The Future of Computing: Towards a Quantum Internet

quantun_internetFor decades, the dream of quantum computing – a system that makes direct use of quantum-mechanical phenomena, such as superposition and entanglement, to perform operations on data- has been just that. Much the same is true of principles that expand on this concept, such as quantum encryption and a quantum internet. But thanks to ongoing studies and experiments by researchers and scientists, that dream may be closer to fruition than ever.

This time the progress comes from a research team out of Professor Nicolas Gisin lab’s in the physics department at the University of Geneva. The team achieved the teleportation of the quantum state of a photon – this time, the photon’s polarization – to a crystal-encased photon more than 25 kilometers (15.5 miles) away. The distance breaks the previous record of 6 kilometers (3.7 miles) set 10 years ago by the same team using the same method.

quantum_crystalThis is the latest in a series of experiments the group, led by physicist Félix Bussières, have conducted over the last decade in an effort to better understand quantum data transfer. In this particular experiment, the researchers stored one photon in a crystal, essentially creating a solid-state memory bank. They sent another photon of a different wavelength 25 km away through optical fiber, whereupon they had it interact with a third photon.

Because the first two photons were entangled – a quantum property whereby particles can speak to each other across an infinite distance – the interaction sent the data to the photo stored in the memory bank, where the team was able to retrieve it. Or as the team explained, using pool balls as an anology:

It is a bit like a game of billiards, with a third photon hitting the first which obliterates both of them. Scientists measure this collision. But the information contained in the third photon is not destroyed – on the contrary it finds its way to the crystal which also contains the second entangled photon.

quantum-entanglement3This is all in keeping with the concept of quantum teleportation – the moving of quantum data from one location to another without having to travel the distance between them. That means that the speed at which data moves isn’t necessarily limited by the constraints of space and time. In that sense, it’s easier to think of this kind of teleporting not as a “beam me up” scenario, but as a kind of instantaneous awareness between two points.

While this may not sound as exciting as Ursula K. Le Guin’s Ansible communicator, the Alcubierre warp drive, or the “Star Trek”-style transporter, it opens up startling possibilities. For instance, in addition to bringing us closer to hard drives that can store quantum bits (aka. qubits), this is a major step in the direction of a quantum internet and encryption- where information is sent around the world instantaneously and is extremely secure.

quantum-teleportation-star-trails-canary-islands-1-640x353This also opens doors for space exploration, where astronauts in space, rovers on Mars, and satellites in deep space will be able to communicate instantly with facilities here on Earth. For non-quantum physicists, the novel aspect of this experiment is that the team achieved teleportation of data across the kind of optic fiber that forms the basis of modern-day telecommunications, which means no major overhaul will be needed to make quantum internet a reality.

As physicists continue to push the boundaries of our understanding about the quantum world, we’re getting closer to translating these kinds of advancements in market applications. Already, quantum computing and quantum encryption are making inroads into the sectors of banking security, medical research and other areas in need of huge computing muscle and super-fast information transfer.

^With the rise of a potential quantum Internet on the horizon, we could see the next jump in communication happen over the next couple of decades. So while we’re a long way off from trying to pry quantum teleportation and entanglement from the grip of the theoretical realm, scientists are making headway, if only a handful of kilometers at a time. But every bit helps, seeing as how routing stations and satellites can connect these distances into a worldwide network.

In fact, research conducted by other labs have not only confirmed that quantum teleportation can reach up to 143 km (89 miles) in distance, but that greater and greater properties can be beamed. This distance is especially crucial since it happens to be close to what lies between the Earth and a satellite in Low-Earth Orbit (LEO). In short, we humans could construct a quantum internet using optic cables or satellites, mirroring the state of telecommunications today.

And when that happens, get ready for an explosion in learning, processing and information, the likes of which has not been seen since the creation of the printing press or the first internet revolution!

The Future of Space Exploration

spacex-icarus-670Back in January, National Geographic Magazine celebrated its 125th anniversary. In honor of this occasion, they released a special issue which commemorated the past 125 years of human exploration and looked ahead at what the future might hold. As I sat in the doctor’s office, waiting on a prescription for antibiotics to combat my awful cold, I found myself terribly inspired by the article.

So naturally, once I got home, I looked up the article and its source material and got to work. The issue of exploration, especially the future thereof, is not something I can ever pass up! So for the next few minutes (or hours, depending on how much you like to nurse a read), I present you with some possible scenarios about the coming age of deep space exploration.

MarsOneSuffice it to say, National Geographic’s appraisal of the future of space travel was informative and hit on all the right subjects for me. When one considers the sheer distances involved, not to mention the amount of time, energy, and resources it would take to allow people to get there, the question of reaching into the next great frontier poses a great deal of questions and challenges.

Already, NASA, Earth’s various space agencies and even private companies have several ideas in the works or returning to the Moon, going to Mars, and to the Asteroid Belt. These include the SLS (Space Launch System), the re-purposed and upgraded version of the Saturn V rocket which took the Apollo astronauts to the Moon. Years from now, it may even be taking crews to Mars, which is slated for 2030.

ESA_moonbaseAnd when it comes to settling the Moon, Mars, and turning the Asteroid Belt into our primary source of mineral extraction and manufacturing, these same agencies, and a number of private corporations are all invested in getting it done. SpaceX is busy testing its reusable-launch rocket, known as the Grasshopper, in the hopes of making space flight more affordable. And NASA and the ESA are perfecting a process known as “sintering” to turn Moon regolith into bases and asteroids into manufactured goods.

