The wisdom of ancient Chinese is obvious to the world. Just like the four great inventions awe-inspiring people in the world still amaze the world today, and these inventions have also had a great impact on the development of the world. In the development history of many countries, there is still a feeling of praise and worship for the wisdom of ancient Chinese people. For the humble modern toys, it is also an important wisdom crystallization of the ancient Chinese. Even though the ancient Chinese people only regarded these inventions as toys two thousand years ago, they have become the core principles and stepping stones for the development of many technologies in modern times. Let us now take stock of the scientific principles in traditional toys and open our eyes.
1. Gyro-the "heart" of modern navigators
China had stone gyroscopes as early as the Neolithic Age four or five thousand years ago. Those who have played should know that no matter how uneven the ground is, it can turn very stably. This is the principle of "fixed axis" of physics. And the derivative of this principle is the navigator used to guide the direction on our modern aircraft, missiles, and rockets.
Second, the local telephone-the original long-distance communication device
The local phone is a childhood toy for many people. And the method is simple, only two paper tubes are needed, and a line can be whispered by straightening at a certain distance. The principle that this sound is transmitted remotely through the vibration of cotton thread is the prototype of our modern telephone.
3. Scrolling lights-the prototype of the turbine engine
The horse-drawn lantern is actually a rotating lamp. It is a kind of lantern. It was more common in the previous festive festivals. The candle was lit in the lamp. The heat of the fire caused the air flow, which caused the lamp axle to rotate. A picture of a general riding a horse, so turning it up is like a few horsemen chasing, so it is called a horse lantern. The turbine engine was invented using the mechanical principle of air expansion and contraction rotation. Turbine engines are mainly used in modern jet aircraft. It can be said that its appearance has triggered a revolution in aviation history in the world.
There are many examples in real life, such as bamboo dragonfly-the ancestor of the helicopter, ancient billiards-playing chess, etc. These traditional toys or play forms are all visible in our lives. Some people may think that the phone, gyroscope, bamboo dragonfly, etc. are outdated compared with modern toy products, and the fact is the same, but why they can not be eliminated for thousands of years, that is their small components The wisdom contained in them makes them shine for a long time, so do n’t underestimate traditional toys, maybe someone may create new technological achievements based on these toy principles.
