This week's featured article


1×N quadratic growth is a pattern found by Stephen Silver on April 20 2011; it is the first pattern discovered that starts out with the thickness of a single cell and has quadratic growth. It uses the breeder from Nick Gotts' 26-cell quadratic growth.

On November 6, 2014, Chris Cain completed a 14812×1 pattern that exhibits quadratic growth — and on November 10th he reduced this to 7242×1.

Did you know...

  • ... that the smallest 31c/240 spaceship does not make use of the 31c/240 reaction?
  • ... that there is roughly one chance in 10^(N/3) that a still life appearing out of random soup will have a population of exactly N cells?
  • ... that the number of still lifes with N+1 bits is roughly 2.48 times larger than the number of N-bit still lifes?
  • ... that the odds of a randomly-chosen 20x20 soup pattern being a methuselah that lasts between 1000N and 1000(N+1) ticks, is roughly the same as the odds that it will last any amount of time longer than 1000x(N+1) ticks?
  • ... that all still lifes up to 16 cells can be synthesized at a cost of less than one glider per cell?
  • ... that the first elementary knightship, Sir Robin, was discovered only in 2018, with there having been a very close call in 2004?
  • ... that there is a 6x2 counterexample to the Coolout Conjecture, proving that patterns that are internally compatible with stability can not always be made part of a larger still life, no matter what cells are added around the edges?
  • ... that a Conway's Life pattern representing a complete programmable 8-bit computer, consisting only of buckaroos, p60 glider guns, and glider duplicators, was completed in November 2016?
  • ... that whilst no elementary oblique spaceships were found in B3/S23 until 2018, and none have occurred naturally, at least two naturally occurring reactions have been discovered in B38/S23 that travel in an oblique direction?
  • ... that not all 1.00 volatility oscillators are phoenixes, but volatility 1.00 period 2 oscillators must be phoenixes?
