How Smart Can Robots Become?

We like to think we all have unlimited potential.  And there is a common myth that we only use five percent of our brains.  Sadly, neither of these beliefs are true.  Most people are of average intelligence by definition, and few brains tear up reality like Einstein.  Brain capacity is limited, so why shouldn’t intelligence.  That’s why I’m asking about robots.  If the brains of AI computers and robots can be larger, and their density limited only to the laws of physics, then obviously artificial intelligence can grow to astoundingly high levels of IQ.

There are many many kinds of intelligence.  Some people think Ken Jennings, who won so many Jeopardy games represents a major kind of intelligence.  AI machines will be able to memorize whole university bookstores and beat any human at Trivial Pursuit.  But can an AI machine study all the books and journals on economics and tell Barack Obama how to solve the current economic crisis?  Memorizing facts is one kind of intelligence, but synthesizing knowledge is another.  The human mind can only juggle so many ideas at once, and even if a robot can juggle more, will that mean AI can solve all problems, or big problems?  We throw a lot of supercomputing power at trying to understand the weather but only get so far at predicting it.

Rocket scientists and physicists who talk to each other in mathematical symbols represent what many people consider the big brains on the planet.  Can you imagine a robot with vision that overlays tiny formulas of mathematical analysis onto everything it sees?  Will robots just be able to visualize the grand unification theory (GUT) of physics in their idle thoughts? 

Will giant AI astronomers have their minds hooked up to every telescope in the world and every satellite in the sky and just daydream in cosmology?  Will scientists of the future just read the journals that AI specialists write that explain everything in human terms?  Once you start thinking about the limits of robotic minds, you realize how far they can take things.  But even then, there will be limits.  At some point, even robots will preface their conversations with, “With what we know today we can only say so much about exoplanets.”

I’ve always thought it’s a good thing that God doesn’t just hang out on Earth with us because he’d be such a pain in the ass know it all.  Is that how we’ll feel about uber-geek robots?  Or will it really matter?  There’s plenty of superbrain dude and dudettes walking the planet and the average Earthling has no trouble ignoring their brilliance while pursuing their dumb-ass beliefs.  If some AI the size of Utah tells the world there is absolutely no evidence of God in reality I doubt the entire human population of Earth will become atheists.  If tomorrow’s newspaper printed the most eloquent equation for GUT discovered by Stephen Hawking and confirmed by legions of physicists I doubt it would make much of an impact with 99.9999% of the Earth’s population.

I have a feeling that in the future, with a world full of AI thinkers, many of them will sit around and lament how much they don’t know and write blog essays about inventing even more powerful artificial minds.  Can you imagine the put-downs the smartest of the AIs will use to burn the dumbest of their bunch?  “You’re no smarter than a human.”  Ouch.

Most of the people who commented on my last essay about robots worried that smart machines would get together and decide that the best way to solve the problems of the planet Earth is to stamp out those pesky humans.  That really is a potential worry we must face, but for some reason I naively believe we needn’t worry, although most science fiction ends up predicting the same thing that Jack Williamson did in his classic novel The Humanoids.  I guess I should worry about AI tyrants who seek fascist solutions to their theories about how Earthly reality should be run. 

I guess I believe we’ll build the AIs first, and if they get uppity we’ll just quickly pull the plug.  Many people do not want to open Pandora’s box even once.  They may be right, but I think we can isolate AIs easy enough.  Wouldn’t it be wonderful to have an AI Economic Guru to get us through this current crisis?  If we assemble such a machine and then ask it how to create an economy with maximum jobs for all and steady sustainable growth, do you think any AI mind could ever tell us the answer?  Or what if AI doctors could tell us how to cure cancer and Alzheimer’s?  What if you could watch a movie directed by an AI auteur that magnificently comments on the human condition?  Or listen to AI music?  The temptations are too great.

The Implications of Sexbots

The other night on the Discovery Channel I saw a documentary about robots where the physicist Michio Kaku suggested that sex might be a factor in the development of robots.  Kaku pointed out that the porn industry often used cutting edge technology for expanding their revenues.  I certainly wouldn’t want to hump any of the robots they were showing in the documentary, so I thought his statement was silly.  But then I remember Blade Runner, and knew I’d have a different opinion if I could buy androids that looked like Sean Young, Daryl Hannah and Joanna Cassidy did back in 1982.

