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

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 ...

The speed of light isn’t just a number — it’s the foundation of reality. But new research into how light behaves across space ...

What would it really take to travel at or beyond the speed of light? In this video, we break down the hard physics Hollywood skips: why nothing with mass can reach light speed, how energy needs ...

Emmy Noether showed that fundamental physical laws are just a consequence of simple symmetries. A century later, her insights continue to shape physics. In the fall of 1915, the foundations of physics ...
