequently, she joined the Beijing Dance Academy by her parents' suggestion at the age of 11. While at this boarding school, she noticed how mean the other girls were to each other while competing for status amongst the teachers. Zhang disliked the attitudes of her peers and teachers so much that, on one occasion, she ran away from the school. At the age of 15, Zhang won the national youth dance championship and began appearing in television commercials in Hong Kong.
