Atomic Humans

Some themes appear to exert a magnetic pull on my attention: I keep coming back to them and often feel like I’m on a treadmill. It’s hard to figure out why: why am I compelled to keep these topics alive? A recent insight ties some of it together.

Years ago, I wrote a post called A Physics-based Diet Plan. The premise is that humans do not create or destroy atoms within their bodies, and that the energetics are too minuscule to register measurable mass–energy conversion. As such, a person’s mass change—as measured on a bathroom scale, for instance—from one day to the next is completely captured by the difference of mass inputs and mass outputs. It’s just atoms in and out.

Now, the human body has many channels for mass loss. Bathroom functions, breathing (net carbon/water loss really adds up!), and perspiration being the main mechanisms. Mass gain is almost entirely through our pie-holes. And entry via that channel is almost always facilitated by a hand delivering food to the mouth under the control of a brain. If you want to lose weight, the directive is simple: eat less and breathe more. In other words: diet and exercise. I know: radical, right? Every successful program for weight loss involves essentially this same advice, in various guises. That’s because it’s just atoms in every single case, at the foundational level. But oh boy, you wouldn’t believe the resistance I get to this framing. Let’s talk about that…

How Much for One Protein?

Showing my age a bit, a young Chris Rock in a 1988 movie amusingly asks: “How much for one rib?” Given that the crafting of a single protein plays a central role in this post, and ribs are a source of protein, the association was too much for me to pass up in the title.

I’ve pointed out before that our most elaborate inventions absolutely pale in comparison to even the simplest form of Life. Our gizmos can’t self-replicate, heal wounds, feed themselves, stave off pathogens, or self-evolve. Even though both gadgets and Life appear to be based on atoms and the same fundamental interactions, the level of complexity in Life is far beyond our means to create. At best, we bootstrap and copy.

To make the point, we’ll embark on a well-funded thought experiment that is able to assemble the top talent from around the world in a team given one mission: generate the genetic coding that would carry out a specific novel function by way of synthesizing a novel protein specific to that task. We stipulate a novel function that hasn’t arisen in any lifeform, otherwise the open-book (Google-connected) nature of this test would instantly result in “cheating” off a billion-year heritage.

Let’s see how they do.

Decisions, Decisions

Which way will the coin decide to land? Image by ICMA Photos.

In my continuing pursuit of humility as an antidote to modernity’s human supremacy illness, the atoms that constitute who I am take issue with lofty and self-aggrandizing concepts of idealism, dualism, and free will—replaced by the unflattering material world and its staggering wealth of emergent complexity. I have argued that opposite of lacking imagination and being reductionist, such a view far exceeds our imaginative capacity and is in fact rather expansive and open-ended next to facile short-cut cop-outs that sweep mind-boggling complexity under the rug by pretending that constructs like mind, consciousness, soul, God, or Santa Claus are real.

One stubborn sticking point is the beguiling illusion that “we” are separate from “our” corporeal bodies, owning and controlling them, somehow. This notion is prevalent, despite zero evidence that we are anything but corporeal, and heaps of evidence to the contrary. A less supremacist variant allows that all life, down to microbes, are endowed with this material override to exert control and autonomy over their environments, but still demand a line of separation between life and inanimate collections of matter. An amoeba suddenly changing course in reaction to its environment is, in this view, ontologically different than a hurricane changing course in reaction to its environment.

Granted, life is amazing and exhibits unambiguous behavioral differences compared to, say, rocks (hint: check the complexity of internal structure). A materialist, mechanistic basis does not in any way diminish life, although that’s often the regrettable reaction from someone who takes it on faith that transcendent mystery accounts for life’s splendor—rather than intuition-busting eons of emergent material fabulousness. Well, it turns out that life is incredible no matter what inconsequential thoughts we form about it. In any case, the point that I will develop in this post is that “decisions” are carried out at every level from electrons to ants, but are at no point fundamentally operating on a different basis.

Depending on how one defines “decisions,” either electrons and bats carry them out by the same rules, or neither can be said to be making “free” decisions. Whatever the case, electrons and bats are on similar footing when it comes to “decisions,” albeit at vastly different scales of complexity. Given enough information and background, the decisions by either are not surprising, even if not precisely predictable. Now, I do identify a difference between living decisions and inanimate decisions, importantly, but it’s a subtle one that I’ll wind my way toward.

For the Love of Newts

Photo by author

Happy Newt Year! Those who have followed me for a long time have probably noticed a marked uptick in the frequency of newt mentions in the last few years. What’s the deal with that? It seems so random. Am I engaging in occult practices that require eye of newt?

The simplest version is that when I moved from San Diego back to the Pacific Northwest (had lived in Seattle prior to being “rented” by California for 18 years), I landed in newt territory.

