- Saiph (Wikipedia)
Saiph /ˈseɪf/, designation Kappa Orionis (κ Orionis, abbreviated Kappa Ori, κ Ori) and 53 Orionis (53 Ori), is the sixth-brightest star in the constellation of Orion. Of the four bright stars that compose Orion’s main quadrangle, it is the star at the south-eastern corner. A northern-hemisphere observer facing south would see it at the lower left of Orion, and a southern-hemisphere observer facing north would see it at the upper right. Parallax measurements yield an estimated distance of 650 light-years (200 parsecs) from the Sun, which is about the same as Betelgeuse. It is smaller, less luminous but hotter at its surface than Rigel with an apparent visual magnitude of 2.1. The luminosity of this star changes slightly, varying by 0.04 magnitudes.
- 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.
