Destin Sandlin of Smarter Every Day gives a talk to an aerospace audience, comparing how Apollo was engineered and managed with NASA's Artemis program. He raises concerns about unresolved details, the number of launches and in-orbit fuel transfer needed to reach the Moon, and the loss of institutional knowledge.

Robert Moss's JuliaCon 2015 talk describes using Julia as a specification language for ACAS X, the next-generation airborne collision avoidance system that succeeds TCAS.

A short clip of Dr. Robert Zubrin, author of The Case for Mars, answering why humanity should go to Mars. He argues that societies grow by challenging themselves and that exploration inspires young people.

Bruce Waggoner of the Voyager team describes how engineers diagnosed Voyager 1's 2023 loss of telemetry and patched its flight software from 15 billion miles away. The talk covers the spacecraft's architecture and the scarcity of old documentation.

Nickolas Means tells the story of Lockheed's Skunk Works and how its engineers built the U-2, SR-71 and F-117 under tight deadlines and budgets. He draws lessons for modern software teams.

Stuart Armstrong of the Future of Humanity Institute gives an Oxford physics talk on what exploratory engineering suggests about the Fermi paradox. He argues that von Neumann probes and Dyson spheres are plausibly buildable and asks what traces advanced civilizations would leave.

An AdaCore webinar in which NVIDIA engineers explain why and how they adopted Ada and SPARK for security-critical firmware. It covers the business case and the engineering experience of the transition.

Sean Carroll's Talks at Google presentation of his book Something Deeply Hidden. He gives an accessible introduction to quantum mechanics and argues for the many-worlds interpretation and the emergence of spacetime.

Uber Engineering's Joseph Gilley explains why Uber uses hexagons for geospatial indexing and introduces H3, its open source hierarchical grid system. He covers use cases and how distortion is handled.

Michael Steil and Christian Hessmann's 34C3 talk explaining the Apollo Guidance Computer end to end: hardware design, operating system, and mission software.

Nickolas Means tells the story of United Airlines Flight 232, which lost all flight control yet saved more than half its passengers. He draws lessons on teamwork, crew resource management and leadership for software teams.

Astronaut Mike Mullane explains normalisation of deviance, where teams gradually come to accept violations of their own safety standards. He uses the Challenger shuttle disaster as the main case, drawing on NASA's ignored warnings before the launch. It is the first part of a talk given to a fire-fighters' association.

Retired Boeing Technical Fellow Doug McLean walks through common misconceptions in aerodynamics, drawing on his book Understanding Aerodynamics. He critiques popular explanations of wing lift and rocket thrust and argues for arguing from the real physics.
