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.

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

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.

For decades, biologists have read and edited DNA, the code of life. Revolutionary developments are giving scientists the power to write it. Instead of tinkering with existing life forms, synthetic biologists may be on the verge of writing the DNA of a living organism from scratch. In the next decade, according to some, we may even see the first synthetic human genome. Join a distinguished group of synthetic biologists, geneticists and bioengineers who are edging closer to breathing life into matter.
