Lecture · Royal Institution
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.

The Royal Institution · Various speakers
Thirty evening talks from the Royal Institution's lecture theatre in London, where Faraday once lectured: quantum fields, quantum biology, sensors, the quantum internet and the meaning of it all. Pick any one; each stands alone.

PBS Space Time
Goes beneath the slogans into the counting itself: how treating particles as truly identical changes the number of distinct arrangements, and how that produces the Fermi–Dirac and Bose–Einstein distributions you will meet in Part 3. Best watched after the lesson.

Serious Science
One of the three physicists who made the first atomic condensates in 1995 explains laser cooling and evaporative cooling in his own words. The perfect companion to Part 4.
Lecture · MIT
MIT OpenCourseWare · Barton Zwiebach
A twelve-minute segment of MIT's 8.06 in which Zwiebach takes up the symmetrization postulate, the formal rule behind this section: states of identical particles must be either symmetric or antisymmetric under exchange. The graduate-course statement of this section's 'only plus one or minus one', and a bridge to the two tribes of Part 2.
Short · Sheffield
Quantum Light University of Sheffield
A two-minute animation from a quantum-optics research group showing two indistinguishable single photons that reach a beam splitter at the same moment always leaving together. Watch it right after the paragraph on the 1987 Rochester experiment to see the Hong–Ou–Mandel dip happen.

Parth G
A beginner-friendly account of how quantum physics predicts two kinds of particle, bosons and fermions, and what those words actually mean. Watch it before this section's plus-or-minus sign in the two-particle wavefunction, which then shows why two fermions can never share a state.
Lecture · YouTube
DrPhysicsA
A patient, step-by-step introduction that sets Maxwell–Boltzmann, Fermi–Dirac and Bose–Einstein statistics side by side, then turns to the Fermi level. The start jumps to the Maxwell–Boltzmann chapter (15:29); Fermi–Dirac follows at 19:41, Bose–Einstein at 25:51 and the Fermi level at 30:16.
Lecture · MIT
MIT Video Productions · Wolfgang Ketterle
Ketterle, whose MIT group made the large sodium condensates in this section and who shared the 2001 Nobel Prize for them, tells the story of Bose–Einstein condensates in an hour-long Nobel Laureate Lecture at MIT. A far fuller account than the briefing's ten-minute Serious Science interview; watch it once the thermal-wavelength criterion makes sense.

minutephysics
Under two minutes on this section's central claim: a laser really works because of Bose–Einstein statistics, since photons are bosons. A quick primer before this section's Bose enhancement and the three ingredients of a laser.
