From simple alphabets to secret symbolic languages, graphic designer Saki Mafundikwa celebrates the many forms of written communication across the continent of Africa. He highlights the history and legacy that are embodied in written words and symbols, and urges African designers to draw on these graphic forms for fresh inspiration. It's summed up in his favorite Ghanaian glyph, Sankofa, which means "return and get it" -- or "learn from the past."

Arithmetic and Geometric Sequences

From Boltzmann to quantum theory, from Einstein to loop quantum gravity, our understanding of time has been undergoing radical transformations. Carlo Rovelli brings together physics, philosophy and art to unravel the mystery of time.

Time is a mystery that does not cease to puzzle us. Philosophers, artists and poets have long explored its meaning while scientists have found that its structure is different from the simple intuition we have of it. Time flows at a different speed in different places, the past and the future differ far less than we might think, and the very notion of the present evaporates in the vast universe.

Carlo Rovelli is a theoretical physicist who has made significant contributions to the physics of space and time. He has worked in Italy and the US, and is currently directing the quantum gravity research group of the Centre de physique théorique in Marseille, France. His books 'Seven Brief Lessons on Physics' and 'Reality Is Not What It Seems' are international bestsellers translated into forty-one languages.

This talk and Q&A was filmed in the Ri on 30 April 2018.

Online lecture by Dr. Stefano Rizzo, Dr. Mohamad Saad, Dr. Sanjay Chawla.
This is the fourth lecture in the series "AI and Data Science for COVID-19 Data" lecture series by the Qatar Center for Artificial Intelligence.

Epidemiological models are compartmental models that simulate the evolution of infectious disease outbreaks. The results of an epidemic simulation strictly depend on the model’s parameters; biological and others related to demographics and lifestyle.

This lecture will introduce the simplest compartmental models. It will also show how it is possible to extend the traditional SIR model, with the final aim of simulating outbreak scenarios under different policies and country’s specifics.

Africa Program

After an introduction by Wilson Center President Jane Harman, Malawian President Mutharika proceeded to outline the initiative that he had begun, as Chairman of the Africa Union in 2010, on the African Food Basket.

"The greatest challenge facing humanity in modern times is not the threat of nuclear proliferation, but the threat to peace and security arising from failure to produce enough food to feed humanity" remarked President Mutharika. He noted, however, that with targeted investments and enhanced cooperation between African governments and international actors, Africa would be capable of feeding itself and the entire world.

Haiti is paying a heavy price for fighting for their freedom in 1791 and defeated the world's mightiest superpowers in 1804. We can beat them again and be self-sufficient but we must decolonize our minds. General #ToussaintLouverture showed us how to lead ourselves as brilliant statesmen and stateswomen, soldiers, and dedication to the Black Race. This is life or death for #Haiti, and for our future as a #BlackNation. We must help Haiti rise back to prominence. ⁣http://kevindorival.com

El Ciclo de Conferencias de Estudios Africanos y de la Diáspora Africana, ha sido creado para difundir el pensamiento Africano-centrado y PanAfricanista a través de las experiencias y los aportes de los Africanos y sus descendientes alrededor de mundo. Es un espacio abierto y permanente, donde se invitan expertos en diferentes áreas del conocimiento y donde el dialogo circunda en temas de interés colectivo y desde la perspectiva centrada en África, panafricana y anti-colonial.

Una Historicidad Cultural Africana: Escapando de la Trampa.

Los archivos históricos son un recuento de la historia, pero la versión que promueven no está tan cuestionada como debería ser. Las nuevas perspectivas y la promoción de miradas diversas son fundamentales para ayudar a redefinir el papel de la historia en la sociedad contemporánea. En su ensayo "Un extraño en la aldea", James Baldwin escribió "la gente está atrapada en la historia y la historia está atrapada en ellos." Allí, relata la experiencia de ser una persona negra en un pueblo de blancos en Suiza a principios de la década de 1950. Ahora imagine el mismo ensayo escrito por un escritor suizo blanco que relata la experiencia de un hombre negro en su aldea.

Los archivos capturan la historia en la medida en que consagran las perspectivas de quienes han tenido el privilegio de contarla y escribirla. Bajo el colonialismo, la historia está colonizada; es estar atrapados en la historia de otra persona (Arundhati Roy). La línea de tiempo histórica del colonizador se convierte en la línea de tiempo universal y lo que se da por sentado de eras y edades. ¿De quién es la prehistoria? ¿De quién es la antigüedad? ¿De quién es la Edad Media? ¿De quién es la modernidad? Yusef Doucet presenta una Historicidad Cultural Africana y nos invita a desafiar el estado monolítico unilateral de los anales de la historia, pero sobre todo, a escapar de su trampa.

[ENGLISH]

The Cycle of Conferences on African and the African Diaspora Studies [CEADA] invites to the conference “An African Cultural Historicity: Breaking Out the Trap” presented by Yusef Doucet.

The Cycle of Conferences on African and the African Diaspora Studies has been created to disseminate Afrocentric and Pan-Africanist thought through the experiences and contributions of Africans and their descendants worldwide. It is an open and permanent space where experts in different areas of knowledge are invited. The dialogue revolves around issues of collective interest and from the Afrocentric, Pan-Africanist, and anti-colonialist perspectives.

An African Cultural Historicity: Breaking Out the Trap.

The historical archives are a retelling of history, but the version they promote is not as questioned as it should be. New perspectives and the promotion of diverse points of view are critical to helping redefine the role of history in contemporary society. In his essay "Stranger in the Village," James Baldwin wrote, "people are trapped in history, and history is trapped in them." He recounts the experience of being black in a white village in Switzerland in the early 1950s. Now imagine the same essay written by a white Swiss writer recounting the experience of a black man in his village.

Archives capture history to the extent that they enshrine the perspectives of those who have had the privilege of telling and writing it. Under colonialism, history is colonized; it is being trapped in someone else's story (Arundhati Roy). The historical timeline of the colonizer becomes the universal and taken-for-granted timeline of eras and ages. Whose Pre-history? Whose antiquity? Whose Middle Ages? Whose modernity? Yusef Doucet presents African Cultural Historicity and invites us to challenge the one-sided monolithic state of the annals of history, but above all, to escape its trap.
