- In modern physics, the double-slit experiment demonstrates that light and matter can satisfy the seemingly incongruous classical definitions for both waves and particles. This ambiguity is considered evidence for the fundamentally probabilistic nature of quantum mechanics. This type of experiment was first performed by Thomas Young in 1801, as a demonstration of the wave behavior of visible light. In 1927, Davisson and Germer and, independently George Paget Thomson and his research student Alexander Reid demonstrated that electrons show the same behavior, which was later extended to atoms and molecules. Thomas Young’s experiment with light was part of classical physics long before the development of quantum mechanics and the concept of wave–particle duality. He believed it demonstrated that Christiaan Huygens’ wave theory of light was correct, and his experiment is sometimes referred to as Young’s experiment or Young’s slits.
- 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.