My street is largely undeveloped, leaving plenty of forested critter habitat. A slow-moving creek—dammed by beavers into more of a pond—runs a few hundred meters away, which anchors the local newts. When it rains, especially in fall and spring, we find newts slowly prowling the area. Just as lost keys are more likely to be found under a lamp-post simply because light allows them to be seen, newts are frequently found on streets and driveways because they stand out on such plain surfaces. I suspect it goes deeper than this, in that they also hunt worms, which find their way onto pavement during the rain, and are also perhaps easier for the newts to spot. Rainy time is dinnertime!

I could never have predicted it a few years back, but my wife and I find ourselves smitten by the newts. We love and adore them. I hope this post provides at least a little appreciation as to why.

Life Expectations

Posted on by

A while back, I came across a fascinating paper from 2007 by Gurven and Kaplan on longevity among hunter-gatherers that helped me understand aspects of what life was (and is) like outside of modernity. My interest is both a matter of pure curiosity, and to gain perspective on how desperate life feels—or doesn’t—to members of pre-agricultural (ecological) cultures.

I wrote last year about the perceived perils of early human life in Desperate Odds, in the context that to us members of modernity, having never been weened from the teat of agricultural output, it seems like life without agriculture (and supermarkets) would be a virtual death sentence. Add to this a perceived vulnerability to predation from lions and tigers and bears (oh my!), and the mental image that emerges—as depicted by Daniel Quinn in Ishmael—is of a stressed and starving hunter following the tracks of elusive prey as twilight darkens, while a predator is close on his trail, audibly breathing. It feels like a knife edge of survival: everything has to go just right, but teeters on all going horribly wrong.

The core argument from the Desperate Odds post was that surviving to reproductive age was obviously common, or our species would wink out. This simple fact makes daily survival a near-guarantee—enough so that fear of death is not top-of-mind most of the time, allowing most brain cycles to go toward less-troubled, routine activities.

It was either in preparing that post or in connection with A Lifetime Ago that I ran across the aforementioned paper. In this post, I dig in to see what insights can be gained from survival models for various human cultures.

The Attention-Grabber

Let’s start with the plot that caught my eye and drew me in, which is Figure 3 in the paper.

MM #17: Being Human

Posted on by

This is the seventeenth of 18 installments in the Metastatic Modernity video series (see launch announcement), putting the meta-crisis in perspective as a cancerous disease afflicting humanity and the greater community of life on Earth. Here, I attempt to paint a picture of how we might think of ourselves as humans on this planet, as integral members of the community of life. If we’re good, evolution might keep us for a while—along with lots of friends currently in deep trouble.

As is the custom for the series, I provide a stand-alone companion piece in written form (not a transcript) so that the key ideas may be absorbed by a different channel. The write-up that follows is arranged according to “chapters” in the video, navigable via links in the YouTube description field.

MM #5: Our Biological Inheritance

Posted on by

This is the fifth of 18 installments in the Metastatic Modernity video series (see launch announcement), putting the meta-crisis in perspective as a cancerous disease afflicting humanity and the greater community of life on Earth. This episode extends the point from Episode 3 that we owe almost everything to life that came before us. All our senses and capabilities are inherited. We would be nothing without our older brothers and sisters on this planet.

This is the fourth of about 17 in the Metastatic Modernity video series (see launch announcement), putting the meta-crisis in perspective as a cancerous episode afflicting humanity and the greater community of life on Earth. This episode addresses the more subtle and under-appreciated aspects of evolution, which acts on the whole community of life in full ecological context.

This is the third in the Metastatic Modernity video series of about 17 installments (see launch announcement), putting the meta-crisis in perspective as a cancerous episode afflicting humanity and the greater community of life on Earth. This episode stresses that humans are nothing without the menagerie of single-celled pioneers whose many clever solutions to life we still utterly depend on today.

The Game of Life

Posted on by

Step 400 of the acorn methuselah.  Gliders exit at 12:30 and 5:00.

Despite a lifetime of overlap, and many opportunities to cross paths, I am only now learning of the Game of Life, introduced by John Conway in 1970—the same year that I was introduced to the world. After a few exploratory hours, I knew I’d have to share the insights I gained from it relating to how we react to the present predicament.

What is it that I mean by The Game of Life? Aren’t we all caught up in it? I refer, here, to a zero-player “game” taking place on a two-dimensional grid of square cells (pixels) that can either be alive (on; black) or dead (off; white). Only two simple rules govern whether a cell will live or die in the next time step of the game:

  1. Only “live” squares having two or three adjacent live neighbors (out of 8 possible) survive to the next step.
  2. An empty (“dead”) square having exactly three live neighbors will be “born” into living status on the next step.

The first rule captures a sense of balanced population density: too sparse and survival is hard; too dense and overshoot kills. The second rule is a sexy three-way approach to procreation. Settle down, people.

A surprising degree of complexity emerges from these simple rules, whose deterministic prescription nonetheless leads to essentially unpredictable outcomes. The lessons and parallels to real life—and even breakdowns in the comparison—are highly instructive, I find.
