hapter 2 What is Science? - All of the things that we currently know. - A process for gaining more knowledge. - use of Scientific Method theory – a testable explanation for the results of an experiment or observation hypothesis – an educated guess “Just a theory” is not appropriate in science. A theory is our best explanation based on the current data. - ex. gravity is a theory How to choose between competing theories? - Occam’s razor – the simpliest theory should be preferred What does science have to say about religion? - Nothing. Religious beliefs are not testable and cannot be examined by the scientific method. Example of a theory that was eventually replaced: Geocentric Cosmology - Based on observations of objects moving in the sky (Sun, Moon, stars), ancient Greeks theorized that the Earth is the center of the Universe and everything revolves around it. - Problems with this theory: some of the planets take funny paths across the sky with retrograde motion, where they appear to move backwards. -