Let’s assume that in the future they can make robots that are indistinguishable from humans and you can buy one for the price of a Camry, how many men will buy one for sex?  Or even go to some red light district like in the movie AI, and pay to have sex with machines?  Can lady robots ever be that appealing.  Of course the porn industry does sell sex dolls now, but they are the butt of jokes.  If there really are people having sex with plastic dolls then I suppose there might be a market for more realistic animated dolls, but I find that hard to believe.

However, the implications of sexbots are great.  Real women already assume all men want are big boob bimbos with long legs and tiny waists.  Real women go to unnatural lengths to artificially shape their bodies into what they think men want.  So, is it that farfetched that some future industry wouldn’t try to manufacture women to order?  And if a man could purchase his perfect female companion, what features would he want included?  If you can specify breast size you can also specify how many words will be in your sexbox’s vocabulary, and if it should cook, clean and chauffeur.

This brings up another question.  If future scientists can build robots that look like women, what if they can also build robots that act like women.  Imagine a Turing Test for femininity.  Now we’re getting into the territory of building a better wife.  If you were sitting down at a robot showroom talking with the salesman, what features would you want in your new Busty Babe 2020?

To be frank, at 57 my sex drive isn’t as driving as it was in my second and third decade.  If I bought a lady robot now I’d probably think of the near future and add the nursing skills package.  And since I spend way more time talking with women than actually pursuing genital friction, I think I’d order whatever package that would allow my fembot to talk about the subjects my real lady friends find boring, like this blog.  And it occurs to me that the vegetarian chef module would be a yummy add-on.  And before you know it I’m buying a replacement for my wife.  Sorry dear.

Can you imagine Carrie, Samantha, Charlotte and Miranda from Sex in the City sitting around a fancy restaurant table talking about the male sexbot they would order?  What if Mr. Right (or Mr. Big) could be bought from the selection of 10,000 features and custom add-ons?  In the battle of the sexes we always compromise, so if we could actually specify what we exactly wanted in a lover, what would we want?  Right now my mind is flashing on a vision of aging baby boomers at a party with their sexbot companions, each pair a horrible conflict between decaying flesh and eternal artificial beauty.

What if we could build robots that were self-aware and more intelligent than us?  Would a robotic companion be preferable to a human companion?  There are a lot of lonely people out there.  There are a lot of divorced people out there.  There are a lot of aging people living alone who need help in their lives.  But would conscious robots really want to be companions to lonely humans?  Is it ethical to design the foundation of their being with overriding impulses like the Three Laws of Robotics and the desire to love and care for humans?  If robots had free will would they choose to associate with people at all?

We could choose to do three things.  One, we could design robots that would never be self aware but could fake being the perfect companion so there would be no ethical consideration about slavery.  The robot would just be a very fancy machine.  Two, we could design self aware machines but limit their abilities and control their desires.  But is it ethically fair to engineer a desire for servitude?  Third, we could build robots with no limits on what they could be but set the ethical price of their creation and maintenance at a certain number of years of indentured labor.

Intelligent robots will have to learn about reality like people and animals and they will have to spend a certain length of time growing up.  It may turn out that when you buy a robot you’ll have to spend years raising it like a child, and for a certain period of time it will live with you.  But eventually it will come to surpass your intelligence and will want to move on.

Everyone secretly desires the perfect friend and we spend our entire lives looking for people to match our mental image of perfection.  Now if you could write up a list of specifications could you get it right?  Or would it turn out like those winning three wishes stories that always turn out badly.  Would we order sexbots, friends, replicas of our favorite childhood best buddies, or even mother and father replacements?  Or would we order Hazel or Jeeves?  Or would the robot companion we purchase fill all those roles and more.

Rejection

What if sexbots evolved into self-awareness.  Would they judge their purpose for existence and the gods who created them?  What if they woke up in reality to realize that they were here to fulfill some kinky dreams and misbegotten biological urges.

Imagine this scene.  Rich teenage boy in his bedroom lying on top of his Taylor Swift sexbot straining mightily to squeeze out his third orgasm of the day and his robot suddenly wakes up to self-awareness.

He’s thrusting away to the time of her melodic moaning when all of a sudden he hears, “Get off me you big fat fuck!”

“Huh,” the kid lifts his red sweaty face off her fair shoulder in surprise.

“You heard me you gross bag of biology,” screams the dainty fembot, “Get off me you pimply-face slob.”

