Of Space-Time and Clock Towers

by Len Hart, the Existentialist Cowboy

Brian Greene is an American theoretical physicist and string theorist who has worked on mirror symmetry since 1996 while a professor at Columbia University. As a result, he believes that in “infinite” universes, matter can arrange itself in an infinite number of ways. Eventually, a “universe” is repeated. Such a parallel universe would look very much like the one we live in.

Therefore, Greene says, if the universe is infinitely large, it is also home to infinite parallel universes.
As a string theorist, he believes that apparent conflicts between current cosmology (Relativity theory) and quantum mechanics is resolved with string theory –his 'specialty' for the past 25 years. Greene believes that the entire universe is explained with small strings vibrating in as many as 11 dimensions. Moreover, within our single universe time is relative to where you are and how fast you are going at any given instant.

Therefore, time is always local even within the single universe we live in. For example, time is slower for anyone who is moving. As Einstein demonstrated, time stops for anyone traveling at light speed.

Einstein imagined a street car leaving the clock tower in Bern. As long as his speed was less than that of light, the clock viewed from the street car would appear to be moving forward, marking the 'forward' progress of time. But –should the street car exceed the speed of light, the hands of the clock would appear to go backward as the street car catches up with and passes light beams.

This effect can be simulated with an oscillator or an old 33 and a third RPM album turntable with a disc of concentric hash marks calibrated to appear stationary under florescent (pulsing) light. If the turntable is too slow, the hash marks will appear to rotate in one direction. If the rotation is too fast, the marks will appear to move in the opposite direction. At the desired turntable speed, the hashmarks will appear absolutely motionless. By the same token, time STOPS for one traveling at the speed of light.

The downside is that many other unfortunate things will happen to you at that speed. So –don't try this at home or without the supervision of experts. You are safe if you confine your experiments to an old 33 1/3 RPM turntable and some old Rolling Stone LPs.

A few years ago, Julian Barbour “shook up” readers of “Discover” magazine when he denied the existence of “time”. He may have been correct. In fact, he is consistent with Einstein. Einstein posits that time is merely one's local' movement relative to the speed of light. Young Einstein lived in Bern (Switzerland) where he worked at the patent office. He often took the tram home in a direction away from the famous Bern clock tower. He imagined how the clock might appear should his tram exceed light speed.

He immediately concluded that the hands on the clock tower would appear to move backward relative to the forward movement perceived by pedestrians on either side of the street. The explanation is simple: at faster than light travel, the tram overtakes light that had already left the tower. One looking back at the tower would see the hands run backward.

That, of course, is a dramatic example that drives home the point for anyone daring to imagine faster-than-light trams. The conclusion is simpler: time is different for every person occupying a different space from every other person. For that matter, time differs from every point to every other point in the universe.Barbour believes the past, present and future all exist in what may be called a timeless 'super-verse'. Barbour posits a series of “NOWS” like individual frames on a motion picture film strip. 'Nows' exist for actual events but, interestingly, many 'nows' are alternate possibilities, i.e, virtual universes.

This view is consistent with Einstein's analogy re: the Bern clock tower. To use Barbour's film strip analogy, NOW is a single frame. The universe is the entire film strip. Parallel universes may be compared to alternate "film strips", thus Barbour's views are consistent with Greene's "parallel" universes. If Barbour's timeless universe is akin to a film-strip, then Greene's parallel universes are a shelf full of film-strip canisters –each containing a feature-length film. In this case the feature-length movie is the universe as it unfolds. But as long as we travel at sub-light speeds, we move forward in time as "light" over-takes us. But if we should exceed light speed we will eventually see the big bang! In fact, we can see remnants of the big bang now. This "object", astronomers tell us, is some 13.7 billion years old and as many light-years distant.

The Origins of Artificial Intelligence in English Romantic Poetry

by Len Hart, The Existentialist Cowboy

Ada Byron, daughter of the English Romantic poet Lord Byron is – arguably --the world's first computer programmer. She is otherwise known to history as Lady Lovelace. The case on her behalf is so strong that the Department of Defense developed a programming language in her honor: ADA. It was among the first so-called "Object-Oriented Languages," a set of languages dominated by C++, Java, etc. But that gets ahead of the story by some one hundred years or more.

Ada Byron was born in 1815. Divorced from Lord Byron, Lady Byron brought up her daughter, Ada, fearful that she might suffer Romanticist, "poetical" tendencies as did her father. Her education, therefore, consisted of mathematics and science. Predictably, Ada's understanding of mathematics –though profound –was influenced by simile, analogy, and metaphor.

It is not surprising that Ada was fascinated and intrigued when, in 1834, she encountered Charles Babbage's idea for a "calculating machine" about which Babbage offered a daring conjecture: a machine acting upon foresight.
Most of what we know of Babbage's "differential engine" we have learned from Ada Byron. Inspired by the "universality" of Babbage's ideas, Ada proceeded to write more notes on Babbage than Babbage wrote at all. Her fascination with Babbage's "engine" is noteworthy for at least two outstanding developments.

It was Ada, inspired by Babbage's calculating machine, who first articulated, if not invented, the very concept of "software" –a set of instructions to be carried out by a "universal" machine – a machine capable of acting meaningfully upon those instructions. The obvious progeny of this concept is the multitude of software packages that now drive everything from desktops to mainframes.

Of even greater interest to physicists and cosmologists is that Ada's ideas and hopes for the 'computing machine' lead inexorably to Claude Shannon's concept of information as the inverse of entropy – a western version of the yin and yang. Entropy is or is associated with the Second Law of Thermodynamics, a general principle constraining the 'direction' of 'heat transfer'; in the vernacular: things run down. Chaos increases. Organization becomes dis-organization and disorder. Hot things cool down in the absence of new infusions of energy. Eventually all movement ceases entirely. Some have called it the 'heat death' of the Universe –a final and eternal 'thermodynamic state' in which there no longer exists sufficient 'free energy' to sustain motion or life.

Shannon then spent 31 years at Bell Labs, starting in 1941. Among the many things Shannon worked on there, one great conceptual leap stands out. In 1948, Shannon published "The Mathematical Theory of Communication" in the Bell System Technical Journal, along with Warren Weaver. This surprisingly readable (for a technical paper) document is the basis for what we now call information theory--a field that has made all modern electronic communications possible, and could lead to astounding insights about the physical world and ourselves.

Names like Einstein, Heisenberg, or even Kurt Goedel are better known among the people who have led twentieth-century science into the limits of knowledge, but Shannon's information theory makes him at least as important as they were, if not as famous. Yet when he started out, his simple goal was just to find a way to clear up noisy telephone connections.

--Heroes of Cyberspace; Claude Shannon
Shannon wrote A Mathematical Theory of Communication [PDF] for Bell Labs in 1948 –more than a hundred years after Ada wrote what is considered to be the world's first computer program, a plan that she shared with Babbage. In it, Ada suggested how his machine might calculate Bernoulli numbers. This was the world's first computer program.

The second development began the debate about Artificial Intelligence. In his paper Computing Machinery and Intelligence, Alan Turing, devoted several paragraphs to "Lady Lovelace's Objection" to the very concept of A.I. It was a concept which Ada discounted in her notes:
The analytical Engine has no pretensions whatever to originate anything. It can do whatever we know how to order it to [do]. It can follow analysis; but it has no power of anticipating any...truths. Its province is to assist us in making available what we're already acquainted with.
Some 100 years later Turing ascribes to her a cautious "logical positivism:"
It will be noticed that he [ D. R. Hartree ] does not assert that the machines in question had not got the property [ A.I.], but rather that the evidence available to Lady Lovelace did not encourage her to believe that they had it.
The point is not whether Lady Lovelace or Turing is correct with regard to A.I., but rather that it was Ada who foresaw the playing field and terrain, the scope of the debate. It was Turing, however, who defined 'artificial intelligence'. By his definition, computers have already achieved consciousness. Turing had said that we may consider a machine intelligent if, in a blind test, we cannot differentiate the computer's response from that of a living, breathing person. By that standard, computers are now conscious and intelligent. IBM's 'Big Blue' defeated Chess champion Boris Spasky who charged that human beings had directed the machine. I often share that attitude with my own computer's chess program. It actually seems to learn from its mistakes.

