Bold ideas for Planet Earth (Mostly science!)

Okay, I generally put aside most space and astronomy stuff for their own category. But I do have to say that while I am nototiously critical of the SLS/Artemis moondoggle, I do hope the three SLS monstrosities we've largely paid for will eventually work well, so we can get as much as 5% of our money's worth. And a useless-silly footprint stunt. Then - Heinlein-willing - commercial launch will consign the wretched thing to obsolescence and history and NASA can go back to the real business of grownups, way farther out. 


Oh, yes. The Large Hadron Collider is back up and upgraded, discovering tetra and even pent-quark particles. Some think there are now enough of these particles to begin grouping them together, like the chemical elements in the periodic table. That is an essential first step towards creating a theory and set of rules governing exotic mass.


== Saving Earth through geo-engineering? ==


One newly proposed method for addressing climate change involves sequestering plant waste CROPS: Crops Residue Oceanic Permanent Sequestration (competing for an X-Prize for carbon removal) envisions reducing atmospheric carbon dioxide by bundling agricultural waste into half-ton cubes and disposing of them in the deep ocean, below the thermocline - in extremely cold water, where their carbon will be undisturbed for millennia. This should be substantially less expensive than attempting to remove carbon dioxide by industrial processes. And the odds of it being politically acceptable are...


Other concepts being explored: The idea of using sun-shields to block maybe 1% of incoming sunlight – and perhaps even more of the UV – has a new proposed method… blowing giant bubbles. Intriguing and it may come to that. But still very expensive and it only works until something happens out there and it stops.


Gregory Benford and some others prefer that far-cheaper prospect of aerosols spread in the upper atmosphere that reflect light back into space. On paper and in the lab, they are short-lived and harmless. But again, any time you stop, all benefits are lost.


Much more effective across millions of years would be my method to enlarge (gradually) Earth’s orbit. Decidedly easy for some future civ to do… maybe even our g-g-g-kids, since it only requires 1000x the might of this already mighty civilization!  See my video Lift the Earth! as well as the numbers behind the idea.


But I have long favored another approach that appears to be a win-win, all around! From Phys.org“When smoke from the 2019–2020 Australian wildfires billowed across the Southern Ocean, the iron-rich particles it deposited on the ocean triggered an algae bloom bigger than Australia—and it had a rapid and prolonged impact on the Southern Ocean's marine ecosystem and its carbon cycle.” … 

“The phytoplankton bloom outlasted the wildfires by almost half a year. Phytoplankton blooms don't usually survive longer than a few weeks, so the duration of this bloom was astounding and has rarely been observed before on such time scales.”

Read the article. The hope is that ocean fertilization into strong currents (not contricted zones like the Black Sea, Med and Caribbean) can lead to plankton, then krill, then burgeoning of whale population back to pre-indistrial levels, which some believe could make the fertilization cycle persistent with their... well... whale... poop.

Which segués kinda naturally into our final geoengineering project and the most-necessady!

Peecycling! Not urinating while on a bike! No, it’s giving urine back to nature along (especially) with the rare phosphorus (P!) that otherwise gets flushed to sea. In 99% of humans, pee is perfectly harmless when cycled through dirt and foliage or flowers, and recycling it may even be required, someday, as I depict in the future, in Existence.


Again... P (Phosphorus) will be the next scarcity, far more than oil ever was. Time to be thinking about it, before the King of Morrocco owns the world. Do see Existence.


== Our bio future ==


Scientists in Sweden have created a liquid that can absorb solar energy and store it as a thermal fuel for as long as 18 years. The fluid works like a rechargeable battery, but instead of electricity, sunlight goes in and heat comes out when it's needed. It appears to be about Hydrogen plus Methane, but looking into it.  


Artificial photosynthesis can produce food without sunshine: A two-step electrocatalytic process can convert carbon dioxide, electricity, and water into acetate, the form of the main component of vinegar. Food-producing organisms then consume acetate in the dark to grow. ‘Combined with solar panels to generate the electricity to power the electrocatalysis, this hybrid organic-inorganic system could increase the conversion efficiency of sunlight into food, up to 18 times more efficient for some foods.’ Feed such a system CO2 directly from major producers like cement factories and the phase two reactors get nutrients from agricultural runoff. Very similar to current prototype systems using algae and sunlight.


