Paradigm shifts are rare and significant changes in the way humans view the world. They are major changes which are controversial when first proposed but eventually come to be accepted as a major advancement in scientific knowledge and understanding. Examples of paradigm shifts in past scientific world views are the revolutionary ideas that the earth is round not flat and that it rotates around the sun.

Now Reflect on a past paradigm by considering the following questions: How is it possible that people thought this way? What factors contributed to this mind-set? Are there still large numbers in the general population that think this way? Why are we/did we shifting to a different paradigm?
