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.
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 a previously unimagined complexity within the universe.
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.
Grand Unified Theories
Episode 12 of Redefining Reality
Since its earliest days, science has been on a mission to unite disparate phenomena under the umbrella of more comprehensive theories. Follow the search for a grand unified theory (GUT) that unifies the workings of quantum forces, and a theory of everything (TOE) that quantizes gravity. One current TOE candidate…
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 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 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, and probe the famous thought experiment involving Schrodinger's cat.
The Electric Field
On of the most important ideas in physics is the field, which maps the presence and magnitude of a force at different points in space. Explore the concept of the electric field, and learn how Gauss's law describes the field lines emerging from an enclosed charge.
The Higgs Field
With the basics of particle physics covered, Professor Carroll walks us through the decades-long hunt for the Higgs. You'll meet the many brilliant minds--Anderson, Englert, and Higgs among them--who determinedly set out to solve the mystery of the weak nuclear field. You'll also discover why Angelina Jolie is like a…
A New Theory of Matter
Episode 3 of The Nature of Matter
Discover how the idea that light comes in discrete packets called "quanta" led to a startling new theory of matter: quantum mechanics. One prediction is that matter, like light, behaves as both a particle and a wave, a property observed in subatomic particles such as electrons.
