Ahmed Sofa (Bengali: আহমদ ছফ, June 30, 1943 – July 28, 2001) was a well-known Bangladeshi poet, novelist, writer, critic, translator and intellectual. He wrote novels, poetry and non-fiction essays. He also translated the writings of others. Ahmed Sofa was renowned for his intellectual righteousness as well as his holistic approach to the understanding of social dynamics and international politics.

Sofa helped establishing Bangladesh Lekhak Shibir (Bangladesh Writers' Camp) in 1970 to "organise liberal writers in order to further the cause of the progressive movement".

Born at Gachbaria in Chittagong district, Sofa's career as a writer began in the 1960s. He never married. On 28 July 2001, Ahmed Sofa died in a hospital in Dhaka. He was buried in Martyred Intellectuals' Graveyard.

Ahmed Sofa's outspoken personality and bold self-expression brought him into the limelight. At the same time, he was very affectionate towards the younger generation, who gathered around him. He was never seen hankering after fame in a trivial sense. He was a secular thinker.

Joseph Beuys (German pronunciation: [ˈjoːzɛf ˈbɔʏs]; May 12, 1921 – January 23, 1986) was a German Fluxus, Happening and performance artist as well as a sculptor, installation artist, graphic artist, art theorist and pedagogue of art.

His extensive work is grounded in concepts of humanism, social philosophy and anthroposophy; it culminates in his "extended definition of art" and the idea of social sculpture as a gesamtkunstwerk, for which he claimed a creative, participatory role in shaping society and politics. His career was characterized by passionate, even acrimonious public debate, but he is now regarded as one of the most influential German artists of the second half of the 20th century.

Joseph Beuys was born in Krefeld, the son of the merchant Josef Jakob Beuys (1888–1958) and Johanna Maria Margarete Beuys (born Hülsermann, 1889–1974). The parents had moved from Geldern to Krefeld in 1910, and Beuys was born there on May 12, 1921. In autumn of that year the family moved to Kleve, an industrial town in the Lower Rhine region of Germany, close to the Dutch border. There, Joseph attended primary school (Katholische Volksschule) and secondary/high- school (Staatliches Gymnasium Cleve, now the Freiherr-vom-Stein-Gymnasium). His teachers considered him to have a talent for drawing; he also took piano- and cello lessons. On several occasions he visited the studio of the Flemish painter and sculptor Achilles Moortgat. Other interests of note include Nordic history and mythology and especially the natural sciences. According to his own account, when the Nazi Party staged their book-burning in Kleve on May 19, 1933 in the courtyard of his school, he salvaged the book Systema Naturae by Carl Linnaeus "...from that large, flaming pile".

Andy Warhol (August 6, 1928 – February 22, 1987) was an American artist who was a leading figure in the visual art movement known as pop art. His works explore the relationship between artistic expression, celebrity culture and advertisement that flourished by the 1960s. After a successful career as a commercial illustrator, Warhol became a renowned and sometimes controversial artist. The Andy Warhol Museum in his native city, Pittsburgh, Pennsylvania, holds an extensive permanent collection of art and archives. It is the largest museum in the United States of America dedicated to a single artist.

Andy Warhol's artwork ranged in many forms of media that include hand drawing, painting, printmaking, photography, silk screening, sculpture, film, and music. He was a pioneer in computer-generated art using Amiga computers that were introduced in 1985, just before his death in 1987. He founded Interview Magazine and was the author of numerous books, including The Philosophy of Andy Warhol and Popism: The Warhol Sixties. Andy Warhol is also notable as a gay man who lived openly as such before the gay liberation movement. His studio, The Factory, was a famous gathering place that brought together distinguished intellectuals, drag queens, playwrights, Bohemian street people, Hollywood celebrities, and wealthy patrons. Warhol has been the subject of numerous retrospective exhibitions, books, and feature and documentary films. He coined the widely used expression "15 minutes of fame". Many of his creations are very collectible and highly valuable. The highest price ever paid for a Warhol painting is US$100 million for a 1963 canvas titled Eight Elvises. The private transaction was reported in a 2009 article in The Economist, which described Warhol as the "bellwether of the art market". Warhol's works include some of the most expensive paintings ever sold.

Marcel Duchamp (28 July 1887 – 2 October 1968; French pronunciation: [maʁsɛl dyˈʃɑ̃]) was a French artist whose work is most often associated with the Dadaist and Surrealist movements. Considered by some to be one of the most important artists of the 20th century, Duchamp's output influenced the development of post-World War I Western art. He advised modern art collectors, such as Peggy Guggenheim and other prominent figures, thereby helping to shape the tastes of Western art during this period.

Duchamp challenged conventional thought about artistic processes and art marketing, not so much by writing, but through subversive actions. He famously dubbed a urinal art and named it Fountain, though in a 1917 letter to his sister Duchamp indicates that a female friend, possibly the Baroness Elsa von Freytag-Loringhoven, conceived of the urinal as sculpture and sent it to him under the pseudonym Richard Mutt. Duchamp produced relatively few artworks, while moving quickly through the avant-garde circles of his time.

The 2006 transatlantic aircraft plot was a terrorist plot to detonate liquid explosives carried on board at least 10 airliners travelling from the United Kingdom to the United States and Canada. The plot was discovered and foiled by British police before it could be carried out and, as a result, unprecedented security measures were immediately put in place.

The restrictions were gradually relaxed in the following weeks, but the ability of passengers to carry liquids onto commercial aircraft is still limited.

Of the approximately 24 suspects who were arrested in and around London on the night of 9 August 2006, eleven were charged with terrorism offences on 21 August, two on 25 August (subsequently discharged on 1 November), and a further three on 30 August. Eight men (Ahmed Abdullah Ali, Assad Sarwar, Tanvir Hussain, Oliver Savant, Arafat Khan, Waheed Zaman, Umar Islam, Mohammed Gulzar) were charged in connection with the plot. The trial began in April 2008 and ended in September. The jury failed to reach a verdict on charges of conspiracy to kill by blowing up aircraft, but the court did find three guilty of conspiracy to murder. In September 2009, a second trial (of the eight men excluding Gulzar but with the addition of Donald Stewart-Whyte) found Ali, Sarwar, and Hussain guilty of the plot.