Experiments showed that a wide range of food-producing organisms can be grown in the dark directly on the acetate-rich electrolyzer output, including green algae, yeast, and fungal mycelium that produce mushrooms. Producing algae with this technology is approximately fourfold more energy efficient than growing it photosynthetically. Yeast production is about 18-fold more energy efficient than how it is typically cultivated using sugar extracted from corn.” And "Using artificial photosynthesis approaches to produce food could be a paradigm shift for how we feed people.” 


== Interesting research ==


The rate of developing Alzheimer's was lowest among those who consistently received the flu vaccine every year, a very large study says. Though people who received at least one influenza vaccine were 40% less likely than their non-vaccinated peers to develop Alzheimer's disease over the course of four years.  "Since there is evidence that several vaccines may protect from Alzheimer's disease, we are thinking that it isn't a specific effect of the flu vaccine."


Like the new ‘miracle” cancer treatment etc., I am not betting the farm on preliminary results!  Still… track this…. Alas, it bodes poorly for Trumpist America.


New research turns the idea of heat-loving dinosaurs on its head: It presents the first physical evidence that Triassic dinosaur species, which were a minor group largely relegated to the polar regions at the time, regularly endured freezing conditions there. Hence when a sudden ice age swept the planet at the begin of the Jurassic, the cold tolerant and feathered dinosaurs swept in too.


Unusual superconductivity observed in twisted trilayer graphene: "While superconductors have been around for a long time, a remarkably new feature in twisted graphene bilayers and trilayers is that superconductivity in these materials can be turned on simply through the application of a voltage on a nearby electrode…"


And so we move onward. A spectacular scientific civilization! Whose fact-based professions are truly the groups who are vastly more-hated upon than all the races and genders. Wager me on that and let's compare actual amounts of time spent in direct dissing, on Fox. We're on the same side!


The side of a future with some hope.

The Robots and Foundation Universe: Issues Left For Us by Isaac Asimov


"It is the business of the future to be dangerous."
-- A.N. Whitehead 


A week ago, I explored the complex matter of Robert A. Heinlein. Now, let's dive deeply for a close look at another of our field's Grand Masters... one about whom I am officially an expert!

== Isaac Asimov and the joy of endless argument ==

Ah, robots.

Ever since Karel Capek coined the word in his stage play “R.U.R.”, its meaning has gone through steady transformation.  The fleshy slave-workers of Capek’s drama would today be called “androids” or be likened to the replicants of BLADE RUNNERRobots per se became associated with metal and plastic... computer chips and cool, artificial intelligence, without direct connection to protoplasm.  

Like aliens, robots have served as foils for two great drivers of sci fi plotting -- the Dangerous Other Who Must Be Feared... 

...and the Innocent Other Who Must Be Protected From Vile Humanity... especially our wretched and oppressive institutions.  

We all remember many examples of both kinds.  From viciously genocidal machines of THE TERMINATOR and THE MATRIX to cute little robots who are pursued by nasty generals, in SHORT CIRCUIT and D.A.R.Y.L.

Some science fiction tales did try to move beyond these awful cliches. I am reminded of Robert Heinlein’s THE DOOR INTO SUMMER, whose hero is a tinkerer-inventor, building household automatons that are actually useful in the home, without necessarily writing sonnets or planning extinction for all humankind. (The inspiration for today's successful iRobot corporation.) Indeed, this gradual introduction of utilitarian models better predicted events than any of the clanking humanoids that spun off the pages and screens of bad sci fi over the decades.

But no article on this topic would get far without turning our attention to the biggest and most impressive science fictional universe in which robots hold a major presence -- the “Robots and Foundation” universe that was created, over the course of a lifetime, by one of SF’s Grand Masters... the good doctor Isaac Asimov.

