A game invented in October 2009 at First Flight High School where participants use the word appletart or some of its variants. Originally it was focused on who could say it the loudest but has evolved over time. The ways to play include: 1. Who can say appletart the loudest? 2. Who can say appletart the most in a game? 3. Who will say appletart last? 4. Who will day appletart in the funniest or most awkward situations? 5. What word will be matched when someone says appletart? Will it be appletart, applepie, poptart, or something else?1. kid 1: Appletart. kid 2: Appletart! kid 1: APPLETART!

A '''phase change''' is a perturbation of a periodic object which causes the object to skip ahead by one or more phases. If the perturbation is repeated indefinitely, this can effectively change the period of the object. An example of this phenomenon, found by [[:Category:Patterns found by Dean Hickerson|Dean Hickerson]] in November [[:Category:Patterns found in 1998|1998]], is given by [[28P7.1]]. In that example, the [[period]] of the oscillator is normally [[:Category:Oscillators with period 7|7]], but with the addition of a nearby [[mold]] its period is increased to [[:Category:Oscillators with period 8|8]] because of the repeated phase changes caused by the mold's [[spark]].

A phase is a representative generation of a periodic object such as an oscillator or spaceship. The number of phases is equal to the period of the object. The phases of an object usually repeat in the same cyclic sequence forever, although some perturbations can cause a phase change.

Phase change

A phase change is a perturbation of a periodic object which causes the object to skip ahead by one or more phases. If the perturbation is repeated indefinitely, this can effectively change the period of the object. An example of this phenomenon, found by Dean Hickerson in November 1998, is given by 28P7.1. In that example, the period of the oscillator is normally 7, but with the addition of a nearby mold its period is increased to 8 because of the repeated phase changes caused by the mold's spark.
