The unexpected science subtext of George Miller's 3,000 Years of Longing

George Miller’s lavishly produced recent film, “3,000 Years of Longing,” could be described as a sort of Aladdin for adults. It is the retelling of a tale from Scheherazade’s 1,001 Arabian Nights set in our mythology-leary world. And, contrary to expectations, if one digs beneath the surface, a surprising story about science reveals itself.

That science will play a role in this reformulation is hinted at early on in the movie. Alithea Binnie (Tilda Swinton), a “narratologist” by trade, is arriving for a storytelling conference in modern day Istanbul. Her grip on reality is called into question when we watch her spy a diaphanous, gnome-like man trying to run off with her baggage cart at the airport. Unwelcome apparitions like him continue to appear, unbidden, at the conference’s keynote lecture where a distracted Alithea pauses to declare that the tales of gods and heroes of ancient times have been vanquished to the dustbin of history. According to her, scientific explanations now rule the day.

Given Alithea’s job as an expert on the art of storytelling, this declaration is a surprise. Shouldn’t she at least take some professional pride in the enduring power of ancient myth? Or maybe it’s that, as Alithea has grown older, these just-so stories have lost their appeal. Has tragedy in Alithea’s life drained the magic from her world?

Miller and his co-writer/daughter, Augusta Gore, appear to be setting us up for a tale which will pit the rationality of science against the enchantment of the supernatural. So we ready ourselves to have the hard heart of our cynical protagonist softened by an encounter with magical forces. Thankfully, the writers dodge this predictable storyline and, instead, offer us a story in which science and magic become willing collaborators.

So, when Alithea pries open an antique glass bottle purchased at the Istanbul bazaar releasing Djinn (Idris Elba), she is startled, but, surprisingly, not at all disbelieving. Alithea is not so much concerned that she may be losing her mind when Djinn appears as she is that she will, like a sucker, fall victim to his plea for her to get on with the business of making her three wishes. From experience as a scholar of storytelling, Alithea knows that giving in to this temptation will inevitably lead to a less than happy outcome, no matter how carefully she formulates the statement of her desires.

In order to dissolve Alithea’s skepticism, Djinn launches into his three-thousand-year story as a prisoner of an assortment of lamps and flasks. He describes how he came to be “incarcerated” the first time - by King Solomon, no less - as well as the relationships he has had with the mortals who liberated him after that. In the process, we discover that Djinn desperately longs for lasting freedom, and we also learn that he is capable of deep human attachments. Significantly, for our purposes, it is also revealed that Djinn is a being who is made up of electromagnetic waves. In other words,he is a creature of pure light.

Soon after, the role that light will play in the film is underscored by a set of text panels that flash across the screen briefly. This mini powerpoint presentation telegraphs a schematic history of Djinn’s universe which begins with a burst of electromagnetic waves  - let there be light! - and culminates with the emergence of biological compounds and then, presumably, Darwinian evolution. It appears that, whatever Djinn’s status as a supernatural being is, he sees himself as a participant in a world of natural phenomena. Far from being at odds with one another, in this view of the world science and magic are companionable fellow travelers.

But “3,000 Years” is not done with light yet. As Djinn tells his story, we learn that his most recent liberation, sometime in the nineteenth century it appears, was at the hands of Zefir, the young wife of a Turkish merchant. With a nod to “Faust,” Zefir wishes for all the knowledge in the world. What we see flashing across the screen as a result of her request is a high-speed montage of Zefir devouring book after book supplied by Djinn which contain the scientific findings of the age. 

Usually the graphics presented in such a montage are a mess of mathematical nonsense, a lot of random expressions yanked from a high school algebra text. But the equations that appear in the books that Zefir pours over are, in this case, the real deal. They faithfully retrace the development of the theory of electromagnetism that got underway with Michael Faraday’s experiments in the 1830s in London and culminated in the early 1860 with Scottish physicist James Clerk Maxwell’s unification of electrical and magnetic phenomena. Maxwell’s equations, as his system came to be called, was the first unified field theory of modern physics.