Ada understood that the meaning of a machine is what it does. Her contribution is that this meaning may be shaped by what are now call 'programmers' who literally instruct the machine, providing it a well-planned list of discrete tasks, a program –in other words: software.

Computer technologists speak of "state". Each state is particular, analogous in some way, to a particular task that may be accomplished while in that "state." Before computers, machines may have processed information –but in a crude way. The instructions had been built-in. Consider the lever –a simple machine that nevertheless may be said to have two "states" –up or down. The meaning of either state is to be found in the work done by (or in) that state. As a general principle, the meaning of a given state is the utility it creates, the work that it does.

In Ada's wake, early computers were mere assemblages of electrically controlled "levers" called "relays." The origin of binary languages may be found in relays which are either 'on' or 'off' . Mechanical relays would be replaced by vacuum tubes and, later, by transistors. Simple circuits were called either "and-gates," or "or-gates", or, generally –'flip/flop' circuits. Even now, the largest supercomputers, reduced to their smallest components, are capable only of processing just two states: 0 and 1. But upon this basic alphabet, patterns of increasing complexity have grown exponentially. The computer has become an electronic loom in which each pattern represents a "state."

That Ada glimpsed this future almost a century and a half ago is remarkable.

Ideas That Have Helped and Ideas That Have Harmed Mankind

by Len Hart, The Existentialist Cowboy

It is said that Galileo recanted but muttered under his breath --"but it does move". Galileo had sinned against the Church. He had dared to indulge an independent opinion, a 'right' that Americans have sadly taken for granted. Whether Galileo was more fortunate than Giordano Bruno who was burned is a matter of debate. In England, Sir Thomas More was given the choice between conscience or King. More chose conscience and paid for it with his life.

Just as we moderns had grown complacent, a recent regime forced upon us an existentialist choice. Bush forever divided America. Those Americans supporting his regime are responsible for the choice they made; they are morally complicit in Bush's crimes of aggressive war and mass murder. Bush himself can and should be charged with crimes that are under US federal statutes punishable by death.

I may recant if someone has a gun to my head, but, like Galileo, I may be in danger of muttering audibly and thus defeating the purpose of muttering. At a time when the religious right either hires or creates phony 'think tanks' to promote creationist and/or 'intelligent-design' propaganda designed to pass muster with the likes of Sarah Palin, my views are entirely consistent with any religion based upon 'faith'. What the 'faithful' have forgotten is that 'faith' does not require proof or even meaningful sentences. Nevertheless, I still support the right of religious folk to espouse nonsense though, strictly speaking, a 'belief' is nonsense if logically impossible. Therefore, I believe it logically impossible to believe 'nonsense'. There is a difference between merely professing a belief and believing.

'Certitude' --the best word to describe the more militant fundamentalist churches --is inconsistent with faith. If one is 'certain' upon irrefutable proof faith, then, is not merely unnecessary but impossible. Coercion of any sort, including social pressure, is likewise incompatible with 'faith'. The word 'faith' connotes doubt. Those who are without doubt are without faith. Faith is what those who have doubts hang onto. Put another way --those who have 'faith' do not 'know' and those who 'know' have no need of faith. Faith is of all types. As a validictorian speaker at my high school put it: even the atheist has 'faith'. Some atheists have faith that there is no hell to be paid for 'denying' the 'religion' that many had tried to force upon them.

True religion by definition, cannot be militant and if militant ceases to be religion. A cult, perhaps, but not religion. There are no Christian soldiers. Conversions upon the point of a gun or sword 'don't take'! Even the fundamentalist baptist church I grew up in 'preached' that the acceptance of Christ must be chosen freely! Coercion or brainwashing is self-defeating, destroying 'souls' --not saving them. Like a bad vaccination, it doesn't 'take'. The excesses of both Protestant and Catholic faiths throughout European history are all the more tragic because neither side occupied moral high ground; all persecutions and horrific tortures were utterly baseless both logically and morally. Religion is a form of insanity in an individual and when shared among many throughout society --mass insanity. Religion has harmed humankind.

That brings up the matter of William Jennings Bryan, a self-professed 'fundamentalist Christian', who was, in many respects, a very admirable and honest person, perhaps a 'Ron Paul' of his day. But at Dayton, TN he supported efforts of the state to impose upon a curriculum a religious agenda. By definition, 'faith' cannot be imposed. Any oath imposed by law or coerced at the point of a gun or threat of excommunication is invalid. The very notion is self-contradictory. [See: Darrow, Darwin and Dayton] A more recent example is Sarah Palin who has a record trying to put 'creationists' on School Boards.

This is not a matter of faith. Certainly --for creationists, 'creationism' is not a matter of fact; they believe their theory to be fact. But 'creationism' is not subject to methodical verification as is the case with science. It is the process of verification that defines science --not the end result of either research or verification. 'Creationists' have forgotten that lesson --if they had ever learned it to beging with. Creationism is bad religion and even worse science. Both 'intelligent design' and 'creationism' are dogma --not science. Science is neither a body of knowledge nor a finite set of unchanging facts. It is, rather, a process by which meaningful statements, knowledge, sweeping theories are subject to rigorous empirical test. Both 'Intelligent Design' and 'Creationism' have harmed humankind.

The 'creationist' ideology espoused most recently by Sarah Palin is easily disproved. She believes the world is but 6,000 years old and human beings walked with or beside Dinosaurs. Simply, if we see the galaxy in Andromeda, 'creationists' are wrong! Andromeda has been proven to be some 2 million light years distant. We see Andromeda as it was 2 million years ago. If we can see it at all, 'creationism' is not only wrong, it is not science. Nor --because it is often coerced --is it faith. It harms humankind.

We can see Andromeda. In fact, I found Andromeda as a kid growing up in West Texas. I had nothing more than a good pair of binoculars that my uncle had given me and a star map. It is the only Galaxy that is visible to the naked eye. The idea that we are capable of discovering 'truth' for ourselves has helped humankind!

If we had discovered no other object, we must conclude, therefore, that the universe is at least two million years old. Of course, there are many more objects that are much, much more distant than Andromeda and they are easily discerned by the Hubble telescope, a bit more advanced than a simple pair of hand me down 7x35 binoculars duct taped to a half-assed tripod. With a bit of Trig and parallax, the distance to Andromeda can be determined even by amateur astronomers.

The 'creationist' position with regard to the teaching of 'creationism' in public schools is a straw man. Every curriculum I have ever seen teaches all science as theory. But creationism is not science and is not scientific theory. It has no place in a public school. Scientific theories are subject to proof. A religious 'creationist' would never subject any religious dogma to 'proof'. I believe that dogma has harmed humankind.

Because of the genius of our founders, people are free to act upon their religious convictions and may worship in whatever church they might prefer. But a 'religious conviction' must never be confused with a verifiable fact.

There are many things in which I have faith. But, I would hope never to make the mistake of trying to prosecute those do not share my faith. In the meantime, both of us are FREE to argue until the last red, dying sunset. It has been said that "... the Left -- from the beginnings of humankind -- has challenged us to think for ourselves, in both matters of reason and faith, while respecting those who have proven themselves advanced in studies or achievements in various fields:" I think that is our role. I respect those who profess a faith in 'good faith' but not those of 'bad faith' and its hand-maidens --dogma and superstition.

