A short clip demonstrating a phone-based social engineering trick in which a crying baby in the background is used to pressure a customer service rep. It shows how attackers exploit human sympathy rather than technical flaws.

Practical Engineering explains pumped storage hydropower, which makes up most grid-scale electricity storage. It covers how it works and why it fits only certain geographies.

Practical Engineering compares modern concrete with that of the Roman Empire, covering modern techniques like roller compacted concrete and water-reducing admixtures. It explains the tradeoffs of Roman construction versus reinforced concrete.

Practical Engineering explains what a 100-year flood actually means, combining statistics, hydrology and how society treats risk. Grady walks through local drainage infrastructure and the caveats in estimating flood probability.

Real Engineering examines whether greening the Sahara could draw down carbon and slow climate change. It concludes that the effort would be enormously costly and that changes in albedo and other effects undercut the climate benefit.

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.

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.

Hamish Coleman describes reverse engineering the keyboard controller in a Thinkpad and reflashing it with custom firmware. He covers how Lenovo secures its firmware, and his ongoing work on the protocol between the BIOS and the vendor flash tool.

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.

Alex Ionescu's OffensiveCon 2019 keynote on how reverse engineering is done on Windows without conventional reversing. It covers legal ways to obtain names of variables, exported functions and structures.

A Kurzgesagt animation on using gene drives to modify mosquitoes against malaria, and whether we should. It explains the mechanism and the ethical trade-offs.

Tom Scott tells how John Reber's plan to dam San Francisco Bay was disproved by the Army Corps of Engineers' giant hydraulic Bay Model in Sausalito. The model showed the plan would have been dangerously wrong.

Matt Parker's Royal Institution talk based on his book Humble Pi, covering everyday mathematical mistakes and spurious patterns that went wrong in engineering and software. It mixes stand-up comedy with stories of coincidence and error.

A short unscientific fire test comparing a massive timber house with an ordinary house. It shows the wood chars and burns slowly while still holding together.

Short British Pathe newsreel footage of the 1940 collapse of the Tacoma Narrows Bridge as it twisted and swayed in the wind. The only casualty was a dog left in a stalled car.

Bryan Cantrill's Monktoberfest 2016 talk on how software engineers pass knowledge down through oral tradition, from folk rhymes to programmer lore and stories like why C lacks a logical XOR. He argues for writing software with future generations in mind.

NASA JPL engineers explain the final minutes of the Curiosity rover's entry, descent and landing on Mars, which combined aerobraking, a parachute and a skycrane. It lays out the tight sequence of events that all had to work automatically.

Christopher Domas's REcon 2013 talk on dynamic binary visualization for reverse engineering. He shows how rendering binary data as interactive visual maps and trigraphs reveals structure that hex dumps hide, leading to his Cantor.dust tool.

Jayson E. Street's DEF CON 19 talk shows photos from real security engagements where he was already inside client facilities, illustrating how social engineering and physical intrusion can cause huge losses. For each attack he also explains what defenses would have stopped him.

Veritasium rides a boat across the Los Angeles reservoir covered in 96 million black plastic balls. He explains why they were really introduced, which was not primarily to reduce evaporation.

A half-hour television special on the 2007 fiery collapse of a connector in the Bay Area's MacArthur Maze and its rebuilding in 26 days. It was produced for the Professional Engineers in California Government.

A one-minute clip from Insider showing an Airbus airliner's wings flexing far more than most people expect during a wing load test. It is meant to reassure nervous flyers about turbulence.

A one-minute National Geographic clip of researchers Terry Hunt and Carl Lipo testing a theory that Easter Islanders used ropes to rock the moai statues upright to walk them to their platforms.

Tom Scott visits ThyssenKrupp's test tower in Rottweil to see the Multi, a rope-free elevator that uses linear motors to move cabins sideways as well as vertically.
