Brian Greene and Alan Alda Discuss Why Einstein Hated Quantum Mechanics
 
15:14
Albert Einstein was not a fan of quantum mechanics. He was annoyed by the uncertain, random nature of the universe it implied (hence the famous quote "God does not play dice with the universe"). So, Einstein tried to develop a unified theory that would circumvent what he saw as quantum mechanics' flaws. In this excerpt from the 2014 World Science Festival Program Dear Albert, Alan Alda and Brian Greene discuss Einstein's relationship with the "unruly child" of quantum mechanics, and how the famed physicist came up with the Special Theory of Relativity.

What is the Holographic Principle?
 
03:00
When Stephen Hawking elegantly described the relationship of quantum mechanics with black holes, he inadvertently opened the door to a radical possibility: that our universe, as we know it, is like a hologram. Science historian Peter Galison and leading physicists Brian Greene and Cumrun Vafa explain how the resilient nature of information combined with the behavior of event horizons suggests that the three dimensions of reality we observe may in fact be a two-dimensional information structure "painted" on some sort of cosmological horizon.

Leonard Susskind Takes On Hawking Radiation
 
04:58
Stephen Hawking's premise was sound; his math irrefutable. As matter falls into a black hole, quantum events cause it to emit particles. These particles—what became known as Hawking Radiation—lead to the eventual evaporation of the black hole, and any information about the matter that fell in would be lost forever. But for physicists Leonard Susskind and Gerard ’t Hooft, something didn't sit right. In fact, it seemed to go against the very laws of physics—a contradiction which ultimately led to the radical possibility of the knowable universe as encoded information. They discuss with moderator John Hockenberry the delicate challenges of arguing with a man whose theories were for all intents and purposes "unassailable."

Ever wanted to understand Einstein’s theories of relativity, but didn’t know where to start? Let Brian Greene introduce you to you the Theory of General Relativity with an alluring metaphor. Physicist Brian Greene explains how Albert Einstein, wrestling with how exactly gravity works, originally formulated the general theory of relativity. The landmark breakthrough provided the first unified description of gravity as a geometric property of space and time. It also laid the foundation for understanding more bizarre properties of the universe—like the curvature of spacetime, string theory, and the possibility of multiple, hidden dimensions of the universe.

Physicist Janet Conrad explains the phenomena of Cherenkov light, the eerie blue glow often associated with nuclear reactors. Cherenkov light is emitted when charged particles travelling through a medium move faster than light—which has been slowed by the same medium. It is similar to the sonic boom that follows an aircraft that is moving faster than the speed of sound. Scientists can use Cherenkov light to detect neutrinos moving through giant tanks of water.

The behavior of dark matter, by nearly all accounts, is exceedingly odd: It influences the movement of so-called normal matter through gravity, but refuses to interact via any of the other known forces.

The Black Hole Mystery That Keeps Physicist Raphael Bousso Up At Night
 
02:01
Einstein's General Relativity established that there would be no physical effect marking the location of the black hole's edge. Recent results have pitted this nearly century old scientific thought against the basic equations of quantum mechanics, with some suggesting that black holes are actually surrounded by firewalls that would instantly incinerate any cosmological explorer. Hear Raphael Bousso's struggle with the "Firewall Paradox."

Can We Reach Absolute Zero?
 
01:43
Absolute zero is the temperature at which entropy reaches its minimum value, and all energy has been taken out of a system. But is it reachable? Can anything ever be that cold? Nobel Prize-winning physicist William Phillips explains the daunting—possibly impossible—task of reaching the coldest temperature known.

Synthetic Biology and the Future of Creation
 
03:18
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.

Mathematics: Invented or Discovered?
 
03:10
Mario Livio discusses the complementary processes of mathematical invention and discovery. While we invent some mathematical concepts—such as prime and imaginary numbers—by deciding how to define them, these concepts can lead to a plethora of mathematical discoveries.

What will we learn from the detection of gravitational waves?
 
01:49
Today's discovery of gravitational waves is a landmark in physics history. It confirms predictions Einstein made over 100 years ago. But what other kinds of answers can this discovery bring? Gabriela González, spokesperson for the LIGO scientific collaboration, gives a brief insight into the implications this achievement has for the future of science.

The Moth: Confessions of a Pro-Social Psychopath - James Fallon
 
15:23
Neuroscientist James Fallon is a self-styled "hobbit scientist." The rules are simple: Don't talk to the press and don't go out of your area of expertise. But when a fascinating new brain scanner enters the lab, Fallon can't resist. He ends up breaking both rules, and learns a lot more about himself than he bargained for. Scientists, writers, and artists take to the stage to tell stories about their personal relationship to science. The result is a collection of poignant, hilarious and unpredictable tales sure to intrigue and surely hard to forget. Presented in collaboration with The Moth. Watch them all in The Moth at WSF Series.

The Unreasonable Effectiveness of Mathematics
 
04:36
Basic researchers working in pure mathematics often develop fundamental laws, even entire branches of math, without any specific application in mind. Yet, as Mario Livio points out here, many of these posited laws turn out—sometimes centuries later—to perfectly describe the behavior of the real world with remarkable precision. This phenomenon was best articulated in the early 1900s by the Hungarian physicist Eugene Wigner as the "unreasonable effectiveness of mathematics." And it begs the question: What gives mathematics this power? Cognitive scientist Marvin Minsky provides an interesting, if wry, answer: if it were not the case, there would be no one to notice.

How do you detect dark matter?
 
04:18
Forget finding a needle in a haystack. Scientists hunting for dark matter are faced with the task of detecting a substance made of an unknown material that might not even exist. At the 2016 World Science Festival program Shaking Up the Dark Universe, cosmologist Katherine Freese discussed the progress scientists are making on this sometimes maddening search.