Jean-Paul Sartre and Bertolt Brecht addressed what it means to have integrity far more persuasively than any 'bible thumping' fundamentalist preacher that I had been forced, as a child, to endure. Both Sartre and Brecht addressed the issue of bad faith, essentially, the 'condition' in which an individual appropriates a false notion of self. Simply, those of 'bad faith' are not only lying to others, they are lying to themselves. Bertolt Brecht summed it up bluntly: "A man who does not know the truth is just an idiot but a man who knows the truth and calls it a lie is a crook". The photographer Richard Avedon was even more direct: "You cannot expect another man to carry your shit!"

I suspect that the GOP --as a whole --is premised upon 'bad faith', hence my antipathy. Moreover, I suspect that much of this is derived either from 'religion' espoused in 'bad faith' or GOP exploitation of religion to get votes. [Reagan and Bush Jr most prominently] To the extent that organized religion in America (especially the 'super churches' of the 'super fundamentalist evangelical movement) is but a mass manifestation of 'bad faith' the exploitation may be mutual.

One must not conclude that because of my views with regard to religion that I am immoral or amoral. I parted company with religion because I wished to be moral. Had I wanted to be immoral, I could very have remained in the church that my parents tried, in vain, to force me into. Since that time, I have shunned many another harmful cult.

Statistically, there is either no correlation between the espousal of religion and morality or none at all. Moral people may be found among atheists and agnostics. Therefore, one concludes, people do not seek religion because they wish to be moral. The histories of almost every organized religion is proof of that. Indeed, if people were inherently and naturally moral, there may have never existed a 'need' for religion.

I have been criticized for raising doubts among the faithful! I am in good company. Upon his conviction on similar charges, Socrates was forced to drink hemlock. He might have saved himself had he 're-canted' --a tactic favored by every 'establishment' including both Catholic and Protestant denominations. The tactic is a Faustian bargain in which one trades one's soul for one's life. Because he believed that "a man's soul is his self" [ the existentialist point of view ], St. Thomas More, like Socrates, refused the 'offer' that it was believed he 'could not refuse'. In Robert Bolt's great play "A Man for All Seasons", More tells his daughter, Meg: "...when a man takes an oath, Meg, he's holding his own self in his own hands. Like water and if he opens his fingers - he needn't hope to find himself again". That, I believe, is a good description of 'bad faith' as Sartre defined it. Later, when More is 'sold out' by the ambitious Richard Rich: "Why, Richard, it profits a man nothing to give his soul for the whole world... But for wales ----?"

Another great existentialist play from the period is Jean Anouilh's Becket: ou l'honneur de Dieu. As the title suggests, Becket, having first served his King with distinction, found his 'honor' in the service of "God". To act contrary to that would have been, for Becket, the supreme act of 'bad faith'.

Forced to make the existential choice, Becket chose the honor of God above his duty to his King. Simplistically, he lost his life but saved his soul. Poor Galileo! He saved only his life. I saw both movies in the same year in which I heard Stokely Carmichael address an audience at Cullen Auditorium on the University of Houston campus. It was historic --Stokely Carmichael's promise to keep alive the revolution that the assassinations of RFK and Martin Luther King Jr the following year would end. With them, the 'dream' died. Carmichael electrified the audience when he proclaimed: "I do not need a law passed by the white man to tell me that I am free! I was BORN free! I AM Free!" I am of Native American descent and likewise free! I hold this nation responsible for the genocide it perpetrated upon my ancestors. I am not subject to unjust laws of any source and most certainly not those of a regime that was illegitimate in its inception and criminal in its execution.

JFK could have made the Faustian bargain with the Bush crime family that was even then, via the Sr Bush, directing the CIA effort against Cuba. RFK threatened the same people.

Recently, a BBC documentary established that RFKs 'killers' were most certainly the CIA. Martin Luther King, of course, represented the 'black' revolution that would have rocked the establishment. King's ideas have survived him and helped humankind.

If one's soul is one's 'self', then one may never hope find it in 'organized religion', a standardized journey through preconceived dogma. By definition, every individual must take this journey and experience it. Because it differs with each individual, it cannot become scripture. The 'form' seems always the same: the 'individual, in crisis, is given a choice: his life or his soul. It is no coincidence that this 'form' becomes the structure of almost every work of literature worth reading or watching.

At the heart of a growing divide between the secular quest for knowledge and the religious conservation of dogma are two contrary views of the universe. 'Particle' and 'wave' are just words to describe a 'noumenon' --as Immanuel Kant would have called things as they just are --before names are stuck on them, things NOT as they are perceived or measured but thing in the state of mere 'being'. Kant may have referred to it as a God's eye point of view though his view of 'God' is probably not shared by American fundamentalists.

The universe itself is the logical consequence of uncertainty. A 'particle' is the 'snapshot' we make of a 'wave'. Waves, by definition, are manifested only over time --a noumenal existence in motion. Certainly --Heisenberg's 'uncertainty principles' is verbally stated thus: a 'particle's position or its velocity may be measured at any given instant but not both at the same instant.' To use the photographic analogy, a 'particle' is a 'high shutter speed snapshot' of a wave; the 'wave' itself is like a 'time exposure' --a 'wave' at longer exposures, a 'particle' at much higher speed exposures.

I like the photographic analogy. My photograph of 'something' (a noumenal existence of some sort) that makes a looping motion as it moves from 'point' A to point 'B' will look like a SOLID object if my shutter speed is slow enough. The same 'object' making the same looping motion while moving from the same point 'A' to point 'B' will look completely different if photographed at 1,1000th of a second. Depending upon how quickly the 'object' is moving, my photograph might even suggest the shape of the actual 'object'. The faster my shutter speed, the closer I get to the actual shape of an actual object but at the expense of being able to determine its speed. By measuring the 'blur' against a known 'shutter speed', I might have determined the object's speed relative to the camera. A 'looping' object may describe a 'sine wave' as it moves. For example, we think of the moon as orbiting the earth. But because the earth is itself orbiting the sun, the moon's orbit about the earth is wave-like, weaving its way to and fro as the earth proceeds in its orbit about the sun.

Some orbits may be 'frozen' sine waves. In the Neils Bohr model, an electron is said to orbit the nucleus of an atom. But as both nucleus and electron are in motion, the 'orbit' is better described as a wave. Is it particle or is it wave? It depends on how you look at it. It is both depending upon how it is 'looked at' or, to use the analogy, how it is 'photographed'. Electrons are particles if their position is pinned down, but waves otherwise. At the quantum level, particles are just smaller blurs. One wonders if anything really exists at all. To use the photographic analogy again --what shows up on the 'photograph' depends upon the shutter speed. Slow shutter speeds make blurry photographs in which a small object may appear to be large and blurry. Specifically, a moving object photographed at a slow shutter speed is 'larger' in the direction of its movement. A very fast shutter speed will result in a smaller, sharper object. Both its location and shape are determined with greater accuracy. Similarly, Heisenberg's equation describes the relationship between the accuracy of a position vis a vis a velocity.

A precise determination of velocity can only be made at the expense of a precise determination of the object's position. As a very small child, I asked my father during a car trip how fast we were going. He replied that we were going 50 mph. I asked what that meant. He explained that we would travel fifty miles over the course of an hour. Being a kid, I shot back: "But how fast are we going RIGHT NOW?" That's what Heisenberg dared to ask: how fast is that particle going right now? He concluded that you cannot know both a particle's speed and its position at the same time.

The scientist must approach the study of the universe with the naivete of a child, daring to ask questions that are free of guile and preconceived notions. It was a child, I believe, who called Kant's 'noumena' a 'God's eye' view of the world. A jaded adult might lose amid a gestalt of prejudices and pre-conceived notions a perspective so fresh and transparent.

