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."

What if your brain at 77 were as plastic as it was at 7? What if you could learn Mandarin with the ease of a toddler or play Rachmaninoff without breaking a sweat? A growing understanding of neuroplasticity suggests these fantasies could one day become reality. Neuroplasticity may also be the key to solving diseases like Alzheimer’s, depression, and autism. In this program, leading neuroscientists discuss their most recent findings and both the tantalizing possibilities and pitfalls for our future cognitive selves.

PARTICIPANTS: Alvaro Pascual-Leone, Nim Tottenham, Carla Shatz

MODERATOR: Guy McKhann

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.

The contributions of Black women in science throughout history is highly underrepresented and not adequately taught in schools. Host Dr. Eleanor Seaton sits down with Dr. Sheretta Butler-Barnes to discuss her initiative to promote a curriculum that inspires young Black girls to pursue an education and career in STEM.

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.

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