This sequence presents us with a tantalizing ambiguity: is Zefir simply reconstructing discoveries reported by contemporary researchers in the books Djinn has provided, or has she, in a stroke of genius, developed a theory of electromagnetic waves all on her own, beating the esteemed Maxwell to the punch? Maybe the famous handful of equations should rightfully be called Zefir’s equations?

This backstory having to do with the phenomena of electricity and magnetism continues into the final act of the film when Alithea returns to London with Djinn as her companion. Creature of light that he is, Djinn is acutely sensitive to the electromagnetic radiation that impinges on him. In fact, he is so overwhelmed by the ocean of radio waves, Wi-Fi, and wireless signals that he starts to become ill. (Admittedly, present-day Istanbul, the technological metropolis that it is, should have presented Djinn with similar problems.) Although he manages to maintain his composure in the face of this electromagnetic assault, it slowly begins taking a toll on his well-being.

At the beginning of the film Alithea telegraphs that a science vs. superstition confrontation may be in the offing. And, yes, Djinn’s composition as a creature of light, along with the electromagnetic origins of the universe, is clearly stated. Yet no review of the film that I’ve read takes note of these facts. In addition, the montage of mathematics including Maxwell’s equations streams by so quickly that it takes a trained eye - at least an eye that has been exposed to an intermediate undergraduate course in electricity and magnetism - to make sense of it. Somehow, though, I doubt that physicists were the intended audience for the film.

A possible explanation is that the writers inserted the Easter eggs having to do with electromagnetism as a message in a bottle of sorts into the encasing tale of Alithea and Djinn. And it could be that they expected the occasional viewer, like me, would pick up this bottle and rub it hard enough to have its hidden message revealed. If that is the case, then I count myself as lucky to have happened across “3,000 Years” and to discover, unexpectedly, the science story inside. Being a science nerd, a wish of mine was indeed granted.

Marching for science – and for culture – on April 22

In the last couple of months, much has been written about the upcoming March for Science to take place here in Atlanta and around the world on April 22. And a lot has been said about what makes science great. But, in my mind, not enough has yet been said about how science makes us great.
I am the executive director of the Atlanta Science Tavern, a grassroots public science forum organized on Meetup.com with over 6,200 members. We produce and promote science-related educational events and activities in the Atlanta area.
In the time that I have led the Science Tavern, the most prized compliment that I have received has been, “your group is one of the things that makes Atlanta a great place to live.” The reason that I like hearing this so much is that it implicitly recognizes that science, like art and music and theater, is an essential part of the cultural fabric of our wonderful city.
Now, I wouldn’t for a second downplay the amazing practical benefits that science has brought us.
  • Vaccination, a resounding public health triumph, has saved hundreds of millions of lives and fought back the timeless scourge of commonplace childhood mortality.
  • The physical sciences, with their mastery of light and matter, have given us the ability to process and communicate vast quantities of information in the blink of an eye, allowing us to form a web of human connection spanning the globe.
  • Scientific investigation of the Earth and its precious atmosphere has made it possible for us to understand the role we play in altering our environment, providing us with guidance on what to do to safeguard the well-being of future generations.
But beyond these many marvelous useful things, science has also served to ennoble us. And it has done so by helping us to cultivate a sense of wonder about ourselves and the world around us.
  • How did the universe grow from a microscopic knot in space-time fourteen billion years ago into the one we now observe, brimming with dark matter and dark energy?
  • Did life on this planet originate, perhaps as Darwin speculated, in a warm little pond, and might we discover that it has arisen elsewhere in our solar system, perhaps beneath the surface of one of the icy moons of Jupiter or Saturn?
  • How did we, around two hundred thousand years ago, come to be the clever, social primate species that we are today, one capable both of acts of heart-lifting compassion and of heart-breaking cruelty?
  • Is it possible for us to explain how the workings of the tens of billions of neurons in the human brain give rise to our inner experience and even to the phenomenon of consciousness itself?
If you think that we can reap the practical benefits of science without the drive of pure, curiosity-driven research, think again; it is the timeless draw of these profound questions that sparked the scientific revolution four hundred years ago, and they are what continues to propel scientific advances of all types to this very day.
Looking at science in this way, namely as an integral part of our culture, helps make sense of much of what we see going on on the political scene. The same forces that are trying to undercut science also have the National Endowment for the Arts and the National Endowment for the Humanities in their crosshairs. Along the way, they intend to eliminate the Corporation for Public Broadcasting and the Institute of Museum and Library Services.
Contrary to what our Philistine opponents believe, we do not live by bread alone – although some among them would deny even that to our schoolchildren. Our human spirit is nourished and elevated by painting and poetry, by music and dance, by theater and film, by philosophy and history, and, of course, by science.
This time around, though, it appears that we will not enjoy the opportunity to speak out as they come for each of us in turn; this time around, they are coming for us all in one fell swoop. So, as we march for science on Earth Day, we must also march for the arts and the humanities and for the libraries and the museums. We must march for all the strands in the glorious tapestry that we call culture. We must march for all these things that make us great.

