Shame
Stars hide your fires! / Let not light see my black and cheap desires!Several films, Shortbus and 9 Songs to name two, have sought to ‘de-eroticize’ explicit sexual scenes and depict them as some kind of a happenstance in the broader context of the plot. (More specifically, what I am referring to here is un-simulated sex in mainstream cinema and not just a sleazy B-grade flick meant to titillate). Unfortunately, however, I have often found films like these to be lacking a sound storyline in the first place. As a result, ironically, such misplaced noble intentions have only served the purpose of turning them into some glorified form of soft pornography. Truth be told, I have seen porn movies with a better tale to tell. Therefore, it was a welcome respite when I read some rave reviews about Shame.
One of the few movies I have come across that struggle to deal with the theme of sexual addiction, Shame is unapologetic about its graphic, and almost always unromantic, portrayal of the sexual act. Often nightmarish, it can be best described as a story about neurosis and dysfunction. The protagonist, Brandon, leads a secluded private life in New York and can’t seem to stop thinking of women. Or fucking them, for that matter. He indulges this strange addiction because he must, not because he enjoys doing so. Contrary to expectations, he still hasn’t come to accept it and his innate sense of guilt continues to torment him. His self-loathing manifests itself in his distance from people, even his own sister. As if afraid to be known, he is cold towards his co-workers, prostitutes, and strangers. His fanatic obsession is slowly depriving him of any recognizable human impulses and making him incapable of ordinary human contact. It’s quite obvious why he wants no witnesses to his fall from grace. He loves no one and wants no one to love him.
“We’re not bad people. We just come from a bad place.”The ‘status quo’ is disturbed when “Sissy”, a neurotic, albeit carefree, aspiring cabaret singer comes to stay with her brother for a few days. As her presence brings Brandon’s darkest desires under close scrutiny, his rage against his own shortcomings surfaces in various forms. In a terse scene, desperate to grant some semblance of normalcy to his life, he dumps his stash of pornography, including his computer, in the garbage bin. Sissy is a witness to these trials and despite needing her brother more than he needs her, tries her best to comfort him. But Brandon is in a world of his own, more afraid than ignorant of her advances. It is suggested that a shared experience in their common past somehow damaged the two siblings. But, as might be appropriate, we never get to find out the hows and the whys.
I have often wondered if dysfunction in the private and emotional lives of such people translates into some kind of a morbid fascination with order and functionality in their public and professional lives. For instance, Brandon lives in an apartment that can only be described as sterile and excels at his work. He is zealous about cleanliness, ferociously cleaning the germs from the lavatory seat with toilet paper, before using the stall to masturbate. Perhaps, he has none of the distractions that trouble the ordinary family man. Aren’t serial killers supposed to be extremely methodical and scrupulous as well?
The title of the film might comes across as intriguing as Brandon finds himself succumbing to self-pity and disgust more often than shame. His is a story not so much about Crime and Punishment as it is about Addiction and Humiliation. But there is a close-up of his face towards the end that, in my opinion, captures the essence of his most private emotion. At a cheap hotel, he is having sex with two women. At the same time. But there is no concern with the movements of his lower body. Or his partners, for that matter. The close-up restricts our view to his misery. As he is about to have an orgasm, instead of pleasure or relief, there is pain and suffering writ large over his face. This is the burden that he must carry everyday. His cross to bear. The shape of his shame.

Roads to Reality: We’ve got a Problem.
Noted astrophysicist, cosmologist, and popular science author, Carl Sagan ends his book The Dragons of Eden with the following lines: “The universe is elegant and intricate. We wrest secrets from nature by the most unlikely routes”. Even though the subject matter of the book deals with his speculations on the evolution of human intelligence, this series of articles, should it manage to succeed in its aim, should serve the purpose of highlighting the veracity of his words. The fabric of the cosmos does present the human intellect with numerous challenges. As we unravel its umpteen layers, the excitement of having solved a mystery can be said to only marginally exceed the frustration at encountering new questions. In this mythical quest for secrets, as hope trumps disappointment, the cycle of discovery keeps reinventing itself as one puzzle replaces the next.
In my last piece, I had tried to illustrate how the element of uncertainty is embedded in the very fabric of quantum mechanics (QM). It is not of the kind we encounter in classical mechanics, where trusted laws can help us determine with absolute certainty which way a tossed coin will land. Uncertainty in QM refuses to reveal its secrets beyond a certain ‘probability wave’, or more precisely wavefunction , that predicts the likelihood of the occurrence of an event. It is only when we interact with the system, with the intention of measuring some of its property, that this haze of multiple possibilities clears and assumes a definite outcome.
