It seems that entroy – according to [[Brian Greene]]'s explanation in video tktktk is thus: Low variability in relationships, ratios between variables (distance between atomic nuclei) equals low entroy. A 3D lattice of atoms where every atom is on a perfect grid, all have the same distance, that is ordered, that is low entropy.
You can describe their relationship with few informational bits.
I am yet to understand how entropy is decoupled from the human understanding of order and regularity. It seems very anthropocentric. But I know that this is at least in part due to my lack of understanding the maths behind it.
It has to do with the amount of information encoded in the situation – the amount of data required to describe the pattern. And therein lies the rub. The pattern we see and recognize might not – on a more fundamental level – be the simplest, most ordered.
You don't need a lot of information to describe a system with low entropy – Brian Greene, Darkness Visible: Shedding New Light on Black Holes
Describing each and every position of a particle as opposed to just describing a grid – a regular pattern – is… worlds apart in terms of information amount, but the pattern behind it… → I am jumping now, but this is where we look for a [[GUT]]. It seems that [[t.the search for a grand unified theory is the search for confirmation that our universe is ultimately of supremely low entropy]]
We only need a slight(ish) variation in our dopamine circuit to see paterns where there are none, re. [[schizophrenia]] at the extreme, and [[pareidolia]] which every. single. human. ever. is familiar with.
