In defense of enlightenment: "science adviser" David Gelernter and the rise of anti-science intellectualism

Consternation rippled across the American scientific community, upon learning that Yale Professor David Gelernter interviewed with (then) president-elect Trump, for the job of White House Science Adviser. Gelernter became a doyen of the remnant conservative intelligencia, for denouncing liberal influence on college campuses. His 2013 book, America-Lite: How Imperial Academia Dismantled Our Culture (and Ushered in the Obamacrats) blames “belligerent leftists” for purported disintegration of patriotism and traditional family values.  

Beyond standard Republican catechisms -- such as Climate Change denial, or opposition to vaccination – Gelernter’s views extend even farther to the right, for example attributing the decline in American culture to “an increasing Jewish presence at top colleges.” (Gelernter himself is Jewish.)

In bizarre irony, Dr. Gelernter’s jeremiads against science have migrated steadily, ever-closer to views espoused by Theodore Kaczynski, the “Unabomber,” whose mailed explosives maimed Gelernter, decades ago. Kaczynski’s new book, The Anti-Tech Revolution: Why and How, asserts many of the same manifesto points, distilling down to a message that Gelernter shares: that our scientific-egalitarian enlightenment must be renounced in favor of much older ways.

Alas, offended communities may characterize this news in manichean terms – as just part of a sweeping War on Science. Take the fate of OSTP. Through resignations, attrition and almost zero replacements, the Trump Administration seems on course to all but wipe out the White House Office of Science and Technology Policy, sending it down the path of extinction that — in 1995 — swallowed the congressional Office of Technology Assessment, when Newt Gingrich ruled OTA to be irreparably “partisan.” (As - apparently - are 'facts.')

Now members of Mr. Trump’s circle have called for eliminating OSTP, altogether. In part this is reflex reaction to the way Barack Obama boosted science across the board, more than doubling OSTP and bringing most of its staff into the Executive Office Building, on the White House Grounds. (I gave two presentations there, in 2016, about 'Wider Perspectives on Threat; exactly the use that a nation might make of hard science fiction.)  



(ADDENDUM: This article offers much more detail on the White House Science Adviser office, first officially established by President Eisenhower, offering a partial list of responsibilities. "Manage NASA strategy and budget. Work with the Office of Management and Budget on federal research and development investments. Deal with climate change, both in terms of mitigating it and diffusing the controversy. Testify before Congress. Oversee the National Science Foundation. Execute whatever the classified work on national security and homeland security might be. Forge science and technology cooperation agreements with nations like Brazil, China, India, Russia, and Korea. Support the State Department on other science-related initiatives. Put the president in contact with top outside experts when necessary. All in all, (Obama Science Adviser John) Holdren worked in approximately 70 different science fields at any given time." Even when the office was demoted, under George W. Bush, the WHSA - Jack Marburger - was a prestigious scientist who remained in a science-unfriendly administration because of crucial roles in the National Security Council -- roles that are now, under Trump, deliberately left unfilled.)

At another level, all of this was to be expected. Indeed, when you tally professions on the alt-right’s enemies list – from journalism, medicine, economics, teaching and law to civil servants -- and now  the 'deep state' intelligence/military officer corps – an ironic effect is to make us shrug in resignation.

But in this particular case, shrugging may be premature. There are still corners of that movement that will react to light. So, let's shine some on a fellow who may soon become emblematic of our peril.

First some context: our revolution called progress

Across time, the very notion of human advancement has evoked powerful cross-currents. Pericles, the sage of Athenian democracy, extolled how steady improvements in both wisdom and daily life can occur when free citizens build on each others’ goodness and innovations, while openly critiquing or canceling each others’ crimes or mistakes – an early expression of faith in a positive-sum society.  In sharp contrast, Plato condemned openness and democracy, calling for a self-proclaimed elite to paternalistically protect gullible masses from dangerous ideas.

This battle between visionaries and curmudgeons accelerated when technology become a chief agent of disruptive change, starting with glass lenses and printing presses that prosthetically expanded what human beings could both see and know. With each expansion of sight and knowledge, grouches gloomily forecast a worsening of hatred, chaos and war, prophecies that nearly always came bitterly true – in the short term. Over the long run though, optimists proved more accurate, as books and literacy allowed ever-greater populations to sympathize with faraway cultures and peoples.

We’ve seen the same pattern with successive expansions of perception and memory – from newspapers and radio to television and the Internet. Each knowledge revolution at-first fostered abuse by demagogues, followed later by enlargement of citizenship and empathy, as average folk adapted to drinking information from an exponentiating fire-hose.