Mathematically, this evolution can be said to have two distinct stages. In the first stage, the probability wave of an electron (or some other fundamental particle) evolves over time – smoothly and gradually – according to Schrödinger’s equation. The second stage is when we make contact with the observable reality, causing the electron to snap to, let’s say, a particular position, thereby ‘collapsing’ the wavefunction. And therein lies the heart of our ‘problem’.
The quantum mechanical description of reality is clueless about this collapse. According to Schrödinger’s equation, wavefunctions do not collapse. It is simply a convenient add-on that helps theory agree with observations (I have come to believe physicists often do that). Since the cat is never observed to be both dead and alive, the explanation safely posits that the act of measurement causes the wavefunction to relinquish its state of quantum limbo and usher one of the possibilities into reality. But what is so special about the act of observation that causes this choice to be made? How are the different possibilities converted onto an actual, sharply-defined outcome? This dilemma is what’s known as the Quantum Measurement Problem and forms the core of several contending interpretations of QM that seek to explain what has so far only been observed.
Werner Heisenberg, who, along with Neils Bohr, formulated the Copenhagen interpretation, provides some particular useful insights regarding the nature of quantum reality in his book Physics and Philosophy. He writes, “Reality is in the observations, not in the electron.” This view is embodied in the Copenhagen interpretation which claims that a wavefunction is merely the mathematical embodiment of what we know about reality. Before we observe the electron, it exists in a ‘coherent superposition’ of all possible positions, snapping out of this haze when we measure its position. In this respect, the collapse is nothing more than the change in our knowledge about the whereabouts of the electron. What goes on behind the scenes, strictly speaking, lies beyond the scope of physics.
Crudely translated, this would imply that the cat is to be considered alive and dead at the same time! Naturally, this worldview, even though quite popular, does not sit well with a number of physicists and, yes, philosophers. Detractors question why fundamental physics should so closely be tied to human awareness. If we were not here to tinker around with laboratory equipment, would wavefunctions never collapse, or better still, not exist? Can bacteria or ants not be observers of quantum reality and a change in their ‘knowledge’ be associated with the wavefunction collapse?
For several years, the Copenhagen interpretation of QM held sway in scientific circles. But its primacy was challenged 1957 by an approach formulated by Hugh Everett that subjects our classical instinct to another major upheaval. (I seem to be getting into the habit of saying this. But, well.) The many-worlds interpretation (MWI) denies the occurrence of the wavefunction collapse. Instead, it views reality as a multi-branched tree, where each possible quantum outcome is realized. The concept of the universe is enlarged to include an infinite number of ‘parallel universes’ within a larger multiverse so that anything that can happen actually does happen in one of the innumerable versions of our universe. In one universe you are reading these words while in another you are waiting anxiously for the grand gala opening of your first play. It’s all happening out there!
Needless to say, I have only scarcely begun to realize the impact that this can have on our understanding of not only science but widely disparate disciplines like philosophy and spirituality. What if I were to put a gun to my head and pull the trigger? Would I be able to pull off this ‘quantum suicide’? If MWI is right, there will be a copy of our universe where I am alive and well. Should that mean my consciousness is, in essence, immortal? Quacks have been quick to jump on this bandwagon and have sought to use MWI to give credence to the idea of a soul that defies death and simply changes its ‘vessel’ as it hops from one universe to the next. Maybe that is how our ancestors tried to comprehend the strangeness of the universe we inhabit. Who knows!
But physicists are not in the business of mysticism and they have never really liked playing with odds. Some promising steps have been taken in the direction of separating spirituality from science through work on the phenomenon of ‘decoherence’. Decoherence provides an explanation for the appearance of the wavefunction collapse by postulating that much of the quantum weirdness of large objects ‘leaks’ from large objects because of their interaction with their environment. In other words, it is the framework which tries to explain how quantum uncertainty morphs into the well determined outcomes of classical experimental physics and our intuitive understanding of reality. MWI, with its decoherence updating, can prove to be an encouraging direction in the evolution of quantum theory.
Through the course of this debate, I have tried to emphasize how the resolution of one conundrum often leads to the genesis of a new one. When Newton tried to describe the ‘music of the spheres’, he could have scarcely imagined a world in which reality is neither deterministic nor viewed as a single unfolding history. Nevertheless, standing on the shoulders of such giants, we have been steadily hacking away at the myriad layers of our cosmic onion. As our intuition grapples with what is revealed to us, we will continue to reconsider our definitions truth and reality. The implications are exciting and manifold. But, as I will attempt to elaborate on in my next article, we must be careful enough to view them through the lens of reason and scientific analysis. One must sift through all the hoopla and take care to not be swept away by the wave. Doing so, we will realize that science does not undermine the beauty of the stars. Instead, it makes even larger the canvas of their mysticism. After all, it was Bohr who said, “Anyone who is not shocked by quantum theory has not understood it”.
