All Creatures Great and Smart
Brian Hare, Vanessa Woods, Jeremy Niven, Patrick R. Hof, Klaus Zuberbühler, Jad Abumrad
Join a panel of leading scientists whose research is challenging long-held assumptions about the differences between “animal” and “human”—and learn about pin-sized brains that can count, categorize, and hold a grudge against those who’ve tried to swat them.
Beautiful Minds: The Enigma of Genius
Philip Glass, Julie Taymor, Rex Jung, Douglas Fields, Dean Keith Simonton, Brian Greene
Immanuel Kant, who coined the term genius in the 1700s, defined it as the rare capacity to independently understand concepts that would normally have to be taught by another person. Since then, the spectrum of abilities that we call genius has widened, but pivotal questions remain: What exactly is genius?
Consciousness: Explored and Explained
Charlie Kaufman, Giulio Tononi, Alan Alda
Consciousness is a terrible curse. Or is it? Filmmaker Charlie Kaufman, neuroscientist Giulio Tononi, and moderator Alan Alda explore and explain the art, science, and mystery of consciousness.
Eye Candy: Science, Sight, Art
Jules Feiffer, Buzz Hays, Patrick Cavanagh, Margaret S. Livingstone, Christopher W. Tyler, Lawrence Weschler
There may be universal biological principles that drive art’s appeal, and its capacity to engage our brains and our interest.
Keeping Secrets: Cryptography in a Connected World
Josh Zepps, Brian Snow, Tal Rabin, Orr Dunkelman, Simon Singh
Since the earliest days of communication, clever minds have devised methods for enciphering messages to shield them from prying eyes.
Man-Made Minds: Living with Thinking Machines
Faith Salie, David Ferrucci, Eric Horvitz, Hod Lipson, Rodney Brooks
Who, or what, are these thinking machines? We were joined by IBM’s WATSON, the computer Jeopardy! champion, along with leading roboticists and computer scientists, to explore the thinking machines of today and the possibilities to come in the not-too-distant future.
Mind and Machine: The Future of Thinking
John Donoghue, Gary Small, Luciano Floridi, Rosalind Picard, John Hockenberry
As thinking, remembering, and innovating become increasingly interwoven with technological advances, what are we capable of?
Mysteries of the Mathematical Universe
Keith Devlin, Jonathan Borwein, Robert Krulwich, Marcus du Sautoy, Simon Singh
Mathematical mysteries have challenged humanity’s most powerful thinkers and inspired passionate, lifelong obsessions in search of answers.
Notes & Neurons: In Search of the Common Chorus
Jamshed Bharucha, Bobby McFerrin, Daniel Levitin, Lawrence Parsons, John Schaefer
Is our response to music hard-wired or culturally determined? Is the reaction to rhythm and melody universal or influenced by environment?
Strangers in the Mirror
Oliver Sacks, Chuck Close, Alexandra Lynch, Robert Krulwich
What’s it like to face a faceless world? Acclaimed neurologist Oliver Sacks and portraitist Chuck Close share their experiences of living with a curious condition known as “face blindness.”
The Illusion of Certainty: Risk, Probability, and Chance
Marcus du Sautoy, Gerd Gigerenzer, Leonard Mlodinow, Josh Tenenbaum, Amir Aczel
Stuff happens. The weather forecast says it’s sunny, but you just got drenched. You got a flu shot—but you’re sick in bed with the flu. Your best friend from Boston met your other best friend from San Francisco. Coincidentally. What are the odds?
The Limits of Understanding
Mario Livio, Gregory Chaitin, Rebecca Newberger Goldstein, Marvin Minsky, Sir Paul Nurse
This statement is false. Think about it, and it makes your head hurt. If it’s true, it’s false. If it’s false, it’s true. Leading thinkers untangle Kurt Gödel's landmark paradox and explore the wider implications of the early 19th-century logician's revolutionary findings.
The Mathemagician
Arthur Benjamin
Discover the man who's faster than a calculator.
The Mind after Midnight: Where Do You Go When You Go to Sleep?
Carl Zimmer, Matthew Wilson, Niels Rattenborg, Carlos H. Schenck
We spend a third of our lives asleep. Every organism on Earth—from rats to dolphins to fruit flies to microorganisms—relies on sleep for its survival, yet science is still wrestling with a fundamental question: Why does sleep exist?
The Origins of Orientation: Sexuality in 2011
Jim Pfaus, Marc Breedlove, Meredith Chivers, Paul Vasey, Andrew Solomon
What is the relationship between sexuality and gender? How do biology and culture interact to produce it? Why does homosexuality defy evolution’s dictate for reproduction?
The Unbearable Lightness of Memory
Dan Harris, Daniel L. Schacter, Elizabeth Phelps, Lynn Nadel, Todd Sacktor
It’s the thought of your childhood home. It’s that comforting aroma you can still smell ten years later. It’s the way you define yourself. It’s your memory.

