Rated 5 out of 5 by from Sean Carroll once again shining In my opinion, Prof Carroll is the foremost physic educator around today. He explains the subject in a logical, methodical, cheery way. His passion for physics is infectious, and he strikes the right balance between simplicity and more advanced concepts. Finally starting to feel like I have an understanding of the Higgs mechanism.

Rated 2 out of 5 by from Pre-existing knowledge crucial The lecturer is pleasant to listen to and some examples are very well presented. However, if you do not have a significant knowledge of physics already, you will struggle. Too many things don't get explained enough or at all. New things get introduced very late in the course (lecture 10 out of 12) but not explained. All in all, not good.

Rated 3 out of 5 by from Somewhat Disappointing Professor Carroll has done yeoman’s work in dealing with this most difficult subject, but without addressing the underlying mathematics, any explanations of particle physics, quantum field theory and symmetry reduce to elaborate arm-waving. It might have been better if Lecture 2 (Quantum Field Theory) had been fleshed out with a more thorough presentation of Laplace’s gravitational field model, then adding a glimpse of the Einstein field equations as a quick mention of general relativity. After all, the Higgs field is the star of the show in this very well delivered lecture series. HWF, Mesa, AZ.

Rated 5 out of 5 by from The Higgs Boson and Beyond Science has always called to me to try to understand it; it is a very knowable subject if you put in the effort and build a broad base. This lecture series adds to my base and helps me grow. Professor Sean Carroll has a terrific way of delivering this information and backs up his topic with clever analogies and examples. I’m sure I’ll return to this series several times as I flesh out my base of scientific knowledge.

Rated 5 out of 5 by from Is the Standard Model of particle physics complete I always enjoy Sean Carroll's courses and lectures. He is a great teacher. So, I was not disappointed with this course on the Higgs Boson. It was a wonderful overview. I noticed that the other reviewers had only only one general disappointment with the course: they feel that they were not sufficiently motivated as to why we needed the Higgs boson in the Standard Model. That is my only criticism, too. I understand why, but then I am a particle physicist, but it wouldn't have hurt for Prof. Carroll to have included a few more words at the beginning to motivate the listener why the Higgs is so important, and even that once having found it, the Standard Model is still not complete. Perhaps, he could have asked in the introduction, if all existence can be described by one field or another and their influence can be felt by other particles, the Standard Model particles have no real physical extent in space, so exactly what is "mass" then? Anyway, Prof. Carroll did a great job with the subject overall.

Rated 5 out of 5 by from Great course! I've sat through MANY post-school presentations/lectures, both remotely, and in-person. Dr. Carroll is a VERY engaging presenter, his lectures are entertaining, and the professional graphics keep your attention. (Think about presenters that droned on-and-on, thinking they're witty, with a hand-scribbled whiteboard as their only supportive information.) I thought this would be a "lay-person's" level of the Higgs. I planned on browsing the web, while Dr. Carroll's first several lectures inched through basic Physics. I was wrong. Dr. Carroll gave an Executive Summary in Lecture #1, in keeping with peer presentations, then proceeded to have background and supporting lectures, follow on. I had to put my computer down, in order to pay attention. This doesn't mean this course is only for intermediate/advanced Physics people! I've seen several comments about how laypeople were left behind. I'm sorry to see that. His approach seems to be well-suited for all disciplines. I'm going to reply on several of their threads. "The Great Courses Plus" courses have several benefits: 1) The ability to pause/rewind the lecture; 2) A "Course Guidebook" that has materials that can be referenced in later discussions (Re: "Particle Zoo"); 3) I've got an "intermediate" understanding of Physics, but I still needed to close my computer, and pay attention to Dr. Carroll's presentation. (Trust me, this is new to me. I used to ignore ANY professor's first several lectures. Unfortunately, this correlates to my overall GPA...).

Rated 5 out of 5 by from Challenging Ideas, Well Presented I'd heard/read about the Higgs particle and wanted to know more about it. I viewed this course from a double perspective: 1) as a curious learner with a background in physical chemistry dating back to the 1960's, and 2) as a (retired) teacher of high-school chemistry and physics. As a curious learner, Prof. Carroll's lectures provided far more than I had expected. He provides a step-by-step overview of the ideas needed to assemble an understanding of what the Higgs is about, including quantum fields, symmetry, and the standard model of elementary particles. I especially appreciate that he describes the experiments and the equipment that led to our present knowledge. As a retired teacher, I wonder who would benefit from this course. I think you have to have some background in these ideas in order to follow the presentation. I don't think my average high school students would understand the course. So would I recommend it to someone who never studied physical science beyond high school level? It depends. If you're looking for a general sense of how much knowledge and experience went into the discovery of the Higgs, yes, enjoy. But I think it helps to be comfortable reading graphs and thinking in terms of intangibles. By the way, the lectures are very well supported by graphics and other visual effects. Prof. Carroll is an excellent teacher, but it helps if you are somewhat prepared through introductory studies.

Rated 5 out of 5 by from Finally someone who actually is a teacher and not Finally someone who actually is a teacher and not a storyteller. Too often this kind of courses is just a retelling of the discoveries, and in the case of quantum physics most often making a big deal about how strange something is. In some cases I even noticed that they even make the mistake he is describing in the course regarding relativistic mass and mass. In this course his focus is instead on trying to teach and explain. Which is what all courses in science actually should be about, but my guess is that most "storytellers" doesn't really know what they talk about and therefore can't explain it. The subject is very complex and the level is advanced, which means a lot of rewatching and contemplating. But I don't think that there is any need for prior knowledge other than a basic understanding that most people have. That said, the course isn't for everyone and if you don't want to put in any effort of your own this is not for you.

The Importance of the Higgs Boson

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.

Quantum Field Theory

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.

32 min
Atoms to Particles

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.

31 min
The Power of Symmetry

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.

31 min
The Higgs Field

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.

33 min
Mass and Energy

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.

31 min
Colliding Particles

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.

31 min
Particle Accelerators and Detectors

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.

32 min
The Large Hadron Collider

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.

32 min
Capturing the Higgs Boson

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.

31 min
Beyond the Standard Model of Particle Physics

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.

Frontiers-Higgs in Space

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.
