Advertisement -- Notebook of a Signal Processing Engineer

Palakkal Times

My time is limited. I am already exhausted in life. I have a mountain of frustrations in my mind. Yet, I can't help writing more, again, "to feel the inexorable pleasure of writing".  I have started another blog on signal processing, more on my professional front. I had started some time before, but only now I published something relevant. You can access my blog at http://sandeeppalakkal.wordpress.com/

Thanks for your support,

On Buddha's Problem, from a Contemporary Perspective

Once upon a time I was so fascinated by teachings of Buddha. I often say that I am a frustrated nihilist. I became a nihilist against my will, when I lost my belief in everything in life, all values propagated by the society, and every moral teachings. Yes, I have gone through a time like that. It was in those days I read so much, seeking a foundation of thoughts and values for me. Buddhism was the one of the most important teaching that grabbed my attention and admiration. Here, I would like to talk a little bit of Buddhism and ponder over it, for no particular reason. All the opinions expressed below are personal, and I claim no scholarly value for them. Before beginning, I would like to complete the story of my nihilism by saying that I could never be satisfied by any set of values or teachings. The more I read, the more I sought, the bigger a nihilist I became. Was it my fault? Incapacity to believe -- Is this my fault? Finally, I was bored of my own nihilism. I could no longer bear it. One day, I realized that my nihilism itself had started to become frustrating. Ever since, I considered myself "a frustrated nihilist". And ever since I became free of the need "to seek a foundation of values and thoughts for me". Probably, ever since, I started "to live", freely, without conceptions.

Now, coming back to Buddha's teachings, I would liketo  look at the heart of the problem Buddha tried to analyze. There is a whole story and speculations surrounding Buddha. However, my objective is not to tell or re-tell those stories but actually to look at Buddha's problem and try to understand it from my time and perspective. Understanding Buddha's problem from his own time is an impossible task for me, and can possibly be done only by specialists in Buddhism and its history.

Probably, I have to begin by asking what is the objective or meaning of human life, though I consider it as the most absurd question in heaven and earth to ask (I have not seen hell; therefore, I leave the possibility of asking this question there). Distancing myself from all the available scriptures and previous knowledge, I begin by looking at a more functional level -- the level at which life actually unfolds. I would like to look at how everyone lives in the world. From an animal's perspective, life is all about eating and breeding. When it does not eat or breed, it either takes rest or just play around aimlessly with its fellow animals. These statements about animals may be incomplete, but I am comfortable in handling incompleteness. I rather continue to look at humans who differ from animals in their superior intelligence. In the case of humans, the first two points I said about animals are valid, with a slight modification in the second -- eating and mating (more often for pleasure than for breeding). Regarding the third aspect, the modern humans have almost forgotten to play around with their pals. Except the children, they are "settled" and spend most of their leisure time "resting" in front of television. Apart from these, their other leisure activities or entertainments in general are transitory and have no particular objective. So, let us try to learn from the modern humans what their objective is by looking at how they spend most of their time. Majority of the time is dedicated to "some" job, which they are not particularly interested in but do solely for earning money (a more decent way of putting it is "to make a living") and for the joy of upholding it as a status symbol (In a charming voice she introduced herself, "Well, I work as a ******".). Of course, I am mistaken if I oversimplify the objective of job or work in the modern human life as money-making and attaining an identity. More than that modern humans work so that they can secure the future, marry off their girls decently, meet urgent situations like sickness etc. (Does it again it boil down to money?) I think that we can safely say that the objective of modern life is to lead a safe, comfortable life without much troubles. Money is considered as the means by which these objectives can be achieved. Since humans have not evolved enough, they quite often forget this and pursue money-making as their sole objective. (When one tries to achieve this in little time, one tries to do things like "3G scam", and, if unlucky, ends up in the Tihar jail.) There are exceptions, though. There are people who are more lazy and do not even try to lead safe and comfortable life. They just booze and kill each other in the street. On the other extreme, there are people who work for more (they say) noble objectives like fame, service of the poor, building up own nation, etc. There are more selfish people who aspire to become a movie director, actor, television anchorman, painter, novelist, model, engineer, etc. There are other fools who aspire for academic excellence, like obtaining a Ph.D. from a well-known institute, or for achieving technical competence, like struggling to be an excellent engineer!

