- 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.
- Boltzmann brain (Wikipedia)
The Boltzmann brain thought experiment suggests that it might be more likely for a single brain to spontaneously form in a void, complete with a memory of having existed in our universe, rather than for the entire universe to come about in the manner cosmologists think it actually did. Physicists use the Boltzmann brain thought experiment as a reductio ad absurdum argument for evaluating competing scientific theories.