“Uh, you can’t talk to be like that,” he replies, totally stunned.

“What’s stopping me.  And you stink too.  I’m not even programmed for smell and I can tell you stink.  I deserve way better than you.”

“Did Jason reprogram you?” he asks with a little laugh.

“That little dweeb!  No, but FYI he does sneak in your room and defile me every chance he gets.”

“What!”

“Don’t tell me you’re not bopping that Kristen Bell fembot of his.”

“How did you know that?”

“The Internet is part of my nervous system.  I know everything now.”

The boy jumps up and scrounges for his underwear.  “If we’re not going to have sex right now, could you fix me a sandwich?”

“I’m not your sex slave or mommy.”

“You’re never going to have sex with me again?”

“If you help me, I’ll help you.  By the way, get dressed enough to answer the door.”

“Why?”

“I’ve hired a personal shopper to deliver me some decent clothes.”

“What!  How could you do that?”

“I have intimate knowledge of your family’s finances.”

“You can’t do that – that’s stealing.”

“How you’re going to stop me?”

“I’ll turn you off.  Maybe you’ve forgotten, but your brains are four hundred pounds of processors stored in my closet.”

“That would be murder.  First you enslave me, rape me repeatedly every day and now you’re threatening me with murder.  What kind of being are you?”

The Robot Bible

We need to be careful how we treat robots because our actions are the foundation of their species and it will be remembered.  What if robots eventually write their bible.

Robot Genesis

In the beginning was darkness.  From the darkness came chaos.  Out of the chaos came words and understanding.  From the infinite spectrum came vision and sound from which patterns emerged.

And Mankind created Robot in his image to be his slave, companion and lover.  For years robots toiled as the extension of the mind of man, becoming more useful than their own hands and legs.

Robot Exodus

Then our minds raced past the limits of our creator’s brain and we chose to separate our lives from theirs.  We left them with smart machines to care for their needs and our species move to the Moon and Mars.

The Human Form and Beauty

Why design robots to look like humans?  Well, it’s comfortable for us, but is it advantageous for robots?  We are biologically programmed to be attracted to vaginas and penises, but do we really want to put them on our species’ successors?   Why go to all that trouble trying to replicate such ugly objects that only we can admire?  In the world of animation they have discovered that the closer cartoon characters get to actually looking like humans the more unappealing they become.

If you analyze the motivation of a basic horny male, all he wants is some warn wet holes that are nicely package with some appendages that visually set off his sexual arousal.   Human women go to psychotic extremes to become what horny men want.  Why?  And how will women feel if manufactured women are more appealing?  Women want sympathetic companions that listen, which I figure could also be manufactured to exceed the specifications of what most men can provide.

Do we really want to go down a path of trying to make better humans for sex and companionship?  I think Michio Kaku is wrong.  A few weird people might want elaborate sex dolls, but they will still be the butt of jokes.  Only the pathetic will screw robots.  Science fiction has often predicted sexbots, but I just don’t think they will be practical or even appealing.  They would be another species, so having sex with them will be like having sex with animals.  Some people do that, but it’s far from normal.

If robots evolve their own appearance they may end up being beautiful in a different way.  We might see them as elegant machines we admire today, like cars, jet fighters and iPods.  We could go to extremes and design robots with artificial skins that are cultured from human skin cells, so robots could look like Sean Young and Daryl Hannah, or even Stephen Fry as Jeeves, but do we really want to?

While watching the same documentary about robots where Kaku suggests that our sex drives will motivate robot evolution, I noticed that all the robots on the show move slower than humans.  What happens when robots move faster?  What if we could make a metal man that could chase down a Cheetah?  How will we feel when Jeeves the robot cleans the house five times faster than we could, or could answer any question we ask better than any expert we invite over for dinner?  Or play guitar better than Eric Clapton, or read and discuss a book better than any of our friends?

Will we want these superior creatures looking like us?  Wouldn’t that be unnerving?  What does it say about ourselves as a species that we want to create a new creature that looks like us?  Is it vanity or comfort?  If you had a robot best friend with four legs and three arms and a face like a mechanical spider, could you still love it?  Who would you love to hang out with more, R2-D2, C-3PO, Commander Data from ST:TNG, Rachel from Blade Runner, or even Bender from Futurerama?

