"The infinite! No other question has ever moved so profoundly the spirit of man," said David Hilbert, one of the most influential mathematicians of the 19th century. A subject extensively studied by philosophers, mathematicians, and more recently, physicists and cosmologists, infinity still stands as an enigma of the intellectual world. Thinkers clash over questions such as: Does infinity exist? Can it be found in the physical world? What types of infinity are there? Through an interdisciplinary discussion with some of the world's leading thinkers, this program will delve into the many facets of infinity and address some of the deepest questions and controversies that mention of the infinite continues to inspire.
This program is part of the Big Ideas Series, made possible with support from the John Templeton Foundation.

In recent years, machines have grown increasingly capable of listening, communicating, and learning—transforming the way they collaborate with us, and significantly impacting our economy, health, and daily routines. Who, or what, are these thinking machines? As we teach them to become more sophisticated, how will they complement our lives? What will separate their ways of thinking from ours? And what happens when these machines understand data, concepts, and behaviors too big or impenetrable for humans to grasp? We were joined by IBM’s WATSON, the computer Jeopardy! champion, along with leading roboticists and computer scientists, to explore the thinking machines of today and the possibilities to come in the not-too-distant future.

What does it take to build a future in Africa on our own terms?
In this Webnation Africa podcast, a University of Ghana professor shares his perspective on Black history, cultural identity, education, economic ownership and repatriation. Drawing on his experience living in Ghana, he discusses why he believes the way we learn history affects the choices we make today—from where we spend our money to how we build communities.
We also explore the history of the transatlantic slave trade, the meaning of returning to Ghana, and a difficult question: can political freedom last without economic independence?
This is a conversation with a range of historical interpretations and personal views. We invite you to listen critically and share where you agree, disagree, or want to learn more.
In this episode: African history and the transatlantic slave trade • Ghana and repatriation • Education and cultural identity • Black owned businesses • Economic independence • Building community in Africa
