Scientists have demonstrated that negative refraction can be achieved using atomic arrays -- without the need for artificially manufactured metamaterials. Scientists have long sought to control light ...

When Refraction AI was founded in 2019, its goal was to use robotics to bring down the cost of last-mile delivery. Over the past couple of years, the startup has worked directly with restaurants in ...

Please provide your email address to receive an email when new articles are posted on . In an earlier Lindstrom’s Perspective, I described cataract surgery and IOL implantation as a modern-day miracle ...

Recent experiments that demonstrate the negative refraction of light could bring a heated scientific debate to a close, and give negative-index materials a positive future Figure 1: Negative-index ...

Refractive errors are common eye issues that can cause blurry or distorted vision. Treatment usually involves wearing glasses or contact lenses or getting procedures ...

A property of a material that changes the speed of light, computed as the ratio of the speed of light in a vacuum to the speed of light through the material. When light travels at an angle between two ...

The Brix scale, derived from the refractive index of a solution at 20 degrees Celsius (68 Fahrenheit), is widely known. Originally, it was established by determining the weight percentage of sucrose ...
