"Substances" are everything: neurons, brains, feelings, cells, living beings, elementary particles of the standard model of physics, electromagnetic radiation and other physical fields, atoms, molecules, neutrinos, crystals, liquids, gases, stars, star systems, galaxies, etc,
In addition, states of empty spaces (the vacuum in space) are also considered to be virtual substances.
Everything in the content of the universe is considered substance: in large ones like galaxies - which are less than tiny in relation to infinity - or in small ones like elementary particles. And of course everything in humans (like the brain).
"Law" means that identical parts - or waves - always result in identical structures under identical circumstances. Laws are inherent properties of substances that - viewed in isolation - are unchangeable (apart from the basic possibilities for modification contained therein) as long as nothing is added to or removed from the substances.
And that means that everything can only take place in a very specific legal form.
Substances and laws belong together directly and inseparably. There are no substances without laws.
The formula: substances = laws is universal.