Meanwhile, Virgin Galactic, Reaction Engines and Golden Spike are planning to make commercial trips into space and to the Moon possible within a few years time. And with companies like Deep Space Industries and Google-backed Planetary Resources prospeting asteroids and planning expeditions, it’s only a matter of time before everything from Earth to the Jovian is being explored and claimed for our human use.

But when it comes to deep-space exploration, the stuff that would take us to the outer reaches of the Solar System and beyond, that’s where things get tricky and pretty speculative. Ideas have been on the table for some time, since the last great Space Race forced scientists to consider the long-term and come up with proposed ways of closing the gap between Earth and the stars. But to this day, they remain a scholarly footnote, conceptual and not yet realizable.

But as we embark of a renewed era of space exploration, where the stuff of science fiction is quickly becoming the stuff of science fact, these old ideas are being dusted off, paired up with newer concepts, and seriously considered. While they might not be feasible at the moment, who know what tomorrow holds? From the issues of propulsion, to housing, to cost and time expenditures, the human race is once again taking a serious look at extra-Solar exploration.

And here are some of the top contenders for the “Final Frontier”:

Nuclear Propulsion:
Project-Orion-Spacecraft
The concept of using nuclear bombs (no joke) to propel a spacecraft was first proposed in 1946 by Stanislaw Ulam, a Polish-American mathematician who participated in the Manhattan Project. Preliminary calculations were then made by F. Reines and Ulam in 1947, and the actual project – known as Project Orion was initiated in 1958 and led by Ted Taylor at General Atomics and physicist Freeman Dyson from the Institute for Advanced Study in Princeton.

In short, the Orion design involves a large spacecraft with a high supply of thermonuclear warheads achieving propulsion by releasing a bomb behind it and then riding the detonation wave with the help of a rear-mounted pad called a “pusher”. After each blast, the explosive force is absorbed by this pusher pad, which then translates the thrust into forward momentum.

Though hardly elegant by modern standards, the proposed design offered a way of delivering the explosive (literally!) force necessary to propel a rocket over extreme distances, and solved the issue of how to utilize that force without containing it within the rocket itself. However, the drawbacks of this design are numerous and noticeable.

Orion SchematicF0r starters, the ship itself is rather staggering in size, weighing in anywhere from 2000 to 8,000,000 tonnes, and the propulsion design releases a dangerous amount of radiation, and not just for the crew! If we are to rely on ships that utilize nuclear bombs to achieve thrust, we better find a course that will take them away from any inhabited or habitable areas. What’s more, the cost of producing a behemoth of this size (even the modest 2000 tonne version) is also staggering.

Antimatter Engine:
NASA_antimatterMost science fiction authors who write about deep space exploration (at least those who want to be taken seriously) rely on anti-matter to power ships in their stories. This is no accident, since antimatter is the most potent fuel known to humanity right now. While tons of chemical fuel would be needed to propel a human mission to Mars, just tens of milligrams of antimatter, if properly harnessed, would be able to supply the requisite energy.

Fission and fusion reactions convert just a fraction of 1 percent of their mass into energy. But by combine matter with antimatter, its mirror twin, a reaction of 100 percent efficiency is achieved. For years, physicists at the CERN Laboratory in Geneva have been creating tiny quantities of antimatter by smashing subatomic particles together at near-light speeds. Given time and considerable investment, it is entirely possible this could be turned into a form of advanced propulsion.

In an antimatter rocket, a dose of antihydrogen would be mixed with an equal amount of hydrogen in a combustion chamber. The mutual annihilation of a half pound of each, for instance, would unleash more energy than a 10-megaton hydrogen bomb, along with a shower of subatomic particles called pions and muons. These particles, confined within a magnetic nozzle similar to the type necessary for a fission rocket, would fly out the back at one-third the speed of light.

antimatter_shipHowever, there are natural drawback to this design as well. While a top speed of 33% the speed of light per rocket is very impressive, there’s the question of how much fuel will be needed. For example, while it would be nice to be able to reach Alpha Centauri – a mere 4.5 light years away – in 13.5 years instead of the 130 it would take using a nuclear rocket, the amount of antimatter needed would be immense.

No means exist to produce antimatter in such quantities right now, and the cost of building the kind of rocket required would be equally immense. Considerable refinements would therefore be needed and a sharp drop in the cost associated with building such a vessel before any of its kind could be deployed.

Laser Sail:
solar_sail1Thinking beyond rockets and engines, there are some concepts which would allow a spaceship to go into deep space without the need for fuel at all. In 1948, Robert Forward put forward a twist on the ancient technique of sailing, capturing wind in a fabric sail, to propose a new form of space travel. Much like how our world is permeated by wind currents, space is filled with cosmic radiation – largely in the form of photons and energy associated with stars – that push a cosmic sail in the same way.

This was followed up again in the 1970’s, when Forward again proposed his beam-powered propulsion schemes using either lasers or masers (micro-wave lasers) to push giant sails to a significant fraction of the speed of light. When photons in the laser beam strike the sail, they would transfer their momentum and push the sail onward. The spaceship would then steadily builds up speed while the laser that propels it stays put in our solar system.

Much the same process would be used to slow the sail down as it neared its destination. This would be done by having the outer portion of the sail detach, which would then refocus and reflect the lasers back onto a smaller, inner sail. This would provide braking thrust to slow the ship down as it reached the target star system, eventually bringing it to a slow enough speed that it could achieve orbit around one of its planets.

solar_sailOnce more, there are challenges, foremost of which is cost. While the solar sail itself, which could be built around a central, crew-carrying vessel, would be fuel free, there’s the little matter of the lasers needed to propel it. Not only would these need to operate for years continuously at gigawatt strength, the cost of building such a monster would be astronomical, no pun intended!