Having understood more or less the meaning and objective of modern life, I would like to look at the next aspect in this realm, which comes for sure but uninvited. Summarizing the above paragraph, the objective of life is mostly to "achieve" something. This "something" changes for person to person, country to country (maybe), and time to time. But a major difficulty is "to achieve something permanently". This seems to be (I say "seems to be" because I am still skeptic -- my weakness) impossible. To understand this impossibility, I must have to ask another stupid, age old question: "who am I?". However, because I cannot surpass my own skepticism, I am rather tempted to ask "what am I?". Again, without resorting to all the metaphysical stories written in the sacred text books, I would say, "I am my body, my thoughts, my feelings, my knowledge, my surroundings, my family, my education, my fantasies and so on". Put in one sentence, "I am a bunch of abstract and material elements, which are impermanent and, by and large, irreconcilable". The irreconcilability of the elements which constitute the "I" is an interesting topic for further discussion. But I am interested in the other "fact": the impermanence of every element that makes up "I"! This means that whatever I think, whatever I do, whatever I plan (no matter how diligently I plan), my life and my action and "I" are impermanent. However well I live, however devoted I am towards my life, however noble my pursuits are, I am not permanent... my power will slowly decay and, finally, one day, I have to die. I will be gone, my time will be gone, my work will be gone, my family will be gone, and my world will be gone. This impermanence causes an unsolvable uneasiness in every human being. Knowledge of this very fact makes one to be aware of the futility of everything one strongly attaches oneself to. This weakness of oneself causes eternal suffering -- "dukkha". Is there any solution? Is there any possibilities of salvation? How can I end my suffering? This is the heart of Buddha's teachings.

I admired Buddhism mostly because the way Buddha arrived at his problem, which he considered as the only problem on earth worth solving! While other ancient thoughts start with the solution (faith and salvation), Buddha starts with the problem! And for Buddha, every other metaphysical questions were only sub-problems or no-problems.

Paradox -- yet another one

Yet another paradox in my life (popular among Ph.D. students, but jut repeating here):

In my research, I am searching for at least a single problem to solve; 
In life I have only problems, which I don't know how to solve.

Beyond words

'Perfume -- The Story of a Murderer' is a very good movie, though I would not say that it is an exceptional one. It is the story of a man who had a talent for sensing odour, and the extent of his talent goes beyond the usual human possibilities. For example, he knows the smell of iron, frogs, wood, water, and almost anything around his world. Besides, to sense the smell of something, he does not have to go near it; he can sense it from a distance. Even his sexual attraction towards a girl is manifested through his desire for her body odour, which she loses immediately after she dies. At some point of the movie, he realizes that his body does not have any smell of its own. For him, he is the only person in the world 'who' (or rather, 'what') does not possess a smell of his (its) own. Later, he falls into an obsessive struggle to extract the smells of beautiful women, and own those smells for himself. How? That is the story of this film.

In fact, I have no intention in talking about this movie itself. I am more interested in something else. The above character learns to speak lately in his childhood. Up to the age of ten or twelve, he is unable to convey anything through words. He senses the world through odour. And for him, anything around him is distinguished by its odour. When he finally learns to speak, he realizes that words were quite incapable of expressing the reality around him, what he has seen and felt. He could not find equivalent words for many things in the world as he knew it. It is this point I am interested in.

