X-Rays _ GCSE Physics
X-Rays are part of the electromagnetic spectrum and have a wavelength of about the diameter of an atom. Because of this small wavelength they are able to penetrate healthy tissue but are absorbed by denser material like bone and metal....

Visual Processing and the Visual Cortex
We learned about the structure of the eye in the Anatomy and Physiology series. But how do we process visual information? Light hits the retina at the back of the eye, and then what happens? Well quite a lot, to be honest! We have to go...
