Consider a case in which we want to collect data for the purpose of choosing a curve that will accurately predict the angle of refraction of a beam of light passing through a glass plate.
In the case above, we want to predict the angle of refraction (i.e.
That something is seriously wrong should immediately be apparent from the fact that the incident ray enters the prism at one of its vertices, and that an isosceles triangle has one base angle equated with the angle of incidence, and the other with the angle of refraction. Many other features of the diagram remain wholly unexplained, and what is going on only becomes clear if one consults the (acknowledged) source of Gaukroger's account, W.R.