I had the honor of being chosen to “clean up”.... to tie the loose ends that Isaac left dangling when he so lamentably left us too early, some years ago.  Along with my collaborators and pals, Gregory Benford and Greg Bear, I helped create the new SECOND FOUNDATION TRILOGY, with the blessing of Isaac’s heirs, his wife Janet and daughter Robin.  These books can be read separately or (loosely) together.

 As author of the final book, I had a mission a bit different than Greg and Gregory, whose fine novels zeroed in on certain details of the life of Hari Seldon.  Never shy, I went the other direction, attempting to bring together all of Isaac’s themes -- even from obscure titles like PEBBLE IN THE SKY -- in a final grand adventure, entitled FOUNDATION’S TRIUMPH. Believe me, that required a lot of study!  And revisiting great old tales in one of the finest epics of all time.

Hence, in honor of what would have been Isaac's birthday, this week, I’ll let you in on some of the background story...

== The explorer begins in New York ==

Isaac Asimov first started pondering human destiny while working in his father's candy store, at a time when the world was in turmoil. Vast, inscrutable forces appeared to be working on humanity, making whole populations behave in unfathomably dangerous ways - often against their own self interest. Countless millions believed that the answer lay in prescriptions - in formulas for human existence - called ideologies.

Young Isaac was too smart to fall for any of the dogmas then on sale. From Marxism to fascism to ultra-capitalism, they all preached that human beings are simple creatures, easily described and predictable according to incantations scribbled on a few printed pages. 

Even as a youth, then as a student, Isaac could tell that these scenarios were wishful-thinking, having more in common with religion than real science. Yet, he could easily understand why people yearned for a model - a paradigm - for human behavior. Surrounded by irrationality on all sides, Isaac dreamed that maybe, someday, someone might discover how to deal with the quirky complexity of contradictory human nature... if not individuals, then perhaps the great mass of humanity.

He had no idea how to solve such a problem, and was too sensible to expect useful formulae from the fools and demagogues ranting on mid-Twentieth Century radio. But what about the far future? How about when human beings filled the galaxy? Might so many individual foibles cancel out, simplifying the problem enough to let mathematics describe human momentum, the way chemistry’s gas laws simplify the behavior of vast numbers of molecules?

Take this notion and combine it with young Isaac's reading matter; one summer he devoured Gibbon's DECLINE AND FALL OF THE ROMAN EMPIRE. Now stir in a poetic soul and a little yearning for adventure... can you start to see a pattern developing? One that would eventually turn into one of the great classics of mid-20th Century science fiction.

== The archetype nerdish power! ==

It all starts with Hari Seldon, a character that most critics closely identify with Asimov, the writer-scientist himself. Seldon only appears as an active character at the very beginning of the original FOUNDATION TRILOGY. But his shadow stretches onward, across all of the many short stories and novels that span five hundred years of history and many thousands of starry parsecs.

In later novels we learn of meddling by another trademarked Asimov character, the mighty immortal robot, Daneel Olivaw. But at first, here in Asimov’s first great work - the Trilogy - the tale appears to be limited to human beings. Ten quadrillion humans... and an idea. One of the biggest ideas.

The idea that we - or maybe just a few of us - might look ahead, spot the inevitable mistakes and jagged reefs, somehow charting a course around the most dangerous shoals, leading eventually to a better shore.

What a concept to explore! But Isaac Asimov’s fertile mind did not stop there. Another matter roiling in his brain was the problem of Robots. Far too long maligned as Frankenstein monsters, in magazines with lurid covers, they seemed to him filled with far greater possibilities. Yes, the simple-minded approach was to make them objects of dread. But what if we could program them to stay loyal? To grow with us? And maybe to grow better than us... while remaining faithful to the last?

The result - Asimov's universe of Robot Stories - became another instant classic of science fiction, introducing several concepts, such as deeply-programmed protective "laws" that are widely discussed by Artificial Intelligence researchers today

The Foundation Universe and the Robots - for many years, these two cycles of fiction stayed separate. 

Then Asimov did something controversial. He chose to combine them. It seemed a strange decision at the time. Indeed, as a teenager in the 1960s and 1970s I was -- shall we say -- a bit cheesed at the Good Doctor, for what I then deemed to be a terrible self-indulgence! So, we have robots int he 20th and 21st Centuries... but non in the year 3030?  Say what?

