The Study of Optics and Photochemical Effects a Historical Perspective

2 The Study of Optics and Photochemical Effects a Historical Perspective 

Historical perspectives are very important in a course of natural science. One becomes aware of facts rarely presented in a general history course. How was a discovery made What was the purpose of a specific experiment What was the researcher trying to achieve in the general scientific context of his time Trends can be uncovered, which lead from one discovery to the next. We will see then that science is not a gathering of two-dimensional information but, rather, a dynamic human drama in a four-dimensional space.
