The search for, and ultimate discovery of, the Higgs boson is a triumph of modern physics—a global, half-century effort whose outcome would make or break the vaunted Standard Model of particle 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 in 2012 that physicists succeeded in creating and identifying this all-important new particle, the discovery was justly celebrated around the world.
episodes:
01. 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 us understand the “rules” for the universe.
02. 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 that eye-opening concept is essential to understanding the Higgs.
03. 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 existence of the Higgs years before we found it.
04. 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 Higgs – must exist.
05. 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 top quark.
06. Mass and Energy
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.”
07. 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 various forces between quarks and leptons.
08. 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.”
09. The Large Hadron Collider
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
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.
11. 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 matter and antimatter, and a Grand Unified Theory of particle physics.
12. Frontiers: Higgs in Space
The Standard Model explains the forces and molecules that comprise us and everything with which we interact. But even with the Higgs, we can’t explain the stuff that makes up 95% of the universe: dark matter and dark energy. In his conclusion, Professor Carroll shines a light on dark matter, its relationship with the Higgs, and the wonderful mysteries still ahead.
14. Visualizing Combinatorics: Art of Counting
Combinatorics deals with counting combinations of things. Discover that many such problems are really one problem: how many ways are there to arrange the letters in a word? Use this strategy and the factorial operation to make combinatorics questions a piece of cake.
