ABSTRACT
Over 20 years ago the astronomer Carl Sagan observed that:
Science is more than a body of knowledge. It is a way of thinking; a way of skeptically interrogating the universe with a fine understanding of human fallibility. If we are not able to ask skeptical questions, to interrogate those who tell us that something is true, to be skeptical of those in authority, then, we are up for grabs for the next charlatan . . . . who comes rambling along. 1
