There are two concepts you might want to incorporate into your thinking on this topic. Neither one of them is the “answer” but they might take you off in a direction that leads to an unexpected connection. The first is emergence. Within the field of nanotechnology, emergence is a big deal. Size matters much more with nanotechnology than most other fields since many of the properties that apply at the macroscale do not apply at the nanoscale (under 100 nanometers or one ten-millionth of a meter). Consider cutting a cube of gold into smaller and smaller pieces. All the gold bricks’ physical and chemical properties will be unchanged. This much is obvious from our real-world experience – at the marcoscale chemical and physical properties of materials are not size dependent. It doesn’t matter whether the cubes are gold, iron, lead, plastic, ice, or brass. When we reach the nanoscale, though, everything will change, including the gold’s color, melting point, and chemical properties. The reason for this change has to do with the nature of the interactions among the atoms that make up the gold, interactions that are averaged out of existence in the bulk material. Nano gold doesn’t act like bulk gold. The coupling of size with the most fundamental chemical, electrical and physical properties of materials is key to all nanoscience. With the Big Bang, particles of energy and atoms were created with certain properties that govern all larger building blocks and processes of life on Earth. Atoms combine to form molecules, molecules combine to form molecular networks, and so on up to the planet’s ecosystem. With each new level of atomic construction, new properties and interactions emerge that did not exist at the previous level (but are governed by the properties of the preceding levels). One way to think about this is as a complex system – specifically a system whose properties are not fully explained by an understanding of its component parts. Complex systems consist of a large number of mutually interacting and interwoven parts, entities or agents.

In the context of taste and predilection, it’s an interesting question what tendencies or preferences emerge from our genetic makeup and physical condition. For example, pheromones play a huge role in the animal kingdom – and with humans. The series of reactions those chemicals trigger in our body depend on the chemistry of our body – and our overall body chemistry emerges from other individual chemical properties.

The second concept is chaos theory. In mathematics and physics, chaos theory describes the behavior of certain nonlinear dynamic systems that under certain conditions exhibit a phenomenon known as chaos. Among the characteristics of chaotic systems is a sensitivity to initial conditions (popularly referred to as the butterfly effect). As a result of this sensitivity, the behavior of systems that exhibit chaos appears to be random, even though the system is deterministic in the sense that it is well defined and contains no random parameters.

The thing in your post that triggered this thought is your comment that “we frequently see evidently happy couples and wonder what it is they could have in common or question how nature works in such strange ways.” I was talking to someone about this the other night and he told me that he thought it was almost random which couples stay together over the long term and which relationships fall apart. He’s seen situations where everyone thought a couple was rock-solid and then broke up and other situations where everyone predicted the couple would never make it and they did. That got me wondering whether there is a sensitivity to initial conditions at play with relationships. Just like a butterfly’s wings eventually causing a tornado, perhaps small changes in the initial conditions of a relationship cause a chain of events leading to large-scale phenomena (a break-up). This might even take many years to manifest itself – although the result was deterministic from the start.

Anyway, two random thoughts. Perhaps useless. Perhaps useful in making other connections.
