Stepping back, what can we see?

A One-hour Message

Posted on by

In May of this year, I had the opportunity to give a talk to my department on the matters that concern me. What would I say? How could I pack 20 years of learning, Do the Math writing, and recent perspectives into a one-hour talk for my physics/astrophysics colleagues and for students just beginning their professional journeys? How could I have the biggest impact without coming off as being nuts?

As with many things we do in life, I have mixed feelings about the result: things I should have said; things I could have said differently/better; answers to questions that could have been less clumsy. But overall it seems to have worked. While people were not beating down my door to have further conversations, almost anyone I ran into from the department in the weeks that followed would bring it up—indicating that they had been ruminating on the content and expressing further curiosity. It helps that these are people who have known me for years in another context, but it was still a relief to not simply be dismissed as having veered from the one important path: physics research.

Below is a video capture of the event over a zoom channel. The slides are shown well, but the audio quality varies depending on my movements (could be worse). Questions from the audience are hard to make out. Zoom does amazing things for noise suppression, which also applies to audience reactions (applause, laughter). But hey, you get what you pay for.

The theme of the talk is very similar to that of the shorter video I shared recently. It is also reflected in an article featured in a special sustainability issue of The Physics Teacher in September (below is a PDF of the final paper). So I’m “making a lot of hay” out of this approach, of late.

It has been a while since I posted new written content to Do the Math. I have a backlog of ideas to share, so stay tuned—it’s on the way.

Here We Are

Posted on by

I was asked some months ago by the Australian Foodweb Education organization to participate in their Here We Are project. The idea is to reflect on the statement: “Here we are, alive, at this moment, in this place, together.”

Over the course of several months, I occasionally tried a written-form response, which might later form the basis for a recording. But I was never quite happy with the result—in part because my viewpoint has been rapidly evolving, making it hard to be completely satisfied.

Finally, in April, I felt ready. So I sat on a grassy slope in La Jolla soaking in a chorus of frog song and jotted down bullet points in some semblance of order. I am not talented enough to read a script without it sounding like I’m reading a script, so kept it light. But when I got to my office to make a recording, I wrote the prompt on my whiteboard and realized I could dissect the sentence in a way that captured my perspectives pretty well. I was able to adapt most of the frog-inspired points into something that seems well designed, but in truth emerged rather rapidly.

For my zoom-recorded session background, I chose from the two or three stock images one that both reminds me of the grassy slope where I committed ideas to paper, and fittingly puts me in my place with respect to nature.

Okay—that’s enough backstory. Here is the video recording, and what follows is a relatively faithful transcript, removing a surprising number of “ums” and “you knows,” and patching up a few things with [insertions]. It’s not as polished as a written work, but it is what it is. I did take the liberty of inserting two bits that it pains me not to have included in the recording, which I represent in green font.

The Simple Story of Civilization

The stories we fashion about ourselves are heavily influenced by our short life spans during an age of unprecedented complexity. We humans, it would seem, are unfathomably complicated creatures who defy simple “just-so” characterizations. Animals, or humans tens of thousands of years ago are fair game for simple stories, but not so for transcendent modern humans.

Two major problems I have with this attitude are that 1) we are animals, and 2) we have exactly the same hardware (albeit with slightly smaller brains) as we had 100,000 years ago.

So allow me to pull back from our present age of baffling complexity to outline a simple story covering the broad sweep of the human saga. The result may be a little startling, and, for a number of readers, sure to be rejected by cultural antibodies as “not applicable” (see also my views of our civilization as a cult).

Death by Hockey Sticks

You may be familiar with the term “hockey stick curve,” used describe a trend that has been flat/stable for a very long time, but shoots up at the end of the series in dramatic fashion, resembling the shape of a hockey stick. Hockey can be a violent sport, and it’s easy to get hurt by even one well-aimed swing. Today’s world is being battered from all sides by countless hockey sticks. Mostly, they seem to be targeting Earth’s critters, who are getting bludgeoned unsparingly. But in the end, we’re only harming ourselves.

This post is structured as a gauntlet of hockey stick curves that may leave the reader feeling a bit bruised. Depending on what’s being plotted, many of the graphs shoot up like an exponential, but a few are careening downwards. A theme emerges: the “bads” go up, and the “goods” go down—and not by coincidence.

Human Exceptionalism

For almost two decades now, I have been on a journey to understand what comes next in the grand human enterprise. I started out in a mindset superficially similar to that of most people I encounter—assuming that we would innovate our way into a future that became ever better: less poverty and hunger; greater conveniences; a probable space future—fingers crossed.

But the more I dug into the details, the more concerned I became that such a grand vision is an illusion built on top of a highly anomalous period in human history when we over-exploited finite resources on Earth in a one-time bonanza—using those resources to access remaining resources ever faster in an accelerating cycle. I constantly sought reassurance as to what I had wrong about this picture, but found little solace. Those who tried to ease my mind spoke in vague praise of human capabilities and pointed to the arc of history as a reliable pattern by which to understand the future. I did not get the impression that they had confronted my specific concerns and had a blueprint for how to navigate past the pile-up of global-scale problems and irreversible consumption of our inheritance.

Lately, as I meet other academics (via PLAN) who have come to similar conclusions (sober, deep, and careful thinkers, I find), a frequent question that arises is: how can something that seems so obvious to us be dismissed by so many others? What are we missing? Or what are they missing? Why is it so hard to reach common ground? Where is the disconnect?

An answer—or at least a partial one—is beginning to resolve itself in my head. Previously, I tended to focus on growth and ecological overshoot as the most important “upstream” factors impacting our complex civilization on our road to an uncertain future, while issues like climate change and political/social considerations are downstream effects (symptoms) that will not get solved without first addressing root causes (the underlying disease). But maybe I have stumbled onto something even more foundational—the headwaters (pathogen), if you will—and am starting to pinpoint why our peril is so hard to grasp.
