For the first time, scientists have demonstrated that negative refraction can be achieved using atomic arrays—without the need for artificially manufactured metamaterials.

For the first time, scientists have demonstrated that negative refraction can be achieved using atomic arrays -- without the need for artificially manufactured metamaterials.

The law of refraction first derived by Snellius and later introduced as the Huygens–Fermat principle 1, states that the incidence and refracted angles of a light wave at the interface of two ...

Isaac Newton is, as most will agree, the greatest physicist of all time. At the very least, he is the undisputed father of modern optics,­ or so we are told at school where our textbooks abound with ...

In this extract from the new book Beautiful Experiments: An Illustrated History of Experimental Science, science writer Philip Ball explains how Isaac Newton transformed our understanding of light.
