One summer morning, the weather was fine, and the thrush was singing a sweet song in the tree. On the campus of Glasgow University in England, there is a man walking. He walked slowly up and down on the green lawn. He sometimes looked at the vast sky, sometimes at the winding playground, and sometimes frowned ... Suddenly, a smile appeared on his face and his mood suddenly became clear. He came up with an effective solution to the steam engine. He ran happily, his feet flying fast. In an instant, he appeared on the operating platform that accompanied him for many years. He is Watt, the inventor of the steam engine. Someone once said, "Watt invented the steam engine because he has superhuman genius and wisdom." Actually, it is not. To illustrate this problem, let's talk about Watt's diligent study and study. Make up a story
Enlightenment of water vapor
With the development of intellectual education, Watt became interested in some objective things, and he became curious and delved into them. This laid a good foundation for his later invention of the steam engine.
In Watt's hometown of Greenock, every family makes a fire to boil water and cook. Who cares about such a common thing? Watt left his heart. Is there a Huai? He watched his grandmother cooking in the kitchen. There is a pot of boiling water on the stove. The boiling water is boiling. The lid of the pot smacked and kept jumping up. Watt observed it for a long time and felt very strange. He wanted to know what the reason was, so he asked his grandmother. What makes the lid jump? "
Grandma replied, "The water is boiling, that's all."
Watt asked discontentedly, "Why does the water jump as soon as the lid is opened?" ? Is something pushing it? "
Maybe grandma was too busy to answer him correctly, so she said impatiently, "I don't know." What is the significance of children asking these questions? "
Instead of finding the answer with grandma, Watt was unfairly criticized. He was very uncomfortable, but he didn't lose heart.
For several days in a row, whenever cooking, he squatted by the fire and observed carefully. At first, the lid was very stable. After a while, the water will boil and make a loud noise. On the ground, the steam in the pot came out and pushed the lid to jump. The steam kept rising, and the lid kept beating, as if a magician was hiding inside, doing tricks. Watt almost cried out for joy. He opened the lid, closed it again and again, and verified it again and again. He also covered the cup and spoon that sprayed steam. Watt finally figured out that steam pushed the lid to jump, and the power of this steam was not small.
Just as Watt was in high spirits and ecstatic, grandma spoke again: "You child, you don't know good or bad. What's so funny about the kettle?" Go away! " She said casually.
His grandmother is too impatient and subjective, and if she neglects it casually, it will almost dampen Watt's self-esteem and enthusiasm for exploring scientific knowledge. Old man, you don't understand Watt's heart at all, do you? What a revelation water vapor is to Watt! Isn't the physical phenomenon that water vapor pushes the lid of the kettle to jump off the water bottle the source of Watt's understanding of inventing the steam engine?
1769, watt changed the steam engine into a single-acting engine with great power. Later, after many studies, the trial production of the new steam engine was completed in 1782. With the linkage device on the machine, the simple motion turned into rotary motion, and the perfect steam engine was successfully invented.
Due to the invention of the steam engine and the developed coal and iron industry in Britain at that time, Britain became the first country in the world to use steam to drive iron "seagoing ships". /kloc-in the 0/9th century, the reform of maritime transportation began, and some countries entered the so-called "steamboat era". Since then, ships have been sailing on the boundless ocean. Then %B
