Course Overview

This two-part series explains, in easily accessible terms, the discovery of the infinitely small particles-the quarks and neutrinos, muons and bosons-that make up everything in nature, from microbes to stars.

It covers the nature and functions of the individual particles, and their roles in the Standard Model of particle physics (a theory that is as much a masterpiece in science as Shakespeare's works are in literature). The lectures also trace the history of particle physics as a science, and the dedicated scientists and complex technology that have made this branch of physics so profoundly productive and important.

This course provides a framework to understand such cutting-edge physics research as gravity waves, dark matter, and string theory.

  • 1
    Nature of Physics
    What is the world made of, how do the constituents fit, and what are the fundamental rules they obey? We discuss the history of human understanding of atoms and subatoms, and articulate some primary ideas in particle physics, focusing on what we know well. x
  • 2
    Standard Model of Particle Physics
    Where do we stand in our understanding of the smallest building blocks of the world? The Standard Model of particle physics is one of the greatest quantitative success stories in science. What are the players, what are the forces, and what are some of the concepts and buzzwords? x
  • 3
    Pre-History of Particle Physics
    We summarize the scientific evolution of atomism: prescientific ideas, the classical worldview of Isaac Newton, and finally the modern ideas of fundamental constituents. How could a famous physicist say physics was "done" in 1899? x
  • 4
    Birth of Modern Physics
    We explore the transition from 19th-century classical physics to 20th-century modern physics. This is the story of Planck, Rutherford, Einstein, and the early quantum physicists. We gain our primitive first understandings of the realistic structure of atoms. x
  • 5
    Quantum Mechanics Gets Serious
    A qualitative introduction to the work of Schrödinger, Heisenberg, and Dirac in describing electrons, this lecture looks at how the first fundamental particle was discovered. We introduce such concepts as spin and quantum electrodynamics (QED), and conclude with the experimental discovery of antimatter and the neutron. x
  • 6
    New Particles & New Technologies
    This lecture conducts a survey of particle physics in the first half of the 20th century: cosmic rays, the discovery of the muon (Who ordered that?), Yukawa's theory of nuclear force, and the discovery of the pion. We conclude by discussing the electron volt (ev) as a tool to make sense of the particle discoveries to come. x
  • 7
    Weak Interactions & the Neutrino
    What is a weak interaction, and how is it connected to radioactivity? What is an interaction, anyway, and how does it differ from a force? We discuss the carriers of weak forces, W and Z particles, and introduce neutrinos—ghostlike particles with no mass. x
  • 8
    Accelerators & Particle Explosion
    Particle accelerators, born after World War II, were in some respects the origin of big science in the United States. We discuss how these machines worked and the steady stream of new particles discovered through their use. x
  • 9
    Particle "Zoo"
    Some new particles exhibited a curious mix of strong and weak properties. The proper description of these "strange particles" was crucial in understanding the particle "zoo." This lecture introduces lots of new lingo—mesons and baryons, hadrons and leptons, bosons and fermions. x
  • 10
    Fields & Forces
    This lecture covers the concept of a field and the early problems involved in constructing the modern theory of quantum electrodynamics (QED). We examine the 1947 Shelter Island conference, the problem of infinities, the concept of renormalization, and Feynman diagrams. x
  • 11
    "Three Quarks for Muster Mark"
    Hadrons (strongly interacting particles) are fundamental but not elementary. Could they be made of something else? This is the breakthrough idea of quarks. This lecture explores early quark conditions. x
  • 12
    From Quarks to QCD
    If quarks are the fundamental particles, how do they interact? The answer: They carry a new charge, a strong charge described by color. We introduce these concepts as part of the fledgling theory of quantum chromodynamics (QCD) from the 1970s. x
  • 13
    Symmetry & Conservation Laws
    What does symmetry mean to a physicist? Pretty much what it means to you: an aesthetic property of a system, a pattern that appears the same when viewed from different perspectives. x
  • 14
    Broken Symmetry, Shattered Mirrors
    Symmetry is sometimes slightly broken or badly broken. Either way, there is something useful to be learned about the world. This lecture explores (a seemingly obvious) mirror symmetry, also called parity, and the stunning surprise that it is not perfect (parity violation). x
  • 15
    November Revolution of 1974
    In November of 1974, two simultaneous experimental discoveries rocked the world of particle physics. A new particle, a new quark, had been found. The charmed quark changed the scientific paradigm for physicists overnight. x
  • 16
    A New Generation
    The last great surprises: a new generation of particles. The tau lepton is discovered, and symmetry arguments tell scientists that the tau neutrino, and bottom and top quarks, have to be there ... and they are! x
  • 17
    Weak Forces & the Standard Model
    Progress in the 1960s and '70s was not limited to strong forces and quarks. This is the story of the theory of Weinberg, Salam, and Glashow—the electroweak theory—that unified the fundamental weak, electric, and magnetic forces. We can now summarize the Standard Model. x
  • 18
    Greatest Success Story in Physics
    The Standard Model of particle physics is an impressive accomplishment. Its unparalleled success includes qualitative and quantitative measurements, with years of increasingly precise tests. x
  • 19
    The Higgs Particle
    The Higgs particle is the least understood piece of our story so far, and the one central part not yet directly verified. What is this particle, and what role does it play in the Standard Model? x
  • 20
    Solar Neutrino Puzzle
    We have always assumed that neutrinos are massless, but what if they did have mass? Why are there far fewer neutrinos coming from the sun than there should be? What does it mean to talk about neutrinos changing flavor? x
  • 21
    Back to the Future (1)—Experiments to Come
    The SSC may be dead, but experimental particle physics is alive and vibrant! What are some of the burning issues? Among those we will discuss are the search for violations of matter-antimatter symmetry, and neutrino beams that will travel through the Earth from source to target. x
  • 22
    Back to the Future (2)—Puzzles & Progress
    The Standard Model is a great success. So why are many physicists looking for a more fundamental theory of nature? We'll begin with the missing link of gravity; issues of simplicity, unification, and grand unification; then two developments that to many physicists seem to be the best candidates for new physics: supersymmetry and string theory. x
  • 23
    Really Big Stuff—The Origin of the Universe
    What does cosmology, the study of the universe as a whole, have to do with particle physics? Matter at the very largest scales requires understanding of matter at the very tiniest. We'll discuss how particle physics fits in with the Big Bang, the more recent theory of inflation, and the newly discovered dark matter and dark energy. x
  • 24
    Looking Back & Looking Forward
    What have we learned after more than 100 years of intense study of fundamental particles? What puzzles remain? What you might take out of this course is a sense of physical order and understanding of the constituents of the larger world. x

