jan 1, 1609 - Galileo creates his own telescope (OS)

Description:

This assists in proving the heliocentric model is correct. This telescope was one of the most accurate until Newton's telescope. This event fits the AP Euro theme of Objective Knowledge and Subjective Visions because this time period was all about the increase in knowledge that spread across Europe during this time. It is all about the way people think things should be done and the knowledge that led people to those conclusions.
