Opticks : $b or, A treatise of the reflections, refractions, inflections and colours of light

"Opticks: or, A Treatise of the Reflections, Refractions, Inflections and Colours of Light" by Isaac Newton is an early 1700s science book that carefully looks at light and what it does. It shows what happens when light bounces (reflection) or bends (refraction). The book sets up the rules for how we study light today. Instead of just guessing, the book uses experiments and clear thinking to explain things. It starts by laying out the basics, like what light rays are and how they act. It also points to experiments that will help explain these ideas. This shows how important accuracy and proof were to science at that time, making the book a key moment in the history of how we understand physics.
