    The Standard Model of Particle Physics: A Triumph of Science

    Quanta Magazine

    Cambridge physicist David Tong assembles the Standard Model piece by piece, starting from fields and ending with the questions it cannot answer, which is exactly the arc of this session. Watch for how each new force appears as a new field, and note the channel's own correction: at 13:50 the animation leaves the photon out of the force carriers, but the narration has it right.

    The Black Hole Information Paradox

    PBS Space Time

    Matt O'Dowd sets out why Hawking radiation seems to destroy information and why that collides with quantum mechanics. It dates from 2018, so pair it with Part 6, which brings the story up to the 2019 Page-curve calculations.

    Quantum Field Theory visualized

    ScienceClic English

    An animated tour that starts from the question behind this section, how to reconcile relativity with quantum mechanics, and pictures particles as excitations of fields that fill space. It also asks what spin is and where electric charge comes from, questions that return with Dirac's equation in Part 2 and the Standard Model in Part 4.

    How To Read Feynman Diagrams

    Domain of Science

    A short, friendly guide to reading Feynman diagrams, the picture language of this section. Pair it with the second paragraph, then remember the section's honesty clause: internal lines label terms in a calculation, not particles a detector could ever register.

    THE HARDEST Problem in Physics Explained Intuitively: Quantum Gravity

    Arvin Ash

    The start jumps to the chapter 'Why can't we quantize gravity?' (7:56), the breakdown this section's first paragraph describes; the next chapter, 'Ways that we could quantize gravity' (11:19), leads into the paragraphs on strings and loops.

    Nima Arkani-Hamed Public Lecture: Quantum Mechanics and Spacetime in the 21st Century

    Perimeter Institute for Theoretical Physics · Nima Arkani-Hamed · 2014

    One of the most original theorists working today on why quantum mechanics and gravity together suggest that spacetime itself may not be fundamental. Delivered at Perimeter Institute in November 2014; demanding in places, exhilarating throughout.

    Quantum Fields: The Real Building Blocks of the Universe - with David Tong

    The Royal Institution · David Tong · 2017

    Cambridge's David Tong explains why the fundamental ingredients of the universe are fields, not particles, and how a handful of quantum fields in the Standard Model produce everything you can see. The perfect overture to Chapter 25.

    How ALPHA-g creates and drops antihydrogen atoms

    CERN

    CERN's own three-and-a-half-minute 3D animation of ALPHA-g: antihydrogen made from positrons and antiprotons inside the ALPHA atom trap, then dropped to see which way it falls. It shows the machinery behind the 2023 result that closes this section.

    Demystifying the Higgs Boson with Leonard Susskind

    Stanford · Leonard Susskind

    Recorded on 30 July 2012, less than four weeks after the ATLAS and CMS announcement, Susskind explains what the Higgs mechanism is and what 'giving mass' to a particle actually means. The long-form companion to the third paragraph of this section; a notepad helps.

    Peter Higgs, Nobel Prize in Physics 2013: Five questions

    Nobel Prize · Peter Higgs

    Peter Higgs himself in the Nobel Prize's 'Five questions' interview: the start jumps to 1:18, where he is asked to describe his work in simple terms. Hear the 1964 idea from one of the physicists who had it, then stay for the remaining questions.