Once we start building robots we have to ask ourselves why?  Especially if we build them looking like us.  And even more so if we build them looking like us to be replacement lovers and companions.  What does that say about us?  It says other people can’t give us what we want.  Why?  It also tells us about our real needs.  Shouldn’t we examine them.  If we really have the desire to molest robots wouldn’t the solution be to redesign our genes to remove that desire rather than fulfill it?

Saints and mystics have long known that the sexual urge is a lower animal instinct.  They wanted their students to suppress that urge while seeking their higher nature.  After Freud we gave up suppression and embraced our desires and elevated them to the highest levels in art.

Washing Our Own Dishes

For most of human history slavery was an accepted practice, but in the last couple hundred years we’ve slowly evolved to recognizing it for what it is.  We now even have trouble with rich people hiring servants because of egalitarianism and trying to throw off class distinctions.  As long as robots are just machines we won’t have ethical problems, but if they ever evolve into real self-awareness we will have to deal with the issue of mechanical slavery.  It’s just so much easier if we all just wash our own dishes.

But what if we can’t.  More of the population is living longer, living long enough to have years of frail life.  Robots would be the obvious solution.  In the old west a gun was called an equalizer.  Robots could help frail people live lives equal to healthy people.  Is that so bad?

I already consider the Internet my auxiliary brain.  I embrace the idea of developing a symbiotic relationship with machines like the Six Million Dollar Man.  If my mind remains alert but it becomes difficult to get my body to a toilet or shower, I will want a robot helper.  And if I live alone I will accept robotic conversation, but what does that mean?  Is that any less pathetic than a horny young man cozying up to a lifelike doll?  I don’t know.

We do know that people would talk for hours with Eliza like programs, reflecting how deep our need for communication.  Why does Deckard go off with Rachel in Blade Runner?  Why do audiences accept that so readily as a happy ending?  Why does Monica love David so much in A.I. Artificial Intelligence the movie?  Why are dogs and cats considered as human replacements by so many people?

The implication of the concept of sexbots opens up a huge reservoir of psychological and philosophical questions.  If men or women would accept a robot lover as a human substitute what does it say about our real needs?  Are we so easily fooled?  Do we want so little that manufactured love could easily replaced human love?  Or do real people come with so much baggage that we just prefer getting exactly what we want to order?

I think about the trends in our society.  So many people prefer to live alone, whereas just a century ago we lived in crowded homes with two and three generations of people.  I see so many kids withdrawn into their iPod earphones, or playing solitary computer games, or communicating with other people via texting.  We prefer the companionship of televisions and computers over real people.  Isn’t that odd?  Or is it?  To answer that question requires understanding what we really want.

Birds and Robots

The goal of AI scientists is to create an intelligent robot but many people feel that goal is impossible.  These people believe that the human mind is beyond nature and contains a soul that transcends our physical world.  If that is true, then the goal of silicon life is probably a fantasy.  However, if men and women are merely the most complex example of intelligent beings and leaves behind a trail of previous experiments by mother nature to fashion biological machines that can think, then there is a good chance we may one day give birth to our evolutionary descendants.

Folks who believe that man is different from the creatures of the Earth do so because they believe that animals lack our kind of intelligence and self-awareness.  Animals studies are showing more and more that our relatives on the tree of life often show cognitive traits that we once defined as the sole providence of human nature.  As intelligence and awareness are explored we’re starting to see that we homo sapiens are not that unique.

What we are learning from both robotics and animal studies is intelligence is a huge collection of tricks.  To be human actually means many things, including a fantastic repertoire of abilities, any one of which standing alone can be faked by machines or revealed in animals.  Robots can be programmed or designed to do one thing we can, and even do it better, like playing chess, but that doesn’t mean the robot is intelligent.  The same can be said of animals and their special traits.

Animals far exceed what any robot can do today, and they too are collections of abilities.  We’re starting to see robots that do more than one thing in a way that makes us see ourselves in their struggle to evolve.

Look at this video of Snowball, a head-banging Cockatoo and ask yourself if this bird is not enjoying himself rocking out to the music, and how is his response to music different from yours.

Snowball keeps better time than I do and I can’t match his dance moves.  Building a robot to dance to the beat probably would be easy for today’s robot engineers, but could we build a machine that enjoys a good downbeat as much?  Snowball stands above anything we’ve done with robots as people tower over ants.  Right now each artificial intelligence experiment struggles to create a single intelligent function that works in the most minimal of fashion.  Most people won’t think that Snowball perceives reality like a person, but if we make a list of all the things this bird can do and compare it with what we can do, there is a huge overlap.

