Seeing Sound

In this TEDx talk, Michael Rubenstein, a research scientist, introduces the “motion microscope,” a video-processing tool that amplifies changes in motion and colour. This technique makes subtle motions visible such as the change of colour of a person’s skin as blood is pumped by the heart. Using a high speed camera, the technique can even…

Thrust Vector Control – SpaceX and Universality

“Engine failure modes are minimized by eliminating separate subsystems where appropriate. For example, the first-stage thrust vector control system pulls from the high-pressure rocket-grade kerosene system, rather than using a separate hydraulic fluid and pressurization system. Using fuel as the hydraulic fluid eliminates potential failures associated with a separate hydraulic system and with the depletion…
