Ever wondered why you always have to use 'precious' metals for things like electrolysis and car catalytic converters? Well, it's because Gaia can't afford to have these very basic processes of altering carbon dioxide, hydrogen, sunlight (and whatever, I don't know the chemistry) going on wholesale, but it does need them at the margins, so it makes sure that only relatively rare elements can do the job.

What is rare is not necessarily precious so all we have to do is to work out why certain rare(ish) elements are precious and we have the whole story. Kindly get to it.

Isn't it just the anthropic principle? If there were too many destabilising elements the world would be too random and intelligent life would not exist to see it.

To quote Wikipedia:

In astrophysics and cosmology, the anthropic principle is the philosophical argument that observations of the physical Universe must be compatible with the conscious life that observes it. Some proponents of the argument reason that it explains why the Universe has the age and the fundamental physical constants necessary to accommodate conscious life. As a result, they believe that the fact is unremarkable that the universe's fundamental constants happen to fall within the narrow range thought to allow life.


I really must send them some money next time they ask.

Rare things which taste good or are pretty become precious because only rich people can own them.. That's true even if the rare thing is no better than a cheap alternative.

Notice how a Rolex is worse at keeping time than the cheapest quartz watch, and fried sardines taste much better than caviar.

The evidence for SCUM keeps piling in

I have SCUM scheduled for Book Three.
  • Book 1: The Weather Underground
  • Book 2: Hydromorphography (Split Level Ocean Theory)
  • Book 3: Archimedes Lever (includes SCUM)
  • Book 4: Echoes of the Ice Age
Each book builds from the one before it. But all depends on me finishing Book 1. I'm happy with it. I will say that much. But it is slow going.