This historical perspective is badly needed as we see the very same dynamic emerging yet again, first in wildly un-accountable social media trolling, then an unfolding 21^st Century knowledge mesh and the looming prospect of artificial intelligence, or AI. This prospect rouses the same array of gloom merchants and dizzy romantics, issuing either dire lamentations or proclamations of utopian transcendence. The latter personality, typified by singularity-promoter and immortality evangelist Ray Kurzweil, certainly weaves a fascinating spell, predicting confidently that we’ll soon – within decades – attain godlike powers and satisfactions. But I’ll not spend any time on them, today…

… because, as always, cynics seem more compelling in the short term. For one thing, they often do point at needful warnings! Dyspeptic Jonahs are at their best when calling out failure modes to examine and then prevent. 

Alas, pessimists become a failure mode, perhaps one of the worst, when they undermine the confidence of a can-do, problem-solving civilization. That, indeed, is the only failure mode I truly fear. And so much for context.

Burgeoning attacks upon science

Anti-scientific sentiment appears to be rife at both ends of the hoary-clichéd and lobotomizing "left-right axis," with campus post-modernism representing one, sinister wing. 

Still, you would have to be hibernating to miss the far more copious torrents of hostility pouring at science from the other end. Take, for example, Tides of Mind, David Gelernter’s book that posed an interesting, if simplistic model of human consciousness, while riffing hostility toward a purportedly close-minded scientific establishment. This caused me to revisit his core manifesto, "The Closing of the Scientific Mind," an essay that appeared in the first 2014 issue of Commentary Magazine.  

The title is an homage to The Closing of the American Mind, a 1987 book by Allan Bloom, that once served as a central declaration of the New American Right. Bloom's earlier tome foretold that the United States -- and Western Civilization -- would soon tumble into heck and darnation if the scientific mind-set were allowed to (among other modernist crimes) ruin the subjective-conservative-humanism of impressionable youth. Carrying on with that Spenglerian theme, David Gelernter proceeded to denounce scientific modernity and nearly all its mental works.

To be clear, this was not always his message. Mr. Gelernter's 1993 book Mirror Worlds forecast a coming era when Big Data models will replicate objective reality so closely that cyber and physical may merge in useful ways, empowering us all – a rosy view of technological change that not only put him in the transcendental-optimist camp, but earned him devastating attention from the Unabomber. 

Whether or not that painful, crippling brush with a luddite lunatic was precipitating, Gelernter soon shifted his emphasis increasingly to nostalgia and exceptionalism in tomes like Americanism: The Fourth Great Western Religion, striving to justify the brief reign of Straussian neo-conservatism -- a fervently messianic belief that America could transform other peoples and nations into enlightenment-republicans almost overnight, by sheer, overwhelming force of our unstoppable will.

When that manic phase proved calamitous in Iraq and Afghanistan -- and Straussian neocons went politically extinct -- Gelernter then helped swing the American Right into its later, bipolar cycle of apocalyptic depression. From frenetic imperial activity to a grumbling determination that government should do nothing at all. Doomcasting in the mode of Allan Bloom, Gelernter zeroed in upon a national intelligencia that had been skeptical of both those frantic, Bushite wars and the ensuing melancholia. His book America Lite is a growling dismissal of U.S. universities – which are, ironically, the nation's one realm of completely unambiguous superiority in a fast-changing world.

Irony, alas, appears to escape many of those who engage in intellectual finger-wagging. For example: Gelernter sings paeans to the Greatest Generation (GG) of the 1930s, 1940s and 1950s, who endured a Depression, defeated Hitler, contained Stalinism, spurred entrepreneurial enterprise, erected vast infrastructure, began the work of fighting prejudice, went to the Moon and built the unprecedented American middle class. He touts especially their intellectual honesty and prowess -- while expressing contempt for the world and nation that generation built, along with every political and social edifice they created. 

He also neglects to mention that the favorite living human of that admirable American generation was Franklin Delano Roosevelt. Further, by deriding every value of the succeeding -- boomer -- generation, does not he (and confederates like Steve Bannon) hammer GGs with the worst insult of all? That the GGs were bad parents?

But all of that is prelude. As illustrated in his 2014 Commentary piece, Mr. Gelernter's main denunciations focus on science – or rather the elite and deceitful priesthood that (he claims) science has become.

This isn’t new, of course. Lamentations against modernity and scientific thinking erupt with rhythmic regularity, not just from centers of scholastic nostalgia on the right but also with eerie similarity from the very-far-left, whose scoldings differ only in detailed specifics, not tone.  They call to mind C. P. Snow's famous "Two Cultures" essay that rocked academia 50 years ago. Snow portrayed simmering resentment in some university departments toward scientists, who the humanities dons viewed as usurping their authority over matters of "Truth."  (And note that this divide is completely orthogonal to the usual, left-right measuring rod.)

