Do you use crowd wisdom to think? Be part of creating the first ever crowd sourced TED talk
Last year I wrote a couple of applications for android devices, mostely with the purpose of learning how to do so. In each application I added my email address and asked people to send feature request. The requests I got by mail, and through the comments in the market was realy essential for improving the applications. Some feature requests came from several different people, and others from fewer, and that provided a really good way to get an idea about what people used the applications for, in what way they used them, and what types of changes would make most impact for most users. Would never have been able to figure out all the unexpected ways people used the applications and how to provide the right functionallity without the help from the people that actually where using them.

Seems like Jesus became popular at the begining of the 19th century. http://ngrams.googlelabs.com/ngrams/graph?content=Jesus%2CChrist%2CChristian%2CGod&year_start=1500&year_end=2008&corpus=0&smoothing=3

Haha, couldn't resist commenting on this one. Your explanation is most certainly correct Christie. Look at this: http://ngrams.googlelabs.com/ngrams/graph?content=fuck%2Csuck&year_start=1700&year_end=2008&corpus=0&smoothing=3

How can we encourage mainstream media coverage of Israeli and Palestinian nonviolence leaders?
Share links to such stories through social media, blogs etc. Most news agencies probably use analytic tools to evaluate which stories that get attention, for example by counting the number of times a certain article is delivered to a webbrowser. Emediate user feedback is much easier today than ever, and if news agencies not are using extensive analytics on their articles already, I bet they will within a few years. By linking to such news and help bring the numbers up for articles that covers the situation in that light, the news agencies will realize that it is a kind of article that sells and thus more of it will be created.

What's your TED habit?
I mainly use TED in two way. First I almost allways watch the latest TED talk when I arrive home from work in the weekdays. Second I use TED videos and TED conversations in combination with other sites such as Wikipedia, academicearth, topdocumentary films, YouTube , etc. when I want to explore a topic that interests me. Here I use to search the archive and watch a few related talks in a row.

Space 2050: Are we prepared for meeting 'Alien' life?
Yeah I think I was a bit disapointed when I realized it too. :( Have watched the biosphere talk and it was really interesting. I would love if a project like that was underaken on the moon or mars during my lifetime. I can really see some usefullness in collonising other planets. If robotics are developed to the point where they can sustain factories that don't need human workers, we could move our nuclear powerplants there and beem the energy down to the earth.

Space 2050: Are we prepared for meeting 'Alien' life?
The sad thing when it comes to space travel is that the distances are enormous. If we find life in our own solar system, we will hopefully be able to examine it first hand. But anything other than very primitive life forms should not be expected. The closest star is more than four light years away, and with the speed mars mission travels at it would take thousands of years to reach there. As long as we don't discover something that radically changes how we understand the universe in terms of special relativity, we are almost certainly never going to be able to travel to any other solar system. I think our best hope would be to be able to comunicate with relatively close inteligent life through radio waves. But such commmunication would be very difficult as well as we would have to wait at least eight years to get an answer to our sent messages. And that is if there is life intelligent enough to build electronic equipment in the closest solar system. When it commes to life on other planets, I think I find the most interesting idea to be that we maybe could plant life on one or several of the planets in our solar system and generate life there. With the advances in bioengineering, maybe we can engineer really tough bacterias that survive on the surface of mars, eats rocks, and creates an atmosphere there.

Is gravity a result of mass or size?
This is the correct answer. The mass (or energy) is what determines how much space-time is bent. The gravitational pull is proportional to the curvature, but the curvature is determined by the amount of mass (energy).

Would you kill one person if you knew it would save millions?
In the case of Hitler and the holocaust I don't think we should attribute to much of what happened to Hitler. Don't missunderstand me. What Hitler did was terrible, but I think the main problem was the circumstances. People felt dissapointed by the outcome of the first world war, eugenics were popular, and there was the great depression. People were looking for a leader like Hitler to step forward, and I find it likely that if Hitler not had been born someone else would have taken the role instead. This is why I think that the most important thing often not is to find who is responsible for this or that, but to allways try to fight the circulation of stupid and dangerous ideas.
