Time Reversal in Particle Physics
Explore advances in physics since Newton's time that reveal exceptions to the rule that interactions between moving particles are fully reversible. Could irreversible reactions between elementary particles explain the arrow of time? Weigh the evidence for and against this view.
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.
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.
Particle Accelerators and Detectors
Want to build your own particle accelerator? You'll need a lot of money, a lot of room, and the information that Professor Carroll shares in this lecture. You'll learn that particle accelerators aren't simply "atom smashers." They bring into existence new particles that weren't there before.
Systems of Particles
How do you analyze a complex system in motion? One special point in the system, called the center of mass, reduces the problem to its simplest form. Also learn how a system's momentum is unchanged unless external forces act on it. Then apply the conservation of momentum principle to analyze…
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…
Colliding Particles
Once physicists established the need for the Higgs boson to exist, how did they set out to locate it? It was just a matter of bringing the particles and fields together under the right conditions. You'll see how physicists use Feynman diagrams to keep track of how virtual particles carry…
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…
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?
Particle or Wave?
In 1923, Louis de Broglie proposed that, like light photons, particles of matter might also display wave properties. The wave nature of smaller particles such as electrons is quite visible and leads to many unusual phenomena, including quantum tunneling mentioned in Lecture 1.
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?