Although Dr. Gelernter is a computer engineer, his apologia in Commentary reiterates Snow's divide:  "Scientists have acquired the power to impress and intimidate every time they open their mouths, and it is their responsibility to keep this power in mind no matter what they say or do. Too many have forgotten their obligation to approach with due respect the scholarly, artistic, religious, humanistic work that has always been mankind’s main spiritual support." 

Wow. We could discuss those assertions and assumptions all day -- for example by probing whether classical Romans, or post-Alexandrian Hellenistics, or medieval scholastics were ever mass-effective at preaching an admirable life. Or whether any scientist has ever sought to "impress and intimidate" as heavy-handedly as nearly all kings and priests and scholarly pedants did, in times past. But never mind. Mr. Gelernter then veers away from the provocatively interesting, to the absurd.

"Scientists are (on average) no more likely to understand this work than the man in the street is to understand quantum physics."

To which, I am behooved to put it plain. That constitutes one of the most profoundly and demonstrably counter-factual assertions I have seen in years. Pick almost any scientist, almost at random, and this calumny will collapse, as she or he displays far greater than average knowledge of art, literature or history. Indeed, nearly all first rate scientists have artistic or humanistic pastimes that they pursue at almost professional levels. C. P. Snow’s two-cultures divide was never symmetrical.

But let's not linger there; David Gelernter goes on to construct one accusatory strawman after another while accepting no burden of proof. No wonder he sings the praises of subjectivity. In fairness, do go and give his missive a slow and attentive read. I'll wait right here. 

The ancient, dismal, underlying premise

What ultimately underlies Mr. Gelernter's rant in Commentary, and indeed, similar railings against modernity by Francis Fukayama and other Bush Era court intellectuals, is something called Zero-Sum thinking -- the dispiriting belief that if a person has superior powers in one realm, that plus must be paid for with a minus of inferiority in some other aspect of human life. This underlies strange and unsupported assumptions, e.g. that success automatically makes one shallow, or that suffering inherently ennobles.

In promoting this ancient reflex, Mr. Gelernter channels the jealous snarkiness of Walt Whitman's poem: "When I Heard the Learn'd Astronomer" -- implying that boffins who peer through telescopes or understand Maxwell's Equations -- the language God spoke when he said "let there be light" -- cannot, thereupon, ever grasp the beauty of a rainbow, or experience compassion, or have soul.  This compulsion isn't rare. Indeed, zero-sum thinking tugs naturally at us all; it was the common human reflex that dominated almost every past human culture... though not our own.  

Our enlightenment civilization is the only one ever to have been based firmly on the notion of positive sums - that we can be many. That each success does not require a compensating failure. That each winner does not always have to stand upon a smoldering loser. That we might become greater than our parents, as the best of them would have wanted us to be, and then see our children excel far beyond us. That a person who has been lucky and comfortable can still feel the pain of others (it's called empathy). And that limitations on the breadth and depth of human reach are mere impediments, not immutable law.

No greater proof is needed than us. We live in a world filled with spectacular positive-sum results, where most children no longer grow up steeped in tragedy, but with some likelihood that they might leverage their talents, uplifting themselves and others too. That easily-supported and statistically proved assertion is not a call for Pollyanna-complacence. Rather, all of our tentative progress constitutes an urgent clarion summons to complete the partly-fulfilled Enlightenment Promise. Indeed, we judge ourselves and our society harshly in proportion to how far short of that ideal we still lag, proving how embedded the ideal has become, in our hearts.

Moreover, scientists lead the way.  For every bad thing science engenders (and most-often scientists issue the alerts), there are a hundred genuine advances. 

When cliché becomes outright slander

May I be forgiven for reiterating a central point? Anyone who has spent time around top-level scientists knows that they tend (with some exceptions) to be profoundly broad in their interests. Most are well-read and thoughtful far beyond the so-called "objective" realms. At three years old, I was privileged to watch Albert Einstein perform with his violin. As an undergraduate, I got to discuss patterns of history and humanism with physics Nobelist Murray Gell-mann, before we shifted to Joyce's “Finnegan's Wake.” Richard Feynman was among the world's greatest bongo players; he also painted brilliantly and wrote passionately about humanity's need to combine bold exploration with humility before a stunning cosmos. (And he stole my date once, at a Caltech dance.) Lynn Margulis showed us how to view our planet as a living entity. The anthropological insights of Sarah Blaffer Hrdy challenged smug dogmas of both left and right, showing how we are simultaneously rooted in our ancestral past and profoundly launched far beyond it all.

Perhaps Professor Gelernter has never spoken with such people, or else he is deliberately spreading a known calumny. Either possibility is both troubling and deeply discrediting for a person who would presume to give guidance to the mighty. 