We all see things around us and feel many things inside our minds. And we identify almost all things within and outside us by words. Probably, man has been able to make his distinguishable mark on earth (or is he/she?) because of words. Thoughts originates as words (or do they?). Without words, no thoughts, no discoveries, no stories, no science, no news, no advertisements, and no "culture". But how do we learn words? Someone teaches us! We understand the world around us through the words someone has taught us! How strange! How mistaken we possibly could be about things around us! Shouldn't we learn words through nature? Why are we not taught like that? What if we are confused between things in the world because we identify them with wrong words? Do we have words for everything around us? At least for every feelings we have? What if we think that we are sad when we actually feel a mix of sadness and happiness? This happens to me many times! What are the words we use for our feelings? Anger, happiness, sadness, melancholy, jealousy, lust, serenity, and what else? Do we have feelings which do not have equivalent names? When I say I am angry, is there only one kind of anger? What if I can have many types of anger but I wrongly identify all of them as just "anger"? Have I really understood what anger is? (If you think I am writing some nonsense and I have gone nuts, you might as well be wondering "does he really understand what he is writing"?)

Buddha said "truth is beyond words" and what one needs is not indoctrination, which is merely knowledge of a few words, but a "transmission outside doctrine, with no dependence on words". Saramago has shown us what a person who can see sees in a world, where everyone is blind. Modern science says we have evolved in order to survive the hardships that we come across in the world. What if we have evolved in such a way that we cannot see what we must not understand? Put together, man is limited, imperfect, and blind in some sense.

Today, someone was wondering if he could realize an ideal lowpass filter (for non-techies, tuning of your radio in a perfect sense, without any extra interference). And by discussion, I could make him see why he could not! The trade-off between time and frequency characteristics, the uncertain principle and the practical non-realizability of infinity! But even then, we can cleanly listen to our radios, watch T.V. and talk to our friends over mobile phones! All these situations need filters. He said "Signal processing is great! Our technology is great!". I replied him "It is the opposite. We are imperfect. Even with imperfect technology, we can do many things that we are doing. We cannot sense any imperfection introduced by technology in radio music, T.V. shows, or mobile conversations. This is because, I repeat, we are limited and we need only limited technology". Will you agree with me? Without technology, we cannot see the infra-red radiation. When we see it by the help of technology, we feel that the technology is excellent. On the contrary, we cannot perceive the imperfection of the technology because whatever imperfections our technology suffers from are all due to the imperfection possessed by us!

Starting from a movie, I have gone to technology. I do not know what is happening to me. Probably, I have really gone insane! Nonetheless, I still dare to wonder what is beyond words?.

Becoming human!

Finally, after a short gap, I watched an excellent movie two days back. I watched it on DVD, along with my wife, and throughout the movie, she kept wondering "how somebody could conceive such different ideas!". Of course, unlike me, she had never got an opportunity to go beyond the usual Hollywood/Bollywood/Malayalam/Tamil shit! But, now, gradually she is ....

The Movie
The movie that grabbed our whole attention for two hours is "The Terminal". It is directed by Steven Spielberg. And Tom Hanks plays the protagonist Viktor Navorski. Tom Hanks has been one of my favourite actors -- how can I ever forget his class performance in Cast Away, The Road to Perdition, Philadelphia and Forrest Gump!

Well! To summarize the movie, Viktor visits New York for some purpose (that's less important, I think) and he belongs to a fictitious East European country, called Krakozhia. By the time he reached the New York airport terminal, civil war erupts back in his country and the government is overthrown. The United States has not recognized the new government and has cancelled all visa given to the citizens belonging to Krakozhia. Consequently, Viktor cannot enter America. Thus he happens to be "a person with no country", and is simply "unacceptable" to America. He cannot fly back to his country until the war is over. He is forced to live in the airport terminal, his passport being confiscated by the authorities. He is left with no money, no place to stay, and no work. On top of it, he knows very little English!

What I have described is the beginning, probably spanning the first twenty minutes, of the movie. The rest of the movie is about his struggles to survive in the terminal. I interpret the story as the struggle of a lonely man, thrown into a completely strange and, above all, indifferent world. His only objective is his survival. He has no identity, no society, no affiliations and associations, and no friends. Have you ever thought what a man would do in such circumstances? Viktor never resorts to anything immoral, but keeps his dignity as a human being throughout. Naturally, the initial concern must be food, and in the modern society, this means money. He discovers several opportunities in the terminal to earn money (watch the movie -- I don't want to kill your pleasure of anticipations). Later, his efforts are to identify and get himself identified with his surroundings. That is to say, to learn the language, to communicate with others, to make relationships, and so on. He has to begin everything from the scratch, like a new-born child! He has to learn how to become a human being. Fortunately, Viktor is admirably creative in overcoming all the difficulties.

