2/18/13: How do you determine what is "significant" in history?

 You determine what is "significant" in history by looking at how an event made an impact on the way the world is today. It is helpful to ask questions such as "What would the world be like if this event wouldn't have happened?" or "How would history have been affected if this event had been altered?" Something that is "significant" can be determined its lasting impacts on the way the world developed (i.e. The Neolithic revolution is significant because it allows large groups of people to live together and civilizations to develop).
