Massive ships seem too heavy to float, yet the answer lies in a principle discovered in ancient Greece. This explains how displacement, density, and hull design generate enough buoyancy to support ...

Abstract: Small uncrewed autonmous vehicles (UAVs) equipped with deep learning models are increasingly used to detect small objects both on the ground and in aerial environments. Since small objects ...

When containers fall overboard, some sink fast, but others can float for months as barely visible hazards just under the surface. This breaks down the real buoyancy physics, how cargo changes ...
