In summary, the conversation discusses the possibility of humans leaping from water like dolphins and the factors involved, such as buoyancy and velocity. The physics and formula behind this action are also mentioned, and references to xkcd and a video of a human performing a dolphin-like move are shared. The conversation concludes that while it is possible for humans to do so, they are not very fast swimmers without assistance.

Particularly how can a human leap from the water like a dolphin.
I'm guessing buoyancy and velocity are the main factors involved here, like a water polo ball pushed under will spring out no problem.
Or a whale given enough velocity.
A dolphin can dive deeper and quicker than humans and therefore swim up faster, but there has to be a point at which a human can do it, with the aid of flippers and buoyancy aids perhaps?
But it's the physics, the formula that would give me the specifics that I'm after.
Someone must have thought of this before, anyone?

It is possible, but without active help humans are just not very fast swimmers.
xkcd explored that idea, including various references.

Very cool :biggrin: From mfb's link:

That move he made before jumping was the closest thing to a fish that I have ever seen from a human. :oldeek::oldeek:
 

1. How do dolphins swim so effortlessly?

Dolphins have evolved to have streamlined bodies, powerful tail flukes, and flexible flippers that allow them to swim smoothly and efficiently through the water. They also have a layer of blubber that helps with buoyancy and insulation.

2. Can humans swim like dolphins?

While humans cannot swim exactly like dolphins, we can learn certain techniques and adapt our bodies to swim more efficiently. For example, using a monofin or dolphin kick can mimic the powerful propulsion of a dolphin's tail flukes.

3. What is the dolphin kick?

The dolphin kick is a specific swimming technique that mimics the movement of a dolphin's tail flukes. It involves keeping the legs together and undulating them up and down in a fluid motion, similar to a mermaid or dolphin.

4. Can practicing dolphin kick improve swimming abilities?

Yes, practicing the dolphin kick can improve swimming abilities in terms of speed and efficiency. It can also help strengthen the core and leg muscles, improving overall swimming technique.

5. Is it safe for humans to swim like dolphins?

Swimming like dolphins can be safe as long as proper precautions are taken. It is important to learn proper technique and build up strength and endurance gradually to avoid injury. It is also important to swim in safe and controlled environments, such as a pool with a lifeguard present.
