Short Curious Droid video on why NASA could not simply rebuild the Saturn V's Rocketdyne F-1 engine for the SLS boosters. It explains that the engines were hand-tailored and that much of the know-how was never documented, so the blueprints were not enough.

Cockpit footage of a Swiss Airbus A340 crew dealing with rising oil temperature in one engine on a Zurich to Shanghai flight, ending with a safety landing. It shows the pilots' procedures through the emergency.

Engineer Stuff Made Here builds two new supposedly unpickable locks with different designs and sends them to the Lock Picking Lawyer to see whether they can be defeated. The video covers the novel anti-picking mechanisms.

A Disney Research SIGGRAPH 2013 demo of an interactive system that lets non-experts design animated mechanical characters. The user sketches motion curves and the system generates optimized mechanisms and gear trains for 3D printing.

Stuff Made Here designs and builds an "unpickable" lock, then calls in a locksmith to see if it can be defeated. It covers the mechanical design effort and the attempt to pick it.

Footage of an Airbus A380 engine blade-off test, in which a fan blade is deliberately released at full thrust to show the engine contains the failure.

A clip of Sandy Munro, a veteran automotive engineer, describing his visit to a SpaceX Starship design review and meeting Elon Musk. He says he was struck by how deeply Musk is involved in engineering.

Musician Thoj performs a live looping session on the Teenage Engineering OP-1 synthesizer, building a deep house track layer by layer.

John Lin reveals a rewritten voxel engine demonstrated in a Crystal Islands scene, with much finer voxel detail, fast collision, fracture and path-traced global illumination.

Roman Mars gives a funny TED talk on vexillology, laying out five basic principles of good flag design and why many city flags fail them.

Kurzgesagt's animated explainer on CRISPR gene editing, covering how the technology works and what it could mean for curing disease, designer babies and aging. It frames genetic engineering as an irreversible change coming to humanity.

Tim Dodd of Everyday Astronaut talks with Elon Musk right after Musk's 2019 Starship presentation. Musk discusses Starship's design, why SpaceX favors conventional engines over aerospikes, and how deleting parts and processes speeds up development.

A GameTrailers walkthrough from E3 2012 of an Unreal Engine 4 real-time tech demo with Epic's Alan Willard. It shows live code changes and hot reloading while the game runs.

CGP Grey discusses flag design principles and grades flags, following the Minnesota state flag redesign. It argues for simple, distinctive flags.

Wildlife videographer Dani Connor Wild talks with Oscar-winning sound designer Mark Mangini about how her red squirrel recording became the desert mouse sound in Dune.

Neil Cicierega's parody song 'Redesign Your Logo', played over a live backing video with corporate PowerPoint visuals. It mocks the infamous Pepsi design strategy presentation.

First of an 18-part lecture series by engineer Dan Gelbart on building prototypes. The series covers practical mechanical design and fabrication of precision machines.

Not Just Bikes explains why cars rarely crash into buildings in the Netherlands, attributing it to street design that forgives mistakes and to systematic crash investigation. It contrasts this with North American acceptance of such crashes.

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.

A 10-minute clip from a Jonathan Blow Twitch stream in which he argues that game engines do not really need separate scripting languages. He questions the value of embedded interpreters when the main language can do the job.
