I am my own reader
I read therefore I am
- First, by following breathlessly, the events and the characters without stopping to notice the details, the quickening pace of reading sometimes hurtling the story beyond the last page — as when I read Vonnegut, Maugham, O'Henry or Salinger.
- Secondly, by careful exploration, scrutinising the text to understand its ravelled meaning, finding pleasure in merely the sound of the words or the clues, which the words did not wish to reveal, or which I suspected was hidden deep in the story itself, something too terrible or too marvellous to be looked at.
The second kind of reading — which had something of the quality of reading stories — I discovered in Lewis Carroll, Vikram Seth, Vassanji, Tagore and Nabokov. Reading, to me, set one free, it gave one a freedom to explore thoughts and the world outside the context they lived in. This has its retributions in the political world we live in, from the banning of writers like Rushdie and Taslima Nasreen to the censorship of countless authors ranging from Neruda to Gorky over the years. But not only totalitarian governments fear reading. Readers are bullied in school yards and in colleges as much as in government offices and prisons.

Gandhi fought against foreigners and the natives
Even after conceding that Gandhi fathered the nation, Swagato Ganguly has blamed the Mahatma (The God That Failed, Oct 1) for much of India's ills. Yet, in the admission of his fatherhood lies the key to understand the Man of the Millennium. A basic feature of Gandhi's life and politics was that he was not just a freedom fighter like Nelson Mandela. Even as he opposed the British, Gandhi wanted to ensure that the Indians were ready for their freedom. It has to be remembered that the most harmful effect of colonialism was not economic exploitation, but cultural subjugation. Gandhi's first battle was against this conviction of inferiority which enabled a few Britishers to rule over many Indians. His objective was to instil a sense of self-respect among Indians by making them feel proud of their Indianness. As William Shirer, the author of the Rise and Fall of the Third Reich writes in his book on Gandhi, when he called on the Mahatma, he found him sitting on the floor plying the charkha. Gandhi asked Shirer whether a chair should be brought for him, but Shirer declined and sat on the floor. The episode is symptomatic of Gandhi's politics. He wanted to demonstrate that Indians sat on the floor (and ate with their fingers and had their own dress codes) and were not ashamed of their customs. If the whites wanted to join them, they would have to do so on these terms, and not the other way round. It is this attitude which made him discard western clothes and tell journalists, who asked him how he felt meeting the King in Buckingham Palace in his meagre attire, that the monarch was wearing enough for both of us. Arguably, in his endeavour to emphasise the distinctive Indian personality, Gandhi took his anti-western stance too far, to the dismay of Tagore and Nehru. But, then, the Mahatma was not a man of compromises. It has to be remembered also that, to him, the fight with the British must have seemed an endless struggle. Gandhi, therefore, fought on two fronts against foreigners and the natives. And the latter had not only to be taught to be self-reliant and worthy of respect by weaving his own clothes but also by cleaning the latrines, a lesson which the country doesn't seem to have learnt even now.Gandhi may have also calculated that to make his non-traditional attitude towards untouchabi-lity acceptable, he would have to identify himself closely with eternal India through his dress, religiosity and austere lifestyle. An obviously anglicised person such as Nehru wouldn't have been able to do this. In the process, Gandhi had no alternative but to turn his face against western civilisation, a yet to be attained good idea. Had he praised industrialisation and preferred allopathic medicine, he would have been a charlatan to the masses. His was a canny strategy to topple an empire, leaving the future to take care of itself. The writer is a political commentator

Tolerance, acceptance and sympathy.
Religion is not talk, or doctrines or theories, nor is it sectarianism. Religion cannot live in sects and societies. It is the relation between the soul and God; how can it be made into a society? ... Further, all religions, with the sole exception of Hinduism, depended on the historical veracity of their founders or prophets. This invariably led to conflict. Tearing apart the prophetic tradition, he debunks the very motives of all prophets (with the exception of the Buddha). All prophets were moved by external motives to expect reward from the outside, meaning the material world. Their actions were not unselfish. Their language may have been highly evolved but their intentions were highly suspect...
Vivekananda derived the idea of a common universal faith from Sri Ramakrishna. In a speech delivered in New York, and subsequently published under the title, My Master, Vivekananda speaks of Sri Ramakrishna's attempt to know the truth of all other faiths ... ... Vivekananda did not experience this oneness of faiths like Sri Ramakrishna. His attempt remained confined to the intellectual plane and lacked the intensity of living another man's faith with one's `whole heart'. Between Sri Ramakrishna and Swami Vivekananda, the disparity in method to arrive at the same conclusion made all the difference. Like Jesus, Sri Ramakrishna was after all the pure sort, unencumbered by history or context, but immensely rich in experience. Vivekananda was like Paul, the thundering sort, who had to spread the light quickly and effectively. He understood well that religion was not an intellectual activity but an act of realisation. But he was often impatient. Hinduism as a tolerant and all-embracing faith remained for him an aspiration, never an experience.

