This week's featured article

Recursive filter is a toolkit developed by Alexey Nigin in July 2015, which enables the construction of patterns with population growth that asymptotically matches an infinite number of different superlinear and sublinear functions. Toolkits enabling other sublinear infinite series had been completed by Dean Hickerson and Gabriel Nivasch in 2006 - see quadratic filter and exponential filter.

Did you know...

  • ... that the first spiral-growth pattern in Conway's Life was constructed in 2014?
  • ... that among known glider recipes for irreducible objects, the Gemini spaceship has the largest known minimal recipe, currently 173,449 gliders — the runner-up being the Parallel HBK with a 38,380-glider synthesis?
  • ... that it was shown in 2014 that any salvo of gliders, no matter how tightly packed, can be constructed by crashing together gliders whose initial positions are farther apart than any chosen finite distance?
  • ... that no spaceships with velocities other than c/4 diagonal (glider), c/2 orthogonal (*WSS variants), and c/12 diagonal (Corderships) had known glider syntheses until 2003, when a 2c/5 spaceship gun was constructed?
  • ... that after ten years with no new small spaceship syntheses, a glider construction was found for the c/7 loafer in 2013 less than three hours after its discovery?
  • ... that glider constructions for three previously inconstructible spaceships (the dart, the crab, and the Parallel HBK) were discovered in 2014?
  • ... that glider constructions for the B29, X66, half-X66 with HWSS, Pushalong 1, 25P3H1V0.1, 30P5H2V0, 30P4H2V0.4, a pufferfish spaceship, and the weekender were discovered in 2015 — after fifteen years of intermittent efforts in the case of the weekender?
  • ... that since 2014, more new spaceship syntheses have been completed than were found in all the years between 1970 and 2013?
  • ... 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?