Specifically, almost no modern scientist declares the non-existence of subjectivity or its irrelevance to human life, despite Dr. Gelernter’s claim that most do. That scarecrow accusation is a dodo based on 1960s fads of Logical Positivism and Skinnerism – which were minority views even then -- an obsolete libel that is only raised by postmodernists of the far-left and right, clutching justifications for resentment.

Likewise, David Gelernter condemns a purported scientific fixation that our human minds are mere software - a position taken literally by only a few researchers in artificial intelligence. Many scientists who ponder deeply about Artificial Intelligence – for example Christof Koch, director of Seattle’s Allen Brain Institute, or the cosmologist Andre Linde -- reject the mind-as-purely-software model. Most apply the comparison only as a metaphor, expedient for generating experiments and models, contingently useful, with exactly the tentativeness and humility that Gelernter claims technical people lack. Which makes me doubt that this "computer scientist" gets out very much.

 Indeed, I need only use two words to cast hilarity upon David Gelernter's absurd strawman. Those two words are --

… Roger Penrose…

… whose fabulous speculations about the specialness of human consciousness run diametrically opposite to Gelernter's stereotype, yet are backed by one of the most brilliant -- and cantankerously contrarian -- physicists of our age.  A personality trait that is, in fact, prevalent among the best scientific minds.

Bridging the "cultures"

Where do I come into all this talk of human beings -- individuals, groups and a rising civilization -- bridging the gap between C. P. Snow's Two Cultures? I speak as a scientist and engineer who makes most of his living writing novels that weave vivid subjective realms for readers to roam, exploring everything from interstellar flight to what it might feel like to be a speaking-sapient dolphin, or an autistic person who has been empowered by new tools to take on the world. Like Sagan, Asimov, LeGuin and Clarke, I aim to blend science with artistically-conveyed empathy. 

As we do at UCSD -- in America's lower left corner -- where every academic department signed on to help establish the Arthur C. Clarke Center for Human Imagination, a cross-disciplinary collaboration combining everything from neuroscience to modern dance, in Arthur's polymath tradition. Pure proof that Snow's dream of a healed divide can come true. 

But coming back to "The Closing of the Scientific Mind," I confess that my attention started to flag as David Gelernter continued flailing at statues made of hay, slinging one counter-factual assertion after another, bereft of citation, evidence or even illustrating anecdotes, tempting this scientist-artist-humanist to paraphrase the classic womanly-chiding: "Hey! My eyes are way over here. And so is the rest of me." 

Still, in an essay rife with fabulations, this one near the end truly took the cake:

"Science needs reasoned argument and constant skepticism and open-mindedness. But our leading universities have dedicated themselves to stamping them out…" 

Shades of Allan Bloom! But in fact, across the vast and tragic history of our species, no human field ever taught those skills as sincerely and relentlessly as science. Each day scientists – the most competitive human beings our species ever produced – go at each other in a spirited tussle, ever-searching for each others’ errors, with ferocity and transparency and sportsmanship that would make any athletic league proud. And when – anecdotally – those standards lapse, it is always other scientists who bring it to light.

In other words, David Gelernter's diametrically opposite-to-fact assertions are worthy of Orwell's Ministry of Truth.  Indeed, it is his warped view of science and its practitioners that makes the prospect frightening, how close he might stand to the elbows of the mighty.

If civilization has recently advanced against a myriad ancient crimes like racism, sexism and environmental neglect, it is because science taught us how to refute and cast down comfortable prejudices that all of our ancestors – including each era's scholastics, priests and "humanist" scholars -- took for granted. Preaching didn’t end those horrid, subjective excuses to waste human talent. It was relentless, scientific disproof of stereotypes about women, minorities and so on, that finally overcame the dismal, filthy habit of blanketing entire groups with slander…

…the way David Gelernter attempts (laughably) to blanket libelous slurs across the one field of human life that keeps insatiably asking questions. The one habit that he clearly fears.

One final example

Let me conclude by offering an even better refutation. I invite you to acquire and watch Jacob Bronowski's "The Ascent of Man," the groundbreaking 1970s television show that led to Carl Sagan's Cosmos and so many other joyous celebrations of a great irony -- that science is simultaneously cheerfully youthful and soberly mature, eager to challenge all limitations, to construct ever-better world-models, and yet always aware that every theory is imperfect. 

See especially Bronowski's episode "Knowledge or Certainty," in which he shows how much interplay there is between science and the arts/humanities.  How science, unlike any other "priestly" system, never claims and never can claim perfect knowledge. Amid its greatest triumphs, science reminds us that our models of the world are always contingent, improvable, and perpetually fringed with a chastening aura of uncertainty.

