Thomas Kuhn, Revolutions, Paradigms, and Progress

The Problem of Progress The question I’m addressing today, is on Thomas Kuhn’s Structure of Scientific Revolutions. It was posed to me recently, in this form: “Is Kuhn right that we cannot speak of progress across scientific paradigms?” This paper will briefly summarize Kuhn’s own definition of progress both within and across paradigms, explore the implications of these definitions, and assess the conclusion Kuhn comes to at the end of Chapter XIII of The Structure of Scientific Revolutions.

Cosmos: Sagan vs Tyson

I have been thinking about this on-and-off, recently. What is the difference between the Sagan Cosmos, and the Tyson Cosmos? There are lots of fairly uncharitable things to say about both of these men, but if we were forced to provide an actual explanation, I think three things could be said: Era / Audience. The original Cosmos was released in 1980. Not since the early eighties, have I felt the same sense of optimism and yearning for the promise of the future.