A Thin Sheet of Reality: The Universe as a Hologram
John Hockenberry, Gerard ’t Hooft, Leonard Susskind, Herman Verlinde, Raphael Bousso
What we touch. What we smell. What we feel. They’re all part of our reality. But what if life as we know it reflects only one side of the full story? Some of the world’s leading physicists think that this may be the case.
Astronaut Diary: Life in Space
Tracy Caldwell Dyson, Sandra Magnus, Leland Melvin, Dava Newman, Miles O’Brien
Hear firsthand from the world’s most intrepid explorers about what it’s like to soar upward and leave our home, planet Earth, behind.
Astronomy’s New Messengers
Laura Danly, Andrea Lommen, Kip Thorne, Rainer Weiss
Einstein's 1916 General Theory of Relativity predicted the existence of gravitational waves—undulations in the very fabric of space and time. It's taken nearly a century, but researchers at the Laser Interferometer Gravitational-wave Observatory are now finally poised to detect them.
Back to the Big Bang: Inside the Large Hadron Collider
Frank Wilczek, Jennifer Klay, Marcela Carena, Monica Dunford, John Hockenberry

Black Holes and Holographic Worlds
Alan Alda, Raphael Bousso, Robbert Dijkgraaf, Andrew Hamilton, Kip Thorne
Black holes are gravitational behemoths that can twist space and time. Recently, they’ve also pointed researchers to a remarkable proposal—that everything we see may be akin to a hologram.
Hidden Dimensions: Exploring Hyperspace
Brian Greene, Linda Dalrymple Henderson, Shamit Kachru, Lawrence M. Krauss, John Hockenberry, Escher String Quartet
Extra dimensions of space—the idea that we are immersed in hyperspace—may be key to explaining the fundamental nature of the universe.
Infinite Worlds: A Journey through Parallel Universes
Brian Greene, Nick Bostrom, Alan Guth, Andrei Linde, Paul D. Miller, Robert Krulwich
The multiverse hypothesis, suggesting that our universe is but one of perhaps infinitely many, speaks to the very nature of reality.
On The Shoulders of Giants: A Special Address by Steven Weinberg
Steven Weinberg
In a new annual series, World Science Festival audiences are invited to stand on the shoulders of modern-day giants. In “The Future of Big Science,” Nobel laureate and physicist Steven Weinberg considers the future of fundamental physics.
Rebooting the Cosmos: Is the Universe the Ultimate Computer?
John Hockenberry, Edward Fredkin, Seth Lloyd, Fotini Markopoulou-Kalamara, Jürgen Schmidhuber
As computers become progressively faster and more powerful, they’ve gained the impressive capacity to simulate increasingly realistic environments. Might life and the world as we know it be a simulation on a super advanced computer?
The Search for Life in the Universe
Jill Tarter, Steven Squyres, David Charbonneau, Michael Russell, Sir Paul Nurse
Are we alone? It’s a question that has obsessed us for centuries, and now we have the technology to do more than wonder.

!@#$% Traffic: From Insects to Interstates
Robert Krulwich, Iain Couzin, Anna Nagurney, Mitchell Joachim
Can marching ants, schooling fish, and herding wildebeests teach us something about the morning commute?
