Wangari Maathai was the founder of the Green Belt Movement and the 2004 Nobel Peace Prize Laureate. She was born in Nyeri, a rural area of Kenya. Professor Maathai was internationally acknowledged for her struggle for democracy, human rights, and environmental conservation, and served on the board of many organisations. She addressed the UN on a number of occasions and spoke on behalf of women at special sessions of the General
Assembly during the five-year review of the Earth Summit. In recognition of her deep commitment to the environment, the United Nations (UN) Secretary-General named her a UN Messenger of Peace in December 2009, with a focus on the environment and climate change.

After ten years of fighting, peace between the Tuareg guerrillas and government troops was recently signed. The war and the crisis of modernity have endangered the secular caravan carrying salt on camels from the Aïr to Agadez. This year, two Tuareg children can accompany their families in this trailer for the first time in a climate of peace, and this chapter of the series will see the generational change of the Tuareg tradition thanks to the friendship of these two children whose families were on opposite sides during the past conflict.

Mathematical mysteries have challenged humanity’s most powerful thinkers and inspired passionate, lifelong obsessions in search of answers. From the strangeness of prime numbers and the nature of infinity, to the turbulent flow of fluids and the geometry of hyperspace, mathematics is our most potent tool for revealing immutable truths. The event was a vibrant tour to the boundaries of the mathematical universe, and explore the deep puzzles that have been solved, the masterminds who powered the breakthroughs, and the towering challenges that have shaken the confidence of some of today’s most accomplished mathematicians—even as they enlist new ways to pursue mathematical truths.

This program is part of the Big Ideas Series, made possible with support from the John Templeton Foundation.
