The Particle Zoo
Are quarks, the particles that make up protons and neutrons, the truly elementary particles? What are the three fundamental forces that physicists identify as holding particles together? Are they manifestations of a single, universal force?
The Higgs Boson and Beyond Course
The discovery of the Higgs boson is a triumph of modern physics. The hunt for the Higgs was the subject of wide media attention due to the cost of the project, the complexity of the experiment, and the importance of its result. And, when it was announced with great fanfare…
Atoms to Particles
Now that you know what particles really are, it's time to walk through the "particle zoo" and explore the roles of photons, gluons, and quarks. Along the way, Professor Carroll looks back on the development of the Standard Model and how our changing understanding of the weak nuclear field suggested…
The Particle Zoo
By 1960 a myriad of seeming elementary particles had been discovered. Survey the standard model that restored order to this subatomic chaos, describing a universe whose fundamental particles include six quarks; the electron and two heavier cousins; elusive neutrinos; and force-carrying particles such as the photon.
The Importance of the Higgs Boson
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 is the missing piece of a scientific puzzle that helps…
Beyond the Standard Model of Particle Physics
Now that the Higgs boson has been found, everything is answered, right? Not quite. Professor Carroll says the properties of the Higgs suggest that something else is at work out there. Moreover, the Higgs boson can be a stepping-stone to our exploration of dark matter, extra dimensions, the asymmetry of…
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…
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.
Wave or Particle?
In the 1920s physicists established that light and matter display both wave- and particle-like behavior. Probe the nature of this apparent contradiction and the meaning of Werner Heisenberg's famous uncertainty principle, which introduces a fundamental indeterminacy into physics.
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…
Wave or Particle?
Einstein's resolution of the photoelectric effect problem suggests that light consists of particles (photons). But how can this be reconciled with the understanding of light as an electromagnetic wave?
The Power of Symmetry
Symmetries don't only apply to geometrical objects. They apply to the laws of physics themselves. In this lecture, you may feel your mind twist in asymmetrical ways as you explore how symmetry governs the known forces of nature and how it helped form a wild theory that an as-yet-undiscovered particle--the…
