a whole made of parts, from the ground up
from the core definition we started with, we will now begin our journey into complexity. to avoid issues with things we don’t know much about (i.e., smaller than atoms), i will begin from the layer
onwards. why? considering the model is fractal itself, we can define
, where
is a sub element of an atom, thus avoiding many issues things of lower layers have. note that the properties of the things we will be dealing with may be broken down, as we noted above, into smaller parts, explained by the constituents for
.
so we can either say there are macroscopic properties of
such as mass, electronegativity and so on, or we can say the properties of
come from the properties of
. for example, we could say electronegativity has to do with the balance of positive and negative charges in an atom (a property of its constituents), or we can just say an atom has electronegativity as one of its properties. what we are doing is encapsulating questions into a bigger layer of abstraction, so we can work using only our small brains.
so it’s exactly what i’m doing, and why these terms i’ll be using can be broken down, but won’t. for the sake of validity, any thing has sub things, so if anyone wants to expand any definition to core terms they can do so.
so let’s see how simple laws can quickly show that the whole can be more than the sum of the parts.
let’s say we have water molecules. water molecules are a thing whose constituents are atoms (from layer
). so
where m means the “molecule” layer. to specify it completely, we would choose
. i will avoid breaking each one of these down but it could be easily done:
. this expansion, even though it’s for water alone, already would lead to a lot of unnecessary text. if we also add temperature constraints, isotopes, and so on, we would quickly run into in-computability again.
so one of the properties of the water molecule is that one of its constituents, hydrogen, tends to lose most of its electrons against the stronger oxygen. this leads to a water molecule that is charged in space (see picture). an atom alone is neutral, but when they band up together and create bonds, electrons flow and this leads to spatial charge. so even though the parts are “neutral” alone, the whole isn’t.
so consequence of the differences of its constituents, the whole (water) has a property that isn’t easily understood from the properties of its constituents, unless they are put together and interact.
so to formalize this, we would say we have both the properties of oxygen and hydrogen alone (their charge, their mass, etc), and the properties of oxygen and hydrogen together (how their different masses and charges lead to change in both of them).
this means that our formula for water would seem incomplete at the lever we’re working on.
. the fact that they are bounded has led to extra properties that were, even though explainable, not obvious.
this is where reductionists will say “yes, but the bonds are explainable by the laws that govern atoms themselves”, and it is correct. if i break down the higher level definitions, i will see that
isn’t really separate from the properties of
, rather it is just a property of when the two are together. on the contrary, emergents would claim that this property cannot be seen by the things alone, but only when the whole is created, which leads to emergence.
my answer is that these two claims are compatible. a thing alone is not a thing with another thing. like the two atoms, they bond naturally, therefore they are not entirely separate entities, with independent laws. their laws are generic enough to affect them and others irregardless of what type of atom it is.
a bond exists because the atoms allow for it, but is only possible when two or more are present. we will see this pattern in all layers of abstraction. some characteristics of laws (or properties of things) are only possible when their minimum quantity (as we defined it previously as the core mathematical concept) exists.
so the water molecule itself, as it turns out, also has charge itself (or a dipole), and its hydrogen atoms are somewhat naked versus the highly negative oxygen. what happens when we have a lot of water molecules together? is the law of charge attraction still valid as it was for atoms? as it turns out, yes. this law (the electric force between charges, part of the “physical laws” layer) requires the thing charge and the thing distance as its core properties. so atoms have charge, but apparently molecules have a kind of charge too, and the same with distance. so the law of electric force applies too. let’s formalize this.
, where
is, in this case, Coulomb’s law, and
becomes
and
becomes
. charge is there on both cases. but what is distance? distance is another law (this time from the realm of mathematics).
. this brings us a lot of interesting questions, but for now, let’s accept that distance is defined for two things with the single property position. note that it is arguable that position exists when there is no comparison to it, so it might be an illusionary property.
does hydrogen have position and charge? check
does oxygen have position and charge? check
do we have enough of them and are they close enough that they bond? check
the law can be applied. if it is, we have water now
does water have position? check
does water have some kind of charge? check
the law can be applied. we have water interacting with water now. a thing called hydrogen bonds appears for example, which is a property of water in groups, but not a property of water alone.
we slowly moved from the same law applying to atoms (and its constituents) to that law being applied to groups of atoms (molecules) and then the same law applying to molecules between themselves to form clusters of molecules. there are many examples of this in nature.
note that the only reason why this was possible was because:
- there are some invisible things in our universe (laws) that require very little properties to be applicable (like the electric force for anything with charge and distance), in essence, they are layer blind;
- there are things with the said properties so they are affected by these laws;
- there are things that when together with other things, have properties themselves also subject to the same laws, that were undefined for things alone (e.g., bonds).
this is only possible because some of the core things (laws) are layer blind. there is no semantics on charge. it behaves the same way for a molecule and an atom, or an electron and a proton, or the two terminals on a battery. this is what the standard model worries about, and what urges the physicists to claim everything can be explained by simple math. this is one of my favorite deepities, because even though it might be true, it is deeply false, since it explains the behavior of fragmented parts, oblivious of how hard it is to compute any interaction of two or more elements, no matter how simple (see the three body problem for example).
in this sense, we can see how nature itself speaks beyond abstraction, in a more essential manner. this follows the occam’s razor principle for the most part. why have two laws for layers, when the same can be used. occam’s razor is a natural consequence of a natural world with no semantics, no distinction of molecule or atom. in essence, a mindless world with random laws and consequences thereof.
the fact that we understand them, with our tiny brains, is a bit of a mystery. but we can easily see how we live in a world with simple laws but complex interactions. our complexity does not come from formal semantic differences. it comes from the simple excess quantity of things (in our planet at least).
the fractal nature of things exists solely because we have minds that require abstraction. as we saw from this example, abstraction is something we create in mind, because not even the basic laws of the universe seem any different between layers. pattern finding is something we do every day as humans, for survival. but it is also why we are so easily deceived by simple math versus the overwhelming torrent of random events that we swim in.
our journey will now continue on to bigger complexities. we started with the realm of the mathematician, then the physicist, now the chemist. we will visit many trades on our way. i’ll meet you there.
