What happened next?

Over the next days of class, we continued to add precision to diagrams and then pursue questions that this inquiry had raised.

The questions were:

  • Do thirds and fourths actually matter?
    When light bounces off a surface, how does it behave? (Koosh, special angle or combination?)
  • Why are there crisp edges when light (without mirror) [shines] through tube?
  • What’s the difference between mirror and other surfaces (white v. black paper for instance)?
