This week's featured article

Simkin glider gun is a glider gun, found by Michael Simkin on April 28, 2015. It consists of a Herschel running in two period-60 conduits, producing infinite copies of the first natural glider. In terms of its single-barreled form it is the smallest known gun, with 36 cells, sharing the record with the Gosper glider gun. In its pseudo-period, boat-bit form and its double-barrelled form it is the absolute record holder, with 35 and 29 cells respectively.

Did you know...

  • ... that as of 19 July 2020 there are 232 different still lifes known to be constructible by colliding four gliders, but it is likely that this list is not complete?
  • ... that in 2014 a new natural infinite growth pattern was discovered, starting from a symmetric random starting configuration?
  • ... that the first self-constructing Conway's Life pattern was built in 2010?
  • ... that the first glider synthesis for a c/3 spaceship was completed in 2014?
  • ... that the first "macro-spaceship" gun (a Gemini spaceship gun) was constructed in 2010, followed by the HBK gun in January 2015 and a Demonoid gun in December 2015?
  • ... that the waterbear was the first known high-speed oblique spaceship, many orders of magnitude faster than Gemini spaceships and half-baked knightships?
  • ... that there are no known direct reflectors for lightspeed wire signals, or for signals in 2c/3 wires, but that very large reflectors for these signals can be constructed using stable or periodic circuitry?
  • ... that 24 ten-cell patterns exhibit infinite growth, with 17 unique pattern types, but that it has been proven that no nine-cell pattern exhibits infinite growth?
  • ... that all still lifes up to 19 bits have a known glider synthesis, but it is still not known whether all still lifes are synthesizable?
  • ... that the French kiss remained without a glider synthesis until 2013?
