honeycomb decay

Mathematica can save time delays between frames together with animated GIF (look for "DisplayDurations" under options of GIF format). This in turn allowed me to produce exactly 28 frames for the decay of this honeycomb with 28 cells. Modelling radioactive decay, where for example time intervals between clicks on a Geiger counter are approximately exponentially distributed, I can simulate the delays (rounded and shifted to run from t1/100-th seconds with average value (t1+t0)/100-th seconds) as:

delays[{t1_, t0_}, n_] :=
 t1 + Round[
   RandomVariate[ExponentialDistribution[1/t0], n]]

I set t1=2 here. Most browser can't present a delay of 2/100-th seconds properly. Chrome can.

@nielsen Hey, no problem, and sure, feel free to pose questions. You might want to join chat though (top menu), there is a chat room "Discussion between BoLe and Aky", shall we converse there? Messages are stored and notifications done.

comment How to calculate the area of a listplot
Can you show the list resoluted-down perhaps? And could you close it to form a polygon for any practical purpose? For we know how to compute the polygon area...

@nielsen I think you should think it over again...I added few results ("chapter 3").

@Aky Sure, I can share my secrets. :) Can you make a room or where do you want to chat?

@Silvia True. I much prefer MapIndexed but it's kind of curiosity like you said, MapAll useful for once.

You can MapAll or //@ but then set first rule to {0, x}.

@nielsen Sort of noise, I see. I think those are solutions of FindRoot converging uncontrollably and to undesired roots. I added some code. Have you already moved on from this problem?

@nielsen Which y will you use with z, min or max? Both perhaps and calculating zmin and zmax, yes?

@nielsen Sort of forking occurs. Suddenly more solutions for y are possible depending on x.

@nielsen Right, something happens as denominator drops below 2. You can start analyzing that with Manipulate example above.

Right, Tanh[x], or just x, is a better seed.