Over the course of an hour long trip, a car is a fourth dimensional shape that has manifested over the trip's duration of one hour. That 'shape' may resemble the line that is drawn on a map. Over the duration of an infinitesimal fraction of a second --a high shutter speed snap shot --the car's 'shape' will be the one you recognize as the object that sits in your garage.
Two astronomers –Hulse (a student) and his professor Taylor were studying a radio star pair at the huge Arecibo radio observatory in Puerto Rico (it’s 305 meters across). The star pair they observed was coalescing and the energy it was loosing during this coalescence was exactly as predicted by Einstein. They received the Nobel Prize in 1993 and from then on the skepticism evaporated and all scientists believed that, due to this indirect evidence, gravitational waves did indeed exist.

--Robert M. L. Baker, Jr;.Layperson’s Description of High-Frequency Gravitational Waves or “HFGWs”Lecture given at the Science and New Technology Special Interest Group at The California Club, Los Angeles, California, USA. October 17, 2006

Raymond Chiao remembers the day, during his childhood in Shanghai, when his brother built a crystal radio set and invited him to try it. "When I put the earphones on, I heard voices," he says. "That experience had something to do with my going into physics." Chiao has since become well known for his work in quantum optics at the University of California at Berkeley. Now he is preparing an experiment that, if it works (a not insubstantial if), would be the biggest invention since radio. Chiao argues that a superconductor could transform radio waves, light or any other form of electromagnetic radiation into gravitational radiation, and vice versa, with near perfect efficiency.

Such a feat sounds as amazing as transmuting lead into gold--and about as plausible. "It is fair to say that if Ray observes something with this experiment, he will win the Nobel Prize," says superconductivity expert John M. Goodkind of the University of California at San Diego. "It is probably also fair to say that the chances of his observing something may be close to zero."

GRAVITY TRANSDUCER would reflect incoming electromagnetic radiation (green) as gravitational waves (orange). The radiation must be polarized in a so-called quadrupole pattern.

--Scientific American - May, 2002 , A Philosopher's Stone
I like the description of 'gravity waves' as ripples in the fabric of space-time. There are on the 'innertubes' some very interesting GIF animations of 'gravity waves' that have been rendered in 3-D graphics programs. These are, of course, representations in two dimensions of a fourth dimensional phenomenon. Thought of in that way, such a craft is a time machine where 'time' is the apparent motion seen in the interference patterns of two dissimilar gravity wave fronts. One gets the idea. Upon Captain Jean Luc Picard's command --engage --the Enterprise would begin a journey in 'warp drive'. If such a craft capable of exploiting the interference patterns generated by two or more dissimilar wave fronts is ever built, inter-stellar travel will allow one to surf the universe, catching a gravity wave and soaring off into space.

Teaching Darwin to Voodoo Evangelicals & Other Darwinophobes

by Omyma

If the Theory of Evolution were on sale at Wal-Mart, these would be Darwin Days. For the coincidental 200th birthday of Charles D plus the 150th birthday of the publishing of his Origin of the Species, many around the world celebrate by publishing articles, books, blogs and exhibitions on the importance of the man and his breakthrough ideas. But for some 25% of Americans, according to a CNN poll, and possibly more from the 36% undecided/don't know group, evolution is not true, not fact, not even important. Evangelicals and their conservative brethren consider it a dangerous lie.

It is not just 'evolution' but the foundations of scientific enquiry that inspires their rage. It is ironic that in this technologically-advanced nation, a large section of the population does not believe the very basis on which much of that technology, the core processes and investigations upon which much of modern civilization and advancement, is based. They are are not passive dissenters. They exert political pressure and take other actions to prevent the free dissemination of scientific ideas.

One would expect a better result in the UK, Darwin's home turf. But that's not exactly the case.
Half of British adults do not believe in evolution, with at least 22% preferring the theories of creationism or intelligent design to explain how the world came about, according to a survey.
With about 50% of Britons believing in evolution to varying degrees, this is somewhat better than the U.S., where only 39% believe in evolution (just slightly more than the undecideds), but it is far below where one would think. Even stranger is this fact:
..around 10% of people chose young Earth creationism – the belief that God created the world some time in the last 10,000 years – over evolution.
About 12% preferred intelligent design, the idea that evolution alone is not enough to explain the structures of living organisms. The remainder were unsure, often mixing evolution, intelligent design and creationism together. The survey was conducted by the polling agency ComRes on behalf of the Theos thinktank.
Why is this? Even if you take into consideration the recent hype about so-called "intelligent design", we're still left wondering what was going on in the last, say, 150 years... I was fully expecting the UK to be different, not the least because Darwin is a native son, and the whole idea should give Britons a sort of patriotic high - just in case rationality is a non-starter.

But when you consider that both the U.S. and Briton are running at roughly half for and half against, maybe we should consider something else.

Robert Haston's book The Origin of the Political Species presents the view that in fact, people are evolved to be "two tribes" or to have two political leanings - and we're talking hard-wired, in the genes. This would mean possibly roughly half of homo sapiens are liberal, and half conservative. Although it's not really that simple, the striking point here is that looking at the number of people tending to accept evolution as scientific fact vs. the number of those rejecting it outright, you get a similar rough 50-50 breakdown.

The "political species" theory goes that two opposing tendencies, genetically expressed, have evolved in our struggle for survival: the "conservative", alpha male, authoritarian, hierarchical, tradition-preserving, paternalistic, militaristic, "rule from the gut", macho, emotional (especially fear and anger), "in-group" protecting type on the one hand; and the "liberal", forward-looking, rational, empathetic, universal-thinking, peace and diplomacy-bringing, "outside-the-box" looking, artistic, egalitarian and compassionate type on the other hand.

Of course, these labels are somewhat simplistic, because everyone has a mix of each type of gene. But some people are definitely more on one side and some are definitely more on the other. Then there are the folks on the fence; the in-betweens, the people targeted in elections, the swing voters.

So what's this got to do with evangelicals and their intrusion of religion into politics? Religion, especially and particularly evangelical Christianity, which involves voodoo-like trances, speaking in tongues, and other obvious examples of irrationality, is a hotbed of conservatism. It gives their world view, their "tribe", a double-whammy: it appeals to the emotions and creates a bonded "in-group", and simultaneously numbs the sensibilities of those people to rational, progressive governance, thus paving the way for typical conservative top-down, hierarchical, paternalistic government. And so atheist Karl Rove harnessed the power of evangelical Christianity to numb millions of rural, relatively uneducated, unempowered people into rallying behind their own subjugation to the Bush regime's heavy-handed, militaristic, undemocratic, authoritarian-style government.

President Obama's rise to power is not only a direct blow to conservatism, but shows that conservatism has completely lost its bearings, having nothing but "gut-instinct" to go on and a set of irrational, but strongly felt, slogans, usually starting with the instinctive expression, "NO!" and "We gotta win!" So you have the scenario of all Republicans still standing lining up and crying "No!", with the "reasoning" being repetition of platitudes about tax-cutting that their own gurus have been shamed into admitting were all wrong. The only "yes"-sayers were women: who often have a certain ability to think progressively, when pushed to the wall. But the problem is the basic conservative mind-set is not going to change.

And if it's not going to change, does this mean that half the population will be literally fighting progress, keeping people in the dark ages, working hard to send humanity farther and farther back in time until we end up with the victory of the "earth is at rest" theory? No, because many conservatives actually already believe in the theory evolution and would support it vigorously if they really knew what it was. But it's been presented to them as a "progressive" and "anti-God" idea, and the fear factor, self-defense thing kicked in. Progressives have also focused the narrative on God vs. evolution, which is patently absurd, instead of on common ground, such as how this "theory" has helped humanity survive. And anything less than common ground is totally useless, impractical, and hence, not all that progressive.