It is in this combination of adolescent-voracious curiosity and perpetual humility that humanity's ascent continues, by climbing out of the pit of monstrous certainty that infested and infected most dogmatic systems of the past.  Indeed, this cheerful sense of contingency is the trait of science -- far more than all of its accomplishments and power -- that most unsettles and terrifies those wanting some zero-sum absolute to cling-to.

It is in the dismal trap of platonic essences -- with their declarations of derived or heavenly or scholastic certainty -- that hell truly resides.

David appears frequently on shows such as Nova and The Universe and Life After People, speaking about science and future trends. His non-fiction book -- TheTransparent Society: Will Technology Make Us Choose Between Freedom and Privacy? -- won the Freedom of Speech Award of the American Library Association.   

Science wonders... and nonsense...

We'll do a weekend science roundup with some interesting twists.  First...

Are black holes quantum computers?  Might the mega-sun black hole at the center of our galaxy be an uber quantum engine, actually operating on whatever information falls into it?  This physicist thinks that gravitons may thread across the event horizon, providing the ‘hair’ that John Wheeler claimed Black Holes cannot have.  They do this by forming a critical Bose-Einstein condensate… or so a new model suggests, and the insight may open up yet another approach to designing quantum computers.  Now the bigger question… is that where THIS simulation is currently being run?

Speaking of great computers… MacObserver runs an interesting podcast interesting interview podcast series.  This one with yours truly covers a wide range, from my education at Caltech and UCSD to how I got drawn over to the Dark Side -- arts like fiction. Also where some of us hard science fiction authors imagine "things" heading. And why the stars are our destination. (Oh also, some talk about Apple stuff!)

== Skewering BOTH left and right, in turn ==

Fans of the “Sokal Spoof” recall that episode when a post-modernist semiotics journal was fooled into publishing a deliberately nonsensical philosophical paper filled with dazzlingly meaningless jargon… similar to most of the serious articles in that region of “scholarship.” The desperation for relevance in the very-far-left in academia was exacerbated by both the collapse of communism and the ever-accelerating successes of western science. Jealousy toward the latter, especially.

But the thing they fear most deeply is the modern trend toward cross-disciplinary breadth – that many in the sciences and arts are now happily talking to each other, even collaborating, demolishing the old (C.P. Snow) notion of Two (mutually incomprehensible) academic Cultures. (See how we are doing this at UCSD's new Arthur C. Clarke Center for Human Imagination, where the sciences and arts come together to explore humanity's most unique gift.)

Since this undermines their whole premise of smug dismissal of scientists as narrowminded, specialized oppressor-boffins, the trend has led remaining postmodernists to double-down, ironically diving down a rabbit hole of fetishistic obscurantism and stylistically-despondent elitism, wherein the greatest fear is to be comprehensible (and thus criticized) by minds outside their own priestly curia.

Okay, take a breath after that paragraph!  Then hop over to see how this mania keeps exposing the cult to well-deserved ridicule as sokal-type hoaxes keep snaring the editors of obscurantist journals like “Badious Studies.”

Oh, but the weirdo campus left - while it contains some subjectivist bullies - does not compare to the madness on today's right, which now consists of lunacy. For example: here’s why you can no longer find scientists - or any other knowledge profession, from law or medicine to journalism to you-name-an-exception - affiliating with the GOP or allied parties around the world. In Australia, the openly stated goal is to slash the Oceans and Atmospheres division of the national research agency by 120 positions specifically so that there will be ‘no further study or monitoring of climate change.’  Moreover, this aim is specifically, baldly and proudly and openly stated. During an era of severe and growing drought, while most of Australia's population lives right by the coast, at sea level. And that level will rise.

 Truth is inconvenient to the coal barons who currently own Australia… and those who have for generations sought to own America. Scientific evidence has mounted far beyond reasonable proof. So what are the cult leaders to do? Get the cultist-drones to look away!  Look away.  Look away. Lookaway lookaway lookaway ….

As we fret about climate change, the good news is that despite near-treasonous obstruction, technologies for both vastly improved energy efficiency and non-carbon generation seem now to be unstoppable. Creative and scientific folks are winning that fight, irreversibly. Moreover the Paris accords seem headed toward a sign-on by almost every nation on Earth, showing some real potential for major policy action, if the U.S. can rouse itself from political mania and show real leadership.

But soon enough?  As atmospheric carbon continues to build, there remains a lurking possibility that the good  trends will be outraced by the momentum already built into global warming.  For example, if a tipping point is reached that triggers release of gigatons of methane now sealed in Clathrate Hydrate ices along the ocean floor.  That powerful greenhouse gas could send the atmosphere into a runaway.  (See descriptions of the “clathrate gun.”)

