Probability is the backbone of science, but how well do you understand it? Odds are, not as well as you think; it is a surprisingly subtle concept that is often misunderstood, sometimes even by professionals who use it to guide crucial and far-reaching decisions. In this program, experts from technology, physics, medicine, and programming explore the slippery side of probability and the powerful role it plays in modern life.
This program is part of the Big Ideas Series, made possible with support from the John Templeton Foundation.
Original Program Date: May 30, 2015
Host: John Hockenberry

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.

Forget what you think you know about dark matter. After a 30-year search for a single, as yet unidentified, species of dark matter particle that would make up some 25% of the mass of the universe, physicists are starting to consider novel explanations. Some envision invisible matter hiding within the folds of extra spatial dimensions. Others suggest not one kind of dark matter particle, but numerous species inhabiting a shadow universe. Others still conjecture that dark matter doesn’t exist, and instead propose that the laws of gravity need modification. We’ll bring together leading thinkers on dark matter—the revolutionary and conventional alike—for a distinctly unconventional discussion on the dark universe.

An Invisible Threat: The Relationship Between Microwave Technology and Health | ENDEVR Documentary
We cannot see the waves, we cannot hear them, we cannot touch them, but they are all around us, invading the air, irradiating our body and the environment. An Invisible Threat looks at the relationship between microwave technology and health, investigating the conflicts of interest among industry representatives, politicians, scientists and consumers that leave us unprotected to the effects of radiation. Wireless networks irradiate microwaves indiscriminately across cities, villages and the countryside of all developed countries. This increasing exposure disturbs the biological processes that are essential for the healthy growth of human beings, animals and plants – it especially affects children and teenagers.
Our investigation delves into three groups: the telecommunications industry (mobile telephone companies, MMF); official organisations (WHO, IARC, ICNIRP) and official scientific reports (BioInitiative, Interphone, CEFALO).

ENDEVR explains the world we live in through high-class documentaries, special investigations, explainers videos and animations. We cover topics related to business, economics, geopolitics, social issues and everything in between that we think are interesting.
Black holes are gravitational behemoths that dramatically twist space and time. Recently, they’ve also pointed researchers to a remarkable proposal—that everything we see may be akin to a hologram. Alan Alda joins Kip Thorne, Robbert Dijkgraaf and other renowned researchers on an odyssey through one of nature’s most spectacular creations, and learn how they are leading scientists to rewrite the rules of reality.
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.
