As we continue our close look at the human brain, we take some time to look at how it grows and develops. The story starts before you are born, when a man and woman love each other very much, and…

Finally done with natural history, today we start talking about the brain. It is extremely complicated. Even a single brain cell, one neuron, is an intricate little machine. Today we take a look at the neuron, and how it sends signals.
I’m sitting on the edge of a binary ocean, casting hyperdimensional nets into the infinite waters of possible programs. My digital creatures, which I call “figures,” will run on my computer for hours, until I finally catch something.

Small sample sizes and all those caveats.
I’m tossing out the number of figures being born as a threshold. That will pop out of any of them at any time, and it’s just luck. One of them starts reproducing very quickly, and happens to find a window of relatively few mutation’s, and then skate on through to the finish line.
I retested the first five populations, snagged with a threshold of 100 and 100,000, if memory servs me. Looking at the most mutations given to a population, side by side results, first five and latest five.

It seemed like a good idea. Let evolution solve the mutation problem for me. This is procrastination, as what I really need to do next is update the documentation and archive this version. It’s time to clean up the code and concentrate on making the system run faster. Still, I had a few days, and I’d notice that some populations were much more resistant to mutation than others.

figures just fat

61.pop keeps doing too well to tell
I was trying to make s.pop into a six figures steady pop size stable population. I wanted to recreate 6.pop whose magic children have done so well that they climb off the measurement scale. I set things up so that s.pop was read from disc and stored in memory. Then, when s.pop died out, she’d be restored from memory rather than from disc. Mutations would happen unless the population was within a certain size range. Once it was all ready and as tested as I was willing to bother with, I let er rip.

For our final episode on the topic of natural history, we take a look at the Pleistocene. This epoch was the most recent ice age, and toward the end of this time, lots of the largest land mammals went extinct, while in the middle of the epoch, humans finally arrived on the scene.

I managed to talk Phil into co-hosting again, even though he’s far away. Thanks to the internet, we talked about the Pliocene. At the beginning of this time, a nearly dry Mediterranean basin was flooded by the sea, causing a global drop in sea levels. Later, north and south America were connected, allowing plants and animals to travel to new places. This included the largest cat and largest bear ever to roam the Earth.

It was raining. Safe from the downpour, I stood on the porch and enjoyed the weather. Fall is one of my top five favorite seasons, especially if I don’t have to be out in the rain. It was really coming down too, the air filled with the hissing roar of all that water smashing against all that ground. Against the roof, a more percussive pounding, while the bushes and trees in my yard played host to myriad tiny streams and rivulets cascading down their leaves and branches.

Picking it up from yesterday’s entry, I needed to confirm that the quick populations, those that produce new figures quickly, were as fragile as I thought, and for the reasons I thought. I started with m1.