If a tipping point seems near, then we’ll have no choice but to attempt palliative measures… such as Geoengineering.  Yes, horrifically politically incorrect!  And some of the proposed methods are… well… unwise on the face of it, like spewing sulfurous gases into the Stratosphere.  I favor research into the method that I portrayed in EARTH (1989) -- (one of the early sci fi books partly about a warming crisis) -- a method that mimics the planet’s own recovery system, stirring ocean bottoms in strategic locales to replicate exactly the method Mother Nature uses to create the great fisheries off Chile and the Grand Banks.  What could go wrong? No, I mean that question seriously. You tell me what could go wrong. You got nothing.

Now to the new item I just learned about: “The Azolla event occurred in the middle Eocene epoch, around 49 million years ago, when blooms of the freshwater fern Azolla are thought to have happened in the Arctic Ocean. As they sank to the stagnant sea floor, they were incorporated into the sediment; the resulting draw-down of carbon dioxide has been speculated to have helped transform the planet from a "greenhouse Earth" state, hot enough for turtles and palm trees to prosper at the poles, to the cooler, more temperate period that followed..”  Huh! Ferns. To the rescue?

Consuming fructose, a sugar that's common in the Western diet, alters hundreds of genes that may be linked to many diseases, life scientists report. However, they discovered good news as well: an important omega-3 fatty acid known as DHA seems to reverse the harmful changes produced by fructose.  

Scientists are making some progress in learning how to manipulate the microbiome, a realm that I predict will bring the 21^st Century’s first truly major medical transformations – because the array of bacteria living within us, while large and complex, is inherently linear and ought to be well-correlated, soon, with genes, body types, diet and lifestyle. Already there are pushes to alter many longstanding practices, as described in Missing Microbes: How the Overuse of Antibiotics Is Fueling Our Modern Plagues, by Martin J. Blaser, M.D.

See also “Why Are Your Gut Microbes Different From Mine?”  from The Atlantic.

Add another biometric that will give you away, no matter how cleverly encrypto-techie you are about masking your identity: Binghamton University scientist Sarah Laszlo talks in another interview about an experiment which suggests that biometric "brainprints" could replace fingerprints in the future. Her new study shows that people can be identified "with 100 percent accuracy" using only brain waves.  “Brainprints may carry some potential advantages over fingerprints in identifying people. For instance, if a person’s fingerprint is stolen, there’s virtually nothing that can be done because fingerprints are “non-cancellable,” Laszlo said.   “Brainprints, on the other hand, are potentially cancellable,” she said. “So, in the unlikely event that attackers were actually able to steal a brainprint from an authorized user, the authorized user could then ‘reset’ their brainprint.””  

How did humanity pay the energy costs of our giant brains?  Well, there were some newly discovered efficiencies – our two legged gait is slow and difficult to master, but also extremely efficient. But now researchers know that our solution was simply to pay the difference.  They found that “that after adjusting for size, the humans were burning 400 more calories every day than the chimps and bonobos, 635 more than the gorillas, and 820 more than the orangutans.” And hence many of our innovations involved ways to get the extra food. Sharing food resources and divided roles for hunting and gathering, for example, as well as cooking to free up more calories for less digestive work. Then putting that massive brain to work in other ways. 

A fascinating talk on the Long Now site describes how much more energy and water efficient “C4” plants like corn are compared to C3 crops like rice, the staple food for half the world. If rice can be converted to C₄ photosynthesis, its yield would increase by 50% while using half the water. It would also be drought-resistant and need far less fertilizer. This plant biologist is part of an effort to refine perhaps as few as a dozen genes that might accomplish such a wonder in perhaps 20 years.  

Wow… so cool rotating depictions of viral shapes and surfaces in Virus Trading Cards.

Quantum Water?  “No, not some sort of New Age stuff that Deepak Chopra would drink," but quantum tunneling of individual water molecules in 5Å channels of beryl crystals. "This means that the oxygen and hydrogen atoms of the water molecule are 'delocalized' and therefore simultaneously present in all six symmetrically equivalent positions in the channel at the same time. It's one of those phenomena that only occur in quantum mechanics and has no parallel in our everyday experience."

Myths about earthquakes abound. For example that “big-ones” offer the biggest danger. Only one earthquake larger than magnitude 8.0 is on the list of the 16 deadliest earthquakes; about one-third had magnitudes of less than 7.5. Each year, on average, there are one or two quakes bigger than magnitude 8; 15 bigger than 7; about 150 bigger than 6; and so on.

