When no one is looking, a particle has near limitless potential: it can be nearly anywhere. But measure it, and the particle snaps to one position. How do subatomic objects shed their quantum weirdness? Experts in the field of physics, including David Z. Albert, Sean Carroll, Sheldon Goldstein, Ruediger Schack, and moderator Brian Greene, discuss the history of quantum mechanics, current theories in the field, and possibilities for the future.

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

Cosmology is the one field in which researchers can—literally—witness the past. The cosmic background radiation, ancient light streaming toward us since the Big Bang, provides a pristine window onto the birth and evolution of the universe. Already, the radiation has been key to confirming an early explosive expansion of space, determining the geometric shape of the universe and identifying seeds that resulted in galaxies. Now, the cosmic background radiation is poised to reveal when the first stars formed, what happened in the fraction of a second after the Big Bang, and the answers to a host of other bold questions about the cosmos. Join Nobel Laureate John Mather and other leading scientists who are leading the way.

The World Science Festival gathers great minds in science and the arts to produce live and digital content that allows a broad general audience to engage with scientific discoveries. Our mission is to cultivate a general public informed by science, inspired by its wonder, convinced of its value, and prepared to engage with its implications for the future.

Africa is a continent rich in natural resources with a young population. African nations in theory have the potential to transform their economies. But many of them are facing mountains of debt.

Africa’s external debt climbed to more than $650bn last year.

More than half of African countries are either in debt distress or teetering on the edge. But credit restructuring is painstakingly slow, and many governments end up spending more on servicing their debt than on healthcare or education.

The debt problem has plunged many nations into economic crisis with rising unemployment and poverty.

What if You STOP Eating Sugar for 30-Days?...Sugar is a socially accepted addiction that gets pacified as if it's an essential food group. I find it common to hear people brag about their sweet tooth, but sugar addiction should be categorized with other illicit drugs like cocaine and heroin. It's just as addictive and provides a slow excruciating gradual death.

In this video, you'll learn what happens when you don't eat sugar for 30 days. The benefits are so dramatic you probably won't believe it. But every time I issue this challenge to someone who is suffering from certain conditions the results are amazing.
