Tonight, I have only a small observation to offer about the real world. And that regards apples. It’s not about how apples fall from trees towards the earth’s center. Isaac Newton already covered that. What I’ve noticed is that when you bite into a moldy spot on an apple, it tastes like dirt.

But OK, then – that makes rough sense, given that soil has a lot of rotting leaves and grass and tree branches in it. Dirt is a mix of sand (little particles of rock) and organic stuff, and the organic stuff is a breeding ground for bacteria and other microbes. And all those little microbes probably produce the same chemicals in dirt that they produce in apples, which are organic things. Not that you want to eat those rotting brown spots, or that rotting brown earth; but all this rot obviously has a role in how and why things grow, in the cycle of ecology.

I’ve also been dabbling a little in Julian Barbour’s “Platonia”, a timeless, probabilistic state-space that (in theory) pre-figures both classical reality and quantum reality as we know them; and with the grounds for number theory (courtesy of Douglas Hofstadter in “Godel, Escher, Bach”). But right now, dirty apples are about the best I can do in terms of explaining just why this world is the way it is.
