Laser diodes are semiconductors that generate light and amplify it using repeated reflection or "optical feedback." Once the ...

Scattering takes place across the universe at large and miniscule scales. Billiard balls clank off each other in bars, the ...

They are important niches to the scientists who can now solve previously unsolvable problems, but they may not constitute ...

These are known as hypervelocity stars, with some moving faster than the escape velocity of the Milky Way of around 600 kilometers (373 miles) per second. There is another star that is almost as ...

The second law of thermodynamics underpins all of classical reality. It is the reason why it's easier to make things messy, why you can’t have perpetual motion, why you age, and maybe even why time ...

Lightweight, robust, radiation-resilient photovoltaics are critical technologies for many aerospace applications. OPV cells ...

Quantum technologies can be defined as technologies that, based on quantum mechanics, have capabilities that go beyond what ...
