The findings give hope for a new type of light source for quantum computing and quantum communication. Intense research on carbon nanotubes has uncovered numerous intriguing properties ...

[Oneironaut] sent us another IR hack. This time it is a writeup on the best ways to create IR light sources from regular lights. Since normal flashlight bulbs emit a broad enough spectrum to ...

Lasers, LEDs and light sources are devices that create light. LEDs (light emitting diodes) convert an electrical current into light using spontaneous emission in optically active semiconductors.

Anshu explores his bedroom as his eyes become accustomed to the dark, noticing the different light sources from inside his room, his house and outside his house. Whilst watching this clip ...

For hundreds of a millions of years, the universe existed in the dark ages—an epoch when only primordial gasses existed. Then ...

This is because they block a larger amount of light. If the light source is close to the shadow, this also leads to a larger shadow. Some shadows, like the palm trees, change in size. This is ...

This flexibility allows buyers to diversify their energy sources and mitigate risks, which is something Lightsource bp is well-positioned to provide as we are active across 20 markets globally ...
