Mick West analyzes the Navy's Gimbal UFO video and gives four checkable observations suggesting it is an infrared glare that appears to rotate because the camera rotates while tracking. He argues the object is likely a hot craft hidden behind the glare.

The first lecture in an 18-part series on digital photography from Marc Levoy's Stanford CS 178 course, recorded at Google in 2016. The series covers how digital cameras work and computational photography, with slides and assignments available on the course site.

Benn Jordan explains how Flock Safety's license plate cameras log and share vehicle locations, and explores how adversarial AI can defeat them. It covers weak security and the surveillance risks of private police-camera networks.

Michael Oswald's documentary, based on Richard Werner's book, argues that Japan's 1990s crash was engineered by the central bank and powerful interests. It focuses on the Bank of Japan's hidden influence over the economy.

Sped-up onboard camera footage of the Falcon 9 first stage landing on a drone ship during the THAICOM 8 mission on May 27, 2016. It shows the descent from grid fin deployment to touchdown.

Raw 500 fps footage from Camera E-8 on the launch tower for the Apollo 11 Saturn V liftoff, transferred in HD from the 16mm original. More than eight minutes of film covers about 30 seconds of real time.

Mark Rober tests whether self-driving cars can be fooled, comparing a lidar-equipped car with a camera-only Tesla in scenarios including a painted Wile E. Coyote wall and smoke.

Robert Llewellyn of Fully Charged takes an early, 19-minute test drive of the Honda e electric car in Frankfurt. He looks at its acceleration, camera wing mirrors and tight turning circle.

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.