A solution proposed by Forward was to use a series of enormous solar panel arrays on or near the planet Mercury. However, this just replaced one financial burden with another, as the mirror or fresnel lens would have to be planet-sized in scope in order for the Sun to keep the lasers focused on the sail. What’s more, this would require that a giant braking sail would have to be mounted on the ship as well, and it would have to very precisely focus the deceleration beam.

So while solar sails do present a highly feasible means of sending people to Mars or the Inner Solar System, it is not the best concept for interstellar space travel. While it accomplishes certain cost-saving measures with its ability to reach high speeds without fuel, these are more than recouped thanks to the power demands and apparatus needed to be it moving.

Generation/Cryo-Ship:
ringworld2Here we have a concept which has been explored extensively in fiction. Known as an Interstellar Ark, an O’Neill Cylinder, a Bernal Sphere, or a Stanford Taurus, the basic philosophy is to create a ship that would be self-contained world, which would travel the cosmos at a slow pace and keep the crew housed, fed, or sustained until they finally reached their destination. And one of the main reasons that this concept appears so much in science fiction literature is that many of the writers who made use of it were themselves scientists.

The first known written examples include Robert H. Goddard “The Last Migration” in 1918, where he describes an “interstellar ark” containing cryogenic ally frozen people that set out for another star system after the sun died. Konstantin E. Tsiolkovsky later wrote of “Noah’s Ark” in his essay “The Future of Earth and Mankind” in 1928. Here, the crews were kept in wakeful conditions until they reached their destination thousands of years later.

enzmann_starshipBy the latter half of the 20th century, with authors like Robert A. Heinlein’s Orphans of the Sky, Arthur C. Clarke’s Rendezvous with Rama and Ursula K. Le Guin’s Paradises Lost, the concept began to be explored as a distant possibility for interstellar space travel. And in 1964, Dr. Robert Enzmann proposed a concept for an interstellar spacecraft known as the Enzmann Starship that included detailed notes on how it would be constructed.

Enzmann’s concept would be powered by deuterium engines similar to what was called for with the Orion Spacecraft, the ship would measure some 600 meters (2000 feet) long and would support an initial crew of 200 people with room for expansion. An entirely serious proposal, with a detailed assessment of how it would be constructed, the Enzmann concept began appearing in a number of science fiction and fact magazines by the 1970’s.

RAMA2Despite the fact that this sort of ship frees its makers from the burden of coming up with a sufficiently fast or fuel-efficient engine design, it comes with its own share of problems. First and foremost, there’s the cost of building such a behemoth. Slow-boat or no, the financial and resource burden of building a mobile space ship is beyond most countries annual GDP. Only through sheer desperation and global cooperation could anyone conceive of building such a thing.

Second, there’s the issue of the crew’s needs, which would require self-sustaining systems to ensure food, water, energy, and sanitation over a very long haul. This would almost certainly require that the crew remain aware of all its technical needs and continue to maintain it, generation after generation. And given that the people aboard the ship would be stuck in a comparatively confined space for so long, there’s the extreme likelihood of breakdown and degenerating conditions aboard.

Third, there’s the fact that the radiation environment of deep space is very different from that on the Earth’s surface or in low earth orbit. The presence of high-energy cosmic rays would pose all kinds of health risks to a crew traveling through deep space, so the effects and preventative measures would be difficult to anticipate. And last, there’s the possibility that while the slow boat is taking centuries to get through space, another, better means of space travel will be invented.

Faster-Than-Light (FTL) Travel:
???????????????????????Last, we have the most popular concept to come out of science fiction, but which has received very little support from scientific community. Whether it was the warp drive, the hyperdrive, the jump drive, or the subspace drive, science fiction has sought to exploit the holes in our knowledge of the universe and its physical laws in order to speculate that one day, it might be possible to bridge the vast distances between star systems.

However, there are numerous science based challenges to this notion that make an FTL enthusiast want to give up before they even get started. For one, there’s Einstein’s Theory of General Relativity, which establishes the speed of light (c) as the uppermost speed at which anything can travel. For subatomic particles like photons, which have no mass and do not experience time, the speed of light is a given. But for stable matter, which has mass and is effected by time, the speed of light is a physical impossibility.

Galactica_newFor one, the amount of energy needed to accelerate an object to such speeds is unfathomable, and the effects of time dilation – time slowing down as the speed of light approaches – would be unforeseeable. What’s more, achieving the speed of light would most likely result in our stable matter (i.e. our ships and bodies) to fly apart and become pure energy. In essence, we’d die!

Naturally, there have been those who have tried to use the basis of Special Relativity, which allows for the existence of wormholes, to postulate that it would be possible to instantaneously move from one point in the universe to another. These theories for “folding space”, or “jumping” through space time, suffer from the same problem. Not only are they purely speculative, but they raise all kinds of questions about temporal mechanics and causality. If these wormholes are portals, why just portals in space and not time?

The supermassive black hole at the center of the Milky Way galaxy.And then there’s the concept of a quantum singularity, which is often featured in talk of FTL. The belief here is that an artificial singularity could be generated, thus opening a corridor in space-time which could then be traversed. The main problem here is that such an idea is likely suicide. A quantum singularity, aka. a black hole, is a point in space where the laws of nature break down and become indistinguishable from each other – hence the term singularity.

