Artificial Intelligence
Episode 34 of Redefining Reality
Trace the evolution of artificial intelligence (AI) from simple calculating machines to computers that can vanquish chess masters. Learn the distinction between weak AI, such as a chess-playing machine, and strong AI, which is a machine that has a truly…
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…
Jung and the Behaviorists
Episode 17 of Redefining Reality
Trace the different directions psychology took before World War II. Carl Jung extended Freud's ideas to encompass a universal collective unconscious. Meanwhile, the behaviorists rejected the mind to focus on observable behavior, an approach that had profound influence on advertising…
Chaos Theory
Episode 10 of Redefining Reality
Traditional attempts to understand the world assumed that it was regular, simple, periodic, and predictable. But nature surprised scientists, giving them a richer picture of reality through chaos theory, which includes fractal structures. Learn how chaos is not randomness but…
Quantum Consciousness
Episode 13 of Redefining Reality
Can physics explain consciousness? Start with Descartes, who held the dualistic view that the mind and body are separate, and see how materialists countered that brain processes produce the mind. Then discover what physics has to say about free will,…
The Birth of Sociology
Episode 22 of Redefining Reality
Culture imprints itself on our brains through the process of socialization. Investigate the insights that sociology provides--from the 19th-century founder of the discipline, Auguste Comte, to Herbert Spencer, Karl Marx, and Emile Durkheim, who suggested that crime has an unappreciated…
Genes and Identity
Episode 15 of Redefining Reality
The mechanism that drives evolution was not discovered until long after Darwin's death. Follow the clues that led researchers first to the cell nucleus, then to chromosomes and genes, and finally to the DNA molecule as the agent of heredity.…
Special Relativity
Episode 4 of Redefining Reality
Until 1905, physical reality consisted of absolute space, absolute time, and the luminiferous aether. Learn how Einstein's special theory of relativity overthrew this deeply ingrained view and heralded an entirely new conception of reality. Examine how cultural figures such as…
Transhumans: Making Living Gods
Episode 33 of Redefining Reality
Prosthetics, eyeglasses, and other aids were once seen as less-than-ideal substitutes for normal human abilities. But now technology can enhance us well beyond what's considered normal. Examine the superhuman traits currently available and those on the drawing board. Has the…
Race and Reality
Episode 24 of Redefining Reality
What differences between groups are real, and what differences are as arbitrary as a political boundary? Address this question regarding race, which less than a century ago was considered firmly rooted in biological reality. Trace the evidence that led this…
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…
Mathematics in Crisis
Episode 3 of Redefining Reality
The most secure science, mathematics, hit the rocks of uncertainty in the 19th and 20th centuries. Trace the shocking discoveries of non-Euclidean geometries, Cantor's paradoxes of infinite sets, and the incompleteness theorem of Kurt Godel. See how Alice in Wonderland…
The Rediscovery of the Mind
Episode 18 of Redefining Reality
The Holocaust raised troubling questions about the mind and its relation to authority. Examine three landmark experiments that tested the limits of human autonomy and came to shocking conclusions: Solomon Asch's group think study, Stanley Milgram's obedience study, and Philip…
Evolutionary Psychology
Episode 21 of Redefining Reality
If the human brain is the result of evolutionary processes, then many shared psychological traits must have adaptive advantages. Explore this intriguing view, known as evolutionary psychology. See how it can be illustrated by a simple logic problem, which perplexes…
Quantum Mechanics
Episode 8 of Redefining Reality
Delve into the paradoxical subject of quantum mechanics, which was pioneered by scientists probing atomic structure in the early 20th century. Learn about Max Planck, Niels Bohr, Werner Heisenberg, and Erwin Schrodinger. Focus on the Heisenberg uncertainty principle and the…
Defining Reality
Episode 2 of Redefining Reality
Take a step back to define reality as understood by the ancient Greeks. Then work your way forward through revolutionary ideas about reality proposed by Plato, Aristotle, Copernicus, Galileo, Kepler, and finally Newton, who inspired the Age of Enlightenment. Close…
Exoplanets and Extraterrestrial Life
Episode 28 of Redefining Reality
Fiction writers have led the way in exploring the prospects of life beyond Earth. See how scientists are catching up, looking for extraterrestrial organisms using a variety of ingenious techniques. Learn how they are narrowing the search and which tantalizing…
The Birth of Psychology
Episode 16 of Redefining Reality
The quest to understand human behavior inspired researchers to study the mind. Investigate the theories of Sigmund Freud, who gave the world a new vocabulary, including concepts like ego, id, and superego. Learn how Freud's legacy has been especially enduring…
Quantum Field Theory
Episode 9 of Redefining Reality
See how quantum field theory led to a stunning synthesis called the standard model of particle physics, which was confirmed by the 2012 discovery of the Higgs boson. Study the startling implications of this theory for our understanding of reality.…
Dark Matter and Dark Energy
Episode 11 of Redefining Reality
What happens when the accepted picture of reality is dramatically overthrown? Watch this happen in the late 20th century, when scientists suddenly discovered two completely unexpected phenomena: dark matter and dark energy, which together dwarf the contribution of ordinary matter…
