- Time Person of the Year (Wikipedia)
Person of the Year (called Man of the Year or Woman of the Year until 1999) is an annual issue of the American news magazine and website Time featuring a person, a group, idea, or object that “for better or for worse… has done the most to influence the events of the year”. The editors select the featured subject, though the Time website or a partner organization also runs an annual reader’s poll that has no effect on the selection.
- Double-slit experiment (Wikipedia)
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.