Also, they are created by a gravitational force so strong that it tears a hole in space time, and that resulting hole absorbs all things, including light itself, into its maw. It is therefore impossible to know what resides on the other side of one, and astronomers routinely observe black holes (most notably Sagittarius A at the center of our galaxy) swallow entire planets and belch out X-rays, evidence of their destruction. How anyone could think these were a means of safe space travel is beyond me! But then again, they are a plot device, not a serious idea…

alcubierre-warp-drive-overviewBut before you go thinking that I’m dismissing FTL in it’s entirety, there is one possibility which has the scientific community buzzing and even looking into it. It’s known as the Alcubierre Drive, a concept which was proposed by physicist Miguel Alcubierre in his 1994 paper: “The Warp Drive: Hyper-Fast Travel Within General Relativity.”

The equations and theory behind his concept postulate that since space-time can be contracted and expanded, empty space behind a starship could be made to expand rapidly, pushing the craft in a forward direction. Passengers would perceive it as movement despite the complete lack of acceleration, and vast distances (i.e. light years) could be passed in a matter of days and weeks instead of decades. What’s more, this “warp drive” would allow for FTL while at the same time remaining consistent with Einstein’s theory of Relativity.

In October 2011, physicist Harold White attempted to rework the equations while in Florida where he was helping to kick off NASA and DARPA’s joint 100 Year Starship project. While putting together his presentation on warp, he began toying with Alcubierre’s field equations and came to the conclusion that something truly workable was there. In October of 2012, he announced that he and his NASA team would be working towards its realization.

But while White himself claims its feasible, and has the support of NASA behind him, the mechanics behind it all are still theoretical, and White himself admits that the energy required to pull off this kind of “warping” of space time is beyond our means at the current time. Clearly, more time and development are needed before anything of this nature can be realized. Fingers crossed, the field equations hold, because that will mean it is at least theoretically possible!

warp_drive

Summary:
In case it hasn’t been made manifestly obvious by now, there’s no simple solution. In fact, just about all possibilities currently under scrutiny suffer from the exact same problem: the means just don’t exist yet to make them happen. But even if we can’t reach for the stars, that shouldn’t deter us from reaching for objects that are significantly closer to our reach. In the many decades it will take us to reach the Moon, Mars, the Asteroid Belt, and Jupiter’s Moons, we are likely to revisit this problem many times over.

And I’m sure that in course of creating off-world colonies, reducing the burden on planet Earth, developing solar power and other alternative fuels, and basically working towards this thing known as the Technological Singularity, we’re likely to find that we are capable of far more than we ever thought before. After all, what is money, resources, or energy requirements when you can harness quantum energy, mine asteroids, and turn AIs and augmented minds onto the problems of solving field equations?

Yeah, take it from me, the odds are pretty much even that we will be making it to the stars in the not-too-distant future, one way or another. As far as probabilities go, there’s virtually no chance that we will be confined to this rock forever. Either we will branch out to colonize new planets and new star systems, or go extinct before we ever get the chance. I for one find that encouraging… and deeply disturbing!

Top 15 Things You’ll Never Hear a Geek Say

white-and-nerdyThis really doesn’t happen, but it seems I gave myself an idea with that last post. And to think it all came of an inappropriate joke! Essentially, I began to joke about the kinds of things geeks never say and even listed a few. And it got me thinking, one thing this blog has been missing up until now is a top ten list of things you’ll never hear a geek say. Well, I tried to limit myself to ten, but it was impossible. And so I expanded it a little to incorporate just a few more. I know, top 15 lists aren’t as impressive, but what can you do? Sometimes, you just gotta be inclusive!

Oh, and word of warning, if you’re not a fan of inappropriate jokes, back yourselves up now because you don’t want to see some of the things I’ve written here. As a self-professed geek, I can say these things, but rest assured, my test audience (my wife) didn’t exactly react well 😉 You’ve been warned! Anyhoo, here they are, the top 15 things geeks never say, in ascending order:

15. “Jane Austin is a far superior writer to Ursula K. Le Guin”

14. “I would have liked to have seen less cleavage and more character development from 7 of 9” (substitute any female lead from Star Trek)

13. “The blue chick from Avatar was so not hot”

12. “George R.R. Martin didn’t hit his stride until the third book”

11. “There’s no way I’m paying 50 bucks for a video game!”

10. “I can see no difference between Captain Kirk and Picard”

9. “Blade Runner totally needs to be remade”

8. “I have no strong opinions either way on the remake”

7. “They made a show called The Big Bang Theory?”

6. “I didn’t see the new Star Trek movie, but I hear it’s good.”

5. “Frank Herbert would be so proud of what’s become of the Dune franchise”

4. “You’ll never catch me jerking off to anime!”

3. “The prequels are just as good as the original”

2. “The movie was just as good as the book”

1. “George Lucas didn’t rape my childhood!”

And I’m still thinking of some doozies! Oh well, maybe this can become a thing, but only top 10 lists from now on. 15 at a time is not a pace I foresee being able to keep up for long. Until next time, geek out, get your geek on, and keep on geeking in the free world! Have I found enough ways to work that into a cliched saying?

Utopian Science Fiction

Imminent Utopia by Kuksi

Welcome back my friends! A funny thing happened just this morning. I was looking at an old article –  titled Dystopian Science Fiction – and realized that something was missing. Yes, this is the article that earned me most of my current followers and the bulk of my traffic on this site, but I quickly came to the conclusion that there was a hidden voice in that little study that never got a chance to have its say.

Basically, when I was looking into dystopian literature, I realized that it and utopian literature are almost the same thing. You might say that they represent two sides of the same coin, not so much opposites as interchangeable facets where one can become the other with a simple turn of the wheel. So I asked myself, why then haven’t I compiled a list of the most popular Utopian literature to go along with my dystopian one? Having read Thomas More’s seminal book that started it all, I’m nothing if not incredibly fascinating by the subject. And anyone who knows me knows that I’m a nerd for research and can’t resist sharing what I find.

