The invention of the plane has greatly changed the world. However, it seems that its inventors, Orville Wright and Wilbur Wright, were not looking to change the world at all. Rather, they just wanted to fly like birds.

、
To solve the problem of heavier-than-air flight, the Wright brothers began working with gliders. There were two main challenges. The first was how to get the glider into the air. The second was how to control it once it was flying. For both problems, they found their solution by looking at how birds flew. After they solved these problems, they added an engine to the glider. Then, in December 1903, the world’s first plane flights were made.
What challenges were met

The high-speed train is one of the most important inventions in China. It was invented and developed by Chinese engineers. It was invented to make travel faster and more convenient, especially for long-distance journeys.
The main challenge was to build railways that could support very fast trains. The engineers solved the problem by using advanced technology and new materials. Finally, the first high-speed train was put into use in 2008.
The high-speed train has made travel much easier and faster. A journey that once took 10 hours can now be made in only 3 hours. As a result, people can travel between cities more freely, and the country has become much closer.
