- Reverse-engineering a three-axis attitude indicator from the F-4 fighter plane (righto.com)
We recently received an attitude indicator for the F-4 fighter plane, an instrument that uses a rotating ball to show the aircraft’s orientation and direction. In a normal aircraft, the artificial horizon shows the orientation in two axes (pitch and roll), but the F-4 indicator uses a rotating ball to show the orientation in three axes, adding azimuth (yaw).1 It wasn’t obvious to me how the ball could rotate in three axes: how could it turn in every direction and still remain attached to the instrument?
- The Education of a Libertarian (cato-unbound.org)
Peter Thiel shares the belief that politics is mostly futile, a conclusion he reached after years of activism. In particular, he believes that democratic politics is unlikely to bring about libertarian outcomes. Fortunately, politics is just one sphere of human life, and it’s possible, he argues, to create technologies that minimize its reach. Thiel describes a “deadly race” between politics and technology, in which human freedom is the prize. The goal of libertarian activism should not be to win in politics, he argues, but to escape it.
