Scientists have made a satisfying and intriguing physics discovery some 16 years after it was first predicted to be a possibility: a quasiparticle (a group of particles behaving as one) that only has ...

Time’s passage is non-negotiable. Its flow marks the progress of our lives, moving clearly in one direction. It is, by nature, asymmetrical. In this way, we perceive it to move like an arrow, ...

Time feels like the most basic feature of reality. Seconds tick, days pass and everything from planetary motion to human memory seems to unfold along ...

For the first time, scientists have observed a collection of particles, also known as a quasiparticle, that's massless when moving one direction but has mass in the other direction. The quasiparticle, ...

This is where Emmy Noether, a groundbreaking German mathematician, comes into the picture. She found a breathtakingly simple ...
