Kickbackreaction.png

The kickback reaction is a collision of two gliders resulting in a single glider travelling in the opposite direction to one of the original gliders. This is important in the proof of the existence of a universal constructor, Bill Gosper's total aperiodic, and many other constructions.

Besides the 90-degree collision shown here, one other two-glider collision with gliders meeting at 180 degrees also produces a clean output glider, and may also be called a "kickback reaction".

Pattern collection

The LifeWiki contains one of the most comprehensive catalogues of patterns available on the internet. Within it you will find:

Did you know...

  • ... that there are now over a hundred and twenty known Herschel conduits, counting stable conduits only, and a much larger number if oscillator-supported conduits are included?
  • ... that Demonoids, caterloopillars, orthogonoids and half-bakery knightships are the only known types of spaceships with fixed slope but adjustable speed?
  • ... that a pattern exists in which no cell in the unbounded Life plane ever becomes periodic?
  • ... that several candidate universal constructors have been demonstrated in Conway’s Life, but as of June 2015 none have been formally proven to be universal?
  • ... that there are dozens of known Cordership variants, including puffers, rakes and wickstretchers, with periods of any multiple of 96?
  • ... that greyships have been constructed with speeds of c/2, c/3, c/4, c/5 and 2c/5?
  • ... that most greyships travel parallel to the stripes in their included agars, but a few travel perpendicular to the stripes, or "against the grain"?
  • ... that a pattern has been constructed that calculates and prints out the digits of pi in decimal, and a similar one prints out the decimal digits of the Golden Ratio?
  • ... that several different patterns have been constructed to calculate and display the sequence of prime numbers, and some have been adapted to display only prime pairs or Fermat primes?
  • ... that two completely different types of oblique spaceships, the waterbear and the half-baked knightship, were constructed in 2014?
