Curiosities of Light and Sight

The author adapts a series of illustrated lecture essays that survey physical and physiological aspects of light and vision. Beginning with theories of light transmission and the nature of the eye, the text examines colour perception and experimental methods for producing and mixing colours, common optical defects such as astigmatism and multiple imaging, and a range of perceptual illusions and subjective effects including after-images and transient colour borders. Practical demonstrations and detailed diagrams accompany discussions of apparatus and experiments, inviting both professional and amateur investigators to explore optical curiosities and the foundations of visual sensation.
