chapter 2 of James Burke's  The Day the Universe Changed,  "In the Light of the Above", 

Watch Tom Wujec's 10 minute demonstration of the astrolabe. Here is a link 

This is the video introduces the idea of networks as a way of distributing information (about 55 minutes) : 

What does it mean to learn something? And has it changed over time? Some people say that technology changes the way we learn. Is this true? Just as importantly, does it change what we learn and why we learn? Burke outlines historic changes in learning and how these impacted the world in very big ways. Are the changes we see today, if any, just as big? Pay special attention to Wujec's comments on what context is required to tell the time with the astrolabe. What about networks as a way of teaching? We will see this issue of Context come up over and over again in the course when it comes to how we perceive information. 

All assignments are due at 11:59 in the morning.
