In the process of continuous exploration and research of the earth, the strength of science and technology has been improved day by day. For example, inventions such as airplanes and submarines were born from the observation and learning of animals. While animals have many talents that humans can't match, such as birds soaring through the skies and whales resisting the pressures of the deep sea, humans also have their own strengths, which is why it's worth exploring in depth.
First, let's talk about airplanes. Before humans had airplanes, the sky may be a mysterious and desirable existence for us. However, with the birth of the airplane, we were able to conquer the blue sky. In fact, the design of the aircraft was mainly inspired by bats. We borrowed from the way bats fly, and we created the wings of the airplane. In addition, the aircraft is equipped with a radar system, the principle of which is also derived from the physiology of bats, which can use ultrasound to sense the surrounding environment and ensure flight safety.
Secondly, let's talk about submarines. Humanity's curiosity about the ocean led to the development of submarines as a means of underwater transportation. In the depths of the ocean, we can't breathe and it is difficult to stay for long periods of time, so submarines have become an important tool for us to explore the ocean. Early submarines were primitive and could only float on the surface, but after many improvements, today's submarines have the ability to dive underwater.
In general, whether it is an airplane or a submarine, their birth is inseparable from the observation and learning of animals. The invention of airplanes made it easier for us to get around, and submarines opened the door to the depths of the ocean.
