The Titanic’s sinking was not just about damage, but about how buoyancy and stability shifted after the collision. This video examines the physics behind her loss, explores alternative outcomes, and ...

Ah, the stately hot air balloon. Not really useful for all that much except for having a grand old time floating around the skies, it's still a marvel of simple physics. Fill a giant balloon with air.

Submarines operate under very different rules than surface ships, especially when it comes to buoyancy and stability. This video explains why they float so low on the surface, how ballast and weight ...