Sperm whales. Among the most fascinating creatures ever, on this planet.  This article (accompanied by an amazing photo) describes researchers who free dive with these titans, correlating sonar expressions with behaviors:

“When their clicks are viewed on a spectrogram, a visual representation of an audio signal, each reveals a remarkably complex pattern. Inside these clicks are a series of shorter clicks, each lasting a few thousandths of a second, and so on.Mr. Schnöller and Mr. Buyle believe that sonar artifacts (like images) might be embedded in these vocalizations — that because these animals are already viewing their world through echoes, they may also be able to send these echoed images to one another. They’ll test the theory by capturing these clicks, sending them back to the animals.”  (Might I add that this notion of communicating via sound-sculpted imagery was in both Sundiver and Startide Rising?)

The Corrosion Resistant Aerial Covert Unmanned Nautical System - or CRACUNS - is a submersible UAV that can be launched from a fixed position underwater, or from an unmanned underwater vehicle (UUV). It can stay on station beneath the water, then launch into the air to perform a variety of missions.

Metal foams can be reshaped to make wings that reconfigure in action or allow a submersible to change into an aircraft? Oh, and they offer armor and anti-radiation protection, too.  

From Cape Town, filmmaker Sven Harding looks at how the city's forgotten underground tunnels could help it tackle its drought problem.

Finally, a bit of fun...

Suppose you could bring historic figures forward in time? Could they adapt? Ben Franklin certainly! He'd never drive a car but would soon host a talk-show. Adam Smith? He's already up and running the Evonomics site, filled with weekly insights about how we can save creative market enterprise from its age-old enemy, that Smith despised - oligarchy. 

The time-snatch notion -grabbing histoical figures - is one I played with in a draft novel, long before Sundiver, and the ideas are still cool. But to see it done with some low brow humor, see the podcast show “Great Minds with Dan Harmon.”  See them snatch up Sigmund Freud and Idi Amin. And of course, then, there was Bill & Ted.  Anybody else miss 'em?

The old and new versions of "culture war"

This month, we note the 50th Anniversary of C.P. Snow's famous Rede Lecture, "The Two Cultures," which described the wide and seemingly unbridgeable gulf of language, assumptions and mindset, between people working in the sciences and intellectuals in the literary arts and humanities.  In a a followup essay, "The Two Cultures: A Second Look," Snow optimistically suggested that a new culture, a "third culture," might emerge and close the communications gap. In Snow's third culture, the literary intellectuals would be on speaking terms with the scientists.

According to sci-tech book agent John Brockman ”This never happened. Although I borrowed Snow's phrase in my 1991 essay "The Third Culture", it does not describe the third culture he predicted.”   Indeed, Brockman portrays recent progress as more one-sided than any act of collaboration, with the bridging largely undertaken from the scientific side and most literary mavens playing the unhelpful role of cantankerous curmudgeons. 

”The third culture consists of those scientists and other thinkers in the empirical world who, through their work and expository writing, are taking the place of the traditional intellectual in rendering visible the deeper meanings of our lives, redefining who and what we are. Increasingly, The Third Culture has moved into the mainstream and the questions it is asking are those that inform us about ourselves and the world around us.”

Speaking as someone who has moved across both of these worlds without impediment, all my life, I can say that Brockman is mostly right about this.  High-end scientists do tend to be vastly more agile and forward-looking thinkers, than their counterparts in almost any other field of endeavor.  Instead of narrowly-specialized “boffins,” those at the top of their fields seem to be smarter, more-broadminded and deeply curious than anyone else alive. The reason for this is so astonishingly simple that it seems to have escaped notice.  It has nothing to do with any intrinsic superiority of scientific minds.  Rather, suppose that a person is truly broadminded and eclectic, wanting to excel in a wide span of fields. He or she must thereupon choose the scientific field of interest to work hardest in, at the professional level, simply because science is exceptionally demanding.  That person's other interests, in contrast, can be pursued part-time.   Indeed, nearly all of the top scientists I’ve met (and I know many) also nurtured impressive artistic hobbies and passionate avocations, at near-professional levels.  They bridge the gap not as invaders from science but as brilliant people who never accepted the existence of any gap, in the first place!

Meanwhile, the intellectual curse of vapid, simpleminded postmodernism has been slow to dissipate from hundreds of university English, Literature and social studies departments.  One symptom of this obdurate troglodytism has been the refusal of all but a dozen U.S. universities to pay more than nodding attention to science fiction, the most exploratory and truly American of all genres.  Another diagnosable illness is the slavish devotion that so many have pledged to the rigid storytelling tropes that Joseph Campbell called “fundamental” to myth.  These rigid prescriptions may have been nearly ubiquitous for 4,000 years, but nobody seems willing to also point out the downside -- that those bardic straightjackets were also fundamentally debasing of the human imagination, helping to limit and crush our shared cultural experience... until we finally broke free of our chains.

