Class Reflection for Lecture 04

Please create a post in this discussion reflecting on today's class.  Reflections are meant to be short and sweet – one paragraph (at least 50 words) – and should not take you long to write.  In your reflection you should address what was covered in class from one of three perspectives:  a practical take away for your work or career, an important unanswered question, or an interesting connection or insight.  See the Class Reflection Grading Rubric for details about how posts will be graded.
