Freeman Dyson of the Institute for Advanced Study in Princeton talks with EconTalk host Russ Roberts about science, his career, and the future. Dyson argues for the importance of what he calls heresy—challenging the scientific dogmas of the day. Dyson argues that our knowledge of climate science is incomplete and that too many scientists treat it as if it were totally understood. He reflects on his childhood and earlier work, particularly in the area of space travel. And he says that biology is the science today with the most exciting developments.

Science Weekly: End of the World News
We talk to the BBC’s David Shukman about reporting climate change and the BP oil spill. Plus, the results of the Guardian’s hack day, a study on mobile phone masts and cancer, and the pitfalls of patenting genes.
A gaggle of geeks recently invaded the Guardian’s London headquarters for a hack day. Their leader, Jeremy Keith, reveals the results of two days of brainstorming.

Stewart Brand: Rethinking Green — The Long Now
This talk was given at Cowell Theatre in Fort Mason Center in San Francisco, California on Friday October 9, 02009.
Brand built his case for rethinking environmental goals and methods on two major changes going on in the world. The one that most people still don’t take into consideration is that power is shifting to the developing world, where 5 out of 6 people live, where the bulk of humanity is getting out of poverty by moving to cities and creating their own jobs and communities (slums, for now).
The second dominant global fact is climate change. Brand emphasized that climate is a severely nonlinear system packed with tipping points and positive feedbacks such as the unpredicted rapid melting of Arctic ice.
Global warming has to be slowed by reducing the emission of greenhouse gases from combustion, but cities require dependable baseload electricity, and so far the only carbon-free sources are hydroelectric dams and nuclear power. Brand contrasted nuclear with coal-burning by comparing what happens with their waste products.
Moving to genetically engineered food crops, Brand noted that they are a tremendous success story in agriculture, with Green benefits such as no-till farming, lowered pesticide use, and more land freed up to be wild. The developing world is taking the lead with the technology, designing crops to deal with the specialized problems of tropical agriculture. Meanwhile the new field of synthetic biology is bringing a generation of Green biotech hackers into existence.

Cities, Design and Climate Change
With cities contributing upwards of 75 per cent of global carbon emissions, urban design is increasingly important when planning for climate change. This discussion examines the creative urban design solutions coming out of the world’s cities. Saskia Sassen is Robert S Lynd Professor of Sociology at Columbia University. Richard Sennett is professor of sociology at LSE and NYU. Jonathon Porritt is the chair of the sustainable development commission and founder and director of Forum for the Future.
