“The Fabric of the Cosmos,” a four-hour series based on the book by renowned physicist and author Brian Greene, takes us to the frontiers of physics to see how scientists are piecing together the most complete picture yet of space, time, and the universe. With each step, audiences will discover that just beneath the surface of our everyday experience lies a world we’d hardly recognize—a startling world far stranger and more wondrous than anyone expected.

Brian Greene is going to let you in on a secret: We’ve all been deceived. Our perceptions of time and space have led us astray. Much of what we thought we knew about our universe—that the past has already happened and the future is yet to be, that space is just an empty void, that our universe is the only universe that exists—just might be wrong.

Interweaving provocative theories, experiments, and stories with crystal-clear explanations and imaginative metaphors like those that defined the groundbreaking and highly acclaimed series “The Elegant Universe,” “The Fabric of the Cosmos” aims to be the most compelling, visual, and comprehensive picture of modern physics ever seen on television.

episodes:

01. What Is Space?

Space. It separates you from me, one galaxy from the next, and atoms from one another. It is everywhere in the universe. But to most of us, space is nothing, an empty void. Well, it turns out space is not what it seems. From the passenger seat of a New York cab driving near the speed of light, to a pool hall where billiard tables do fantastical things, Brian Greene reveals space as a dynamic fabric that can stretch, twist, warp, and ripple under the influence of gravity. Stranger still is a newly discovered ingredient of space that actually makes up 70 percent of the universe. Physicists call it dark energy, because while they know it’s out there, driving space to expand ever more quickly, they have no idea what it is.

Probing space on the smallest scales only makes the mysteries multiply. Down there, things are going on that physicists today can barely fathom—forces powerful enough to generate whole universes. To top it off, some of the strangest places in space, black holes, have led scientists to propose that like the hologram on your credit card, space may just be a projection of a deeper two-dimensional reality taking place on a distant surface that surrounds us. Space, far from being empty, is filled with some of the deepest mysteries of our time.

02. The Illusion of Time
Time. We waste it, save it, kill it, make it. The world runs on it. Yet ask physicists what time actually is, and the answer might shock you: They have no idea. Even more surprising, the deep sense we have of time passing from present to past may be nothing more than an illusion. How can our understanding of something so familiar be so wrong? In search of answers, Brian Greene takes us on the ultimate time-traveling adventure, hurtling 50 years into the future before stepping into a wormhole to travel back to the past. Along the way, he will reveal a new way of thinking about time in which moments past, present, and future—from the reign of T. rex to the birth of your great-great-grandchildren—exist all at once. This journey will bring us all the way back to the Big Bang, where physicists think the ultimate secrets of time may be hidden. You’ll never look at your wristwatch the same way again.

03. Quantum Leap

Join Brian Greene on a wild ride into the weird realm of quantum physics, which governs the universe on the tiniest of scales. Greene brings quantum mechanics to life in a nightclub like no other, where objects pop in and out of existence, and things over here can affect others over there, instantaneously and without anything crossing the space between them. A century ago, during the initial shots in the quantum revolution, the best minds of a generation—including Albert Einstein and Niels Bohr—squared off in a battle for the soul of physics. How could the rules of the quantum world, which work so well to describe the behavior of individual atoms and their components, conflict so dramatically with the everyday rules that govern people, planets, and galaxies?

Quantum mechanics may be counterintuitive, but it’s one of the most successful theories in the history of science, making predictions that have been confirmed to better than one part in a billion, while also launching the technological advances at the heart of modern life, like computers and cell phones. But even today, even with such profound successes, the debate still rages over what quantum mechanics implies for the true nature of reality.

Notes on the DVD: The DVD version of the program stated that one entangled photon is sent from the island of La Palma to the island of Tenerife by laser. The photon is sent via laser-guided telescope. In the DVD version of the program, it appears that the research team led by Anton Zeilinger has successfully teleported photons from La Palma to Tenerife. Although the Zeilinger team has used the method described to teleport photons shorter distances in other locations, as of November 2011, photons have not yet been teleported between La Palma andTenerife. The team plans to continue experiments in the Canary Islands, which attempt to complete the teleportation process there.

04. Universe or Multiverse?
Hard as it is to swallow, cutting-edge theories are suggesting that our universe may not be the only universe. Instead, it may be just one of an infinite number of universes that make up the “multiverse.” In this show, Brian Greene takes us on a tour of this brave new theory at the frontier of physics, showing what some of these alternate realities might be like. Some universes may be almost indistinguishable from our own; others may contain variations of all of us, where we exist but with different families, careers, and life stories. In still others, reality may be so radically different from ours as to be unrecognizable. Brian Greene reveals why this radical new picture of the cosmos is getting serious attention from scientists. It won’t be easy to prove, but if it’s right, our understanding of space, time, and our place in the universe will never be the same.

Series about the history of mathematics.

episodes:

01. The Language of the Universe

After showing how fundamental mathematics is to our lives, Marcus du Sautoy explores the mathematics of ancient Egypt, Mesopotamia and Greece.

In Egypt, he uncovers use of a decimal system based on ten fingers of the hand, while in former Mesopotamia he discovers that the way we tell the time today is based on the Babylonian Base 60 number system.

In Greece, he looks at the contributions of some of the giants of mathematics including Plato, Euclid, Archimedes and Pythagoras, who is credited with beginning the transformation of mathematics from a tool for counting into the analytical subject we know today.

02. The Genius of the East

When ancient Greece fell into decline, mathematical progress stagnated as Europe entered the Dark Ages, but in the East mathematics reached new heights.

Du Sautoy visits China and explores how maths helped build imperial China and was at the heart of such amazing feats of engineering as the Great Wall.

In India, he discovers how the symbol for the number zero was invented and Indian mathematicians’ understanding of the new concepts of infinity and negative numbers.

In the Middle East, he looks at the invention of the new language of algebra and the spread of Eastern knowledge to the West through mathematicians such as Leonardo Fibonacci, creator of the Fibonacci Sequence.

03. The Frontiers of Space

By the 17th century, Europe had taken over from the Middle East as the world’s powerhouse of mathematical ideas. Great strides had been made in understanding the geometry of objects fixed in time and space. The race was now on to discover the mathematics to describe objects in motion.

Marcus explores the work of René Descartes and Pierre Fermat, whose famous Last Theorem would puzzle mathematicians for more than 350 years. He also examines Isaac Newton’s development of the calculus, and goes in search of Leonard Euler, the father of topology or ‘bendy geometry’, and Carl Friedrich Gauss who, at the age of 24, was responsible for inventing a new way of handling equations – modular arithmetic.

04. To Infinity and Beyond

Marcus du Sautoy concludes his investigation into the history of mathematics with a look at some of the great unsolved problems that confronted mathematicians in the 20th century.

After exploring Georg Cantor’s work on infinity and Henri Poincare’s work on chaos theory, he looks at how mathematics was itself thrown into chaos by the discoveries of Kurt Godel, who showed that the unknowable is an integral part of maths, and Paul Cohen, who established that there were several different sorts of mathematics in which conflicting answers to the same question were possible.

He concludes his journey by considering the great unsolved problems of mathematics today, including the Riemann Hypothesis, a conjecture about the distribution of prime numbers. A million-dollar prize and a place in the history books await anyone who can prove Riemann’s theorem.