Particle Physics for Non-Physicists: A Tour of the Microcosmos is rated 4.6 out of 5 by 118.
Rated 5 out of 5 by from Excellent Explanations I have watched this course twice now. I took notes the second time and I am going to watch it a third time. Steven Pollock is an excellent lecturer for the non physicist. I enjoyed his enthusiasm.
Date published: 2018-03-03
Rated 5 out of 5 by from Great Information I have been listening to this as soon as I received it. I have several of Prof. Polock's other courses, and like his style. His pace is just right, and he seems to have a real passion for the subject. My only complaint is that the multi-CD set arrived with the discs intact, but the interior mounts and CD holders were broken. So, the CDs slide around in the package. I was told that the case could not be replaced, and that I would have to return everything.

Rated 5 out of 5 by from Don't Miss It! I'm surprised I hadn't already written a review of this course. I've watched it through twice now; once on my own and a second time with a friend who was interested. This is presenting what some consider the greatest intellectual achievement of mankind to date: the evolution of the "standard model" of particle physics, to laymen who may not be able to work with mathematics beyond multiplication, division and the meaning of logarithms. Yes, he does show some equations at times for those who have the interest and ability to understand them--but if you find them confusing or distracting just don't worry about the equations. Dr. Pollock does an excellent job of describing the basic ideas behind the equations in plain English. This is a rare feat; it's pretty much a tour de force. The subject matter is rich, complex, multi-faceted. There are areas in which it still seems incomplete and there are competing ideas of where to go next. Dr. Pollock manages somehow to describe all of this and to make it fascinating. I've gone through several dozen Great Courses and I would say this is, in my opinion, probably one of the two best and most important ones I've ever listened to. For anyone who has enough interest to even be looking at the course description--get it and watch it! Preferably at least get the video and the course outline. If possible get the full transcript too, because there may be some occasions where you want to refer back to it in print and not have to search for the specific issue via the video. There are a few advances since this was produced: yes, CERN confirmed the existence of the Higgs boson, which was still presumed when Dr. Pollock gave his lectures; yes they've found a few other exotic particles but so far, nothing that really breaks the "standard model". Until the next really major advance, and who knows how far away that may be--this is still a wonderful and topical presentation of fundamental science.