But in the long run, that combination brought about something truly remarkable. A great conversation. A conversation between Asimov and his readers. 

And one that Isaac kept thrashing back and forth... with himself.

== Isaac's journey ==

Indeed, Isaac Asimov kept re-adjusting focus in his universe!  Like any truly honest scientist, he re-evaluated. Each and every decade, Isaac found hidden implications in his universe.  Things that were already tacit, between the lines. In meticulous honesty, he always bared these implications and explored them... till the next decade started another round.

Follow along closely, and be amazed.

First he wrought the Foundation, treating a quadrillion humans as ‘gas molecules’ whose destiny could be calculated through Hari Seldon’s wondrous new science of psychohistory. And that satisfied the young nerd in biochemistry... for a while. Only...

Later, Isaac realized that perturbations would interfere with statistical predictability, even in such a marvelous new science. (Today we call it the Butterfly Effect.)

So he introduced a secret cabal of psychic-mathematicians (the Second Foundation) who would be dedicated to guiding the Seldon Plan back in line, should the emerging New Empire drift down a wrong path.

That seemed to satisfy, for a while. 

But a decade or so afterwards, Isaac realized the moral flaw of the Second Foundation... that it left humanity led forever by a secret, inherited aristocracy!  A mutant branch of the race, locked into permanent, psychic dominance over all the rest.

This was offensive to Isaac’s liberal-democratic sensibilities. Hence, he searched and found a solution to this, by bringing both halves of his life-work together... by inserting robots into the Foundation Universe!

Daneel Olivaw and his scrupulously honest positronic followers would act behind the scenes, manipulating even the Second Foundation, all for our own best interests and welfare, of course, and preventing dominance by a lordly human caste. Picture dedicated court eunuchs, who cannot conspire to become lords themselves, because they will have no offspring. (And hence my observation that Asimov's fabled Empire was less Roman than actually rather Chinese!)

Loyal robot eunuchs, standing beind the Second Foundation, manipulating it to only do good. They can be trusted... right?

Or can they? A little while later, Isaac realized something... free will had been reversed!  

The mechanical servants had memory and volition. They were rare, precious and powerful! While humans were as numerous and powerless as insects. The "masters" had amnesia about their past and no control over their future, utterly and secretly controlled by all-powerful "servants." Now that didn’t sound like such a great destiny either! 

What a life Isaac had! Holding this decadal conversation and argument with himself. Finding an answer to a problem, then having the honesty to admit that it caused a new problem! And answering that one... only then honestly coming to realize...

== Iterating Destiny ==

He sought a way out of the powerful-servants dilemma of the 1980s... and came up with Gaia! The ultimate robotic plan for humanity -- for us to transcend together as a race, leapfrogging beyond our loyal-but-manipulative servants into a a new level of being, transforming all of humanity into a single, all-powerful mind! 

Okay, you've seen this concept positively portrayed by a third of the greats... by Arthur C. Clarke* in CHILDHOOD’S END and in 2001: A Space Odyssey... and it goes back to Teilhard de Chardin and others. But never explored with Asimovian attention to detail. You've also seen this notion -- of monolithic group transcendence -- portrayed negatively in Star Trek’s infamous Borg! (Indeed, I tried to give it a subtle twist-and-spin in EARTH.) 

The Gaia/Galaxia resolution that Isaac put forward in FOUNDATION’S EDGE seemed to solve his problems. It would eventually deify humanity, restoring our memory and authority over robots again, in a fashion that Daneel Olivaw would find acceptable, because it would eliminate the fractious individualism that was always messing things up with violence and confusion and chaos. Such a coalescence into mega wisdom would make humanity mature, allowing Daneel at last to put down his ancient burden and step aside for a long deserved rest.

Only then Isaac took things to the next level, and realized... hey, wait a minute!  Maybe this "solution" needs some tweaking, as well.

== We'll never know for sure. ==

Asimov added several entire courses to our endless and ongoing dinner-table conversation about destiny. Alas though, his time was up. A sad flaw in the 1980s blood banks robbed us of his brilliance. 