Why We Fight - For Science

A couple of nights ago, on the edge of the meadow at Piedmont Park, over a convivial dinner that included an appropriate amount of beer and wine, the conversation turned to science - more precisely to how to promote interest in science to the public at large. What, in conventional circles, would have been an unusual dinner-time topic, was an unexceptional one with this group, since we were members of the Atlanta Science Tavern, and we are given to talk about science every chance we get.

Enamored with science. but, somewhat blinded by our adoration, we are sometimes puzzled that others don't share our enthusiasm for the object of our affection. So, when we get together, we often wonder, "how can we encourage our friends to better support and appreciate science?"

A common answer to this question begins with a recitation of the connections between important developments in the history of science and the benefits that have accrued to modern society as a result: the double helix of DNA and cancer-fighting medical diagnosis; quantum physics and high-performance computer chips; genetic engineering and increases in agricultural productivity; Maxwell's theory of electromagnetic waves and near-instantaneous global communications; Newton's orbital mechanics and hurricane tracking. The list goes on and on. It is extraordinarily convincing.

[So as not to whitewash the matter, I readily acknowledge that science has been implicated in its share of failures and catastrophes. On balance, I believe that science comes out ahead in the cost-benefit tally, but some, notably Theodore Kaczynski - better known as the Unabomber - have constructed serious arguments to the contrary. Should, for example, the most dire predictions for global warming be borne out, Ted may well be proven right for his skepticism about technology being an unequivocal force for good, although he should never be excused for the psychotic tactics he used in trying to disrupt its advance.]

Although this kind of utilitarian argument for science is persuasive, I find it, in some respects, disingenuous and, in others, incomplete. It is less than forthright in that it fosters a misconception about why people undertake scientific careers. No doubt there are those who do so motivated primarily by their interest in benefiting mankind, but, in my experience, scientists are, more often than not, driven by an unabashedly self-centered desire to better understand the world in which they live. Public service, although a welcome side effect, is not preeminent among their personal goals. In addition, although arguing for science based on its practical applications may be the strongest hand we have to play in general, the fact of the matter is that many significant fields of scientific research have no chance of bearing technological fruit.



On the morning of the day of the informal Science Tavern dinner the New York Times had published a front-page article announcing the successful reconstruction of a skeleton nicknamed Ardi, the fossil remains of 4.4 million-year-old hominid, and a member of a likely bipedal species which may turn out to be a direct ancestor of our own. To say the least, it would be quite a stretch to come up with a justification for supporting such a masterwork in paleoanthropology based on its potential contribution to our practical technological progress.



