There's almost a pattern â€" and there's certainly some structure â€" in the primes when laid out in hexagonal and square spirals:

The square is known as an Ulam spiral; patterns show up in number spirals in most regular tilings.  They remain unexplained but (IMO) interesting.

Compare in article, the Ulam spiral vs a more random dot distribution ...

You can spot the more pseudo-random pattern at once.

Even the set of prime numbers isn't truly random:

I sure hope that is just some coincidence.  Because I thought prime numbers got unpredictable at some point.  Not that many aren't found but there isn't (supposedly) a way to calculate them.

Randomness can be measured, so it isn't just in the eye of the beholder.  This Ulam spiral is a clever way to bring out the non-randomness in a particular number series.

I think that Cavebear is thinking ... as we get to larger numbers, the average space between primes gets bigger.  As it must be.

So easy, even a Cave Bear can do it (see commercial).

We of the "Dreaded Cave" are sometimes embarrassed that the ways of the digital ancestors embarrass us in the ways of the digital descendants.  "Betwixt and Between" are not just the names of candy bars, you know...

You know, the standout statistic here is that all other questions show a significant decline from the oldest generation to the newest, except belief in Hell.  That's essentially linear.  Weird.

Guess that shows the power of playing on fears rather than hopes, that's my tentative explanation.

I noticed that.  How "the hell" can people believe in a deity less but "a hell" as much.  Illogical as it seems, I suspect most people are dumber than average.
