This week, we follow advances in science and specifically in astronomy. Through brief biographies of some of the great figures in science, we examine the public influence and theological implications of their work. Finally, we have an opportunity to compare past understandings of the universe with our understanding of it today. 

This week's primary objectives are:

• Accurately and effectively communicate ideas, information, arguments, and messages to present material in a historical context.
• Investigate and evaluate historical information from global, social and ethical perspectives to guide decision making.
• Convey historical information by writing and speaking clearly and appropriately for different audiences and with an appreciation of diverse viewpoints.
• Demonstrate a chronological understanding of the different peoples, events, and cultures that have shaped human civilization.

Three biographies on Copernicus, Galileo, and Newton provide an overview of the life and times of these greats as well as their legacies. 

Tully's article on the size of the universe allows you to compare the understanding of those in the past to our knowledge today.