And yet, having agreed with much of Brockman’s point, I do have to take some exception.  Because the literary types that he and Snow call the “first culture” are not really relevant to the intellectual problems of our age. Self-marginalized and generally silly, the literature profs are no more pertinent for their anti-science thetoric than they ever were a threat to young minds, by promoting “leftist memes.”  These were strawman foes, hardly even worth the time spent shrugging them off.

Then why talk about this cultural gap at all?  C.P. Snow had an excuse.  Especially in his day, the British education system was in large part designed to cauterize scientific or technical “boffins,” keeping them physically and intellectually isolated while ensuring that real power -- cabinet posts , corporate directorships and such -- would be preserved for those steeped in the classics. (Whereupon, completely subjective grading ensured that the sons of aristocracy would slip gracefully into the high positions set aside for them.)  Hence a nearly complete lack of “breadth requirements” in most British (indeed, European) baccalaureate programs.

Meanwhile, U.S. students take an extra fourth year longer for their bachelor’s degree, getting exposure across lateral horizons of interest.  This important feature of American academic life is seldom mentioned, even though it is an inherent expression of a very different intellectual worldview.

Hence, while American lit departments are only slowly awakening from their prickly, faux-European inferiority complex, others on campus have no problem embracing a new culture of change. At the University of California, San Diego (UCSD), for example, several arts departments have joined with scientific colleagues to forge Sixth College, and the Center for the Study of Computing in the Arts, dedicated to the mission of bridging every perceived gap, with tech-savvy artists and art-loving techies.

No, in America the dangerous gap is not between CP Snow’s old archetype intellectual cultures.  Rather, what we are challenged by is a very different “culture war,” in which every kind of anti-intellectualism is fanned by those who most directly benefit from this put-up distraction.  One of the tools that help to maintain this debilitating chasm?  The metaphor of an obsolete and profoundly misleading, so-called “left-right political axis” -- a curse from 18th Century France that has been a lobotomizing political discourse for generations, focusing attention on a silly, almost meaningless “gap,” when the real chasm is much simpler -- between non-thieves and thieves.

Want to attend Worldcon? The World Science Fiction Convention is always a marvelous show and this year's event Anticipation -- in Montreal, city of fine food and hospitality -- should prove no exception with great panels, previews, the Hugo Awards and a special min-conference on teaching science fiction in the classroom that I labored to help create, along with the fine folks at www.AboutSF and Reading for the Future.

 So cool In case you haven't already seen it -- the launch of a 1/10-scale model of a Saturn V rocket, built by hobbyists. I'd have been impressed if it used liquid hydrogen and multi stages.

 ELECTROMAGNETIC pulse weapons capable of frying the electronics in civil airliners can be built using information and components available on the net, warn counter-terrorism analysts. Yael Shahar, director of the International Institute for Counter-Terrorism in Herzliya, Israel, and her colleagues have analysed electromagnetic weapons in development or used by military forces worldwide, and have discovered that there is low-cost equipment available online that can act in similar ways. "These will become more of a threat as the electromagnetic weapons technology matures," she says.  Douglas Beason, a director at the Los Alamos National Laboratory in New Mexico, says it may be straightforward to build a do-it-yourself EMP weapon, but more difficult to make one that can be stowed in an aircraft. 

 BTW - Beason is a Brin-pal. See my own suggested measure we should take, in order to solve this threat.

VisionCare Ophthalmic Technologies has developed a miniature telephoto lens that can be implanted into the eye and could soon help people with vision loss from end-stage macular degeneration. (VisionCare) Because only the central parts of the retina are damaged in the disease, magnifying the image on the eye allows the retinal cells. 

 Chris Phoenix of the Center for Responsible Nanotechnology: ”I learned about research that is nearing completion to develop a strain of E. coli which cannot be infected by bacteriophages.  Phages are a major mechanism - likely *the* major mechanism - that keeps bacteria from growing out of control. A phage-proof bacterium might behave very similarly to "red tide" algae blooms, which apparently happen when an algae strain is transported away from its specialized parasites. But E. coli is capable of living in a wide range of environments, including soil, fresh water, and anaerobic conditions.  A virus-proof version, with perhaps 50% lower mortality, and (over time) less metabolic load from shedding virus defenses that are no longer needed, might thrive in many conditions where it currently only survives. The researchers doing this acknowledge the theoretical risk that some bacteria might become invasive, but they don't seem to be taking anywhere near the appropriate level of precaution. They are one gene deletion away from creating the strain.”  Church's recent article describing the possible future benefits of his work, and possible future safety precautions."

Oh, think it’s time for bold amateur sci fi television?

Cool stuff on Stranger Things TV.
