Patrick Winston's long-running MIT lecture on public speaking teaches heuristic rules for talks. It covers how to start, use time and place, boards, props and slides, and how to inform, persuade and finish.

The first lecture of MIT's 6.001 (SICP) with Abelson and Sussman, giving an overview of the course and an introduction to Lisp. It argues that computer science is about managing complexity and abstraction, not computers.

An 11-minute clip of Milton Friedman explaining the incentives of unions and how they affect employment. He argues unions restrict labor supply, raising pay for some workers while hurting low-skill workers.

Erik Demaine's MIT 6.006 lecture introducing dynamic programming through Fibonacci numbers and shortest paths. It covers memoization, subproblems and optimal substructure.

Milton Friedman explains why the US tax code is enormously complex and why meaningful reform is unlikely. He argues that politicians profit from the complexity, since tax breaks are products they sell and the code works as a tool of reward and punishment. The clip is about 14 minutes from his lecture series.

Erik Demaine's MIT 6.851 Advanced Data Structures lecture introducing succinct data structures, covering rank, select and tries. It is part of the Spring 2012 course.

The first lecture of Michael Sipser's MIT 18.404J Theory of Computation course, covering course mechanics, finite automata, regular languages and regular expressions. It proves closure of regular languages under union and begins concatenation.

The first lecture of MIT 6.042J Mathematics for Computer Science, taught by Tom Leighton, introducing mathematical proofs. It covers propositions, implication and basic proof methods.

A special lecture from MIT's Private Pilot Ground School in which Lt. Col. Randy Gordon, a fighter and test pilot, describes F-22 flight controls. Topics include thrust vectoring, the pilot command system and how software handles failures.

Lecture 7A from MIT 6.001 (SICP) by Abelson and Sussman introduces the metacircular evaluator, a Scheme interpreter written in Scheme. It shows how evaluating a program is itself a program.

Lecture 1B of MIT's 6.001 Structure and Interpretation of Computer Programs (1986) with Gerald Sussman, covering procedures, processes and the substitution model. It includes the line about the power of naming things.

A short clip of Milton Friedman explaining who benefits from occupational licensing requirements, arguing they mainly protect practitioners from competition.

Lecture 7A of the 1986 MIT 6.001 SICP course, with Gerald Sussman presenting the metacircular evaluator, part 1. It shows how a Lisp evaluator can be written in Lisp itself.

A short clip of Milton Friedman explaining his free-market view of monopoly, namely that monopolies persist mainly through government help. It is excerpted from the Milton Friedman Speaks series.

The first episode of Michael Sandel's Harvard course on moral reasoning, opening with the trolley problem and the choice between killing one to save five. Sandel draws out student arguments and introduces utilitarian and other approaches to justice.

Rick Hartley gives a roughly two-hour live training on proper grounding in PCB design. He explains how energy actually flows in the space between conductors, and how that governs noise, EMI, return paths and signal reflections.

James D'Angelo argues that the 1970 Legislative Reorganization Act made congressional votes public, opening the door to lobbyists and special interests. He proposes restoring secret voting as a cheap fix for corruption and many social ills.

A short excerpt from Dr Russell Barkley's 2012 Burnett Lecture on ADHD, focused on treatment. He argues ADHD is a disorder of executive function and self-regulation, and that environments should be designed to compensate.

A 2018 lecture, with subtitles available, by former Finnish intelligence colonel Martti J. Kari on Russian strategic culture. He walks through the historical layers of Russia and explains why the country behaves as it does.

Russian-American journalist Vladimir Pozner lectures at Yale on how US foreign policy toward Russia after the Soviet collapse shaped Putin, then takes audience questions on election interference, the Skripal poisoning and media independence.

Sean Carroll introduces his video series on the biggest ideas in physics, such as symmetry, space and matter, as informal discussions with follow-up Q&A videos. This is the short opening video of the series.

Donald Knuth's 2017 Christmas Tree Lecture at Stanford about a combinatorial geometry problem whose computed numbers matched a striking formula. He tells the story of the conjecture and its sequel.

The 1965 Cambridge Union debate between James Baldwin and William F. Buckley Jr. on whether the American Dream comes at the expense of the American Negro. It is a historic recording of the two speaking.

Neil Postman's 1997 lecture at College of DuPage, based on his book, argues that Americans treat technology as a national religion and depend on it to solve larger human problems. It includes audience questions.

The opening lecture of Steve Brunton's Control Bootcamp, covering the kinds of control and why closed-loop feedback matters. It starts a series that follows the control chapter of the Brunton and Kutz data-driven science book.

A professor from Illinois compares the cost of building, fueling and operating a nuclear plant against a natural gas plant, using visual charts. It shows how construction time and interest rates dominate, when the investment pays off and when costs cross over.
