How do we know the speed of light – and why does it have a speed limit at all? Leah Crane explores the history of one of the ...

Copper, platinum, aluminum, gold. Metals have been so important in human history that we’ve named historical epochs (the Bronze Age, the Iron Age) for their transformative power. These materials, with ...

Researchers built a computer that performs AI calculations at light speed in a single shot. The breakthrough can help AI ...

Physics can feel inscrutable to students; this lesson helps them understand a graphing problem by analyzing their own ...

The speed of light is a fundamental constant, approximately 299,792,458 meters per second. It's the same for all observers and hasn't changed measurably over billions of years. Nothing can travel ...

Scientists from the CMS collaboration at CERN have measured the speed of sound in the quark-gluon plasmas with record precision, a key step to understanding how matter behaved in the very early ...

Researchers have developed physics-based guidelines that will benefit host-guest intercalated materials research. By using only two guest properties and eight host-derived descriptors, they correctly ...

Princeton University professor John Hopfield has been awarded the 2024 Nobel Prize in physics "for foundational discoveries and inventions that enable machine learning with artificial neural networks.
