(en français)Un lecture politique, sociologique et psychanalytique: Il y a chez Tintin quelque chose qui défie le temps, les langues et les cultures. La qualité du dessein et des scénarios n'explique pas tout. Le récit est solidement ancrée dans une réalité vérifiable et les sujets sont toujours d'actualité. Le but de cette présentation est de raconter, à l'aide de certains Albums, le déroulement de la création Hérgéenne où l'imaginaire se nourrit d'une réalité faite de thèmes d'actualité et de détails circonstanciés d'une extrême précision. Cette présentation vous fait revenir de plus près sur les grands événements, extérieurs ou personnels, qui ont émaillé la vie d'Hergéet influencé son œuvre. Enfin les aventures de Tintin seront décryptées en tant qu'une vaste fresque qui parle... more >>

(This talk will be presented in English) The human visual system is equipped with a remarkable capacity to extract and represent depth information from flat images cast on the back of each eye. This aspect of visual perception is integral to representing the relative location and structural properties of objects in the field of view. Advances in understanding how this phenomenon unfolds in the conscious mind have led to the advent of technologies that allow us to see 3-dimensional (3D) images presented on flat cinema and/or television screens. The entertainment industry which is a major component of Western culture has had a recent history of success using this technology to attract viewers to movie theatres and to market home entertainment units... more >>

John Locke (29 August 1632 - 28 October 1704), widely known as the Father of Liberalism, was an English philosopher and physician regarded as one of the most influential of Enlightenment thinkers.

His writings influenced Voltaire and Rousseau, many Scottish Enlightenment thinkers, as well as the American revolutionaries. His contributions to classical republicanism and liberal theory are reflected in the American Declaration of Independence. Locke's theory of mind is often cited as the origin of modern conceptions of identity and the self, figuring prominently in the work of later philosophers such... more >>

CaféLitt is not a place; it is a gathering of minds. We are a group of mostly Persian young students, scholars and professionals who gather every Thursday evening around 19h00 in a café to discuss various subjects and share different ideas, ranging vastly from history to science, from literature to fine arts. We started these gatherings on Jan 18th, 2007. Each week, one of us takes the responsibility of presenting a topic (in Persian, English or French) for about an hour in a subject s/he is intimately familiar with or has an expertise in. Afterwards, the evening turns into a discussion forum and all members of the audience will have an opportunity to ask their question(s) and share their points of view.
CaféLitt is open to all comments, suggestion, collaboration and new ideas. CaféLitt provides an unparalleled opportunity for learning about culture, science and philosophy in a relaxed and friendly environment, and for sharing your knowledge and expertise with like-minded members of your community.
CaféLitt is officially registered as a non-profitable group and is a nonpartisan, nonreligious and nonpolitical entity.
