That was the first Class IV object to be discovered.Д¬lass V patterns behave seemingly erratically- chaotic, as we would say today-until they eventually collapse to one of the aforementioned classes.Д«ut some patterns are doomed to a different fate: remaining in a perpetual state of chaos-forever evolving, yet never stabilising onto something predictable. An oscillator that, every 30 generations, spawns a new glider. The American Mathematician and Programmer Bill Gosper responded with what is now known as the Gosper glider gun. And yet, they play a fundamental role for all Mathematicians and Computer Scientists interested in studying Life from a more вЂњacademicвЂќ point of view.ДЄ major breakthrough occurred in 1970, when Conway himself offered $50 to the first who could find a configuration which grew indefinitely. Gliders are the smallest spaceship known to exist. They effectively вЂ¦move! The most well known and loved is, without any doubt, the glider.Дiscovered in 1969 by the British Mathematician Richard Kenneth Guy, it was named by John Conway himself, due to a property it exhibits called glide symmetry. Those are oscillators that, at the end of their cycle, somehow find themselves in a different position. Oscillators of period 43 or greater can be constructed thanks to a pattern called the Snark.Д¬lass III groups some of the most studied patterns: spaceships. It was named David Hilbert (below), as a reference to HilbertвЂ™s list of 23 unsolved problems in Mathematics.

Last year, Luka Okanishi discovered the first oscillator of period 23. And indeed, finite oscillators are known to exist for all periods вЂ¦except 19, 38 and 41. Many believe that oscillators of any period can be constructed in Life. The blinker, for instance, repeats after two generations hence it has period two. They are classified based on their period. CharacteristicsД¬lass I are the so-called вЂњstill lifesвЂќ: patterns that do not change over time.Д¬lass II are called вЂњoscillatorsвЂќ, and they repeat over a certain number of generations. It is in there that its editor, Robert Wainwright, published a system to classify the many objects- patterns, as theyвЂ™re called-that he saw appearing in the game. ClassificationДЄfter its first publication in Scientific American, Life got so popular among Mathematicians that a quarterly newsletter called вЂњLIFELINEвЂќ started appearing. They called them cellular automata.ДЄ good read-although a bit dated-is von Neumann bookвЂ™s, The Theory of Self-Reproducing Automata, which was edited and completed by Arthur Burks. They modelled them using two-dimensional grids, updated in discrete steps following precise and deterministic rules. Some thirty years prior to ConwayвЂ™s Game of Life, in fact, StanisЕ‚aw Ulam and John von Neumann explored the theory behind self-replicating machines. The idea was to find a simple set of rules which allowed the merger of two seemingly disconnected fields: Engineering and Biology. The mind behind this bizarre game was John Horton Conway, a brilliant British Mathematician fascinated by the exploration of Mathematics in its purest form: the recreational one.Д¬onway had carefully designed the rules behind this вЂњgame of lifeвЂќ with the intent of making its evolution unpredictable. Each square adjacent to exactly three pieces gives birth to a new piece. Likewise, every piece next to one or no pieces at all dies from isolation. Each piece surrounded by four or more pieces dies from overpopulation. Every piece surrounded by two or three other pieces survives for the next turn. A вЂњzero-player gameвЂќ with no winners or losers, which result is fully determined by the initial configuration of the pieces on the board.ДЄ player is only needed to advance the state of the game to the next turn-a вЂњgenerationвЂќ-following three simple rules.

But unlike Chess and Go, it requires no players. Like Chess and Go, Life is played with pieces on a board. That was going to become one of his most successful columns. In the October 1970 issue of Scientific American (below), Gardner talked about the вЂњfantastic combinationsвЂќ of this new solitaire game called вЂњlifeвЂќ.

вЂњLifeвЂќ gained popularity after appearing in a column written by Martin Gardner called вЂњMathematical GamesвЂќ. IвЂ™m Alan Zucconi, and in this short documentary we will get lost in the endless complexity of a game so apparently simple that its creator called it вЂњLifeвЂќ. Like Chess and Go, sometimes complexity can hide in the most вЂ¦unexpected places. Emergent behaviours oftenвЃ -wellвЃ , emergeвЃ -from simple, discrete rules that have seemingly nothing to do with them. In reality, the more rules a system has, the more вЂњconstrainedвЂќ it is. One of the most common misconceptions is that complex phenomena arise from complex rules.