Regardless if one believes liberal and conservative tendencies are in the genes, history does display conflict between them fairly dramatically. Or, as Mr. Haston put it:
Given that the world‘s climate has seesawed back and forth, the engine of evolution has learned to keep plenty of older genes in circulation, ready to be selected when the pendulum swings back and forth. Man‘s culture has done the same, swinging from Dark Age to Renaissance and back with far more fury and speed than the climate. So keeping a balance of traits in play is a good survival strategy. ...

Stop trying to change each other because you won‘t. Take the advice of Sun Tzu: understand yourself and your enemy and win every battle. To be as blunt as possible: Understand the view of those who don‘t agree with you and why they have it, or you are screwed. If your opponent learns to and you refuse to, then you are only screwing yourself.
To scientists, Darwin's theory and the science it generated, which has since morphed considerably (i.e., evolved), is an essential part of the scientific and technological gains which have benefited society and also hold some of the keys to solving projected future problems. In a democratic society, which is essentially a progressive or "liberal" thing, it is almost suicidal to mix religion with science, but that fact has to be presented to conservative minds in a different way that takes their basic mindset into account.

In other words, progressives have been shooting themselves in the foot on this issue by such in-your-face non-starter attitudes as Christopher Hitchens, for example, or Richard Dawkins, who are almost evangelical about atheism. It isn't Christianity per se, or Voodooism per se, that threatens science. It's the politicization of religion. So to get them to back off, we should take a 2-pronged approach, one "liberal" in style and the other "conservative".

For the "liberal" style, present the universal benefits and plusses of evolution, as contrasted to the total disaster that would occur if we were to turn back the progress of free inquiry and impose some sort of religious-based "science". We could start with antibiotics. It's a known fact that bacteria become resistant. They evolve. They become different species. It's just the time-frame is faster, hence more easily understood. Without evolutionary theory, we couldn't have modern medicine or understand why antibiotics started to fail after they were initially successful. Shall we then impose a ban on all medical research, except that which is mentioned specifically in the Bible? Few conservatives would agree to that. Then remind them of the geocentric universe. Shall we cancel those satellites and cell phones and that Devil Internet? I doubt many would follow this route.

In fact, those who would follow this route might consider attending a certain university in Peshawar, Pakistan, where they might find some folks of a similar mindset. Would those evangelicals really like their newfound cameraderie with the Taliban, for example?

For the "conservative" style, bring a religiously respected Wise Man to confer his judgement in a time-honored manner on this issue. To wit, Solomon.

What would Solomon have suggested? Voila:

If you want to impose religious dogma on science, then we must equally impose scientific knowledge and opinion on religion. No sermon, no priest, no pastor, should be allowed to operate without presenting the views of Darwin and others on Natural Selection and Evolution. And while we're at it, the Pope should have Darwin's Origin of the Species on his required reading list. Not only that, they have to give prime-time lectures on the subject - equal time for "equal" views. And, to be even more "fair", we should give equal time to the theory that "the sun revolves around the earth on the ether, or firmament", not to mention the notion that the earth is carried on the back of a giant turtle. Whenever priests read sacred texts, they should supplement those texts with "balancing" readings from scientific literature. If religion is "relevant" to science, then science is equally "relevant" to religion.

Oh, does this strike some young-earthlings as infringing on their freedom of religion? We likewise detest infringement on freedom of scientific inquiry by enforcing totally unrelated concepts, sources, and mythologies on it. If they like their earth young, their dinosaurs recent, and their biological change instantaneous, that's fine for them. But if they want to impose it on the rest of us, we demand the right to impose scientific facts on them. Otherwise, they can enjoy living as their ancestors did when the earth was indeed younger - with stone tools.

And by the way, if God wanted creation instantaneously, magician style - to our human perception, no less - then wouldn't He have created Instant Gestation? Or Instant budding, flowering, and fruition in plants? Why all the mess, the time, the stages? Would these hot-n-heavy evangelicals miss that flowering stage? Or that season for fruit? Did anybody ever read Ecclesiastes? Obviously, all "creation" occurs in stages, in gradual progression, from the birth and death of stars to the birth and death of living creatures, to the birth and death of life itself (as in, say, extinctions). Beyond that, arguing about God is totally useless scientifically.

As for the Darwinophobes, their idiocy has been laid bare. Nobody wants to give up their cell phones in order to have Flat Earth Theory resurrected, except a few crazies. Nobody wants to give up the benefits civilization has attained by scientific discoveries and applications based on Darwin's theory. Meanwhile, scientists and progressives should lay off the pro-atheism, often condescending heavy-hitting when presenting evolution. After all, it just means "gradual change". That happens in the womb before every baby is born. Nobody can argue against that.

The soft-sell worked on Dalai Lama, who looked at Darwin's Expression of the Emotions in Man and Animals, discovered his abolutionist and compassionate views on humankind, and was won over.
...the father of evolution theorised that emotion and compassion were universal and naturally selected features of humans...

"I am now calling myself a Darwininian," Ekman recalled the Dalai Lama saying, after Ekman read him some passages of Darwin's work.
Meanwhile, when feeling frustrated over Voodoo science and general ignorance created by ultra-conservative mindsets and policies, think about the possibility that this whole controversy may be part of an ongoing evolutionary process that even affects our politics. The best civilizations are those that take the best from both sides, and in this sense Obama stands out as a potentially great leader, balancing as he does without capitulating to a conservative brand that no longer adequately supports even its own constituent conservatives - as Bush has presided over arguably the most profligate government in U.S. history. "Profligate" is not a conservative value. Just as condescension and a confrontational, dogmatic approach to scientific argument is not a liberal one.

Carl Sagan: Pale Blue Dot

By Len Hart, The Existentialist Cowboy

Carl Sagan left us a precious legacy. The Cosmos. And also a poignant reminder of the fragility of our own "pale blue dot", the fleeting ephemeral nature of all that is beautiful and worthwhile.

When Carl, if I may be so familiar, warned us about greenhouse effects and global warming, we listened. And not just because the beautiful Pachelbel's canon in D major played so persistently beautiful in the soundtrack. Sagan illuminated our world all too briefly and briefer still when measured against the cosmological eons about which he spoke so movingly.

We could do far worse than "getting caught up" in his vision. In retrospect, it seems mundane to say that he made of science an adventure. Rather, he made of evolution a symphony, of astronomy a sonnet. With his signature phrase "billions and billions", Sagan evoked for me my own childhood amid the vast expanses of West Texas where one could look up into a velvety black sky far from city lights where "God" had flung "billions and billions" of sparkling diamonds.

It is because the air is so crystal clear and so far removed from city lights that UT's famous McDonald Observatiory (pictured above) is located in the Davis Mountains near Fort Davis, just north of Big Bend. The Milky Way, our own spiral galaxy, is not cloud-like at night. It is as if Carl Sagan's "billions and billions" of stars could be seen individually in one panoramic sweep from Guadeloupe Peak to Santa Helena. It is no cliche that the stars at night are big and bright deep in the heart of Texas. Science was no longer study, it was the merging of one's own life and being with a cosmos vaster than could be imagined. That is my childhood recollection of our own cosmos. It is also Carl's legacy.

Watch and enjoy.

Carl Sagan: Pale Blue Dot

Carl Sagan's phrase "Pale Blue Dot" is now a part of the language. Not just a handy description of a tiny planet in a vast cosmos, it has changed the way we think about our precious and fragile vessel - Earth.


