Special Relativity

I wrote the first chapter of a text book on Special Relativity. I think I might call the text "Special Relativity in your bones" because the goal will be not so much to learn about it academically as to have it become a part of the way you think about the world. By the end of the textbook you should be able to hear that a bullet moves at x miles per hour and calculate in your head the length contraction and time dilation associated with that bullet. And you should know how to mentally rotate time into space and vice verse as you think hop from one special referrence frame to another. You should be able to derive the whole theory from the premise that the speed of light is a law of physics.

It assumes high school math and has been fun to write. It's modeled on the Saxon math textbook series. Anyway, since beginning I have found out that writing the thing is going to be a bit of a recursive process. If you want to read through the first chapter let me know. I'd love feedback.

I'll add a comment to this post when I get to a finishing point on any given unit. Currently finishing such an incremental part of the book consists of the following tasks:

• I've written the explanatory section
• I've written up the problems (20 to 30)
  
• I've written up the solutions
• I've found and included an appropriate quote
  
• I have the content outlined for the next 5 units
• I've taken into account any feedback that I've received on previous units.
