think and how they behave. Three of the best known examples of such a revolutionary effect are Nicolaus Copernicus, who wrote De revolutionibus orbium coelestium (1543); Charles Darwin, who wrote On the Origin of Species (1859); and Sigmund Freud, who wrote The Interpretation of Dreams (1899). These three highly influential, and initially very controversial, works changed the way people understood their place in the world. Copernicus's heliocentric view of the cosmos displaced humans from their previously accepted place at the center of the universe; Darwin's evolutionary theory placed humans firmly within, as opposed to above, the order of manner; and Freud's ideas about the power of the unconscious mind overcame the belief that humans were consciously in control of all their own actions. Translator Translators have the task of finding some equivalence in another language to a writer's meaning, intention and style. Translators whose work has had very significant cultural effect include Al-Ḥajjāj ibn Yūsuf ibn Maṭar, who translated Elements from Greek into Arabic and Jean-François Champollion, who deciphered Egyptian hieroglyphs with the result that he could publish the first translation of the Rosetta Stone hieroglyphs in 1822. Difficulties with translation are exacerbated when words or phrases incorporate rhymes, rhythms, or puns; or when they have connotations in one language that are non-existent in another. For example, the title of Le Grand Meaulnes by Alain-Fournier is supposedly untranslatable because "no English adjective will convey all the shades of meaning that can be read into the simple [French] word 'grand' which takes on overtones as the story progresses." Translators have also become a part of events where political figures who speak different languages meet to look into the relations between countries or solve political conflicts. It is highly critical for the translator to deliver the right information as a drastic impact could be caused if any error occurred. Reportage Blogger Writers of blogs, which have appeared on the World Wide Web since the 1990s, need no authorisation to be published. The contents of these short opinion pieces or "posts" form a commentary on issues of specific interest to readers who can use the same technology to interact with the author, with an immediacy hitherto impossible. The ability to link to other sites means that some blog writers – and their writing – may become suddenly and unpredictably popular. Malala Yousafzai, a young Pakistani education activist, rose to prominence due to her