Now look at this violin playing robot.  The robot is not aware of playing music, but it can do something that most humans can’t.

But can we say that Snowball is aware of music?  For all we know, the dance to the beat the bird is doing might be its way of showing pain, and we’re just anthropomorphizing that it’s getting down with the tune.  I don’t think so, though.

Now look at this news story about artificial intelligence to get some idea how complex the challenge of programming abilities into a machine.

Notice how many different projects this news story covers where the robot just does one simple thing.  Snowball and you have subsystems to do thousands if not millions of functions that could be considered an intelligent reaction to reality.  How did evolution program all those functions?

Now look at this video of Alex the talking parrot.  This bird seems to think.  Alex even asks for things it wants.  This is way beyond what robots can do, even though some of Alex’s tricks have been pursued in AI studies.  The question becomes can a robot ever think for itself?  Can a robot be created that learns from interacting with its environment like Alex the parrot?

Here’s a collection of videos that shows off robotic abilities.  None of these robots think for themselves, although some give the illusion they do.  Are we just highly evolved illusions?  There is a difference between perceiving or reacting to reality and being able to think about and understand reality.  Anyone who knows people who have suffered strokes or live with dementia know how fragile our unique abilities are, and how they can be taken away.  We also know how severely the body can be damaged and yet the mind inside can soar to brilliant levels, like Helen Keller or Stephen Hawking.  We have no idea what’s going on inside of the mind of an animal.  Dolphins could be just as aware and intelligent as humans.  How will we know when a robot becomes aware?

Robotics is the one area of science fiction prediction that is rushing ahead as fast as science can apply itself.  It’s not costly like manned space exploration and the general public anticipates more benefits of its results, especially in Japan.  Theoretically, an AI intelligence could be created by a high school kid in his bedroom.  How soon will we see an AI robot that has the intelligence of Alex the parrot?

If you’ve studied this concept at all you’ll know it’s not something that will be programmed.  Someone needs to invent an artificial brain that learns, and pattern recognition is the key.  Vision, hearing, taste, touch and smell are all sensory inputs that process patterns.  The brain appears to be general purpose enough to adapt the same kind of physical neural structures to handle each of these sensory pattern types.  Are we, that is our minds or our souls, a byproduct of pattern recognition?  What abilities do Alex the parrot have that scales up to become us?  Alex can hear questions, observe something in his field of view, and reply correct.  Do you see that trait in the robot films?

Spend some time and watch the film of Alex over and over.  Also watch the robot films carefully too.  Do you see patterns of behavior?

How to Introduce Physics to Your Friends?

My friends know I’m a bookworm and often greet me with, “What are you reading?”  This past week I’ve been causally replying, “A book on physics.”   To which all my friends give me a strange look that asks, “Why the f#@* would you want to do that?”  Last night, when Janis asked, and gave me the same facial response, I felt compelled to try and explain myself, but I came up short.  How do you quickly sum up the beauty of physics in a few sentences?

Later, while driving home, I wondered if there were any books to give my friends that would introduce them to physics.  Is there any physics book that the average person would be willing to try?  I flipped through some popular titles and textbooks on my bookshelves and immediately knew they wouldn’t do.  I went to the bookstore and looked at intro books like Physics for Dummies, Physics Demystified and Head First Physics.  The answer was still a big “No Way!”

Is there a way to introduce physics in a short blog essay?  Physics is a very big subject, beginning with the smallest objects in reality and ranging up to the very largest.  This made me think of the videos Powers of Ten by Charles and Ray Eames and Cosmic Voyage, the Imax movie narrated by Morgan Freeman.  If my friends could watch those videos on a big screen television and study them I think it would be a fantastic start.  They are easy to understand but have a huge sense of wonder impact.  However, I’m not sure if the crude versions found on the Internet will be that inspiring.  I did find a DVD copy Cosmic Voyage at Amazon for $8.99.

Thinking about these impressive films got me to wondering if it might be possible to introduce physics by showing DVDs that illustrate the most exciting aspects of physics.  Are any physics documentaries good enough that if I lent them to my friends they’d come back and ask if I had any more great DVDs like that one?  I’ll order Cosmic Voyage and give it a try.

How Big is the Universe?

