The Seeing Blind

The Seeing BlindAn article in this month’s Current Biology magazine has Justin Marshall from the University of Queensland, Australia, describing how stomatopod crustaceans can see circularly polarized light. While the human eye has three types of “color” photoreceptors, they have twelve types of visual receptor cells. A human being perceives light as color (the length of the wave) and brightness. Then there are bees, which perceive linearly polarized light, and as such, see things that we cannot. Moreover, the stomatopod crustaceans perceive circularly polarized light, and see other things altogether.

This is a good example of how limited we are in our perception of the world around us. We cannot perceive a characteristic like polarization, and we don’t know what else is around us that we cannot see. Such an example is one of many that supports what The Book of Zohar says: that there is a World of Infinity around us, and we only perceive as much of it as our sensory organs allow us to.
