On Alien Intelligence

A quick but thought provoking interview with Michael Shermer, founder of the Skeptics Society.  Whether you believe there is alien intelligence in the universe or not, the interview delves into the thought experiments behind the belief and the nature of science itself.

One statement by Shermer really made me think:

… all science is a signal-to-noise problem.

This is the essence of science, I think.  All the experiments, theories and questions asked and performed by scientists boil down to discerning the signal (proof, fact, truth, what-have-you) from the noise (falsehoods, untruth, etc).  From this, you can derive a distinction between pseudoscience and true science.