So why the hell haven’t I done this yet?! Don’t know, probably got swept away with all those posts about robots, ships, and guns. In any case, it’s a mistake I rectify here and now. Using the same format as my article on dystopian sci-fi, I’ve come up with a tentative list of the greatest forerunners, classics, and modern examples of utopia in literature. The list is by no means complete, but I feel it is a faithful sampling. You be the judge, here goes:

Earliest Examples:
The first acknowledged examples of utopian literature come to us from classical antiquity, when scholars reached beyond the old strictures of writing about dynastic struggle, great wars and the foundations of their empires to tackle issues such as justice, morality, and the driving forces of history. By asking these questions, and offering up possible explanations, they were to have an immeasurable effect on subsequent generations of intellectuals, statesmen and social reformers.

The Republic:
Written around 380 BCE by Plato, this is perhaps the oldest example of utopian literature. Written as an account of one of Socrates many dialogues, the chief purpose of this book was in finding the true definition of justice and what it takes to achieve a just city-state and a just man. As Plato’s best known work, it is also one of the most influential philosophical and intellectual texts in the history of western society and maybe even the world.

Made up of ten books, the account follows Socrates and his Athenian and foreign guests as they discuss various topics. Amongst them are whether or not the “just man” is happier than the “unjust man”, the theory of forms and universality, the nature of the soul, the role of the philosopher in society, and finally, what the different types of government are and what makes them just/unjust.

From Plato’s account, Socrates and his peers proposed that philosophers are the ideal statesmen and that justice can best be summed up by considering the common good rather than common sense definitions having to do with personal justice. In addition, the allegory of the cave – how we are all essentially prisoners and merely going by projections of truth rather than truth itself – was advanced. And finally, they listed the four predominant forms of government (timocracy, oligarchy, democracy and tyranny) and how they tended to devolve into each other.

Ultimately, the value of this work was in how it showed the connection between political cause and effect, and how it sought to create guidelines for good governance. It’s identification of the four major types of government has been used over and over in the history of political discourse and even became the basis of modern political sciences. And because of its focus on things like the common good and the idea of philosopher statesmen, it was also to have a profound influence on later generations of scholars, particularly Sir Thomas More, Thomas Hobbes and Karl Marx.

The City of God:
Written by St. Augustine of Hippo in the early 5th century CE, The City of God is considered one of the most important texts in the history of Christianity. Written after the Visigoth sack of Rome, the text was intended as much as a consolation to Christians as it was a discourse on theological matters. Basically, Augustine claimed that though the city of Rome had fallen, the City of God, the “eternal Jerusalem” still stood strong and would endure.

Essentially, Augustine advanced a perception of history in this book that was characterized by a dialectical process, or a conflict between opposites. On the one hand, there was the City of Man, characterized by earthly pleasures and decadence, and the City of God, dedicated to eternal truth. The conflict, he claimed, would end with victory for the latter, where people would throw off the bonds of an earthly paradise in favor of a spiritual one.

Thought it did not concern itself with matters of practical governance or how an ideal state could be created in the here and now, Augustine’s treatise was to have a profound effect on the fields of theology and philosophy. Basically, his idea of a city where spiritual purity could be attained became the basis for a theocratic state, while his theory on the dialectical process of history would go on to inspire men like W.F. Hegel and (again) Karl Marx.

Tao Hua Yuan:
Otherwise known as “The Tale of the Peach Blossom Spring”, this book is considered the quintessential utopian book by Chinese scholars and historians. Written in 421 CE by Tao Yuanming, it is an epic poem of how a traveler accidentally discovers an ethereal paradise where people live an idyllic existence, unaware of the world outside their walls.

Written after the collapse of the Han Dynasty, a period marked by civil war and unrest, this poem tells the tale of how a fisherman sailed up a river that was entirely surrounded by blossoming peach trees. At the end of the river, he finds a village where the people, thought surprised to see him, welcome him and treat him as one of their own. He quickly realizes that the community is an idyllic one, where people live in harmony with nature and one another.

In time, he learns from the villagers that this place was established by their ancestors during the last civil war when the Qin Dynasty was conquering all of China. Since that time, they have been cut off from the outside world and know nothing of its political shifts and wars. Upon leaving, he is told that it would be pointless to recount his discovery of the village to others. He nevertheless makes a note of the village on his map, but when he tells others of it, their attempts to locate it prove unsuccessful.

In essence, the poem suggest that this place, the idyllic village, was otherworldly, and the man’s voyage up the river was in fact a voyage into the afterlife. It also advances the idea that it is only in being cut off from the outside world that an earthly paradise can exist, and those that leave it will never be able to return. This idea was to have a profound influence on Chinese and Asian culture, no doubt inspiring such myths as that of Shangri-La. In addition, the Chinese expression shìwaì taóyuán, which refers to a remote paradise – and literally means ‘the Peach Spring beyond this world’ – has its roots in this poem.

The Classics:
By the time of the Renaissance (14th/15th century CE), Europeans began to have a renewed interest in classical learning. At first, this consisted of merely adapting and translating previously lost texts from ancient Greek and Arabic to Latin and other European languages. However, by the time of the Enlightenment (18th century CE), European scholars were adapting and expounding on classical ideas, bringing them forward into the modern age with new speculations and examples on how a perfect society could be created, or whether or not one was even possible. It was also the age that the term Utopia began to be used popularly.