Rated 5 out of 5 by from Looking forward to learning this. While I have not even started this course yet, I am so looking forward to the right time for me to do so. I know in advance this will be worthwhile as it is taught by a really excellent physics professor. (I am still in the process of learning Classical Physics as presented by Professor Pollock.) My interest in physics stems from when I was a child and I have never lost the desire to really learn it even though I am now in my 60's.

Rated 5 out of 5 by from Now I understand the vocabulary This course reveals how much physics "knowledge" has changed since I was in college in the 1970's. I quickly realized that unless I had additional tools for reference, "the words" of the Professor would just sound like static in my ears and I would be LOST. Therefore, to better understand the lectures and cement the information in my mind, I printed out a CURRENT format of the Standard Model of Particle Physics. Including the Higgs Boson which was only theorized at the time of this course. (That would be a recommendation for updating this course) The Higgs is sitting outside the regular Boson boundary with a Mass at about 125GeV , With Charge Zero and Spin Zero which sets it apart from ALL of the other elementary "particles". Sitting with a copy of THAT ONE sheet with the Hadrons, Leptons, Gauge Bosons and the Higgs (along with some Feynman Diagrams) I was able to follow the lectures, and quite often predict the direction in which Professor Pollock was to take us. Especially when the concepts of QED (Quantum Electrodynamics) and QCD (Quantum Chromodynamics) were introduced. I was startled to realize that so much of The Standard Model (when I was in college) lacked any firm discovery, much less the determination of mass, charge and spin of the particles. Physics was NOT my college major. ( I wish I were young enough to GO BACK and become immersed in the subject for a purpose other than my own enlightenment) To follow Professor Pollock, you need to listen to him, BUT ALSO follow along on the Standard Model to make any sense of "the unique vocabulary" much less the relationships and reactions at the sub-atomic world. This course along with my reference sheets and diagrams collectively became a Rosetta Stone for interpretation.

Rated 4 out of 5 by from Opens up new thought processes This is an excellent course for someone who has some basic physics knowledge but hasn't studied physics for 25+ years. The first lessons are great for anyone, but later in the course, the instructor moves further into more complex issues. Anyone, however, will gain new insights and perspectives whether or not they have taken a physics course. My only reservation is that-- had I known the course date-- I might have moved directly to the Higgs Boson and Beyond course. Particle Physics for Non-Physicists was produced when the Higgs particle was just a "maybe."
Date published: 2017-12-01
Rated 5 out of 5 by from Life changing This course is absolutely fascinating. I am going to have to give it another listen through. I cannot imagine the beauty of the closed form if the instruction is this wonderful. When Max Tegmark said we were all great theoreticians for any inference off the CMD, he was not kidding. This series adds even more from the micro to the macro. I am left with such a happy furrow on my brow pretending like I can contemplate how a point like electrons and positrons come out of the Dirac formalism, yet from the unity of string theory are not as such. From Weinberg to Glashow and the eletroweak, to the decoupling of the early universe of all potential combinations (if we are to take QED as dogma and not just the super exiting) this series leaves its audience captivated and contemplating. If the Z boson prediction is not clairvoyance, what is? Physics is complete, so long as we are willing to bring it to it. At the least, clarity rings true here.

Rated 4 out of 5 by from good review of Particle physics Review of Particle Physics by Steven Pollock # 1247 Over all good review of Particle physics – look at the chapter summaries to see the major topics. He is enthusiastic, & seems well versed on most topics. It is worth the time to watch, but you should have some background in the subject You should already know about quarks, leptons, field forces, etc. He speaks a little too fast, but speech is clear. The last chapter is good review & thots to consider in future study. The lectures were made in 2003, so now in 2017, it is a little behind. E.g. he mentions work is being done searching for the Higgs particle, - was found in 2016, etc. Needs more & better graphics. He has a strange habit of moving up & down, sort of “bouncing” – did get used to it later on. Left out some good stories, like the work by the Bell Labs men: Pensius & Wilson who detected the Cosmic Background radiation. How they tried to eliminate all possible reasons, even scraping the pigeon droppings in the big bell receiver. His views are strict reductionist, ignores possible other related topics like emergence, synchronous behavior, complexity, etc. Would help if he covered how scatter diagrams are captured & deciphered. Overall good course. 4 star.
