acceleration

A minutephysics explainer on the twins paradox in special relativity. It shows why the traveling twin ends up younger and how acceleration resolves the paradox.

Carwow's review of the McMurtry Spéirling, a 1,000hp electric fan car that generates huge downforce at standstill and reaches 0-60mph in about 1.4 seconds.

A 33c3 talk by marcan on reverse engineering the PS4 hardware to run Linux with 3D acceleration. It covers how the console differs from a PC and includes a story about tunneling PCIe over RS-232.

David Sachs of InvenSense explains how gyroscopes, accelerometers and compasses work on their own and together, demonstrated on a modified Android handset. He covers sensor fusion algorithms and why rotation math such as Euler angles matters.

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.

Dragan Djuric presents Clojure libraries for GPU and numerical computing, including ClojureCL, ClojureCUDA and Neanderthal. He shows how a dynamic REPL workflow can be combined with low-level hardware acceleration for machine learning and data science.

Short footage of a Sprint missile from the 1970s Safeguard anti-ballistic missile system launching. The uploader notes the video is not sped up and that this is how fast it takes off.
