How do STEEL ships FLOAT⁉️⛴️

Neil deGrasse Tyson breaks down the history of steel ships and how science explains how it floats.

Boats are super fascinating, aren't they? Let me break it down for you in a fun and easy-to-understand way.

Boats work based on the principle of buoyancy. When a boat is placed in water, it pushes aside an amount of water equal to its weight. This displacement of water creates an upward force called buoyant force, which helps the boat float.

The shape and design of the boat also play a crucial role. Most boats have a hull, which is the part that comes into contact with the water. The hull is usually curved or V-shaped, allowing the boat to glide through the water smoothly. This shape helps reduce drag, which is the resistance encountered when moving through water.

To move forward, boats use different methods of propulsion. Some boats are powered by oars, where rowers use their strength to push against the water, propelling the boat forward. Others use engines, which can be powered by gasoline, diesel, or even electricity. The engine drives a propeller, which pushes water backward, generating a forward force that moves the boat.

Sailing boats, on the other hand, use the power of the wind. They have a large sail attached to a mast, which catches the wind and propels the boat forward. By adjusting the angle of the sail and controlling the rudder, sailors can navigate and steer the boat in different directions.

Boats also have other important components like the keel, which helps provide stability and prevents the boat from tipping over. Some boats have ballast tanks that can be filled with water to increase stability. And let's not forget about all the cool gadgets and instruments like GPS, radar, and navigation systems that help boaters navigate and stay safe on the water.

So, that's a simplified explanation of how boats work. They're a combination of clever design, physics, and human ingenuity.

Oh I thought they would sink when they go to the middle of the ocean and some ships I thought I would survive

This is too easy to understand... like looking at a car and seeing how it works by going through with your mind. what goes where and where the fire ignites...I would rather discuss with neil about something that is important..science and how does it work with us humans as a species and i am talking about more advanced science
