In this one, on competition in science, he talks about public spending on science. He also notes some differences between the production of art and the production of science that could be interesting for those of you who are into the intellectual property rights issue. At the end he touches on what economists would call "intensive vs. extensive growth", and notes that innovation and science is necessary for extensive growth. Barry Eichengreen - in his book on the post-war European economy - stressed that the reason for the economic slow-down in Europe after their initial post-war growth miracles was that they did not have institutions that could foster extensive growth and innovation in the way that the U.S. did.
In this one he talks about science funding as stimulus. I of course agree with him, but I would make distintions between long-run and short-run growth here. He's talking about long-run growth and of course that's not the only thing we need to be thinking about right now. Science funding didn't do badly in ARRA but it was ridiculously lop-sided. The National Institutes of Health got a lot of the research funding, continuing a trend in NIH funding started by the Bush administration. I think a greater emphasis on NSF funding would have made more sense.
Also - Tyson has something in common with Keynes. They're both huge Newton fans.
