Can we ride fish?

Recent discoveries in the context of the  Botai culture  suggest that Botai settlements in the  Akmola Province  of  Kazakhstan  are the location of the earliest domestication of the horse. I f we start with when we start to ride horses,  since 5000 years ago we've been start to ride animals. Land animals are possible to tame as the same mammals, but fish are not.  1. Most fishes cannot reach a certain level of learning. 2. People are susceptible to decompression illness for varying depths but fish and other water creatures are not.  Dolphins and seals, for example, avoid divers(decompression illness) by minimizing the influx of nitrogen by contracting one lung as they rise from the deep sea to the surface. as they use a lot of oxygen stored in their blood and muscles.  In other words, if we can tame dolphins ,for example, and handle the formation of vascular nitrogen bubbles in our blood vessels, we may be able to ride fish (sea...

Why won't the car roll around?

 I wondered how the rolling wheels connected to the carbody that is parallel to the ground.  I could have guessed that cogs and bearings would be in between. But can they withstand that enormous weight? I was curious about the detailed structure. So I decided to find out. Drive shaft, Differential, Suspension, Wagon wheel ..  In the process of learning, I learned various interesting concepts. But I haven't found anything I'm really curious about.  However, while watching a video explaining how the engine works, the concept of how to change the rotation into a linear force emerged. I thought this is it. Then I got to know the bearing and found the real answer. Bearings are mechanical elements that reduce friction between moving objects. In short, several small balls play a role in transmitting one turn to the other. *Tribology : the science of wear, friction and lubrication, and encompasses how interacting surfaces and other tribo-elements behave in...