Surely, this movie is something I am not going to forget in my life. My wife enjoyed it very much though it was pretty different from her usual taste!

Pirates 4

I watched the "Pirates of the Carribean 4" with a lot of enthusiasm. Well! Jonny Depp as Jack Sparrow ("there should be a captain somewhere in there" :)) was excellent, but the role of Angelica demanded very less from Penelope Cruz. However, the scenes in which both come together were very nice. The film had nothing special which could exploit the 3D vision! Except for a few scenes, the movie experience was merely 2D.

But we relished the coolness which the air-conditioners provided at INOX in this hot summer in Chennai :)

The Creator -- A Poem

The Creator
--------------------

Does God exist,
The one who created the world?
I don't know! But I know:
India won the world cup cricket.
All the prophecies of media came true.
And the media create the world!

A Poem -- My Writings

My Writings
--------------------

Thou thinketh:
I entered the family life
Hence banished from the normalcy of my life
And there would be no more of my writings.

But I say unto thee:
Normalcy had never existed in my life
And my writings yearn for infinity,
No matter the world does not exist!

Eurocentrism, blah blah blah....

Eurocentrism is a conscious or unconscious perspective that whatever coming from the Europe is right and true. This word had been prevalent in the last century, especially during the European colonialist era, and was used critically. So why I got interested in it, and what are the interesting things about it?
I got interested in this word because of some reasons. Recently, I heard one of my friends quoting from a speech he listened to: "...whatever coming from the West (from the Indian point of view, the West means the European and American) is regarded as science and whatever coming from the east (Asia or India) is considered as ___ (the person could not remember the word; it must be pseudoscience, metaphysics, religious, spiritual, or even nonsense)...". Whoever the speaker be, I felt this was incorrect. Science has a set of fundamental rules to accept something true. They include objectivity, repeatability, etc. For example, the basic laws of motions, discovered by Newton applies all over the world. The same must be true for anything that can be called science. And if somebody claims something is science, which is not repeatable or objectively verifiable, I will look at him with suspicion. For example, in the same talk, the speaker claimed that "it was scientifically proved that water has memory". I don't know the truth about this, but I feel suspicious! On the other hand, I have a question: do we accept everything coming from the West as true? For example, the movie Jurassic Park comes from the West (though from the United States). But do we consider it true? It's just a fantasy, according to all of us, isn't it? There are numerous science fiction coming from the West; do we consider them true?
Now a days, we have so much of exposure to what is going on around the world. I followed Prof. Richard Dawkins in Youtube. I found him talking to many religious people, taking part in debates and just talking science to us. One of these videos [1] I would like to mention here is the one where he talks with the Indian holistic healer Mr. Deepak Chopra about the relation between quantum mechanics and his so called quantum-healing process. But Mr. Chopra soon realizes that he can't argue with an eminent scientist like Prof. Hawkins, who is also a man of an extremely rational mind. Then Mr. Chopra says that he never claimed any relationship with the quantum mechanics, he used the word "quantum" only as a metaphor, and in fact, it was quantum mechanics that had hijacked the word "quantum". In a later video [2], Chopra says Dawkins point of view is "mechanistic, Newtonian, outmoded and obsolete". Here, I am confused! Who is outmoded? Dawkins or Chopra? But our point is different: is Dawkins Eurocentric just because he argues rationally, or just because he comes from the United Kingdom? I don't need to explain this point. You catch on Dawkins on Youtube and Google videos, and you will be able to judge.