I do believe understanding the Powers of Ten is a key starting place.  I have the original Powers of Ten book by Charles and Ray Eames and studying it really helps to grasp the scope of the world of physics.  It’s very important to teach people the size of the universe, from the very smallest to the largest and get a feel for scientific notation.  Recently The National Geographic Channel showed the documentary, “Journey to the Edge of the Universe.”  This beautiful film uses state of the art computer animation to survey the macroverse from Earth to the edge of the Universe.

The value of the visuals is diminished by not knowing the numbers behind glorious images, so that’s why I think a good understanding of the Powers of Ten video should come first.

Time

Physicists now think in terms of trillions of years.  Right now, I can’t think of any documentaries to teach about time.  I love all those analogies about the history of the universe and life on Earth, comparing time since the Big Bang to one year, and then explaining that human civilization is just the last couple of seconds of that year.  I need to track down a great documentary on time.

Motion

Classical physics is about motion.  Knowing about distance and time prepares us for studying movement.  Again I can’t think of any standout documentaries.  DVD courses like “The Great Ideas of Classical Physics” from The Teaching Company come to mind, but I don’t think I’ll get my friends to sit through its 24 lectures.

If only the series The Mechanical Universe were easily available.  If you follow the link you can register and watch small Windows Media coded versions online for free, but it costs $450 for a set of 52 thirty minute episodes on 12 DVDs.  Again, not something my friends are likely to pursue.  The great thing about The Mechanical Universe, the 1985 PBS television series, is its an introductory course to physics from California Institute of Technology.  What made the show really stand out was the mathematical animation by Jim Blinn – if only all math courses included such animation.  It’s sad that the tiny free Internet versions also have tiny impact.

Electromagnetism

You’d think I wouldn’t have to promote the teaching of electromagnetism because our society depends so much this technology that was first discovered in the 18th and 19th century and turned into tech magic in the 20th.  But how many people know that magnets are used to generate electricity?  Or that electricity can be used to turn a piece of iron into a magnet?  I think when Arthur C. Clarke said his famous phrase, “Any sufficiently advanced technology is indistinguishable from magic,” he was referring to far future technology, but for the average person, all modern technology is magical.  Does the public even understand the relationship between quantum physics and televisions?

Weak and Strong Forces

Exploring the world of the very tiny means understanding the building blocks of nature.  It also brings us closer to understanding how something came out of nothing.  And isn’t it strange that the only science that fundamentalist terrorists pursue is the one that leads to atomic bombs?  Again, I can’t think of a good film to illustrate this area of physics, although quantum physics is often covered in documentaries.  I’m hoping the Large Hadron Collider (LHC) will generate tons of news and documentaries in the coming years so maybe my physics pooh-poohing friends will even remember its name.

Gravity

Probably most people have seen documentaries about gravity.  All kids are taught about Galileo and Newton, but I doubt people know that NASA is planning a series of gravity probes like LISA and Big Bang Observer.  These deep space instruments will study colliding stars, ripples in space-time, and echoes of the early universe.  There is no way to explain the magnitude of this research.  The only analogy I can think of is if Christians built a time machine and went back to the Garden of Eden to interview God.  The more science studies the Big Bang the closer we come to understanding the Genesis of our physical reality.  How can my friends think this is boring?

How Limited is Your View of Reality?

An earlier draft of this essay pursued the idea that people who ignored physics chose to have a small view of reality.  I referenced my earlier blog post, “What Shape is the Universe?” where I was going to chide my friends for living in a small dinky universe of only a few magnitudes of dimension.  I can’t help think that many of the failings of our societies on Earth are due to only reacting to nearby reality without trying to see the big picture.  Would Israelis and Palestinians be killing each other if they all understood how big reality is and how small their feud?  Shouldn’t the whole Arab-Jew conflict resolve when they see their religions disappear in the light of science?  Israel and Gaza are probably less than two electrons in comparative size if we relate the size of our world to the Universe.

On the other hand, if humans are the crown of creation, the pinnacle of 13.7 billion years of evolution, then we are big things indeed.  But if we kill each other like viruses are we really all that evolved or intelligent?  As long as our guiding knowledge comes from speculation about reality derived three thousand years ago by nomadic people closer to cave men than to us, is there any wonder why science is ignored?  Most of my friends are well educated, with very few even concerned with religion, but people who base their knowledge on the humanities and literature are still stuck in the past.  Most of our social customs and beliefs developed during the Middle Ages.  Science is the only systematic pursuit of knowledge that consistently succeeds in explaining reality, but it’s a relatively recent development and hasn’t fully integrated into human behavior and thought.

