In this video, we derive the catenary curve using physics and calculus, explaining how a hanging cable reaches equilibrium under gravity. Step-by-step reasoning connects forces, differential equations ...

The accelerating expansion of the universe is usually explained by an invisible force known as dark energy. But a new study ...

Researchers adapt a novel force measurement technique to uncover the previously unidentified physics at play at the thin air-film gap between water droplets and superhydrophobic surfaces. Microscopic ...

I've been trying to explain quantum physics, forces, relativity, and space-time to my kid and we had a question that I'm finding difficult to find a solid answer to. Background you can skip if you ...