I am no stranger, personally, to the rather quixotic pursuits that are part and parcel of basic research. As a graduate student in the late 1970s I worked with a group at the Fermi National Accelerator Laboratory (Fermilab) studying neutrino interactions. Neutrinos are subatomic particles notorious for having little or nothing to do with the real world. Cruising at near the speed of light, they would hardly notice planets placed in their path; the Greta Garbo of elementary particles, after all is said and done, they want to be alone. Consequently, they are seldom considered to be of much practical use, although a once-secret patent was issued for the far-fetched scheme of employing neutrinos to communicate with deep-ocean submarines. Why would anyone pay to study them?

Likewise, what is true about neutrino research in particular is true about the enterprise of elementary particle physics more generally; outside the realm of speculative science-fiction, it is hard to imagine how the knowledge revealed in the course of these investigations into the fundamental structure of matter could lead to anything of practical value. But the value, practical or not, of such basic research is a question we cannot avoid. CERN's Large Hadron Collider (LHC), a Europe-based successor to the accelerator at Fermilab, and the most ambitious instrument yet devised to advance our understanding of the submicroscopic workings of the universe, is scheduled to begin full-fledged operation within a year, at a cost of almost $6 billion. How do we begin to justify such an extravagant expense, given that there is no reasonable prospect of deriving practical benefits from the results that the experiments that will be performed there will produce?

A very similar question had been posed to post-war American researchers, during an era when that country, which had placed a high-stakes wager on the success of the Manhattan Project and had won, was eager to fund the research efforts of the generation of scientists who had participated in the development of the atomic bomb. Robert R. Wilson was not only one of the best of that wartime cohort of physicists, he was also a sculptor, an architect, and the driving force behind the development and construction of Fermilab, as well as its director for a number years, including the brief period that I worked there.

In 1969 Wilson was called before a joint congressional committee on atomic energy to give an accounting as to why the public should continue funding the building of his giant proton accelerator, which, when completed, would measure almost 4 miles in circumference and cost over $250 million, at a time, it should be recalled, when $250 million was a significant line-item in the federal budget.

It was the height of the cold war, and any relationship to military purposes could have been offered by Wilson as an explanation and would have been accepted on the spot. But Wilson, who had been deeply affected by the regret he felt for his work on the atomic bomb and had distanced himself from the defense establishment as a result, did not take this easy way out. Instead, declining to use "national security" as a justification, he said this of his Fermilab project:
It has only to do with the respect with which we regard one another, the dignity of men, our love of culture. It has to do with: Are we good painters, good sculptors, great poets? I mean all the things we really venerate in our country and are patriotic about. It has nothing to do directly with defending our country except to make it worth defending.
Promoting public appreciation of science in this way is much more challenging than appealing to concrete interests based on the expectations of advances, for example, in nutrition or healthcare or transportation or power production or consumer electronics or, in Wilson's case, national defense. But the fact of the matter is that it is the only honest way to argue for public support for many areas of basic research, and often more accurately reflects the motives of those engaged in scientific endeavors. In addition, it serves to reframe the debate about what genuinely constitutes the public interest and expands the conventional definition beyond concrete practical concerns. Ultimately the triumph of our civilization is not only the elevation of our comfort and our security, but also of our culture.

This I Don't Believe

Let's suppose you had the opportunity to interview a judge who had recently published an opinion on an important criminal case, one in which she had found, for purposes of concreteness, in favor of the defendant. Your questions turn to the matter of the judge's objectivity, and then it is revealed that the judge has had a long-standing prior relationship with the accused.

Pressing the issue you ask whether this relationship may have influenced her decision. "No, not at all," she responds. "On the contrary, my acquaintance with the defendant didn't skew my judgment, it helped to inform my decision."

At this point in the interview you may begin to doubt - not necessarily the judge's personal integrity, since she may, after all, have had no untoward interest with regard to the outcome of the case - but her judicial faculties. Does she understand the concept of objectivity well enough to realize that it requires that she distance herself from her prejudices and, most certainly, not rely on them?

