Wizards of Odds: The Power of Probability | 2015
Wizards of Odds: The Power of Probability | 2015 Ambakisye-Okang Dukuzumurenyi 18 Views • 5 years ago

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
Participants: Robert Green, Leonard Mlodinow, Masoud Mohseni, Alan Peters

Loose Ends: String Theory and the Quest for the Ultimate Theory | 2019
Loose Ends: String Theory and the Quest for the Ultimate Theory | 2019 Ambakisye-Okang Dukuzumurenyi 18 Views • 5 years ago

Thirty-five years ago string theory took physics by storm, promising the coveted unified theory of nature’s forces that Einstein valiantly sought but never found. In the intervening decades, string theory has brought a collection of mind-boggling possibilities into the lexicon of mainstream thinking—extra dimensions of space, holographic worlds, and multiple universes. Some researchers view these developments as symptoms of string theory having lost its way. Others argue that string theory, although very much still a work in progress, is revealing stunning new qualities of reality. Join leading minds in theoretical physics for a whirlwind ride through the twists and turns of string theory—its past, its future, and what it tells us about the search for the universe’s final theory.

PARTICIPANTS: Marcelo Gleiser, Michael Dine, Andrew Strominger

Infinite Worlds: A Journey through Parallel Universes | 2015
Infinite Worlds: A Journey through Parallel Universes | 2015 Ambakisye-Okang Dukuzumurenyi 18 Views • 5 years ago

The multiverse hypothesis, suggesting that our universe is but one of perhaps infinitely many, speaks to the very nature of reality. Join physicist Brian Greene, cosmologists Alan Guth and Andrei Linde, and philosopher Nick Bostrom as they discuss and debate this controversial implication of forefront research and explore its potential for redefining the cosmic order. Moderated by Robert Krulwich and featuring an original musical interlude, inspired by parallel worlds, by DJ Spooky.

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

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.

Slaves in Italy? | DW Documentary
Slaves in Italy? | DW Documentary Ambakisye-Okang Dukuzumurenyi 18 Views • 5 years ago

Yvan Sagnet from Cameroon is battling modern slavery in Italy's agricultural sector. Sagnet once worked as a low-wage farmhand. Now he is fighting for the rights of seasonal farmworkers, taking criminal recruiters, or gangmasters, to court.

Yvan Sagnet calls them slaves: the hundreds of thousands of seasonal farmworkers from Africa and eastern Europe on Italy's fields. Without their labor the country would have no tomato, orange or olive harvest. But the workers are exploited and often forced to live under inhumane conditions in ruins or shanty towns called ghettos. In 2011 Sagnet himself briefly picked tomatoes on the fields near the southern Italian town of Nardò. For four days he labored to fill the 350-kilogram crates. He earned 14 euros a day, ten of which he had to hand over to the gangmaster, or Caporale, for transport and water. Caporale is the term for the criminal recruiters who control and exploit the workers. After a 14-hour day working under the blazing sun and even being beaten, Sagnet took home only four euros. He helped to organize the first strike among the farmhands. It was a success, and since then he has been an activist for the rights of the farmworkers and against the gangmasters. Despite death threats, he has set up an organization called NoCap, a label to certify produce farmed under ethically acceptable conditions. And he has taken his fight against exploitation and slavery to the courts. So far, the Italian justice system has responded slowly. It's a fight that will take a long time to win.