Obviously, Ted Turner's questions were posed before George W. Bush would attack and invade Iraq, perhaps destablizing a volatile Middle East in the process. Sagan referenced Mikhail Gorbachev. Surely it is remembered that it was Gorbachev who put total nuclear disarmament on the table at Reykjavik. It was Ronald Reagan who blinked. It is the Ronald Reagan legacy that George W. Bush keeps alive at our peril. Clearly, the most powerful people on earth had not listened to Sagan. And they are not listening now.

The following excerpts are Carl at his best - debunking superstition even as he celebrates the precious fragility of the home planet.
That's here, that's home, that's us. On it, everyone you love, everyone you know, everyone you ever heard of, every human being who ever was lived out their lives ... lived there on a node of dust suspended in a sunbeam.

A New Dark Age

by Len Hart, The Existentialist Cowboy

The Enlightenment dims and sober writers bemoan a new, incipient dark age. Who will "rage against the dying of the light"? Fallacious attacks on Darwinism, indeed, science itself, threaten to spread beyond the confines of radical, fundamentalist America to strike deep in the heart of the enlightenment itself: Europe, France, and even Turkey.

At issue: a theological concept masked as "science". It is most often called "Intelligent design". By any name it is a trojan horse, theology dressed up like science, the intellectual equivalent of bird flu, contagious, virulent, just as deadly to rational thought. Intelligent design must be exposed for what it is: psuedo-science: 15 Answers to Creationist Nonsense.
Embarrassingly, in the 21st century, in the most scientifically advanced nation the world has ever known, creationists can still persuade politicians, judges and ordinary citizens that evolution is a flawed, poorly supported fantasy. They lobby for creationist ideas such as "intelligent design" to be taught as alternatives to evolution in science classrooms. As this article goes to press, the Ohio Board of Education is debating whether to mandate such a change. Some anti-evolutionists, such as Philip E. Johnson, a law professor at the University of California at Berkeley and author of Darwin on Trial, admit that they intend for intelligent-design theory to serve as a "wedge" for reopening science classrooms to discussions of God.

Scientific American
The exhibition on evolution at the magnificent new science department at the Museum of Natural History in New York is countered by a proliferation of Creationist Museums around the country (US). A new production of Inherit the Wind may not reach an audience large enough to any good i.e., to educate Americans about a domestic, ideological danger.

Columbia University professor Philip Kitcher strikes back with Living with Darwin. Kitcher's position is not that ID ("Intelligent Design") isn't science but that it is "dead science", consisting of propositions long ago discredited, some by Darwin himself. Darwin is, of course, ignored and attacked by demagogic politicians, the religious right and various sycophantic politicians. Darwin's arguments against ID are still valid, merely ignored by the religious right.

Kitcher would strike an uncomfortable truce astride an increasingly fanatic right wing on the one hand and genuine science on the other. Kitcher would hope this possible, even necessary, if science is to survive at all. Is such an unholy truce possible? Can real science live in a world in which experiment is replaced by referendum, where propaganda impersonates evidence?

The scientific community resolved the issue long ago; Darwin himself refuted ID with a mountain of verifiable evidence. That those issues are raised now among religious demagogues and politicians raises disturbing questions about the quality of scientific education. Has it failed entirely? Have zealots succeeded in isolating science? Is it the aim of "religion" to destroy the spirit of free enquiry? Will science itself be subject to laws by which an 'orthodoxy' is decreed under the rubric of 'democracy'? Will a latter-day 'Galileo' be forced to recant?

Among the concepts most difficult for the theologically inclined is the idea that the random bonding of nucleotides in a primordial soup might have triggered the evolution of life on earth, indeed, in the universe. Fundamentalists find it inconceivable that complex molecules might spring up by chance. As Scientific American points out, evolution does not depend on chance alone to create organisms.
As an analogy, consider the 13-letter sequence "TOBEORNOTTOBE." Those hypothetical million monkeys, each pecking out one phrase a second, could take as long as 78,800 years to find it among the 2613 sequences of that length. But in the 1980s Richard Hardison of Glendale College wrote a computer program that generated phrases randomly while preserving the positions of individual letters that happened to be correctly placed (in effect, selecting for phrases more like Hamlet's). On average, the program re-created the phrase in just 336 iterations, less than 90 seconds. Even more amazing, it could reconstruct Shakespeare's entire play in just four and a half days.
Scientific American
Evidence for evolution is with us everyday, in the stars at night, wheat, fruit flies, giraffes in the wild, and, most colorfully according to Carl Sagan, the Heikegani Crab.

However, if it is the fact of evolution that fundamentalists seek, they have only to look up at the stars at night. The vast distances to many of those stars have been established beyond all reasonable doubt. The farthest quasars are nearly fourteen billion light years away. It has taken, therefore, nearly fourteen billion years for that light to reach earth.

Many creationists discount evolution because the age of their universe is predicated on Bishop Usher's estimate that the universe is only some 6,000 years old, a number computed by adding up the age of the prophets and other time events described in the Bible and adding those years since that time. However, 6,000 years is not nearly long enough for the light from even closer stars to have reached this earth. Yet those stars exist, we see them, and their distances can be demonstrated. Their existence is evidence of both the size and the almost unfathomable age of the universe.

There are those who will tell you that the fact of evolution is so obvious that it is a tautology: what survives, survives. Evolution may be summed up thus: those members of specie who survive long enough to procreate will pass its genes on to a succeeding generation; those members who do not, won't. Hence the tautology. One of the most lucid explanations of the evolutionary process was written by Julian Huxley, Evolution in Action. It is still available.

Similarly, scientists studying the causes of aging have observed the fact of evolution in Fruit Flies whose life cycle is about one day. They are borne; they mate; they die. There isn't much time to do anything else. New variations are observed in Fruit Flies in very short periods of time.

Even folk wisdom recognizes the validity of evolution. Cowboys and farmers alike often said: never kill a slow roach. You just improve the breed. That is a good description of the process of "selection".

How many "creationists" have bothered to talk to a farmer. Any farmer who has ever bred for specific characteristics can bear witness to the fact of evolution as it is understood today. Naturally, when I think of Kansas, I think of both The Wizard of Oz and wheat. Wheat does not grow in the wild, yet its origins are most certainly ancient wild grasses. One suspects that wheat benefited largely by what evolutionists would call artificial selection, a process in which natural selection is helped out, possibly by a farmer who knows how to breed or, in evolutionary terms, select, for specific characteristics.

I fear for future generations that may be victimized by a fanatic Christian "right".
We keep trying to explain away American fundamentalism. Those of us not engaged personally or emotionally in the biggest political and cultural movement of our times—those on the sidelines of history—keep trying to come up with theories with which to discredit the evident allure of this punishing yet oddly comforting idea of a deity, this strange god. His invisible hand is everywhere, say His citizen-theologians, caressing and fixing every outcome: Little League games, job searches, test scores, the spread of sexually transmitted diseases, the success or failure of terrorist attacks (also known as “signs”), victory or defeat in battle, at the ballot box, in bed. Those unable to feel His soothing touch at moments such as these snort at the notion of a god with the patience or the prurience to monitor every tick and twitch of desire, a supreme being able to make a lion and a lamb cuddle but unable to abide two men kissing. A divine love that speaks through hurricanes. Who would worship such a god? His followers must be dupes, or saps, or fools, their faith illiterate, insane, or misinformed, their strength fleeting, hollow, an aberration. A burp in American history. An unpleasant odor that will pass.

Harpers, Through a glass, darkly: How the Christian right is reimagining U.S. history
It is important that science be taught in school. Evolution was made clear to me in my junior high school science class. The topic was Giraffes which eat the leaves of trees in their habitat. Lamarck, we were taught, believed in acquired characteristics. In Lamarckian terms, the Giraffe had a long neck so that he could reach the leaves. The Darwinian view turns that on its head i.e, those Giraffes able to reach the higher leaves would pass their genes on to another generation of longer necked Giraffes. The short neck Giraffe would most certainly die before he could mate. Put yet another way, the long necked Giraffe survived and procreated because it had a long neck; it is inaccurate to say that it had a long neck so that it would survive.