A third reason why I was tempted to know more about Eurocentrism is the following. One of my friends sent me a speech titled as For America to Live, Europe Must Die [3] by the Native American activist Russell Means (according to him, he is not the Native American, which is a misnomer, but he is the real "Indian"!). He claims that all the European concepts like modern science, modern physics, modern philosophy, Marxism, capitalism, etc. have a hidden agenda of European cultural expansionism, and the proponents of the above fields were trying to expand Christanity in disguise: a version of the "secularized" Christianity. He views Karl Marx, Issac Newton, John Locke, Adam Smith, Decartes, and every other European intellectuals as travellers on the same boat: expand the European culture! Of course, expand against the Native American, Indian (my India:-)) or other cultures. He says, for example, that "European culture itself is responsible [for the sufferings of the Native Americans]. Marxism is just the latest continuation of this tradition, not a solution to it. To ally with Marxism is to ally with the very same forces that declare us an acceptable cost." I understand that this is a cultural argument. He says "After all, Europeans consider themselves godlike in their rationalism and science. God is the Supreme Being; all else must be inferior." This is a religious argument. So, I think this third point which prompted me to think about Eurocentrism is the matters concerned with identity, religion and culture. I have come across the same opposition against the "European thought" such as science, mathematics etc. among some people with Nationalist sentiments in my India, too. The Islamic problem of identity and religion, and their struggle against "the West" in the Middle-East also can be looked at from the same perspective. However, isn't it ridiculous to look at every thing European, including modern science, sharing a common ground and cling obstinately to culture and identity?
In my short search to find out what was Eurocentrism, I came across another interesting fact: Eurocentrist attitude towards Indian mathematics. Forget the nonsense of the Vedic Mathematics, which is a system "consisting of a few isolated tips, totally lacking in coherence and conceptual utility" [4] or "is only an assortment of tricks, based on simple algebraic principles" [5], and whose vedic credentials are disputed. We are talking about the "real" Indian mathematics. An overview of the Indian and Kerala mathematics of ancient times, and how the European historians had neglected and rejected to recognize the Indian contribution to mathematics, is given in Indian Mathematics: Readdressing the Balance [6] by Ian G. Pearce. This, I think, a very good and acceptable example of Eurocentrism.
I would like to end this post by discussing what the Slovenian leftist intellectual Prof. Slavoj Zizek [7] given to the online magazine Bad Subjects. He admits the existence of Eurocentrism and the Christian influence on it (even otherwise, there is no dispute on its existence or the Christian influence; but on what grounds can we attack it is the question). But he says that, as modern humans, we can't help accepting the concept of "universalism", which is clearly a European proposal, influenced by Christianity. Universalism is an attempt to show the world that there is something applicable to every human being, in any culture, religion and ideology. For example, the concept of human well-being or ethics, is universal. If you define separate ethics for Europeans, Indians, Native Indians, Christians, Hindus, Muslims and the Buddhists, then we end up in chaos (the modern world is in such a chaos now!); we'll not be able to define it! I remember Erich Fromm proposing the same idea of universalism in his book Man for Himself. 
I think the only answer to the human problem is by accepting the axiom of universalism. More than belief, identity and culture, we have to accept universalism, when defining at least the concept of human well-being. Similarly, we must accept the European(?) notion of objectivity, at least in science, so that its pursuit is satisfied. However, when these concepts are applied to human society, I think we must be careful. There, humanity, not objectivity or materialistic view, is important. Differing from Russell Means I would say that Marxism is not materialistic. It is, on the contrary, to look at the humans as humans, not as workers, and to free them from the exploitations of the forced labour and the powerful class. Marxism dreams [8] of a world, where every human being is a poet!  We can argue its Utopian edge, whether China or Soviet Union could materialize this vision, etc. sometime else.
At the same time, we must not eradicate the culture and identity of some race or ethnic group, and any attempt to do so will meet adverse and dangerous results. Moreover, concepts of universality is not only European or Christian; every other culture or religion contains it, in some way or the other. We must assimilate the good points from the individual cultures, after scrutiny, and dream of the rise of a modern, intellectual (more modern and intellectual than us) race of humanity.
