### Re: Thread for basic questions

Q1: Do all oscillators whose rotors are 1 cell thick (i.e. the rotor fits in a 1xn bounding box for some n) have period 2 or 4? m=1, isn't it? The design of the unidimensional spaceship should allow for a variant that rebuilds itself in the same location. Every cell outside the 1xn region should be...

### Re: Unproven conjectures

Conjecture: The growth rate of the function f(n) is exponential or even faster. f(n) return the biggest non-infinite final population obtainable from a starting pattern that fit in a nxn bounding box. The function f(n) grows no slower than a busy beaver function, as we can simulate a Turing machine...

### Re: Thread for basic questions

Q1: Do all oscillators whose rotors are 1 cell thick (i.e. the rotor fits in a 1xn bounding box for some n) have period 2 or 4? Q2: What is the smallest number m such that the oscillators whose rotors are ≤m cell thick have unbounded period? The second question may be simplified by allowing infinite...

### Re: Thread for basic questions

Have any patterns been constructed such that no cell in the plane remains on permanently, yet the overall growth rate is clearly quadratic? e.g. a nonfiller whose "eating" reaction is slower than its "filling" reaction in much the same way as a growing spaceship would be? Make a puffer whose produc...

### Re: What is Doppler effect?

There is a use of the term "Doppler effect" on collidoscope.com . It refers to a "Diagonal Pattern Broadcast Bomber", i.e. a diagonal-moving pattern giving out diagonal waves in the four directions. The pattern is x = 12, y = 12, rule = 1c3e/23-ce/4 6.2A$5.ABCA$4.AB2C2A$3.ABC2.CBA$2.ABC4.CBA$.ABC3.C...

Maybe we should ask GUYTU6J because the only mention of the Doppler effect on LifeWiki is a GUYTU6J edit.
