Highlander 2

This must have been a very strange movie to make.

Edit 1: It continuously gets worse. Time travelling alien prison was a high-point.

That isn’t a statement often said.

Edit 2: I didn’t understand. I read the plot synopsis and thought it was terrible. I thought the plot was why it was terrible.

The plot is the best part.

Edit 3: In the future, OSHA doesn’t exist.

Edit 4: Okay seriously, that didn’t even register.

Logistics Map 2

Following this.

So the leading digit graph looks pretty much the same between 10 iterations and 10,000. The double leading digit graph doesn’t. Is that a resolution issue or indicative of some deeper, underlying property?

Let’s do a million iterations, for 1,000,001 values of x.

The double leading digit graph looks fairly similar to the n=10,001 graph.

But there’s a catch.

The 11423 (a) iteration yielded x = 0.5 due to truncation error.

The next time that happens is n=44063. (b)

It happens again at 79519. (c)

(c-a)/(b-a) =|= 2

Inception noises.

Logistics Map

Want to see something weird?

The Logistics Map is the iterative function: xn+1 = a*xn*(1-xn) where xn is some number between zero and 1, non-inclusive, alpha is a number between zero and 4, and xn+1 is the number you get when you do the math on xn.

So pick an x value arbitrarily: 0.6. x1 = 0.6

Pick alpha arbitrarily: 3.56995. alpha = 3.56995.

x2 = 3.56995 *0.6 * (1-0.6) =3.56995*0.6*0.4= 0.854388

That’s xn+1. xn in this case is x1. Think of xn+1 as being the next x. So you have a first x, 0.6, and the next x is 0.854388, and the next x is 0.438041158193768.

I picked the alpha because the numbers are highly chaotic and don’t go outside (0,1). The parenthesis means 0 and 1 are not included.

Then, for funsies, I bin the leading digits. So x1 is 6, x2 is 8, x3 is 4, etc. Zeros are never leading digits, so if a number was 0.0002, the leading digit would be 2. For extra funsies, I do the same for the first two digits below. (The images are named after the number of times I go through the function, so they’re 10s +1)

This is the plot of the first 11 values:

Okay, so what?

This is the first 101 values:

This is the first 10,001:

The shape doesn’t change. Oh, it squiggles a little. Here’s the first 4:

Other than resolution improvements, the shape remains basically the same for the leading digit graph. Does it do that for the double leading digit graph?
