Wealth and power have been our conventional measures of success. What definition will better sustain us now and how can we move into it?
Sucess should be analyzed not by competition but my refering to previous personal goals in life. When, in the future, we look into what we would hoped to achieve and "calculate" if, with the information we had at the time, could we do something different to achieve the goal or not. If not, the attempt is equally important. An viable attempt sort of speech in which there is no prove, at the time, that it would be impossible or ilogical to pursue that goal with that particular approach.

Celebrating the death of our enemy is returning hate for hate and "multiplies hate, adding deeper darkness"
I think the Nuremberg trial was a different thing as it wasn't Hitler himself. Even so, the great majority were condemned to death penalty and with Osama Bin Laden the American people wouldn't accept any other outcome of a trial. It isn't about the president popularity is about national security as people would flock to where Bin Laden would be imprisoned either to worship him or try to kill him. The argument that we can't attack leaders such as him because of the revenge of the terrorists is null. Wouldn't it happen anyway if he was condemned to death or even life in prison? Wouldn't they want revenge anyway, or worse, wouldn't they try to free him? So, the other alternative would be just let him continue to do what he was doing because the backlash MIGHT be too big? As for attacks in America or outside of it one have to consider that the majority of the attacks out of the US specifically targets american turists so they have an interest as well, maybe not in the Mumbai case but in many many others. Killing him and dumping in the ocean was a compromiss and a hard one at that. On one hand, not make it public the videos or photos or parade him across the world was the correct choice. On the other, they could alleged they respected the muslim traditions of burial within 24 hours of death. In addition I do believe in the official story in which he tried to go for his guns. Firstly, he always said he wouldn't be taken alive and secondly why would he want to be caught alive anyway? But, nevertheless, killing him was important as an example that justice is served. It was bad enough that he ran for 10 years, only empowering the wills of those who intend to do terrorism. As for the backlash, we can't make decisions based on that. I know it is easy for me to say but the backlash is coming, wether is to avenge Bin Laden, or because some cartoons or because we don't share the same religions. The point is, terrorists never needed the extra motivation to kill.

Will Osama bin Laden's death by the American military be a source of division amongst Western Nations?
As an european I can honestly say by the reactions of the people that surround me and by the media in my own country (Portugal), that we are closer to the America's policies now more than ever. Mr. Bush and the Iraq war left us with a big scar on that departament but Obama brought hope to the european nations (especially visable when he went to Germany) and war on terror was always something we could back america's policy on as in the afghan war.

In the end Bin Laden was a symbol and I dont think people were actually celebrating his death but rather a new hope of ultimately unreachable security and safety. I think we all can agree that we all much rather he hadn't did any of that and lived a long and happy life. However, having done what he did, he become a threat larger than his own life as a symbol, a leader, an uniter of many different dangerous people and organizations. Had he be captured and judged he would became a martyr. A judgement would be pointless as well because no judge in the world could ever let him go. Can you imagine Bin Laden going to a US court and left on bail? What would happen then? Revolts at the very least. So no good would came out of a court day in a pratical and pragmatic fashion. Celebrating Bin Laden's death is equivalent to celebrating Hilter's: it marks the end of an era of war.

Extinction of human being in past history of earth and Evolution theory
Hello, Scientists, as far as I can tell, already accept that evolution don't necessarily deny the existence of God. However, religious people not only want God to be accepted by the scientific community but as they see it: as the creator of all life as we know it and not by evolution. I agree with you, evolution might be a "tool" of God to create and develop but many religious people don't agree. As for scientists, the majority does not agree as well but can't actually deny it because there is no evidences otherwise. There is, however, evidences that the Earth is 4,6 billions years old. As far as extinctions go, humans were remarkingly close to it as a ice age nearly kill every human and narrow our numbers at the time to a few hundreds (hence the very similiar DNA we know share despite our "age" as species)

Are there any merits for political violence (terrorism)?
I believe in peaceful movement and intentions but with a violent levarage sort of speech. Let's examine two example: Tiananmen Square and my favourite "25 de Abril" my own country revolution for removing a dictatorship. Tiananmen Square can't be classify as a revolution as it didn't provided results. When facing a military presence, peaceful movement is useless at best, a massacre at the worst. "25 de Abril" on the other hand was a military movement with precise accuracy and planning, using radio as signal for movement with a significant show of force by surrounding the loyal regime forces quickly and overpowering them, making any resistance futile, pointless and suicidal. Hence, by showing force and not using it, it make a revolution without any bloodshed. As for guerrila type revolution it would depend on the targets: civilian or military.

Waterboarding: Justifiable or unacceptable?
Saying torture is helpful in a broader strategy and policy is like saying we can bring about world peace if we nuked the planet and bring about equality as well because we would all be equally dead. The ends do not justify the means. Having said that, in a particular situation as some have declared here like a family member of mine have been made hostage and someone won't disclosure that information, one could be emotional about it but the proper authorities could not and not endorse torture. That is also why we do not negotiate with terrorists: because we know, in the long term, it would be beneficial for the whole society, although it might seem the best option to safeguard someone's life. And waterboarding is another particularly stupid concept to me. The way the american govermnent played around with the concept and definition of torture to justify waterboarding as not torture is simply pathethic.

Burying charcoal to improve crop yield and offset CO2
Thanks for your answer. I can see how it may sound rather stupid and I apologize for that. As far as I can tell based on the articles you have provided, it basically is removing the volalite gases trough pyrolysis much like a normal combustion would but by maintaining a low level oxygen atmosphere you can provide a limited oxidation of carbon hence maintaining more carbon than a normal combustion would. But the formed gases is where I have most doubts. How do you control emissions of NOx and/or SOx as well as aromatic compounds? Thank you once again
