Welcome to Radio Ecoshock. This week's program is about schizophrenia: the state of hoping the system will crash before it kills the planet, while counting on all the usual creature comforts of home, jobs, and a well-stocked supermarket. Yes, I know the Western world is hanging in suspension. We're waiting for the shopping to resume, for the economy to rebound, for the good life to return. Most politicians and the mainstream press promise that it will all go back to the normal process of chewing up and spitting out the last of the planet's goodness. Meanwhile we go to movies like 2012, slurping up scenes of the destruction of everything. Part of our secret selves hopes it all goes down in flames, or floods. Even while we worry about our children having a decent life. You see how it goes? I know you are worried about the economy. Maybe even your own job or home is at risk. Despite the propaganda, we'd be crazy not to worry about it. I've been told the general formula for every speech and radio program goes as follows: we paint the grim picture, but always, always end on a positive note. Give humans solutions, or they'll just go numb and do nothing. Sorry. This week we violate the rules. Lately Radio Ecoshock has run a series about greening our cities. A couple of listeners have written back, saying cities can never be sustainable, as Derrick Jensen says. Have I fallen into the camp of false good cheer? We'll start out with one of the most promising solutions I've heard about lately - a dream of new economics coming from a British government advisor, Professor Tim Jackson. He's got a new book out "Prosperity Without Growth". Then we'll head into more pessimistic territory with Dave Cohen, an analyst for ASPO, the Association for the Study of Peak Oil and Gas. Having written the American Empire is now obviously in decline, Cohen asks "Now What?" We talk more about the economic crisis, Wall Street bull (and bears) - and the energy crisis. Along with James Howard Kuntsler, and our recent guest Richard Heinberg, Cohen says normal consumption is never coming back. We might as well prepare ourselves for very hard times. We'll trash smug Canadians a bit, since real estate north of the border is just as stupidly over-leveraged as the American market. Then we'll notice Australia melting in the heat, while they push even more coal. A big Canadian company has just bought into the dirty Aussie coal market. Aren't we proud? In the end, I wonder, is hope just getting in the way of dealing with the limits of reality? This show is peppered with audio clips, including shorties from Max Keiser, Jeff Buckley's song "The Sky Is A Landfill", Bob Holman's "We Are the Dinosaur", and of course ending with the show title "Dinosaurs Will Die" from NOFX. We open with "Times Is Hard" by Loudon Wainwright III. READ MORE

This week on Living Planet: the German chancellor announces plans to attend the climate conference in Copenhagen, Ecuador calls on the international community to pay it not to drill for oil, and bridging the social and ecological divide between the German majority and Turkish minority. Merkel announces plans to attend Copenhagen German Chancellor Angela Merkel will be joining her French and British counterparts at the global climate summit in Copenhagen. Many have applauded the move, but some environmentalists are skeptical.The announcement comes only days after leaders at the Asian Pacific Economic Cooperation summit in Singapore said they did not expect a major breakthrough at the talks. According to Merkels spokesman, these low expectations are partly why the chancellor has decided to attend. A former environment minister, she wants to play an active role in ensuring that the participating countries reach more ambitious agreements. Merkel isn't the first European leader to announce plans to personally travel to the Danish capital. But as Europe's largest economy and one of the greenest countries on the planet, Germany is certain to play a major role in the negotiations. However, some politicians and experts are skeptical about the chancellor's plans. Report: Eva WutkeEcuador wants money not to drill Industrialized nations are expected to pay out hundreds of billions of dollars over the next 40 years to help their developing counterparts combat the effects of climate change. Ecuador has proposed one way that money could be put to use.The small South American nation of Ecuador is one of the planet's 17 megadiverse countries, a group of nations that harbor the majority of the Earth's species. It's also one of world's poorest nations, with 40 percent of citizens living below the poverty line. All this despite the massive stores of oil tucked away beneath the ground. Since the 1970s, the government in Quito has allowed companies to pump oil out of the country, with little thought to the effects this would have on the environment. Ecuador has profited little from its natural resources and it's now realizing the environmental mistakes that have been made. Which is why they have come up with an offer to take with them to Copenhagen this December. They want money from the international community to invest in infrastructure and biotechnology, and in return they'll leave half of the available oil in the ground. It's one alternative, and if it works, other developing nations home to both immense biodiversity and oil like Venezuela and Nigeria might follow suit. Report: Thomas Nachtigall/Patricio Luna/Clare Atkinson Berlin eco-center helps migrants integrate while saving the planet Most migrants leave there homes in search of someplace better with more resources. Their ecological knowledge is often limited and most governments have no way to address that.In Germany, Turks make up the largest immigrant group. They were invited here following the Second World War as guest workers, and many of them never left. Many have also never fully integrated into German society, and blame for that has been passed around for decades. Turgut Altug is trying to change that while also building up ecological knowledge among immigrants. In the Berlin neighborhood of Kreuzberg he has founded a German-Turkish environment center to help with that mission the first of its kind in Germany. Report: Richard Fuchs

Avec Giuseppe Longo, dans le cadre du cycle : Journée d'études L'anneau des disciplines. Enregistré le 16-11-2009 à 11:45. 1. (point de départ de la collaboration et du livre avec Francis Bailly) Les fondements des mathématiques et de la physique : -- partagent les mêmes principes de construction conceptuelle, -- diffèrent dans les principes de preuve. En mathématiques, l'incomplétude gödelienne les départage : les principes de preuve sont incomplets par rapports aux principes de construction. Dès qu'une théorie contient l'arithmétique, un principe de construction (le bon ordre) n'est pas saisi par l'induction. En physique, la construction d'objectivité se fait dans l'interaction, entre la préparation de l'expérience (jusqu'à la production du quanton) et la proposition de principes à expliciter. L'intelligibilité est dans le jeu permanent de ces deux aspects de la pratique scientifique, mathématique et physique, principes de preuve et principes de construction. 2. Qu'est-ce que la complexité biologique ? Complexité objective versus complexité morphologique (phénotypique). Approches mathématiques de l'évolution darwinienne à la Gould, par rapport aux deux notions de complexité. Références bibliographiques : F. Bailly et G. Longo, Mathématiques et sciences de la nature. La singularité physique du vivant, Hermann, Paris, 2006. F. Bailly et G. Longo, Biological Organization and Anti-Entropy , J. Biological Systems, 17/1 (2009), 63--96.

Avec Hervé Le Guyader, dans le cadre du cycle : Journée d'études L'anneau des disciplines. Enregistré le 16-11-2009 à 10:30. Très souvent, les physiciens et mathématiciens qui se penchent sur la biologie arrivent avec des outils tout prêts qu'ils souhaitent appliquer à une nouvelle discipline. Dans la plupart des cas, cela ne fonctionne pas car les problématiques des biologistes ne sont pas intégrées. Il est clair que Francis Bailly n'appartenait pas à cette population : bien que féru de mathématiques et de physique, il voulait continuellement interroger le vivant afin d'en découvrir ses spécificités. Une lecture de l'ouvrage qu'il a publié avec Giuseppe Longo (Mathématiques et sciences de la nature, la singularité physique du vivant, Hermann, 2006) guidera notre exposé qui reprendra certains points comme ceux de structure et d'auto-référence partielle.