Utopia:
Ah yes, the man who gave it a name! Sir Thomas More, otherwise known as Saint Thomas More, was a Renaissance humanist and THE man who brought the word Utopia into modern usage. Written in 1516 CE, his seminal study on the perfect society has influenced all subsequent generations of social critics, employing social criticism, history and of course, delicious irony to make a series of points about the ideal society and whether or not it can even exist.

The story is told (much like Plato’s Republic) as a dialogue between the author and a fictitious man named Raphael Hythloday, a world traveler and tradesman. In the course of recounting his tales of all the places he’s seen he brings up one in particular place, the island nation of Utopia, which he hails as the best of all possible societies. As the story goes on, he details exactly what it is that makes it an ideal place, and by comparison, all others flawed.

To break it down succinctly, the Utopians do not value gold and silver because they long ago discovered that there worth is merely an extension of their rarity. Instead, they choose to value iron and bronze as precious and keep jewels, gold and silver in reserve in case they need to bribe foreign princes or armies. In addition, their economic activity is based on an egalitarian principle, where all people rotate from one service to another so that no sense of class hierarchy ever becomes permanent.

What’s more, when it comes to education, the Utopian have made it manifest that all people be taught to read and educated on basic matters of logic, philosophy, numeracy, etc. This is to prevent the creation of a philosopher caste which is concerned solely with matters of thought while others toil away and provide for them. Much like with their policy or rotating labor, it is customary that all people divest themselves from their tasks every now and then to pursue matters of art, science and other intellectual pursuits.

And of course, politics, property ownership, and all other forms of activity on Utopia are considered communal. There is no such thing as private property, rule is exercised by council and not by kings and a court, and membership in this council is rotational, popular and considered a civic duty. In short, Utopia is an ideal society because rule by the few, greed and ownership are all forbidden. And though there are few laws to speak of, all of these practices are contained within a strict code of conduct which was passed down by the island’s founder, King Utopus.

And last, but certainly not least, is the issue of religious tolerance. Written during the time of the Reformation Wars, More claimed that in this ideal society, no one’s faith was ever held against them. Provided they believed in a higher power, no discrimination or persecution were allowed under the law. However, there was one exception, which applied to atheists (!). Essentially, it stated that anyone who did not believe in the hereafter, where they would be answerable for their sins, would be allowed to hold public office.

In the end, Hythloday claimed that there was no reason why other nations could not adopt these same principles which benefited the nation of Utopia so. The only reason, he claimed, was because all other nations of his day were “conspiracies of the rich” where enlightened reform is avoided because of greed, vanity and pride. Ultimately, More chooses to disagree with this fictitious character on numerous points as a way of distancing himself from the critique.

In addition, there are several ironic points which seem to indicate that he was also questioning whether or not such a place could even exist. The name Utopia for one translates from Latin to mean “No Place”. In addition, many of the customs he describes sound less than ideal and would seem to suggest that the only way to create a perfect society is to force people to comply with strict rules, which in turn can create its own problems. In the end, it was not clear if More was saying that such a place does not exist, could exist, or will never exist. All that is clear is the influence it had, once again by expounding on the virtues of collectivization, popular sovereignty and the removal of class distinction.

Gulliver’s Travels:
Though I included this novel in my previous list as an example of dystopian fiction, there are many elements of Gulliver’s Travels that fit into the category of utopia as well. For example, between every voyage Gulliver undertakes which brings him to a land that parodies some aspect of English and European society, there is a corresponding trip to a comparatively idyllic place.

After traveling to the land of the Lilliputians, a land of moral midgets who’s size matches their outlook, he travels to the land of Brobdingnagians where the same rule applies, only in reverse. Whereas he was denounced by the Lilliputians for not helping them to subjugate their neighbors, to the Brobdingnagians he was considered a novelty and his own moral outlook was received with horror.

In addition, after traveling to Laputa, Balnibarbi, Luggnagg, Glubbdubdrib, and Japan, all of which are seen to be inherently flawed in some respect, he travels to the land of the Houyhnhnms. These horse people, who boast rational capacities that put humanity to shame, are seen as the perfection of nature whereas humans are seen as brutish. What’s more, Gulliver’s time amongst them makes him inherently sympathetic to them, but in the end they deny him the right to live amongst them since they see him as a danger to their civilization.

Ultimately, Swift did not give any details as to how the morally upright societies which stood in contrast to his parodies achieved their current state. But by including them in his story, he was employing a decidedly utopian tactic – using a fictitious, ideal society to point out the flaws in an existing one.

Erewhon:
Also known as “Over the Range”, this novel by Samuel Butler is renowned as a prime example of utopian literature (though there are some dystopian elements as well). Published in 1872, the bulk of the story is an account of the fictional nation named Erewhon which is located within the mountains of New Zealand. Often compared to Gulliver’s Travels and Letters from Nowhere (1890) the tale is about a seemingly perfect society which proves to be less than all that.

In describing Erewhon, Butler paints the picture of an idyllic society where people live close to the land. There is also no machinery because the people of Erewhon fear that it will someday become intelligent and supplant them – a rather unique take on Darwin’s theory of evolution and natural selection.

However, in time, the author notes several odd customs in this land involving their justice system, religion and system of coinage. For example, criminals are treated as invalids in their society, whereas invalids are treated as criminals. In addition, religious institutions offer their own coinage and act like banks, but are immune to charges of counterfeiting because they are religious institutions. These practices were meant to satirize certain aspects of Victorian society at the time, including its religious hypocrisy, intolerance and anthropocentricism.