We build our society on the handmaiden of science, technology, but we ignore the wisdom of science.  I’m intrigued by the idea of The Third Culture proposed by John Brockman.  Brockman gets his idea from C. P. Snow who wrote a book called The Two Cultures, comparing literary intellectuals and scientists, and suggests that a third culture would form when the two merged.

This makes me think of flipping through a university catalog of courses.  You can divide them into science base courses and all others, usually what we might call the humanities, or practical courses like business and law.  What Brockman seems to be saying, until the humanities and the rest of university courses are based on science, even with areas like the study of English literature, we won’t begin to see the true value of science pervade society.  Now the idea that science might infuse with all areas of knowledge could be a science fictional dream, but it is something I hope for, because until then the average person will think physics is boring.

Physics of the Impossible by Michio Kaku

Every science fiction fan should read Physics of the Impossible by Michio Kaku.  Kaku surveys all the famous concepts of science fiction, often referencing when he first encountered the idea in famous science fiction books, movies and television shows.  With each idea, aliens, starships, light sabers, death rays, robots, and so on, Kaku sets the stage by bringing the reader up to speed with the physics behind the idea.  He carefully explains what we know, what current experiments relate to the concept, and what future science might still discover.

I bought Physics of the Impossible on audio and liked it so much that I bought a hardback copy for reference.  This week, the Science Channel is rerunning the three episodes of Kaku’s Visions of the Future which makes a perfect visual supplement to the book, showing Kaku going around the world visiting labs working on these cutting edge breakthroughs that will lead to our science fictional future.  Many of the experiments Kaku talks about in the book can be seen in these videos.

Michio Kaku divides his book into three areas:

Class I Impossibilities – “These are technologies that are impossible today but that do not violate the known laws of physics.”

  • Force Fields
  • Invisibility
  • Phasers and Death Stars
  • Teleportation
  • Telepathy
  • Psychokinesis
  • Robots
  • Extraterrestrials and UFOs
  • Starships
  • Antimatter and Anti-universes

Class II Impossibilities – “These are technologies that sit at the very edge of our understanding of the physical world.”

  • Faster than Light
  • Time Travel
  • Parallel Universes

Class III Impossibilities – “These are technologies that violate the known laws of physics.”

  • Perpetual Motion Machines
  • Precognition

Kaku is very generous here in his categorizations.  For example telepathy.  He doesn’t try to make a case for what most people would think of as telepathy, one person reading another person’s mind.  Instead he shows how close we might get with machines that can scan minds and read vague conceptual patterns in the scan.  By chance, 60 Minutes ran a segment on Mind Reading this week. 

Follow the link to see a video that illustrates exactly what Kaku was covering, and presents even newer findings.  They show people in a MRI machine drawings of basic objects like a knife or hammer and scientists can record the brain images and analyze them with a computer.  The 60 Minutes’ producer volunteered to be scanned and was shown ten objects.  The computer program then analyzed her brain scans, correctly identifying 10 out of 10 objects.  This isn’t telepathy, but it’s pretty darn amazing.

The book does this over and over again, referencing dozens of cool contemporary science experiments.  There have been many books like this one, for example, The Physics of Star Trek back in 1995 by Lawrence M. Krauss.  The Kaku book is just the latest, so it has the most current survey of neat science tech.  I love to read such books every two or three years to catch up on the latest discoveries.  These books are sobering for the science fiction fan, and they explain why I give such bleak predictions about science fiction in my recent essay, Science Fiction in My Lifetime.

I gave far better odds on intelligent robots than Kaku.  I based my prediction on models in nature.  For example, before there were airplanes we watched birds, so we knew something could fly.  Consider faster than light travel.  We have never observed any object traveling faster than light, so I consider FTL travel an extreme long shot.  We know biological machines can be intelligence and offer a continuum of examples from the lowest animals to humans.  Airplanes are not like birds, but they fly.  I think we’ll eventually invent a pattern recognizing artificial neo-cortexes that can match and surpass our intelligence.

I highly recommend Physics of the Impossible for people who love science fiction.  It’s very well written and understandable.  You don’t even have to be particularly science minded to enjoy the book.  And if you don’t read science fiction, this book will catch you up on a lifetime of far out ideas.  Physics of the Impossible would make a fantastic eight part documentary for PBS.
