Veritasium explains how jet engines run hotter than their components' melting points, using cooling air and single-crystal superalloy turbine blades. It covers how the blades are grown as aligned crystals.

Glenn Vanderburg argues at the O'Reilly Software Architecture Conference that software development is an engineering discipline, even if immature. He contends the discredited body of knowledge called software engineering has led people to wrongly reject the label.

A Linear engineer talks about scaling the company's sync engine, which keeps client data local and synchronized. It follows an earlier talk on the same system.

Scott Manley explains rotating detonation engines, how they differ from pulsed detonation engines, and why thermodynamics predicts they beat traditional jet and rocket engines.

Hillel Wayne reports on interviews with 17 people who have worked as both software and traditional engineers. He argues the fields are fundamentally the same and have much to learn from each other.

Episode 7 of the Inside Koenigsegg series, where Christian von Koenigsegg demonstrates the camless Free Valve engine technology. It discusses how such innovation could affect the wider auto industry.

A Tom Scott guest video by Grady Hillhouse of Practical Engineering on the 1981 Hyatt Regency walkway collapse. A seemingly minor change to the support design led to catastrophic failure, which is why the case is taught as a lesson to check and double-check everything.

A driver films a police DUI checkpoint on the 4th of July where a drug dog alerts on his car and he is searched without consent, though he broke no laws. He is released without charges after officers learn he was recording.

A short test firing of the XRS-2200 linear aerospike engine at NASA Stennis Space Center, which was designed for the cancelled X-33 VentureStar. The engine is shown at roughly 80 percent of max thrust.

A Ryan George comedy sketch about the experience of using Google search in 2022, where results are full of ads, spam and Reddit and Amazon detours.

A short comedic complaint by ProZD about YouTube search failing to surface his own video even when searching its exact title. It illustrates how poor search results have become.

Engineering Explained examines Toyota's hydrogen-burning V8 engine built with Yamaha and explains the practical problems of hydrogen combustion vehicles. It covers efficiency, storage and distribution issues.

Richard Hamming's 1995 recording of his talk 'You and Your Research', drawn from his graduate engineering course. He discusses how great scientists pick important problems and build careers, drawing on his years at Bell Labs.

The final lecture of Richard Hamming's Learning to Learn course, from 1995, based on his well-known talk 'You and Your Research'. It covers how to do important work and build a career.

Kurzgesagt explains stellar engines such as the Shkadov thruster and Caplan thruster, which could move the Sun and solar system across the galaxy over millions of years to avoid hazards and reach new regions.

The introductory lecture of Richard Hamming's capstone course, The Art of Doing Science and Engineering: Learning to Learn. It focuses on style of thinking and on educating rather than training, using technical material only as illustration.
