The speed of light is one of the most fundamental constants in physics, yet it has never been directly measured in one ...

Abstract: The complexity of data and limited model generalization significantly hinder prediction accuracy. A physics-informed long short-term memory model with adaptive weight assignment (PILSTM-AWA) ...

Step inside the strange world of a superfluid, a liquid that can flow endlessly without friction, defying the common-sense ...

More than 200 years ago, Count Rumford showed that heat isn’t a mysterious substance but something you can generate endlessly ...

Abstract: In this article, we introduce the notion of safe predefined-time stability and address an optimal safe predefined-time stabilization problem. In particular, safe predefined-time stability ...

"Ultimately, this work may help scientists better predict the impact of space weather across the solar system on longer ...

When the plasma physics community gathers for its biggest annual event, the Princeton Plasma Physics Laboratory (PPPL) shows up in force. This year's ...

Pulsars are some of the most reliable metronomes in the universe, and scientists are now using their flickering radio beams to keep time across the galaxy and sharpen the search for intelligent life.

Intuitively, we know what time is, but try to explain it, and we end up tying our minds in knots. When you purchase through links on our site, we may earn an affiliate commission. Here’s how it works.
