When you throw a ball in the air, the equations of classical physics will tell you exactly what path the ball will take as it ...

Invisible infrared waves are emitted by IR LEDs and detected by photodiodes to enable devices like remotes, automatic ...

Time already behaves strangely in modern physics. It can stretch, slow, and split depending on speed and gravity.

An international team has demonstrated a new method for producing the most intense light ...

A tiny silica bead, just 100 nanometers across, sits suspended in a vacuum and vibrates under the grip of laser light. Those ...

An international team of physicists has achieved a significant advance in laser science, demonstrating for the first time a ...

A leading physicist argues the brain may operate like a quantum system—and that enhancing it could create humans who perceive ...

When you throw a ball in the air, the equations of classical physics will tell you exactly what path the ball will take as it ...

Some quantum cryptographers want to find ways to keep messages secret even if the rules of quantum mechanics don’t hold. The ...

Few concepts in physics are as familiar, yet as enigmatic, as time. In Einstein's theory of relativity, time is not absolute: its passage depends on motion and gravity. But when combined with quantum ...
