February 20 LSD ?A series of fun videos about LSD : LSD testing on British troops A pretty girl on LSD Learn about ecology in the sixties and LSD at the same time ... this is very scary - the environment pollution part I mean :) : LSD vs Ecology January 08 A pale blue dotFrom Carl Sagan's lecture at Cornell university, commenting on the image below : "We succeeded in taking that picture [from deep space], and, if you look at it, you see a dot. That's here. That's home. That's us. On it, everyone you ever heard of, every human being who ever lived, lived out their lives. The aggregate of all our joys and sufferings, thousands of confident religions, ideologies and economic doctrines, every hunter and forager, every hero and coward, every creator and destroyer of civilizations, every king and peasant, every young couple in love, every hopeful child, every mother and father, every inventor and explorer, every teacher of morals, every corrupt politician, every superstar, every supreme leader, every saint and sinner in the history of our species, lived there on a mote of dust, suspended in a sunbeam. The earth is a very small stage in a vast cosmic arena. Think of the rivers of blood spilled by all those generals and emperors so that in glory and in triumph they could become the momentary masters of a fraction of a dot. Think of the endless cruelties visited by the inhabitants of one corner of the dot on scarcely distinguishable inhabitants of some other corner of the dot. How frequent their misunderstandings, how eager they are to kill one another, how fervent their hatreds. Our posturings, our imagined self-importance, the delusion that we have some privileged position in the universe, are challenged by this point of pale light. Our planet is a lonely speck in the great enveloping cosmic dark. In our obscurity -- in all this vastness -- there is no hint that help will come from elsewhere to save us from ourselves. It is up to us. It's been said that astronomy is a humbling, and I might add, a character-building experience. To my mind, there is perhaps no better demonstration of the folly of human conceits than this distant image of our tiny world. To me, it underscores our responsibility to deal more kindly and compassionately with one another and to preserve and cherish that pale blue dot, the only home we've ever known."

"I know this was a miracle," 21-year-old housewife Patricia Goncalves Pereira told Globo TV. "Now I just want to extract the bullets and live my life." Pereira was shot Friday in the small city of Monte Claros, about 900 kilometers (560 miles) north of Sao Paulo, after quarreling with her former husband, who was reportedly upset because she refused to get back together with him. She was also shot once in the hand. Doctors could not explain why the .32-caliber bullets did not penetrate Pereira's skull and didn't even need to be extracted immediately. "I can't explain how something like this happened," surgeon Adriano Teixeira said, adding that the bullets were lodged under the woman's scalp. The ex-husband was still at large.

October 07 Multiverse or Universe ?What are the theoretical arguments for a Multiverse ? First check out : http://en.wikipedia.org/wiki/Multiverse_%28science%29 and a very nice (but more complicated) article by Max Tegmark, a famous and respected cosmologist. http://arxiv.org/abs/astro-ph/0302131 check out Max's fun website Potential energy and car crash.This is one of the most impressive car safety ad I have ever seen. What is the equivalent potential energy of the kinetic energy involved in a car crash ? The answer is in this short movie : http://tupearl.net/wp/upload/RF2006_504242_684VFX.mov Thanks to my good friend Tarlan for this one !