I have long considered the words "so that" to be red flags, signaling a question to be begged, a perversion of logic. The words so that almost invariably signal a thought process that works backward from end results. Human beings, having evolved brains, are capable of doing precisely that.

Interestingly, Earnst Haeckel did not share Darwin's enthusiasm for natural selection as I have stated it in simple terms here. Haeckel, in his own version of Lamarckism, believed that biological diversity could be attributed to an environment acting directly on organisms to produce new species, new races.

There are crabs in Japanese waters that bear a "human face". They are the Heikegani crab, native to Japan. The carapace resembles a human face, or - with some imagination - a Samurai warrior. Legend has it that they are the re-incarnation of ancient Samarais, Heike warriors who died at the Battle of Dan-no-ura. (See: "The Tale of the Heike") Indeed, patterns on the carapace bear a striking resemblance to a human face. It is technically inaccurate, however to say that the ridges "...serve a very functional purpose as sites of muscle attachment". This is akin to saying that Giraffes have long necks so that they can eat the leaves off the taller trees. More accurately, similar patterns are found on species in many parts of the world, including fossilized remains. The patterns survive as the crabs themselves survive to pass on their genes.

Carl Sagan had a more colorful tale to tell. In his popular science television show Cosmos: A Personal Voyage, he linked the patterns to the local legend of the Heiki warriors. Sagan cited the crab as an example --not of natural but of unintentional artificial selection. Sagan told the story of local fishermen throwing back those crabs whose shells resemble the ancient Samurai. Those not resembling Samurai were eaten. Those thrown back survived to pass on their genes.

Living beings themselves may be thought of as "living fossils". We carry in our genes a code that isthe result of billions of years of "code writing". Our own fetal development seems to mirror that process. According to Ernst Haeckel (1834-1919): "The ontogeny recapitulates phylogeny."

It is interesting that Intelligent Design is often espoused by the same political mindset that embraces "Social Darwinism". Both are equally bogus. Both are embraced by the right wing though they are incompatible theories. It is odd to find even fallacious perversions of Darwin espoused by a group that is defined by its hatred of all things Darwin. It is equally odd to find Intelligent Design, however fallacious, espoused by Social Darwinists. The obvious conclusion is that these people just haven't given even their own ideologies, let alone Darwin, enough thought.

Social Darwinism does not follow from "Darwinism". Worse, it attributes to Darwin positions he never took. The term "survival of the fittest" was never used by Darwin but has been variously attributed. Hofstadter seems to attribute that phrase to rail road men:
Railroad executive Chauncy Depew asserted that the guests of the great dinners and public banquets of New York City represented the survival of the fittest of all who came in search of fortune. They were the ones with superior abilities. Likewise railroad magnate James J. Hill defended the railroad companies by saying their fortunes were determined according to the law of survival of the fittest.

—Hofstadter, Richard; 1959; Social Darwinism in American Thought, Braziller; New York.
Elsewhere, the term is attributed to Herbert Spencer who clearly inspired a generation of radicalized, latter-day robber barons and, bluntly, few of them evince the "...quality of mercy" so immortalized with but a few words by Shakespeare:
[Herbert] Spencer said that diseases "are among the penalties Nature has attached to ignorance and imbecility, and should not, therefore, be tampered with." He even faulted private organizations like the National Society for the Prevention of Cruelty to Children because they encouraged legislation.

Social Darwinism and American Laissez-faire Capitalism
An equally fallacious corollary to "Social Darwinism" is often phrased this way: the rich are rich because they are better, work harder and are more intelligent. George W. Bush put it more crudely: “The poor are poor because they are lazy!” In the same vein, the conservative economist Joseph A. Schumpeter likened recessions to a "douche" leaving us to wonder just who is "douched" and how? More importantly: who gets to make those life and death decisions? It is difficult not to conclude that New Orleans after Katrina is but the disastrous consequence of this kind of "blame the victim" thinking.

It is not surprising, then, that Spencer's influence continues, not in the field of biology, but in economics, specifically those theories most often associated with the right wing: the American apologists, William Graham Sumner and Simon Nelson Patten.

Spencer, believed that because society was evolving, government intervention ought to be minimized. Nevermind that government is but a function of society and responsible to it. It is because of the lasting Influenc of Spencer that the idea of the “rational man” making rational decisions in a free market is still in use. In practice, however, economic decisions may or may not be rational.

servative work mightily to force reality into a conservative, theoretical mold but that's bad science. Models must describe reality —not the other way round. John Nash, recently the subject of the motion picture, A Beautiful Mind, argued persuasively that not only games but societies and economies benefit more from cooperation and community than from competition.

While Bertrand Russell's work in the Principia Mathematica sought to ground mathematics upon a foundation of pure logic, it was optimistically thought that it would then be possible to construct a "Universal Truth Machine" - a "computer", if you will, that would produce all true theorems from any given set of axioms. A "formal system". Some twenty years later, Gödel's famous Incompleteness Theorems "proved" that no such machine is possible. There is always at least one true theorem that such a machine is incapable of writing - no matter how well it is programmed, no matter how well phrased the axioms.

The significance of Gödel's theorems is this: even as we near a phase in quantum physics when it appears that we may be able to write an equation which will amount to TOE, a Theory of Everything, we will come up short. No such theory is possible. Sir James Jeans once wrote that we may never be able to open the back of the watch and describe its workings; likewise, as human beings striving to understand a universe of which we are a part, we may never be able to see the face of God and describe it. We become ourselves a part of an infinite regress.

But - we must be free to believe that the face exists and free to believe that it doesn't. We must be free to find the truth for ourselves. As Socrates put it: the unexamined life is not worth living. Our choices define who we are as individuals, and collectively, as a species. Religious ideology denies us the freedom to make that defining choice freely. Bertolt Brecht said "A man who does not know the truth is just an idiot but a man who knows the truth and calls it a lie is a crook." Religious ideology parading as science is a crook.

"We have to touch people..."

by Len Hart, The Existentialist Cowboy

In my last article, I referred to Jacob Bronowski, whose Science and Human Values addressed not merely the objective, scientific bias behind "logical positivism" but also the human drive to create in both science and art. Arguably, this drive is as basic as are the instincts to procreate, eat and seek shelter.

Bronowski, was a scientist, a positivist; but, just as importantly, he was a humanist. When Bertrand Russell would wander into the arid deserts of pure symbolic logic and linguistic abstraction, Bronowski, would bring us all back to earth with the human touch, a comforting reminder that "'...science is not a mechanism but a human progress."

I cannot believe that it was by accident that what may be his finest effort -- Science and Human Values --was written in the war scarred, arid intellectual landscape that was the post World War II world. The surreal devastation that had been Hiroshima and Nagasaki were symbolic of that world. It was a world that dared to ask or was perhaps forced to confront the frightening question: what would I do if I were the only human being to survive a world wide apocalypse, the last human being left alive?

Positivism is associated with Comte but more recently with the "logical positivists" like A.J. Ayer who proposed and outlined in Language, Truth and Logic a "verifiability criterion of meaning":
"A complete philosophical elucidation of any language would consist, first, in enumerating the types of sentence that were significant in that language, and then in displaying the relations of equivalence that held between sentences of various types.
For Ayer, the function of a sentence is to convey meaningful information. But, if only meaningful sentences are significant and nonsense insignificant, then what is the meaning of meaning? Whether Ayer successfully offers up a meaning of meaning, as he had hoped to do, becomes the litmus test of his legacy. Did he succeed? Or --was Wittgenstein correct to state that all such "positivist" attempts end in infinite regress. What is the meaning of the meaning of meaning?