Sob Story
- In healthy eyes, the cornea is continually kept wet and nourished by basal tears.
- The second type of tears is reflex tears that attempt to wash out irritants that may have gotten into the eye.
- The third category, emotional tears, is increased lacrimation due to strong emotional stress or pain. Tears brought about by emotions have a different chemical make-up than those for lubrication.

The Moment of Complexity
"The Moment of Complexity is a profoundly original work. In remarkable and insightful ways, Mark Taylor traces an entirely new way to view the evolution of our culture, detailing how information theory and the scientific concept of complexity can be used to understand recent developments in the arts and humanities. This book will ultimately be seen as a classic."-John L. Casti, Santa Fe Institute, author of Gödel: A Life of Logic, the Mind, and Mathematics

String theory
The Hindustan Times October 2, 2005
The new idea was to assume that the basic entity was a string, not a point particle. The string could virate in different ways, just like a sitar string does.The different resulting notes are the different kinds of particles, electrons, photons etc. There are six extra dimentions in string theory. These are believed to be curled up in small size, so that they have not been observed yet. A beatiful feature of string theory is that its differnt facets are closely tied together in tight logical consistency, so that progress in any area leads to ramifications for the whole subject.

Remote Viewers
Every breath you take is a creative act. The molecules in the air are random and chaotic. If they happen to enter into your body, they magically acquire a purpose and an identity. Could any act be more creative?
Consider what happens to a single oxygen atom as you breathe it in. within a few thousandths of a second it passes through the moist, nearly transparent membranes of the lungs. It immediately attaches itself to the haemoglobin inside one of your red blood cells. In an instant, a remarkable transformation occurs. The blood cell changes colour, from the dark blue-black of oxygen starved haemoglobin to the bright red of an oxygen rich haemoglobin, and a stray atom of air suddenly becomes YOU. It has crossed the invisible boundary dividing you from the rest of the universe.
Each of us is balanced between the infinite and the infinitesimal. The same protons found in the hearts of stars, which have lived at least 5 billion years, take up residence inside us. The neutrinos that streak through earth in a few billionths of a second are part of us for a brief instant, too…Remember that you are a flowing river of atoms and molecules collected from every corner of the cosmos. You are an outcropping of energy whose waves extend to the edges of the unified field.Deepak Chopra
It might not be so incredible to declare that the compositions of all 6 billion human beings as well as the thousands of other species on Earth are, in fact, indistinguishably intertwined, making us soulmates in more ways than one.
Consider this: When a bacterium, weed, starfish, peacock, dog, cat or human dies, decomposition sets in. in the process, the atoms that constitute the body are released into the atmosphere, and they mingle freely, getting interspersed over wide geographical areas. Some might get reconstituted in a short period of time, becoming a part of another, or the same species. Other atoms continue to free float indefinitely, may be for years or even decades, before they submit to another composition. That makes us all parts of one indistinguishable whole, with each having at least some of the ingredients of the other.
Bill Bryson in A Short History of Everything talks about the pervasive nature of atoms:
Atoms are fantastically durable. Because they are so long-lived, atoms really get around. Every atom you possess has almost certainly passed through several stars and been part of millions of organisms on its way to becoming you. We are each atomically so numerous and so vigorously recycled at death that a significant number of atoms – up to billion for each of us, it has been suggested – probably once belonged to Shakespeare. A billion more each came from Buddha and Ghenghis Khan and Beethoven, and any other historical figure you care to name… so we are all reincarnations – though short-lived ones. When we die, our atoms will disassemble and move off to find new uses elsewhere – as part of a leaf or other human beings or drop of dew. Atoms themselves, however, go on practically for ever.Jahanavi Shandilya
Not only that, they were also exactly in one and the same place – the initial singularity; the primordial atom. Nor could they have been anywhere else since there was no other time or place to be in. Then again, we’re connected in another way too. Consider the air we breathe. It’s just matter in a gaseous form consisting of 78% nitrogen, 21% oxygen, less than one per cent carbon dioxide, some water vapour, dust and pollutants and trace amounts of various elements.
In fact, nothing could be dissimilar to ourselves. Yet once this air enters our lungs it oxygenates the blood, which nourishes the tissues, and once it leaves the lungs it carries away all the carbon dioxide wastes taken from the tissues. It’s safe to say the air around us not only becomes part of us continuously but contains a part of us in it as well all the time. That’s how connected we are.Mukul Sharma
The uncertainty principle implies that particles can come into existence for short periods of time even when there is not enough energy to create them. In fact, they are created from uncertainties in energy. One could say that they briefly borrow the energy required for their creation, and then, a short time later, they pay the debt back and disappear again. Since these particles do not have a permanent existence they are called virtual particles. And even though we can’t see them, we know that these particles are really there in empty space because they leave a detectable trace of their activities that have been very accurately measured and described.Mukul Sharma

