Three thought experiments involving “demons” have haunted physics for centuries. What should we make of them today?

For nearly two centuries, textbooks blamed icy spills on pressure and friction, but new simulations tell another story. The ...

New research using Cassini data suggests Titan may not have a global ocean, but small warm water pockets hidden deep in its ...

Classical Mechanics:** Newton’s second law (F = ma) explains the relationship between force, mass, and acceleration. The law of universal gravitation describes the motion of heavenly bodies based on ...

On Antarctic ice, movement itself becomes a survival test, especially for an animal that spends months walking far inland to ...

Despite how advanced robots have become, getting them to feel the way humans do is an incredibly complex challenge.

Understand rotational motion in a clear, intuitive way with a lesson designed to stick with you forever. This video breaks ...

Singing sand dunes create a deep booming sound during avalanches due to synchronized sand grain vibrations under hot, dry ...

The text is now best known for introducing “Pascal’s Law” or “Principle,” that any change of pressure in an enclosed incompressible fluid (like water) is transmitted equally to all points within the ...

Unlike YR4, finding earlier observations of 3I/ATLAS to model where it might have come from was easier said than done. During its July 1, 2025 detection, the interstellar object happened to be moving ...

Quantum communication saw major progress, including longer-distance demonstrations and systems that operate closer to ...

This is no normal mini PC, as the price highlights, but the power and expansion options offer serious potential ...
