For the first time, physicists have watched a beam of positronium, a short‑lived atom made of an electron and its antimatter ...

Researchers used consumer-grade 3D printers to create sub-$1 optical lenses that enable super-resolution nanoscale biological ...

Researchers have shown that consumer-grade 3D printers and low-cost materials can be used to produce multi-element optical ...

Scientists have unveiled a new way to capture ultra-sharp optical images without lenses or painstaking alignment. The ...

For "Laser wavelength", the colors in the gradient and the dot does not match. For both "Laser wavelength" and "Grating line density", the range of the slider UI is not clear.

Optical dispersion occurs when the refractive index of a material changes with the wavelength of incoming light. This variation causes different colors to move at different speeds in transparent media ...

Entrepreneurs who build successful businesses often possess a unique ability to see what others don't—the critical bottlenecks hiding in plain sight that create frustration, inefficiency, and lost ...

Democrats have a problem: too many problems. Identifying the problems is not one of those problems. “Democrats have a trust problem,” suggests Representative Jason Crow of Colorado. “Democrats have a ...

Complex organizational problems and chaos are silent killers of productivity and innovation. In today’s fractured work environment, they are more prevalent than ever. Political transitions, ...
