At the end of the 18th century, after scientists dissected and studied electric fish, they finally discovered a unique electrical organ inside the body of electric fish. These power generating organs are composed of many translucent disc-shaped cells called electric plates or discs. Due to the different types of electric fish, the shape, position, and number of electric boards of the generator are all different. The electric eel's generator is prismatic and located in the muscles on both sides of the tail spine; The electric generator of the electric ray is shaped like a flat kidney, arranged on both sides of the midline of the body, with a total of 2 million electric boards; The generator of electric catfish originates from a certain gland, located between the skin and muscles, with approximately 5 million electrical boards. The voltage generated by a single board is very weak, but due to the large number of boards, the voltage generated is very high.
In the early 19th century, Italian physicist Volt designed the world's earliest Volt battery based on the electric fish's power generating organ. Because this type of battery is designed based on the natural generator of electric fish, it is called an "artificial electrical appliance". The study of electric fish also provides people with the following inspiration: if the power generation organs of electric fish can be successfully imitated, then the power problems of ships and submarines can be well solved.
Nature provides people with many inspirations, and as long as you observe carefully, you can definitely create things that are beneficial to people.
One summer evening, I was playing on the playground. When I saw many locusts in the grass, I thought to myself, catch a few locusts to play with. Thinking of this, I quietly walked into the grass and saw a locust resting on its stomach. I quickly pounced on it, and with a whoosh, the locust disappeared without a trace. Wow! How could it jump so high! How did it jump so high and so far? What force made it jump so high and so far? I returned home with a mind full of doubts and decided to study locusts thoroughly.
The next day, with great effort, I caught a locust and took it home for observation. The locust has a pair of wings and six legs. Its hind legs are long and strong, looking very powerful, but its front legs are thin and short. Is it powered by its hind legs? With a doubt in mind, I placed the locust underground, and the locust could have thought I had let it go and tried to jump with all its might. This time, it was about fifty centimeters wide. I thought to myself: Oh my goodness! How powerful these full hind legs are! No wonder you jumped so high and so far! To prove that all my ideas were correct, I searched the internet and the result was exactly what I thought.
The mysteries of nature are endless, it's truly magical! We need to explore.
Legend has it that one day, Lu Ban was thinking of building a tool that could both block rain and carry with him. At this moment, it began to rain, and Lu Ban hurriedly ran towards home. On the way, he saw several children playing by the pond, each holding fresh large lotus leaves in their hands. Lu Ban approached and observed closely that there was a thin film on the lotus leaf, on which rainwater dripped and directly slid down. Lu Ban was inspired and, following the results of the lotus leaf, made a wooden frame, then covered it with sheepskin to make the earliest umbrella. Everyone cheered after seeing it! From then on, umbrellas have played an important role in people's daily lives.
There are many examples of this, for example: people felt that airplanes could not fly stably and glide for a long time, so they imitated the long and wide wings of eagles to transform airplanes and invented the glider; For example, the eyes of frogs are very sensitive to moving things, but they are blind to stationary things. Scientists have utilized this feature to invent the "electronic eye", which can help airport staff better command the landing of airplanes.
There are countless examples like this, and nature has given our scientists a lot of inspiration. Of course, there are many mysteries in nature that await us to continue discovering and exploring. Humans can only make continuous progress by exploring the unknown. Nature is really a good teacher for humans!
A chameleon changes color because its skin contains a special type of cell. When the cell "sees" things around it, it becomes the corresponding color and hides itself. Doing so can not only protect oneself from being discovered by natural enemies, but also help oneself hunt. This is really amazing! The Sichuan butterfly hiding under the sea is also based on this principle. Once, scientists placed it on a chessboard and it immediately turned into a black and white color.
From the chameleon, I gained inspiration that I want to invent a chameleon car. The hard surface of this car is composed of small squares, which contain rich pigments. It can change color like a chameleon!
Due to its special function, the color of a car can automatically change with the seasons. Spring turns red, making people feel warm; In summer, it turns blue, making people feel cool; Autumn turns yellow, making people feel at the scene of a bountiful harvest; In winter, it turns snow-white, making you feel like wandering in a sea of snow. In addition, it has military applications. You just need to press the "color change button" and it will pop up 8 scanners, sensing the surrounding environment and immediately changing the color. The car can be "invisible" and the enemy cannot easily detect it. In this way, it is much more convenient to perform tasks.
I believe that humans will learn more knowledge from nature's "teachers"!
Frogs have very special eyes. They are very sensitive to moving things, but they are very slow to see stationary things. People have utilized the characteristic of frog eyes to invent the "electronic frog eye", which enables airport personnel to accurately command the landing of aircraft.
The leaves of Plantago are arranged in a spiral shape, which provides ample sunlight. Therefore, the houses built by architects in this shape can also allow each room to enjoy warm sunlight.
People still have many inspirations from nature. For example, the "Newton's law of universal gravitation" was found in "falling from an apple"; Invented the "anti G flying suit" from the "body structure of giraffes"; Invented the "modern night vision device" from the "Rattlesnake"
From this, it can be seen that the vast world is full of wonders. As long as we carefully observe and dare to explore, even a small grass will have its wonders and bring us millions of inspirations. So while enjoying nature, we also need to discover and observe many mysteries within it, and make reasonable use of it to provide more convenience for people and make their lives better.
