The river of nature seems to be flowing day and night without being subject to human will, but doesn't it also teach people how to understand the gravity of the earth, the inertial force of motion, and many other truths day and night, and teach people how to develop and utilize the potential of nature?
Metal, to human beings is more inspired, this kind of hard-looking things, after being melted by fire, can be turned into tools for human use according to human needs, and more importantly, it makes people understand that all kinds of substances have melting points and can be transformed into forms and energy states.
Humans have made airplanes based on sharks and radars based on bats. Humans invented airplanes based on the wings of dragonflies, radar based on the mouths and ears of bats, ships based on the shape of whales, and "electronic frog eyes" based on the eyes of frogs
Succeeded in the imitation of a very peculiar small gas analyzer by a nasty fly. It has been installed in the cockpit of a spacecraft to detect the composition of the gases in the cabin.

The downwind ears of jellyfish, imitating the structure and function of jellyfish ears, designed the jellyfish ear storm instrument, which can predict the storm 15 hours in advance, which is of great significance to the safety of navigation and fishery.
According to the visual principle of frog eyes, people have successfully developed an electronic frog eye. This electronic frog eye can identify objects of a specific shape with the same accuracy as a real frog eye. After the electronic frog eye is installed in the radar system, the anti-jamming ability of the radar is greatly improved.
This radar system can quickly and accurately identify specific shapes of aircraft, ships, missiles, etc. In particular, it can distinguish between real and fake missiles and prevent the real from being confused with the real.
Electronic frog eyes are also widely used in airports and traffic arteries. At the airport, it can monitor the take-off and landing of aircraft, and can issue an alarm if it detects that the aircraft is about to collide. In the traffic arteries, it can direct the driving of vehicles and prevent the occurrence of vehicle collisions.
According to the principle of the bat ultrasound locator, people also imitated the "pathfinder" for the blind. This pathfinder is equipped with an ultrasonic emitter that a blind person can carry to spot people on electric poles, steps, bridges, etc. Today, "ultrasound glasses" with a similar effect have also been made.

Biologists have ascertained that the Posidonia aquatic plant found is about 100,000 years old and is a member of a huge community of plants, covering an area of about 700 kilometers. Recently, the Posidonia aquatic plant community has been considered by biologists to be the oldest plant on the planet and an indispensable part of the local ecosystem, but the Posidonia aquatic plant has begun to decline due to the deterioration of the natural situation. >>>More
