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.

J Richard Gott leads a journey through the history of our understanding of the Universe’s structure, and explains the ‘cosmic web’: the idea that our Universe is like a sponge made up of clusters of galaxies intricately connected by filaments of galaxies.

J. Richard Gott's book "The Cosmic Web: Mysterious Architecture of the Universe" is available for purchase now - https://geni.us/EtIx

J Richard Gott was among the first cosmologists to propose that the structure of our Universe is like a sponge made up of clusters of galaxies intricately connected by filaments of galaxies – a magnificent structure now called the 'cosmic web'. In this talk he shows how ambitious telescope surveys such as the Sloan Digital Sky Survey are transforming our understanding of the cosmos, and how the cosmic web holds vital clues to the origins of the universe and the next trillion years that lie ahead.

J Richard Gott is Emeritus Professor of Astrophysical Sciences at Princeton University and is noted for his contributions to cosmology and general relativity.

When epidemiologists are faced with addressing questions that are too difficult, expensive or dangerous to test in the real world, they turn to mathematical modeling. Hear how scientists from the Institute for Disease Modeling are using models to guide global efforts towards the eradication and control of infectious diseases.

The nation’s wealth is not stolen by politicians but civil servants - Sen Urhoghide

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.

Agroforestry presents lots of opportunities for the organic grower: to grow new fruit and nut crops to sell; to produce wood and wood chip to use; to provide shelter and reduce flooding; and to provide habitat for other creatures.

In this webinar, we hear from experienced growers about the practical considerations, opportunities and pitfalls of agroforestry in organic horticulture.

Ben Raskin is head of horticulture and agroforestry at the Soil Association, a director of the Organic Growers Alliance, and an experienced grower who is currently establishing an agroforestry system at Eastbrook farm in Wiltshire.

John Tucker is director of woodland outreach at the Woodland Trust. John talks us through how to get started in agroforestry and what you should consider when deciding how to incorporate trees, from analysing your site and exploring your objectives, through to choosing species and getting trees in the ground.

Andy Dibben is head grower at Abbey Home Farm in Cirencester. He joins us to talk us through his experience of incorporating trees into the site and to share his learning and advice.

This webinar is a partnership between the CSA Network UK, the Seed Sovereignty Programme run by the Gaia Foundation, the Landworkers’ Alliance, and the Organic Growers Alliance and forms part of a webinar series funded by Farming the Future. Recorded on 24 February 2021.

You need a farmer at least 3 times a day. Find out how one farmer is maximising on this and spending in a month what he earns in a week. Also how various indigenous vegetable varieties are continually improving in economic value.
