Introducing the Quantum
Begin your study of the ideas that revolutionized physics at the atomic scale: quantum theory. The word quantum comes from Max Planck's proposal in 1900 that the atomic vibrations that produce light must be quantized: that is, they occur only with certain discrete energies.
Time in Quantum Mechanics
Quantum mechanics is the most precise theory ever invented, yet it leads to startling interpretations of the nature of reality. Probe a quantum state called the collapse of the wave function that may underlie the arrow of time. Are the indications that it shows irreversibility real or only illusory?
Quantum Mechanics
In 1926 Erwin Schrodinger developed an equation that underlies much of our modern quantum-mechanical description of physical reality. Solve a simple problem with the Schrodinger equation. Then learn how the merger of quantum mechanics and special relativity led to the discovery of antimatter.
Quantum Field Theory
Toss out the textbook image of electrons circling an atom's nucleus. This lecture explores the big twist of quantum field theory: The world isn't really made of particles. They're fascinating and necessary figments of quantum mechanics created by observing the fields that fill every inch of the universe, and grasping…
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 strange behavior of the Schrodinger wave function.
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. Close by examining its impact on the visual arts.
Mind, Body, and Questions of Consciousness
Episode 1 of Mind-Body Philosophy
The 3.5 pounds of gray matter in your skull processes all the information you need to live and thrive - from the functioning of your physical body to your relationships with loved ones. But how can the physical matter of the brain create the subjective experience of your life? That…
Mind and Body in Greek Philosophy
Episode 2 of Mind-Body Philosophy
Humans have been asking this question for thousands of years: exactly how are we related to the world around us? Learn what modern Western thought inherited from the Greeks and how the theories of Pythagoras, Socrates, Plato, and Aristotle still affect our thinking and questioning today.
Eastern Perspectives on Mind and Body
Episode 3 of Mind-Body Philosophy
Western philosophers want to understand how the physical brain produces the reality of subjective experience. But Hindu and Buddhist traditions don't recognize that same dualism. Unlike the Western attempt to discover the truth of how things are, Eastern philosophy takes a more practical line of inquiry, examining how to best…
Using the Body to Shape the Mind
Episode 4 of Mind-Body Philosophy
We tend to think of the mind being in charge of, and giving instructions to, the body. But is it possible for the body to direct the mind? Learn how the Eastern practical disciplines of yoga and meditation and Western habits of physical exercise can affect the brain and the…
History of the Soul
Episode 5 of Mind-Body Philosophy
While the concept of the soul has been of great philosophical importance over the millennia, it is not addressed by contemporary brain science or philosophy of the mind. Learn why William James encouraged people to believe in the soul if they wanted to, but "exiled" the subject from the concerns…
How Descartes Divided Mental from Physical
Episode 6 of Mind-Body Philosophy
How can you know with absolute certainty that you exist? Rene Descartes famously answered: "I think; therefore I am." He also suggested a complete split between the mind and the physical body. The vast and sharply divided responses to Descartes' dualism still influence the ways in which we address the…
