Knowledge: The Sciences

A review of what we know and how we came to know it. From the study of Cosmology comes the knowledge of the unimaginably large. From Quantum Physics comes the unbelievable from the world of the unimaginably small. From recent advances in the life sciences comes a new understanding of us as animals in a world of animals. From the study of evolution comes the story of life. It tells us who we are and how we got to be us. And finally the science that isn't; claims and promises without any supporting evidence; from Deepak Chopra to sleeping on magnets, from megavitamins to "organic" foods. What is the truth? And how do we know it?