Note: For the sake of simplicity (and to avoid making this article too tedious a read), I have discussed only two of the several contending interpretations of quantum mechanics. Interested readers can, obviously, choose to further this understanding. The following Wikipedia page should be a good starting point: http://en.wikipedia.org/wiki/Interpretations_of_quantum_mechanics.

I’m with You
It’s safe out there and now you’re everywhere,
Just like the sky.
And you are love,
You are the love supreme,
You are the rye.
And when you hear this,
You know it’s your jam,
It’s your goodbye.
Like I said you know I’m almost dead,
You know I’m almost gone.
And when the drummer drums,
He’s gonna play my song,
To carry me along.
Like I said you know I’m almost dead,
You know I’m almost gone.
And when the boatman comes to ferry me away,
To where we all belong.
Just like the sky.
And you are love,
You are the love supreme,
You are the rye.
And when you hear this,
You know it’s your jam,
It’s your goodbye.
Like I said you know I’m almost dead,
You know I’m almost gone.
And when the drummer drums,
He’s gonna play my song,
To carry me along.
Like I said you know I’m almost dead,
You know I’m almost gone.

Roads to Reality: The Clouds of Uncertainty
Physicists are an arrogant lot. And if Sheldon Cooper is any proof, they are usually quite happy being unapologetic about it. In an alternate universe, we probably pay our homage at the Cathedral of Science, with theoretical physicists presiding over as high priests. However, in our own version of the cosmos, I am willing to give them the benefit of a fertile imagination, given their knack of coming up with the weirdest explanations for everyday phenomenon. Therefore, it is a feast for the intellect when some of the brightest minds of a generation squabble over, quite literally, a dice.
Our classical sense of intuition tells us that in order to produce a change in a system (read ‘object’ if you are less scientifically minded) on the order side of a football field we will have to somehow negotiate the intervening space. That is what space does. We can shout, send a laser beam, or mail a postcard and wait for the cows to come home. Physicists and philosophers have a word for such a world view – local realism. Local realism posits that an objective reality exists even when it is not being observed and that an object can be influenced only by its immediate surroundings. It’s like what Winston Smith of 1984 would have us believe – “Sanity is not statistical”. Until the first two decades of the 20th century, no scientific development had challenged the locality of our universe. But all this was about to change.
The science of Quantum Mechanics (QM in all future references), developed primarily during the period between 1900 and 1930, breaks away completely with the tradition of a local, deterministic universe. It claims that one can not even know with certainty the position or velocity of a single particle, leave alone the evolution of the entire cosmos. Not only that, QM stipulates that prior to the act of measurement or observation, there is no point in even talking about such physical quantities. An electron could be here, in Andromeda Galaxy, or everywhere. Its behaviour can only be described by a fuzzy haze of probabilities, with no outcome being absolutely certain. Period. While relativity is counter-intuitive at best, QM is downright bizarre and malicious. It shatters our personal, individual conception of reality. God, it would seem, does like to play dice with the universe. And he rolls them blindfolded.
In order to interpret the physical properties of the micro-cosmos, QM uses a construct known as the ‘probability wave’. For example, if we are trying to study the position of an electron, the size of a wave at a given point in space is proportional to the probability that the electron is located at that point. But before the experiment is carried out and once its over, there is no way to determine for sure where it’ll be found. Identical experiments, performed under identical conditions, yield different results which agree with the probability profile of the electron’s probability wave. But is this wave thingamajig something real or just a convenient mathematical model that embodies all that we know and observe about the fundamental particles? Does quantum uncertainty tell us at that any moment particles simply do not possess a definite position?
This deconstruction of reality does not stop here. QM predicts the existence of ‘entangled’ particles that exist in a nebulous haze of uncertainty until one of them is forced to snap out of it when appropriately measured or interacted with. The outcome attained by any one of them is mirrored by each of the other entangled particles instantaneously, irrespective of the amount of space that separates them. If one decides to sport a pair of Ray Ban sunglasses, all the other entangled particles will choose to do so. They could be in two different corners of a room or at opposite ends of a galaxy – it doesn’t matter. This is dark magic or voodoo at its very best!
