- Space Invaders is a 1980 video game based on Taito’s arcade game Space Invaders (1978) for the Atari 2600. It was developed and released by Atari, Inc. and designed and developed by Rick Maurer. The game is based on the arcade game in which a player operates a laser cannon to shoot at incoming enemies from outer space. Maurer’s version has unique graphics and offers some gameplay variations. These include a two-player mode and variations that allow for invisible enemies and moving shields, and for enemies shots to zig zag and potentially hit players.
- Ernst Zermelo (Wikipedia)
Ernst Friedrich Ferdinand Zermelo (/zɜːrˈmɛloʊ/, German: [tsɛɐ̯ˈmeːlo]; 27 July 1871 – 21 May 1953) was a German logician and mathematician, whose work has major implications for the foundations of mathematics. He is known for his role in developing Zermelo–Fraenkel axiomatic set theory and his proof of the well-ordering theorem. Furthermore, his 1929 work on ranking chess players is the first description of a model for pairwise comparison that continues to have a profound impact on various applied fields utilizing this method.