The Anthropic Principle
In The Hitchhikers Guide to the Galaxy, the Deep Thought computer announced that the answer to the ultimate question of life, the universe and everything was 42. Contemporary physicists are finding themselves just as frustrated as the hyperintelligent race of beings who built Deep Thought after discovering that the ultimate answer to their questions turns out to be a set of meaningless numbers. Many scientists conclude that the answers are contingent on biology and the facts of life. Imagine if the values of one or two of nature's fundamental constants were slightly different, say the strengths of forces that hold atoms together. One consequence might be that the Earth's oceans would regularly freeze. Water — essential for life — is unique in being lighter as a solid than as a liquid. So ice sheets float and form an insulating layer that stops the deeper waters freezing. If water was more conventional then the primordial oceans would never have stayed liquid for long enough for life to evolve. But then of course we would not be here to ponder our good fortune.
This is the point of the anthropic principle, which starts from the fact of our existence and then argues backwards to claim that the precise properties of the universe that emerged from the big bang had to be those that made the eventual emergence of humans inevitable. The unique properties of water depend on an exquisite level of fine-tuning of the fundamental constants. So why are these constants just right? Because if they weren't we wouldn't be here. There are lots of other fine tunings. Carbon, also essential for life, is made in stars by the fusion of three helium atoms. It is only due to an extraordinary "coincidence" in the resonant energies of helium, beryllium, and carbon that stars make lots of carbon. Change the resonant energy by just 0.0001 per cent and no carbon. Proponents of the anthropic principle claim it is pointless looking for theoretical explanations for the precise values of the fundamental constants; they are what they are because if they weren't we wouldn't be here. Opponents claim that the principle betrays a lack of imagination for assuming that other forms of life wouldn't be possible. But this is harder to sustain when considering some of the more cosmic consequences of tweaking the constants. If the weak force that binds atomic nuclei had been just a bit weaker, all hydrogen would have turned to helium without making any of the heavier elements. If the strong force had been a bit stronger, the universe would not even have had any atoms.
New research is making even the sceptics grudgingly accept the anthropic principle. A paper by Mario Livio and Martin Rees, the astronomer royal, explores the value of the cosmological constant, a measure of how much energy is contained in empty space. Without this value being tweaked to an extraordinary level of precision, the universe would be filled only with huge black holes or entirely empty of stars. But who's doing the tweaking? Another reason scientists are wary is that it seems to reverse the Copernican revolution and place humankind at the centre of the universe. Even worse, it could allow creationists to bring the G word back into science: a God to tweak all those knobs to make life possible. But if God is needed to tweak the universe's knobs then who was there to tweak God's knobs? Physicists such as Martin Rees and Stephen Hawking prefer another scenario whereby an infinite number of universes exist, each with different values of the fundamental constants. In just a few of them the constants have taken on the right values for the creation of stars, life and evolution.
For a biologist like me the anthropic principle has a persuasive charm. Physicists have long claimed that biology reduces to chemistry and chemistry reduces to physics. But now physics reduces to biology! To explain the values of the fundamental constants physicists have to look not at their equations but at the structure of the eye or the brain or the building blocks of life. Who knows which fundamental constants take their value from the fact that fish had to propel themselves through water before evolving into intelligent tetrapods like us. Biology explains everything.
