Greatest Biologist of All Time & Aristotle's Lagoon

Armand Lerio gave a fascinating talk on Edge. According to him, it's not Darwin but I disagree. Like the premise of Steven Johnson's book Where do good ideas come from?, knowledge is cumulative and yes, Aristotle was the pioneer. I believe being a pioneer doesn't make one the greatest. Darwin's genius was in the world of abstract biology, he quantified biology with a greatest abstractions of all.

"So what do I find when I look at Aristotle? Well, for me the thing that fascinates me about Aristotle is his discussion of the soul. Now, I know that's a strange thing to say because when we talk about souls, we immediately think of the Judeo-Christian conception of the soul which is some strange non-physical entity that hangs above your head, or something, and survives you after death. That's not what Aristotle meant, not at all.
Aristotle thought that soul was central to life. And there's nothing vitalist about it, there is nothing metaphysical about it. It's hard to get a grip on what he meant, but it's a resolutely empirical kind of concept. What he meant was something like this: he says all living things have a soul, and when they die, the soul disappears. So none of that nonsense about the immortality of the soul. Plato thought souls were immortal, many people believed that souls were immortal, but Aristotle is clearly using soul in a very special, and technical, and new sense. It's the moving principle of life."

Happy Birthday Max

Maximus is five today!!
Max with his new Lion; all I said to him today am was - Max, this is Lion. Now, he "knows" the Lion and picks the Lion from his toy pile whenever I ask for it. He is much smarter than his dad would ever be. 



Each passing birthday brings about that silent anxiety... this little guy taught me about life, love and happiness. In the past five years, an ophthalmologist in him etched a beautiful perspective into my eyes. Through this eyes, everyday I live my childhood again filled with splendor of innocence and the joy of life. He became my Darwin; showed me how I need to evolve. He became my God; taught me hope. There is grandeur in this view of life. I love you Max until my last breathe and I hope we take that breathe together. 






Love and Friendship - C.S.Lewis

"A friend's love free from all duties but those which love has freely assumed, almost wholly free from jealousy, and free without qualification from the need to be needed, is eminently spiritual. It is the sort of love one can imagine between angels."

-C.S.Lewis

Quote of the Day

"A dog has no use for fancy cars or big homes or designer clothes. Status symbol means nothing to him. A waterlogged stick will do just fine. A dog judges others not by their color or creed or class but by who they are inside. A dog doesn't care if you are rich or poor, educated or illiterate, clever or dull. Give him your heart and he will give you his. It was really quite simple, and yet we humans, so much wiser and more sophisticated, have always had trouble figuring out what really counts and what does not. As I wrote that farewell column to Marley, I realized it was all right there in front of us, if only we opened our eyes. Sometimes it took a dog with bad breath, worse manners, and pure intentions to help us see."

Against Nuclear Overreactors - Nuclear Reactors Are Safer

William Saletan makes a more persuasive call than mine:

"
If Japan, the United States, or Europe retreats from nuclear power in the face of the current panic, the most likely alternative energy source is fossil fuel. And by any measure, fossil fuel is more dangerous. The sole fatal nuclear power accident of the last 40 years, Chernobyl, directly killed 31 people. By comparison, Switzerland's Paul Scherrer Institute calculates that from 1969 to 2000, more than 20,000 people died in severe accidents in the oil supply chain. More than 15,000 people died in severe accidents in the coal supply chain—11,000 in China alone. The rate of direct fatalities per unit of energy production is 18 times worse for oil than it is for nuclear power.
Even if you count all the deaths plausibly related to Chernobyl—9,000 to 33,000 over a 70-year period—that number is dwarfed by the death rate from burning fossil fuels. The OECD's 2008 Environmental Outlook calculates that fine-particle outdoor air pollution caused nearly 1 million premature deaths in the year 2000, and 30 percent of this was energy-related. You'd need 500 Chernobyls to match that level of annual carnage. But outside Chernobyl, we've had zero fatal nuclear power accidents.
That doesn't mean we can ignore what has happened in Japan. Precisely because nuclear accidents are so rare, we have to study them intensely. Each one tells us what to fix in the next generation of power plants. The most obvious mistake in Japan was parking the diesel generators in an area low enough to be flooded by a quake-driven tsunami. The batteries that backed up the generators weren't adequate, either. They lasted only eight hours, and power outage fallback plans at U.S. reactors are even shorter. Moreover, this is the second time an advanced nuclear facility has had to vent radioactive vapor (Three Mile Island was the first). Maybe it's time to require filtration systems that scrub the vapor before it's released.
Sen. Joe Lieberman of Connecticut says we should "put the brakes" on nuclear power plant construction until we figure out what went wrong in Japan. Rep. Ed Markey of Massachusetts wants a moratorium on new reactors in "seismically active areas" while we study the problem. That's fine. But let's not block construction indefinitely while we go on mindlessly pumping oil. Because nuclear energy, for all its risks, is safer."

