World Science Festival 05of12 Engineering the Brain Deploying a New Neural Toolkit
World Science Festival
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.

Part 1: Infinite Worlds A Journey through Parallel Universes
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.


Part 2: Quantum Reality Space Time and Entanglement
Ninety years after the historic double-slit experiment, the quantum revolution shows no sign of slowing. Join a vibrant conversation with renowned leaders in theoretical physics, quantum computation, and philosophical foundations, focused on how quantum physics continues to impact understanding on issues profound and practical, from the edge of black holes and the fibers of spacetime to teleportation and the future of computers.


Part 3: A Thin Sheet of Reality the Universe as a Hologram
What we touch. What we smell. What we feel. Theyre all part of our reality. But what if life as we know it reflects only one side of the full story? Some of the worlds leading physicists think that this may be the case. They believe that our reality is a projection-sort of like a hologram-of laws and processes that exist on a thin surface surrounding us at the edge of the universe.


Part 4: Beyond Beauty the Predictive Power of Symmetry
From a bees hexagonal honeycomb to the elliptical paths of planets, symmetry has long been recognized as a vital quality of nature. Einstein saw symmetry hidden in the fabric of space and time. The brilliant Emmy Noether proved that symmetry is the mathematical flower of deeply rooted physical law. And todays theorists are pursuing an even more exotic symmetry that, mathematically speaking, could be natures final fundamental symmetry: supersymmetry.


Part 5: Engineering the Brain Deploying a New Neural Toolkit
A new generation of technology is revolutionizing neuroscience, allowing a closer study of the brain than had ever seemed possible. The techniques are hybrids of optics, genetics, and synthetic biology with the ability to manipulate brain activity, often in real time. Through direct stimulation of neural connections, some of these techniques hold the promise for the treatment of diseases like depression or schizophrenia.


Part 6: Gravitational Waves a New Era of Astronomy Begins
On September 14th, 2015, a ripple in the fabric of space, created by the violent collision of two distant black holes over a billion years ago, washed across the Earth. As it did, two laser-based detectors, 50 years in the making – one in Louisiana and the other in Washington State – momentarily twitched, confirming a century-old prediction by Albert Einstein and marking the opening of a new era in astronomy. Join some of the very scientists responsible for this most anticipated discovery of our age and see how gravitational waves will be used to explore the universe like never before.


Part 7: Hidden Dimensions Exploring Hyperspace
Extra dimensions of space – the idea that we are immersed in hyperspace – may be key to explaining the fundamental nature of the universe. Relativity introduced time as the fourth dimension, and Einsteins subsequent work envisioned more dimensions still – but ultimately hit a dead end. Modern research has advanced the subject in ways he couldnt have imagined. John Hockenberry joins Brian Greene, Lawrence Krauss, and other leading thinkers on a visual tour through wondrous spatial realms that may lie beyond the ones we experience.


Part 8: Neutrinos Matter and Antimatter the Yin Yang of the Big Bang
What happened to all of the universe’s antimatter? Can a particle be its own anti-particle? And how do you build an experiment to find out? In this program, particle physicists reveal their hunt for a neutrino event so rare, it happens to a single atom at most once every 10,000,000,000,000,000,000,000,000 years: far longer than the current age of the universe. If they find it, it could explain no less than the existence of our matter-filled universe.


Part 9: How Music Affects Your Brain Notes on the Folds
Scientists are now finally discovering what thinkers, musicians, or even any of us with a Spotify account and a set of headphones could have told you on instinct: music lights up multiple corners of the brain, strengthening our neural networks, firing up memory and emotion, and showing us what it means to be human. In fact, music is as essential to being human as language and may even predate it. Can music also repair broken networks, restore memory, and strengthen the brain?


Part 10: Measure for Measure Quantum Physics and Reality
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.


Part 11: The Illusion of Certainty Risk Probability and Chance
Stuff happens. The weather forecast says its sunny, but you just got drenched. You got a flu shot-but youre sick in bed with the flu. Your best friend from Boston met your other best friend from San Francisco. Coincidentally. What are the odds? Risk, probability, chance, coincidence-they play a significant role in the way we make decisions about health, education, relationships, and money. But where does this data come from and what does it really mean?


Part 12: The Matter of Antimatter Answering the Cosmic Riddle of Existence
You exist. You shouldnt. Stars and galaxies and planets exist. They shouldnt. The nascent universe contained equal parts matter and antimatter that should have instantly obliterated each other, turning the Big Bang into the Big Fizzle. And yet, here we are: flesh, blood, stars, moons, sky. Why? Come join us as we dive deep down the rabbit hole of solving the mystery of the missing antimatter.