Such a failure to appreciate the meaning of objectivity is illustrated in a recent interview with Barbara Bradley Hagerty, NPR reporter and author of the forthcoming book, Fingerprints of God, by Weekend Edition Sunday host Liane Hansen. By virtue her authorship Hagerty has positioned herself as a judge of the question, "is spiritual experience real or a delusion?" Although Hansen broaches the issue that Hagerty's upbringing as a Christian Scientist might have affected her analysis, Hagerty proceeds to insist that, in fact, "Christian Science really helped me with my research."

Hagerty goes on to claim that "Christian Science was about 100 years ahead of its time," based on her dubious equation of Mary Baker Eddy's belief in prayer-healing with the emerging field of mind-body studies called psychoneuroimmunology. In this regard, she succeeds, somehow, in demeaning both religion and science. We would all agree that Christian Science is more than simply a theory about emotional health affecting physical well-being (that was hardly breaking news in the 19th century) and, likewise, we would agree that nowhere do contemporary scientific studies of the human brain presuppose supernatural influences on neurological function.

What is, perhaps, more troubling about the interview, having nothing to do with Hagerty's particular take on the religion-science debate, is that it calls into question whether NPR is adhering to its own professional standards. Specifically, the piece opens with the statement:
The golden rule of journalism decrees that reporters take nothing on faith, back up every story with hard evidence, and question everything. NPR's religion correspondent Barbara Bradley Hagerty kept that rule in mind when she decided to explore the science of spirituality.
This is hardly borne out by the exchange between Hansen and Hagerty that follows.

Is it appropriate for NPR to bestow the imprimatur of objectivity on Hagerty's tendentious opinions about religion and science without criticism? It would be one thing if she had simply endeavored to report on the contemporary scientific understanding of the origins religious experience, but Hagerty goes much further. She concludes in the interview, explicitly, that belief in God is a rational choice. This is a profound, and profoundly contentious, question that should not be presented without challenge.

Indeed, the interview and the 5-part series that it previews, Is This Your Brain on God, could be confused with a promotional campaign for Hagerty's upcoming book. Here NPR's own standing as fair "judge" could be called into question. Is Hagerty's book being featured for its merits or is it, to some extent, receiving the spotlight based on its author's long relationship as a reporter for the news organization? To the extent that Hagerty takes a disputed position on a matter of public importance, isn't it incumbent on NPR to present alternative points-of-view? I'm not sure whether NPR, like the New York Times, has a public editor to consider such concerns, but it would seem that its own journalistic standards would demand such consideration.

Speaking of Faith and of Science

What follows is an unpublished letter I submitted to the New York Times in November 2007 in response to an op-ed piece by Paul Davies, Taking Science on Faith, in which he elaborates a criticism frequently leveled at science, that is that it, too, relies on faith.

Dear Editor,

In drawing an equation between the explanatory capacity of religion and science, Paul Davies concludes that science's "claim to be free of faith is manifestly bogus." Of course the scientific process is based on the assumption of a rational system of physical laws. How else could we talk about the world in any meaningful way? But such an element of faith is hardly theological, as Mr. Davies claims.

When I was a graduate student in physics in the 1970s we were taught to bring extreme skepticism to bear when considering even established physical laws. After all, discoveries of the early 20th century had demonstrated, contrary to all expectation, that measures of space and time depended upon an observer's relative motion and that the ability to determine the position of an object on the microscopic scale was forever shrouded in fundamental uncertainty.

Mr. Davies and other proponents of "separate magisteria" err in supposing that faith - even necessary faith in rational discourse - makes science and religion two of a kind. It isn't an absence of faith that distinguishes science, it is its dogged skepticism that encourages cherished beliefs to be assailed and revised, thus undergirding the development of an increasingly accurate and shared understanding of the physical universe.

Theology, though, is largely immune to such a process. How has our understanding of God been refined in any demonstrable way over the last two or three millennia? What kind of agreement over the nature of a supreme being could ever be reached that would satisfy disputing parties?