Naturally, this attack on the fundamental nature of reality did not sit well with Einstein. Over the course of many years, he mounted a series of ever more sophisticated challenges aimed at exposing the lacunae in quantum theory. He once reportedly said, “Do you really believe that the moon is not unless we are looking at it?” The stalwarts of QM were obviously not amused. So Einstein sought to provide a physical argument for this philosophical conundrum. In 1935, he published a paper with two of associates at Princeton – Podolsky and Rosen – which provided a theoretical basis for what has come to be known as the EPR Paradox. Using Heisenberg’s Uncertainty Principle, the authors argued that QM could not be a complete description of the physical reality and that a more fundamental theory is needed to understand it. For instance, it was argued ‘entangled’ particles displayed correlated properties simply because they had ‘hidden variables’ that programmed them to do so. Somewhat similar to two machines coming up with the same results even though they might be separated by a vast distance.
For several years the issue of who was right was left unresolved. Then in the 1960s, the Irish physicist John Bell showed that the debate could be settled experimentally. First in late 1980s and then later on through a series of progressively refined experiments, it has been proven conclusively that ‘spooky’ connections do exist between particles that defy our conventional notion of existence. What happens in Vegas doesn’t just stay there. Something like this should take your breath away! It affirms that a local universe may exist in our mind, but not in reality. What if our universe was nothing but a mirror image of an infinite number of entangled universes? As it is so poetically depicted in the movie Another Earth, is there the possibility that duplicate copies of our ‘selves’ exist? Would our choices mirror theirs?
The world according to the quantum is a strange place indeed. It forces us to abandon the idea of a local universe. It also throws out the window the notion of an objective reality – one that has always existed. The act of observation, hence, becomes closely intertwined with the process of creating the very reality that is being observed. In effect, this theory is incredibly efficient: it explains what you observe with mind boggling accuracy but prevents you from seeing the explanation. And therein lays the problem of reconciling our day to day experience of life with the weird microscopic reality revealed to us by quantum mechanics. Wasn’t life complicated enough to begin with?
Our society is structured according to the way we understand reality. Our definitions of truth, free will, justice are intricately tied to this understanding. To undermine its importance in the context of our own lives is to be deliberately short-sighted. And to ignore its implication, a fool’s paradise. So is that it? Is our reality merely a game of chance? Is Schrödinger’s cat really alive and dead at the same time? In my next article, I will try to dwell upon the different interpretations of quantum mechanics and what promises they hold for our understanding of that most elusive of phantoms – reality.
The first article in this series is available here: http://sleepingtablets.blogspot.com/2011/11/roads-to-reality-einstein-and-faith.html.
PS: If you are interested in the details of the arguments presented in the EPR Paradox, I suggest you read the original paper. It is not very long and Einstein's grouse with quantum theory has been expressed very succinctly. Here is the link to it - http://www.drchinese.com/David/EPR.pdf. Just ignore all the mathematics and concentrate on the parts mentioned on Page 1 and Page 4.

Roads to Reality: Einstein and Faith
PS — Somebody read this post and emailed me saying that this - http://www.internetservice.net/2011/10-things-that-einstein-might-have-tweeted/ - might be a fun addition to all the serious stuff here! I am inclined to agree : )
“There is but one truly philosophical problem, and that is suicide.” Thus begins Albert Camus’s seminal work in existential philosophy – The Myth of Sisyphus. The premise of the book is an ancient legend in which the Greek hero, Sisyphus, is eternally condemned to the task of pushing a rock up a mountain, knowing very well that it will roll back down. The million dollar question here – How does Sisyphus commit himself to a life without purpose, even bordering on the absurd? If his perception of reality were to change, would he see a silver lining? Camus acknowledges the significance of understanding the nature of the universe, but rejects the likelihood that such an understanding would effect our assessment of life’s worth. I beg to disagree.
It is true that reality is revealed to us through our experiences. But its arena is not just the world we inhabit. The overarching lesson from the past two centuries of scientific discovery is that our senses are often a misleading guide to the true nature of reality. In his book, The Fabric of the Cosmos, physicist Brian Greene aptly surmises this experience as – “gazing at a van Gogh through an empty Coke bottle”. Lying just beneath the surface of our perception is a world that will take our breath away. Through the tireless efforts of eccentric geniuses, mad scientists, and indefatigable innovators, we have been able to peel away layer after layer of this beautiful reality and come one step closer to understanding it. I feel that any assessment of existence that fails to incorporate the insights provided by modern science is not only incomplete but also juvenile.
