A cell has machinery within it that can build proteins to reinforce the cell wall strength. A cell can even replicate itself before its parts wear out. It is not a huge stretch to see how a cell uses agency and intentionality to extend its life span and pass on its genes to future generations.
Bubbles, on the other hand, have no pumps or flagella with which to manage environmental variability. Bubbles are a simple example of a closed system, meaning they are bounded without access to additional resources. Whatever measure of internal resources the bubble has initially will be used up rather quickly.
It would appear that bubbles are nothing but boundary! The bubble’s boundary separates the volume of air within it from the volume of air beyond it. These volumes of air determine, to some degree, the amount of pressure exerted on the boundary from either side. The larger the volume inside a bubble, the more the internal pressure and the less differential there would be between the internal and external pressures.
While inorganic entities are not thought to have conscious agency, they do endure a range of environmental variables, at least for a short while. A bubble is an elegant example of an intensional (rather than intentional) pattern, holding together some extensional matter.
All of a bubble’s organization is in its surface, or ‘skin’. A sphere, the shape of many bubbles, has a lower Surface Area to Volume ratio than any other shape. Compared here are the three forms with the lowest SA:V ratios:
This means a sphere can grow its volume (and internal air pressure) at a rate 4.836 times that of surface expansion. This ratio is helpful for bubbles, in that its volume creates the least stretching-out of it surface. The bubble, thought to be an inorganic closed system, intensionally incorporates beneficial features of geometry to extend its stint as an entity.
At some point, elasticity comes into play, and if the surface becomes too thin, the bubble will not be able to effectively mediate between the inner and outer spaces.
- by increasing the quantity of substance used in the bubble wall;
- by increasing the viscosity of that substance
- or by equalizing pressure differentials at the bubble wall.
Because we assume the bubble has no agency over its pressure differentials, or over the quantity or quality of its substance, we expect its durability to be fleeting and random — and so it seems.
But wait! Have you ever watched what happens to soap suds in your bathtub?
The combined volume of the two bubbles increases the internal pressure, while the layer of film that separated the two bubbles gets moved to the outside, thickening the exterior boundary.
Somehow bubbles have an innate tendency to survive in their environment by maximizing their volume within a range that can be accommodated by the tensile strength of the boundary material.
Wow! Bubbles are way smarter than we thought!
What does influencing a ferro-fluid (fluid containing iron particles) with a magnetic field have in common with blowing bubbles? Watch the short video and see if you can tell.
Ferro-fluid is similar to the soapy fluid in bubbles, in that the iron particles align with each other just as the soap molecules adhere to each other. The property of cohesiveness enables both of these fluids to form thin pliable sheets. The magnetic flux structures the ferro-fluid into shapes, just as air pressure differences structure soap films into bubbles.
With sufficient elasticity, the soapy water stretches around the air blown into it and the viscous ferrous fluid stretches over the wave crests, which spike upward from a magnetically disturbed surface.
Watch this video about Cymatics, the ability to make sound visible:
Granules were sprinkled on a metal plate and then sound caused the particles to be arranged into intriguing patterns.
A common dynamic links how granules distribute in different places on a vibrated metal plate and how a pool of ferrous fluid, under the influence of magnetism, climbs from an otherwise smooth surface.
The evacuation of particles from certain areas gives away the secret of unseen wave crests.
In contrast to the viscous fluids that stretch around the wave peaks, the granular particles on the two plates (shown above) lack cohesiveness, so the particles fall from invisible mountains to accumulate in surrounding valleys.
Frequency, Amplitude and Pitch
More intricate patterns emerge as the pitch of sound grows higher. For example, the photo on the right above represents a higher pitched sound than does the one on the left. A higher pitched sound makes a higher frequency wave (more cycles in the same time). Higher frequency waves have steeper slopes and shorter wavelengths, a wavelength being the distance from peak to peak, or from trough to trough, of adjacent waves.
So, the higher pitched sounds make steeper ‘mountains’ (referring once more to the ferrous conical mountains shown above). Steeper mountains have bases with smaller circumferences because more have to fit on the same surface area. This accounts for why the higher pitched sounds make lacier and more elaborate looking patterns.
From Probability to Persistence
The ferro-fluid did not form a sculpture until the magnetic field was applied to it. Soap film does not produce bubbles without being influenced to do so.
Given some soapy liquid in which to dip a bubble hoop, a child will experiment with waving the bubble wand faster or slower, or blowing through the hoop with more or less gusto, until just the right balance is achieved. Children want to make big bubbles, but not so large that they immediately pop. Once the youngsters have the knack striking the necessary balance between viscosity and air pressure — it is inevitable that some durable bubbles will be made.
The implication here is subtle. In that specific range of conditions (a sufficient amount of substance with good viscosity, coupled with appropriate air pressurization) in which bubbles may form and persist, is surely where bubbles will be found, whether scrutinized by a specialized scientist or marveled at by an excited child.
Between opposing forces there may be found a point, a line, a surface, or a volume of neutrality and balance. These oases, whether ‘valleys’, ground-states, or boundaries, are zones of minimized pressure. Low pressure zones are attractors. Everything falls toward an attractor. We fall in love with one who strongly attracts us. And, in Genesis, the spirit of God was attracted to the Female’s low-lying waters.
Whatever aggregates in these pockets of hospitality tends to remain there longer than they would elsewhere. The sand that settles in one place on the metal plates will not leave unless forced to do so by a change in the vibrational pitch. The particles resting on the still plate represent potential matter in a quiescent field.
The video below will show how standing waves provide attractors to light-weight objects, allowing them to be suspended in midair.
Particles OUTform into an attractive environment (where the vibration directs it to be).
We wrap up with a link to an interesting article about droplet physics.