Still... curious minds demand more! Where would he have gone next! His shoes were hard to fill, but someone had to try. 

In fact, Isaac dropped plenty of hints, before he died. In scores of details, and in the momentum of ideas, he actually made it pretty clear... at least to Benford and Bear and me... where the next dilemma lay.

In continuing Isaac Asimov's epochal saga, Gregory Benford, Greg Bear and I faced a daunting challenge - to keep adding ideas and possibilities to the Foundation/Robots setting. Concepts that captivate the reader. Visions that are new, awesome and wonderful, illuminated in stories filled with interesting characters and vivid adventure. And yet, we had to remain true to Isaac's overall vision of a startling and intellectually stimulating future.

Fortunately, Isaac's clues -- like those in a good detective story -- were all there, if you looked closely! Pointing to mysteries and logical quandaries that he clearly meant to deal with someday. 

We also had to capture the delightful flavor of an Asimovian tale!  Isaac was, above all, a lover of detective stories, and so, logical twists and turns carried over into his science fiction. Furthermore, readers of his works have come to expect certain traditions.

The protagonist faces adversaries whose masked motives are peeled away through logic and insight, with successive reversals offering delicious surprise.


Tantalizing mysteries. Isaac left "hanging questions" in many books... using these as hooks for the next tale. New books should continue this tradition of asking more unanswered questions.

Moral quandaries. Isaac wasn't afraid of presenting readers with ethically ambivalent situations. The hero must choose among several paths, each with advantages and drawbacks. Villains have reasons for their actions.

Issues of cosmic relevance. Isaac dealt with DESTINY.

Frequent referral to events in other books. While each of his tales can be immensely satisfying on his own, Isaac's readers also loved catching brief references to events that took place elsewhere in his universe.

These traditions combined into a classic futuristic universe, a stage where we could watch a play as vivid and timeless as anything by Hugo or Dumas.

== And returning to... ==

Finally, there is Hari Seldon (who is also the hero of our new Second Foundation Trilogy), a monumental figure, able to see so much about human destiny, yet also feeling himself trapped by strange forces that he barely understands... until achieving a strange triumph at the very end. His struggles to bring humanity -- at long last -- to a sanctuary of happiness and fulfillment are epochal

Mortality catches up with us all. But the logic is right there - a path implied by several dozen delicious clues that Isaac laid down, over the years. Clearly, he was not finished amazing us. These clues told a new generation of writers what to do next.

What matters is to stay enthralled, remaining ready to be provoked by new thoughts, to keep pushing back the curtain a little bit, learning and discussing more about our future.  Whether the topic is robots... how to keep them loyal and interesting... 

...or almost any other dramatic device of science fiction... dramatic devices that may become tomorrow’s world-wreckers... or household convenience.

The adventure continues. Enjoy! And keep thinking about our wide-open destiny.

(Addendum #1: A reader's guide to the Second Foundation Trilogy.
All three of our books in the 2nd trilogy can be read separately or in any order. Bear's and Benford's each show a vigorous, younger Hari Seldon, while in Foundation's Triumph, I tackle Hari's series of realizations and fateful decisions, at the very end of his life, including a final and fateful confrontation with R. Daneel Olivaw. 

(In Foundation's Fear, Benford takes you on a rapid-fire adventure with many non-canonical twists. In Foundation and Chaos, Greg Bear provides a strong Asimovian Voice in Isaac's favorite detective format... while I aimed for sweep, tying together many loose ends and shining light on a surprise culmination that -- I believe -- will make you say: "That HAS to be where Isaac was going!" Here's hoping you feel stimulated to think many new thoughts. That is - after all - what that puckish brain-stirrer, Isaac Asimov, loved most to do.)

(Addendum #2: Here's a handy guide to the chronology of Isaac Asimov’s brilliant Foundation and Robots universe. 
         The chronology helps, if you want to read them in order as a “history.” 
         If, on the other hand, you want to get to the "meat" of the main ideas, gathering the overview of grand concepts (but skipping some great yarns)... I recommend this order: 10, 11, 12, 2, 5, 13, 9d. More below, in comments! And your own opinions are welcome.)
