The history of transportation is very long and full of changes and inventions. Transportation started with walking, which is not exactly an invention since it only needs energy. People used to walk to get to places. If you wanted to get somewhere quickly, the only way to do that was to run.
Then people invented ways to transport themselves and objects from one place to another. The most popular invention was the wheel, and that was the beginning of many discoveries and innovations in transportation. It started in the 4th century BC, and once people had wheels, they could invent other ways to travel. They could attach wheels to the sides of a board and make it a wagon. Then they could tie that wagon to a horse to carry heavy materials to a destination.
Wheels led to what we have today: trucks, cars, and even boats and planes. They were also part of the oldest steamboat, which was invented in 1807. The steamboat was used to travel along the wide rivers of the United States and had giant wheels to push the water away and push the boat forward.
Moreover, wheels are essential parts of the airplane. Wheels of airplanes help control the speed for taking off and landing. They also help airplanes take off and land safely. The first example of wheels on an airplane can be seen in pictures from 1903 of the Wright Brothers and their successful powered aircraft. Even space shuttles and spaceships need wheels to land safely.
People predict that someday everyone will have a self-driving car. Self-driving cars are cars that travel without a driver and are controlled by robots and computer programmes. In the news nowadays, some car companies are trying their best to get the latest models of self-driving cars on the market by 2025.
Thanks to wheels, transportation has made it easier for people to travel and explore the world. It is incredible that we can now travel and see new things around the world so easily and comfortably. Besides, businessmen can now buy goods that would have been impossible to get from faraway countries in the past. Finally, transportation is something we cannot live without.
