History's Mysteries
Episode 1 of The Inexplicable Universe
Begin this journey by taking a closer look at concepts that were once unexplainable but are now better understood. You'll focus on two such former mysteries: the existence of an invisible "aether" through which light and sound were believed to…
The Spooky Universe
Episode 2 of The Inexplicable Universe
Did you know that electrons have never actually been observed by scientists to this day? Or that quarks can only be studied in pairs? Or that as you travel faster or find yourself in a higher gravity, time ticks more…
Inexplicable Physics
Episode 4 of The Inexplicable Universe
Turn now to some inexplicable aspects of physics and our physical world. Among the many eye-opening topics you'll learn about in this episode are the discovery of more and more elements on the periodic table; muon neutrinos, tao particles, and…
Inexplicable Life
Episode 3 of The Inexplicable Universe
Join Professor Tyson on a fascinating investigation of the possible origins of life in the universe. Why was Jupiter believed to be a good environment for life in the 17th century? Why is there only one single "tree of life"…
Why Time Is a Mystery
Episode 1 of Mysteries of Modern Physics: Time Series
Begin your study of the physics of time with these questions: What is a clock? What does it mean to say that "time passes"? What is the "arrow of time"? Then look at the concept of entropy and how it…
The Transformability of Information
Episode 1 of The Science of Information
What is information? Explore the surprising answer of American mathematician Claude Shannon, who concluded that information is the ability to distinguish reliably among possible alternatives. Consider why this idea was so revolutionary, and see how it led to the concept…
Silicon Run I
Part of the Series: Silicon Run Series
Silicon Run I uses live industrial footage to show the many processes necessary to manufacture microchips, including crystal growth, circuit design, and the wafer fabrication process for CMOS technology. Using close-ups of manufacturing processes and device animation, Silicon Run I…
Inexplicable Cosmology
Episode 6 of The Inexplicable Universe
Brace yourself for a fascinating trip through dimensions higher than our own. You'll discover how quantum physics and string theory have opened our eyes to the possibilities of quantum foam, the multiverse, and antimatter. Join Professor Tyson for a preview…
Catching the Sun
Through the stories of workers and entrepreneurs in the U.S. and China, Catching the Sun captures the global race to lead the clean energy future. Over the course of a solar jobs training program, Catching the Sun follows the hope…
Time Travel, Tunneling, Tennis, and Tea
Part of the Series: Einstein's Relativity and the Quantum Revolution
What are the two big ideas of modern physics? How can nonscientists gain a handle on these ideas and the radical changes they bring to our philosophical thinking about the physical world?
Inexplicable Space
Episode 5 of The Inexplicable Universe
Shoot off into the stars for an investigation of some perplexing aspects of space that science has uncovered in the last half-century. Learn about the mysterious trajectory of the Pioneer spacecraft (known as the "Pioneer anomaly"). Explore two of the…
I Dream of Wires - The Machine that Shaped Electronic Music
I Dream of Wires is a documentary about the rise, fall and rebirth of the machine that shaped electronic music: the modular synthesizer. The film explores the synthesizer's remarkable history, revealing how innovators like Robert Moog, working at Columbia University's…
Metaphysics and the Nature of Science
Episode 1 of Redefining Reality
Start with the metaphysical concept of reality and how it led to a scientific worldview. Then see how the scientific picture of reality changes as theories are refined or overthrown. Explore examples such as the germ theory of disease and…
MEMS: Making Micro Machines
MEMS: Making Micro Machines is an overview of the manufacture and design of microelectromechanical systems. This video shows the fabrication, testing and packaging, and design of some of our most common MEMS devices. It features the fabrication of Hewlett-Packard's thermal…
Computation and Logic Gates
Episode 2 of The Science of Information
Accompany the young Claude Shannon to the Massachusetts Institute of Technology, where in 1937 he submitted a master's thesis proving that Boolean algebra could be used to simplify the unwieldy analog computing devices of the day. Drawing on Shannon's ideas,…
What Is Time?
Episode 2 of Mysteries of Modern Physics: Time Series
Approach time from a philosophical perspective. "Presentism" holds that the past and future are not real; only the present moment is real. However, the laws of physics appear to support "eternalism"--the view that all of the moments in the history…
Energy and Human Civilization
Episode 1 of The Science of Energy
How much energy is required to power human civilization? What is it that makes our cities, factories, homes, and cars so energy inefficient? How can the average individual affect energy directions? Find out in this overview of how energy touches…
Trusses: The Power of the Triangle
Episode 7 of Understanding the World's Greatest Structures
Trusses, the subject of this fascinating episode, are rigid frameworks composed of structural members connected at joints and arranged into networks of triangles. Learn how they work to stabilize and support a range of structural wonders, including the Brooklyn Bridge…
Data Analytics
Episode 36 of Redefining Reality
Today's networked culture is a dream come true for researchers in fields from marketing to sociology to epidemiology. Learn how big data puts potentially everyone and everything under the microscope of analysis, creating a comprehensive view of the intricate reality…
The Importance of the Higgs Boson
Episode 1 of The Higgs Boson and Beyond Course
Why was the discovery of the Higgs boson such a big deal? That's the key question that Professor Carroll tackles in his illuminating introduction. Take a fascinating dive into the world of modern particle physics and see how the Higgs…
