- Millipede (video game) (Wikipedia)
Millipede (stylized millipede in western releases and Milli-Pede in Japan) is a fixed shooter video game released in arcades by Atari, Inc. in 1982. The sequel to 1981’s Centipede, it has more gameplay variety and a wider array of insects than the original. The objective is to score as many points as possible by destroying all segments of the millipede as it moves toward the bottom of the screen, as well as eliminating or avoiding other enemies. The game is played with a trackball and a single fire button which can be held down for rapid-fire.
- 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.