Clearly inspired by other utopian writers, Butler even went as far as to borrow a page from More who was also ironic with his choice of title. The name Erewhon, an anagram for “Nowhere”, makes the deliberate point that this society is fictitious, and therefore its better elements are not to be found anywhere. Though by no means a dystopian story, it is nevertheless a poignant allegory for the British Empire during the time of writing, an empire that for all intents and purposes did not live up to its own ideals.

Modern Examples:
Though by no means as popular as dystopian literature, utopian novels were still a very common feature in the 20th century. And like dystopian lit, it was used repeatedly by authors to mock and satirize the world of their day. By showing a society that had overcome mankind’s traditional flaws, some sought to demonstrate how society could be bettered. Others, however, liked to juxtapose the belief in a perfect society with the reality of an imperfect one, as a way of demonstrating how the quest was noble but was sure to encounter problems.

Men Like Gods:
Published in 1923, this work of science fiction by the venerable H.G. Wells explores an parallel universe where human beings live in a world without government.  Much like the time machine, the book contains equal parts speculative science and social commentary, involving a world in the future that parodied his own.

Taking place during the summer of 1921, the story opens with a cynical English journalist named Barnstaple who is mysteriously transported through time to an alternate world named (interestingly enough) Utopia. Essentially an advanced Earth, Utopia is three thousand years ahead of humanity, where people live in a perfectly realized anarchy, no government or sectarian religion exist, and scientific research flourishes.

All Utopians live by the “Five Principles of Liberty”: privacy, free movement, unlimited knowledge, truthfulness, and free discussion and criticism. After a month of staying amongst the Utopians, Barnstaple asks if he can stay amongst them but is refused. According to the people of this world, the best thing for this journalist is to return to his world. This he does, renewed of vigor and committed to the “Great Revolution that is afoot on Earth; that marches and will never desist nor rest again until old Earth is one city and Utopia set up therein.”

This was not a political revolution, in Well’s eyes, but rather the march of progress which he felt was already very much at work in society. In essence, such a revolution that was guaranteed by scientific and rational progress, he surmised, would one day wipe away all the current problems of the world. Namely, petty nationalism, sectarian turmoil, and irrational fear.

Childhood’s End:
Released in 1953, this story is perhaps Arthur C. Clarke’s best known novel outside of the Space Odyssey series, and the one which established him as a writer. Embracing many themes which would show up in numerous sci-fi franchises, the book deals with the near-future possibility of contact with an alien species and the profound effect it will have on humanity. Broken down into three parts, the book begins with the arrival of aliens, moves onto the effect they have, and concludes with the aftermath of their experimentation and their departure.

The story opens with the introduction of the Overlords, a space faring race that appear suddenly in orbit around Earth in the late 20th century. With their ships poised over every major city on Earth, they issue a simple directive: End all war, now and forever. They assume a sort of indirect control over human affairs, preferring to stay aboard their spaceships, and communicating directly with only the Secretary-General of the UN.

Though many suspect of them of malicious intent, the Overlords influence is largely indirect and they promise to reveal themselves in 50 years. In the meantime, the suppression of war leads to a sort of golden age where prosperity flourishes, but at the expense of creativity. When 50 years is up, the demon-like Overlords emerge and begin conducting some seemingly benign psychic research.

Generations pass and humanity grows antsy due to a general feeling of stagnation. However, many children begin to be born who demonstrate telekinetic powers. Finally, the Overlords reveal that they are representatives of what is called the Overmind – a vast cosmic intelligence created from alien races that have all shed matter’s restrictions and become cosmic beings. The Overlords, for whatever reason, cannot join the Overmind, so they act instead as a bridge, seeking out intelligent life and fostering cosmic evolution. Humanity is now set to join this intelligence, having become post-human and ready to embrace their full potential.

Though some would see this concept of Overlords, Overminds, and tampering with evolution as a negative, Clarke presented it as an unequivocal positive. To him, the idea that humanity would need to be forced to become enlightened seemed like a perfectly plausible means of overcoming its inherent flaws. This is in keeping with Clarke’s Futurist mentality, where progress is not only inevitable and desirable and human antipathy towards progress is based on irrational fear.

The Dispossessed:
Published in 1974, this novel is one of several  utopian science fiction books published by famed author Ursula K. Le Guin. Written during the Vietnam War, the story takes place in a distant solar system (Tau Ceti) where two empires with diametrically opposed views become engaged in a proxy war when a neighboring state undergoes a revolution.

Set in the same universe as her critically-acclaimed story Left Hand of Darkness, the Tau Ceti system consists of two major worlds – Anarres and Urras. Urras is the focal point of the story, a planet which is dominated by two major nations which are rivals. The A-lo nation (which represents the US) is capitalistic and patriarchal whereas the Thu nation (Soviet Union) is run by an authoritarian regime that claims to rule in the name of the proletariat.

To complete the analogy, both states become embroiled in a war when an underdeveloped nation named Benbili experiences a revolution which prompts both sides to invade. Thus, Benbili comes to represent South-East Asia at the time of the Vietnam War, just as Urras represents the world at the time of writing – a world divided between two diametrically opposed empires, both of whom seem to think they are the example of a perfect society (or as close as one can come to it).

As the story goes on, we learn that Anarres, the other major world, was settled long ago by a group of proto-Anarchists who left Urras to escape the planet’s divided nature. Since that time, the Anarrean people have created an egalitarian society which maintains contact with Urras only through its capitol-city spaceport. In keeping with the story, this alternate planet can be seen as a third option for humanity, which finds itself otherwise torn between two extremes.

