Submission + - Does all of science really move in "paradigm shifts"? (

ATKeiper writes: Thomas Kuhn's landmark book The Structure of Scientific Revolutions just turned fifty years old. In that book, Kuhn coined the expression 'paradigm shift' to describe revolutionary changes in scientific fields — such as the replacement of the geocentric understanding of the universe with the heliocentric model of the solar system. The book was hotly debated for claiming that different scientific paradigms were 'incommensurable,' which implied (for example) that Newton was no more right about gravity than Aristotle. A new essay in The New Atlantis revisits the controversy and asks whether the fact that Kuhn based his argument almost exclusively on physics means that it does not apply as well to major developments in biology or, for that matter, to the social sciences.

Submission + - Property Rights in Space?

ATKeiper writes: A spate of companies has announced plans in the last couple of years to undertake private development of space. There are asteroid-mining proposals backed by Larry Page and Eric Schmidt, various moon-mining proposals, and, announced just this month, a proposed moon-tourism venture. But all of these — especially the efforts to mine resources in space — are hampered by the fact that existing treaties, like the Outer Space Treaty, seem to prohibit private ownership of space resources. A new essay in The New Atlantis revisits the debates about property rights in space and examines a proposal that could resolve the stickiest treaty problems and make it possible to stake claims in space.

I have a theory that it's impossible to prove anything, but I can't prove it.