The Grace of Doing Nothing vs Must We Do Nothing - Niebuhr on Humanitarian Intervention

Niebuhr's influence on the 44th is no secret; Niebuhr on humanitarian intervention - here (pdf):

All this does not prove, however, that we ought to apply the words Jesus, "Let him who is without sin cast the first stone," literally. If we do we will never be able to act. There will never by a wholly disinterested nation. Pure disinterestedness is an ideal which even individuals cannot fully achieve, and human groups are bound always to express themselves in lower ethical forms than individuals. It follows that no nation can ever be good enough to save another nation purely by the power of love. The relation of nations and of economic groups can never be brought into terms of pure love. Justice is probably the highest ideal toward which human groups can aspire. And justice, with its goal of adjustment of right to right, inevitably involves the assertion of right against right and interests against interest until some kind of harmony is achieved. If a measure of humility and of love does not enter this conflict of interest it will of course degenerate into violence. A rational society will be able to develop a measure of the kind of imagination which knows who to appreciate the virtues of an opponent's position and the weakness in one's own. But the ethical and spiritual note of love and repentance can do no more than qualify the social struggle in history. It will never abolish it.

I find it impossible to envisage a society of pure love as long as man remains man. His natural limitations of reason and imagination will prevent him, even should he achieve a purely disinterested motive, from fully envisaging the needs of his fellow men or from determining his actions upon the basis of their interests. Inevitably these limitations of individuals will achieve cumulative effect in the life and actions of national, racial and economic groups. It is possible to envisage a more ethical society than we now have. It is possible to believe that such a society will be achieved partly by evolutionary process and partly by catastrophe in which an old order, which offers a too stubborn resistance to new forces, is finally destroyed.
It is plausible also to interpret both the evolutionary and the catastrophic elements in history in religious terms and to see the counsels of God in them. But it is hardly plausible to expect divine intervention to introduce something into history which is irrelevant to anything we find in history now. We may envisage a society in which human cooperation is possible with a minimum amount of coercion at all—unless, of course, human beings become quite different from what they now are. We may hope for a society in which self-interest is qualified by rigorous self-analysis and a stronger social impulse, but we cannot imagine a society totally without the assertion of self-interest and therefore without the conflict of opposing interests.

To say all this is really to confess that the history of mankind is a personal tragedy; for the highest ideals which the individual may project are ideals which he can never realize in social and collective terms. If there is a law in our members which wars against the law that is in our minds as individuals, this is even more true when we think of society. Individuals set the goal for society but society itself must achieve the goals, and society is and will always remain sub- human. The goal which a sensitive individual sets for society must therefore always be something which is a little outside and beyond history. Love may qualify the social struggle of history but it will never abolish it, and those who make the attempt to bring society under the dominion of perfect love will die on the cross. And those who behold the cross are quire right in seeing it as a revelation of the divine, of what man ought to be cannot be, at least not so long as he is enmeshed in the processes of history."


Circa 2011, Operation Odyssey Dawn:

"
This is not an outcome that the United States or any of our partners sought. Even yesterday, the international community offered Muammar Qaddafi the opportunity to pursue an immediate cease-fire, one that stopped the violence against civilians and the advances of Qaddafi’s forces. But despite the hollow words of his government, he has ignored that opportunity. His attacks on his own people have continued. His forces have been on the move. And the danger faced by the people of Libya has grown.
I am deeply aware of the risks of any military action, no matter what limits we place on it. I want the American people to know that the use of force is not our first choice and it’s not a choice that I make lightly. But we cannot stand idly by when a tyrant tells his people that there will be no mercy, and his forces step up their assaults on cities like Benghazi and Misurata, where innocent men and women face brutality and death at the hands of their own government.
So we must be clear: Actions have consequences, and the writ of the international community must be enforced. That is the cause of this coalition."

Econophysics - Possible Early Warning Sign for Market Crashes

Bar-Yam’s findings, released Feb. 13 on arXiv, are part of an emerging research field known as econophysics. It applies to economics insights from the physical world, especially from systems in which networks of interacting units produce radical collective behaviors.
Heated water turning to gas is one such behavior, known technically as a phase transition. Another is snow gathering into an avalanche. Seen through an econophysicist’s eyes, a stock market panic is an avalanche, too.
Using a phase-transition model, Bar-Yam’s group analyzed patterns of movement in the stock market. At the beginning of the 2000s, co-movement was low. On any given day, about half the stocks were moving up or down. By 2008, shortly before the crash, co-movement was absolute. People were no longer making independent decisions, but copying others.
Fuhrer’s cautions were echoed by econophysicist Tobias Preis of the Swiss Federal Institute of Technology. “One should be very careful about generalization to predict future crises,” he said. “The most important point is to quantify this risk. That would be a huge step forward.”
If co-movement does prove to be a reliable early warning signal, it’s an open question how to make use of it. “That is one of the $64,000 questions,” said Fuhrer.

Heroic Dog Won't Leave His Injured Friend in Japan Debris

This is heart breaking...
"We are in Arahama area. Looks like there is a dog. There is a dog. He looks tired and dirty. He must have been caught in the tsunami. He looks very dirty. He has a collar. He must be someone's pet. He has a silver collar. He is shaking. He seems very afraid. Oh, there is another dog. I wonder if he is dead. Where? Right there.
"There is another dog right next to the one sitting down. He is not moving. I wonder. I wonder if he is alright. The dog is protecting him. Yes. He is protecting the dog. That is why he did not want us to approach them. He was trying to keep us at bay. I can't watch this. This is a very difficult to watch. Oh. Look. He is moving. He is alive. I am so happy to see that he is alive. Yes! Yes! He is alive. He looks to be weakened. We need to them to be rescued soon. We really want them rescued soon. Oh good. He's getting up. It is amazing how they survived the tremendous earthquake and tsunami. It's just amazing that they survived through this all."
