| Theory for metamaterials that act as an analog computer Posted: 09 Jan 2014 11:37 AM PST A new study shows that metamaterials can be designed to do "photonic calculus" as a light wave goes through them. A light wave, when described in terms of space and time, has a profile that can be thought of as a curve on a Cartesian plane. This theoretical material can perform a specific mathematical operation on that wave's profile, such as finding its derivative, as the light wave passes through the material.  |
| What would make you more likely to read this story? Posted: 08 Jan 2014 08:26 AM PST New research has found that question headlines are significantly more effective than declarative headlines in generating readership. The study looked at the impact of question headlines in computer-mediated communications.  |
