- Bohr model (Wikipedia)
In atomic physics, the Bohr model or Rutherford–Bohr model is an obsolete model of the atom, presented by Niels Bohr and Ernest Rutherford in 1913. It consists of a small, dense nucleus surrounded by orbiting electrons. It is analogous to the structure of the Solar System, but with attraction provided by electrostatic force rather than gravity, and with the electron energies quantized (assuming only discrete values).
- Samurai cinema (Wikipedia)
Chanbara (チャンバラ), also commonly spelled “chambara”, meaning “sword fighting” films, denotes the Japanese film genre called samurai cinema in English and is roughly equivalent to Western and swashbuckler films. Chanbara is a sub-category of jidaigeki, which equates to period drama. Jidaigeki may refer to a story set in a historical period, though not necessarily dealing with a samurai character or depicting swordplay.