This calls to mind Brave New World, where Huxley had created a planet torn between madness and insanity, or primitive freedom and “civilization”. In the end, the character of John the Savage, a man who had a foot in both worlds, could not reconcile himself to either and killed himself. Huxley had long expressed regret with this outcome, thinking that he should have offered a third option in the form of the exile communities that dotted the world in his story. Seen in this light, Dispossessed seems to offer solutions to the problem of two civilization fighting over who’s “utopia” is better.

Ecotopia:
Published in 1975, this novel is considered a pre-eminent work of utopian fiction and a fitting commentary on the green movement and counter-culture of the 1970’s. In it, author Ernest Callenbach describes a new society which has been founded in the Pacific Northwest by groups of ecological secessionists. Interestingly enough, his critique of this fictional society was based on environmental science and descriptions of actual communes that were being established across the mid-western US at the time.

Set in the year 1999, the story takes place from the point of view William Weston, a reporter named who is the first American to travel to the new country of Ecotopia. Most of the narrative consists of his cables back to the fictitious newspaper he works for, but other details are filled in by his diary entries. These include an affair with an Ecotopian woman, an experience which leaves him transformed and opens him up to the Ecotopian way of life.

Amongst the differences he notes between his world and this ecological utopia are the policies of universal health care, liberal cannabis use, fitness, local art and fitness (as opposed to television and spectacle sports), sexual freedom, and voluntary mock warfare. Curiously enough, they also celebrate gender roles and believe in racial separation. Not sure how those are meant to be utopian, but okay…

In the end, the narrator comes to see that the Ecotopians are not a backwards, regressionary people but simply individuals who want to live a healthier existence closer to the Earth. In addition to using modern technologies, provided they are ecologically friendly, they also maintain an advanced arms industry and stockpiles of WMD’s, a means of ensuring that a potentially revanchist US government doesn’t try to take back their territory by force. In the end, Weston chooses to stay in Ecotopia and act as a sort of cultural liaison to the outside world.

Aside from the issues of gender roles and racial segregation, this book seems to fit the description of an ideal society quite well. By demonstrating that a better life need not mean huge sacrifices or the denial of technology, Callenbach was basically arguing for an open mind when it comes to the ecological and social experiments which were taking place in the US at the time. His idea of an outsider coming to respect and embrace this culture also calls to mind More’s Utopia and Gulliver’s Travels, where the narrators did the same. He also seems to be arguing that a better society is not only possible, but within our reach.

The Giver:
Although classified as a dystopian novel by some, this 1993 piece of YA fiction has undeniably utopian elements, and therefore confounds simple classification. Taking place in a fictional community where pain and strife have been eliminated through “Sameness” and people’s roles are selected by a council of elders, The Giver begins as a description of a utopian society which gradually becomes more dystopian in its outlook.

Enter into this world Jonas, a young boy who has been selected by the elders to serve as the next “Receiver of Memory”. This person occupies a venerated position in their society since they are responsible for storing all memories that predate Sameness, just in case they are ever needed to aid in the decision making process.

As Jonas receives these memories, he comes to understand just how powerful knowledge is. People in his society are happy, but only because they are ignorant to any way of life that runs counter to their own. In the end, he faces a terrible dilemma. On the one hand, he could release the memories and enlighten his people, though it will surely mean chaos. On the other, he can keep them ignorant, thus ensuring stability for the time being.

Written for young adult audiences, but intensely mature in its outlook, this story not only examines what it takes to create a perfect society but what the costs of that might be. It is also very poignant in the way it addresses a theme which is crucial to growing up – how the end of innocence is a necessary step to becoming a mature and responsible individual. This is a step we frequently wish we could avoid, but seems inevitable in the long run.

Final Thoughts:
Looking at the extensive list of utopian fiction that has been produced across time, I am once again reminded of just how closely linked it is with dystopian fiction. It seems that all utopian commentaries emerged out of a problematic world, where authors felt the need to offer up a better or even ideal society as a means of satire or consolation. Though they differed in that they were not quite cautionary in nature, they shared the same basic purpose as dystopian tales. At once, they offered people a chance to examine this thing we know as the human condition and ask if something better were truly possible.

Overall, I’m not sure which I like better. When I was penning the article on dystopian literature, I could honestly say I preferred it because it seemed more realistic. Now, I wonder if there is not a profound sense of genius and realism to utopian literature that I was perhaps overlooking. Sure, one could make the argument that works like the Republic and Utopia were simple in their intent, claiming that society could be turned into a model of justice and fairness through basic reforms. But upon closer inspection, one sees the unmistakable presence of irony. In all cases, it seems like the author is agonizing over the question of whether or not such changes are even possible.

Sure, greed could done away with if collectivization were enforced. Sure, if money were abolished, there would be far less in the way of crime. Sure, if people were made to rotate between professions, there would be less class conflict and snobbery. And of course, if government were truly representative and those in power were closer to the governed, there would be less abuses of power. But how do you go about making that happen? How, without resorting to force or Draconian measures, do you get people to treat each other as equals and respect each other.

Like it or not, the question “can’t we all just get along?” has been dogging humanity since the beginning of time. Many solutions have been suggested, like the expropriation of the ruling class, a certain means of production, or a certain way of living. But inevitably, all these proposed solutions get tied up in moral considerations (i.e. killing is wrong), or questions of practicality – i.e. getting rid of all the cars, central heating, AC and electricity will lead to millions of deaths worldwide. So really, is utopian literature meant as a proposition for change, or is it merely a tool to make us contemplate the tougher questions?

I know my answer, but in the end, the point is simply to ask, isn’t it? It’s the exploration that counts, which is precisely why such literature has been penned over the centuries. Waiting for heaven to come might be a pain in the ass, but trying to make it come can also be a ticket to hell!