Few scientists or their discoveries have achieved such ubiquity as Albert Einstein and his Theory of Relativity – with perhaps the notable exception of Sir Isaac Newton. A downside of such fame was that his statements and remarks were often blown out of proportion. So when Einstein claimed that he was religious, religious leaders latched onto his words and sought to use them in order to sanction their brand of God Almighty. But there is a quote that is frequently attributed to the great physicist – “Make everything as simple as possible, but not simpler”. Wary of being quoted out of context, he sought to express himself clearly on the subject, both for himself and for the sake of those who wanted a simple answer from him. So in the summer of 1930 he composed a credo – ‘What I Believe’ – that he released to a human rights group and later on published.
Throughout his life, Einstein maintained that underneath all the discernible laws of physics, there is a mysterious force, subtle and intangible, that is responsible for the harmony that we see around us. Veneration for this enigmatic power constituted his religion. He wrote, “To sense that behind anything that can be experienced there is something that our minds cannot grasp, whose beauty and sublimity reaches us only indirectly: this is religiousness. In this sense, and in this sense only, I am a devoutly religious man.” The mandate of science, according to him, was to hack away at this mystery and reveal to us those fundamental laws of nature that governed the ‘music of the spheres’. He gave no weight to the idea of a personal God who could meddle at whim in the affairs or mortal men.
A natural conclusion from this world view was Einstein’s belief in causal determinism. The world obeyed laws and we are just as bound to them as the planets that revolve around the stars. Were the immutable rules of nature revealed to us, it would be possible to predict with certainty if it will rain tomorrow at 4.15 in the afternoon and whether Mr. Sharma, a government clerk working in Jhumri Tilaiya, will choose to vaccinate his third child. Obviously, this was incompatible with the notion of free will, the very basis of moral behaviour and ethical freedom, and outraged several of his fellow physicists, including Max Born, who looked upon a deterministic world as downright ‘abhorrent’.
But that did little to dissuade Einstein. He famously quoted Schopenhauer in his credo – “A man can do as he wills, but not will as he wills”. Free will, in his view, was nothing more than a convenient construct that allowed civilised society to exist. Something that allowed people to rise above the ‘merely personal’ and live in a way that benefited humanity. “I know that philosophically a murderer is not responsible for his crime,” he said, “but I prefer not to take tea with him.”
In light of the groundbreaking success that his theories have had over the last 100 years, I found it a bit difficult to digest the notion that someone like Einstein could be religious. In fact, he was more critical of the fanatical atheists who “lacked utter humility toward the unattainable secrets of the harmony of the cosmos”. But that is when his words came to the rescue. Einstein believed that only a person thoroughly imbued with an aspiration for truth and understanding can do science. The source for that inspiration, however, lies in the sphere of religion. In other words (or more precisely, in his words), “science without religion is lame, religion without science is blind”.
But there was one religious concept that he could not accept. The bone of contention between religion and science, Einstein argued, lay in the concept of a personal God – someone who could randomly alter the course of events once they have been set into motion. A scientist on the quest for discovering the laws of reality must reject the notion that divine will, or for that matter human will, can influence this cosmic causality.
But even during the course of his life, a new sun was looming on the horizon of modern science. Few discoveries have so drastically affected our understanding of the machinations of the universe in recent times. Quantum Mechanics and the uncertainty woven into its fabric was about to deliver a knockout punch to the idea of a deterministic world. Deeply troubled by this assault on the very nature of reality, Einstein mounted a series of attacks against this emerging field in his later years. Physicists, he would emphasise, are not bookies and physics is not in the business of determining odds. Did he succeed in his mission or has our understanding been subjected to yet another upheaval? What implications does Quantum Mechanics have for our grasp over reality? More importantly, is this the only reality that exists? I will try to elaborate on some of these questions in the next article in this series.
“There is but one truly philosophical problem, and that is suicide.” Thus begins Albert Camus’s seminal work in existential philosophy – The Myth of Sisyphus. The premise of the book is an ancient legend in which the Greek hero, Sisyphus, is eternally condemned to the task of pushing a rock up a mountain, knowing very well that it will roll back down. The million dollar question here – How does Sisyphus commit himself to a life without purpose, even bordering on the absurd? If his perception of reality were to change, would he see a silver lining? Camus acknowledges the significance of understanding the nature of the universe, but rejects the likelihood that such an understanding would effect our assessment of life’s worth. I beg to disagree.
It is true that reality is revealed to us through our experiences. But its arena is not just the world we inhabit. The overarching lesson from the past two centuries of scientific discovery is that our senses are often a misleading guide to the true nature of reality. In his book, The Fabric of the Cosmos, physicist Brian Greene aptly surmises this experience as – “gazing at a van Gogh through an empty Coke bottle”. Lying just beneath the surface of our perception is a world that will take our breath away.
