(Latinized as Alhazen), inKitab al-manazir(c.1038; “Optics”), correctly attributed vision to the passive reception of light rays reflected from objects rather than an active emanation of light rays from the eyes. He also studied the mathematical properties of the reflection of light from ...

This type of pattern is similar to those reported for liquid crystal samples subjected to intense light rays [23]. The morphology of the ring pattern and the exhibited dynamics are different from those observed experimentally in the dye-doped nematic liquid crystal sample (see Figure 3 and ...
