This article explains, succinctly, what every introductory science class teaches and tests about the history of light. From Einstein’s simple theories to smart phones, this is a way to understand the theories and equations in narrative form. While we may be good teachers of math and concepts- we may be glossing over big ideas. Big ideas about how politics, personal relationships, and political events shaped the evolution of a scientific discovery. For those of us accustomed to a textbook explanation of history- this is a refreshing read about everything else the textbook leaves out.
