Lecture · Rutgers University
Rutgers Graduate-Undergrad Seminar in Math-Phys · Tim Maudlin
The philosopher whose 1995 trilemma organizes this whole chapter explains, in a talk for Rutgers' online seminar in mathematical physics, what the measurement problem is and what a solution would have to do. Sort every solution he considers by which of the three claims in Part 2 it gives up.
Lecture · University of Washington
UW Video · Sean Carroll
A public lecture by one of the best-known advocates of many worlds, starting at the chapter marker for the Everett interpretation (30:40); the many-worlds chapter begins at 39:56 and the 'too many universes' worry at 44:18. Earlier chapters cover Copenhagen (21:32), Schrödinger's cat (23:18) and the Heisenberg cut (25:54) if you want a review of Parts 1–3.
Lecture · Aarhus University
Aarhus Universitet · Angelo Bassi
"Precision tests of models of spontaneous wave function collapse", a 2023 colloquium by one of the authors of the 2020 Gran Sasso search described in Part 6. It treats collapse models as what they are, rival theories that experiments can rule out; listen for which kinds of experiment constrain the collapse rate and how.
Lecture · Caltech
John Preskill · 2021
The lecture from Caltech Ph/CS 219A Quantum Computation (John Preskill, 2021) that goes with Chapter 22. The whole course is in the Lecture Hall.
Course · Stanford
Stanford · Leonard Susskind · 2006
Nine evenings on the strangest resource in physics — spin, density matrices, entangled states and Bell's theorem — taught by Susskind to a room of non-specialists. Pairs naturally with Unit 5.
Course · Caltech
John Preskill · 2021
The graduate course from the physicist who coined the terms "quantum supremacy" and "NISQ": density operators, measurement, channels, Bell inequalities, teleportation, circuits, Shor's factoring, Grover's search and quantum simulation. Advanced, and worth every minute.
Lecture · Royal Institution
The Royal Institution · Jim Al-Khalili · 2025
A Friday Evening Discourse recorded at the Ri in November 2025, a century after Heisenberg's breakthrough: a hundred years of quantum theory, from the 1920s pioneers to the technologies being built now. Keep asking which claims are experiment and which are interpretation.
Lecture · Royal Institution
The Royal Institution · Sean Carroll · 2020
Sean Carroll tells the story from Planck and Einstein through Bohr, de Broglie and Schrödinger, then argues that the measurement problem is still open and makes his case for the many-worlds interpretation. Notice where the history ends and his interpretation begins.
Lecture · Nobel Prize
Nobel Prize · Serge Haroche & David J. Wineland · 2012
Serge Haroche on trapping photons in a box to watch the quantum-to-classical boundary — decoherence — in action, then David Wineland on superposition and entanglement with trapped ions. The experiments that turned thought experiments into laboratory routine.

Dominic Walliman's illustrated tour of the main interpretations of quantum mechanics and the measurement problem they are trying to solve. As you watch, note how each view answers two questions: is the wavefunction real, and does it ever collapse? Today we sort the same views by which of three claims they give up, then add the physics of decoherence.