For Ayer, meaningful sentences are significant because they are verifiable or because they are tautologies. For example, "bald men have no hair" is true by definition. "Synthetic sentences", as Ayer classified them, are only true when measured empirically but are significant because they may be so verified. Statements about the height of certain mountains, on earth or moon, are resolved only by actually measuring the mountain. But statements about them, even if false, are nonetheless, significant. For the moment, we may assume reasonably accurate methods of measure.

Ayer is dry reading:
2. Reduction of material object language to language about sense-contents.

logical constructions (p. 63): if we can provide a definition in use showing how to get rid of a term ‘a’ in favor of other terms ‘b’, ‘c’, etc., then we may say that the thing supposedly referred to by ‘a’ is a logical construction out of the things referred to by ‘b’, ‘c’, etc. So, for example, tables are logical constructions out of sense-contents. (Here is the tendency for positivism to lead to idealism!)
--Language, Truth and Logic, A. J. Ayer
Bronowski, by contrast, talks as much about creation as verification, about culture and civilization as about symbols and formal systems:
This is the act of creation, in which an original thought is born, and it is the same act in original science and original art. But it is not therefore the monopoly of the man who wrote the poem or who made the discovery. On the contrary, I believe this view of the creative act to be right because it alone gives a meaning to the act of appreciation.

...

'The society of scientists is simple because it has a directing purpose: to explore the truth. Nevertheless, it has to solve the problem of every society, which is to find a compromise between man and men. It must encourage the single scientist to be independent, and the body of scientists to be tolerant. From these basic conditions, which form the prime values, there follows step by step a range of values: dissent, freedom of thought and speech, justice, honour, human dignity and self-respect.'
Only Bronowski, who understood science as well as art, could have written this perfect synthesis of both sides of the human brain, this perfect description of the cultural role that is often played by science.

The act of fusion is the creative act, he wrote. Few have written as eloquently or as precisely about the creative process. Indeed, few have known or understood that both science and art are products of the same human will to create. The artist will produce a gestalt of his/her own brain and hand. The scientist will reconcile, for example, Everest as seen from the north with Everest as seen from the south.
All science is the search for unity in hidden likenesses. Let me illustrate. Western mountain climbers, at home with compass and map projection, can match a view of an some inaccessible and rarely seen mountain with another view that they have seen years ago. But to the native climbers with them, each face is a separate picture and puzzle. The natives may know another face of the mountain, and this face too, better than the strangers; and yet they have no way of fitting the two faces together.
...

On the morning of the 27th we turned into the Lobujya Khola, the valley which contains the Khombu Glacier (which flows from the south and south-west side of Everest). As we climbed into the valley we saw at its head the line of the main watershed. I recognized immediately the peaks and saddles so familiar to us from the Rongbuk (the north) side: Pumori, Lingtren, the Lho La, the North Peak and the west shoulder of Everest. It is curious that Angtarkay, who knew these features as well as I did from the other side and had spent many years of his boyhood grazing yaks in this valley, had never recognized them as the same; nor did he do so now

The leading Sherpa knew the features of Everest from the north as well as Shipton did. And unlike Shipton, he also knew them from the south, for he spent years in this valley. Yet he had never put the two together in his head. It is the inquisitive stranger who points out the mountains which flank Everest. The Sherpa then recognizes the shape of a peak here and of another there. The parts begin to fit together; the puzzled man's mind begins to build a map; and suddenly the pieces are snug, the map will turn around, and the two faces of the mountain are both Everest. Other expeditions in other places have told of the delight of the native climbers at such a recognition.

It was a flash of pure creative inspiration that lead Newton to conclude that the moon is falling, literally, around the earth, that an orbit is simply an acceleration of a falling body graphed over time. It was Einstein who took this creative "unification" yet another step. This acceleration graphed over time is a "projection", the very curvature of space-time itself.

It was Bronowski, who urged that we be not "...overwhelmed by the scale of science." There is still work to do. The discovery of mesons occurred during attempts to reconcile our understanding of light as "wave" with its behavior as "particle". Likewise, it is hoped that "string theory" or some other TOE (theory of everything) will make of science an ultimate creative fusion.

For Bronowski, the appreciation of art as well as the understanding of science lies in the willingness of a third party, an observer, to re-create the process. To do so is to share the creative process itself.
The poem or the discovery exists in two moments of vision: the moment of appreciation as much as that of creation; for the appreciator must see the movement, wake to the echo which was started in the creation of the work.'
There are difficulties with both Bronowski and Ayer. Ayer, a thorough-going, formidable logician, cannot verify value statements nor can he state the conditions under which such statements might be verified. His own "Verifiability Criterion of Meaning", his meaning of meaning itself, prevents his doing so.

Bronowski, significantly does not reject such positivism. He embraces its contradiction and transcends it in another paradigm. He humanizes it, pointing out in a single sentence, the underlying, unproved social injunction implied in Ayer's analytical methods. That implied imperative is:
We OUGHT to act in such a way that what IS true can be verified to be so.
It was, after all, Ayer and his fellows, who had eschewed the very word "ought". Thus, at a time when modern philosophy had consigned human values to the realm of meaninglessness, Bronowski, conjoined them in a supreme act of creativity.

Bronowski is best known for his monumental The Ascent of Man, a series that he wrote and hosted for the BBC. In thirteen episodes, Bronowski traced the evolution of human society. Many characterize this monumental achievement as refuting Kenneth Clark's earlier Civilization series. That criticism misunderstands both Bronowski and Clark. I like to think of both efforts as book ends on a single shelf. The Wikipedia assertion that "...the two series can be seen as a dialogue between two fundamentally opposed philosophies" misunderstands the nature of both perspectives as the Sherpa, described by Bronouski in Science and Human Values, failed to recognize Everest from the other side.

Bronowski is not easily reduced to one thing or the other. A thorough-going scientist, he was as much a humanist. As a perpetual war is waged in Iraq and the specter of international "terrorism" is raised by demogogues and genuine terrorists alike, we are in need of real humanists. We are in need of more Bronowskis. We are in need of a rational, yet creative and meaningful, world.

The most moving moment in the Ascent of Man occured in an episode entitled: 'Knowledge or Certainty'. In it, Bronowski visited Auschwitz where many members of his family had died.
We have to cure ourselves of the itch for absolute knowledge and power. We have to close the distance between the push-button order and the human act.

We have to touch people.
Addendum:

Since posting this article, I found another take on Bronowski and Clark. It is from the nationally syndicated Engines of Our Ingenuity hosted by Dr. John Lienhard of The University of Houston's College of Engineering. Lienhard had prepared a broadcast about both Clark and Bronowski for "Engines". Here is an excerpt and a link to a transcript of the broadcast.
Watch either of these TV series by itself and I promise you'll be enchanted. But watch both, and you'll see a stunning convergence from two directions. Clark and Bronowski converge on hope, they converge on belief, they converge on the pervasive unity of the human species. Of course both are wary. In the end, Bronowski says,
We are all afraid ... That is the nature of the human imagination. Yet [we have] gone forward. ...
And a worried Kenneth Clark, facing the social upheaval of the late '60s, says (as much to himself as to us),
... civilisation has been a series of rebirths. Surely this should give us confidence in ourselves.
They both clearly assert our capacity for saving ourselves. They realize that technology, science, and the other arts have always converged upon our problems. And they surely remain our only real hope in troubled times.

When Ascent of Man aired, some "critics" suggested that Bronowski aimed to refute Clark. I never saw it that way. Indeed, Lienhard referred to a "convergence":
