About
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. In this 12-lecture masterpiece of scientific reporting, you'll learn how the discovery of the Higgs boson validates and deepens our understanding of the universe.

1. The Importance of the Higgs Boson
30m
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 us understand the "rules" for the universe.
2. Quantum Field Theory
30m
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 that eye-opening concept is essential to understanding the Higgs.
3. Atoms to Particles
30m
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 existence of the Higgs years before we found it.
4. The Power of Symmetry
30m
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 Higgs - must exist.
5. The Higgs Field
30m
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 top quark.
6. Mass and Energy
30m
In this lecture, "classical" physics, as explained by Newtonian and Einsteinian mechanics, provides insight into what makes the Higgs so special. Uncover the key to the Higgs's uniqueness in the particle zoo - that even at its minimum energy state (its "resting" state), the Higgs field has a large, constant value.
7. Colliding Particles
30m
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 various forces between quarks and leptons.
8. Particle Accelerators and Detectors
30m
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.
9. The Large Hadron Collider
30m
If blacksmithing were like particle physics, the Large Hadron Collider would be the anvil. Seventeen miles around and representing the unprecedented cooperation of scientists worldwide over the course of years, the LHC is a remarkable achievement. Explore its construction, capabilities, and amazing promise for the future of physics.
10. Capturing the Higgs Boson
30m
Looking for a needle in a haystack? Try looking for a never-before-seen particle in the largest machine ever built. With the LHC complete, the search for the Higgs began in earnest, and particle physics combined with probability to find the missing piece in the Standard Model puzzle. Professor Carroll describes both the exciting hunt and the key players in the amazing discovery.
